Paralysis in dogs

A dog’s ability to move and perform its daily activities depends on the ability of the brain, spine, nerves, and muscles to coordinate together.

This complex communication system exchanges information when nerves in the brain send messages to the body about the outside environment, and the body sends messages to the brain about what it is experiencing in the environment. These messages are transmitted through nerves in the spinal cord, which are embedded in the spine or spine. Together, the nerves of the brain and spinal cord make up the central nervous system. Trauma to any part of the nerve pathways can lead to poor communication, or a total lack of communication between the brain and the body, leading to an inability to coordinate body movements.

The spine is made up of a set of 24 bones called vertebrae, which are separated from each other by small cushions called intervertebral discs. Together, the vertebrae and intervertebral discs protect the spine from damage. Trauma to the vertebrae or discs can create vulnerability in the nerves of the spinal cord, leading to new disorders to the neural pathway.

When a dog experiences paralysis, it is often because communication between the spinal cord and the brain has been disrupted. In some cases, the dog is not able to move its legs, a state of total paralysis, and in other cases, there may still be some communication between the brain and the spine, and the dog will only appear weak or have difficulty moving its legs, a condition known as: partial paralysis. There are also cases where a dog may be paralyzed on all four legs (quadriplegia), and in others, the dog may be able to control movement in some of its legs, but not all. This is determined by the location of the trauma, occurring in the brain, spine, nerves or muscles.

Some breeds are more prone than others. Dogs that are close to the ground with elongated backs, such as dachshunds and bassets, are commonly affected by ruptured vertebral discs by putting pressure on the spinal cord, a condition known as intervertebral disc disease. Some breeds are genetically predisposed to a condition called degenerative myelopathy (MD), a disease that attacks nerves on the backs of older dogs (more than seven years old). It is a slow action, a progressive disorder that eventually leads to paralysis of the hind legs. Breeds affected by this disease are the Welsh corgi, boxer, German shepherd, Chesapeake Bay retriever, and Irish setter.

Symptoms:

Not able to move all four legs (quadriplegia)

Not able to move the hind legs (paraplegia)

Walks with front legs while dragging hind legs

There may be pain in the neck, spine, or legs

Can’t urinate

Not able to control urination, urine dripping

Not able to control defecation

Constipation

Causes:

Canine degenerative myelopathy (MD) – related to the gene of German shepherd, boxer, Welsh corgi, Chesapeake Bay retriever, ages 7-14 years; the cause is unknown

Slippage of the discs in the back – intervertebral disc disease

Spondylodiscitis – bacterial or viral infection in the bones of the spine (vertebrae)

Infection or inflammation of the spine

Distemper

Meningomyelitis – viral or bacterial infection of the brain, leading to poor communication of nerve impulses

Polymyositis – infection or inflammation in the muscles

Polyneuritis – inflammation of the nerves

Embolism – obstruction of blood flow to the spine

Aortic embolism – obstruction of blood flow to the back legs

Tumors or cancer in the spine or brain

Tick paralysis as a result of tick bites

Rocky Mountain Fever

Botulism – bacterial toxins

Myasthenia Gravis – severe muscle weakness

Fibrocartilaginous embolism the fluid inside an injured disc enters the arterial system and settles in the spinal cord, creating a permanent embolism, or blockage, is irreversible, but not progressive.

Hypothyroidism – Low thyroid level

Spinal injury

Malformation of the spine or vertebrae

Diagnosis:

You will need to give a complete history of your dog’s health, the onset of symptoms and possible incidences that may have led to this condition, such as tick bites, or recent injuries from jumping or falling. During the physical exam, your veterinarian will pay close attention to how well your dog is able to move his legs, and how well he is able to respond to reflex tests. The veterinarian will also test your dog’s ability to feel pain on all four legs, control of the head, spine, and legs for signs of pain and alertness to the touch.

All of these things will help your veterinarian locate the place in your dog’s spine, where nerves or muscles are having problems. Basic laboratory tests include a complete blood count, a biochemical profile and a urinalysis, which can determine if your dog has a bacterial infection, a virus or a toxin reaction, which is interfering with nerve pathways. X-ray images of the spine can show evidence of an infection, a malformation of the vertebrae, or a herniated disc that is pressing against the spinal cord. Other conditions that can lead to disruption of nerve pathways may be evident on an X-ray, such as tumors, obstructions, or inflamed nerves.

In some cases, your veterinarian may order a special X-ray called a myelogram. This process uses an injection with a contrast agent (dye) into the spine, followed by X-ray images that will allow the doctor to see the spinal cord and vertebrae in more detail. If these imaging techniques aren’t helpful, your veterinarian may order a computed tomography (CT) scan, or magnetic resonance imaging (MRI) of your dog’s brain and spine, both of which provide a very detailed picture. In some cases, your veterinarian may take a sample of the fluid around the spine, for analysis, or sample of the muscles or nerve fibers for a biopsy. These tests can determine the presence of an infection in the brain or spine.

Treatment:

The course of treatment will depend on the cause of the paralysis. If your dog is unable to walk, urinate, or defecate on his own, he will most likely be admitted to the hospital while his veterinarian will work to deliver a diagnosis. From there your veterinarian will track your dog’s recovery and progress. If your dog is in pain, he will be given medication to help control the pain, the bladder is emptied several times a day by catheter, and your dog will be physically moved to make sure he doesn’t get ulcers from staying in one place for too long. There are several products that will help you spend time still without getting damaged, such as mattresses. If the cause of the paralysis is an infection or a herniated disc, the condition will be treated with either medication, surgery, or therapy. Anti-inflammatory drugs that may be natural and specific such as imflamex will be used to reduce inflammation of the nerves. Tumors or blockages of blood flow can be repaired surgically, depending on the vulnerability of the location. Some paralyzed dogs recover very quickly. Depending on the severity of the illness, your dog may stay in the hospital until he is able to walk, or your veterinarian will decide to send your dog home with a guide to provide care and recovery at home. Your veterinarian will establish a plan to review the progress of your dog’s treatment and adjust it accordingly.

life and a lot!

Your veterinarian will help you make a plan for your dog’s care at home. Occasionally, the dog may resist care due to pain, but assertive and gentle care will help decrease fear reactions.

It is important that you take care of your dog properly so that he can fully recover. Carefully follow all instructions from your veterinarian. If your veterinarian has prescribed medication, be sure to administer all treatment, even after your dog appears to have fully recovered. In most cases, a canine wheelchair can be of great help, either for the rehabilitation process or as a simple means of transporting the immobile part of the animal. Most wheelchair dogs adapt very well and continue to enjoy their life.

Treatment of elbow hygroma

injuries, most commented, Pathologies, Treatments, vet

Treatment of hygroma of the elbow

Elbow hygroma is a disease that mainly affects large short-haired dogs, such as Big Danes, Greyhounds and Dalmatians. In dogs with elbow hygroma, a fluid-filled sac appears on one or both of the dogs’ elbows. In rarer cases, hygromas can develop in the hock. In many cases, elbow hygromas do not cause pain or difficulty. However, they can become infected, which can be painful for the dog and requires treatment. Other animals susceptible to developing hygromas are dogs that are not very active or are recovering from illness or injury.

Causes
Hygromas develop because of recurrent trauma to a dog’s elbow or elbow. For example, resting constantly on wood, cement, or other hard surfaces can cause stress on the joint and cause hygroma. This condition mainly affects large dogs, as there is a greater weight on their elbow joints when they are lying down.

Bandage
In some cases, bandaging a dog’s elbows can help prevent hygromas from getting worse. Bandages will prevent contact with hard surfaces and in turn avoid problems caused by hygroma. In addition, some products such as the canine elbow protector or the dog knee protector will prevent the hygroma from having additional contact with the hard ground. Ask your veterinarian how you can help your dog.

Drainage
Some veterinarians recommend that hygroma fluid be drained with a needle or syringe. Getting the fluid out is not considered an effective treatment because the needle can cause an infection. In addition, drainage can only improve the condition temporarily. If the dog continues to lie on hard surfaces, the hygroma will become larger, that is, the drainage will have to be done on a regular basis.

Surgery
Some veterinarians may recommend surgery to treat elbow hygroma, especially in cases where there is infection or when the hygroma has ulcerated. In surgery, the skin must be drained and removed. Since hygromas can grow quite large, it may be necessary to make skin grafts to cover the affected area. Healing from surgery takes about a month, and the dog will need to wear a splint during recovery to protect the affected area.

Prevention
The best way to prevent your dog from developing an elbow hygroma, or to prevent an existing one from worsening, is to provide the dog with a soft surface for him to rest and sleep. If there is no carpeted area available, make the dog a soft bed and leave it where he likes to lie down. In the event that the dog is inactive because he is recovering from an illness or injury, have him get up and move (at least enough to change the position he is lying in) several times a day.

Osteoarthritis in dogs

Pathologies, Treatments, vet

Canine osteoarthritis is a very common disease in dogs. It appears as a result of the inevitable evolution of a joint that ages or becomes increasingly fragile due to trauma or malformation. This is a very painful condition that needs to be treated right away. It can affect all the joints of the body, both those found in the anterior and posterior extremities, as well as those that form the spine. In the case of senior dogs, the most common is that this disorder affects several joints at once.

The articular surface is covered by a tissue called cartilage, which plays a role very similar to the shock absorbers found in cars. In addition, it prevents the underlying bone from deteriorating due to the repeated rubbing to which it is subjected by continuous movement. Osteoarthritis is characterized by a progressive destruction of this cartilage and by an abnormal bone proliferation at the edge of the articular surfaces known as osteophyte, also called ‘parrot beaks’ when they are located in the spine. The affected joints lose elasticity, cause pain and prevent the animal from moving normally.

Evolution of deterioration
As a rule, this ailment affects, first of all, the high joints of the limbs: hips and knees, shoulders and elbows. Symptoms are more or less important depending on the number of joints affected. However, there is an unequivocal sign that makes us intuit that the animal is affected. Lameness usually manifests itself when the dog gets up and starts up after remaining immobile for a long time.

The pain prompts the animal to avoid support on the affected limb and, being impeded, stops running, and of course, jumping. As it evolves, the pain increases. When making certain movements, the dog emits small moans, it is even possible that the animal is irascible and tends to present aggressiveness when we try to manipulate the affected joint.

In more advanced cases, the joint may be partially blocked, making it impossible to perform certain movements. At this point, the animal hesitates to use the diseased limb. In addition, this lack of activity leads to a significant deterioration of the musculature surrounding the joint. As a result, the diseased area begins to atrophy, which increasingly complicates its use.

Two fundamental types
As a general rule we distinguish two types of osteoarthritis: primary and secondary. The first type usually affects elderly animals and appears due to the normal aging suffered by the joints due to the passage of time. In fact, it is a progressive and inevitable wear of the articular cartilages. Usually, this type of osteoarthritis affects different points at the same time.

As far as secondary canine osteoarthritis is concerned, it appears as a consequence of a triggering factor, which causes the affected joint to stop functioning normally. For example, this type of osteoarthritis can appear due to trauma – a sprain, a fracture, etc. – or due to a birth malformation, such as hip dysplasia.

Another very common cause that causes the appearance of secondary osteoarthritis is obesity. If you do not control the diet your friend can have a weight well above the average that we find in the breed. The joints are not made to support such a significant overload of kilos, so they deteriorate easily. Unlike primary osteoarthritis, secondary osteoarthritis can affect animals of all ages and, as a general rule, usually affects only one joint.

Issue a diagnosis
The diagnosis of this disease can be based on three factors: the pathological history of the animal, gait examination and manipulation. When studying the history, the veterinarian must take into account old joint fractures, injuries that the animal has suffered a long time ago, as well as possible sprains. When observing the gait will look at whether the dog limps, even if only very slightly and incipiently, since lameness is an unequivocal symptom of the disease. Finally, when manipulating the affected area it is very possible for the animal to show signs of pain.

Often, the region in which the diseased joint is located is usually somewhat deformed due to osteophytes and muscle atrophy caused by the absence of physical activity. Many times a characteristic snap is detected when we move it. Through the radiological study, the animal health specialist will be able to determine the severity of osteoarthritis and establish the most appropriate treatment. Among the possible treatments, the appearance of specialized supports for some limbs that can effectively combat the deterioration of the animal’s quality of life stands out. The use of these supports is effective and has proven in countries such as the USA to be treatments as innovative as successful, however their use should be consulted with the veterinarian or animal physiotherapist.

Elbow dysplasia in dogs

injuries, Pathologies, vet

Elbow dysplasia is a very common degenerative disease in young dogs. The elbow of dogs is one of the most congruent and stable joints of the body, allowing, due to its complexity, two axes or degrees of supination-pronation movement of the forearm and flexion-extension. Its complexity is given by its composition: humeroradial joint, humeroulnar and, proximal radioulnar.

Elbow dysplasia was initially used to describe the non-union of the anconeal process (AUP). Currently, osteochondritis dissecans (OCD) of the medial condyle of the humerus, the fragment of the coronoid process (FPC) and, the incongruence of the elbow (INC) are also included within this term. When one of these ossification defects occurs in an elbow, inflammation originates and over time an osteoarthritis is triggered in which cartilage degeneration occurs; for that reason, all these conditions are commonly associated with osteoathrosis of this joint and are an important cause of pain and claudication of the forelimbs in large and giant breed dogs such as the German Shepherd, Labrador, St. Bernard, Rottweiler, Neapolitan Mastiff, among others.

Of genetic origin multifactorial, especially in OCD and FPC. It affects males more than females and can occur uni- or bilaterally. The genetic component is the one that has the greatest influence although, the appearance of this pathology can also occur due to food, weight, environment, quality of ligaments, a lot of physical exercise or trauma.

The first symptoms may occur at 4-5 months when the dog shows exercise intolerance, lameness when starting a movement or after prolonged exercise. There are dogs that do not show signs of affection in the elbow until advanced ages where the process of osteoarthritis is very evolved. Others manage to maintain a normal degree of activity throughout their lives.

The fact of making a premature radiological diagnosis makes it possible to establish an adequate treatment and avoids the formation of osteoarthritis that produces pain and functional limitation of the elbow throughout the life of the animal. The diagnosis can be complemented with diagnostic tests such as CT or MRI

The evolution depends on the degree and type of injury, but it is usually unfavorable without surgery. Surgical treatment is good if degenerative changes in the joint have not yet occurred. In any case it is necessary to perform a good rehabilitation in order to:

Speed up the recovery process
Eliminate pain and inflammation
Decrease lameness
Maintain and/or improve range of motion
Maintain muscle tone, mass and strength
Minimize or slow down the effects of joint degeneration – osteoarthritis
Avoid compensation at the level of the neck, spine and extremities
Give the maximum capacities so that the animal is functional and that it, with a good quality of life

Physiotherapy treatment varies depending on the animal and the state of the lesion. It is important to start as soon as possible with the treatment so that it is effective and, to avoid drying them as reduced mobility and / or chronic pain.

The animal goes through different phases until its full recovery. It is essential to gradually achieve the objectives set. The recovery process is terminated when the animal is able to perform daily activities.

During the first three days after the intervention, it is important to act on inflammation and pain and prevent muscle atrophy and decrease in the joint arch from appearing. For this, passive techniques are used that reduce inflammation, produce analgesia and help maintain tone, mass and the arc of mobility. Among these techniques there are electrotherapy (segmental TENS and muscle electrostimulation), massage, passive mobilizations and cryotherapy (cold).

In older dogs or dogs that have not been intervened, the objectives will be the same as in animals that have gone through an intervention. It is important to eliminate pain because, with pain you can not work.

It is important from the beginning to massage and move the affected elbow as long as there is no veterinary contraindication and, respecting in the case of fixation, the period of healing and union of the fixed parts. Massaging and moving the affected area and limb helps maintain mobility, prevents loss of mass and tone and works the proprioceptors.

A gentle mobilization combined with different massage techniques help decrease inflammation and reduce pain.

With TENSat the segmental level we can produce analgesia and decrease the amount of drugs administered. There are animals that have intolerance to certain drugs that produce analgesia and with TENS the pain can be reduced. TenS can also be used directly on the injured or operated area, as long as there is no osteosynthesis material underneath, since an internal burn could occur.

Muscle electrostimulationhelps prevent the onset of atrophy and maintain muscle mass and tone. With electrical stimuli we can stimulate nerve conduction.

At the beginning and end of the session the coldis used since it has properties that act on the decrease of the inflammatory response, edema and pain.

From the fourth day and during the next two weeks when the inflammation and pain have disappeared it is time to introduce simple active exercises such as shaking hands or small walks on a leash to force the animal to make an equal support with the four limbs and thus, prevent a decompensation between limbs from appearing due to not having a correct support on the ground. The walks is an exercise that increases the duration until full recovery.

Once the stitches have been removed, the animal can be introduced into the water. The advantages of water are used to improve recovery. Hydrotherapy (underwater treadmill) facilitates the station of the animal without loss of balance and, thanks to flotation, without having to support all its weight. In addition, flotation allows animals with bone pain and low muscle mass to work. The pressure of the water exerted on the body of the animal increases the sensitivity and decreases inflammations and edemas. The work in the water, underwater tapes or swimming increases as the animal recovers. In addition, with water, we can recover the motor pattern, increase mass, tone and strength, work on respiratory capacity and maintain and / or improve mobility.

Once the acute phase has passed 48-72 hours and without risk of infection or inflammation, heat can be introduced that helps to elastify the tissues, decreases pain and increases vascularization among others.

The use of boards, plates, balls and trampolines are important to work on balance, proprioception and above all the integration of the affected limb.

It is already in the last phase, from two weeks, when the dog has integrated the gait pattern, exercises are performed to improve the quality of movement. They are more complex active exercises to integrate the affected limb or limbs. With active and proprioception exercises it is possible to increase muscle tone, mass and strength; coordination and balance and range of motion are worked on. Rails with different surfaces, cones, bars, circuits, up and down stairs and ramps (staircase with inclined plane) are used.

Throughout the recovery treatment and in animals with developed osteoarthritis it is essential to reduce the weight on the joints of the elbows. For this purpose , special support harnesses for elbows are used. In addition to decreasing weight, pain is reduced and does not hinder movement, the animal feels more comfortable; the joint is protected at all times from chafing and blows and helps maintain the heat that the animal gives off, which leads to a relief of the affected area.

At home, special care should be taken for animals suffering from elbow conditions. This care is necessary during and after treatment:

Avoid slippery floors
Avoid ramps and stairs at the beginning of treatment in operated animals and in animals that do conservative treatment. Once rehabilitated, ramps can be used to help get on the sofa and the car, since it is recommended that they do not do it alone, there could be a recidivism.
It is recommended that they rest on soft and clean surfaces, but that they are firm enough to help the incorporation of the animal thermal mattress for dogs
Keep skin clean and dry skin
Use special plates at your height so as not to strain the elbow joints
Correct diet and weight control. Being overweight harms the joints and generates more pain for the animal

It is very important to create an exercise routine and environment to help keep the animal comfortable and with quality of life.

The 7 Basic Questions About Hip Dysplasia

Pathologies, Treatments, vet

1. What is hip dysplasia?

It is one of the most frequent diseases in dogs, especially large breeds.

2. What is the disease?

In a mismatch between the head of the femur and the acetabulum, that is, a bad gear of the hip joint. The femoral head is partially outside the acetabulum and the hip cannot work properly.

3. Does it affect some races more than others?

Yes, hip dysplasia practically does not exist in Greyhounds and yet it is very common in San Bernardo and Mastines. It is also quite common in the German Shepherd, the Golden Retriever and the Rottweiler among other breeds.

4. How to know the severity of dysplasia?

There are several degrees of dysplasia, but there are also different ways to measure it, the most common being an X-ray that should be done on dogs near the year of life. This x-ray must be performed in a very specific position and with the muscles relaxed, so it is usually necessary to anesthetize the dog.

5. What are the symptoms?

Normally lameness in dogs from 5 to 10 months but can remain without problems during youth and adulthood and debut with major problems in the geriatric period. Movement to the sides of the hips may also be indicative of hip dysplasia.

6. Does it have anything to do with osteoarthritis?

They are two different problems, but hip dysplasia, the mismatch of the joint, can cause over time that this joint degenerates and ends up suffering from osteoarthritis in the hip. Osteoarthritis is what hurts, especially in old age. Dysplasia may be more responsible for the dog’s development of osteoarthritis.

7. Is there treatment?

There are several treatments, various surgeries before the year of life and other methods such as hip prosthesis when the dog is older and has finished growing.

We also have palliative treatments such as anti-inflammatories or cartilage protectors (chondroprotectors). In very serious cases you can put a canine wheelchair and the dog continues to walk but without bearing the burden of its weight.

Electrostimulation in dogs

injuries, Pathologies, Treatments, vet

Electrostimulation for muscle potentiation

Electrostimulation is a very useful tool to enhance the muscles of a dog that has suffered an injury or surgical intervention and as a result has muscle atrophy.

We can use electric current to stimulate the muscles, enhance it and make it work, it is specifically indicated in cases of muscle atrophy, and especially in cases where the dog can not do active work. If the dog can do active work, electrotherapy will be a support, never the main source of work.

Form of the impulse that we will use will be the Rectangular, symmetrical biphasic the main authors indicate it: Thepaut Mathieu 1992, Kramer 1984, Bircan 2002

Human electrostimulation apartments can be adapted to electrostimulate dogs without too many problems, but we must ensure that we can vary the frequencies, and especially the amplitudes of the electrical impulse to adapt well to the characteristics of the dog.
There are no good studies of Cronaxia in dogs, the approximate values are 0.3 human, 0.2 Horses and in dogs by studies of less depth intuit similar values;
Sawaya – Meallier 2006, Brodart 1998, Coarasa 1999, Ramon 2007
The Intensity according to Hultaman 1983, and Ogino 2002 should be elevated with visible contraction, without reaching the limit of pain but discomfort. The dog must comfortably withstand the session but the muscles must work intensely.

The frequency will be marked according to the objective, various authors validate this option: Pougheon 1992, Busko 1989, Vanderthommen 2002.

Objective	Frequency	Treatment time	Standby time
Relaxation:	5 Hz	Continuous	0
Heating:	5 Hz	Continuous	0
“Endurance”:	10-20 Hz	9	2
Atrophy:	33 Hz	6	6
Strength:	50- 100 Hz	5	25
Explosive force:	100-200 Hz	3	30

The parameters may vary slightly according to individual cases.
Rest time can be adjusted if it is active, it is advisable to use ramps before strong muscle contraction.
The intensity should always be the maximum with relative comfort.
Total time between 10 and 30 minutes depending on the phase of the injury, fatigue the muscles excessively does not help to enhance the muscles correctly.

It is important to have a device that meets all the requirements, if it is going to be used by a canine rehabilitation center or veterinary hospital, a more professional desktop apartment is recommended and with it we can use specific programs for each of our patients.

The use of rubber electrodes and contact gel is equally recommended in animals with hair.

Can chondroprotectors help?

Pathologies, Treatments, vet

Osteoarthritis is the most frequent health problem in dogs and also in cats of a certain age. 20% of dogs over one year old suffer from joint disorders; more than 95% of cases occur in dogs aged five years or older.

Lameness is the main cause of consultation with the veterinarian of dogs with osteoarthritis, immobility, refusal to take walks, difficulties getting up, persistent lameness, stiffness when waking up and chronic pain are other common signs. It may develop gradually or appear suddenly following minor trauma or excessive exercise.

The pain is due to the loss of thickness and quality of the articular cartilage, it degenerates to produce the practical disappearance of the same, inflammation of the joint capsule and osseous reaction (osteophytes).

Chondroprotectors are food supplements that promote hydration and nutrition of articular cartilage.

The composition of the most common chondroprotectors is Glucosamine, hyaluronic acid and chondroitnin sulfate.

Glucosamine increases the synthesis of matrix components by chondrocytes. The synergistic action of Chondroitin sulfate and Glucosamine enhances the effect to this chondroprotector.

Hyaluronic Acid contributes to the correct maintenance of synovial fluid, essential to recover joint mobility.

Chondroitin Sulfate is one of the main constituent elements of cartilage, together with proteoglycan, gives cartilage mechanical and elastic properties, contributes to a correct hydration of cartilage.

Vitamin E prevents against the appearance of osteochondral disorders and limits the formation of free radicals associated with arthropathy.

Chondroprotectors, being a natural product present in the body, does not produce adverse effects. It is not a medicine, therefore it is not necessary a prescription nor is it necessarily sold in pharmacies. Unlike other treatments, it can be given for prolonged periods of time without harming the body.

We can administer it both in dogs of breeds with special incidence of hip dysplasia during their growth and in older dogs that already have problems.

Administration in dogs during the growth period can be started from 3 months of age of the animal until the growth period is completed (around 8 to 10 months of age depending on the breed)

There are several chondroprotectors on the market, in Ortocanis we have made a selection of the best chondroprotectors looking for quality and effectiveness of the active ingredients.

The application of therapeutic ultrasound in dogs

injuries, Pathologies, Treatments, vet

It is one of the most used instruments in physiotherapy. It is a device that emits acoustic waves of much higher frequencies than those audible by humans. The frequency used as a therapeutic tool is 1×106 Hertz, i.e. 1 Mega-Hertz (MHz), so they are not audible by any mammal.
Usually in veterinary clinics and hospitals, ultrasound is used for ultrasound scans that use the same type of wave. The difference is power, frequency and application time.
In therapeutics we use frequencies of 1MHz for deep treatments, up to 8 cm and frequencies of 3MHz for more superficial problems. The power ranges between 0.2 and 3 Watts / square centimeter.

Effects on tissues:

The main effect of ultrasound on tissues is anti-inflammatory. We usually use it in tendons, joints or inflamed muscles; it has excellent results in both acute injuries and chronic injuries, although we must adjust the powers.

The analgesic effect is another of the most sought after in rehabilitation, normally when we deflate a structure we manage to reduce the pressure in the nociceptors that are the receptors in the body that send the painful signals, by reducing the pressure in these receptors, we reduce their stimulation and therefore decrease the intensity of the signals they send until they disappear. If there is no sign of pain, there is no perception of it.

When we have a fibrosis in the different soft tissues: muscles, tendons or ligaments, we can apply continuous and then pulsating ultrasound at maximum power. This way we will find a good defibrosing effect.

Another of the classic applications of ultrasound is the application in muscle contractures, with ultrasound we can reduce and even eliminate them.

Continuous ultrasound generates heat by the vibration of the molecules and both the pulsating and the continuous increase the permeability of the membrane, which is what favors together with the mobilization of the molecules the anti-inflammatory effect.

Application:

Ultrasound must be applied by moving the head all the time that the treatment lasts, either making small circles or following the direction of the treated tissues rectilinearly. If we do not do so, especially in continuous mode, we can damage tissues and produce significant burns.
It is necessary to use a means of contact, either contact gel or directly in direct immersion (sub-aquatic ultrasound).
It is also important to take into account the hair of the animal, this hinders the transmission of ultrasound and therefore it is very interesting to be able to shave the dog before applying the ultrasound session

Approximate time between 5 and 15 minutes
Power between 0.2 and 3 Wats/^cm2
There are different head measurements depending on the needs.

Directions:

Ultrasounds can be used in any pathology of the dog that occurs with joint or soft tissue pain, such as tendonitis, bursitis, arthritis, bruises or major bruises.

We can also use ultrasound in chronic problems such as hip dysplasia, elbow dysplasia, knee osteoarthritis, or hip osteoarthritis.

All surgical interventions produce an inflammation of the tissues that have been operated, ultrasound is a very good tool to control inflammation and post-surgical problems such as rupture of the cranial cruciate ligament, patella dislocation or others.

Hip dysplasia Irresponsible breeders, feeding, environment?

Curiosities, injuries, Pathologies, Treatments, vet

Hip dysplasia Irresponsible breeders, feeding, environment?

Currently, with only three months of age it is possible to know the existence of small anomalies in the conformation of the hip/femur joint, which will lead to dysplasia.

Origin of hip dysplasia in dogs:

In colloquial language (today we avoid veterinary terms) hip dysplasia is a “failure” in the head joint of the femur-hip. If the head of the femur is not lodged in the hip perfectly, there is a deterioration of the cartilage that protects the joint, and that deterioration is degenerative and irreversible. But why does hip dysplasia occur?
Genetic inheritance. Hip dysplasia is inherited, and if breeders do not perform the necessary tests to know that their dogs are free (certified X-ray) and that previous generations too, puppies can suffer from it. Many breeders (and more particular) ignore these x-rays (eye, there is no breed safe from the disease). Hopefully they include a clause in the sales contract in which they will give you a puppy if you prove that the one you have bought has dysplasia (as if they were appliances).
Environmental factors. In the period of growth (until the year, but especially critical the first six months of life), slippery floors, sudden exercises, jumps … Puppies with a limit hip can aggravate their situation if care is not taken in these critical months, and vice versa, they will be able to lead a perfectly normal life if they develop correctly in these months (even if their hips are not perfect).
Feeding. The months in which dysplasia develops are those of growth, and the slower the puppy grows the better. Foods very high in protein have been linked to the onset of dysplasia. Chondroprodectors help during growth (in predisposed individuals or breeds, always under veterinary supervision).
About prevention in line with the above, if the breeder is responsible and has all the controls done we still can not sing victory. It is very important that the puppy has a good diet according to his growth needs, which does not get fat (the image we all have of a rolly puppy is typical, but not healthy), supported by chondroprotectors if necessary, that the exercise is restrained (avoiding strange movements, and especially jumps and forced postures of the back three), be careful with the floors of the house (if they are slippery it is not a bad idea to get some old carpets that last us a few months).

Some exercises and “tricks” are very demanding with the hip, and therefore dangerous in puppies and young dogs.

And the greatest prevention: radiography There are many puppies that can limp for causes that have nothing to do with dysplasia, and in the same way, there are asymptomatic with serious femur and hip problems. The plate is painless, economical, and the only truly reliable method. At present we can know the state of the hips of our puppy from as early as three months (PennHip method), so that conservative treatments can be established, or in the case of an intervention being necessary, which is not drastic but reconstructive, preserving the joint. Until the year of age it is not possible to ensure that the hip has had a perfect development and, therefore, it will not be until then when the dog can start in canine sports (“start” is to go little by little) performing more demanding exercises with his body.

Elbow dysplasia in dogs

Elbow dysplasia is a very common degenerative disease in young dogs.

The elbow of dogs is one of the most congruent and stable joints of the body, allowing, due to its complexity, two axes of or degrees of supination-pronation movement of the forearm and flexion-extension. Its complexity is given by its composition: humeroradial joint, humeroulnar and, proximal radioulnar.

Elbow dysplasia was initially used to describe the non-union of the anconeal process (AUP). Currently, osteochondritis dissecans (OCD) of the medial condyle of the humerus, the fragment of the coronoid process (FPC) and, the incongruence of the elbow (INC) are also included within this term. When one of these ossification defects occurs in an elbow, inflammation originates and over time an osteoarthritis is triggered in which cartilage degeneration occurs; for that reason, all these conditions are commonly associated with osteoathrosis of this joint and are an important cause of pain and claudication of the forelimbs in large and giant breed dogs such as the German Shepherd, Labrador, St. Bernard, Rottweiler, Neapolitan Mastiff, among others.

Of multifactorial genetic origin, especially in OCD and FPC. It affects males more than females and can occur uni- or bilaterally. The genetic component is the one that has the greatest influence although, the appearance of this pathology can also occur due to food, weight, environment, quality of ligaments, a lot of physical exercise or trauma.

The first symptoms may occur at 4-5 months when the dog shows exercise intolerance, lameness when starting a movement or after prolonged exercise. There are dogs that do not show signs of affection in the elbow until advanced ages where the process of osteoarthritis is very evolved. Others manage to maintain a normal degree of activity throughout their lives.

The fact of making a premature radiological diagnosis makes it possible to establish an adequate treatment and avoids the formation of osteoarthritis that produces pain and functional limitation of the elbow throughout the life of the animal. The diagnosis can be complemented with diagnostic tests such as CT or MRI

The evolution depends on the degree and type of injury, but it is usually unfavorable without surgery. Surgical treatment is good if degenerative changes in the joint have not yet occurred. In any case it is necessary to perform a good rehabilitation in order to:

Speed up the recovery process
Eliminate pain and inflammation
Decrease lameness
Maintain and/or improve range of motion
Maintain muscle tone, mass and strength
Minimize or slow down the effects of joint degeneration – osteoarthritis
Avoid compensation at the level of the neck, spine and extremities
Give the maximum capacities so that the animal is functional and that it, with a good quality of life

Physiotherapy treatment varies depending on the animal and the state of the lesion. It is important to start as soon as possible with the treatment so that it is effective and, to avoid drying them as reduced mobility and / or chronic pain.

The animal goes through different phases until its full recovery. It is essential to gradually achieve the objectives set. The recovery process is terminated when the animal is able to perform daily activities.

During the first three days after the intervention, it is important to act on inflammation and pain and prevent muscle atrophy and decrease in the joint arch from appearing. For this, passive techniques are used that reduce inflammation, produce analgesia and help maintain tone, mass and the arc of mobility. Among these techniques there are electrotherapy (segmental TENS and muscle electrostimulation), massage, passive mobilizations and cryotherapy (cold).

In older dogs or dogs that have not been intervened, the objectives will be the same as in animals that have gone through an intervention. It is important to eliminate pain because, with pain you can not work.

It is important from the beginning to massage and move the affected elbow as long as there is no veterinary contraindication and, respecting in the case of fixation, the period of healing and union of the fixed parts. Massaging and moving the affected area and limb helps maintain mobility, prevents loss of mass and tone and works the proprioceptors.

A gentle mobilization combined with different massage techniques help decrease inflammation and reduce pain.

With TENSat the segmental level we can produce analgesia and decrease the amount of drugs administered. There are animals that have intolerance to certain drugs that produce analgesia and with TENS the pain can be reduced. TenS can also be used directly on the injured or operated area, as long as there is no osteosynthesis material underneath, since an internal burn could occur.

Muscle electrostimulationhelps prevent the onset of atrophy and maintain muscle mass and tone. With electrical stimuli we can stimulate nerve conduction.

At the beginning and end of the session the coldis used since it has properties that act on the decrease of the inflammatory response, edema and pain.

From the fourth day and during the next two weeks when the inflammation and pain have disappeared it is time to introduce simple active exercises such as shaking hands or small walks on a leash to force the animal to make an equal support with the four limbs and thus, prevent a decompensation between limbs from appearing due to not having a correct support on the ground. The walks is an exercise that increases the duration until full recovery.

Once the stitches have been removed, the animal can be introduced into the water. The advantages of water are used to improve recovery. Hydrotherapy (underwater treadmill) facilitates the station of the animal without loss of balance and, thanks to flotation, without having to support all its weight. In addition, flotation allows animals with bone pain and low muscle mass to work. The pressure of the water exerted on the body of the animal increases the sensitivity and decreases inflammations and edemas. The work in the water, underwater tapes or swimming increasesas the animal recovers. In addition, with water, we can recover the motor pattern, increase mass, tone and strength, work on respiratory capacity and maintain and / or improve mobility.

Once the acute phase has passed 48-72 hours and without risk of infection or inflammation, heat can be introduced that helps to elastify the tissues, decreases pain and increases vascularization among others.

The use of boards, plates, balls and trampolines are important to work on balance, proprioception and above all the integration of the affected limb.

It is already in the last phase, from two weeks, when the dog has integrated the gait pattern, exercises are performed to improve the quality of movement. They are more complex active exercises to integrate the affected limb or limbs. With active and proprioception exercises it is possible to increase muscle tone, mass and strength; coordination and balance and range of motion are worked on. Rails with different surfaces, cones, bars, circuits, up and down stairs and ramps (staircase with inclined plane) are used.

Throughout the recovery treatment and in animals with developed osteoarthritis it is essential to reduce the weight on the joints of the elbows. For this purpose , special support harnesses for elbows are used. In addition to decreasing weight, pain is reduced and does not hinder movement, the animal feels more comfortable; the joint is protected at all times from chafing and blows and helps maintain the heat that the animal gives off, which leads to a relief of the affected area.

At home, special care should be taken for animals suffering from elbow conditions. This care is necessary during and after treatment:

Avoid slippery floors
Avoid ramps and stairs at the beginning of treatment in operated animals and in animals that do conservative treatment. Once rehabilitated, ramps can be used to help get on the sofa and the car, since it is recommended that they do not do it alone, there could be a recidivism.
It is recommended that they rest on soft and clean surfaces, but that they are firm enough to help the incorporation of the animal special mattress for dogs
Keep skin clean and dry skin
Use special plates at your height so as not to strain the elbow joints
Correct diet and weight control. Being overweight harms the joints and generates more pain for the animal

It is very important to create an exercise routine and environment to help keep the animal comfortable and with quality of life.
