Orthopedic aids for dogs

injuries, most commented, Pathologies, Treatments, vet

New technical and orthopedic aids for dogs are used in a wide variety of cases. These increase the mobility of dogs by providing the necessary support to maintain daily activity. Dogs need to exercise to maintain their physical and emotional well-being. If a dog is unable to exercise, it can develop problems such as heart disease, obesity, bone alterations, muscle atrophy, and emotional problems such as aggression or anxiety.

Applicable cases

Technical aids can be used for sprains, muscle weakness, arthritis, hip dysplasia, post-operative rehabilitation, lameness, weakness or pain in the joints that end up generating a mobility problem. The technical aids should allow the dog to perform its daily activities, but they should also be comfortable and offer protection against irritations and ulcers on the dog’s skin so it is important that they are performed by specialists. We list the most frequent:

Knee

Knee protectors are typically used after surgery for rehabilitation of the anterior cruciate ligament (ACL), patella dislocation, medial collateral ligament (MCL), lateral collateral ligament (LCL), or posterior cruciate ligaments (PCL). Knee pads provide support and stability, prevent muscle loss during the recovery period, and reduce the risk of further injury. Knee protectors are also often used in cases where surgery is not performed.

Tarsus and Carpus

Tarsal protectors are indicated in cases of osteoarthritis but also for post-surgical rehabilitation or injury to the Achilles tendon, nerve damage to the hind limb or foot and rehabilitation of the hock joint. They can also be used as long-term support in non-surgical conditions. A tarsus or hock protector stabilizes the bone of the back leg, as well as the muscles and tendons of the limb and knee. It works similarly to a knee brace in humans, allowing the dog to move without straining the joint. It also prevents the dog from re-injuring the affected joint or ligaments.

Elbows

An elbow protector is used to support the elbow joint after surgery or to reduce pain from arthritis, degenerative joint diseases, or other similar conditions. It provides control in lateral movement while allowing for normal extension and flexion while treating and protecting hygromas and calluses.

Hip

A hip support holds and increases the temperature of the dog’s lower back and hip. Made of special neoprene, it surrounds the lower back, hip and upper leg and is fastened thanks to a Roman-type harness. Hip supports are commonly used for dogs with mild to moderate hip dysplasia and localized osteoarthritis.

Shoulders

Medial shoulder instability (MSI) is one of the causes of lameness in the front legs. A special support would allow the shoulder to be supported, which would limit the extension, flexion and abduction, allowing the dog to support its weight. These aids can be used after surgery or as a non-surgical treatment but also preventively.

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.

Paralyzed dog walks again after cell transplant

Curiosities, Treatments, vet

British scientists managed to reverse paralysis in dogs by injecting them with cells extracted from the lining of their own nose.

All of the animals in the study had suffered spinal cord injuries that prevented them from using their hind legs.

Researchers at the University of Cambridge, England, are cautiously optimistic that the technique may eventually play a role in treating human patients.

The study, funded by the Medical Research Council (MRC) and published in the neurology journal Brain, is the first to test transplantation in “real-life” wounds and not in laboratory animals.

Foreign scientists of the lining of the nose of animals are called olfactory enveloping glia (OEC) cells.

OLFACTORY ENVELOPING GLIA CELLS

The only part of the body where nerve fibers continue to grow in adults is in the olfactory system.

The enveloping cells of olfactory glia (OEC) are located at the back of the nasal cavity and surround the receptor neurons that allow us to smell and convert those signals in the brain.

Nerve cells need to be constantly replaced and this is promoted by the OCs.

For decades, scientists have weighed in that OECs could be useful in spinal cord repair. Initial trials with OEC in humans suggest that the procedure is safe.

These were cultured and reproduced for several weeks in the laboratory.

Of the 34 pet dogs that participated in the proof-of-concept trial, 23 received transplants of these cells at the site of injury and the rest received an injection with a neutral fluid.

Many of the dogs that had received the transplant showed considerable improvement and were able to walk on an exercise machine with the support of a harness.

None of the animals in the control group managed to reuse their hind legs.

Caution and optimism

The research was a collaboration between the MRC’s Centre for Regenerative Medicine and the University of Cambridge’s Veterinary School.

Professor Robin Franklin, a regenerative biologist at the STEM Cell Institute at the MRC and the Wellcome Trust and one of the report’s authors, said: “Our findings are extremely exciting because they show for the first time that transplanting these cell types into a severely damaged spinal cord can bring significant improvement.”

“We are hopeful that this technique can restore at least a small amount of movement in human patients with spinal cord injuries, but that is a far cry from the fact that they could recover all of their lost functions.”

Professor Franklin says the procedure could be used in conjunction with pharmacological treatments to promote nerve fibre regeneration and bioengineering to replace damaged neural networks.

The animals received a transplant of olfactory cells.

The researchers claim that the transplanted cells regenerated nerve fibers throughout the damaged region of the spinal cord.

This allowed the dogs to regain use of their hind legs and coordinate movements on their front legs.

But no new long-distance nerve connections like those required to connect the brain to the spinal cord were developed.

According to MRC scientists in humans this would be vital for a spinal cord injury patient who has lost sexual and bowel function and bladder control.

Professor Goeffrey Raisman, Chair of Neural Regeneration at the University of London, who discovered olfactory enveloping glia cells in 1985, says: “This is not a cure for spinal cord injuries in humans, which may still be a long way off.”

“This is not a cure for spinal cord injuries in humans, which may still be a long way off. But this is the most encouraging development in several years and is a significant step on the road to achieving it.”

Prof. Goeffrey Raisman

“But this is the most encouraging development in several years and is a significant step on the road to achieving it.”

“This procedure has allowed an injured dog to walk with its hind legs, but the range of much higher functions that are lost with a spinal injury, such as those of the hand, bladder function, temperature regulation, for example, are more complicated and still very distant.”

Jasper, a 10-year-old dachshund, is one of the animals that took part in the trial.

Owner May Hay told me that “before the treatment we had to transport Jasper in a car because his hind legs were useless. Now he walks all over the house and garden and can keep up with other dogs. It’s wonderful.”

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.
