Elbow Dysplasia in Dogs: treatment, causes, symptoms, video and type

Elbow dysplasia is a genetic condition that affects the elbow joint of dogs, primarily larger breeds such as Golden Retrievers, German Shepherds, and Labrador Retrievers. It occurs when the three bones that make up the elbow joint do not develop properly and do not fit together correctly, causing abnormal wear and tear on the joint. This can lead to pain, stiffness, and eventually arthritis.

Signs of elbow dysplasia in dogs can include limping, reluctance to walk or play, and stiffness after exercise. The condition can be diagnosed through X-rays and other imaging tests. Treatments may include medication to control pain and inflammation, physical therapy, and surgery to correct the joint abnormalities.

If you are considering getting a dog, it is important to research the breed’s potential genetic health issues, including elbow dysplasia, and to purchase from a reputable breeder who screens their breeding dogs for the condition. Additionally, maintaining a healthy weight and providing regular exercise can help prevent excessive strain on the joints and potentially reduce the risk of developing elbow dysplasia.

Symptoms of Elbow Dysplasia in Dogs

Symptoms of elbow dysplasia can appear as early as 4 months of age or later in puppyhood. Some dogs don’t show any signs of the disorder until they are older or even geriatric. Generally, the more severe the abnormality in the elbow, the earlier the symptoms will appear.

Symptoms

• Signs of pain upon bending or straightening the affected joints
• Intermittent or persistent lameness that is made worse by exercise
• Difficulty in getting up from a reclining position
• Swollen elbows
• Reluctance to play or go on walks
• Decreased range of motion of one or both elbows
• Elbows held at an odd angle
• Crackling or crunching sounds from the elbow when the dog flexes or extends it

Generally, dogs with elbow dysplasia will limp when walking or trotting—you’ll often observe the dog’s head bobbing up and down as it walks—but the limp disappears when the dog is running. Pain can make the dog reluctant to play or even go for a walk.

A dog suffering from elbow dysplasia can have a marked decrease in range of motion in the joint and will often display signs of pain or discomfort upon extension or flexion of the elbow. It may hold the affected limb away from the body and may have intermittent or persistent lameness that is made worse by exercise but can also be observed as stiffness when first getting up after resting.1

If they are geriatric, it is common to see sudden episodes of lameness in the limb. As the condition progresses, there may also be fluid buildup in the joint and a grating of bone-on-bone can be apparent as the cartilage continues to wear away.2

Causes of Elbow Dysplasia

There are three bones that make up the elbow joint: the radius, ulna, and humerus. Four separate skeletal conditions relating to the elbow can result in the overall condition of elbow dysplasia. One or more can be present at the same time.

• Ununited Anconeal Process: a growth plate does not close properly, leading to a detached piece of bone that can cause joint irritation and degeneration
• Fragmented Coronoid Process: a piece of bone breaks off inside the elbow joint, irritating the lining of the joint and causes the cartilage to wear away
• Osteochondrosis Dissecans: a piece of cartilage loosens from the surface of the joint, resulting in pain and inflammation
• Elbow Incongruency: the structure of the joint itself is imperfect, causing the cartilage to wear away more rapidly

How Do Vets Diagnose Elbow Dysplasia in Dogs

If you suspect your dog is suffering from elbow dysplasia, make an appointment with your veterinarian. Your vet will obtain a history along with a general physical exam and in-depth orthopedic exam, which will include observations of your dog’s gait and radiographs (x-rays).

Radiographs will help better visualize the joint and can show open growth plates, conformational abnormalities, and any bony fragments that may be causing irritation. If the radiographs are questionable, your vet may want to send them off to a veterinary radiologist for interpretation. Veterinary radiologists are board-certified in reading radiographs, as well as other images such as ultrasound, MRI, and CT scans. These specialists will be better able to identify more subtle changes in the joint space brought on by elbow dysplasia.

Occasionally more advanced testing may be required for a definitive diagnosis. This may include getting an MRI and/or using a needle to aspirate a sample of fluid from the joint space. The joint fluid obtained can then be tested for inflammation or infection that could further complicate your dog’s condition.

How to Treat Elbow Dysplasia in Dogs

Treatment options depend on the severity of your dog’s condition. If the elbow dysplasia is mild, conservative medical options may be offered. Management of mild-to-moderate symptoms can often be accomplished through non-steroidal anti-inflammatory drugs. Joint supplements such as glucosamine/chondroitin (e.g., Dasuquin, Cosequin, Vetri-Flex, Glycoflex) and essential fatty acid supplements may also help to lubricate the joint and decrease inflammation.3 Integrative therapies such as cold-therapy laser can also help decrease pain and inflammation.

If your dog’s condition is more severe, there are some surgical options. The most common is using a fiberoptic scope (called arthroscopy) to enter the joint space and clean out any loose flaps or pieces of cartilage and/or bone. On rarer cases, a board-certified surgeon may opt for an open-joint approach instead of the arthroscopic method.

After surgery, or if your dog has a moderate case of dysplasia, your vet may refer you to a certified canine rehabilitation practitioner for physical therapy activities, such as swimming, walking on an underwater treadmill, and range of motion exercises.

Healthy exercise is of the utmost importance in dogs with elbow dysplasia. It may seem counter-intuitive to exercise a joint that is arthritic but balancing out the right amount and the right kind of exercise can prevent muscle atrophy as well as weight gain. Atrophied muscles and extra pounds can exacerbate arthritis.4 Check with your vet to see what type of exercise would be best for your dog.

Prognosis for Dogs with Elbow Dysplasia

Your dog’s individual prognosis will depend on its age, overall health, and the severity of the joint. However, most dogs with elbow dysplasia respond well to pain-relieving therapies or necessary surgeries and go on to live healthy, happy lives.

How to Prevent Elbow Dysplasia in Dogs

Because it’s an inherited condition, elbow dysplasia cannot usually be prevented other than by not breeding dogs that have the abnormality. However, early detection can enable vets to begin treatment before the condition seriously impacts your dog’s quality of life.
