Overview
Osteochondritis dissecans (OCD), also known as joint flap disease, is a joint condition where a piece of cartilage becomes detached from the bone. This detachment leads to pain and lameness in affected dogs. OCD is prevalent in large and extra-large breed dogs during their growth phases. The severity of OCD can range from mild discomfort to severe pain and lameness. If left untreated, it may lead to arthritis.
Causes
The primary cause of OCD is abnormal cartilage development in the joints, often because of rapid growth in young dogs. This abnormality can cause the cartilage to become loose and detached.
Secondary causes contributing to OCD include genetic predispositions, nutritional imbalances, and trauma to the joints. These factors can exacerbate the condition, leading to more severe symptoms.
Additionally, hormonal imbalances and excessive physical activity during a dog’s growth period can further contribute to the development of OCD.
Predisposed Breeds
Breeds predisposed to osteochondritis dissecans include:
Symptoms
Primary symptoms of OCD include lameness, joint pain, and reluctance to exercise or bear weight on the affected limb. These symptoms are usually the first indicators of OCD.
Secondary symptoms may involve swelling of the affected joint and a decrease in the range of motion. These symptoms can progress as the condition worsens.
Other symptoms can include muscle atrophy in the affected limb and audible clicking sounds from the joint. These signs suggest more advanced OCD stages.
Osteochondritis dissecans symptoms include:
- Lameness
- Joint pain
- Reluctance to exercise
- Swelling of joint
- Decreased range of motion
- Muscle atrophy
- Clicking sounds from joint
Diagnosis
Diagnosis of OCD typically involves a veterinarian conducting a physical examination and obtaining X-rays. These steps help assess the condition of the joint and detect any loose cartilage fragments.
Advanced imaging tests, such as MRI or CT scans, may be used for a more detailed evaluation of the joint. These tests can provide a clearer picture of the extent of the damage.
OCD should be differentiated from other conditions, like elbow dysplasia, panosteitis, and hypertrophic osteodystrophy. Correct diagnosis is essential for effective treatment.
Treatment
Treatment options for OCD may include surgical intervention to remove loose cartilage fragments. Surgery can alleviate pain and restore joint function.
Non-surgical approaches, such as weight management, physical therapy, and medications, can also help manage pain and inflammation. These treatments support joint health and prevent further deterioration.
Management
Long-term management of OCD involves maintaining a healthy weight and providing joint supplements. These steps help support joint health and reduce stress on affected joints.
Regular, low-affect exercise is important for dogs with OCD. This type of exercise can help maintain mobility without exacerbating the condition.
Prevention
Prevention strategies for OCD focus on proper nutrition during a dog’s growth phase. A balanced diet can support healthy cartilage development and reduce the risk of OCD.
Avoiding excessive exercise in young dogs is also important in preventing OCD. Overexertion during growth phases can contribute to joint issues.
