Causes and Signs of Osteochondrosis

Osteochondrosis (OCD) occurs commonly in the shoulders of immature, large and giant-breed dogs. The lesion appears on the caudal surface of the humeral head (Figure 1). Although your dog may be lame in only one leg, this condition is often present in the opposite leg. This condition results in a cartilage flap found on the humeral head. In some cases, the resulting defect occupies half of the area of the humeral head. The cartilage flap may completely detach from the underlying bone and become lodged in the back of the joint pouch.

Causes
The causes of OCD considered to be multifactorial with input from management, genetic and nutritional interactions in young growing dogs.

Incidence and Prevalence
Large and giant-breed dogs are commonly affected. Males are more commonly affected than females.

Signs and Symptoms
Clinical signs often develop when the dog is between 4 and 8 months of age. Dogs usually show a lameness of one forelimb. In many cases, there is a gradual onset of lameness that improves after rest and worsens after exercise.

Risk Factors
Risk factors for OCD include age, gender, breed (genetic), rapid growth, and nutrient excesses, primarily calcium excesses. The hereditary nature is suggested because of high frequency of occurrence within certain breeds of dogs and within certain bloodlines. Males are more commonly affected than females.

When to Seek Veterinary Advice
If your young large breed dog is persistently lame in a forelimb, especially after exercise, you should have a physical exam performed. If the dog is painful on palpation of the shoulder, usually during shoulder extension and flexion, then radiographs of the shoulder should be made to evaluate for OCD.
