Abstract

Canine hip dysplasia is a very common medical condition in large breed dogs which can cause severe limitations in activity and lifestyle. Hip joint denervation is a new procedure for the treatment of pain related to dysplasia and the resulting arthritis. The goal of the procedure is to provide a pain-free joint, allowing normal activity despite arthritis. This proposed study would assess the long term results and success rates after surgery. The denervation would be performed on the worst hip in clinically affected dogs. These dogs would be assessed at 1 and 3 months to evaluate improvement. Improvement would be measured using a combination of subjective and objective techniques. Subjectively, the dogs would be evaluated via physical examination and scoring of the degree of lameness. Objectively, the amount of weight bearing would be measured using a force plate as the dog was walked across a platform. Force plating is useful as it can quantify weight bearing. Abnormalities can be detected even in dogs who are not visibly lame at the time of evaluation on force plate. This measurement would allow comparison between the two hindlimbs over the course of the study, as well as change over time in the use of the treated limb after surgery.
