Management Plan: The best outcome will be provided by performing a complete hip replacement which can't be performed until the dog has matured at 12-14 months. In the meantime the goal is to mange the dogs pain and inflammation and to include the dogs quality of life. The dog will be reevaluated again prior to surgery in order to determine the continuing progression of the disease. Some dogs become less painful after the microfractures of the acetabulum heal. If lamesness persists it is due to degenerative changes of the joint and surgery is required. An appointment will be made for a total hip replacement of the right hip. The animal will then be evaluated for a period of six months postsurgically to determine if lameness persists in the left limb. If this is the case, we will also perform a total hip replacement on the left hip. It is important to note that if any infectious process is present at the date of the surgery that the surgery cannot be performed due to the high risk of contamination of the surgical site. This problem will be addressed if needed and the surgery rescheduled. Another treatment option would be to perform a triple pelvic osteotomy. However, this procedure would not be recommended for this patient since this patient is slightly older than the ideal age interval (6-8 months) for this surgery. The presence of degenerative changes on the radiograph would indicate that this surgery would not successfully alleviate lameness in this patient. Until the hip replacement surgery can be performed the dog will be placed on the antiinflammatory, Etogesic (1 300mg tablet PO QD). We will also give Adequan, a polysulfated gycosaminoglycan for its possible chondroprotective effects., This will be given IM 1 mg/kg once every 4 days for 6 doses and repeated as needed every 6 weeks. These medications may help alleviate pain but may not relieve all symptoms. We will also recommend that the dog no longer be fed free choice in an attempt to eliminate excessive nutrient intake. The dog should also be restricted from exercise in order to keep inflammation to a minimum. Postsurgical care will include oral cephalexin (30 mg/kg PO BID) for three days. The dog should be kept in close confinement with limited leash exercise for one month postsurgery. The dog should return for a checkup at 4 weeks to evaluate range of motion and pain. If this evaluation is favorable then the animal will be allowed to return to normal activity. It may take up to 6 months for muscle atrophy to resolve and for complete function to return. At this point in time the left hip will be evaluated.
