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 to increase the dogs quality of life. The dog will be reevaluated again prior to surgery in order to determine the continuing progression of the disease. A large portion of young dogs become less painful after the initial clinical signs subside when the joint capsule stabilizes. 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. There are other surgical options available. One treatment option would be to perform a triple pelvic osteotomy. Jocelyn is a borderline candidate for this procedure because she is slightly older than the ideal age of 6-8months and the presence of degenerative changes noted in the radiographs. These changes indicated that surgery would not alleviate symptoms and the progression of arthritis in this patient. Another treatment would be femoral head ostectomy. This procedure would eliminate any future pain, but may lead to future gait deficits. Total hip replacement is the recommended treatment plan for this patient/client combination if the lameness persists upon recheck in five months. Until the hip replacement surgery can be performed conservative management will be employed to keep the patient comfortable. 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 high impact exercise in order to keep inflammation to a minimum. We recommend swimming or walking up hills to maintain muscle tone without further damage to the hip joint. When the dog returns for reevaluation in five months complete physical exam and radiographs will be performed. If radiographic changes and symptoms persist the dog will undergo a total hip replacement of the right coxofemoral joint. 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.
