Complications and long-term clinical outcomes for 15 dogs surgically treated for traumatic craniodorsal hip luxation by prosthetic capsule replacement (PCR) with a prosthetic ligament were retrospectively reviewed. A PCR technique with capsulorrhaphy was performed in all dogs using acetabular screws with washers and a femoral tunnel as anchor points for the polyester prosthetic ligament. A non–weight-bearing sling was not placed. Minimum 1 yr follow-up period was required for study inclusion. Two major complications (13.3%) consisting of craniodorsal hip reluxation (n = 1) and capital physeal fracture (n = 1) were observed. Minor complications (superficial skin necrosis) occurred in one case (6.7 %). The patient with craniodorsal hip reluxation underwent femoral head and neck ostectomy and was excluded from long-term analysis. In the 11 cases that returned for long-term (median, 3.8 yr; range, 19–75 mo) evaluation at the authors’ institution, 10/11 of the dogs were clinically sound. Three dogs did not return for long-term evaluation. However, telephone interview with owners minimum1 yr after surgery indicated normal limb function and absence of complications in all three cases. These results suggest that PCR with polyester prosthetic ligament can be successful in maintaining hip reduction in dogs with craniodorsal hip luxation.

Prosthetic capsule replacement (PCR) is an extra-articular surgical technique for treatment of craniodorsal hip luxation (CHL) in dogs. Three reports have documented short-term outcomes of PCR used to treat CHL in dogs with successful outcomes in 65-67% of cases. Objectives of this study were to describe a modification of the original surgical technique without a greater trochanteric osteotomy or non-weight-bearing sling in dogs with traumatic CHL. MethodsData were collected minimum 1-year postoperatively. A modified PCR technique was performed without non-weight-bearing-sling postoperatively. A synthetic polyester suture was placed in a figureof-eight pattern between a bone tunnel in the femoral neck and two bicortical screws with washers in the dorsal acetabular rim. Shortterm (4-10-weeks postoperatively) and long-term (>1-year postoperatively) clinical and radiographic rechecks were performed at the authors' institution. Descriptive statistics were calculated. ResultsFifteen dogs met the inclusion criteria. Median body weight was 22.4kg (range, 6.1-68). One major complication (6.7%; hip reluxation) was recorded in short-term recheck (median 42 days) in a dog with moderate hip dysplasia.
