Complications and long-term outcomes after prosthetic capsule replacement in 15 dogs with traumatic hip luxation

Abstract

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.
