Outcome of Canine Cementless Collared Stem Total Hip Replacement with Proximal Femoral Periprosthetic Cerclage Application: 184 Consecutive Cases

Introduction: The aim of the study is to report outcomes of cementless collared stem total hip replacement (THR) with proximal femoral periprosthetic cerclage application in dogs.

Materials and Methods: Serial postoperative radiographs and medical records of dogs (n = 150) that underwent cementless total hip replacement (THR) (n = 184) with a single full cerclage wire placed distal to the femoral neck osteotomy line and proximal to the lesser trochanter were reviewed for intra- and postoperative complications.

Results: No proximal femoral fractures occurred. No complications associated with the use of the cerclage wire were encountered. A fissure (n = 1) and fractures (n = 2) occurred near the tip of the femoral stem in three cases postoperatively. All three cases required plate and screw fixation. All dogs returned to subjectively normal function at home and all owners were satisfied with the outcome.

Discussion/Conclusion: A single full cerclage wire may minimize the risk of a proximal femur fracture following cementless collared stem total hip replacement in dogs. No complications with the cerclage wire were encountered. Application of a cerclage wire is a simple and economically feasible procedure that may decrease the risk of proximal femur fractures after cementless press-fit THR
