Abstract:
Objective To discuss the treatment of intraoperative periprosthetic fractures on the femoral side,and to evaluate the results of functional recovery after treatment.Methods Fifty-four cases of intraoperative periprosthetic fractures on the femoral side encountered from July 2002 to December 2006 were retrospectively studied.Fractures on the femoral side were classified by Mallory classification system.X-ray films were taken to evaluate the healing patterns of the fractures.Results Cerclage wires were adequate for stable type I and type Ⅱ fractures,while it could be treated expectantly when the fracture did not involve proximal femur in stable type Ⅱ.Unstable type Ⅱ fractures were taken care of with a long-stem uncementoid component.Type Ⅲ fractures were taken care of with a long-stem uncementoid component or LCP plate.Additional cortical strut allografts were used for the management of unstable fractures and the fractures with poor host bone stock.The average follow-up time was 23.5 months(5-52 months).All fractures were healed as shown by radiography except one case of type I fracture.There was no evidence of loosening or periprosthetic osteolysis on follow up radiograph.The mean postoperative Harris Hip Score was 94.5.Conclusion The treatment of intraoperative periprosthetic fracture around the femoral implant can successfully restore the function of the hip joint in most patients.Cerclage wires,long-stem uncementoid component and additional cortical strut allograft were effective treatment methods for different types of intraoperative periprosthetic fractures on the femoral side.Expectant treatment can achieve satisfactory result in stable type II fractures when the fracture did not destroy proximal femur.
