Objective To evaluate the clinic effects of THA in failed internal fixation of hip fracture.Methods 30 patients treated from June 2012 to June 2016 were retrospectively analyzed to evaluate the curative effects of total hip arthroplasty.There were 21 patients with failed internal fixation of femoral neck fracture，6 with failed fixation of intertrochanteric fracture，3 with failed fixation of acetabular fracture.Results All of the 30 patients underwent a successful operation and no complication occurred.The mean operation time was (85±22)mins.The patientswere followed up for 15.7 months (10～24 months).The average Harris Hip Score was improved from 68.5(range：52～78) preoperative to 92.6(range：85～96) postoperative.The good and excellent rate was 86.7％.There were no prosthesis loosening，sinking and dislocation at final follow-up.Conclusion Total hip arthroplasty is a effective，safetreatment option for failed internal fixation of hip fracture.It can recover the hip joint function and alleviate the hip pain.At the same time，it can lessen those complications resulted from the joint dysfunction and improvethe lifequalitiesof patients.
