Femoral neck osteotomy guide for total hip arthroplasty . BACKGROUND Total hip arthroplasty ( THA ) is a common last-resort treatment for hip disease , but postoperative patients often complain of discrepancies in leg length . This study introduces a device designed to increase the precision of the femoral neck osteotomy and reduce the incidence of leg length discrepancy . METHODS Forty-eight patients undergoing THA were divided into two groups , with and without the use of the femoral osteotomy guide . All operations were performed through a posterolateral approach . Differences in leg length were recorded before and after the operation . Measurements were also made to compare the preoperative plan with the actual amount of bone removed . RESULTS The mean average difference in femoral neck resection height was 0.84 mm when using the osteotomy guide and 1.69 mm without the guide . Discrepancies in postoperative leg length were 5.45 mm and 13.37 mm in the groups with and without the guide , respectively . CONCLUSION The femoral neck osteotomy guide is an effectively auxiliary tool for increasing the accuracy of bone resection in arthroplasty using the posterolateral approach .
