An intraoperative device to restore femoral offset in total hip arthroplasty (Journal of Orthopaedic Surgery and Research)

Background: Leg length discrepancy (LLD) after total hip arthroplasty (THA) can lead to unsatisfactory outcome. Our objective was to design and evaluate a simple and reliable intraoperative device (Length-offset Lever) to minimize leg length discrepancy. Methods: This device was used in 51 patients undergoing primary total hip replacements. The leg length discrepancy was measured pre- and postoperatively based on plain radiographs. Results: Preoperative radiographic leg length discrepancy averaged 13.5???6.2 mm. Leg length discrepancy showed significant improvement, with a postoperative average of 4.1???2.3 mm (p?
