An intraoperative device to restore femoral offset in total hip arthroplasty.

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.
