Total hip arthroplasty (THA) can eliminate pain caused by hip joint destruction and correct leg-length discrepancies (LLD). We present a short and simple intraoperative method for LLD correction in THA. We performed 55 primary THAs using this technique. The measurement error was 1.86 ± 1.4 mm, which was within 3 mm in 49 of 55 cases (89%) and within 5 mm in 54 of 55 cases (98%). This method is simple and does not require specialized devices, making it versatile to be used anywhere. No new skin incisions or extra costs are required, which will likely make it attractive to surgeons.
