A Vertical Measurement System to Predict the Change in Leg Length in Total Hip Arthroplasty
The management of leg lengths in total hip arthroplasty continues to challenge orthopaedic surgeons. The aim of this study is to test the reliability of a measuring device used to measure the resected femoral head and how the resulting intra operatively calculated change in leg length compares to th...
