The operative technique for measuring leg length requires inserting the femoral component prior to performing the femoral neck osteotomy. After the femoral component is implanted, a reference guide is attached to the femoral component and guides a screw into the ilium at a fixed distance from the femoral component. The first measurements of leg length and offset are recorded. The reference guide is removed from the femoral component and the femoral neck osteotomy is performed. The native femoral head is removed and measured. The acetabulum is prepared and the acetabular component is inserted. A repeat measurement with trial components in place allows the surgeon an additional opportunity to accurately recreate leg length and offset with the final component. After the final components are inserted, the reference screw is removed from the ilium and the incision is closed. All total hips in this study will be performed through a superior approach so that the anterior and posterior capsules are preserved and hip stability is maximized. This capsular tissue preservation approach will prevent or at least limit the need to deliberately lengthen the leg in order to gain hip stability.
