Summary

The investigators aim to demonstrate the ability to accurately measure and restore leg length, offset, and center of rotation during a total hip replacement through a new technique that uses the femoral component as a measurement tool. The operative technique 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 pre-arthroplasty measurements of leg length and offset are recorded. The femoral neck osteotomy is performed, and the native femoral head is removed and measured. The acetabular socket is prepared and the acetabular component is inserted. A repeat measurement with trial modular neck components is taken and allows the surgeon an additional opportunity to accurately recreate leg length and offset with the final component. The reference screw is removed from the ilium and the incision is closed.
