Abstract
A total hip arthroplasty system includes a medullary nail for insertion into a femoral canal of the femur, straight medullary nail with longitudinal axis, screw holes perpendicular to the longitudinal axis, and a hole having a transverse axis. The system also includes a bone anchor having a threaded opening for a cut-off femoral neck, a neck screw having a seat for the femoral head and a threaded shaft, a femoral head, and an acetabular cup assembly. A jig is provided for implanting the system and includes a guide that orients relative to the nail, attachment hardware, a rail adapted to extend parallel to the transverse axis of the nail, and a second guide slidably displaceable along the rail. The system provides significant adjustability and retains maximum bone for the possibility of revision.
