A technique of acetabular reconstruction for uncemented total hip replacement.
A technique for performing uncemented total hip replacement in the presence of osteoarthritis with proximal femoral migration is detailed. The femoral head is used as an autograft. The center of rotation of the hip is returned to its anatomic location, and subchondral bone is preserved. Rigid fixation of the graft is accomplished with matching reamers and AO lag screw fixation. Simultaneous reaming of graft and host bone produces a seamless transition to ensure graft loading. The goals of restoration of anatomic hip center, rigid press fit, and complete cup coverage are accomplished.
