Hemiarthroplasty: The Procedure
During a hip hemiarthroplasty, an incision is made over the outside of the hip. The fractured ball (femoral head) is removed and replaced with an implant. In a normal hip replacement surgery, the socket of the pelvis would also be replaced. This can be done in patients with pre-existing arthritis of the hip, but in most cases of femoral neck fractures the socket is left alone. The prosthetic stem can be cemented into the bone in patients with thinner, more osteoporotic bone, or press-fit into patients with better bone quality.
