Hemiarthroplasty of the hip.

Hemiarthroplasty of the hip is a simplification of the Smith-Petersen cup arthroplasty in which half of the joint or femoral head is reshaped to fit the vitallium cup. This procedure shortens hospitalization to 10 to 14 days and has been successful in the relief of hip pain and in increasing hip motions. It is indicated when the disease is localized for the most part to the femoral head.
