Abstract
A short main incision and portal incisions at portal positions strategically displaced from the main incision are provided in a patient's hip. One portal incision (acetabular portal) provides for a disposition of reamers in the patient's acetabulum to shape the acetabulum. A cannula is inserted through the portal incision to the acetabulum and the successive reamers of progressive size are inserted into the acetabulum through the main incision to progressively size and shape the acetabulum. An approximately hemispherical acetabular component is then disposed in the prepared acetabulum to provide for hip rotation relative to the femoral component. The other portal incision (femoral portal) provides for insertion into the patient's hip of a member for driving the femoral stem into a cavity in the patient's femur. The provision of the short main incision and the portal incision minimizes the patient's loss of blood, tissue trauma, length of operating time and patient recovery time.
