Patent ID: 7374576

Claim:
A method of surgically repairing a hip joint, the method comprising: providing a femoral hip prosthesis comprising a femoral head component and a femoral stem component; the femoral stem component comprising a neck portion with a proximal male friction fit portion and a distal neck body, a flange portion distal and adjacent to the neck portion attached to the distal neck body having an upper portion and a bottom surface, a transitional body region, adjacent to the bottom surface of the flange portion and extending from the distal neck body, an elongated stem portion, extending distally from the transitional body region and aligned with an longitudinal axis that is aligned at an acute angle from the bottom surface of the flange portion; resecting the bone tissue on the proximal femur to form a resected proximal femur; preparing a non-eccentric, symmetric intramedullary cavity in the proximal femur, wherein the intramedullary cavity is straight along its entire length; reaming a boss cavity in the proximal femur; inserting a portion of the elongated stem portion of the femoral hip prosthesis in the intramedullary cavity; inserting at least a portion of a rotation-restricting boss into the boss cavity; and placing at least part of the flange portion on the resected proximal femur.
