An anchor for securing an implant within bone. In one embodiment, the anchor is used to aid in securing an acetabular cup within an acetabulum. The anchor may be implanted within an ischial defect of the pelvis, and is attached to an outer surface of the acetabular cup shell. The anchor is made at least in part of, and may be made entirely of, a porous metal material to facilitate the ingrowth of surrounding bone into the anchor for osseointegrating the anchor into the surrounding bone. The anchor may be secured to the acetabular shell by a screw fastener or by cement, for example. The anchor may be secured to the acetabular shell before the anchor and the acetabular shell are together implanted into the acetabulum, or the anchor may be implanted into the ischial defect, followed by seating the acetabular shell in the acetabulum and then securing the acetabular shell to the anchor.

Implant anchoring device

A hip stem prosthesis is provided for treating a deficient hip joint.

Hip stem prosthesis

An apparatus for removal of a femoral implant may include a handle portion and a cutting blade opposite the handle portion. The cutting blade may include a cutting edge, wherein the cutting edge includes a non-linear shape to substantially match at least a portion of a profile of the femoral implant to be removed.

Femoral explant device

A hip prosthesis is provided for insertion into a femur. In one exemplary embodiment, the hip prosthesis includes a stem having a proximal end, a distal end, and a longitudinal axis. This stem may include anterior and posterior locking surfaces which diverge away from the longitudinal axis. A shank portion may extend distally from the anterior and posterior locking surfaces and converge at an angle distally toward the longitudinal axis.
