  • Collapsible acetabular reamer
    Patent number: 7097646
    Abstract: A method and apparatus for performing minimally invasive hip surgery to implant an acetabular shell into the acetabulum. A collapsible acetabular reamer is moveable between an expanded position and a collapsed position. In the expanded position, the reamer reams the acetabulum. In the collapsed position, the reamer can fit through a small minimally invasive incision.

  • Elongated driving bit attachable to a driving instrument and method of use for minimally invasive hip surgery
    Patent number: 6875218
    Abstract: A method and apparatus for performing minimally invasive hip surgery for implanting a prosthetic acetabular component into a natural acetabulum. The method and apparatus include a driving bit having one end connectable to an angled driving instrument and another end connectable to a screw-hole plug, dome plug, or bone screw. The driving bit has an elongated body with a length adapted for use in minimally invasive acetabular surgery.

  • Eccentric neck for femoral hip prosthesis
    Publication number: 20040138757
    Abstract: An implantable femoral hip stem having an offset neck extending outwardly from the proximal region of the stem. The neck has two parallel axes that are separated by an offset distance. A first axis is concentric with the distal end of the neck, and a second axis is concentric with the proximal end of the neck. Together, the two axes form an eccentric neck.
