Abstract: A proximal femoral ball assembly having a variable offset that is selectively adjustable to conform to various anatomical conditions encountered during a femoral surgical procedure. The femoral ball assembly generally includes a head, a neck, and an adjustment mechanism. The head has a smooth spherical outer surface that is adapted to engage an acetabular component or native acetabulum. The neck extends outward from the head and removeably connects to the head using a threaded attachment.

Abstract: A proximal femoral head assembly having a variable offset that is selectively adjustable to conform to various anatomical conditions encountered during a femoral surgical procedure. The assembly includes a femoral head, a neck removeably connectable to the femoral head, and an adjustment mechanism. The adjustment mechanism provides the neck with a plurality of different femoral offsets with respect to a femoral hip stem.

Abstract: The present invention is directed to a radiolucent aiming guide for locating and drilling through the holes in the distal end of an implanted intramedullary nail. The aiming guide comprises an elongate handle constructed substantially of a radiolucent material, which does not cast a strong image on a monitor when exposed to radiation. The radiolucent handle is used in conjunction with a protection sleeve, trocar, drill sleeve, and drill bit, which are used to locate and drill through the hole in the nail. Radiopaque components in the distal end of the protection sleeve, trocar, and drill bit are used to align the drill over the nail hole. A pair of radiopaque pins, located within the handle and lying parallel to its longitudinal axis, aid in ensuring the proper rotational alignment of the aiming guide over the nail hole. The aiming guide may also include a structure to facilitate its alignment over a second hole in the distal end of the intramedullary nail.

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.
