ABSTRACT:
A proximal femoral prosthesis minimizes impingement, thereby affording an enhanced range of motion as compared to existing devices. The central portion of the neck of a prosthesis according to the invention is oriented distally relative to a straight line drawn between the ball portion and a point of interconnection to the exposed portion of the stem. Such a configuration reduces impingement in flexion/internal rotation and extension/external rotation, assuming an appropriately placed acetabular component. In the preferred embodiment, the neck is curved between the head and the neck. In alternative embodiments, the neck may be provided in straight and/or modular segments. The invention is compatible with neck-shaft angles, offsets, head sizes, and other dimensions commonly designated with respect to available implants.
