Abstract
A substantially cup-shaped prosthetic device for a joint is provided. The prosthetic device includes an outer surface configured to operatively engage at least one of a first bone of the joint and a component and an inner surface configured to connect to a second bone of the joint. The inner surface is rotationally asymmetric to minimize intrusion on a vascular region of the second bone.
Claims12
A substantially cup-shaped prosthetic device for a joint, comprising:
- an outer surface configured to operatively engage at least one of a first bone of the joint and a component;
- and
- an inner surface configured to engage a second bone of the joint,
- wherein the inner surface is rotationally asymmetric such that an arc along the inner surface in a plane perpendicular to a longitudinal axis of the inner surface has a non-constant radius of curvature, and
- wherein the prosthetic device is a femoral head cup.
