Abstract
A glenoid component includes a body, a first, convex surface, a second, concave surface, a third surface connecting the first and second surfaces, a channel, and at least one alignment member. The channel extends from a first channel opening of the first surface through the body to a second channel opening defined on the third surface and has a channel axis extending through the first and second channel openings. The channel axis intersects a first plane defined by the first channel opening at an angle transverse to the first plane. The channel is configured to receive a bone engagement member to attach the body to a shoulder bone. The at least one alignment member extends from the first surface to align the body to the shoulder bone. The bone engagement member can attach the body to the shoulder bone.
Claims20
A glenoid component for use in a shoulder prosthesis, comprising:
- a body including a first surface that is convex and a second surface opposite the first surface, the second surface is concave;
- a third surface connecting the first surface to the second surface;
- a channel extending from a first channel opening of the first surface through the body to a second channel opening defined on the third surface, the channel having a channel axis extending through the first channel opening and the second channel opening, the channel axis intersecting a first plane defined by the first channel opening at an angle transverse to the first plane;
- at least one alignment member extending from the first surface to align the body to a shoulder bone, the at least one alignment member including at least one of a substantially peg shaped projection, a substantially cylindrical shaped projection, or a substantially conical shaped projection;
- and
- a bone engagement member to attach the body to the shoulder bone, the bone engagement member to occupy at least a portion of the channel wherein the channel is configured to receive the bone engagement member to attach the body to the shoulder bone;
- wherein the third surface defines a first tangent line tangent to the third surface adjacent to the second channel opening and a second tangent line tangent to the third surface on an opposite side of the third surface from the second channel opening;
- wherein a first angle is defined between a second plane perpendicular to the first tangent line, and the first surface where the third surface meets the first surface and a second angle defined between a third plane perpendicular to the second tangent line, and the first surface where the third plane meets the first surface, the second angle greater than the first angle, the at least one alignment member extending from the first surface at a point closer to the second angle than the first angle.
