Abstract
Prosthetic systems, devices, and methods for attaching prosthetic joint components to a vault-shaped portion of the anatomy. A device for attaching a glenoid joint component for a shoulder prosthesis to a glenoid cavity includes a body adapted to extend into the cortical bony vault of the glenoid cavity for supporting the glenoid joint component and a plurality of contact arms secured to the body and projecting outwardly from a central longitudinal axis of the body to define contact surfaces for engaging an internal face of a peripheral wall of a glenoid vault.
Claims20
A surgical method of attaching a joint component to a socket in an anatomy, the method comprising:
- accessing the socket in the anatomy;
- introducing a support body into the socket such that a first end of the support body is positioned toward an open end of the socket, a second end of the support body is positioned toward a closed end of the socket, and the support body is spaced from a peripheral wall of the socket;
- pressing a plurality of contact arms against an internal face of the peripheral wall of the socket to secure the body in the socket, each of the plurality of contact arms being spaced apart from an adjacent one of the contact arms to form a plurality of passages about the body to the peripheral wall of the socket;
- and
- attaching a joint component to the first end of the body.
A surgical method of attaching a joint component to a socket in an anatomy, the method comprising:
- opening access to soft tissue surrounding a joint;
- removing bone to form the socket in the anatomy at the joint having an open end, a closed end, and a peripheral wall;
- positioning a support body having a plurality of spaced apart contact arms extending therefrom into the socket such that the plurality of contact arms engage the peripheral wall to secure the support body in the socket;
- and
- attaching a joint component to the support body.
A surgical method of attaching a joint component to a socket in an anatomy, the method comprising:
- forming the socket in a shoulder joint of the anatomy;
- pressing a plurality of spaced apart contact arms carrying a support body into the socket such that each contact arm engages an internal face of the socket to secure the support body in the socket;
- and
- attaching a shoulder joint component to the support body where the shoulder joint component includes either a concave or a convex articulating surface.
