Abstract
Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.
Claims18
A joint replacement prosthesis comprising:
- a base component;
- and
- two or more modular stems;
- wherein the base component comprises:
- a bone-facing surface including two or more stem connectors, wherein each stem connector is configured to receive and form a connection with one of the two or more modular stems configured to be inserted through a hole in a long bone from the bone-facing surface side, and wherein each of the two or more stem connectors has a longitudinal axis and the stem connectors are independently oriented at different angles with respect to the bone-facing surface so that their respective longitudinal axes are oriented at different angles;
- a lower surface that is opposite the bone-facing surface and lower with respect to the bone-facing surface;
- and
- an alignment feature provided on the lower surface for each of the two or more stem connectors, wherein each of the alignment features are coaxially aligned with the longitudinal axis of the two or more stem connectors such that each of the alignment features facilitate alignment of the two or modular stems with the two or more stem connectors.
