Abstract
Disclosed are embodiments of anatomic glenoid implants that incorporate hybrid fixation.
Claims21
A glenoid implant, comprising:
- an articular body formed of a polymer material and comprising:
- an articulation surface and a medial surface on an opposite side of the articular body from the articulation surface;
- and
- a hybrid fixation post extending distally from the medial surface of the articular body, wherein the hybrid fixation post comprises a hybrid composition that includes:
- a base portion that is an extension of the articular body;
- and
- a distal portion comprising a metallic structure, wherein the base portion and the distal portion are joined in a manner in which an interface is formed between the base portion and a proximal end of the distal portion,
- wherein the interface comprises an interlocked structure comprising the polymer material and the metallic structure.

A method of forming a glenoid implant, comprising:
- forming distal portion of a hybrid fixation post including a metallic structure;forming an articular body comprising:
- an articulation surface, a medial surface on an opposite side of the articular body from the articulation surface, and a base portion of the hybrid fixation post extending distally from the medial surface, wherein the articular body comprises a polymer material, wherein the base portion and the distal portion of the hybrid fixation post are joined in a manner in which an interface is formed between the base portion and the distal portion, and wherein the interface comprises an interlocked structure comprising the polymer material and the metallic structure.
