Abstract
Disclosed are prosthesis systems and methods that provide porous fixation rings by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.

A method of performing a reversible anatomic shoulder replacement procedure, comprising:
- reaming a cavity into the glenoid;
- and
- inserting a fixation ring and an anatomic glenoid articular implant into a glenoid cavity, the fixation ring comprising:
- an outer diameter, the outer diameter substantially similar to a diameter of a lateral peripheral edge of the anatomic glenoid articular implant;
- a superior surface configured to abut a medial surface of the anatomic glenoid articular implant,
- wherein the fixation ring is configured to circumscribe a medial peripheral edge of the anatomic glenoid articular implant, and
- wherein the fixation ring is configured to be at least partially implanted within the glenoid cavity.
A reversible anatomic shoulder replacement system, comprising:
- an anatomic glenoid articular implant;
- a fixation ring configured to be positioned within the glenoid cavity, the fixation ring comprising:
- an outer diameter, the outer diameter substantially similar to a diameter of a lateral peripheral edge of the anatomic glenoid articular implant;
- a superior surface configured to abut a medial surface of the anatomic glenoid articular implant,
- wherein the fixation ring is configured to circumscribe a medial peripheral edge of the anatomic glenoid articular implant, and
- wherein the fixation ring is configured to be at least partially implanted within the glenoid cavity.
- to be at least partially implanted within the glenoid cavity.
