Abstract: A system for guiding a glenoid prosthesis is disclosed. The system includes a glenoid guide that includes: a guide feature; at least three arms having a first end coupled with the guide feature and a second end disposed away from the guide feature; at least three peripheral pegs, each peripheral peg extending from the second end of a corresponding arm and includes an engagement surface configured to engage the scapula of the patient; and a strut extending laterally from the guide feature.

Abstract: An apparatus and modeling method of the present invention includes the successive steps of generating cartographic data representative of points belonging to a glenoid surface; distinguishing from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first surface part being situated farthest down in the vertical direction in relation to the scapula; calculating from the first group of cartographic data a first ellipsoid portion that coincides substantially with the first surface part; and obtaining a theoretical glenoid surface from the first ellipsoid portion. By virtue of the theoretical glenoid surface obtained by this method, it is possible to assist the surgeon in optimizing the position of implantation of a glenoid component and to produce a glenoid component “made to measure” for the scapula that is to be fitted with a prosthesis.

Abstract: A method of guiding a glenoid prosthesis is disclosed. The method includes pre-operatively determining a position and an orientation of a guide feature of a glenoid guide of the present disclosure based on a scapula of a specific patient, and engaging the glenoid guide with the scapula; and inserting a pin having an axis through the guide feature to or through the scapula.

Abstract: A patient specific glenoid guide is provided to facilitate properly aligned implantation of a glenoid prosthesis into a patient. The guide shape is designed preoperatively based on the unique configuration of the scapula of the patient. The guide orientation is chosen preoperatively based on one or more of the bone structure of the patient, the wear pattern of the patient's glenoid cavity, the anchoring means of the glenoid prosthesis, or other aspects.

Abstract: In one embodiment, a humeral implant is provided that includes a hollow stem and a mounting end. The hollow stem has a sharp distal edge. The mounting end has a mounting hole and a mounting channel disposed about the mounting hole. The mounting hole is configured to receive a tapered projection of an anatomic articular body. The mounting channel is configured to receive an annular projection of a reverse articular body.

Abstract: A glenoid bone augment component is provided that includes a first side, a second side, and a body that extends between the first side and the second side. The first side is configured to be disposed away from a glenoid of a patient. The second side is configured to be placed on the glenoid. The body is configured to adjust the spacing from the glenoid of a prosthesis component coupled with the first side when the second side of the glenoid bone augment component is coupled with the glenoid. The body has one or both of a central channel and a plurality of peripheral anchor channels disposed therethrough. The channels can be configured to receive a tool for forming an opening in the glenoid. A peripheral reinforcement structure is disposed around at least one of the peripheral anchor channels of the plurality of peripheral anchor channels and/or a central reinforcement structure is disposed around the central channel.
