Abstract
Disclosed is a set of prosthetic components for use in shoulder replacements. A glenoid component having a base and a plurality of coupling members are disclosed. The coupling members are used to couple the base to at least one of the acromion or coracoid process. A polymer insert which is configured to couple to the base member and articulate with a humeral component is provided.
Claims15
A method of implanting an implant comprising:
- preparing a glenoid surface;
- coupling a glenoid base having a generally L-shaped cross-section formed of a superior ledge portion and support tray, to the prepared glenoid surface;
- at least one of translating or rotating the glenoid base to engage the superior ledge portion with at least one of the acromion or coracoid process, after coupling a glenoid base to the prepared glenoid surface;
- measuring a distance between the superior ledge portion and at least one of the acromion or coracoid process;
- placing a spacer defining an aperture between the superior ledge portion and at least one of an acromion or coracoid process of a patient;
- coupling the spacer to the glenoid base;
- coupling the glenoid base to the spacer and to at least one of an acromion or coracoid process by passing a fastener through the aperture and into the bone and
- after coupling a glenoid base to the prepared glenoid surface, fixing a bearing component having a generally L-shaped cross-section having a bearing superior ledge and a concave ledge articulating surface to the glenoid base so as to couple the bearing superior ledge to the superior ledge portion.
