CONICALLY-SHAPED GLENOID IMPLANT WITH A PROSTHETIC GLENOID INSERT USED IN TOTAL SHOULDER ARTHROPLASTY AND METHOD

摘要

A conically-shaped glenoid implant (1) having a fastening means for the acceptance of a conventional prosthetic glenoid insert (7) and a hole (9) located thereon for the acceptance of a locking means. The fastening means are preferably notches (ll)while the locking means is preferably reverse barbs (13). An optional screw (3) or keels (19) may be located on the exterior surface of the cone (2) for additional securement of the conically-shaped glenoid implant (1) in the glenoid (6) and to prevent rotation of the cone (27). By using the present invention, bone ingrowth is achieved because sheer forces are converted to compressive forces and surface area for ingrowth is significantly increased.
