Abstract: 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 (11) 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.

Abstract: A prosthetic humeral device (1) having at least two guide holes (11) located at predetermined locations thereon for the acceptance of a fastening means (29), which is preferably a screw (16) and a predeterminedly-shaped washer (6) with at least one projection (17) located on the underside. After inserting the elongated stem (14) of the prosthetic humeral device (1) into the humerus (2), a tuberosity grasping tool (19) is used to grasp a tuberosity (4) and (7). The tuberosity (4) and (7) is then positioned to an appropriate level on the prosthetic humeral device (1), a hole is drilled into the tuberosity (4) and (7), the screw (16) with washer (6) is inserted, the grasping tool (19) is removed and the screw (16) and washer (6) are tightened.
