Abstract: A radial head assembly is provided that includes a stem, a collar, a locking ring, and an articular member. The stem has a convex articular head on one end thereof. The locking ring has a ring wall, which has a ring opening. The ring wall has an angular outer surface and a slot configured to permit the ring wall to radially expand. The angular outer surface engages an angular portion of an interior surface of the collar. The articular member and the locking ring define an articular space within the collar. The articular space is configured to receive the convex articular head.

Abstract: Provided is a glenoid implant for a shoulder prosthesis that includes: a baseplate including a proximal end, a distal end, an outer periphery, and one or more recesses that extend therethrough adjacent to the outer periphery and extending from the proximal end to the distal end; an internal member disposed in each of the one or more recesses, the internal member defining an aperture extending from the proximal end to the distal end through the internal member; and a screw for each of the at least one internal member, the screw configured to be placed through the aperture, the screw having an external threaded surface. The internal threaded surface of the internal member has more thread starts than the external threaded surface of the screw.
