Zusammenfassung:	Abstract A radial head assembly (100) is provided that includes a stem (124), a collar (108), a locking ring (I 12), and an articular member (I16). The stem has a convex articular head on one end thereof. The locking ring has a ring wall (220), which has a ring opening (224). The ring wall has an angular outer surface (228) and a slot (232) configured to permit the ring wall to radially expand. The angular outer surface engages an angular portion of an interior surface (172) of the collar. The articular member and the locking ring define an articular space (120) within the collar. The articular space is configured to receive the convex articular head.
