Abstract: A radial head assembly is provided that includes a collar, an articular member, an articular head component, and stem that is configured to engage the articular head component. The articular member at least partially defines an articular space within the collar when disposed in the collar.

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.
