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 (176) 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.
