Abstract: A humeral implant configured for implantation at a distal end portion of a humerus. The humeral implant can be configured to articulate with a portion of an ulna. The humeral implant may include a body portion having a first end, a second end, and a side surface that extends between the first end and the second end, where the side surface includes a concave region that defines a first cross-sectional diameter that is a minimum cross-sectional diameter of the body portion.

Abstract: A glenosphere handling tool, which can be an inserter, is provided that includes an elongate body and a retention portion. The retention portion is disposed at a distal end of the elongate body. The retention portion includes a plurality of wall segments of the elongate body separated from each other by one or more slots. The slot(s) extends proximally from the distal end of the elongate body. The retention portion also includes an enlarged periphery at the distal end of the elongate body. The enlarged periphery comprising a proximally facing edge configured to engage an inner wall surface of a glenosphere. The retention portion is configured such that when the retention portion is in a free state the proximally facing edge faces and may contact a surface of a glenosphere to retain the glenosphere. The retention portion is configured to be deflected at the distal end of the elongate body such that the enlarged periphery has a reduced profile for separating the handling tool from a glenosphere.

Abstract: An ulnar implant configured for implantation at an end portion of an ulna. The ulnar implant may be configured to articulate with a portion of a humerus, which may be a native end surface of the humerus bone or a humeral implant. The ulnar implant may have a curved or saddle shaped member. The curved or saddle shaped member may include a first concave surface and a second convex surface.

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.
