Abstract: A glenoid prosthesis includes a head portion and an anchor. The head portion includes a first surface adapted to contact a glenoid and an opposed second surface that is at least partially concave. The anchor extends from the first surface of the head portion and terminates at a distal end. At least one first circular member is disposed between the head portion and the distal end of the anchor and encircle the anchor. At least one second circular member is disposed between the head portion and the distal end of the anchor and encircles the anchor. The at least one first circular member is adapted to engage cortical bone of a glenoid and the at least one second circular member is adapted to engage cancellous bone of a glenoid when the glenoid prosthesis is implanted.

Abstract: Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

Abstract: An instrument to insert a humeral anchor includes a handle including a shaft extending from a first end to a second end; a manual grip at the first end configured to rotate the shaft; and a humeral anchor grip at the second end, wherein the handle is configured to actuate the humeral anchor grip between a first configuration to apply a radially outward force to an interior surface of the humeral anchor and a second configuration to separate the humeral anchor grip from the interior surface of the humeral anchor.

Abstract: A shoulder assembly is provided which includes a base member including a collar; a helical structure extending from the collar in a distal direction; and a first pathway projecting distally of the collar and through the helical structure adjacent to an inner periphery thereof, the first pathway being generally transverse to the helical structure and extending in a space between successive portions of the helical structure; and a locking device comprising a proximal support and a first arm projecting distally of the proximal support, the first arm configured to be disposed in the first pathway projecting distally of the collar when the proximal support is disposed adjacent to the collar; where the first arm is disposed through bone in the space between successive portions of the helical structure when the shoulder assembly is implanted.

Abstract: A glenosphere handling tool, which can be an impactor, 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.
