Abstract: A stemless humeral anchor (10) includes a first end (12) configured to be embedded in a proximal portion of a humerus and a second end (14); a mating portion (16) for an articular component; a transversely extending collar (20); and a rotation control feature (22, 22A) for resisting rotation when the stemless humeral anchor is implanted. A void filling protrusion (24) can extend circumferentially from rotation control feature and can include a porous shell (26), in which a void filling component (28) can be disposed. The rotation control feature can comprise arms. One or more arms (22A) can have a larger radial extent than the others (22). A prosthesis assembly includes a base member (104) that has a helical structure (224) and one or more pathways (300). The pathway is accessible from a proximal end and is directed distally through the helical structure. The pathway is located inward of an outer periphery of the helical structure. The pathway extends in a space between successive portions of the helical structure. The prosthesis assembly includes a locking device (108) that has a support member (132) and an arm (110) that projects away from the support member. The arm is disposed in the pathway when the support member is disposed adjacent to the proximal end of the base member. The arm is disposed through bone in the space between successive portions of the helical structure when the prosthesis assembly is implanted.

Abstract: An inserter includes a first end, a second end, and a body extending between the first end and the second end. A first impacting surface is disposed at the first end, and a second impacting surface is disposed adjacent to the second end. An interface disposed at the second end and is configured to engage an implant. The first impacting surface is configured to direct a first impacting force along the body of the inserter in a first direction, and the second impacting surface is configured to direct a second impacting force along the body in a second direction that is different from the first direction. Methods of use also are disclosed.
