Abstract: A humeral trial and implant assembly for use in total shoulder arthroplasty is provided along with a method for using the same. The humeral trial and implant assembly includes a humeral fixation component, an adapter assembly, a humeral trial, a humeral implant, and a positioning guide. The humeral trial is coupled to the adapter assembly when the humeral trial and implant assembly is assembled in a trialing configuration. The humeral implant is coupled to the adapter assembly when the humeral trial and implant assembly is assembled in an installed configuration. A temporary connection releasably couples the humeral trial to the adapter assembly and provides separation of the humeral trial and the adapter assembly without requiring disassembly of the adapter assembly. A permanent connection fixedly couples the humeral implant to the adapter assembly. The temporary connection may be a magnetic connection.

Abstract: A method for implanting a reverse modular humeral implant into a humerus that includes a natural humeral shaft and a natural humeral head. The implant includes a humeral stem implantable into the natural humeral shaft, and an adapter couplable to the humeral stem, the adapter including an anchoring projection configured to be coupled to a convex bearing.

Abstract: A bone reamer includes a first member having a first hub and a second member having a second hub. The first hub can extend along a first axis and have a pair of elongated cutting arms that are fixed to the first hub. The elongated cutting arms can extend along a second axis that is generally perpendicular relative to the first axis. The first hub can define a track thereon. The second hub can extend along a third axis. The second member can have a second pair of elongated cutting arms that are fixed to the second hub and extend along a fourth axis that is generally perpendicular to the third axis. The second member can have a track follower extending thereon and that is configured to slidably advance along the track causing the first and second members to move between a collapsed position and an expanded position.

Abstract: A humeral cut guide system for a humeral head comprises: a bone-engagement member including a first patient-specific bone-engagement surface that is complementary and made to substantially mate and nest in only one position on a specific patient's humeral head; a registration member connected to the bone-engagement member including a second patient-specific bone engagement surface that is sized and made to substantially mate and nest in only one position with the specific patient's bicipital groove; a first protrusion extending from the registration member and having a first surgeon-engaging surface for manipulation by a surgeon; and a cut guide plate connected to and extending away from the registration member such that, upon the bone-engagement member mating and nesting with the specific patient's humeral head, the cut guide plate is spaced apart from the humeral head, wherein the cut guide plate defines an elongate slot.
