One embodiment of the present disclosure provides a humeral implant. The humeral implant includes a tray including a body defining a bone facing recess and a liner recess, said bone facing recess including a ring surface and a convex surface, wherein the ring surface has a profile substantially corresponding to a profile of an outer ring of bone in an excision site of a patient; and wherein said convex surface has a profile substantially corresponding to a profile of a concave socket formed in the excision site. The humeral implant also includes a liner including a body defining a load bearing surface and a tray interface surface, said tray interface surface being configured to be at least partially received in said liner recess of said tray such that said implant is coupled to said tray.

An implant assembly may include a first component having a proximal plate and a distal portion extending from the proximal plate, a first screw of a first type, and a first screw of a second type. The proximal plate may have a proximal face, a distal face configured to abut bone, and a periphery. The proximal plate may define a plurality of apertures. An opening may be defined by the proximal plate and extend through the distal portion. Each of the plurality of apertures may be disposed between the opening and the periphery. The first screw of the first type may be sized and configured to be received in the opening and engage bone. The first screw of the second type may be sized and configured to be received in at least one of the plurality of apertures.

The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.

Prosthesis for a shoulder joint including a humeral component equipped with a stem, a head component and connection or articulation means of the humeral component with the head component, wherein the prosthesis according to the invention can be used both as a conventional prosthesis and as a reverse-type prosthesis.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

A humeral anchor assembly is provided that includes a humeral anchor and at least one screw. The humeral anchor is configured to form a part of or support a part of a shoulder prosthesis. The humeral anchor has a distal portion configured to be anchored in a proximal region of a humerus and a proximal portion. The proximal portion includes a proximal face configured to engage an articular component within a periphery thereof. The proximal portion also includes at least one aperture disposed adjacent to the periphery. The at least one screw is disposed through the at least one aperture. The screw has a first end portion engaged with the proximal portion of the anchor and a second end portion disposed in or through cortical bone of the humerus.

An expandable intervertebral spacer includes a body, a proximal end, and a distal end. The body includes quadrants that form a substantially cylindrical shape in a first configuration and a substantially cuboidal shape in a second configuration. Each quadrant includes a ramp portion with a ramp and a landing and a sliding portion with a sliding side and a foot. The ramp portion of a first quadrant engages the sliding portion of a second quadrant. The proximal end and the distal end couple with the plurality of quadrants and transfer an actuating force to expand the body from the first configuration to the second configuration.
