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.

Humeral and glenoid articular surface implant systems and methods

The present disclosure provides an implant system. The implant system includes an anchor configured to be secured to bone within an excision site formed in a patient's glenoid, said anchor including a shank and an enlarged head. The implant system also includes a baseplate including a body comprising: a bone facing surface; an implant facing surface; and a channel configured to extend radially from an entrance in an outer periphery of said body to a central region of said baseplate, said channel configured to receive said enlarged head and a portion of said shank and including an open region formed, at least in part, in said bone facing surface. The implant system also includes an implant including a body defining a load bearing surface and a baseplate recess, said baseplate recess configured to receive at least a portion of said implant facing surface to said baseplate such that said implant is coupled to said baseplate.

Articular surface implant systems and methods including glenoid reverse shoulder

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.

Angled baseplate for humeral and glenoid articular surface implant systems and methods

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

System and method for repairing articular surfaces

Embodiments of devices, apparatuses, kits, and methods for repairing and/or augmenting the articular surface and/or articular rim of a joint (e.g., repairing the anterior glenoid rim after an anterior shoulder dislocation).

Devices, apparatuses, kits, and methods for repair of articular surface and/or articular rim

A method is provided for delivering an implant for replacing a portion of an articular surface. The method may include forming a socket in an articulating feature that is capable of moving relative to the articular surface. An implant may be placed in the socket and the articulating feature may be moved relative to the articular surface to generally align the socket with an implant site formed in the articular surface. The implant may be transferred from the socket into the implant site.

Articular surface implant and delivery system

A method according to one embodiment may provide access to an articular surface of a bone. The method includes forming a passage through at least a portion of the bone. The passage provides an opening in the articular surface. The method further includes inserting a tether through the passage. The tether inserted through the passage can be coupled to at least one device from an insertion site remote from the articular surface. The tether can be withdrawn through the passage to convey the device to a location proximate the articular surface.

Retrograde delivery of resurfacing devices

A system and method may be used for accessing an articular surface and for preparing an implant site on the articular surface. The method may include locating a portion of the articular. An access passage may be drilled towards the articular surface though bone behind the articular surface. An implant site may be excised in the articular surface relative to an axis defined by the access passage.
