The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Systems and tools for inserting and securing an implant within the intervertebral space. An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. The implant may be provided with various securing members for fixing the implant within the intervertebral space. A tool may be used to insert the implant, which includes a plurality of shiftable implant engaging members that are shiftable between non-engaging and engaging configurations to alternatively release or hold the implant.

A spinal implant comprises a body including a first vertebral engaging surface and a second vertebral engaging surface. At least one of the surfaces includes at least one tissue penetrating member. The at least one member includes a cutting surface and a guide surface that defines a cavity configured for disposal of tissue. Systems and methods of use are disclosed.

A method includes generating a surgical plan for aligning a structure with a first bone segment and a second bone segment, and controlling a controllable guide structure to guide a cutting tool to sculpt the first bone segment, the second bone segment, and the structure based on the surgical plan. The method can include providing the first bone segment with a first bone mating surface by sculpting the first bone segment, providing the second bone segment with a second bone mating surface by sculpting the second bone segment, and providing, by sculpting the structure, the structure with at least one structure mating surface that is complementary to at least one of the first bone mating surface or the second bone mating surface.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body having a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear ends. The front and rear ends extend in a transverse direction and a central axis of the body extends from the rear end to the front end. The rear end defines a first fastener hole having a first central axis and a second fastener hole having a second central axis. The first and second central axes extend parallel to one another at an acute angle relative to the body central axis in the transverse direction.

Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include frames and one or more endplates coupled to the frame. The frame may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws or anchors, and secure the implant to the adjacent vertebrae.

Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include a spacer and one or more inserts or members coupled to the spacer. The inserts or members may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws, and secure the implant to the adjacent vertebrae.

A joint implant assembly including a spherical shaped component adapted to securing to an end of a first joint defining bone and a recess shaped component adapted to securing to an end of a second joint defining bone. Each of the components establishes an opposing wear surface, at which microscopic sized particles build up over time resulting from prolonged use of the joint. At least one of the spherical and recess shaped components exhibits a plurality of interior entrapment chambers, each of which including a narrow-most entranceway location communicating with the wear surface. The entrapment chambers further exhibit outwardly widening capture profiles extending within the associated component for securing volumes of the microscopic particles away from a zone defined between the wear surfaces.
