An expandable vertebral body device, system, instrument, and methods of assembly and using the device, system, and instrument are disclosed. The vertebral body device includes a body with a first end and a second end, a first rotating member rotatably coupled to the first end, a second rotating member rotatably coupled to the second end, a first extension member moveably coupled to the first end, and a second extension member moveably coupled to the second end. The expandable cage system comprises a vertebral body device and an insertion instrument. Methods for assembling and using the vertebral body device and instrument are also disclosed.

An implant preshaped before placement anteriorly between a superior endplate and an inferior endplate within a void created by a transcorporeal procedure in a vertebra, the implant having no circular cross-sectional dimension.

Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.

Modular bone reinforcement systems, bone plates, assembled bone reinforcements, and methods of reinforcing a bone are described. A modular bone reinforcement system includes a plurality of bone plates, each of which has a series of tabs disposed along at least one edge of the bone plate for forming a snap-fit attachment to a mating series of tabs of another bone plate of the plurality of bone plates to form an assembled bone reinforcement. A first bone plate of the plurality of bone plates has a first shape and a second bone plate of the plurality of bone plates has a second shape that is different from the first shape. The modular bone reinforcement system can include additional components, such one or more fixation devices, reduction devices, navigation aids, or other components.

A surgical or arthroscopic method for resurfacing at least one surface of a hip joint of a human patient, using a medical device comprising an artificial hip joint surface, wherein the hip joint surface comprising an acetabulum surface and a caput femur surface, said method comprising the steps of: creating at least one hole passing into the hip joint, dissecting and preparing the hip joint, introducing at least one artificial hip joint surface, comprising at least one of an artificial acetabulum surface and an artificial caput femur surface, wherein said at least one artificial hip joint surface, comprising a first sealing member, creating a sealed hollow space between said first sealing member and one of the acetabulum surface or said artificial acetabulum surface and one of the caput femur surface or said artificial caput femur surface, selecting at least one artificial hip joint surface and injecting a material into said hollow space.

The present disclosure relates to a system and method for repairing an articular surface. A guide pin may be secured to an articular surface of a glenoid, wherein the guide pin defines a working axis and the working axis is positioned at an angle α relative to the articular surface, wherein angle α is less than or equal to 90 degrees. An excision device may be advanced over the guide pin, wherein the excision device includes a cannulated shaft and at least one cutter, wherein the at least one cutter is generally aligned in a single plane. A generally hemi-spherical excision site may be formed with the excision device within the articular surface of the glenoid.

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.

An expandable vertebral body device, system, instrument, and methods of assembly and using the device, system, and instrument are disclosed. The vertebral body device includes a body with a first end and a second end, a first rotating member rotatably coupled to the first end, a second rotating member rotatably coupled to the second end, a first extension member moveably coupled to the first end, and a second extension member moveably coupled to the second end. The expandable cage system comprises a vertebral body device and an insertion instrument. Methods for assembling and using the vertebral body device and instrument are also disclosed.

An implant assembly including an expandable vertebral body replacement implant. Two outer cores disposed on opposing ends of an inner are configured to move away from each other when the inner core is actuated. The implant assembly may include removable endplate configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant may include a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism may be automatically engage after removal of an inserter instrument from the implant assembly.
