A novel and improved elbow prosthesis and method of implanting same including a prosthesis system that has a retaining system. The joint prosthesis system can include an implant, and an alignment guide. The alignment guide can include a post member extending through a central axis of rotation in a prosthesis and a drill guide member having a first limiting member for limiting articular surface removal from a joint. The first limiting member can include a recessed guide for positioning the implant.

Milling apparatus for implanting a joint prosthesis

A novel and improved elbow prosthesis and method of implanting same including a novel aggregate prosthesis having a retaining system in conjunction with a set plate.

A bone plate has a curved elongated body including a first end portion and a second end portion. The first end portion is laterally offset relative to the second end portion, and includes a plurality of screw holes. A first screw hole is defined by the second end portion. Each of the screw holes of the first end portion are laterally offset from a straight line extending in a direction along a length dimension of the bone plate and bisecting the first screw hole of the second end portion, and each of the screw holes of the first end portion are on the same side of the straight line as one another.

Osteotomy plate for long bones

A novel and improved retaining member can be used with a joint prosthesis which may be implanted with a minimally invasive surgical technique. The retaining member can be configured to releasably link together two or more components of a joint implant in an orientation suitable for implantation. The retaining member can be removed once the joint implant has been positioned within the implant site.

Methods for implanting a joint prosthesis

An interarticular ligament prosthesis is formed from a plurality of high strength high modulus polymeric fibers. The fibers are independent and free from intrinsic inter-fiber shear coupling found in braided or bonded fibers. The ligament prosthesis is installed with tubular, bone screw anchors. The fibers of the ligament prosthesis pass through the central hole of the anchors and are knotted at one end. The exit holes of the anchors include ceramic eyelets with polished edges. The edges are rounded to a defined radius for desired fatigue life of the prosthesis.

ACL prosthesis and anchor therefor

Disclosed are embodiments of an improved joint prosthesis that can provide the option to improve initial stability without removing the implant or altering the preparation. Embodiments of improved joint implant components can comprise one or more expandable, hollow segmented posts. Methods of implant fixation are also disclosed. Disclosed methods can provide the opportunity for establishing initial biologic fixation (bone ingrowth), and can also provide an adjunct fixation through injecting cement down the center of the post if initial stability is not achieved or is questionable.

Joint implant fixation system

A method of implanting an aggregate joint prosthesis with a side approach to a joint includes exposing a side surface of a joint and positioning a pin member within the joint. Articular surfaces can be drilled and milled, and the prosthesis can be implanted. A set plate can be removed, with the set plate being configured to releasably link at least two components of the aggregate prosthesis.

A novel and improved canine elbow prosthesis and method of implanting same including a unique bi-compartmental prosthesis having bone receiving members and transverse pegs which may be implanted with a minimally invasive surgical technique.
