Abstract: A modular humeral prosthesis for replacement of the humeral head of a humerus. The prosthesis generally comprises a stem to be fitted to a resected humerus; a head sized and configured to approximate the humeral head; and an intermediate connecting member for connecting the stem to the head. The intermediate connecting member provides a desired angle of inclination or offset between stem and head. The head may be a traditional humeral head, or it may be an eccentric humeral head, with its mating portion being offset. The head may also comprise a groove or milled trench at least partially surrounding or otherwise defining mating portion. Also disclosed is a modular humeral prosthesis kit comprising a variety of different intermediate connecting members that may be selected to fit the prosthesis to the patient, and a method of replacing a humeral head in a patient.

Abstract: Methods, systems, and devices for replacement of a joint with a prosthetic system that replicates the natural kinematics of the joint is disclosed.

Abstract: Artificial implants having reduced area to provide reduced wear are provided. The reduced area is particularly located at areas where greatest wear is exhibited. In a particular embodiment of a mobile bearing knee implant, the area is reduced on the mobile bearing insert underside, where it contacts a tibial component. The reduced area may be any shape of indentations, for example, grooves, dimples, straight patterns, curved patterns, crossing patterns, holes, channels or slots. The indentations may be various sizes, and have been found to be particularly effective if covering about 10% to about 20% of the insert at depths between about 1-2 mm.

Abstract: Polymeric medical fixation screws with multiple cannulations and thereby a reduced risk of shearing while being torqued into place are provided. The polymeric screws have at least two cannulae, on either side of a central longitudinal axis of the screw, extending parallel to the longitudinal axis. Torquing instruments are inserted into the cannulae so that the applied torque force for driving the screws into a bone hole is distributed along the shaft of the screw. In one embodiment, the invention provides interference screws, while in other embodiments the invention provides medical fixation screws with heads and soft tissue-to-bone anchors or suture anchors. The polymeric screws may be fabricated from virtually any suitable biocompatible polymers or composites, including bioabsorbable polymers and their composites.

Abstract: An angled bone fixation apparatus including a bone screw having a first end portion adapted to be surgically implantable into a patient's vertebral bone mass and at first and second spaced apart positions on the bone mass and a second end portion having a head portion with a load transfer surface thereon and a top surface. An elongated plate member having upper and lower surfaces angled with respect to each other and an elongated plate slot having a longitudinally extending axis with the slot being surrounded by a peripheral portion having outer opposed edges. The plate member has a first and second angled sidewall at the slot with the sidewalls each forming an acute angle with the upper and lower plate surfaces. A washer interfaces with the plate member and the bone screw, for distributing load from the bone screw to the plate member with the washer including an opening and upper and lower surfaces with the lower surface having a pair of spaced apart projections extending therefrom.
