A method for implanting an intra-articular shoulder prosthesis is provided. The method includes removing a proximal portion of a humerus. The proximal portion of the humerus preferably forms a resected portion. The resected portion has a convex outer surface and an inner surface. The method further includes engaging the convex outer surface of the resected portion with a cut surface of the proximal portion of the humerus. The cut surface of the proximal portion of the humerus and / or the inner surface of the resected portion are optionally processed to form a generally concave surface, such as by impacting. In one embodiment, the inner surface of the resected portion is impacted into engagement with the cut surface of the proximal portion of the humerus. The generally concave inner surface of the resected portion forms a concave articular surface to receive an interpositional implant.

An articular disc prosthesis and method of implanting the same within an intervertebral space between adjacent vertebral bodies. The prosthesis includes a pair of articular components and an articular ball disposed therebetween. Each of the articular components includes an outer shell portion and a removable inner insert portion. The insert portion includes a concave articular surface sized and shaped to receive a portion of the articular ball to provide articulating motion between the articular components. The outer shell portion includes a central hemi-cylindrical portion, a pair of laterally extending flanges, and an axially extending lip. Following removal of the natural intervertebral disc, a pair of hemi-cylindrical recesses are formed along a central region of the adjacent vertebral bodies to a predetermined depth. The prosthesis is implanted within the prepared disc space by axially displacing the hemi-cylindrical central portions of the articular components along the hemi-cylindrical recesses in the vertebral bodies. The lateral flanges and the axial lip of the articular components bear against the endplates of the adjacent vertebral bodies to stabilize the prosthesis and to prevent subsidence.

A system and method used in total joint arthroplasty of a ball and socket joint such as hip and shoulder replacements for accurate positioning of a prosthesis through pinless surgical navigation during replacement surgery according to a predetermined distance from the center of rotation of the replaced joint and / or articular surface to obtain the proper length, offset, and biomechanics of the replaced joint.

An Extramedullary system of alignment for total knee arthroplasties uses a small diode laser at the center of the knee adjustable to the longitudinal axis of the femur to triangulate the center of the femoral head. It utilizes a V-Frame positioning device that fits into the distal femoral intercondylar notch and is tangent to the articular surfaces of the notch. It is also parallel to the anterior femoral cortex by using a removal tongue flange that sits flat on the filed surface of the anterior cortex. This prepositions the Distal Femoral Resector Guide within a few degrees of the center of the femoral head. An adjustment knob on the V-Frame pivots the distal femoral resector guide to the exact center of the femoral head for that particular patient accomplishing fine adjustment of the longitudinal axis of the femur. There is only one position where the laser beam will go through the center of the target no matter where you position the leg and that is when the target's bulls-eye is exactly over the rotational center of the femoral head. Since the laser confirms this position, the surgeon is assured that the alignment is accurate. The Distal Femoral Resector Guide is then fixed to bone with fixation pins and the resection made with a power saw. The laser is moved to the target mount to act as a longitudinal “laser ruler” for the remainder of the operation.

A prosthetic elbow for replacing an elbow of a dog or a human to restore normal, pain-free joint function. The elbow includes a humeral component for attachment to a humerus and a radioulnar component for attachment to an ulna. The humeral component includes a generally cylindric spool having a contoured external surface defining a first articular surface. The radioulnar component has a generally U-shaped contour with an inner peripheral surface defining a second articular surface sized and shaped for engagement with the first articular surface. Positional guides provide for implantation at precise locations.
