A prosthetic glenoid component for attachment to a glenoid surface of a scapula to replace a natural socket of a shoulder and to provide a bearing surface for a head portion of an arm bone or humerus. The glenoid component has a metal back with integrally formed attachment legs which are cemented into corresponding holes formed in the glenoid surface, and also has an opening for receiving a hollow metal cage which is screwed into the glenoid surface.

A graft harness for securing a ligament in a bone tunnel takes the form of a shaped plug having a proximal end and a distal end. A radial groove is formed in the distal end of the plug which accepts a looped ligament graft. A suture passageway formed through the plug transverse to the groove accepts a length of suture. The proximal end of the plug features a concave configuration adapted to accept the distal end of an interference screw. A ligament graft is secured in a bone tunnel using the graft harness by seating the looped graft within the groove to form a harness/graft construct, passing a length of suture through the suture passageway, and drawing the harness/graft construct into the tunnel using the length of suture looped through the suture passageway. The graft is secured primarily using an interference screw which engages the concave proximal end of the harness. The harness provides secondary fixation of the graft in the bone tunnel.

A modular endoprosthetic radial head implant includes an end cap secured to a cannulated body held to bone by a fixation element. The fixation element supports the cannulated body on a resected radial bone end, for example. The fixation element of one embodiment features a threaded stem with a spherical head. The stem fits distally into the cannulated body and extends through a hole formed by the distal end of the cannulated body. The spherical head nests inside the cannulated body. Polyaxial alignment between the cannulated body and the fixation element is locked using a jam nut tightened inside the cannulated body. An end cap fits into place proximally on the cannulated body. The end cap is formed of a joint surface material to provide a bearing surface.

Glenoid prosthesis with a hybrid design (combining both peg and keel designs), and surgical methods for reconstitution of a shoulder joint. The hybrid design combines both peg and keel components into one device. The hybrid glenoid component of a shoulder prosthesis includes an oval body having a concave lateral articulating surface and an opposing convex medial surface. The medial surface is provided with a plurality of pegs and a single inferior protrusion. The pegs are used to attain both a superior location as well as a central location. The inferior protrusion provides stability in the superior-to-inferior translation of the humeral head, as well as rotational articulation of the same.

A parallel drill guide and system which maintains contact on the bone at various angles. The parallel drill guide comprises a fixed sleeve and a parallel, axially slidable, sleeve for guiding the insertion of two parallel wires or pins into bone at any angle while maintaining contact between the bone and the guide. The drill guide is also provided with a locking mechanism that locks the slidable sleeve into position at any lateral distance relative to the fixed sleeve, using a novel off-axis locking device.

A humeral prosthesis includes a stem component and a head component joined by an inclination component. The inclination component is provided with an opening that is designed to accommodate a pair of expandable tabs extending from a side of a plate. The plate is also provided with a taper extending opposite to the pair of expandable tabs. Inclination angle, radial offset, and version are adjustable and are separately and independently set and fixed.

An elongated cannula with an inner tube that is designed to cooperate with a corresponding outer tube. The cannula may include a cam mechanism, a plurality of flexible members designed to expand and deploy when the inner and outer tubes move relative to each other, and a pressure ring disposed on the outer tube. The inner and outer tubes are slidably moveable relative to each other in at least one direction.

An articulating hook elevator for manipulating tissue during arthroscopic procedures. The articulating hook elevator comprises a shaft, a proximal end, and a distal end provided with an articulating paddle. The hook may be actuated by a switch and can articulate into a standard tip for traditional manipulation of tissue, or into a rotated or articulated position. In this manner, effective manipulation and retraction of tissue from the surgical site without tissue collapse may be achieved, allowing a surgeon to better visualize the internal condition of the arthroscopic site and speed up the overall procedure.
