Abstract: A shoulder prosthesis of the present invention includes a modular humeral prosthesis component employing a collarless design. A body portion of the prosthesis is provided without a collar, and it may be implanted into a prepared proximal end of a humerus such that the body sits recessed below the level of the cut proximal surface of the humerus. A head portion is provided in which a support surface of the head functions as collar by direct apposition of it to the cut proximal humerus. The modular connection is thus recessed below the proximal bone surface. By providing a modular connection which is recessed below the bone surface, the benefits of modularity may be retained, while joint overstuffing may be reduced or eliminated, and a substantially full range of motion may be achieved.

The method further includes looping a first end portion of a second band around the retaining member such that both the first end portion of the second band and a second end portion of the second band extend outwardly from the retaining member. Moreover, the method includes securing the soft tissue to (i) the first end portion and the second end portion of the first band, and (ii) the first end portion and the second end portion of the second band.

Abstract: In one embodiment of the invention, a method is provided including the steps of preparing an opening in the bone sized to receive a prosthesis therein and then inserting an apertured temporary implant into the opening. A fluent material is then injected into the temporary implant so that the material exudes from the apertures into contact with the bone surrounding the temporary implant. The temporary implant is then removed to make way for implanting the prosthesis into the bone opening. The fluent material can be a biological, biocompatible or bioactive material, such as a composition adapted to permanently fill voids and irregularities in the bone or a composition adapted to promote bone growth. In another embodiment, an implant assembly includes an apertured sleeve adapted to be permanently implanted within the bone opening, but providing apertures for injecting a fluent material into the opening.

The reamer is thus flexible with respect to the interconnection between the individual segments.

Abstract: A tibial trial assembly for evaluating the stability and kinematics of a tibial implant, particularly a mobile bearing implant, prior to committing to the final preparation of the proximal tibia is described. The tibial trail assembly includes a tray trial adapted to be secured onto a resected proximal end of a patient's tibia.

Preferably, the evaluation bullet is removable from the trial tray such that the remaining assembly is used to locate and guide (orient) the instrument(s) that prepare the tibia for the final implant. Typically, this includes broaching, drilling, or punching through the opening in the trial tray/plate.
