Bone preparation tool kit and associated method

摘要

A humeral prosthesis includes a first body having a first body articulating surface defining a generally circular outer periphery, and a first centerline axis. The first body having a support surface opposite to the first body articulating surface, the first body is hollow and configured to receive a head of the humerus, and a stem extending away from the support surface, the stem defining a second centerline axis which is coincident with the first centerline axis. The prosthesis further includes a second body in the form of a flange which extends laterally from a portion of the circular outer periphery, the first body articulating surface and a surface of the second body defining a boundary portion between them which is generally smooth and continuous, wherein the second body is located superiorly and the surface of the second body which bounds the first body articulating surface is a second articulating surface.

主权项

1. A humeral prosthesis for fitting to a humerus in a shoulder joint arthroplasty procedure, the prosthesis comprising:
a first body having a first body articulating surface defining a generally circular outer periphery and a first centerline axis, the first body having (a) a support surface opposite to the first body articulating surface such that the first body is hollow and configured to receive a head of the humerus, and (b) a stem extending away from the support surface configured to assist in securing the prosthesis on the humerus, the stem defining a second centerline axis which is coincident with the first centerline axis; and a second body in the form of a flange which extends laterally from a portion of the circular outer periphery of the first body articulating surface, in which the first body articulating surface and a surface of the second body define a boundary portion between them which is generally smooth and continuous, wherein the second body is located superiorly and the surface of the second body which bounds the first body articulating surface is a second articulating surface.
