Abstract:
1. A method of performing a surgical procedure to replace the humeral head of a patient's humerus, comprising: resecting the humeral head of the patient's humerus so as to create a generally planar resected humeral surface, securing a sizing instrument to the resected humeral surface, the sizing instrument having a number of punch guide holes formed therein, advancing a surgical punch through the punch guide holes formed in the sizing instrument to create a number of punched holes in the resected humeral surface, and implanting a stemless humeral component into the resected humeral surface such that a number of cantilevered legs of the stemless humeral component are positioned in the punched holes formed in the resected humeral surface, wherein implanting the stemless humeral component comprises: (i) securing the stemless humeral component to an implant insertion tool, (ii) positioning the implant insertion tool such that the ends of the cantilevered legs of the stemless humeral component are advanced into the punched holes formed in the resected humeral surface, and (iii) impacting the implant insertion tool to drive the cantilevered legs of the stemless humeral component into the punched holes formed in the resected humeral surface, wherein securing the stemless humeral component to the implant insertion tool comprises: (i) inserting a number of alignment keys of the implant insertion tool into a number of viewing windows of the stemless humeral component, and (ii) threading a locking rod of the implant insertion tool into a threaded bore of the stemless humeral component.
