Abstract
A glenoid component includes an oval body having a concave lateral articulating surface and an opposing medial surface with a keel extending from the medial surface. The keel extends along a line which is anteriorly offset from the center line of the concave surface and is not collinear with any radius of the concave surface. New methods and tools are provided for the implantation of the glenoid component. Sizer drill guides are provided with an alignment arm which assures that the anterior/posterior angle of the pilot hole is approximately 65 degrees. An improved reamer tool is provided which allows the practitioner to attach a reamer head of selected size to the reamer rather than choosing among several reamers of different size at the time of the procedure. A new keel drill guide is provided which locates three drill guide holes in a plane which is offset approximately 2 mm anterior of the pilot hole. A new broach tool is provided for connecting the three holes and form a triangular or trapezoidal cavity for the keel. Methods for installing the glenoid component and using the tools are also disclosed.
