Combination Reamer/Drill Bit for Shoulder Arthoplasty

An instrumentation kit for use in preparing a shoulder to receive a glenoid component comprising:

• at least one combination device, the combination device including
• a boring section configured to rotationally form a first bore in a glenoid of a shoulder,
• a drive section operably connected to the boring section and configured to receive a rotational force,
• a reaming section positioned proximally from the boring section and operably connected to the drive section, the reaming section configured to rotationally ream a portion of the glenoid, and
• at least one drill guide configured to guide a drill bit and positioned so as to guide the drill bit to form a second bore in the shoulder at a location spaced apart from the first bore,
• wherein the reaming section and the boring section are positioned with respect to each other such that when the combination device is positioned against the glenoid and the rotational force is applied to the drive section, the boring section rotationally forms the first bore in the glenoid and the reaming section simultaneously rotationally reams a portion of the glenoid adjacent to the first bore.
