Abstract
A bone resection guide, particularly for an ulna, utilizes anatomical reference points of the ulna to establish an optimal position for a prosthesis. The bone resection guide provides a guiding instrument that allows a surgeon to remove only bone that needs to be removed for precise placement of the end prosthesis. A method of resecting bone from the ulna in preparation of prosthetic implantation using the bone resection guide matches an elbow axis finder with a particular size of an ulna fossa of the patient. Once matched, a sized resection template, directly related to the shape of the prosthesis, is used as a resection guide. Incorporated into the bone resection guide are known anthropometric qualities when providing resection surfaces. This enhances the probable position of the implant.
