(SBQ06TR.4)
A 58-year-old right-hand-dominant computer programmer trips and falls onto his right arm. He reports right arm pain and that his elbow felt "sloppy". His initial lateral radiograph is shown in Figure A. The orthopedic junior resident counsels him that he will likely need a radial head arthroplasty, ligament repair, and possible fixation of the ulna. What factor would most significantly affect the decision to surgically address the ulna fracture?
