Review Question - QID 109684

A 17-year-old man presents to the emergency department after a motor vehicle accident. He was a front seat unrestrained passenger in a head on collision. The patient is currently stable and able to converse with the physician. His temperature is 99.5°F (37.5°C), blood pressure is 127/68 mmHg, pulse is 100/min, respirations are 17/min, and oxygen saturation is 98% on room air. A full trauma evaluation is only notable for a painful and angulated distal radius. The patient's radius is reduced and casted, and he is able to be discharged from the emergency department with follow up. The patient does not attend follow-up and attempts to reach the patient are not successful. Two months later, the patient presents to his primary care physician saying that he experienced severe pain while traveling abroad and had the cast removed at a local clinic. The finding seen in Figure A is observed. Which of the following is most commonly associated with this patient's presentation?
