Review Question - QID 218211

A 45-year-old male presents to your office with a chief complaint of elbow pain and weakness. He states he was lifting weights when he felt a pop in his antecubital fossa. On examination, he has ecchymosis in this region with tenderness over the radial tuberosity and weakness with flexion and supination. You diagnose a distal biceps rupture and recommend repair using a suspensory button through a single-incision technique. You review the risks and rehabilitation process with the patient prior to surgery. When describing the most common complication, what are the associated physical examination findings?
