Upper Limb Sports Injuries
A 45-year-old man felt a sudden "pop" in his right elbow while lifting a heavy box at work. He presents with anterior elbow pain, swelling, and weakness of elbow flexion and forearm supination. Examination reveals ecchymosis over the antecubital fossa, a palpable defect in the biceps tendon, and positive "reverse Popeye" deformity with the muscle belly retracted proximally. Hook test is positive (unable to hook finger under intact tendon at antecubital fossa). MRI confirms complete distal biceps tendon avulsion from the radial tuberosity.
