What’s causing this weightlifter’s “Popeye” arm? Let’s diagnose.

A 48-year-old man presented to the doctor with complaints of elbow pain that developed on his right arm after weightlifting earlier that day. He was performing a biceps-strengthening exercise with a weighted barbell when he felt and heard a popping sound and experienced pain around his right elbow.

On examination, diffuse ecchymoses at the medial arm and a reverse “Popeye” deformity of the arm were observed. X-ray examination ruled out fractures and avulsions. A positive hook test demonstrated a complete tear, and there was weakness with elbow flexion and supination. The patient denied anabolic steroid use. The patient was healthy and had no relevant medical history.
