Q. A 42-year-old male presents to your clinic with a complaint of right arm pain and weakness after a recent injury. The patient reports that he was lifting weights at the gym when he felt a sudden pop in his arm, followed by severe pain and difficulty moving his arm. The patient reports a history of anabolic steroid use for the past 2 years. He also describes daily protein and creatine supplementation. His past medical history is significant for hypertension. The patient works as a bouncer at a sports bar. He denies alcohol or tobacco use.
On physical examination, the patient has a visible deformity in the right bicep region (see image), with a noticeable gap in the muscle. There is also marked weakness in elbow flexion and supination of the forearm. Ultrasound confirms a complete rupture of the long head of the biceps brachii distal tendon. The patient is advised of the potential risks and benefits of surgical intervention, and opts for surgical repair. The patient undergoes a successful bicep tendon repair and is started on a course of physical therapy. At follow-up visits, the patient demonstrates improvement in strength and range of motion, but still experiences some residual weakness.
Based on the most likely underlying etiology of his injury, which of the following additional disorders is NOT at an increased risk of developing, in this patient?
