رجل عمره ٥٨ سنة عنده ألم في الكتف عند رفع الذراع جانباً بين ٦٠ و١٢٠ درجة منذ شهرين، خاصة عند النوم على الكتف. يعمل دهاناً. ما الأرجح؟

A 58-year-old painter has had shoulder pain on raising the arm sideways between 60 and 120 degrees for two months, especially when lying on it. What is most likely?

1. Clavicle fracture
2. Rotator cuff impingement
3. Recurrent shoulder dislocation
4. Angina

Answer: B) Rotator cuff impingement. Painful mid-arc abduction with overhead work suggests rotator cuff impingement, treated with rest, physiotherapy, analgesia and sometimes injection.
