شاب عمره ١٩ سنة بعد سقوط على الكتف، الكتف مسطح من الجهة الخارجية، ويمسك ذراعه بعيداً قليلاً عن جسمه ولا يستطيع تحريكه. عنده خدر في جلد أعلى الذراع الخارجي. ما الأرجح وما العصب المهدد؟

A 19-year-old fell on his shoulder; the shoulder looks flattened laterally, he holds the arm slightly away from his body and cannot move it, with numbness over the upper outer arm. What is likely and which nerve is at risk?

1. Anterior dislocation; axillary nerve
2. Clavicle fracture; ulnar nerve
3. Muscle tear; median nerve
4. Simple sprain; radial nerve

Answer: A) Anterior dislocation; axillary nerve. Anterior dislocation flattens the shoulder and may injure the axillary nerve (numb regimental badge area); nerve function is checked before and after reduction.
