Ans. C. Deltoid contractureThe above history and examination suggest a diagnosis of deltoid contracture.* Deltoid contracture can be congenital or acquired. Anatomical aberrations, repeated intramuscular injections into the deltoid, chronic infection due to the injected drugs and pressure ischemia are all causes of acquired contracture.* A patient with a deltoid contracture presents with inability to keep his arm in contact with the chest in the anatomical plane of the scapula. When the arm is forcibly brought into contact with the chest there is winging of the scapula. On palpation, a thick intermediate fibrotic deltoid is felt.
