Painful Snapping and Pseudo-winging Scapula due to a large Scapular Osteochondroma.

Introduction: Osteochondromas are common benign bone tumours. They are usually seen in metaphyses of long bones and are seldom found in flat bones like scapula. When present in scapula, they may cause abnormal scapulothoracic movements leading to pain, snapping and winging of scapula.
