Osteochondromas, the most common tumor of the scapula, are one type of bone abnormality that may cause symptomatic scapula pseudowinging. This type of scapula winging is structural and maybe associated with significant scapula crepitus. We describe a case of a scapular solitary osteochondroma, arised from the ventral surface of the scapula in a 15-year-old boy, produced pseudowinging and scapula crepitus. The winging and scapula crepitus are alleviated with resection of the bony abnormality.
