SNAPPING SCAPULA SYNDROME DUE TO SOLITARY OSTEOCHONDROMAOF THE SCAPULA – CASE REPORT
Osteochondroma or exostosis is a benign bone tumor, located mainly in the metaphysis of the long bones and involving the scapula in only 3-4.6% of all cases. Due to mass effect, it may produce various manifestations when it is located on the anterior surface of the scapula. The snapping scapula syndrome is a rare condition caused by the disruption of the gliding between the posterior chest wall and the scapula's anterior surface. Authors report a rare presentation of osteochondroma on the antero-medial side of the scapula in an 11-year-old boy, who had abnormal range of motion, associated with pain and a grating sensation being present when the arm was actively and passively abducted and/or elevated. The patient’s history, clinical examination and imagistic were relevant for osteochondroma of the scapula. The case was successfully managed by an open excision. The histological examination confirmed the clinical diagnosis of osteochondroma. The symptoms resolved immediately after surgery. Osteochondroma should be taken into account as a differential diagnosis in any adolescent presenting with snapping scapula syndrome.
