Minimally-invasive excision of a scapular osteochondroma on the ventral surface: A case report and literature review.

Key Clinical Message: Osteochondroma on the ventral scapula is clinically rare and can incur pseudo-winged scapula and snapping syndrome if not treated. In this regard, surgical excision is suggested, if possible, with a minimally invasive approach to accelerate physical recovery.

Abstract: Osteochondroma is a common benign bone tumor, characterized by a cartilage-capped osseous protuberance with cortical and medullary continuity with the underlying native bone. Osteochondroma is commonly found in the long bones, such as the proximal humerus, distal femur, and proximal tibia, but rarely seen in flat bones. We report a case of pedunculated osteochondroma on the ventral surface of left scapula in a young adult woman. She presented with a slight pseudo-winged scapula, occasional pain, and snapping sound with motion of the left shoulder. The tumor was surgically resected using a minimally invasive approach, and an excellent outcome was obtained.
