Arthroscopic Excision of Scapular Exostoses: A Technical Note

Background: Cartilaginous exostoses of the scapula are rare and can cause symptoms such as pain and mechanical crepitus due to scapulothoracic bursitis. While open surgical resection remains the standard approach, it is associated with significant tissue disruption and longer rehabilitation. This technical note presents a minimally invasive arthroscopic technique for excising scapular exostoses. Methods: We report the case of a 22-year-old female patient with a symptomatic ventral scapular exostosis. After confirmation of a benign lesion, the exostosis was excised en bloc under continuous arthroscopic guidance. The surgical procedure, including patient positioning, portal placement, instrumentation, and specimen removal, is described in detail. Results: The lesion was successfully excised as a single piece for histopathological analysis. The patient experienced no intra- or postoperative complications. Postoperative rehabilitation included early passive motion, and full recovery was achieved within six weeks. At 24-month follow-up, the patient remained pain-free with complete restoration of shoulder function and no evidence of recurrence. Conclusions: Arthroscopic excision of scapular exostoses offers a viable alternative to open surgery. The technique minimizes soft tissue trauma, supports faster recovery, and may be safely performed in experienced hands with appropriate preoperative planning and imaging.
