BACKGROUND: The acromion and neck of the scapula are essential components of shoulder function, but the body section is less critical. We treated aneurysmal bone cysts (ABCs) of the neck and acromion with extended curettage and ABCs of the body with en bloc resection. This article reports on local recurrence and the functional outcomes of this approach.
MATERIALS AND METHODS: Seventeen patients with primary ABCs of the scapula were included in this retrospective study. We treated 10 patients with extended curettage and bone grafting and 5 patients with en bloc resection. In 2 cases, both the body and neck were involved. We treated these patients with a combination of curettage and resection. We used the Musculoskeletal Tumor Society score for functional assessment of outcomes.
RESULTS: The mean age of the patients was 20.5 ± 7.4 years. One local recurrence occurred in patients who underwent extended curettage and bone grafting (1 of 12 cases, 8.3%). No recurrence was observed in patients who underwent en bloc resection alone. The mean Musculoskeletal Tumor Society score was 27.9 ± 1 in patients who underwent curettage alone and 24.86 ± 0.7 in patients who underwent en bloc resection alone or in combination with curettage (P < .001).
CONCLUSION: Despite the higher risk of local recurrence after curettage, this method can be selected for the treatment of ABCs of the acromion and neck of the scapula to minimize shoulder disability. For the body of the scapula, en bloc resection is a more reasonable treatment, despite a higher rate of functional impairment.
