The authors have controlled the treatment results of 35 patients (26 males and 9 females) operated on because of Aneurysmal Bone Cyst (ABC) in the II Department of Orthopaedics and Traumatology of the Istituto Giannina Gaslini in Genoa. The diagnosis of ABC was confirmed by histology. Age in admission ranged from 2.7 to 13.2 years. ABC was more frequently localized in the long bones (71%), followed by rachis (14%). The metaphisis was affected in 22 cases out of 25; these localizations are classified according to Capanna et al. Of the 5 rachidian localizations, 3 were in the posterior arch and 2 also in the vertebral body. Treatment included, when possible, 'curetage' and grafting with auto- and homoplastic bone or 'curetage' only (vertebral or pelvic localizations), or resection (peroneal or costal localizations). The incidence of recurrence in the long bones was 40% and was not related to patient's age, type of graft or ABC size. Capanna type II juxtaepiphyseal lesions were characterized by a higher incidence of recurrence. Vertebral localizations did never relapse. Treatment of long bone recurrence included: 'curetage' (4 cases), cortisone infiltrations (3 cases), roentgenotherapy followed by infiltrations (1 case), resection and positioning of external device (1 case). Treatment of recurrence was always succesfull. Long term outcome (follow-up from 2 to 25 years) included: 6 shortening major of 3 cm 1 ankle varus and 1 thoracic kyphosis.
