title: Aneurysmal bone cyst of the fifth metacarpal.
abstract: Aneurysmal bone cyst is a rare, rapidly growing, and destructive benign bone tumor that even more rarely involves the bones of the hand. Various treatment options for aneurysmal bone cyst have been reported in the literature, but controversy exists regarding optimal treatment. Due to its rarity in the hand, no evidence-based treatment regimen has been established. A 21-year-old man presented with a history of pain and local swelling over his fifth metacarpal of 5 months' duration. Physical and radiographic examination of the hand was consistent with aneurysmal bone cyst. After biopsy, pathologic examination confirmed the diagnosis of aneurysmal bone cyst. En-block resection of the tumor and autologous bicortical strut graft fixation with Kirschner wires was performed. The hand was immobilized in a short arm cast for 3 weeks after the patient received 3 weeks of physiotherapy. Kirschner wires were removed 6 weeks postoperatively. Excellent clinical and functional results were obtained with no recurrence after 3 years of follow-up with en-block resection and reconstruction with iliac crest graft. Radiographic examination demonstrated the osseous integration of the graft with no signs of recurrence. Although treatment should be planned individually according to lesion site and size and to patient age, we suggest en-block resection to prevent recurrence and secondary surgical interventions particularly in cases with no articular involvement.
