Structural and functional reconstruction after resection of aneurysmal bone cyst of the fifth metatarsal: a case study.
We report a case of a primary benign bone tumor (aneurysmal bone cyst [ABC]) involving the distal portion of the fifth metatarsal, identified in an adolescent. The tumor, histologically identified as an ABC with reparative giant cell reaction, became symptomatic. Treatment included resection, followed by reconstruction of the fifth metatarsal using grafts of autologous bone with preservation of function in the metatarsophalangeal joint. The basis for selecting this form of treatment is discussed, as well as the natural history of ABC and giant cell reparative granuloma. Restoration of form and function is illustrated by this case study with a 23-month follow-up.
