The treatment of aneurysmal bone cyst.

The treatment of aneurysmal bone cyst. Forty-four patients with aneurysmal bone cysts were treated with curettage with or without bone grafting, and in 26 (59%) recurrence developed. Of 11 patients treated with radiation, in only 1 (9%) the disease was not controlled. In 1 patient, radiation-induced sarcoma developed. Since the introduction of cryosurgery 27 years ago, 51 patients have been treated with cryosurgery. The patients had an average age of 13 years (range, 2-32 years). Thirty-four primary aneurysmal bone cysts and 17 secondary aneurysmal bone cysts occurred in association with 7 giant-cell tumors, 5 chondroblastomas, 2 fibromyxomas, 2 nonossifying fibromas, and 1 unicameral bone cyst. The tumors were classified as inactive in 9 patients, active in 31, and aggressive in 11. Treatment consisted of local intralesional excision followed by application of liquid nitrogen. The defect was either allowed to heal spontaneously (n = 26) or was reconstructed using an intramedullary rod (n = 2), bone grafts (n = 5), fibular strut grafts (n = 14), or polymethylmethacrylate with Steinmann pins (n = 4). At median followup of 85 months (range, 24-311 months), the overall cure rate was 82%. This was increased to 96% after a second, or repeat, cryosurgery. The disease in all patients eventually was controlled by cryosurgery. The mean functional rating was 90% (range, 63%-100%). Intralesional excision with adjunctive cryosurgery is an effective method for the treatment of aneurysmal bone cyst. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Clinical orthopaedics and related research Pubmed

Since the introduction of cryosurgery 27 years ago, 51 patients have been treated with cryosurgery. The patients had an average age of 13 years (range, 2-32 years). Thirty-four primary aneurysmal bone cysts and 17 secondary aneurysmal bone cysts occurred in association with 7 giant-cell tumors, 5 chondroblastomas, 2 fibromyxomas, 2 nonossifying fibromas, and 1 unicameral bone cyst.
