[Treatment of aneurysmal bone cyst]

The authors present the results of surgical treatment of 16 cases of aneurysmal bone cyst between 1998 and 2000. Age of patients at the onset of symptoms ranged from 5 to 15 years (average 11.3 years). In 12 cases the cysts were aggressive, and in 5 cases they were active (according to the capanne classification). In 12 cases the characteristic lining of the cyst was removed, curettage was performed and bone grafts were inserted into the bone cavity. In 3 cases autografts were used, in 2 cases both allografts and autografts were used, and in 7 cases only allografts were applied. Two cysts of the fibula were removed en-bloc, a cyst located in the scapule was treated with radiotherapy. In 15 cases the cyst was successfully managed surgically. While in 1 case a revision procedure was performed.
