Aneurysmal bone cyst. Long-term results and functional evaluation.
A study was performed on 13 patients with 16 primary aneurysmal bone cysts (ABC) to assess long-term results and functional outcome. The average age at diagnosis was 19.8 years. The anatomical sites were femur (4), tibia (5), humerus (2), fibula (2) and other (3). Four ABC's required no treatment. One patient underwent radiotherapy for an ABC of the spine. Eleven ABC's were treated surgically, mostly by intracapsular resection and bone grafting. Three patients had a total of 6 recurrences, which needed further treatment. At the time of follow-up (average period: 102 months), the average functional evaluation rate of 13 patients was 96%. These functional results were graded as excellent in 9 patients and good in 4.
