Surgical results in patients with unicameral and aneurysmal bone cysts

ABSTRACT SURGICAL RESULTS IN PATIENTS WITH UNICAMERAL AND ANEURYSMAL BONE CYSTS Unicameral and aneurysmal bone cyts are benign tumours which most often located in bones of children and adolescents. These lesions have different treatment options with high recurrence rates. Unicameral and aneurysmal bone cysts have different options for surgical treatment include percutaneous aspiration with injection of corticosteroids or bone narrow, decompression, resection, curretage with or without bone grafting or combinations of these options. We performed a retrospectif analysis of 20 patients with unicaneral bone cysts and 20 patients with aneurysmal bone cysts. 11 of patients were male and 9 of them were female in unicameral bone cysts and 12 of patients were male and 8 of them were female in aneurysmal bone cysts. The mean age of unicameral bone cysts was 19, 80 years (4-50) and the mean age of aneurysmal bone cysts was 21, 76 yesrs (4-56). 17 of the patients with unicameral bone cysts were terated by curretage and grafting, 2 of the patients were terated by percutaneous aspiration with injection of corticosteroids, 1 of the patient was terated by curretage and cementation, 14 of the patients with aneurysmal bone cysts were terated by curretage and grafting, 1 of the patient was terated by curretage and cementation, 1 of the patient was terated by curretage and bone filling material, 1 of the patient was terated by percutaneous aspiration with injection of corticosteroids, 3 of the patient were terated by resection. The mean follow-up period was 36 months (6-60). Recurrence were seen in 10 patients and 5 of the patients were in unicameral and 5 of the patients were in aneurysmal bone cysts groups. 4 of the recurrence in unicameral bone cysts were treated by curretage and grafting and 1 of the patient was treated by percutaneous aspiration with injection of corticosteroids. 3 of the recurrence in aneurysmal bone cysts were treated by curretage and grafting, 1 of the patient was treated by percutaneous aspiration with injection of corticosteroids and 1 of the recurrence was treated by resection. Unicameral and aneurysmal bone cyts are benign lesions. Surgical treatments usually give us good results. But, these lesions have high recurrence rate. For that reason, these patients should be seen every 3 months for first postoperative year, every 6 months for second year and annually after the second year.
