Introduction: Aneurysmal bone cyst (ABC) is one of most therapeutic challenging lesions for orthopedic surgeons specially in large-sized lesions and lesions, which are very close to important neurovascular structures. In the present study, we express our experience in the treatment of aneurysmal bone cyst by radiofrequency thermal ablation (RFTA).
Methods: In the last two years, we have treated 20 cases (12 males & 8 females) presented with painful aneurysmal bone cysts in different anatomical locations, the age mean (±SD) is 18.95 ± 8.02 years and median is 17.5 years, the mean size of the lesions (±SD) is: 32.25 ± 7.15 mm & the median (range) is 33.5 mm (18.0-43.0) mm. The treatment was done by (RFTA) only in 11 cases and by (RFTA) with cementation in the other 9 cases, then the patients underwent close clinical follow-up for clinical symptoms by using visual analogue scale (VAS) pain score & radiological follow-up for one month, six months & one year after the procedure.
Results: Close follow-up for the patients proved that (RFTA) is a clinically successful &curative treatment as there was significant reduction in the mean (±SD) of the (VAS) pain score in all treated cases from 8.40 ± 1.23 before the intervention to 0.20 ± 0.41 at the end of follow-up period. No recorded post-procedural complications or recurrence during or at the end of the follow-up period.
