Evaluation of the recurrence rate of aneurysmal bone cyst after different surgical reconstructive options

ABSTRACT

A review of 20 patients with aneurysmal bone cyst involving different anatomic locations in the skeleton who were evaluated and staged according to Enneking et al., [1-5] system as 11 active benign lesions [55%] and 9 aggressive benign lesions [45%]. Meticulous curettage was achieved in 15 patients and autogenous bone grafting was applied in 11 patients, 3 of them paternal bone grafting was used and in 4 cases no grafts was applied. In 5 patients resection of the affected bony tubular segment was achieved without reconstruction in 4 of them and a fibular grafting done for the fifth. The mean age at surgery was 16 years old. Union was achieved in all the cases at an average of 9 months. As regard the complications that needs reoperations was in 4 cases of local recurrence and graft resorption necessitating re-grafting, 2 cases with nerve palsy spontaneously improved during the follow up and one case with residual coxa vara which corrected after cyst healing. The mean follow up period was 22.4 months. The functional results of the procedure were rated as excellent in 18 cases [90%], fair in one case [5%], poor in one case [5%]. The end results of the procedure are justifiable for tumor surgery provides cyst healing and ossification with sufficient biological strength and durability with a stable limb and excellent functional end result:
