To investigate the effects of surgical treatment and prognosis of aneurysmal bone cyst (ABC) in mobile spine.
A total of 12 patients with ABC were operated on from 1996 to 2006, and the clinical data were retrospectively reviewed. The patients included 7 male and 5 female, aged from 16 to 52 years (mean, 29 years). Surgical interventions were selected according to WBB criteria. Seven patients underwent total spondylectomy, four underwent resection of posterior arch, one patient received sagittal resection only. Anti-poster or post-lateral approach reconstruction with bone-graft or bone cement and transpedicular screws fixation were performed in the cases. Eight cases received radiotherapy after the operation.
The mean operation blood lose was 3210 ml. The patients were followed-up for 10 to 116 months (mean, 41.8 months). Seven patients got complete recover of spinal cord function, 4 patients experienced local recurrence in 1-2 years post operation. One patient died of multiple metastasis of chondrosarcoma after radiotherapy.
ABC in spine is an aggressive disease with high local recurrence rate. Enbloc if possible provides the best result, with excellent prognosis. Radiotherapy should be selected carefully.
探讨活动脊柱动脉瘤样骨囊肿（ABC）的手术治疗效果及预后。
回顾性分析1996年至2006年期间接受手术治疗的12例ABC患者的临床资料。患者包括7例男性和5例女性，年龄16至52岁（平均29岁）。根据WBB标准选择手术干预方式。7例行全脊椎切除术，4例行后弓切除术，1例仅行矢状位切除术。术中采用植骨或骨水泥及椎弓根螺钉固定进行后外侧入路重建。8例术后接受放疗。
平均手术出血量为3210毫升。患者随访10至116个月（平均41.8个月）。7例患者脊髓功能完全恢复，4例术后1至2年局部复发。1例患者放疗后死于软骨肉瘤多发转移。
脊柱ABC是一种侵袭性疾病，局部复发率高。尽可能整块切除可获得最佳效果及良好预后。放疗应谨慎选择。
