脊柱骨巨细胞瘤及其外科治疗

目的：研究脊柱骨巨细胞瘤的影像学特点，探讨手术方式及其预后的影响。方法：５６例均行手术治疗，早期实施单纯肿瘤病灶切除术，后期施行肿瘤整块切除术和病椎次全切除术，同时给予坚强的内固定。结果：术后所有患者局部疼痛均有不同程度的缓解，７７．３％的患者神经体征得到改善。随访４２例（平均随访５年４个月）中预后良好无复发者２５例（５９．５％），局部仍有瘤灶存在但病变不超过术前者１１例（２６．２％），病变扩大，

Giant cell tumor of the spine and its surgical treatment

Objective: To study the radiographic manifestation on the giant cell tumor on the spine and to discuss the relationship between operation and prognosis. Methods: Operation were performed on 56 cases. Some were simple curettage of tumor lesion in the early stage, some were total resections of tumor or semi spondylectomy accompanied by strong inter fixation. Results: Pain were relieved in all cases postoperatively and the neurological defects were improved in 77.3% of all cases. Forty two cases were followed up and 25 cases (59.5%) had excellent healing with no recurrence. The tumor lesion still existed in 11 cases (26.2%, which did not exceed the lesion field before operation), 6 cases (14.3% ) worsened. Conclusion: The giant cell tumor of spine has its own specific radiographic feature. There is some recurrence in simple curettage of tumor lesion. The thoroughly en bloc resection of tumor or spondylectomy, bone fusion and strong inter fixation are the key points for successful surgical treatment, the clinic behavior of bone giant cell tumor is somewhat unpredictable.
