脊柱肿瘤的全脊椎切除术及脊柱稳定性重建

目的探讨对脊柱肿瘤行全脊椎切除术的可行性与临床价值,以及重建脊柱稳定性的可靠方法。方法对27例椎体和附件结构均遭破坏的脊柱肿瘤采用全脊椎切除及内固定重建技术进行治疗,其中包括上颈椎至下腰椎的良、恶性及转移性肿瘤,手术切除1～3节脊椎。结果23例获完整随访,随访时间7～96个月(平均25个月)。1例L5恶性神经纤维瘤及1例C6,7巨细胞瘤于术后10个月及12个月复发,患者放弃治疗;1例C2～4脊索瘤术后1年复发,再次手术效果良好;其余20例未见复发。25例术前伴神经功能损害者,术后有23例获显著改善。结论全脊椎切除术为治疗全脊椎受累脊柱肿瘤的有效方法;切除1～3节脊椎的脊柱可由相应内固定系统进行可靠的稳定性重建。

Spinal tumors treated with total spondylectomy and spinal stability reconstruction

Objective To evaluate the possibility and clinical value of total spondylectomy for the treatment of spinal tumors and to investigate a reliable method of spinal reconstruction after total spondylectomy. Methods Twenty seven cases of spinal tumors which eroded both vertebral body and its attachments were treated with total spondylectomy and internal fixation as reconstruction techniques. There were benign, malignant and metastatic tumors, which involved different levels from upper cervical to lower lumbar spines. One to 3 spinal vertebrae were removed. Results Twenty three cases were followed up for 7 to 96 months (with an average of 25 months). Among them, 1 case of L 5 malignant neurofibroma and 1 case of C6,7 giant cells tumor recurred in 10 and 12 months after operation, but the patients refused further treatment. One case of C2-4 chordoma recurred 1 year after operation, after second surgery, the result was satisfactory. No recurrent signs were found in the rest of 20 cases. Among 25 cases with neurological lesions, obvious improvement were obtained in 23 after operation. Conclusion For patients with involvement of spinal vertebra eroded by tumors, total spondylectomy is an effective procedure. After total spondylectomy, spinal stability can be reconstructed by stable internal fixation system.
