全脊椎切除、内固定重建治疗胸椎肿瘤

Total spondylectomy and internal fixation to therapy thoracic vertebrae tumors

目的探讨全脊椎切除、内固定重建治疗胸椎肿瘤的手术指征及疗效。方法在WBB分区指导下对l2例胸椎肿瘤患者采取全脊椎切除、减压植骨及内固定重建。本组12例中,肿瘤病灶均同时累及WBB4-9区和10-3区。单纯后路内固定5例,前后联合入路7例。结果随访6个月～7年,1例神经症状无改善,其余疗效均较为满意。3例术后10～36个月肿瘤复发。结论对同时累及WBB4-9区和10-3区的胸椎肿瘤病人采取全脊椎切除、内固定重建,稳定性好,肿瘤切除彻底,是一种有效的手术方法。

【Objective】 To investigate the clinical inditions and effect of total spondylectomy and internal fixation to therapy thoracic vertebrae tumors.【Methods】 12 patients with thoracic vertebrae tumors were treated through total spondylectomy and internal fixation according to WBB.Tumors involved in W BB4-9 and 10-3 simultaneously.Posterior internal fixation were applied in 5 cases,anterior comined posterior total spondylectomy and internal fixation were performed in 7 cases.【Results】 The following-up period was from 6months to 7 years,years.The efficency was satisfactory except that 1 case has not im proved the neurological sym ptoms.3 cases tumor recurred in 10 to 36 months after operation.【Conclusion】 Total spondylectomy and internal fixation according to WBB are efficient for patients with thoracic spinal tumors involved in W BB4-9 and 10-3 simultaneously,can thoroughly clear tumor tissue and attain satisfactory stability.
