骶骨肿瘤手术治疗及TSRH-3D脊柱内固定系统的应用价值

Evaluation of Reconstruction of TSRH-3D Spine Internal Fixation on Sacral Tumor's Resection

目的：探讨在骶骨肿瘤手术中TSRH-3D脊柱内固定系统对于腰椎-骨盆连续性重建中的应用价值。方法：选择青海省人民医院骨科2006年9月～2011年12月收治的45例腰骶段骨肿瘤患者进行回顾性研究，其中原发性肿瘤41例，转移癌4例，行肿瘤切除术后并予TSRH-3D行腰椎与骨盆内固定进行腰椎-骨盆连续性重建，术后结合病理结果给予相对应的放疗与化疗。结果：术后随访8～36个月，2例术后出现排尿困难，4例术后切口感染及延期愈合。术后患者腰骶部疼痛症状及下肢根性疼痛症状均有不同程度改善，恢复正常行走及负重。5例脊索瘤患者于术后10～21个月复发，4例转移癌患者分别于术后12个月、16个月、20个月、20个月死亡，所有患者均未发生断钉、断棒及螺钉松动症状出现。结论：TSRH-3D脊柱内固定系统在骶骨肿瘤切除与重建术治疗中能有效保持腰椎-骨盆的稳定性，可以有效地缓解腰骶部疼痛，维持患者的行走负重功能。

ToIn order to investigate the Evaluation of the TSRH-3D internal fixation.Methods：In resection of sacrum tumors ： chooce the petiont from the department of orthopedics in Qinghai People’s Hospital, From Sep. 2006 to Dec. 2007, 45 cases with sacral tumor were included in this study, including 41 cases with primary tumors and 5 with metastasis cancers. All cases’ Lumbosacral reconstruction were followed by TSRH-3D internal fixation and corresponding chemotherapy and radiotherapy.Results：In the follow-up period of 8~36months,the results of short-term were satisfactory with the lumb-sacral pain reduced and the neurological function improved in different degrees, other 2 cases experienced cerebrospinal fluid leakage and 4 case experienced perative infection and delayed healing.5case with chondrosarcoma recurred 21 months after operation and 4 cases with metastasis cancer died of exhaustion 12 and 20 months respectively. No fracture rod occurred.Conclusion：TSRH-3D as a effective ways of achieving stabilization by Lumbosacral tumor resection and reconstruction ,providing significant pain relief and preserving ambulatory capacity.
