腰椎骨盆固定在骶骨肿瘤切除重建中的应用

Application of lumbar-pelvic fixation in lumbosacral reconstruction after resection of sacral tumors

目的探讨腰椎骨盆内固定术重建骶骨肿瘤切除术后稳定性的可行性及近期临床疗效。方法 15例骶骨肿瘤患者行后路或前、后路联合切口肿瘤切除,分别采用TSRH-3D、CDH-M8或ISOLA行腰椎骨盆内固定,根据术后X线片观察稳定性,评价该手术方法的可行性及临床疗效。结果所有患者术后恢复良好,术后X线片显示内固定稳定、可靠,临床疗效满意。结论腰椎骨盆内固定术是骶骨肿瘤切除术后重建腰骶稳定性的一种固定牢固、可靠的手术方法。

Objective To evaluate the short-term clinical results of a new approach of lumbar-pelvic fixation for lumbosacral reconstruction after resection of sacral tumors. Methods Fifteen patients with sacral tumors underwent lumbar-pelvic fixation using TSRH-3D, CDH-M8 or ISOLA with iliac screws. The lumbosacral stability was evaluated according to the X-ray result to assess the feasibility and therapeutic effect of this approach. Results X-ray showed that high lumbosacral stability was achieved in all the 15 cases after the operation, and satisfactory therapeutic effect was obtained. Conclusion Lumbar-pelvic fixation with iliac screw is feasible for lumbosacral reconstruction after resection of the sacral tumors, which provides strong internal fixation and produce good clinical outcomes.
