侧前方减压、植骨、内固定治疗胸腰椎爆裂骨折

Anterior decompression and grafting and internal fixation for thoraco-lumbar burst fractures

目的 探讨侧前方减压、植骨、内固定在治疗胸腰椎爆裂骨折中的作用 ,并比较国产改良金田钉棒 (Kaneda)装置、胸腰椎前路“Z”形钢板内固定系统 (ZplateTmanteriorthoraco lambarfixationsystem ,ZplateTMATL)及AO钉棒固定系统 (VentroFix) 3种技术的特点。方法 总结 1997年 3月～ 2 0 0 0年 3月应用胸腰椎前路内固定技术 ,治疗胸腰椎爆裂骨折 4 1例 (包括Kaneda 2 4例、Zplate 12例及VentroFix 5例 )。结果 随访 1.5年～ 4年 ,疗效满意 ,内固定可靠 ,植骨愈合 ,无断钉、断棒等并发症。结论 胸腰椎前路固定系统可早期重建脊柱的稳定性 ,在治疗胸腰椎爆裂骨折中具有重要的临床价值。比较结果显示 ,Zplate和VentroFix具有操作简便、安全、合并症少、固定材料生物相容性好、无磁性干扰。

Objective To discuss the efficacy of lateral anterior decompression and grafting and internal fixation for thoraco lumbar burst fractures and comparison of Kaneda divice, Zplate Tm anterior thoracolumbar fixation system and AO VentroFix.?Methods From March 1997 to March 2000,41 cases of thoraco lumbar burst fractures were treated by anterior fixation techniques(including 24 cases of Kaneda device,12 cases of Zplate Tm and 5 cases of VentroFix).?Results Forty one cases were followed up from 18 48 months and the results of treatment were clinically satisfactory. There was no complicaton related to the internal fixators,intrinsic stability was good, grafting healed.?Conclusion Anterior fixation techniques of thoraco lumbar spine could supply intrinsic stability in early stage by these fixation techniques.It provided important clinical value for treating thoraco lumbar burst fractures. The results have shown that Zplate TM and VentroFix has advantages of simple assembling, safety,less complications, good biocompatibity and devoid of ferromagnetic characters, less operation time and less blood lost.
