经伤椎GSS内固定结合植骨治疗胸腰椎骨折42例

摘要

[目的]经伤椎通用型脊柱内固定系统(general spine system,GSS)内固定结合植骨治疗胸腰椎骨折临床疗效分析.[方法]42例胸腰椎骨折患者采用经伤椎GSS内固定结合经伤椎椎体内及椎间植骨治疗.分析比较术前、术后的伤椎前后缘高度、后凸Cobb's角,脊髓神经功能Frankel分级.[结果]42例患者手术均获成功,术中C臂机透视骨折椎体均良好复位.术前的伤椎前后缘高度、后凸Cobb's角分别为(45.8±14.4)％、(83.5±8.2)％、(23.6±9.3)°,术后分别为(92.7±5.9)％、(97.5±2.6)％、、(4.6±2.4)°,脊髓神经功能Frankel分级明显改善,4～12月植骨均获骨性融合.术前、术后各指标数据差异均有统计学意义(P＜0.05).[结论]采用经伤椎GSS内固定结合经伤椎椎体内及椎间植骨治疗胸腰椎骨折有效恢复伤椎高度,重建脊柱稳定性,增加植骨融合有效率.%[Objective] Analyse the clinical effect of thoracolumbar fracture treated with injured-vertebra GSS system internal fixation combining bone-grafting. [Method] 42 such cases took GSS system internal fixation combining inter-vertebra bone-grafting.Then analyse the front and back edges height, back-protruding Cobb's angle and spinal nerve function Frankel level of the injured vertebra. [Result] All patients had successful operation, the vertebra got good reposition with C-arm X-medical equipment; before operation, the injured vertebra front and back edges and back-protruding Cobb's angle were respectively (45.8±14.4)%,(83.5±8.2)%,(23.6±9.3)°, and were (92.7±5.9)%,(97.5±2.6)%,(4.6±2.4)° after operation; the spinal nerve function Frankel level was improved markedly, the bone-grafting in 4~12m got synostosis. All indexes had difference of statistical meaning between before and after treatment. [Conclusion] The method above can effectively recover injured vertebra height, reestablish spinal stability and increase bone-grafting sacrah'zation effective rate.
