椎弓根内固定联合椎间融合在腰椎管狭窄症减压手术中的应用

The application of trans-pedicle internal fixation and intervertebral fusion in the decompression of lumbar spinal cannal stenosis

目的探讨应用椎弓根内固定联合椎间融合治疗腰椎管狭窄症的手术效果。方法回顾性分析2013年1月-2014年12月在我科行手术治疗的腰椎管狭窄症患者25例，术前常规行临床神经功能检查，腰椎正侧位、前屈后伸动力位x线片及MRI检查，术前术后应用ODI评估疗效。结果25例术后随访1-2．5年，平均1．5年，ODI由术前（64．02±7．49）分，改善至（25．81±6．92）分，差异有统计学意义（P〈0．05）。结论应用受累节段广泛椎板减压、椎弓根钉系统内固定、椎间cage植入融合的手术方式可以获得良好的临床疗效。

Objective To explore the surgical treatment of trans-pedicle internal fixation spinal canal stenosis and inter- vertebral fusion in the decompression of lumbar spinal cannal stenosis.Methods From January 2013 to December 2014, retrospective review of 25 cases with lumbar canal stenosis were given surgical treatment.Preoperative they were given routine clinical neural function examination,cinical neural function,lumbar positive side top after flexor stretch power X-ray and MRI.The curative effect were assessed with oswestry disability index before and after operation.Results All 25 cases were followed for 1 to 2.5 years,averaged 1.5 years.ODI was improved from （64.02±7.49）scores to （25.81± 6.92）scores after operation （P〈0.05）.Conclusion The good clinical efficacy can be obtained by trans-pedicle internal fixation spinal canal stenosis and intervertebral fusion.
