半椎板切除全椎管减压治疗退行性腰椎管狭窄症的效果观察

Semi-laminectomy Decompression for Retrogression Lumbar Spinal Stenosis

目的:探讨半椎板切除全椎管减压治疗退行性腰椎管狭窄症的手术效果。方法:2005年7月-2009年6月手术治疗退行性腰椎管狭窄症的患者162例,均行半椎板切除全椎管减压结合椎弓根内固定及后外侧植骨融合术。结果:随访6～24个月,平均10.5个月,术后JOA评分由术前的(15.26±5.26)分提高到术后的(21.38±5.16)分(配对t检验P<0.05)。结论:行半椎板切除全椎管减压结合椎弓根内固定及后外侧植骨融合手术治疗腰椎管狭窄症既可以起到椎管彻底减压的目的,又可以尽可能保留脊柱后柱结构的稳定性及完整性。

Objective： To explore semi-laminectomy decompression for retrogression lumbar spinal stenosis （RLSS）. Methods： During July 2005 to June 2009, 162 patients with RLSS were operated on for semi-laminectomy decompression with pedicle screw fixation and posterolateral bone graft. Results： The patients were followed up for 6 to 24 months （average 10.5 months）. The JOA scores ofpreoperation （15.26± 5.26） was increased to those ofpostoperation （21.38± 5.16）（P〈0.05）. Conclusion： This surgical approach not only allows complete decompression of the spinal canal ,but also keeps the stability and integrity of the spinal posterior column.
