腰椎棘突椎板截骨回植治疗腰椎管狭窄症的疗效观察及术后感染预防

Clinical Effect of Osteotomy and Regrafting in situ with Spinous Process and Vertebral Plate Complex for Canaloplasty in Lumbar Spinal Stenosis

目的观察腰椎棘突椎板截骨回植治疗腰椎管狭窄症的临床疗效,并探讨如何预防术后感染。方法采用棘突椎板等后柱结构完整截骨,椎管扩大,回植复合体,椎管重新成形。结果术后随访,椎管无明显狭窄,回植骨块位置良好,临床疗效较好;术后4～12周出现5例患者伤口局部脓疱、窦道形成。结论保留脊柱后方韧带复合体椎管成形术治疗腰椎管狭窄症取得较好临床疗效,但应注意术后切口感染的发生。

OBJECTIVE To explore the clinical effect of the application of osteotomy and regrafting in situ with spinous process and vertebral plate complex for canaloplasty in lumbar spinal stenosis.METHODS The whole spinous process and vertebral plate and regrafting in situ were taken out after the lesion in spinal canal cleared,so as to reform the canaloplasty.RESULTS By performing the postoperative follow-up,no significant spinal canal stenosis was found,back bone block position was good,and the clinical efficacy was also good.CONCLUSION Retention of the rear spine spinal ligament complex angioplasty is conducive to maintain the mechanical stability of the spine and can achieve good effect,but the preoperative incision infection should be noticed.
