胸椎黄韧带骨化性椎管狭窄的治疗

Treatment of thoracic spinal stenosis of OLF

目的探讨漂浮法经根黄通道后路椎板切除治疗胸椎黄韧带骨化性椎管狭窄的远期效果。方法对22例胸椎黄韧带骨化性椎管狭窄行漂浮法经根黄通道后路椎板切除减压术。结果22例随访6～75个月,平均36.2个月,参考Epstein等的评价标准,优良率81.8%。术中10例损伤硬膜者6例经缝合或修补愈合,4例术后脑脊液漏者经引流等保守治疗方法治愈。结论漂浮法经根黄通道后路椎板切除减压术治疗胸椎黄韧带骨化性椎管狭窄,减压安全、彻底,可获得良好的治疗效果。

Objective To evaluate the long-term outcome of the surgical treatment of lamina floating technique with a modified predicel-ossified ligament floating en bloc laminectomy for the thoracic spinal stenosis caused by the ossification of spine ligamentum flavum. Methods Twenty-two patients with the ossification of flaval ligament in thoracic spine underwent the surgery of lamina floating technique with a modified predicel-ossified ligament floating en bloc laminectomy. Results The clinical outcome was evaluated according to Epstein Score System. The excellent rate and good rate was 81.8% altogether. Conclusions The lamina floating technique with predicel-ossified ligament en bloc laminectomy is a safe and effective procedure for the thoracic spinal stenosis caused by the ossification of spine ligamentum flavum.
