摘要
作者报告８例由黄韧带骨化（ＯＬＦ）引起的胸椎脊髓病。ＣＴ显示，骨化块多位于椎管的后侧和后外侧，呈结节状或山丘状改变，病变平面椎管狭窄，形态不规则。本组病例均行改进的扩大椎板切除减压手术治疗。术后平均随访４６个月，８例中４例症状完全缓解，行走接近正常，恢复轻体力工作；３例症状明显缓解、可较长距离行走，但步态僵硬；１例术前截瘫，术后可扶拐行走，括约肌功能正常。作者认为ＣＴ或ＣＴＭ是诊断ＯＬＦ的最好方法，“揭盖式”椎板减压术是一种安全有效的手术。
The authors reported 8 cases of thoracic myelopathy caused by ossiffication of the ligamentum flavum(OLF).As noted on CT,OLF was situated posterolaterally and/or posteriorly to the spinal cord,showed nodular or hill shape,and the spinal canal of the involved level was narrowing and irregular.Improved and extended laminectomy was performed in all 8 cases.The average time of follow up were 46 months.The symptoms in 4 cases had completely disappeared and they recovered light work.3 cases showed improvement in the symptomes and were able to walk longer distance with gait stiffness.One case of paraplegia before operation was able to walk with crutches and recovered sphincter function.The authors believed CT and CT myelography were the best method of diagnosis and the laminectomy of “uncovering lid”were a safe and effective operation.
