颈椎后路单开门颈椎管扩大成形术治疗脊髓型颈椎病远期疗效观察(1)
【摘要】目的 观察单开门椎管扩大成形术治疗脊髓型颈椎病远期疗效。方法 对62例脊髓型颈椎病患者采用单开门椎管扩大成形术治疗，随访时间5年1个月至12年3个月，平均随访7.5年。结果 术前JOA评分9.3±0.4，术后JOA评分11.4±0.4，末次随访JOA评分14.3±0.5，神经功能改善率65.2%。术前病程<6月组术后改善率与其他三组相比，P<0.05，术前MRIT1、T2高信号和T2高信号组术后改善率与信号无改变组相比，P<0.05，术前病情分级轻度组术后改善率与中、重度组相比，P<0.05。结论 颈椎后路单开门对脊髓型颈椎病安全有效，发病早期(病程<6月)行椎管扩大减压术可明显提高手术远期疗效；术前神经功能损害严重、合并有脊髓MRI T2加权高信号常常提示预后不佳。【关键词】脊髓型颈椎病;单开门;远期疗效
