腰椎间盘突出症中直腿抬高试验阴性表现的临床意义

Negative Sign of Straight-leg Raising Test in Lumbar Disc Herniation

目的探讨椎间盘突出症中直腿抬高试验阴性的临床意义。方法通过物理检验、影像学表现、手术所见对直腿抬高试验阴性的椎间盘突出症患者进行直观的分析。结果神经根变性、个体致痛性不敏感、突出物位置、病理环境下的神经根病态平衡、病变间隙的椎管容积大、腰背肌保护性脊柱固定、职业因素等是造成腰椎间盘突出症患者直腿抬高试验阴性的主要原因。结论仔细分析临床症状,客观地参照影像学检查结果而排除直腿抬高试验阴性的原因是避免腰椎间盘突出症漏诊的重要方法。
