Report of three cases.
To describe a rare location of intervertebral disc migration.
Migration of sequestered disc fragments to the posterior extradural space is rare, and posterior migration of the free fragments causing cauda equina syndrome is exceptionally rare.
Three patients with posteriorly migrated epidural disc fragments were evaluated with radiograph, computed tomography, and magnetic resonance imaging and underwent surgery.
All of the patients responded well to operative therapy with complete relief of symptoms.
Early surgery should be the first choice of therapy in patients with large posteriorly migrated sequestered disc fragments, to prevent severe neurologic deficits such as cauda equina and conus medullaris syndromes.
三例病例报告。
描述椎间盘移位的罕见部位。
游离椎间盘碎片向后硬膜外间隙移位罕见，游离碎片向后移位导致马尾综合征极为罕见。
对三例硬膜外椎间盘碎片向后移位的患者进行了X线、计算机断层扫描和磁共振成像评估，并接受了手术。
所有患者对手术治疗反应良好，症状完全缓解。
对于游离椎间盘碎片向后大量移位的患者，早期手术应作为首选治疗方法，以预防严重神经功能缺损，如马尾综合征和圆锥综合征。
