The radiographic findings in 4 patients with fractures of the lumbar vertebral ring apophysis are reported. All patients had a bony ridge or fragment projecting into the spinal canal, usually from the lower border of L4; a defect in the postero-inferior aspect of the vertebral body; and either an anterior extradural impression or complete blockage on the myelogram. Computed tomography was performed on one patient and appears to be helpful in demonstrating bone within the spinal canal. Preoperative diagnosis can facilitate selection of the appropriate surgical approach.
报告了4例腰椎环突骨折患者的影像学表现。所有患者均有骨嵴或骨块突入椎管，通常来自L4下缘；椎体后下方有缺损；脊髓造影显示硬膜外前方有压迹或完全阻塞。对1例患者进行了计算机断层扫描，其似乎有助于显示椎管内的骨质。术前诊断有助于选择合适的手术入路。
