This report concerns 35 adult patients with lumbar or sciatic pain and axial CT findings reportedly associated with posterior apophyseal ring fractures. Review of the CT images suggested two pathophysiologic categories. (1) Posterior Schmorl--A posterior intravertebral disc herniation with posterior displacement of a fractured or remodelled vertebral margin. (2) Calcified subligamentous--Reactive annular and or posterior longitudinal ligament calcification at the periphery of a herniated disc with or without remodelling and anterior displacement of the posterior vertebral margin.
本报告涉及35例患有腰部或坐骨神经痛的成年患者，其轴向CT表现据报道与后缘骨骺环骨折相关。对CT图像的回顾提示了两种病理生理类型。（1）后Schmorl型——后位椎间盘突出伴骨折或重塑的椎体边缘向后移位。（2）钙化韧带下型——椎间盘突出周围反应性环状和/或后纵韧带钙化，伴或不伴后椎体边缘重塑和向前移位。
