Two cases of posterior lumbar vertebral rim fracture and associated disc protrusion in adolescents are presented. Disc compliance and developing vertebral structure were thought to be primarily responsible for this unusual injury. Occurring primarily in adolescent males, this entity most commonly affects the L-4 vertebra. One of the cases involved disc rupture at three levels. This injury is thought to be due in part to union of the anuli by the posterior longitudinal ligament, and in part to rim fracture and limited prolapse rather than frank single-level herniation in an adolescent. A review of the embryology, literature, and theoretical mechanism for occurrence at multiple levels is included.
本文报告了两例青少年腰椎椎体后缘骨折并伴有椎间盘突出的病例。椎间盘顺应性和发育中的椎体结构被认为是导致这种特殊损伤的主要原因。这种情况主要发生在青少年男性中，最常累及L-4椎体。其中一例涉及三个节段的椎间盘破裂。这种损伤被认为部分是由于后纵韧带使纤维环联合，部分是由于椎体后缘骨折和有限的脱垂，而非青少年典型的单一节段明显疝出。文中还包括了对胚胎学、文献以及多节段发病理论机制的综述。
