Lumbosacral fracture-dislocation is a rare occurrence. There are more than 73 cases reported in the English literature. We report on the imaging findings and surgical treatment in a patient suffered of unilateral traumatic L5-S1 dislocation associated with severe disruption of the posterior ligamentous complex. The patient underwent open reduction and stabilization of L4-S1 vertebrae with posterior instrumentation system. Open reduction and internal fixation was mandatory as post-traumatic ligamentous insufficiency would lead to abnormal motion. Operative treatment managed to produce a solid arthrodesis and restore stability of the lumbosacral junction. Follow-up revealed excellent results. This study reports a rare injury of the lumbosacral junction, and the literature concerning this unusual condition is extensively reviewed.
腰骶部骨折脱位较为罕见。英文文献中报道的病例超过73例。我们报告了1例单侧创伤性L5 - S1脱位伴后韧带复合体严重损伤患者的影像学表现及手术治疗情况。该患者接受了L4 - S1椎体后路切开复位及内固定术。由于创伤后韧带功能不全可导致异常活动，因此切开复位内固定是必要的。手术治疗成功实现了牢固的关节融合并恢复了腰骶关节的稳定性。随访结果良好。本研究报告了一种罕见的腰骶关节损伤，并对有关这种罕见情况的文献进行了广泛综述。
