BACKGROUND
Here, we reviewed the clinical, radiological, and neurological sequelae and treatment when transforaminal lumbar interbody fusion (TLIF) cages migrate into the lumbar spinal canal.
CASE DESCRIPTION
A 46-year-old female underwent a TLIF L3-L4. Five months later, she presented with cauda symptoms/signs of dorsal cage migration that warranted surgical removal.
CONCLUSION
TLIF can be associated with delayed dorsal cage migration into the spinal canal. This adverse event should be clinically recognized, radiologically documented, and appropriately surgically treated to minimize short/long-term neurological sequelae.
背景
在此，我们回顾了经椎间孔腰椎椎间融合术（TLIF）椎间融合器移入腰椎管时的临床、放射学和神经学后遗症及治疗情况。
病例描述
一名46岁女性接受了L3-L4节段的TLIF手术。五个月后，她出现了融合器向后移位至椎管的马尾症状/体征，需要进行手术取出。
结论
TLIF可能与融合器延迟向后移位至椎管有关。这种不良事件应在临床上得到认识，通过放射学记录，并进行适当的手术治疗，以尽量减少短期/长期神经后遗症。
