Transforaminal lumbar interbody fusion (TLIF) is an effective treatment for patients with degenerative spondylolisthesis and degenerative disc disease. Opposite side radiculopathy after the TLIF procedure has been recognized in this institution but has not been addressed in the literature. We present a case of opposite side radiculopathy after the TLIF procedure. We believe that this complication is related to asymptomatic stenosis on the contralateral side that is unmasked by the increased lordosis of the TLIF. The authors recommend increasing both disc height and foraminal height when choosing an interbody graft, and possibly decompressing the opposite foramen when preoperative MRI demonstrates foraminal stenosis.
经椎间孔腰椎椎体间融合术(TLIF)是治疗退行性腰椎滑脱症和退行性椎间盘疾病患者的有效方法。本院已认识到TLIF手术后出现对侧神经根病的情况,但文献中尚未涉及。我们报告一例TLIF手术后出现对侧神经根病的病例。我们认为这种并发症与对侧无症状狭窄有关,TLIF导致的前凸增加使这种狭窄显现出来。作者建议在选择椎间融合器时增加椎间盘高度和椎间孔高度,并且当术前磁共振成像显示椎间孔狭窄时,可能需要对侧椎间孔减压。
