经皮椎间孔内镜治疗TLIF术后相邻节段椎间盘突出的疗效分析

经椎间孔入路腰椎椎体间融合术(transforaminal lumbar interbody fusion,TLIF)术后邻近节段退变(adjacent segment degeneration,ASD)发生率为25%~40%[1-2]。ASD再手术治疗有一定难度,手术风险较高[3-4]。本研究探讨经皮椎间孔内镜下椎间盘切除术(percutaneous transforaminal endoscopic discectomy,PTED)治疗TLIF术后相邻节段腰椎间盘突出症(lumbar disc herniation,LDH)的临床疗效。
