摘　　要：目的 探讨术后原位复发性腰椎间盘突出症的发生机理、影像学特征和治疗方法。方法12例病人均行再次手术治疗,采用原切口显露椎板残端进入椎管并将神经根通道做适当扩大,摘除髓核并对狭窄的神经根管进行减压,没有切除瘢痕组织。结果 本组10例经平均4.6年随访,优6例,良2例,可2例,优良率为80％。结论 椎间盘术后原位复发的主要原因是髓核遗留过多,影像学检查上MRI较CT更能清晰显示髓核突出的范围及大小。原位切口显露法摘除髓核可有效地去除病因,损伤小疗效满意,并对脊柱稳定性有利。Objective To study the pathological charge and the clinical characteristics of image of recurrent lumbar disc hemiation Methods 12 cases of the recurrent lumbar disc herination were treated with surgery.
