本研究的目的是确定是否黄韧带肥大椎间盘突出患者引起对侧疼痛症状。因此，我们测量了有同侧或对侧症状的椎间盘突出患者的韧带厚度。将200例有同侧症状的椎间盘突出患者作为I组与5例只有对侧症状的椎间盘突出患者作为II组进行比较。采用磁共振成像（MRI）显微卡尺测量两组患者的黄韧带厚度和椎管直径。两组均仅在椎间盘突出侧进行手术。Ⅱ组黄韧带总厚度较Ⅰ组厚。两组均无椎管狭窄，组间无显著差异。两组同侧和对侧黄韧带厚度均存在统计学显著差异。我们还比较了组I中每个椎间盘突出水平的黄韧带厚度;女性腰椎L3-L4和L4-L5水平的黄韧带肥大更常见。椎间盘突出患者对侧坐骨神经痛的病因可能与黄韧带肥大有关，尤其是在对侧。仅椎间盘突出侧的手术入路可能足以获得良好的结果。
The purpose of this study was to determine whether ligamentum flavum hypertrophy among disc herniated patients causes contralateral pain symptoms. For this reason we measured the thickness of the ligament in disc herniated patients with ipsilateral or contralateral symptoms. Two hundred disc herniated patients with ipsilateral symptoms as group I were compared with five disc herniated patients with only contralateral symptoms as group II. Ligamenta flava thicknesses and spinal canal diameters of both groups were measured on magnetic resonance imaging (MRI) with a micro-caliper. Both groups underwent surgery only on the disc herniated side. The total thicknesses of the ligamenta flava in group II was thicker than in group I. There was no spinal stenosis in either group and no significance difference between the groups. Statistically significant differences were found for both ipsilateral and contralateral thickness of the ligament flava in both groups. We also compared thickness of the ligamenta flava for each level of disc herniation in group I; ligamenta flava hypertrophy was more common at L3-L4 and L4-L5 levels of vertebrae in females. Aetiology of contralateral sciatica among disc herniated patients may be related to hypertrophy of the ligamenta flava, especially on the opposite side. Surgical approaches of the disc herniated side alone may be sufficient for a good outcome.
