Epidural fibrosis is a common cause of pain after lumbar surgeries. There are no previous reports documenting profound limb weakness associated with epidural fibrosis. A 43-year-old woman uneventfully underwent microscopic discectomy. However, six additional surgeries were needed due to recurrent pain and weakness episodes, several days after the surgery. Operative findings were severe epidural fibrosis around the thecal sac and nerve roots. Epidural fibrosis excision did not prevent recurrent fibrosis; therefore, we performed a lordotic fusion with posterior column shortening to reduce neural tension and nerve-root stretching. Eventually, she became free from recurrent episodes of deteriorations and repetitive surgeries.
硬膜外纤维化是腰椎手术后疼痛的常见原因。之前没有文献报道过与硬膜外纤维化相关的严重肢体无力。一位 43 岁女性行显微镜下椎间盘切除术，手术顺利。然而，术后数天，因反复疼痛和无力发作，又进行了 6 次额外手术。手术发现硬脊膜囊和神经根周围有严重的硬膜外纤维化。硬膜外纤维化切除并不能防止复发纤维化；因此，我们进行了脊柱前凸融合及后柱缩短术，以减轻神经张力和神经根拉伸。最终，她不再反复发作，也无需再进行重复手术。
