Case Description: A 40-year-old female developed an acute cauda equina syndrome (CES) attributed to an acute lumbar disc herniation and to marked canal stenosis due to OYL. As the patient underwent a 9 h delayed removal of the ossified ligament and discectomy, she sustained only minimal recovery. Conclusion: Patients diagnosed with acute lumbar disc herniation and severe stenosis due to OYL who present with acute CES warrant emergent surgical decompression to avoid permanent postoperative neurological sequelae.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/8d6a867e-348a-411f-9c3e-eb335ddd784a/featured/hero-1781562473450.png","publishDate":"2021-05-03T00:00:00.000Z","doi":"10.25259/SNI_319_2021","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2021/05/10782/SNI-12-202.pdf"}
