Surgical intervention is critical to reverse the stretching of the spinal cord. Here, we describe a technique for spinal cord untethering without dural opening in these patients. Methods: Three patients underwent spinal cord untethering without dural opening. The surgical technique involved reopening the previous incision and dissecting the scar tissue attached to the dura. A Spongostan sponge was inserted, and lateral sutures were placed between the dural sac and the adjacent muscles. Clinical outcomes, imaging findings, and urodynamic results were evaluated postoperatively. Results: The technique demonstrated positive outcomes in all three cases. Patients showed symptom improvement, better positioning of the spinal cord on imaging studies, and enhanced bladder function on urodynamic evaluations. Conclusion: Spinal cord re-untethering without dural opening may be a viable surgical option for selected patients with MMC, offering favorable outcomes with reduced risk.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/452e471d-9c7a-428b-8bdb-5d5fbab9e0c9/featured/hero-1781558944493.png","publishDate":"2025-01-10T00:00:00.000Z","doi":"10.25259/SNI_114_2024","categories":["Pediatric Neurosurgery","Technical Note"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2025/01/13327/SNI-16-7.pdf"}
