AI Article Synopsis
- Unilateral laminotomy for bilateral decompression (ULBD) is a minimally invasive surgery that effectively relieves symptoms of lumbar spinal stenosis while minimizing risks like blood loss, muscle damage, and pain compared to traditional methods.
- The study highlights a technique called slalom unilateral laminotomy for bilateral decompression with navigation, detailing ten steps to perform the surgery and reporting on a case series of seven patients who underwent the procedure.
- Results showed significant pain reduction post-surgery, with average pain scores dropping from 4.71 to 1.50 for back pain and 4.33 to 1.21 for leg pain, indicating it is a safe and efficient option for treating multi-segmental lumbar spinal stenosis.
Article Abstract
Background: Unilateral laminotomy for bilateral decompression (ULBD) is a MIS surgical technique that offers safe and effective decompression of lumbar spinal stenosis (LSS) with a long-term resolution of symptoms. Advantages over conventional open laminectomy include reduced expected blood loss, muscle damage, mechanical instability, and less postoperative pain. The slalom technique combined with navigation is used in multi-segmental LSS to improve the workflow and effectiveness of the procedure.
Methods: We outline ten technical steps to achieve a slalom unilateral laminotomy for bilateral decompression (sULBD) with navigation. In a retrospective case series, we included patients with multi-segmental LSS operated in our institution using the sULBD between 2020 and 2022. The primary outcome was a reduction in pain measured by Visual Analogue Scale (VAS) for back pain and leg pain and Oswestry Disability Index (ODI).
Results: In our case series (N = 7), all patients reported resolution of initial symptoms on an average follow-up of 20.71 ± 9 months. The average operative time and length of hospital stay were 196.14 min and 1.67 days, respectively. On average, VAS (back pain) was 4.71 pre-operatively and 1.50 on long-term follow-up of an average of 19.05 months. VAS (leg pain) decreased from 4.33 to 1.21. ODI was reported as 33% pre-operatively and 12% on long-term follow-up.
Conclusion: The sULBD with navigation is a safe and effective MIS surgical procedure and achieves the resolution of symptoms in patients presenting with multi-segmental LSS. Herein, we demonstrate the ten key steps required to perform the sULBD technique. Compared to the standard sULBD technique, the incorporation of navigation provides anatomic localization without exposure to radiation to staff for a higher safety profile along with a fast and efficient workflow.

Background: Cervical hyperextension injuries (CHI), commonly resulting in central cord syndrome and spinal instability, often affect the elderly with preexisting degenerative spinal changes, leading to a need for surgical interventions that address both the compression and stability of the cervical spine. This study compares the clinical outcomes of two posterior decompression and fixation procedures for treating cervical hyperextension injury in patients with preexisting multilevel spinal canal stenosis.
Methods: Patients suffering from cervical hyperextension injury combined with multilevel spinal stenosis were divided into two groups.

Objectives: Lumbar spinal stenosis (LSS) refers to a narrowing of the space within the spinal canal, which can occur at any level but is most common in the lumbar spine. Open laminectomy and minimally invasive laminectomy (MIL) procedures are the most common surgical gold standard techniques for treating LSS. This study aims to review clinical and biomechanical literature to draw comparisons between open laminectomy and various MIL techniques.

Introduction: With increasing life expectancy, degenerative lumbar spinal stenosis (LSS) has become a common problem in the geriatric population. LSS reduces the quality of life, limits daily activities, and requires therapeutic aids. We share our experiences of treating octogenarian patients with LSS with key lesion percutaneous single portal endoscopic unilateral laminotomy and bilateral decompression (sEndo-ULBD).
