Early clinical and radiological evaluation of unilateral biportal endoscopic unilateral laminotomy bilateral decompression in degenerative lumbar spinal stenosis: A retrospective study – Lumbar Spinal Stenosis

The article evaluates the effectiveness of unilateral biportal endoscopic unilateral laminotomy bilateral decompression (UBE ULBD) for treating central lumbar spinal stenosis. The study included 41 patients who underwent the procedure, and their clinical outcomes and radiological parameters were assessed preoperatively, postoperatively, and at the last follow-up. Results showed significant improvements in visual analog scale (VAS) back and leg pain, Oswestry Disability Index (ODI) score, and various radiological parameters such as the cross-sectional area of the spinal canal, anteroposterior diameter, and lateral recess height. The study concludes that UBE ULBD surgery is a safe and effective treatment for central lumbar spinal stenosis, but further research with larger samples and longer follow-up periods is needed

ABSTRACT

PURPOSE: To evaluate changes in radiological parameters and clinical outcomes following unilateral biportal endoscopic unilateral laminotomy bilateral decompression for treatment of central lumbar spinal stenosis.

METHODS: Forty-one central lumbar spinal stenosis patients who underwent unilateral biportal endoscopic unilateral laminotomy bilateral decompression (UBE ULBD) were enrolled from April 2021 to February 2023. Visual analog scale (VAS) back pain, VAS leg pain, Oswestry Disability Index (ODI) score and the modified MacNab criteria were assessed preoperatively, postoperatively. The preoperative and postoperative cross-sectional area of the spinal canal (CSAC), anteroposterior diameter, horizontal width, ipsilateral and contralateral lateral recess height were calculated from axial computed tomography (CT) scans. Percentage of facet joint preservation measured on axial CT scans obtained pre-operation and post-operation.

RESULTS: The VAS back and leg pain improved from 7.24±0.80, 7.59±0.59 preoperatively to 2.41±0.55, 2.37±0.62 (P<0.05) postoperatively and 1.37±0.54, 1.51±0.55 at the last follow-up (P<0.05). For ODI, improvement from 60.37±4.44 preoperatively to 18.90±4.66 (P<0.05) at the last follow-up was observed. CT scans demonstrated that the postoperative CSAC increased significantly from 287.84±87.81 to 232.97±88.42 mm (P<0.05). Mean postoperative anteroposterior diameter and horizontal width increased significantly from 18.01±3.13, 19.57±3.80 mm to 22.19±4.56, 21.04±3.72 mm (P<0.05). The ipsilateral lateral recess height and contralateral lateral recess height was 3.39±1.12, 3.20±1.14mm preoperatively, and 4.03±1.37, 3.83±1.32 mm (P<0.05) postoperatively, with significant differences. The ipsilateral and contralateral facet joint preservation were 88.17% and 93.18%, respectively.

CONCLUSION: The UBE ULBD surgery is a safe and effective treatment for central lumbar spinal stenosis, associated with significant improvement in clinical outcomes and radiologic parameters. Studies with larger samples and longer follow-up periods are needed for further research.
