ABSTRACT
Objective:To evaluate the efficacy of unilateral biportal endoscopy (UBE) in the treatment of central lumbar spinal stenosis.Methods:The retrospective case-control study was conducted. 36 patients with central lumbar spinal stenosis were treated by unilateral dual channel spinal endoscopy who underwent Beijing Mentougou District Hospital from November 2019 to September 2021 were collected. There were 19 males and 17 females, including 11 cases of L 5-S 1, 19 cases of L 4-L 5 and 6 cases of L 3-L 4; The age was (70.0±3.9) years old, and ranged from 55 to 82 years old. The observation indicators: the changes of dural sac area in lumbar magnetic resonance cross-section before and after surgery, and the improvement of visual analogue of pain (VAS) score and Oswestry dysfunction index (ODI) before and after surgery in 1, 3, 6, and 12 months, as well as the occurrence of complications. Measurement data with normal distribution were represented as mean±standard deviation ( ± s), and comprison between groups was conducted using the t test; Comprison between groups of count data was conducted using the chi-square test or Fisher exact probability. Results:Postoperative MRI showed that the area of the transverse dural sac increased from (65.5±6.7) mm 2 before operation to (173.5±5.5) mm 2 after operation after the removal of the ligamentum flavum ( P<0.05). The follow-up of 36 patients for 12 months after operation showed that the VAS score decreased from (8.5±2.0) scores to (1.3±0.8) scores, and the ODI decreased from (59.3±12.3)% to (13.6±1.6)%( P<0.05). No complications such as nerve injury, cerebrospinal fluid leakage and infection related to operation occurred in 36 patients. Conclusions:Unilateral biportal endoscopy is one of the safe and effective treatment methods in the treatment of central lumbar spinal stenosis, with obvious improvement in symptoms, and the increase in the area of the spinal dural sac. It can obtain good early clinical effects.
