Abstract:
Objective:To evaluate the efficacy of uniaxial PLUS endoscopic unilateral laminotomy for bilateral decompression (ULBD) technique in the treatment of lumbar spinal stenosis with Ⅰ° spondylolisthesis without clinical instability.Methods:A retrospective case analysis method was used to analyze the clinical data of 21 patients with lumbar spinal stenosis with Ⅰ° spondylolisthesis without clinical instability treated by uniaxial PLUS endoscopy via posterior ULBD technique in Shanxi Provincial People′s Hospital from May 2019 to May 2022. There were 10 males and 11 females, aged from 65 to 81 years, the average age was (69.00±3.62) years. The visual analogue scale (VAS), Oswestry disability index (ODI) and limp distance were evaluated before operation and at 3, 6 and 12 months after operation. The overall clinical efficacy was evaluated by MacNab score at 12 months after operation. Lumbar dynamic radiography was used to evaluate the stability of the lumbar spine before operation and at 3 months after operation. Measurement data were expressed as mean±standard deviation ( ± s), t-test was used for comparison before and after operation, and one-way repeated measures analysis of variance was used for comparison at different time points. Results:According to MacNab score, the results were excellent in 12 cases (57.1%), good in 6 cases (28.6%), fair in 2 cases(9.5%)and poor in 1 case(4.8%), the overall excellent and good rate was 85.7% (18/21). The VAS, ODI and limp distance at 3, 6 and 12 months after operation were significantly improved compared with those before operation, the differences were statistically significant ( P<0.01). There was no significant change in the stability of the lumbar spine dynamic position before and after operation. Conclusion:Uniaxial PLUS endoscopic ULBD technique can significantly improve the clinical efficacy in the treatment of lumbar spinal stenosis with Ⅰ° spondylolisthesis without clinical instability, and there is no significant change in stability after operation, and good clinical results can be achieved.
