Abstract:
Objective To explore the clinical efficacy in bilateral lumbar foraminal stenosis (LFS) after treatment with bilateral facetectomy combined with pedicle screw fixation and interbody fusion.Methods A total of 41 cases of patients with bilateral LFS underwent bilateral facetectomy combined with pedicle screw fixation and interbody fusion from February 2010 to August 2013 in Department of Spine Surgery,the People's Hospital of Tianjin City,were retrospectively analysed.The clinical efficacy was assessed by Oswestry disability index (ODD questionnaire and visual analogue scale (VAS) before and after operation,anterior and posterior disc height and L1-S1 angle were measured as well.Then the ODI and VAS scores,and changes in anterior and posterior disc height and L1-S1 angle were calculated at the time of the last patient follow-up visit.Results All 41 patients were followed up for 12 to 36 months,with an average of (26.2±2.4) months.Compared with preoperation,at the time of the last follow-up visit the back pain VAS score,leg pain VAS score and ODI were decreased,while the anterior and posterior disc height were increased,there were statistically significant differences (P＜0.05).No statistically significant difference was found in L1-S1 angle between preoperation and postoperation (P＞0.05).Conclusion The short-term clinical curative effect of posterior bilateral facetectomy combined with pedicle screw fixation and interbody fusion in the treatment of bilateral LFS is satisfactory.
