Abstract:Objective To compare the clinical outcomes of unilateral versus bilateral pedicle screw fixation with transforaminal lumbar interbody fusion in lumbar stenosis. Methods From February 2015 to February 2016, in Zhuhai Hospital of Guangdong Hospital of Triditional Chinese Medicine, 60 lumbar spinal stenosis patients were selected, according to random number table, they were divided into two groups, treatment group (30 cases) were given unilateral versus bilateral pedicle screw fixation, and control group (30 cases) were given transforaminal lumbar interbody fusion. Clinical outcomes after surgery were evaluate by JOA and VAS, meanwhile, the lumbar spine lordosis angle (LL) and the pelvic incidence Angle (PI) were measured before and after surgery. Results JOA and VAS of two groups at same time were compared, the differences were not statistically significant (P > 0.05); JOA and VAS of two groups before surgery were compared with those after surgery, after surgery 3, 6, 12 mooths, the differences were statistically significant (P < 0.05). PI, LL of two groups at same time were compared, the differences were not statistically significant (P > 0.05); PI, LL of two groups before surgery were compared with those after surgery, after surgery 3, 6, 12 mooths, the differences were not statistically significant (P > 0.05). Conclusion Compared with ransforaminal lumbar interbody fusion, unilateral pedicle screw fixation has the same safe and effective outcome.
