Data presented are mean±SD. No significant difference (P>0.05) existed between groups at any time, Significant difference (P<0.05) existed before and after operation for VAS, ODI, and JOA at each time point in these groups. BPS=Bilateral pedicle screw, UPSFS=UPS plus contralateral translaminar facet screw, UPS=Unilateral pedicle screw, VAS=Visual analog scores, SD=Standard deviation, ODI=Oswestry disability index, JOA=Japanese Orthopaedic Association Scores
