摘　　要：Background:Prospective study objectives.A sagittal balance is a good tool to improve the functional outcome of spine spondylolisthesis surgeries,primarily noted that it has a good impact in deformity surgery and then applied to every spine surgery and the aim of this study is to evaluate its functional outcome when considered in preoperative planning for non-dysplastic low-and mid-grade spondylolisthesis surgeries.Method:Forty patients diagnosed as low-or mid-grade non-dysplastic spondylolisthesis had undergone surgery at Cairo University after failed medical treatment had been evaluated preoperatively by measuring the sagittal balance parameters which include SVA,spinopelvic angles,lumbar lordosis,pelvic tilt,sacral slope,and pelvic incidence and then measure it along a follow-up period of 1 year postoperatively started from February 2018 and correlate it with functional outcome using Oswestry score(ODI)and VAS.Correction of parameters has been estimated preoperatively by manual estimation and Surgimap application then applied during the operation.Results:All patients were treated by surgical treatment through posterior transpedicular screw fixation with conventional or reduction screws and fusion±TLIF cages.The mean of lumbar lordosis and mean spinopelvic angles were increased in a statistically significant manner.Pelvis tilt was decreased in a statistically insignificant manner.The mean of pelvic incidence was not changed and statistically insignificant,and this is matching the fact that pelvic incidence is a constant parameter.The sacral slope was increased in a statistically insignificant manner.Final results showed that 37 had a statistically significant improvement in their ODI>20%at the last visit.Three patients had a poor clinical outcome with ODI scorFinal results showed that 37 had a statistically significant improvement in their ODI>20%at the last visit.Three patients had a poor clinical outcome with ODI score of>20%improvement,and we noticed that the level of pathology was at the level of L4L5,SVA w
