Spinal Pelvic Parameters Evaluation Of Spondylolysis Lumbar Olisthe Preoperative Assessment And Postoperative Results

Objective Analysis of normal adults with lumbar olisthe before and after surgery in patients with pelvic sagittal position parameters of the imaging characteristics and the parameters in the differences between the preoperative and postoperative normal adults,analysis of various parameters affecting the efficacy of surgery,postoperative clinical surgical treatment for lumbar spondylolysis sex slippage to provide certain reference.Methods Collected in September 2014-September 2014,zhengzhou university Yi Fu Yuan 58 patients with surgical treatment of lumbar olisthe,preoperative spinal pelvic parameters were measured and recorded,as lumbar olisthe preoperative group;Measuring spinal pelvic parameters and record after the surgery,as lumbar olisthe postoperative group,at the same time outpatient lumbar spinal curve pelvis collected 60 cases of normal people as normal control group.Surveys the Oswestry scores of preoperative and postoperative group,and measured the preoperative group of postoperative spinal pelvic parameters of group and the control group.Including the following data: PI,pelvic incidence Angle,PT,pelvis,sacral slope Angle,slope Angle,SS LL-lumbar lordosis Angle,TK-after thoracic convex Angle,SVA,sagittal balance,LSJA-lumbar di ministry joint Angle.According to the survey of the Oswestry scores after surgery patients divided into two groups: low period group(period is less than 50%)and high period(period is more than 50%);.Preoperative group,the group of patients with spinal postoperative pelvic comparative analysis between parameters and the control group by t test;Preoperative and postoperative group compared with paired t test;Using Pearson correlation coefficient to evaluate the correlation of the parameters;Low period and high period group compared with t test between;Period and the analysis of the relationship between the parameters using linear regression analysis;P < 0.05 was considered difference was statistically significant.Results 1.PT lumbar olisthe postoperative group,SS,LL,TK,SVA,LSJA and preoperative group had obvious difference(P < 0.01),postoperative PT,TK is higher than preoperative group,LL,SS,LSJA,SVA group is lower than the preoperative;Have obvious difference between preoperative group and normal control group(P < 0.01),preoperative group,PT,SVA,PI,LL,SS LSJA were higher than in normal control group,and TK is lower than the normal control group(table 2,3).2.The preoperative group compared with normal control group,the value of PI have obvious difference,and preoperative group of PI value is higher than the control group,the PI value of preoperative and postoperative group,no difference(table 2,3).3.The preoperative and postoperative group and normal control group pelvic parameter correlation analysis:(1)the normal control group each parameter correlation analysis: PI with SS,PT,LL,LSJA correlation;SS with LL,PT,SVA,and correlated with LSJA(table 4).(2)the preoperative set each parameter correlation analysis: PI and PT,SS,LL,and correlated with LSJA with SS,LL and LSJA significantly related;LSJA related to SS,PT and LL,SVA and PT,LL,and TK related(table 4).(3)set the parameter correlation analysis: the PI related to SS,PT and LL,SS associated with LSJA,PT and LL,SVA associated with TK and LSJA.The SS have significant correlation with LSJA(table 4).4.High SS,LL,LSJA period group,SVA is lower than the low period group(P < 0.05),and PT,TK is higher than low period group(P < 0.05)(table 5).Oswestry scores period and each parameter correlation analysis: SS,LL,LSJA has significant correlation with Oswestry grading period,the most significant correlation of LSJA(table 6).Conclusion 1.A whole spinal sagittal pelvic multiple parameters abnormal joint action,affects the spondylolysis of lumbar olisthe occurrence and progress.2.The high value of PI may be an important cause of spondylolysis lumbar olisthe and progress.3.The operation can improve the patients with spinal balance,PT,LL,were significantly correlated with LSJA and Oswestry grading period prompt attention to this a few parameters in operation adjustment,and that several parameters to improve the situation can forecast the healing of patients.
