A Study of The relationship between Level of Forth and Fifth Lumbar spines and Deformity and Instability in Lumbar spondylosis Patients

Abstract

          Objective : The purpose of this research is to study relationship about level forth and fifthlumbar spines and clinical and deformity and instability of lumbar spines in lumbar spondylosis.
          Methodology : A retrospective study was performed in Nangrong Hospital from June 2007to March 2008. All of 200 patients were diagnosed lumbar spondylosis. This study had recordedclinical and deformity and instability from plain x-ray and level of fifth and forth lumbar spineswhich compare with posterosuperior iliac spines. The statistical tools used ANOVA, Multiplecomparisons, Linear regression, Correlation, Scheffe analysis. Program computer statistical analysisis used for data analysis at a statistical level of .05.
          Results : The research results indicate that the majority of patients are female with backpain dominant symptomatic , mean age 58.66 years. The level of forth and fifth lumbar spineswere related to instability angle L4L5,L5S1 and instability translation L5S1 .( P value .003, .007, .000)
          Conclusion : The research results represent the relationship between the level of the forthand fifth lumbar spines and instability angle L4L5, L5S1 and instability translation L5S1, especiallythe instability translation L5S1 is strongly relation with level of forth and fifth lumbar spines.
