2. 82 patients of were divided into L4,5 hernia group, L_5S_1 hernia group and L_5S_1bulge group.
3. 46 patients of LDH were randomly divided into exercising abdominal musclegroup and normal control group.
Statistical methods Compared with multitude means on LSD of One-wayANOVA, and Compared with two means on t test of independent sampler.Confidence interval was 95％, P＜0.05 had significant difference.
Results: 1. There was not significant difference in angle of tilted sacrum、lumbar vertebrae curvatur、angle of lumbar vertebrae curvature and height of L_5S_1's discusintervertebralis on each ages. There was significant difference in included angle ofjuncturae lumbosacralis between 51-60 age group and≤30 age group(P=0.029＜0.05).There was significant difference in each group except 41-50 age group on includedangle of juncturae lumbosacralis, 31-40 age group compares with≤30 age group:P=0.005＜0.01, 51-60 group compare with≤30 age group: P=0.039＜0.05,＞60 agegroup compares with≤30 age group: P=0.008＜0.01; There was significant differencein≤30 age group comparing with other groups except 51-60 age group on anteriorarch angle of juncturae lumbosacralis. (31-40 age group vs≤30 age group:P=0.036＜0.05; 41-50 age group vs≤30 age group: P=0.005＜0.01;＞60 age group vs30 age group: P=0.028＜0.05)There was significant difference in anterior arch angleof juncturae lumbosacralis between 51-60 age group and 41-50 age group(P=0.018＜0.05). In exponent of L5 vertebral body,＞60 age group vs≤30 agegroup:P=0.016＜0.05;＞60 age group vs 31-40 age group: P=0.021＜0.05;＞60 agegroup vs 51-60 age group: P=0.014＜0.05; There was significant difference in angle oflumbosacral disc between≤30 age group and 51-60 age group(P=0.029＜0.05). Thereonly was significant difference in included angle of juncturae lumbosacralis and angleof juncturae lumbosacralis between male group and female group(P=0.007＜0.01,P=0.004＜0.01). There was significant difference in angle of lumbosacral disc andheight of L_5S_1's discus intervertebralis between lumbar intervertebral disc herniationgroup and CLBP group.(P=0.049＜0.05, P=0.007＜0.01). In addition, the significantdifference in angle ofjuncturae lumbosacralis (P=0.000＜0.01)、anterior arch angleof juncturae lumbosacralis (P=0.022＜0.05)、angle of tilted sacrum (P=0.000＜0.01),lumbar vertebrae curvature (P=0.000＜0.01)、angle of lumbar vertebrae curvature(P=0.010＜0.05) and exponent of L5 vertebral body(P=0.000＜0.01)between CLBPgroup and non-CLBP group.
2. The texture parameters of LLDH indicates the significant difference in lumbosacralangle lumbar vertebrae curvature and height of L_5S_1 intervertebral disc comparingcontrol group with L_5S_1 intervertebral disc herniation group、L_5S_1 bulge group、 L_(4,5)intervertebral disc herniation group. The significant difference in height of L_5S_1intervertebral disc among L_5S_1 intervertebral disc herniation group、L_5S_1 bulgegroup、L_(4,5) intervertebral disc herniation group. There was significant in height of L_5vertebral body between L_5S_1 intervertebral disc herniation group and L_(4,5)intervertebral disc herniation group. There was significant difference in lumbarvertebrae curvature between L_5S_1 intervertebral disc herniation group and L_5S_1 bulgegroup. The same consequence in ratio of disc and vertebra among L_5S_1 intervertebraldisc herniation group、L_(4,5) intervertebral disc herniation group and control group.L_5S_1 bulge group compared with L_(4,5) intervertebral disc herniation group (P＜0.05).There was not significant difference in facet joint at L_5S_1 level among four groups
3. It also had significant difference in lumbar vertebrae Flexed function betweenabdominal muscle functional exercise grouop and common functional exercise group.
Conclusion: 1. Lumbosacral angle and anterior arch angle of lumbosacral differentages of CLBP patients had significant difference, compared with the normalgroup,except the lumbosacral angle, lumbosacral disc angle and height of L_5S_1 disc,the others were significant differences.
2. In different sex lumbar vertebra bone structure datas of CLBP patients, lumbosacralarticulation and lumbosacral angle were significant differences.
3. Low lumbar intervertebral disk hernia had significant changes in lumbosacral angle,lumbar vertebra curvature and intervertebral space, and L_5S_1 was easier than L_(4,5) inthese structure changes.
4. Exercising abdominal muscles can not only establish a new banlance of lumbarvertebra,but improve the inflexion function.
