다국어 초록 (Multilingual Abstract)

Objectives : One of the most important cause of spondylolisthesis is it's epidemiological structure and L5's stability takes a significant role. The purpose of this study is to assess the difference of the Tuffier's line among of Spondylolythesis patients. Methods : We analyzed the Anterior view of lumbar spine checked at erect position on 60 patients who had been diagnosed as spondylolythesis. We investigated the Tuffier's Line on X-ray film. Results and Conclusions : Age distribution was 15 to 66 and the average was 47.81. Men were 19 cases(31.6%) and women were 41 cases(68.4%). Compared to men, women were more exposed to spondylolisthesis and for the age distribution, 50's showed the biggest portion. Group of normal people showed proportion of 14.3% at L4, 44% at L4/5 and 41.7% at L5 each. And group of patients showed proportion of 48.4% at L4, 35% at L4/5 and 51.6% at L5 each. Comparing these results, significance probability was 0.004(<0.05) which was significant. As the results of comparing the relation between L4/5 and L5/S1 patients, Normal group showed average of 3.33 which were close to L4/5. When there are spondylolisthesis at L4/5, averege was 3.33, placed at lower part of the vertebra body. When there are spondylolisthesis at L5/S1, averege was 3.566, placed between lower part of the veterbra body of L4 and L4/5. The p value of Normal group and L4/5 spondylolisthesis patient group was 0.022(p<0.05) which was significant. But the p value of Normal group and L5/S1 spondylolisthesis patient group was 0.0239 which was not significant. Also p value of L4/5 spcndylolisthesis patient group and L5/S1 spondylolisthesis patient group was 0.721 which was also not significant.
