Objectives : To investigate the relationship in acute lateral tortipelvis and breaks in low back pain patients with acute lateral tortipelvis were discussed. Methods : The subject of this study consisted of 43 patients who were diagnosed as acute lateral tortipelvis by X-ray and 23 patients who were diagnosed as none tortipelvis by X-ray. We investigated acute lateral tortipelvis and breaks on X-ray film. Results and Conclusions : In the distribution of acute lateral tortipelvis, L4 was 17 cases(39.5%), L3 was 14 cases(32.6%), L2 was 9 cases(18.6%), L1 was 4 cases(9.3%) in the sequence. In acute lateral tortipelvis group, the number of breaks was more than none tortipelvis group(p>0.05). The most common parity of breaks was L4-5 in low back pain patient. Between distribution of lumbar level of acute lateral tortipelvis and breaks, there was no significant relationship.
