Objectives : The purpose of this study is to investigate the influence of hysterectomy on Low Back Pain(LBP) and to describe it through Oriental Medicine theory. Methods : Research was conducted by history taking of 1849 female LBP patients who visited Jaseng Oriental Medicine Hospital. Investigation was focused on the number of patients who underwent hysterectomy, and the length of time developing LBP after the surgery. Results : 178 patients(9.6%) underwent hysterectomy among 1849 patients, and it was higher than general rate of hysterectomy. In Oriental medicine, this result can be explained that it is caused by the lack of water function of spleen(腎水) from the absence of uterus, consequently it makes muscle weak and does harm to Blood and Meridian. Conclusions : History of hysterectomy has a significant influence on the development of LBP.
