Objectives : The purpose of this study is to find out the relationship between the hip in-ternal rotation angle and the site of herniation of single level lumbar intervertebral disc.
Methods : This study was carried out to 418 patients with lumbar disc herniation diag-nosed by M.R.I, who visited Bu-Chun Jaseng Hospital of Korean Medicine with low back pain. Researchers measured their hip internal rotation angle and analyzed the relationship between the hip internal rotation angle and the site of herniation of single level lumbar inter-vertebral disc.
Results : 1. Excessive right internal rotation of hip joint increases risk of L5/S1 HIVD. 2. Limited left internal rotation of hip joint decreases risk of L4/L5 HIVD. 3. In cases of L4/L5 HIVD level, there was evidence that the prevalence of HNP in men was 1.85 times as higher than that in women. 4. In cases of L5/S1 HIVD level, there was the evidence that the preva-lence of HNP in men was 0.64 times as lower than that in women.
Conclusions : In single-segment lumbar HIVD patients, limited left internal rotation of hip joint decreases risk of HIVD of L4/5 and excessive right internal rotation of hip joint mainly leads to L5/S1 HIVD.
