Abstract

|
|
Objectives : The purpose of this study is to find out the relationship between hip internal rotation angle and the level of
herniation of lumbar intervertebral disc(HIVD) in single-segment.
Methods : We investigated 314 patients (158 male, 156 female) who were diagnosed as herniation of lumbar intervertebral
disc(HIVD) in single-segment. We measured 314 patients' hip internal rotation angle and analysed the relationship between
the hip internal rotation angle and the level of herniation of lumbar intervertebral disc(HIVD).
Results : 1. Among 314 cases, the hip internal rotation angle was different between male and female. Hip internal rotation
angle of male was mainly limited and that of female was mainly excessive. 2. Among 314 cases, the normal group, defined as patients who have specific range of hip internal rotation angle(male : 35˚ ±10˚, female : 45˚±10˚), tends to be occurred HIVD at L4/5 level. The limited group, defined as patients who have less angle than normal group, the excessive group, defined as patients who have more angle than normal group, and the complex group, defined as patients who have more angle of one leg and less angle of the other leg than normal group, tend to be occurred HIVD at L5/S1 level(p<0.05).
Conclusions : In single-segment lumbar HIVD patients, The normal hip internal rotation angle mainly leads to L4/5 HIVD,
while the limited and excessive hip internal rotation angle mainly lead to L5/S1 HIVD.
