Abstract

Objective : To study the role of orientation and asymmetry of facet joints(tropism) whether it causes the herniation of intervertebral disc and direction of the herniation or not. Methods : the orientation of lumbar facet joints was studied with lumbar computed tomography(CT) in 315 subjects to determine if there is an association between facet tropism and herniation of intervertebral disc. We investigated frequency of tropism of L5-S1 in 315 subjects and tropism with disc herniation. Finally Authors studied relation tropism to direction fo disc herniation. Results : 1. Angle of facet joint is $48.93\pm7.34^{\circ}$ in Rhight and $50.3\pm9.99^{\circ}$ in Left Incidence of asymmetry of facet joints(tropism) was 32.6% 2. There is not significant association between tropism of L5-S1 and disc herniation. 3. There is not significant association between tropism of L5-S1 and direction of herniation. Conclusions : Statistically tropism of facet joints are not related to the frequency and direction of herniation of intervertebral disc.
