The relationship of facet tropism to disc degeneration and disc herniation;

Result:Subjects with facet tropism had a significantly higher prevalence of lumbar lateral curvature.

Lumbar zygapophyseal joints asymmetry is the common anatomical abnormality in lumbar vertebra.

Facet joint asymmetry and lumbar intervertebral disc herniation in adolescent;

Purpose: To explore the method and probability for directly measuring the stress in lumbar facet joint and disc under dynamic loading, to afford the experimental base for further investigation of intra-articular stress changing regularity under different motion conditions.

Posterior facet joint excision is a relatively good nerve root decompression surgery.

Effects of Wallis Posterior Dynamic Stabilization System on the Range of Motion of Lumbar Spine and the Stress of Zygapophysial Joints

Objective To evaluate the technique and diagnosing value of MSCT curved planar reformation(CPR)in zygapophysial joints.

Results Zygapophysial joint fusion cage\'s construction was simple,it had the great contact area with articular surface and good stability after implantation.

Biomechanics of pressure changes in adjacent inferior zygapophyseal joint after artificial disc replacement

Objective: To study the relationship between sympathetic nerve and the branches of primary sensory neurons innervating cervical zygapophyseal joint,and to explore the mechanism of the external intervertebral foramens cervical nerve compression syndrome with neck shoulder pain and the symptom of head and face regions.

Two hundred and fifty-two cervical zygapophyseal joints in 22 cadavers were observed.
