The samples of spinal skeleton were measured on the basic width, the distance of two inferior lateral borders, lenth of the inferior process, the angle bewteen the inferior articular process and pedicle of lumbar vertebrae ranging from L1 to L5 of 100 adults.

Applied anatomic study on the placement of sacral screw through the five-seven o clock point on the articular facet of the superior articular process;

The investigation of the lamina on superior articular process in the thoracic and lumbar vertebrae and its clinical significance

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.
