Lumbar Facet

Changes in load transmission through facet and facet orientation have been considered as an important factor in intervertebral disc degeneration and osteoarthritic changes of the facet joint. (1)(2)(3) Facet joint surface area and orientation of the facets play key roles in load transmission. Their information is important for designing implants of the spine. They have been 2-dimentionally measured using CT and MRI. (4)(5) The purpose of the current study was to establish a three-dimensional (3D) technique for measuring lumbar facet joint area and orientation in vivo.

Joint Orientation

Facet joints are considered to play important roles in controlling spinal segmental motion and load transmission. It has been reported that 15–45% of low back pain is caused by facet joint diseases (1). Numerous studies on facet joint orientation have been reported in the literature; however, data on facet joint position is limited. Since the so-called “three-joint complex” is comprised of an intervertebral disc and two facet joints, it is important to determine the spatial relationship among these components to understand motion segment kinematics. Three-dimensional (3D) location of the facet joint may also provide important information for the studies on lumbar canal stenosis and spondylolisthesis. There has been no study, to our knowledge, to evaluate 3D position of the facet joint within the spine. The aim of this study was to determine accurately the facet joint position by using a subject-based computed tomography (CT) model and 3D measurement techniques, and analyze level, gender, ages and effects.
