Computer simulation of lumbar flexion shows shear of the facet capsular ligament.

ABSTRACT:

Background context

The lumbar facet capsular ligament (FCL) is a posterior spinal ligament with a complex structure and kinematic profile. The FCL has a curved geometry, multiple attachment sites, and preferentially aligned collagen fiber bundles on the posterior surface that are innervated with mechanoreceptive nerve endings. Spinal flexion induces three-dimensional (3D) deformations, requiring the FCL to maintain significant tensile and shear loads. Previous works aimed to study 3D facet joint kinematics during flexion, but to our knowledge none have reported localized FCL surface deformations likely created by this complex structure.

Purpose

The purpose of this study was to elucidate local deformations of both the posterior and anterior surfaces of the lumbar FCL to under
