Detecting Facet Capsular Ligament Injury during Tension using Collagen Fiber Realignment

The objective of this study was to develop a methodology to identify microstructural tissue damage in the human cervical facet capsule via collagen fiber realignment during tensile loading. Tensile loading of the cervical facet capsule induces collagen fiber disorganization, nociceptor activation, and persistent pain in the absence of tissue rupture. However, conventional imaging techniques, such as computed tomography or magnetic resonance imaging, are not able to identify the less severe tissue damage that can be sustained by the facet capsule during whiplash. Similarly, injury biomechanics studies have been focused primarily on defining responses at mechanical failure, where tissue rupture is overtly detectable by visual inspection. However, detecting the initiation of mechanical damage in the facet capsule is needed to begin to develop physiologically relevant injury tolerances for this ligament.
