  • J022021 Tensile Strength of Facet Joint Capsular Ligament Obtained from Porcine Cervical Spine

抄録

Whiplash Associated Disorder (WAD) in rear collision accident is difficult to recognize from X-ray images. However, recent clinical studies have mentioned that this injury occurs due to rupture on the cervical facet joint capsular ligament. In this study, porcine cervical facet joint capsule was subjected to axial quasi-static tensile loading to determine its strength at different loading rates and cervical segment location. Test specimens were obtained by dividing half-cut porcine cervical vertebrae into five cervical segments (C2-C3 to C6-C7) and cutting off all of the soft connective tissues, except the facet joint capsular ligaments. These specimens were fixed at both ends inside cup-like jigs filled with polyurethane resin, and were then subject to tensile loading on the axial direction of the vertebrae at three different loading rates (50, 250 and 500 mm/min) using a universal testing machine. Influence of loading rates and cervical segment locations on tensile strength and stiffness were found to be insignificant. Furthermore, tensile strength and stiffness of the porcine cervical facet joint capsular ligament were considered to be comparable with the cervical facet joint capsular ligament of human cadaver reported in other study. It indicates that porcine cervical facet joint capsular ligament is suitable for replacing human cervical facet joint capsular ligament during mechanical testing.
