Fig. 7From: Mechanical performance of porous biomimetic intervertebral body fusion devices: an in vitro biomechanical studyFailure modes of different mechanical tests. Static axial compression usually resulted in buckling of the portion of the device not shielded by the fixture blocks. Static compression-shear usually resulted in plastic deformation of the device in the direction shear force was applied. The failure mode during subsidence testing consisted of the device sinking into the polyurethane foam test block, with no structural failures of the cervical interbody fusion devices reportedBack to article page
