“…In human spines, load transmission via the facets varies with the direction of movement (Ianuzzi et al, 2004;Chang et al, 2007;Olsewski et al, 1994). Given the increased clinical use of motionsparing implants (e.g., artificial intervertebral disks), an accurate method for determining load transmission via the facets is an important consideration in experimental spinal biomechanics.…”

“…Nesse sentido, a tendência da não consolidação foi observada quando a altura primária do disco intervertebral foi aumentada em mais do que 4mm (15) . A altura excessiva do enxerto ósseo aumenta o risco da fratura do enxerto ou da placa vertebral terminal, o que pode resultar em afundamento do enxerto (15)(16)20) . Por outro lado, a utilização de enxerto com pequena altura pode não restaurar a lordose cervical (16) .…”

“…57 To prevent fracturing of the ProOsteon 200 implant, Thalgott et al 52 emphasized the need for careful graft handling and shaping, rigid plate fixation, and maximal bone-implant contact area to minimize excess or asymmetric loading. The normal compressive load in the anterior cervical spine is estimated to range from 12 to 90 N, 34,38,55 and increases with increased flexion loading. 38,55 Anterior cervical plates increase biomechanical rigidity, reduce the rate of graft collapse, maintain alignment, and increase fusion rates after interbody grafting.…”
