“…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.…”
