摘要: Object Some centers report a lower incidence of vertebral artery (VA) injury with C-2 pars screws compared pedicle without sacrificing construct stability, despite biomechanical studies suggesting greater load failures screws. The authors reviewed published series describing and screw implantation atlantoaxial fusions the VA injury, malposition, successful fusion each type. Methods Online databases were searched for English-language articles between 1994 April 2011 clinical radiographic outcomes following posterior C-1 lateral mass either interarticularis or Thirty-three 2975 11 405 met inclusion criteria safety analysis. Seven 113 patients treated 20 918 w...
