The pullout strength had an effect on the stability of
\r\nplate screw fixation when inserted in the cervical spine. Nine
\r\ndifferent titanium alloy bone screws were used to test the pullout
\r\nstrength through finite element analysis. The result showed that the
\r\nMoss Miami I can bear the highest pullout force at 1,075 N, which
\r\ncauses the maximum von Mises stress at 858.87 MPa, a value over
\r\nthe yield strength of titanium. The bone screw should have large
\r\nouter diameter, core diameter and proximal root radius to increase the
\r\npullout strength.<\/p>\r\n","references":"[1] T.A. Mattei, M.S. Meneses, J.B. Milano and R.
