ABSTRACT:
An apparatus for maintaining a desired spatial relationship between adjacent vertebrae and the sacrum includes a spinal plate which engages both the sacrum and vertebrae. The spinal plate is connected with the vetebrae and the sacrum by fastener assemblies. In order to enable a fastener assembly to engage the relatively thin sacrum, a fixture is connected with the spinal plate to enable the fastener which engages the sacrum to be skewed at an acute angle. The fixture has a mounting end portion which is slidably received in a slot in the spinal plate and a head end portion through which the fastener assembly extends.
