Abstract
A spinal plate is provided that has two components of curvature in the lower surface that opposes the spinal vertebrae. This lower surface preferrably has the shape of a toroidal segment. A series of plates may be taken from a principal "s"-shaped template of similar shape on its lower surface. For convenience of manufacture, the shape of the curvature of the "S"-shaped template along the sides of the template is circular. A special hole pattern is also disclosed in respect of a tapered thoracic portion of the template.
