Abstract
An adjustable trial for spinal implant sizing. The trial has a first and second plate that is adjustable between zero and degrees by use of continuously sloped edges that interface with a positioning band having reciprocal sloped edges.

A tool used to rotate the protrusions is marked with the angle of movement.
