1. A system for determining structural integrity of a bone within the spine of a patient, the bone having a first aspect and a second aspect, said second aspect separated from said first aspect by a width and located adjacent to a spinal nerve, said system comprising:

  • a stimulator configured to generate an electrical stimulus to be applied to said first aspect of said bone;

    a monitor configured to electrically monitor a muscle myotome associated with said spinal nerve to detect if an onset neuro-muscular response occurs in response to the application of said electrical stimulus to said first aspect of said bone;

    an adjuster configured to automatically increase the magnitude of the electrical stimulus to until said onset neuro-muscular response is detected; and

    a communicator configured to communicate to a user via at least one of visual and audible means information representing the magnitude of the electrical stimulus which caused said onset neuro-muscular response.
