1. A system for performing a minimally invasive spinal stabilization procedure between two adjacent vertebrae of a subject, the system comprising:

  • a surgical robot mounted such that it defines at least one path for oblique screw insertion from the pedicle region in an inferior one of said two adjacent vertebrae into the body of the adjacent superior vertebra, towards its anterior cortical rim;

    a control system receiving three-dimensional preoperative data, including information regarding the spatial location of the bone structures and the nerve positions of said two adjacent vertebrae; and

    a registration system to relate the coordinate system of said surgical robot with said three-dimensional preoperative data,wherein said control system is adapted to use said information to determine a safe path for said oblique screw insertion, such that said spinal stabilization procedure can be performed by minimally invasive techniques without direct viewing of anatomical details of said vertebrae.
