ABSTRACT:
A device for measuring angles of freedom of adjacent vertebrae which includes two reference elements associated with each vertebra respectively. Indicators are associated with the two reference elements for measuring the angle of freedom of movement of the vertebrae in torsion in a plane perpendicular to the longitudinal axis of the vertebrae and for measuring the angle of freedom of the vertebrae in lateral inflexion in a plane perpendicular to that of the spinous processes as a function of a given position of flexion-extension of the vertebrae in the plane containing the spinous processes.
