This article describes methods on measurement and analysis of spinal mobility during surgical operation for appropriate medical treatment. Because intraoperative spinal mobility is one of most useful concepts for definition of spinal instability which is not defined clearly. In this experiment, several porcine spines were used. Stiffness, neutral zone and residual load were derived from load-deformation curve. Spinal mobility is evaluated by Fourier descriptor from load-deformation curve, too. Fourier descriptor is useful for analysis of contour of hysteresis loop. 3D Movement of spine was analyzed by DLT from biplane video images. Both three parameters and Fourier descriptor were available for evaluation of spinal mobility.
