Abstract
Spinal instability has been assessed according to certain physiological or radio-graphic abnormalities of the spine [1–5]. A quantitative assessment of spinal instability is, however, essential for justification of lumbar fusion or stabilization and this has actually been conducted by few researchers [6] (D.C. Holmes, M.D. Brown, E.C. Eckstein, et al. 1989, In Vitro and In Vivo Measurement of Lumbar Spine Motion Segment Unit Stiffness; unpublished work, University of Miami School of Medicine). We attempted to develop a method of measuring spinal instability that could be carried out during lumbar spine surgery [7–10]. This method enabled us to measure the alterations of lumbar spinal instability in each step of surgical decompression, stabilization, or bone grafting. The final aim of this research was to establish an objective criterion for fusion and stabilization [6,11–14].
