Abstract

This biomechanical study investigates the efficiency of a new procedure of destabilization at the L4/L5 spinal unit, as well as the effect of a new system to stabilize it. The instability is effective in backward-forward and in lateral bending (p < 0.05), and the neutral zone is increased in backward-forward and in axial rotation (p < 0.05). The artificial ligament and its wedge stabilize the cut spine, and is effective in backward-forward and in lateral bending (p < 0.05).
