Biomechanical normality model of the Human lumbar spine (Lumbosacral region)

Abstract

The Lumbo-Sacral Spine is a structure of the spine that supports one of the greatest burdens of the human body. It constitutes a biomechanical unit and is formed by 5 lumbar vertebrae distributed in such a way that each supports a weight. The Lumbo-Sacral Spine distributes a load and acts as a shock absorber for the spine thanks to its flexibility.The knowledge of the morphology of this spinal structure and its articulation with the first sacral vertebra is fundamental to determine the biomechanical behavior of the entire spinal column. Furthermore, it allows the study of its type of support, its stability and degree of cushioning, its mobility and, in short, all its cinematic and dynamic characteristics.
