[Biomechanics of the lumbar spine: a clinical approach].

The study of Biomechanics of the lumbar spine with clinical approach allows the physician related to locomotive sciences, to have a better interpretation of the clinical and radiological findings in order to carry out a treatment or a prediction of a medical problem with greater scientific foundation. The lumbar vertebral segment is studied from a biomechanical point of view in an integrated way, correlating with other body regions. The structures analyzed are the vertebrae, the intervertebral disks, the ligament and muscular system. The method of study goes from the static of the column to the dynamic, which includes the kinetic and kinematic aspects. The contradiction in the study of the lumbar spine is that the disorders of this body region are of the most frequent in the general and specialized medical consultation and, however, is not enough provided to the financial funds to carry out research.
