Thoracolumbar spinal anatomy.

Management of disorders affecting the thoracolumbar spine is predicated on a thorough study of normal anatomy combined with a complete understanding of the ways in which forces act on these anatomic structures (i.e., spinal biomechanics). In this article, the authors review the anatomy of the thoracolumbar spine relevant to the management of disorders affecting the region. This discussion of anatomy is not intended to be exhaustive or definitive but rather to serve as an introductory discussion to consideration of surgical approaches and issues of patient management.
