Chronic low back pain affects most adults at some point in their lives with, and has a prevalence of 20%-30%, representing the most common physical limitation in people younger than 45 years old. In a small percentage are able to obtain a definitive diagnosis. Low back pain is caused by sensitive structures of the spine (facet joints, spinal ligaments and paraspinal muscles. These anatomical structures are nerves that mediate pain (nociceptors), so alteration involved in the generation of the same. It is for therefore, the anatomical knowledge of the innervation of the lumbar spine, would contribute to a better diagnostic approach and treatment of various pain syndromes that occur in it. This review aims to describe the anatomical route from origin of nerve sinuvertebral Luschka and dorsal branch of spinal nerve as mains generators of LBP.
