    The dorsal ramus of spinal nerve, posterior ramus of spinal nerve, or posterior primary division is the posterior division of a spinal nerve.The dorsal rami provide motor innervation to the deep (a.k.a. intrinsic or true) muscles of the back, and sensory innervation to the skin of the posterior portion of the head, neck and back.

    Neuroablation can be performed with chemical neurolysis or radiofrequency ablation. These techniques are often used on the medial branch nerves to treat low back pain and have been applied to the superior cluneal nerves. The use of phenol has been noted to relieve pain for up to 9 months but may not completely resolve symptoms. [5]

  4. Lumbar nerves - Wikipedia

    en.wikipedia.org/wiki/Lumbar_nerves

    The fifth lumbar spinal nerve 5 (L5) [5] originates from the spinal column from below the lumbar vertebra 5 (L5). L5 supplies many muscles, either directly or through nerves originating from L5. They are not innervated with L5 as single origin, but partly by L5 and partly by other spinal nerves. The muscles are: gluteus maximus muscle mainly S1

    The medial clunial nerves innervate the skin of the buttocks closest to the midline of the body. Those nerves arise from the posterior rami of spinal sacral nerves (S1, S2, and S3). Additional images

    en.wikipedia.org/wiki/Facet_joint

    In the thoracic and lumbar spine, the facet joints are innervated by the medial branch nerves from the vertebral segment above the upper segment and the upper segment. For example, the facet joint between T1 and T2 is innervated by C8 and T1 medial branch nerves. Facet joint between L1 and L2; the T12 and L1 medial branch nerves.

    Facet joint pain: Bogduk was among the first to recognize the role of facet joints as a source of spinal pain and contributed to the literature in anatomy, biomechanics, diagnosis, and therapeutics. He developed diagnostic and therapeutic techniques for facet joint pain, namely medial branch blocks and radiofrequency neurotomy.
