The facet joint between C7 and T1 is innervated by the C7 and C8 medial branch nerves. [citation needed] 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.
The dorsal ramus then turns to course posterior-ward before splitting into a medial branch and a lateral branch. Both these branches provide motor innervation to deep back muscles. In the neck and upper back, the medial branch is also responsible for providing sensory innervation of the skin; in the lower back, the lateral branch does so.
One branch sets off anteriorly to the groin or pubic region. A second branch remains posterior, innervating the lower back and upper gluteal region. Thirdly a lateral take-off passed down the anterolateral thigh or trochanter region. The term sclerotome, distinct from dermatome for anterior rami involvement, has been proposed to describe the ...
The third lumbar spinal nerve (L3) [3] originates from the spinal column from below the lumbar vertebra 3 (L3). L3 supplies many muscles, either directly or through nerves originating from L3. They may be innervated with L3 as single origin, or be innervated partly by L3 and partly by other spinal nerves.
Radiofrequency waves are used to produce heat on specifically identified nerves surrounding the facet joints called the lumbar medial branches of the dorsal ramus of the spinal nerves. [33] By generating heat around the nerve, the nerve is ablated, thus destroying its ability to transmit signals to the brain.
The lumbar and sacral plexuses innervate the pelvic girdle and lower limbs. Ventral rami, including the sinuvertebral nerve branches, also supply structures anterior to the facet joint, including the vertebral bodies, the discs and their ligaments, and joins other spinal nerves to form the lumbosacral plexus .
The meningeal branches of the spinal nerves (also known as recurrent meningeal nerves, sinuvertebral nerves, or recurrent nerves of Luschka) are a number of small nerves that branch from the segmental spinal nerve near the origin of the anterior and posterior rami, but before the rami communicans; rami communicantes are branches which communicate between the spinal nerves and the sympathetic ...
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]
