Innervation to the facet joints vary between segments of the spinal, but they are generally innervated by medial branch nerves that come off the dorsal rami. It is thought that these nerves are for primary sensory input, though there is some evidence that they have some motor input local musculature.
Facet syndrome is a syndrome in which the facet joints (synovial diarthroses) cause painful symptoms. [1] In conjunction with degenerative disc disease , a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain.
Pain can be provoked by palpation of the facet joints, or the level can remain veiled, with only the referred pain as evidence of the defect. Usually unilateral, bilateral cases have been described as we present here. Patients will not have pain radiating below the knee, which is more typical of anterior ramus involvement.
Facet joint injections are used to alleviate symptoms of Facet syndrome. [1] The procedure is an outpatient surgery, so that the patient can go home on the same day. It usually takes 10–20 minutes, but may take up to 30 minutes if the patient needs an IV for relaxation. [2]
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 ...

They have been used for a variety of neuropathic conditions including facet joint pain. Nerve block injections specifically targeted at the superior cluneal nerves are limited. [ 5 ] However, these blocks are minimally invasive and involve injecting medications at the nerves as they cross the iliac crest. [ 11 ]
The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1] [2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the lamina and posterior ...
