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.
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
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]
The different types of neurolysis include celiac plexus neurolysis, endoscopic ultrasound guided neurolysis, and lumbar sympathetic neurolysis. Chemodenervation and nerve blocks are also associated with neurolysis. Additionally, there is external neurolysis. Peripheral nerves move (glide) across bones and muscles.
The ilioinguinal nerve is a branch of the first lumbar nerve (L1). It separates from the first lumbar nerve along with the larger iliohypogastric nerve.It emerges from the lateral border of the psoas major just inferior to the iliohypogastric, and passes obliquely across the quadratus lumborum and iliacus.
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]
Nikolai Bogduk AM is a retired Australian anatomist, and emeritus professor of the University of Newcastle Bone & Joint Institute, Australia. [1] His research and publications were primarily on the anatomical sources and causes of chronic spinal pain and headache, as well as the development of new diagnostic techniques and treatments for these conditions.
The TESSYS method (transforaminal endoscopic surgical system) is a minimally-invasive, endoscopic spinal procedure for the treatment of a herniated disc.It was a further development of the YESS method by the Dutch Dr Thomas Hoogland in the Alpha Klinik in Munich in 1989 and was first called THESSYS (Thomas Hoogland EndoScopic SYStem).
