What do the cluneal nerves innervate?
What do the cluneal nerves innervate?
The superior cluneal nerves innervate the skin of the upper part of the buttocks. They are the terminal ends of lateral rami of the posterior rami of the lumbar spinal nerves (L1, 2, 3).
Why does my Cluneal nerve hurt?
Cluneal nerve irritation is usually caused by incorrect tilting of the pelvis from its original position and “kinking” of the nerves as they pass through their tissue tunnels. This can be the result of structural problems, such as spinal stenosis, failed back surgery, or slipped disc.
What is the function of the Cluneal nerve?
The superior and the middle cluneal nerves (SCN and MCN) are cutaneous nerves that are purely sensory. They dominate sensation in the lumbar area and the buttocks, and their entrapment around the iliac crest can elicit LBP.
Where is the Cluneal nerve located?
buttocks
The superior cluneal nerves innervate the skin of the upper part of the buttocks. They are the terminal ends of the T12-L3 spinal nerve posterior rami lateral branches….

Where do the Cluneal nerves come from?
The main anatomic consideration in the posterior approach is the cluneal nerves (Fig. 2-37). They arise from the posterior rami of L1-L3 and are responsible for sensation of the gluteal area. The medial branch of the superior cluneal nerve may be as close as 8 cm from the posterior superior iliac spine.
Where do the Cluneal nerves originate?
The superior cluneal nerve originates from the posterior rami of L1-2-3, then descends inferior to cross over the crest of the ilium in three branches. The medial branch travels through an osteofibrous tunnel which has been cited as a site of entrapment similar to carpal tunnel syndrome.
How long does a Cluneal nerve block last?
Pain in the area where the needle(s) was inserted. The pain can last for two to three days and can be treated by using ice and mild analgesics (pain medication) such as Motrin, Naprosyn or Tylenol.
Where does cluneal nerve come from?
The middle cluneal nerve is derived from the dorsal rami of S1-S3 and provides cutaneous innervations of the skin overlying the coccyx and the adjacent buttock. The inferior cluneal nerve is derived from the posterior femoral cutaneous nerve and innervates the inferior border of the gluteus maximus muscle.
What does Cluneal mean in Latin?
From Latin clunis (“rump, buttock”).
What does Cluneal mean?
the buttocks
[gloo´te-al] pertaining to the buttocks; called also natal and pygal.
How do you do a Cluneal nerve block?
Preparation for the cluneal nerve block procedure involves having a patient lie facedown on a table that is equipped with X-ray machinery. The skin is then sterilized and, if an intravenous anesthetic is necessary (an IV), it is set up along with a monitor that records vital signs.
Where does Cluneal nerve come from?
How is the cluneal nerve related to low back pain?
The relationship between the cluneal nerve and LBP (low back pain) has been well established in several areas of research that identify common areas of entrapment causing typical nerve pathologic features such as ischemia (lack of blood flow) and pain when compressed or palpated.
Where are the superior branches of the cluneal nerve located?
The Superior cluneal is located more superior (on top) along the iliac crest, and it a common area of entrapment and low back pain. Pain of these branches of the cluneal nerve are generally associated with standing and arching the back due to the L1-3 nerve roots origination.
What are the symptoms of superior cluneal nerve entrapment?
In addition, most patients with lumbar radiculopathy have back pain associated with reflex, motor, and sensory changes, whereas patients with superior cluneal nerve entrapment have no back pain and no motor or reflex changes.
Is there a relationship between the cluneal nerve and LBP?
The two main branches of cluneal nerves that identify the relationship between the cluneal nerve and LBP are the superior cluneal nerve, the middle cluneal nerves. The Superior cluneal is located more superior (on top) along the iliac crest, and it a common area of entrapment and low back pain.
