Medial cluneal nerves

Medial Cluneal Nerves are a group of nerves located in the human body. They are branches of the posterior rami of the lumbar spinal nerves. They innervate the skin over the medial part of the buttock.

Anatomy

The Medial Cluneal Nerves originate from the posterior rami of the first three lumbar spinal nerves. They pass through the posterior part of the psoas major muscle, cross the iliac crest, and distribute to the skin of the buttock.

Function

The primary function of the Medial Cluneal Nerves is to provide sensory innervation to the skin over the medial part of the buttock. This includes the area around the coccyx and the sacrum.

Clinical Significance

Damage or irritation to the Medial Cluneal Nerves can result in a condition known as cluneal nerve entrapment. This condition can cause pain in the lower back, buttock, and leg. It is often misdiagnosed as sciatica.

Treatment

Treatment for cluneal nerve entrapment typically involves physical therapy, pain management, and in some cases, surgery to release the entrapped nerve.
