Dysfunction of the superior cluneal nerves is often due to entrapment as the nerves cross the iliac crest – this can result in numbness, tingling or pain in the low back and upper buttocks region. Superior cluneal nerve dysfunction is a clinical diagnosis that can be supported by diagnostic nerve blocks. [1]
The superior cluneal nerves, middle cluneal nerves, posterior femoral cutaneous nerve, lateral femoral cutaneous nerve are all sensory and resection may simply be a more "complete" option, as nerve decompressions can't explore every part of the nerve and may miss some entrapment points.
The superior cluneal nerves travel through the thoracolumbar fascia and drape over the iliac crest. [5] The posterior branches of the iliohypogastric nerve can emerge on the surface above the iliac crest, with the nerve draping lower than usual in some individuals. [8]
Extensive scar tissue formation is a major cause of nerve entrapment, and for deep gluteal syndrome (entrapment of the sciatic nerve in the deep gluteal space), it's the most common cause. [11] While the concept of scar tissue causing traction injuries is widely accepted, [2] its role is more complex than strictly causing stretching injuries.
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
The cluneal nerves (or clunial nerves) are cutaneous nerves of the buttocks. They are often classified according to where on the buttocks they innervate. Specifically, the nerves are as follows: Superior cluneal nerves; Medial cluneal nerves; Inferior cluneal nerves
The lateral cutaneous branch ("iliac branch") pierces the internal oblique muscles and the external oblique muscles immediately above the iliac crest. [4] It is distributed to the skin of the gluteal region, behind the lateral cutaneous branch of the subcostal nerve; the size of this branch bears an inverse proportion to that of the lateral cutaneous branch of the subcostal nerve.
