Objective: The superior cluneal nerve (SCN) may become entrapped where it pierces the thoracolumbar fascia over the iliac crest; this can cause low back pain (LBP) and referred pain radiating into the posterior thigh, calf, and occasionally the foot, producing the condition known as "pseudo-sciatica." Because the SCN was thought to be a cutaneous branch of the lumbar dorsal rami, originating from the dorsal roots of L1-L3, previous anatomical studies failed to explain why SCN causes "pseudo-sciatica". The purpose of the present anatomical study was to better elucidate the anatomy and improve the understanding of "pseudo-sciatica" from SCN entrapment. Read More
