The lateral cutaneous branch (iliac branch) pierces the Obliqui internus and externus immediately above the iliac crest and is distributed to the skin of the gluteal region behind the lateral cutaneous branch of the last thoracic nerve; the size of this branch bears an inverse proportion to that of the lateral cutaneous branch of the last thoracic nerve.When harvesting bone from the anterior iliac crest (AICBG) the lateral cutaneous branch of the Iliohypogastric nerve (L1) is most likely to be injured.This article incorporates text from a public domain edition of Gray’s Anatomy.
