Under normal conditions, there is no<unk>  contact due to enough distance between the lower ribs and the iliac crest. Individuals with<unk>  may have their 10th, 11th, or 12th rib come in contact with the iliac crest. Structures of the body can be irritated as a result of<unk>  contact includes the nerves, tendons, and muscles surrounding the area. There are several nervous branches surrounding the iliac crest that may be impinged or irritated upon contact. The superior cluneal nerves travel through the thoracoumbar fascia and drape over the iliac crest. 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. Similarly, the ilioinguinal nerve runs below the iliohypogastric nerve, following just above the iliac crest. These nerves may be impinged or irritated as a result of the lower ribs coming in contact with the iliac crest.borderThe top of the iliac crest includes the attachments of the latissimus dorsi, the transversus abdominis, as well as the internal and external obliques. The quadratus lumborum also connects from the back tip of the iliac crest up to the 12th rib. These tendon and muscle structures surrounding the iliac crest are at risk for irritation due to<unk>  contact. Tendon irritation can result in referred pain, therefore affected individuals may experience pain throughout the hip, low back, the groin, chest, and thigh. This contributes towards the difficulty in diagnosis of<unk> .
