Clinicals

Superior Cluneal Nerve Entrapment

The medial branch of the superior cluneal nerve passes over the iliac crest through a tunnel formed by the thoracolumbar fascia and the superior rim of the iliac crest. This branch of the superior cluneal nerve may become restricted in its osteofibrous tunnel against the iliac crest, just as osteofibrous tunnels affect other nerves, such as in carpal tunnel syndrome. Active release is a common treatment.
