# Thoracolumbar Fascia

Notes

This layer of deep fascia extends from the sacrum to the neck and binds the erector spinae muscle to the postero-lateral surfaces of the vertebrae. It is very strong in the lumbar region where it is often referred to as lumbodorsal fascia. It consists of 3 layers which enclose the erector spinae and quadratus lumborum muscles and unite laterally to give origin to internal oblique, external oblique and transversus abdominis muscles.
