The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a complex,[1]: 1137 multilayer arrangement of fascial and aponeurotic layers forming a separation between the paraspinal muscles on one side, and the muscles of the posterior abdominal wall (quadratus lumborum, and psoas major[1]: 1137 ) on the other.[2][1]: 1137 It spans the length of the back, extending between the neck superiorly and the sacrum inferiorly.[3] It entails the fasciae and aponeuroses of the latissimus dorsi muscle, serratus posterior inferior muscle, abdominal internal oblique muscle, and transverse abdominal muscle.[4]
In the lumbar region, it is known as lumbar fascia and here consists of 3 layers (posterior, middle, and anterior) enclosing two muscular compartments. In the thoracic region, it consists of a single layer (an upward extension of the posterior layer of the lumbar fascia).[3] The thoracolumbar fascia is most prominent at its lower end[1]: 814–815 where its various layers fuse into a thick composite.[2]
