30:. It consists of three fascial layers - posterior, middle, and anterior - that enclose two (anterior and posterior) muscular compartments. The anterior and middle layers occur only in the lumbar region, whereas the posterior layer (as part of the thoracolumbar fascia) extends superiorly to the inferior part of the neck, and the inferiorly to the dorsal surface of the sacrum. The

It consists of a superficial lamina derived primarily from the latissimus dorsi and serratus posterior inferior, and a deeper lamina which forms a retinacular sheet encapsulating the paraspinal muscles. The posterior layer is attached to the spinous processes of lumbar and sacral vertebrae, and to the

In the thoracic region, the posterior layer (i.e. thoracic part of thoracolumbar fascia) attaches to the supraspinous ligament and spinous processes of all thoracic vertebrae, and to the costal angles of all ribs. It extends as far superiorly as the inferior part of the neck.
58:
The posterior layer and middle layer unite at the lateral margin of erector spinae, forming a though raphe; all three layers then unite at the lateral margin of quadratus lumborum, thus forming the aponeurotic origin of the transversus abdominis muscle.

At sacral levels, the posterior layer attaches to the posterior superior iliac spines, and posterior iliac crest, fuses with the underlying erector spinae muscle aponeurosis, and extends along the transverse tubercles of the sacrum.

The lumbar fascia binds the deep muscles of the back to the spine and to the transverse processes of the vertebrae. Additionally the lumbar fascia is an attachment for the
