Fascicle Orientation of Superficial Back Muscles Attached to the Posterior Layer of the Thoracolumbar Fascia: a Morphometric Study Using Human Cadavers

SUMMARY Background. The posterior layer of the thoracolumbar fascia (PTLF) connecting the trunk, upper and lower limb muscles is a part of the deep fascia of the back of the trunk. It is the major myofascial linkage for myofascial force transmission. The present study reveals the fascicle orientation of the muscles namely gluteus maximus, latissimus dorsi, and lower trapezius … Continued
