What is the Torakolumbar fascia?

Thoracolumbar Fascia is a layer of soft tissue in the middle and lower part, to which many rear muscles are connected. Alternatively known as lumbodorsal fascia, it is found on the outside and between the deep muscles of the lower back, both surround and separate them. It creates three layers: front or deep layer, middle layer and rear or surface layer. It consists mostly of collagen and other elastic fibers, and not only stretches and divides muscles, but also the active connective tissue associated with the muscle to the bones of the pelvis, spine and thoracic hills. Neck to the bone ischium in the lower rear pan. If the skin and fat cover the back were removed to reveal the farthest layer of muscles, the diamond spot of the thoracolumbal fascia would be visible in the center of the lower back. It seems that the two sides of the large Latissimus dorsi muscle and two sides of the gluteus Maximus muscle form a large x, with thoracolumbal fascia as the penetration of these muscles in the center. This fascia stain covers the muscles of the erector spinae in the lumbar roundAsti and joins the edges of Ilium and ischium bone in the pelvis below.

Removing the superficial rear muscles-Lassimus dorsi on both sides of the center of the back and the trapezoidal muscle of the upper back-it indicates that thoracolumbal fascia as an erect spinae group extends upwards around the thoracic area of ​​the spine or in the rib. It crosses under the rear muscle Serratus, whose fibers the angle inward from the ninth to the twelfth ribs continues its ascent on both sides of the vertebral column. The tho layer of fascia then passes under the cosoche main and small muscles found between the shoulder blades before mixing with the fibers of the nuchal fascia of the neck.

under the muscles of Erector Spinae, which extends the spine backwards, is the middle layer of thoracolumbal fascia. This layer penetrates the rear muscles from both sides and separates the erector spinae group - muscles ilocostalis, longissimus and spinalis - from the muscle Quadratus lumborum. Quadratus lumborum runThe brown between the hip bones and the sides of the lumbar spine and bending the spine laterally or side and compressing or pulling down on the thoracic cage. Deep to the quadratus lumborum is a front layer of thoracolumbar fascia, which leads deep to or in front of this muscle and approaches the spine from both sides. Separates Quadratus lumborum from the main muscle of the front fuselage.

Thoracolumbar Fascia, though not Muscle, is considered to be important for the movements of the torso and hips. When it connects the muscles of the hips and legs with the unions of the rear and shoulder belts, for example by combining gluteus maximus, a powerful extensor of the hip and legs, with Latissimus dorsi, which attracts arms and shoulder blades, fascia transmits movement forces between these muscle groups. In other words, it contributes to the integration of movements in the upper and lower body, such as the help of glutes and Lats to download in combination during spine rotation.
