Iliocostal friction syndrome, also known as costoiliac impingement syndrome, is a condition in which the costal margin comes in contact with the iliac crest.The condition presents as low back pain which may radiate to other surrounding areas as a result of irritated nerve, tendon, and muscle structures.
Iliocostalis muscle has a common origin from the iliac crest, the sacrum, the thoracolumbar fascia, and the spinous processes of the vertebrae from T11 to L5. [1]Iliocostalis cervicis (cervicalis ascendens) arises from the angles of the third, fourth, fifth, and sixth ribs, and is inserted into the posterior tubercles of the transverse processes of the fourth, fifth, and sixth cervical vertebrae.
Twelfth rib syndrome, also known as rib tip syndrome, is a painful condition that occurs as a result of highly mobile floating ribs.It commonly presents as pain that may be felt in the lower back or lower abdominal region as a result of the 11th or 12th mobile rib irritating the surrounding tissues and nervous systems.
Dysfunction of the superior cluneal nerves lead to many different neuropathic symptoms such as burning pain, numbness, tingling, and dysesthesia around the low back and upper gluteal area. The most common symptoms are localized unilateral low back pain, though up to anywhere between 40 and 82% of patients may complain of leg symptoms – pain ...
The iliocostalis originates from the sacrum, erector spinae aponeurosis, and iliac crest. The iliocostalis has three different insertions according to the parts: iliocostalis lumborum has the lumbar part (where its insertion is in the 12th to 7th ribs). iliocostalis thoracis where its insertion runs from the last 6 ribs to the first 6 ribs.
The longissimus thoracis et lumborum is the intermediate and largest of the continuations of the erector spinae.. In the lumbar region (longissimus lumborum), where it is as yet blended with the iliocostalis, some of its fibers are attached to the whole length of the posterior surfaces of the transverse processes and the accessory processes of the lumbar vertebrae, and to the anterior layer of ...
The quadratus lumborum muscle originates by aponeurotic fibers into the iliolumbar ligament and the internal lip of the iliac crest for about 5 centimetres (2.0 in). It inserts from the lower border of the last rib for about half its length and by four small tendons from the apices of the transverse processes of the upper four lumbar vertebrae.
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.
