Özet
The erector spinae muscle in the dorsal part of the spine and the quadratus lumborum muscle in the anterior part maintain the stability of the lumbar region and lumbar lordosis. The psoas and iliacus muscles transfer the load of the spine from the lower back and pelvis to the thigh. An abnormal muscle bridge between the psoas and iliacus muscles can affect independent movement and the femoral nerve. In the training cadaver, it was observed that the medial half of the iliacus muscle in the pelvis originates from a higher level, from the fascia covering the quadratus lumborum muscle. A review of the literature showed that this part of the iliac muscle is a variant muscle and is called psoas quartus. The effect of the presence of this muscle on kinesiology was investigated. Reviewing the literature suggested that it may play a role in pelvic tilt.
