Computer illustration of the psoas major muscle. The muscle attaches by slender fasciculi cranially to the medioventral surface of the T12 to L4 vertebral bodies and disk and caudally to the ventrocaudal borders of the lumbar transverse processes. The psoas major passes anterior to the SIJ caudally and anterior to the upper part of the hip joint. It inserts on the lesser trochanter of the femur together with the iliacus muscle to form the iliopsoas muscle. (Illustration created by author).
