The psoas major is a multijoint muscle that spans from the thoracolumbar spine to the femur. Its proximal attachments are the anterolateral bodies of T12-L5 and the discs between, and the anterior surfaces of the transverse processes of L1-L5; its distal attachment is the lesser trochanter of the femur (Figure 1) (15).These two muscles cross the hip joint together and attach at the same point on the femur. The iliac and psoas major are the largest, strongest and most important of several muscles that control hip flexion, which makes the psoas the most important postural and structural muscle group in the body.Psoas can refer pain both in the low back and upper thigh areas, as indicated in bright red below. The patterns below show pain referred by a single Psoas muscle.
