Introduction[edit | edit source]
The iliopsoas muscle complex is made up of three muscles that include the iliacus, psoas major and psoas minor.
The iliopsoas muscle is the strongest hip flexor and assists in external rotation of the femur, playing an important role in maintaining the strength and integrity of the hip joint. It is an important muscle in locomotion and upright posture, acting as a stabilizer of the lumbar spine and pelvis.[1]

The iliopsoas muscle complex is made up of three muscles that include the iliacus, psoas major and psoas minor
Origin: The iliopsoas muscle has its origin at the fusion of the psoas major and iliacus muscles. This fusion occurs at the level of L5-S2, and the combined muscles pass from the pelvis to the thigh under the inguinal ligament.
Insertion: The iliopsoas muscle inserts into the lesser trochanter of the femur via the psoas tendon. .
Bursa: The largest bursa of the hip joint is the iliopsoas bursa which is located deep to the iliopsoas musculotendionous junction and anterior to the hip joint capsule. The bursa has been reported to communicate with the hip joint in ~15% of patients.
Innervation: femoral nerve (iliacus part); direct branches of the lumbar plexus (psoas part)
Vascular supply: Iliolumbar artery & medial femoral circumflex artery.
Function: Flexor of the thigh and trunk; Assists in external rotation of the femur; Lateral flexor of the lower vertebral column[1]
