0 a triangular muscle attached to the iliac fossa (= the large, smooth part of the pelvis) that allows the thigh to bend forward and turn
The iliacus originates on the iliac fossa on the interior side of the pelvis.
Of these, only iliacus is attached to the pelvis (the iliac fossa).
It is joined by the iliacus, psoas major forms the iliopsoas which is surrounded by the iliac fascia.
The iliacus originates on the iliac fossa to join psoas at the iliopubic eminence to form the iliopsoas which is inserted into the lesser trochanter.
The psoas is the primary hip flexor, assisted by the iliacus.
Pain on walking that confines the patient to bed indicates possible cancer adherence to or invasion of the iliacus muscle.
The iliacus originates on the iliac fossa of the ilium.
Though the iliopsoas is sometimes considered a member of the anterior compartment muscles, the iliacus and the psoas portions do not share the same innervation.
