The psoas minor is a long, slender muscle that is placed (when present) in front of the psoas major muscle. It is absent in 40% of individuals.^[1]

It arises from the sides of the bodies of the twelfth thoracic and first lumbar vertebrae and from the intervertebral discs separating them. It ends in a long flat tendon which is inserted into the pectineal line and iliopectineal eminence, and, by its lateral border, into the iliac fascia.
