Anatomy

The Psoas Minor originates from the vertebral bodies of T12 and L1 and the intervertebral disc between them. It inserts into the pectineal line of the pubis and the iliopectineal eminence. The muscle is innervated by the lumbar plexus.

Function

The Psoas Minor acts as a weak flexor and external rotator of the hip joint. However, its functional significance is controversial due to its absence in a significant portion of the population.

Clinical Significance

The Psoas Minor is not typically associated with any specific clinical conditions. However, its absence can be used as a minor anatomical landmark in surgical procedures.
