Psoas minor connects the T12-L1 to the pubic bone. L2-L5 and the sacrum are trapped between them. Psoas minor is strongly connected to the iliac fascia and seems to tense that fascia to support the activity of psoas. The pain pattern in “psoas minor syndrome” matches the area of the iliac fascia.
Origin – bodies of T12-L1
Insertion – the pectineal line of the pubic eminence, just medial to the belly of the iliopsoas
Function – assists in flexion of the lumbar curve
