Summary of Muscles in the Femoral Triangle

Anterior Thigh Sartorius Origin Anterior superior iliac spine Insertion Superior aspect medial surface of tibial shaft Action Flexes, adducts and laterally rotates the hip joint and flexes the knee Nerve Supply Anterior division of femoral nerve (L 3, L 4) Blood Supply Femoral artery

Hip Flexors Iliacus Insertion Upper 2/3 of iliac fossa of ilium, lateral aspect of sacrum Action Lesser trochanter inferior aspect Origin Nerve Supply Flexes and medially rotates hip Blood Supply Muscular branch of femoral nerve (L 2, L 3) Lumbar branch of iliopsoas branch of internal iliac artery

Hip Flexors Psoas Insertion Anterior surfaces and lower borders of transverse processes of L 1 - L 5 and bodies and discs of T 12 - L 5 Action Lesser trochanter Nerve Supply Flexes and medially rotates the hip Blood Supply Anterior primary rami L 1, 2 Origin Lumbar branch of iliopsoas branch of internal iliac artery

Anterior Thigh Pectineus Origin Pectineal surface of the pubis Insertion Pectineal line of femur below lesser trochanter Action Adducts the thigh, flexes hip joint Femoral nerve & some innervation from the obturator nerve (L 2, L 3, L 4) Nerve Supply Blood Supply Medial circumflex femoral branch of femoral artery and obturator artery

Anterior Thigh Origin Adductor Anterior surface of body of Longus Insertion Action Nerve Supply Blood Supply pubis, just lateral to pubic symphysis Middle third of linea aspera, between the more lateral adductor magnus and brevis insertions and the more medial origin of the vastus medialis Adducts, flexes and medially rotates the hip joint Anterior division of obturator nerve (L 2, L 3, L 4) Obturator artery and medial circumflex femoral artery
