Adductor Magnus - Muscle Physiology & Functional Anatomy

Adductor Magnus





  • Ischiopubic ramus (anterior, adductor portion)

  • Lower outer quadrant of posterior surface of ischial tuberosity (posterior, hamstring or ischial fibers)


  • Lower gluteal line & linea aspera (anterior, adductor portion)

  • Adductor tubercle on the medial condyle ridge (posterior, hamstring or ischial fibers)

Major Artery:

  • Obturator artery


Neural Innervation:

  • Posterior division (L2-L4) of obturator nerve (anterior, adductor portion)

  • Tibial portion (L4-S3) of sciatic


Trigger Points:

Adductor Magnus Trigger Points   





Concentric Functions:

  • Hip adduction, transverse adduction & external rotation (during adduction)

  • Provides frontal plane stabilization during stance & assists in hip extension


Eccentric Functions:

  • Helps decelerates hip flexion at heel strike along with the other muscles of the adductor complex


Isometric Function:

  • Helps dynamically stabilize the lumbo-pelvic hip along with the other muscles of the adductor complex
