Adductor Complex - Muscle Physiology & Functional Anatomy

Anatomy

Origin:

• Ischiopubic ramus (anterior, adductor portion)

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

Insertion:

• 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:

Physiology

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

Muscles Included

• Adductor Magnus

• Adductor Longus

• Adductor Brevis

• Gracilis

Antagonists:

• Gluteus Maximus
