Introduction
- Large triangular muscle located in the medial compartment of the thigh
- Primarily an adductor muscle, also contributes to some flexion and extension
Origin
- Superior segment: ramus of the pubis
- Inferior segment: ramus of the ischium [6]
Insertion
- Superior segment: medial gluteal tuberosity (medial to the Gluteus Maximus)
- Inferior segment: linea aspera and proximal medial supracondylar line of the femur [6] [7]
Actions
- Adductor portion
- Adduction of the thigh
- Flexion of the thigh
- Hamstring Portion
- Adduction of the thigh
- Extension of the thigh
- Both portions work together during the gait cycle and control the pelvis
Vascular
- Primary source: Perforating branches of the profunda femoris artery
- Superior portion: medial femoral circumflex
- Inferior portion: popliteal and genicular arteries
- Other arteries: Obturator artery
Nerve
- Posterior branch of the obturator nerve
- Tibial portion of the sciatic nerve [7]
- Adductor magnus forms part of the posterior border of Adductor Canal along with adductor longus
