7. Adductor Magnus
Origin:
- Adductor portion: Inferior ramus of the pubis and ramus of the ischium
- Hamstring portion: Ischial tuberosity
Insertion:
- Adductor portion: Gluteal tuberosity, linea aspera, and medial supracondylar ridge
- Hamstring portion: Adductor tubercle of the femur
Action:
- Adductor portion: Adducts the thigh and helps stabilize the hip
- Hamstring portion: Assists with hip extension
Innervation:
- Adductor portion: Obturator nerve (L2/3/4)
- Hamstring portion: Tibial division of the sciatic nerve (L4)

Needling
Position: Prone
Palpation: Palpate the medial posterior aspect of the thigh
Technique:
1. Make a shelf by compressing the adductor magus on the medial aspect of the thigh and needle perpendicularly in a posterior to anterior direction
2. Pick up this muscle in a pincher-type grip and needled in a similar fashion as above
Caution: Moderate – The femoral artery and vein passes through this muscle through the adductor hiatus and canal to exit posteriorly becoming the popliteal artery and vein (Needling in the proximal 1/3 of this muscle avoids these structures)

Note: There are specific needling techniques for pelvic health that will include levator ani, but these are not covered here
