The document details the hip adduction muscles, highlighting their origins, insertions, nerve and blood supply, and actions. Key muscles include the pectineus, adductor longus, gracilis, adductor brevis, and adductor magnus, each contributing to thigh adduction and rotation at the hip joint. It emphasizes the roles of these muscles in both medial and lateral rotation of the thigh.

2. Hip Adduction:
Hip adduction is the movement of
bringing the thigh towards the
midline of the body. This
movement is primarily controlled
by the hip adductor muscles

3. Primary Hip Adductors
● Pectineus
● Adductor longus
● Gracilis
● Adductor brevis
● Adductor magnus—both heads

4. Pectineus:
Origin: Pectineal line of the pubis.
Insertion: Pectineal line of the femur
just below the lesser trochanter.
Nerve Supply: Obturator nerve (L2-L4).
Blood Supply: Branches of the obturator artery.
Action: Adducts and flexes the thigh at the
hip joint; assists in medial rotation of the thigh.

5. Adductor longus:
Origin: Pubic bone, near the pubic symphysis.
Insertion: Middle third of the linea aspera of the
femur.
Nerve Supply: Obturator nerve (L2-L4).
Blood Supply: Branches of the obturator artery.
Action: Adducts and flexes the thigh at the hip joint.

6. Gracilis:
Origin: Pubic symphysis.
Insertion: Medial surface of the tibia, just below the medial condyle.
Nerve Supply: Obturator nerve (anterior division) and branches of the
tibial nerve (L4-S3).
Blood Supply: Branches of the medial circumflex femoral artery and
the obturator artery.
Action: Adducts the thigh, flexes and medially rotates the leg at the
knee joint.

7. Gracilis:

8. Adductor brevis:
Origin: Inferior ramus of the pubis.
Insertion: Pectineal line and linea aspera of the
femur.
Nerve Supply: Obturator nerve (L2-L4).
Blood Supply: Branches of the obturator
artery.
Action: Adducts and flexes the thigh, assists in
medial rotation of the thigh. Youtube link:

9. Adductor magnus—both heads:
Origin: Inferior ramus of the pubis, ischial tuberosity, and ischial
ramus.
Insertion: Linea aspera and adductor tubercle of the femur.
Nerve Supply: Obturator nerve (anterior division) and tibial portion of
the sciatic nerve (L2-S1).
Blood Supply: Branches of the femoral artery (medial circumflex
femoral, deep femoral, and obturator arteries).
Action: Adducts, extends, and flexes the thigh at the hip joint; assists
in medial rotation.

11. Role of Hip Adductor Muscles in Thigh Adduction
and Rotation:
Adductor Magnus:
● Medial Rotation: When the hip is flexed, the anterior fibers of
adductor magnus assist in medial rotation of the thigh.
● Lateral Rotation: The posterior fibers of adductor magnus
assist in lateral rotation of the thigh when the hip is extended.
Gracilis: Medial Rotation: Gracilis helps in medial rotation of the
thigh when the hip is flexed.
Pectineus: Medial Rotation: Pectineus also contributes to medial
rotation of the thigh when the hip is flexed.
