The adductor muscles of the hip are a group of muscles in the
).Structure
The adductor group is made up of:
- Adductor brevis
- Adductor longus
- Adductor magnus
- Adductor minimus This is often considered to be a part of adductor magnus.
- pectineus
- gracilis
- Obturator externus[1] is also part of the medial compartment of thigh
The adductors originate on the pubis and ischium bones and insert mainly on the medial posterior surface of the femur.

Nerve supply
The
adductor magnus which is innervated by the tibial nerve.[4]
Variation
In 33% of people a
obturator externus, and is thus not ontogenetically related to the adductors.[5]
