In human anatomy, the adductor muscles of the hip is a group of muscles of the thigh.

The adductor group is made up of:
The adductors originate on the pubis and ischium bones. and insert on the medial, posterior surface of the femur.
They are supplied by the obturator nerve.[1] except a small part of adductor magnus, that is innervated by tibial nerve.
In 33% of people a supernumerary muscle is found between the adductor brevis and minimus. When present, this muscle originates from the upper part of the inferior ramus of the pubis from where it runs downwards and laterally. In half of cases, it inserts into the anterior surface of the insertion aponeurosis of the adductor minimus. In the remaining cases, it is either inserted into the upper part of the pectineal line or the posterior part of the lesser trochanter. While similar to its neighbouring adductors, it is formed by separation from the superficial layer of the obturator externus, and is thus not ontogentically related to the adductors.[2]
So called adductor tenotomy (cutting the origin tendons of the adductor muscles of the thigh) and obturator neurectomy (cutting the anterior branch of the obturator nerve) is sometimes performed on children with cerebral palsy. These children often have a hypertonia of the adductor muscles, making abduction difficult, obstructing normal hip development, and putting them at risk of hip luxation.
