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 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
pectineus is the only adductor muscle that is innervated by the
femoral nerve. The other adductor muscles are innervated by the
obturator nerve Variation In 33% of people a
supernumerary muscle is found between the adductor brevis and adductor 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
ontogenetically related to the adductors. ==Clinical significance==
