Adductor Longus

Introduction[edit|edit source]

Adductor longus is one of the adductor muscles of the medial thigh.^[1]Together withadductor brevis,adductor magnus,gracilisandobturator externus, it makes up thehip adductors.^[1]

This large fan-shaped muscle is situated most anteriorly of this group and covers the middle part ofadductor magnusand the anterior part ofadductor brevis.^[1]

The muscle forms the medial border of thefemoral triangle.

起源[edit|edit source]

Strong tendon from anterior aspect of pubic body inferior to pubic crest.^[1]

Insertion[edit|edit source]

Expands into a fan shape, attaching broadly to the linea aspera on the middle third of femur.^[1]

This insertion point is between the insertion of theadductor magnusand the origin ofvastus medialismuscle, and inferior to theadductor brevisinsertion.^[2]

Nerve[edit|edit source]

Anterior devision ofobturator nerve(L2,L3, L4).^[1]

Function[edit|edit source]

The main action of the adductor group of muscles is to adduct the thigh at the hip joint.

1. The adductor longus muscle also plays a role in external/lateral rotation and flexion of the thigh.
2. Along with the other hip adductors it helps to stabilize the pelvis in standing and aiding in balancing the body on the lower limb during walking.^[1][2]

Physiotherapy Relevance[edit|edit source]

Adductor Tendinopathyis a common cause of medial leg andgroin pain, especially among athletes. It is a common among injury in such sports as eg ice skating, horse riding, soccer, football, karate, running. Sudden changes in direction cause a quick adduction against a large abduction force thereby stressing the tendon, most commonly at its origin. It is caused by a disproportional strain of the muscles, often in combination with a poor warm-up and a lack ofstretching.^[3]

Assessment and Treatment[edit|edit source]

内收肌受伤是经常被忽视。一个早期ssessment is essential to prevent it becoming a career threatening injury for an athlete.

• It is essential to do a thorough assessment of the pelvis andcoreas well as the thigh muscles. Designing astrengtheningprogram to address which muscles are weak and which muscles are tight is vital. Treatment should include strengthening of the muscles around pelvis and core, along side with stretches to be completed following all training sessions.^[3]

• Manual muscle testing:^[4]

• Adductor squeeze test
