Adductor+Longus

toc =Description: = Adductor Longus forms part of the hip adductor group and it is the most superficial muscle of the three muscles in the adductor group. Adductor Longus is located in the medial compartment of the thigh. It is a long triangular shaped muscle with its apex at the pubis. Its fibres run obliquely from the pubic bone to the femur. Adductor longus originates at the anterior part of the pubis near the pubic crest and symphysis. It inserts into the upper two thirds of the linea aspera of the femur along the medial lip. Its main actions are to adduct as well as to flex the hip joint but it is also said to assist in medial and lateral rotation of the hip. The nerve that supplies adductor longus is the obturator nerve which arises from L2 and L3 (Lumbar spine). Adductor Longus gets its blood supply from the obturator artery, the medial circumflex femoral artery, the femoral artery as well as direct branches and perforating branches of the deep femoral artery.

=Interactions and relations to other Muscles: = Adductor longus forms part of the hip adductor group (medial compartment of the thigh) along with pectineus, adductor brevis, gracilis and adductor Magnus, thus these muscles are agonists . Adductor longus is the most superficial muscle of the five adductor muscles and it lies inferior to adductor brevis and superior to adductor magnus. The actions of adductor longus are hip adduction, assists with hip flexion. The antagonists of adductor longus would thus be the hip abductor group (gluteus medius, gluteus minimus, gluteus maximus, tensor fasciae latae, obturator internus, gemellus superior, gemellus inferior and piriformis) as well as the hip extensor group (semimembranosus, semitendinosus, biceps femoris and gluteus maximus)

=Relevance to Physiotherapy: = Adductor longus is relevant to physiotherapy with regards to femoral fractures and groin strain. A femoral fracture is the fracture of the femur which this leads to weakening of the muscles which surrounds the femur. The adductor longus is one of the muscles which can be affected. Once the fracture has healed, the physiotherapist’s job is to strengthen these muscles by using strengthening exercises. Groin strain is the tearing of some or all of the hip adductor muscles. Physiotherapy is then relevant to assist the healing process of the groin strain and also to ensure that the risk of future fractures is reduced. Treatment of groin strain includes soft tissue massage, electrotherapy, stretches and much more.
