Adductor muscles are a group of muscles that originate from the pelvic bone and extend down to the inner thigh and knee. They are responsible for drawing the thigh closer to the body's central axis, a movement known as adduction. There are four primary adductor muscles: adductor longus, adductor brevis, adductor magnus, and gracilis. Adductor muscle strains are common injuries, particularly in athletes, and can result in groin pain.

The adductor muscle group
Adductors are a group of muscles that go from the pelvic bone down to the inner thigh and knee. The adductor muscles of the hip are a group of muscles in the medial compartment of the thigh that are primarily used for bringing the thighs together, a movement known as adduction. Adduction is the action of drawing a body part toward the median line of the body or toward the axis of an extremity.
The adductor group of thigh muscles occupies the medial myofascial compartment of the thigh. This group of muscles generally originates from the pelvis and inserts on the femur. The adductor magnus is the largest and most posterior of the medial thigh compartment muscles. It is a large triangular muscle with proximal tendinous attachments at the pubic bone's inferior ramus, ischial ramus, and ischial tuberosity. The adductor longus is a large, flat muscle that partially covers the adductor brevis and magnus, and forms the medial border of the femoral triangle. It provides some medial rotation. The adductor brevis is a short muscle that lies underneath the adductor longus. The gracilis is the most superficial and medial of the hip adductors. It crosses both the hip and knee joints, adducting the thigh at the hip and flexing the leg at the knee.
There are four primary muscles in the hip adductors group: adductor longus, adductor brevis, adductor magnus, and gracilis. The pectineus muscle is not a primary hip adductor but assists in the movement and also plays a role in hip flexion. All the hip adductors are innervated by the obturator nerve, which arises from the lumbar plexus. In closed-chain activation, the hip adductors help stabilize the pelvis and lower extremity during the stance phase of gait and assist in postural control.
Adductor strain is an injury to one of the adductor muscles and is one of the most common sports injuries. The adductor squeeze test is used in the diagnosis of groin injuries and for the measurement of adductor muscle strength.

Functions of the adductor muscle
The adductor muscles are a group of muscles that extend from the pelvic bone down to the inner thigh and knee. There are four primary adductor muscles: the adductor longus, adductor brevis, adductor magnus, and gracilis. The adductor minimus is often considered to be a part of the adductor magnus. The adductor longus is the most anteriorly placed muscle of the adductor group and is innervated by the obturator nerve. The adductor brevis is the shortest of the adductors and lies underneath the adductor longus. The adductor magnus is the largest muscle in the medial compartment and is the most commonly injured. The gracilis is the most superficial and medial of the hip adductors and crosses both the hip and knee joints.
The adductor muscles' primary function is to move the thigh/lower extremity closer to the body's central axis, a movement known as adduction. Adductor muscles also play a role in hip flexion and rotation. The adductor longus provides some medial rotation and contributes to the flexion of the extended thigh, as well as the extension of the flexed thigh. The adductor brevis has a role in the flexion of the hip, and some studies suggest it may also be involved in the external rotation of the thigh. The adductor magnus has two parts: the adductor portion and the hamstring portion. The adductor portion contributes to hip adduction and assists in hip extension, while the hamstring portion assists in knee flexion. The gracilis muscle is involved in hip adduction, hip flexion, knee flexion, and medial rotation of the knee.
The Pectineus muscle is often considered part of the hip adductor muscle group, although it has additional functions beyond hip adduction. It assists in hip adduction, hip flexion, and hip internal rotation. The obturator externus, gemelli (superior and inferior), and quadratus femoris may also be included in the group of hip adductors by some authorities.

Adductor magnus
The adductor magnus muscle is a composite muscle consisting of two parts: the adductor part and the ischiocondylar part. The adductor part, also known as the pubofemoral part, arises from the outer surface of the inferior pubic ramus of the pubic bone and the ischial ramus. It is functionally considered a muscle of the medial compartment of the thigh. The adductor part can be further divided into two portions: the superior portion, which arises from the pubic ramus, and the inferior portion, which arises from the ischial ramus. The superior portion of the adductor part passes obliquely and almost horizontally to insert at the upper part of the linea aspera. The ischiocondylar part of the adductor magnus forms a thick medial margin that descends almost vertically towards the lower end of the thigh. It ends in a rounded tendon and inserts at the adductor tubercle on the medial femoral condyle.
The adductor magnus is both a dynamic stabiliser of the pelvis and femur, as well as a prime mover of the femur into adduction. It plays a similar function to the deltoid muscle: one portion flexes the thigh and works as a medial rotator, while the other extends the thigh and is a lateral rotator. Both portions adduct the thigh. The anterior fibres, which originate from the rami of the pubis and ischium, may assist in flexion, while the posterior fibres that arise from the ischial tuberosity may assist in extension. The hip extension moment arm length of the adductor magnus changes with hip angle and it is a more effective hip extensor than either the hamstrings or gluteus maximus when the hip is flexed. The peak contractions of the muscle are seen in positions of hip flexion, for example, full squats.
The adductor magnus is in relation with several muscles and neurovascular structures. By its anterior surface, it is in relation with the pectineus, adductor brevis, adductor longus, femoral artery and vein, profunda artery and vein, and the posterior branches of the obturator artery, obturator vein, and obturator nerve. By its posterior surface, it is in relation with the semitendinosus, semimembranosus, biceps, and gluteus maximus muscle. By its inner border, it is in relation with the gracilis and sartorius muscles. By its upper border, it is in relation with the obturator externus and quadratus femoris.

Adductor longus
Adductors are a group of muscles that run from the pelvic bone down to the inner thigh and knee. Adductor muscles are mostly used for bringing the thighs together, a movement known as adduction. The adductor longus is a large, flat, fan-shaped muscle located in the medial aspect of the thigh. It is one of the adductor muscles of the medial thigh.
The adductor longus muscle plays a role in external/lateral rotation and flexion of the thigh. It also helps to stabilise the pelvis in a standing position and aids in balancing the body on the lower limb during walking. The adductor longus muscle is innervated by the anterior division of the obturator nerve (L2-L4). The obturator nerve is a branch of the lumbar plexus and descends medial to the psoas major muscle to enter the pelvis. The obturator nerve runs behind the common iliac vessels and lateral to the internal iliac artery and ureter.
The adductor longus is supplied by the anterior branch of the obturator nerve. The obturator nerve also supplies the adductor brevis and gracilis muscles. The adductor longus is in relation by its anterior surface with the pubic portion of the fascia lata, and near its insertion with the femoral artery and vein. By its posterior surface, it is in relation with the adductor brevis and adductor magnus, the anterior branches of the obturator artery, vein, and nerves, and near its insertion with the profunda artery and vein. By its outer border, it is in relation with the pectineus, and by the inner border with the gracilis.
Adductor tendinopathy is a common cause of medial leg and groin pain, especially among athletes. It is caused by a disproportionate strain on the muscles, often in combination with a poor warm-up and a lack of stretching.

Adductor brevis
Adductor muscles are a group of muscles that run from the pelvic bone down to the inner thigh and knee. Adductor brevis is one of the five primary hip adductor muscles, the others being adductor longus, adductor magnus, gracilis, and pectineus. Adductor brevis is a flat, triangular muscle found in the inner thigh, originating on the anterior surface of the pubis bone and inserting into the upper part of the linea aspera on the femur. This muscle is one of the shortest and weakest of the adductor group.
The adductor brevis muscle is responsible for pulling the leg medially when walking, helping to maintain balance and shift the centre of gravity onto the supporting foot. It also assists in external rotation and flexion of the hip, and stabilization of the pelvis while standing or walking. The muscle is innervated by the obturator nerve, which arises from the lumbar plexus.
Injuries to the adductor brevis muscle can result from various factors, including previous hip or groin injury, age, muscle fatigue, decreased range of motion, and inadequate stretching. Symptoms of an adductor brevis strain include pain extending to the inguinal and knee region when stretching and straining the muscles. Early assessment and treatment are crucial to prevent long-term athletic career implications. Treatment may include strengthening exercises for the muscles around the pelvis and core, as well as stretching routines following training sessions.
