The tailor's muscle (Latin sartorius), also called the longest thigh muscle, is the longest (about 50 cm) muscle of the human body. It extends from the ilium all the way to the proximal end of the tibia. In its course, it wraps like a tape around the front wall of the thigh, heading towards the medial part of the knee. It is thanks to him that a man puts his foot on his leg.

The tailor's muscle together with the quadriceps muscle (Latin quadriceps femoris) form the anterior group of the thigh muscles innervated by the femoral nerve (L2-L3). Tailoring pain is most often caused by overload and may radiate to other structures in the area of ​​the hip, thigh and lower leg.

Tailor's muscle - structure

The tailor's muscle starts from an attachment on theanterior superior iliac spine , then runs obliquely downwards medially, wrapping the front of the thigh to later turn back and reach to the medial epicondyle of the femur. From there it runs obliquely forward and, already as a flat, divergent tendon, attaches a littlebelow and medially to the tibial tuberosityand to theof the shin fascia . This tendon covers the attachments of the slender (Latin gracilis) and semitendinous (Latin semitendinosus) muscles, with which it fuses together to form the so-calledgoose foot .

The tailor traverses the front surface of the thigh in a furrow formed on one side by the quadriceps and on the other by the iliopsoas (Latin iliopsoas), and in the further course - by adductors. In its course, the tailor's artery accompanies the femoral artery, and the alignment of all structures is supported bywide fasciathat encompasses them.

Between the tendon and the tendon mm. for slender and semi-tendinous there issynovial bursa . It is often connected to the second synovial bursa, which lies between the tibia and the tibial collateral ligament and the mm tendon. slender and semi-tendon.

The vascularization of the tailor's m. Is due to the muscular branches leading directly from thefemoral arteryand its branches - the artery surrounding the lateral thigh and the descending artery of the knee.

Tailor's muscle - feature

The tailor's muscle is thetwo-joint muscleand the only muscle in the thigh that bends both the hip andknee.Bending the thigh ,turns awayeats as well and slightlyturns(rotates outwards).Bending the knee , slightlyturns the shin inwards .

The small thickness of the muscle, however, makes it quite weak. It is most pronounced with the flexion movement in the hip joint.

The tailor's muscle forms one of the armsof the femoral triangle(Latin trigonum femorale) - an anatomical area on the anteromedial area of ​​the thigh, the remaining "walls" of which are formed by the inguinal ligament and the outer edge adductor longus (Latin adductor longus). In the lower part of the femoral triangle is the femur, and in the upper part - the ethmoid fascia. Inside, however, there are: the neurovascular bundle, the femoral vein, the femoral artery and the femoral nerve, as well as a vertical and oblique chain of lymph nodes.

Tailor's muscle - pain

Tailoring pain is most common during the leg-to-leg movement, although it also happens that the area of ​​the attachments, and even the entire length of the muscle, is painful without assuming this position. The most common causes of tailoring pain are:

  • overload;
  • irritation;
  • over voltage.

Pain can radiate to other structures in the thigh as well as to the lower leg and even to the ankle. Proximal attachment pain may also be felt in the hip area and on the gluteus maximus muscle.

Tailor's muscle - exercises

The tailoring exercises involve bending the lower limb at the hip with resistance, because this is the main function of this muscle. All such exercises should be performed in accordance with the methodology or under the guidance of a specialist who will show and explain how not to hurt yourself.

In the case of tailoring, stretching is usually more important than strengthening. This muscle stretches, bringing the heel to the buttock, while the hip remains straight. This exercise can be performed both standing and lying down. The knees should be as close to each other as possible (preferably touching each other). Properly performed lunges and other postures in which the hip is extended are also effective. These exercises are especially recommended for people who lead a sedentary lifestyle or work in a sedentary position, because staying in this position for a long time not only shortens the tailoring function, but also promotes contraction of the femoral artery.
