Sartorius muscle ilium, the ilio-pectineal line or the pubis. The muscle may be split into two parts, and one part may be inserted into the fascia lata, the femur, the ligament of the patella or the tendon of the semitendinosus. The tendon of insertion may end in the fascia lata, the capsule of the knee-joint, or the fascia of the leg. The muscle may be absent in some people. The sartorius muscle can move the hip joint and the knee joint, but all of its actions are weak, making it a synergist muscle. At the hip, it can flex, weakly abduct, and
Ultrasonography of chronic venous insufficiency of the legs 1/3 of the thigh. It can also but rarely, drain in the vein of the semimembranosus (thigh muscle) (shown below). Usually though, it connects with a perforator vein at its middle 1/3. To check for insufficiency, the Paraná maneuver is very useful. The Giacomini vein mostly acts as a bypass between the GSV and SSV territories. Usually its flow is in the normal anterograde direction, from bottom to top. However it can become retrograde without pathology. For example, after a GSV stripping, laser ablation or after its ligation at the sapheno-femoral junction, the Giacomini vein will drain into the SSV,
