What is the function of the iliotibial band?
The purpose of the IT band is to transmit force from the glutes and TFL down the lateral thigh to the lower leg, thus providing support. IT band syndrome is an overuse injury that is derived from poor movement patterns and excessive tension on a supportive structure.
What is a iliotibial band anatomy?
The iliotibial tract, also known as the iliotibial band, is a thick strip of connective tissue connecting several muscles in the lateral thigh. It plays an important role in the movement of the thigh by connecting hip muscles to the tibia of the lower leg.
What is the action of the iliotibial tract?
This structure is sometimes called the iliotibial band or ITB. It’s primary action is to stabilize the hip and knee, though it also supports movements of the hip and knee through the action of the gluteus maximus and tensor fasciae latae muscles. Thickened fascial band located on the lateral aspect of the thigh.
Which muscles attach to the IT band?
The gluteal or buttock muscle fibers and the tensor fascia latae (muscles of the hip joint) attach to it, and the band acts to coordinate muscle function and stabilize the knee during running. Iliotibial band syndrome describes the pain caused by inflammation of the band as it crosses the lateral femoral epicondyle.
Where is the distal portion of the iliotibial band?
The ITB originates at the fascial components of the gluteus maximus, gluteus medius, and tensor fascia latae muscles and has distal attachments at the lateral border of the patella, lateral patellar retinaculum, and Gerdy’s tubercle.
What is the function of the tensor fasciae latae?
The main function of this muscle is to produce the extension and lateral rotation of the leg on the knee joint. Additionally, it contributes to the movements of the thigh, acting as a relatively weak abductor and medial rotator on the hip joint.
Where is the iliotibial band found in the body?
The IT band runs along the outside of the thigh, from just above the hip to just below the knee, and is made up of fascia, an elastic connective tissue found throughout the body.
Is iliotibial band a tendon or ligament?
The iliotibial band (ITB) is a tendon that runs along the outside of your leg. It connects from the top of your pelvic bone to just below your knee.
What nerve flexes the knee?
The sartorius is unique in that it flexes and laterally rotates the hip joint and flexes the knee, is innervated by the femoral nerve (L2 through L4), and receives blood supply by the muscular branches of the femoral artery.
Is iliotibial band a ligament?
The bottom of the IT band attaches to the top of the tibia (shinbone). One of its functions is to help stabilize the knee joint. Depending on where you look, sources define the iliotibial band as a large tendon, a ligament, or an area of thickened fascia.
Where is Gerdy’s tubercle?
proximal tibia
Gerdy’s tubercle was named after the French surgeon and anatomist Pierre Nicholas Gerdy’s. It is the insertion site of the iliotibial band and is located 2–3 cm lateral to the tibial tubercle on the proximal tibia.
Where can the distal insertion of the iliotibial band be palpated?
It descends along the lateral aspect of the thigh, between the layers of the superficial fascia, and inserts onto the lateral tibial plateau at a projection known as Gerdy’s tubercle.
