The iliotibial tract or iliotibial band (ITB; also known as Maissiat's band or the IT band) is a longitudinal fibrous reinforcement of the fascia lata. The action of the muscles associated with the ITB ( tensor fasciae latae and some fibers of gluteus maximus ) flex, extend, abduct, and laterally and medially rotate the hip.
The transverse plane that includes each of the tubercles (one from the left iliac tubercle and one from the right iliac tubercle) is called the transtubercular plane. The origin of the iliotibial tract is the iliac tubercle. [1] The iliac tubercle is also the widest point of the iliac crest, and lies at the level of the L5 spinous process. [2]
The fascia lata is an investment for the whole of the thigh, but varies in thickness in different parts. It is thicker in the upper and lateral part of the thigh, where it receives a fibrous expansion from the gluteus maximus, and where the tensor fasciae latae is inserted between its layers; it is very thin behind and at the upper and medial part, where it covers the adductor muscles, and ...
The anterior superior iliac spine (ASIS) is a bony projection of the iliac bone, and an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis . It provides attachment for the inguinal ligament , and the sartorius muscle . [ 1 ]
Gerdy's tubercle is a lateral tubercle of the tibia, located where the iliotibial tract inserts. It was named after French surgeon Pierre Nicolas Gerdy (1797–1856).. Gerdy's tubercle is a smooth facet on the lateral aspect of the upper part of the tibia, just below the knee joint and adjacent to the proximal tibio-fibular joint, where the iliotibial tract runs down the outside part of the thigh.
The iliac tuberosity is part of the anatomy of the ilium portion of the hip bone. Behind the iliac fossa is a rough surface, divided into two portions, an anterior and a posterior. [ 1 ] The posterior portion, the iliac tuberosity , is elevated and rough, for the attachment of the posterior sacroiliac ligaments and for the origins of the ...
The iliac fascia (or Abernethy's fascia [citation needed]) is the fascia overlying the iliacus muscle. [1]Superiorly and laterally, the iliac fascia is attached to the inner aspect of the iliac crest; inferiorly and laterally, it extends into the thigh to unite with the femoral sheath; medially, it attaches to the periosteum of the ilium and iliopubic eminence near the linea terminalis, and ...
The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia's anterior surface, distal to the medial condyle. It creates a bony prominence just below the patella, and can be easily located with the fingers.
