The iliotibial tract may be irritated where it passes over the anterior superior iliac spine in iliotibial band syndrome. [3] The line around anterior superior iliac spine is sometimes called the panty line or "bikini line". [8] It is considered to be a "discreet" location for concealing cosmetic surgery scars and ports. [9]
The iliac tubercle is located approximately 5 cm (2 in) posterior to the anterior superior iliac spine on the iliac crest in humans. [1] 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.
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 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.
Surgery typically involves removal of a small piece of the iliotibial band to release excessive tension. Other procedures that have been utilized include resection of the iliotibial band bursa and z-lengthening. In the z-lengthening procedure, two horizontal incisions are made in the band and connected by a vertical incision, forming a z.
If the tibia's position on the femur reduces as the knee is flexed in the range of 30 to 40 degrees or if there is an anterior subluxation felt during extension the test is positive for instability. Pivot-shift is not straightforward to perform. For many with instability, the reproduction of instability is unpleasant and 'visceral'.
It is inserted between the two layers of the iliotibial tract of the fascia lata about the junction of the middle and upper thirds of the thigh. The tensor fasciae latae tautens the iliotibial tract and braces the knee, especially when the opposite foot is lifted. [1] The terminal insertion point lies on the lateral condyle of the tibia. [2]
Surgery is often considered a last resort, but for some patients, it is the only method of effectively stabilizing the loose joint. A fixation of the joint (screws or similar hardware only, without the use of bone grafting ) is more common than a spinal fusion , as it is much less invasive, surgically straightforward, and results in a quicker ...
