The iliofemoral ligament is a thick and very tough triangular capsular ligament of the hip joint situated anterior to this joint. It attaches superiorly at the inferior portion of the anterior inferior iliac spine and adjacent portion of the margin of the acetabulum ; it attaches inferiorly at the intertrochanteric line .
MR arthrography can also demonstrate ligamentum teres rupture or capsular laxity, which are debated causes of microinstability of the hip. Elongation of the capsule or injury to the iliofemoral ligament or labrum may be secondary to microtrauma in athletes.
Constant hip rotation places increased stress on the capsular tissue and damage to the iliofemoral ligament. This in turn causes hip rotational instability putting increased pressure on the labrum. [3] Traumatic injuries are most commonly seen in athletes who participate in contact or high-impact sports like football, soccer, or golf. [4]
The capsule of hip joint, articular capsule, or capsular ligament is strong and dense attachment of the hip joint.. Anterosuperiorly, it is attached to the margin of the acetabulum 5 to 6 mm. beyond the labrum behind; but in front, it is attached to the outer margin of the labrum, and, opposite to the notch where the margin of the cavity is deficient, it is connected to the transverse ligament ...
A teardrop-shaped lower portion gives origin to the iliofemoral ligament of the hip joint and borders the rim of the acetabulum. [ 1 ] Anteromedially and inferiorly to the AIIS is the iliopsoas groove , the passage for the iliopsoas muscle as it passes down to the lesser trochanter of the femur .
It has also been suggested that symptoms are caused by impingement of the iliotibial band in the knee during 30 degree flexion, which is a position common in running and cycling. [11] Additional proposed mechanisms causing the symptoms of ITBS include compression of the fat and soft tissues beneath the iliotibial band, and chronic iliotibial ...
The ischiofemoral ligament limits the internal rotation and adduction of the hip when it is in a flexed position. [3] Some deeper fibres of the ligament are continuous with the fibres of the zona orbicularis of the capsule. [4] This ligament is less well-defined than the other two capsular ligaments of the hip joint. [4]
The pubofemoral ligament is located anteriorly just underneath the iliofemoral ligament and serves primarily to resist abduction, extension, and some external rotation. Finally the ischiofemoral ligament on the posterior side of the capsule resists extension , adduction , and internal rotation .
