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 ...
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 .
The joint itself is encompassed by a thick, fibrous joint capsule, which is lined by synovium. The ligaments that keep the hip joint in place are in fact, thickened areas of joint capsule, rather than distinct structures. The synovium generates fluid that lubricates the joint; in that fluid are the nutrients needed to keep the cartilage cells ...
The acetabular labrum (glenoidal labrum of the hip joint or cotyloid ligament in older texts) is a fibrocartilaginous ring [1] [2] [3] which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section (with the ...
The pelvic bone, also known as the innominate bone, is formed by three bones fused together: the ilium, ischium, and pubis. The musculature of the hip is divided into anterior hip muscles and posterior hip muscles. The major nerve supply that runs through the hip joint is the femoral nerve and the sciatic nerve. [16]
An intact labrum also helps to buttress the hip joint to distraction forces. [7] The labrum, when damaged, is also a pain generator, due to a large concentration of type II pain-associated free nerve endings found throughout the tissue, most pronounced at the labral base. [8] Hip joint, front view. The capsular ligament has been largely removed.
Transient synovitis of hip (also called toxic synovitis; see below for more synonyms) is a self-limiting condition in which there is an inflammation of the inner lining (the synovium) of the capsule of the hip joint. The term irritable hip refers to the syndrome of acute hip pain, joint stiffness, limp or non-weightbearing, indicative of an ...
