Hip joint capsule

Anatomy

Strong and dense capsular ligament, which provides support to the hip joint. Attaches superiorly to margin of the acetabulum, and anteriorly to the outer margin of the labrum. It consists of both circular and longitudinal fibers, which are thicker superiorly and anteriorly, where most support is needed.

Functions

Gives general support to the hip joint, along with the extra-capsular ligaments.

Clinical

Hip capsule contracture occurs where the fibrous capsule tightens and thickens, making the joint less mobile. It may be caused by arthritis or long-term disuse.
