APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The stability of the hip is provided by the joint capsule or acetabulum and the muscles and ligaments that surround and support the hip joint. The head of the femur rotates and glides within the acetabulum.

Detailed explanation-2: -The hip joint capsule is formed by three major ligaments: the iliofemoral, pubofemoral, and ischiofemoral ligaments. The capsular ligaments run in a spiral fashion preventing hip extension and are surrounded by thick longitudinal fibers that provide additional stability in the lateral plane.

Detailed explanation-3: -The pubofemoral ligament prevents excess abduction and extension, ischiofemoral prevents excess extension, and the iliofemoral prevents hyperextension.

Detailed explanation-4: -The capsule and ligaments provide passive stability to the hip joint but allow movements in different planes. The labrum of the hip is a fibrocartilaginous structure that is located at the level of the acetabulum. It provides added depth and stability to the joint.
