Hip structures include the following parts: bones, joints, ligaments, tendons and muscles. Hip bones have the femur (thighbone) and the pelvis. The femoral head is connected to the pelvis acetabulum.
Articular cartilage covers femur head and pelvis acetabulum. The hip cartilage is often very thick, and it can absorb shock and provide an smooth surface to make motion easier. The hip is surrounded by thick muscles, which provide further protection.
Hip ligaments (the soft tissues) are important, as they provide structural stability. Tendon is like iliotibial, used to connect muscles. If the tendon is too tight, hip problems often occur.
