Anatomical – morphological characteristics of the acetabulum
The acetabulum forms the pelvic bones, together with the head of the femur forms the hip joint, which is the link between the upper part of the body and the lower extremities. The morphology of the acetabulum determines and influences the quality and function of the hip joint. All anatomical and morphological changes of the acetabulum directly affect the development of many diseases of the hip joint. Its anatomical structure and morphological orientation play a major role in the transfer of body weight through the femur to the foot. The acetabulum labrum has the role of increasing the surface of the acetabulum, increasing its depth, reducing contact stress, and preventing direct contact between the acetabulum cartilage and the femoral head.
