The hip anatomy
The hip is a ball-socket joint and is formed by the head of the femur and the acetabulum (located in the lateral region of the pelvis and formed by the fusion of the pubis, ischium and iliac) and covered by hyaline articular cartilage in the shape of a cell. It has a fibrocartilage ring with the role of increasing the depth of the acetabulum (socket) called the acetabular lip (Figure 1).The head of the femur is the most proximal portion of thefemur, has a hemispherical (convex) shape, and is connected to the neck of the femur (between the greater and lesser trochanters). The neck of the femur guides the head of the femur at an inclination of approximately 125º in the medial, superior, and anterior direction.
