The hip joint is a classical ball and socket type joint. Acetabulum is formed by the coalision of iliac, pubic and ischial bones. Acetabulum has an average of 20–40° anteversion and 40–50°inclination. Acetabulum is surrounded by the labrum. Labrum increases the articular surface and joint volume. The femoral head has 2/3 roundness of a sphere which is covered with hyaline cartilage. Femoral neck is located between the femoral head and body. Femoral neck anteversion angle is approximately 15–20° in adults and there is a 125±5° angulation between the femoral neck and shaft in the coronal plane. The hip is the second joint which has the widest range of motion after the shoulder joint. Twenty two muscles enable the movements of the hip joint. Joint stability is mainly provided by iliofemoral, pubofemoral and ischiofemoral ligaments. Medial circumflex femoral artery plays an important role on the blood supply to the femoral head. About 35° of flexion and 20° of extension of the hip joint is necessary during walking. The main loads imposed on the hip joint are abductor muscle strength and body weight.
