2. Joint complex Hip – ball and socket Closely associated the SIJ and lsp Movements – flex, ext, MR, LR, add and abd Joint is supplied from L3

3. Bones Femoral head 2/3 sphere fovea Acetabulum Covers 40% of head Neck of femur

4. Anterior Ligaments Capsule – complex, very thick and reinforced by : Iliofemoral ligament – –Y Pubofemoral ligament - triangular

5. Posterior Ligaments Ischiofemoral ligament – post Other ligaments Tranverse ligament –Crosses the acetabular notch Ligamentum Teres - intracapsular - attaches to fovea -contains blood vessel

6. Cartilage Hyaline cartilage- covers head of femur and acetabulum Labrum – fibrocartilage ring triangular in cross section, horse shoe shaped
