Slide2THE HIP JOINT
acetabulofemoral
jointclassified as an ‘enarthrodial’ (ball and socket)Acetabulum is formed by the three bones of the pelvis (ischium, pubis, ilium)It provides a deep socket for the femoral headLike the glenoid labrum, there is an acetabular labrum increasing the depth of the socket.
Slide3Ízesülő felszínekBall:head femur (hyalin cart)
Slide4Socket :acetabulum, facies lunata (hyalin cart.)
Slide5Additional componentacetabular labrum (fibrous cart.)Like the glenoid labrum, there is an acetabular labrum increasing the depth of the socket.
