Hip Joint Anatomy

  Hip Joint Anatomy

Hip Joint is a ball and socket type of Synovial Joint. The hip joint is an articulation between the head of the femur and acetabulum of the pelvis bone. Joint stability is too good because of its anatomical features.  

Ligaments in Hip joint

    1.  Iliofemoral ligament – Between Ilium part of pelvis and femur bone

2.  

    2. Ischiofemoral ligament – Between Ischium part of pelvis and femur.

    3.  Pubofemoral ligament – Between Pubis part of pelvis and femur.

    4.  Ligamentum teres – Between Head of femur and acetabulum.

    5.  Transverse acetabular ligament - Small ligament connecting the articular cartilage edges.

Bursa around Hip Joint

    1.  Trochanteric bursa

    2.  Iliopsoas bursa

    3.  Gluteus Medius bursa

Movements in Hip Joint

    1.  Flexion

    2.  Extension

    3.  Abduction

    4.  Adduction

    5.  Internal Rotation

    6.  External Rotation

    7.  Circumduction

Joint Range of Motion:

    1.  Flexion – 110 to 120 degrees

    2.  Extension – 10 to 15 degrees

    3.  Abduction – 30 to 50 degrees

    4.  Adduction – 20 to 30 degrees

    5.  Internal Rotation – 30 to 40 degrees

    6.  External Rotation – 40 to 60 degrees

Muscles around the Hip Joint

    1.  Gluteus Maximus, Hamstring – Extensor of the Hip

    2.  Iliopsoas, Rectus femoris – Flexor of the Hip

    3.  Gluteus Medius – Abductor of the Hip

    4.  Gluteus Minus – Internal rotation and Abduction of the Hip

    5.  Adductor Longus and Brevis – Adductor of the Hip
