Study Notes
Hip Joint
- Ball-and-socket synovial joint
- Femoral head (ball) articulates with the acetabulum (socket)
- Connects axial skeleton to lower extremity
Hip Bone
- Fusion of ilium, ischium, and pubis
- Fusion occurs by the end of teenage years
- Two hip bones form the bony pelvis, along with the sacrum and coccyx
- Anteriorly united by the pubic symphysis
Femur
- Longest and heaviest bone in the body
- Superior end (head) articulates with the acetabulum
- Upper femoral epiphysis closes by 16 years of age
- Trabecular bone configuration follows Wolff's Law
- Principal compressive group, principal tensile group, greater trochanteric group, secondary tensile group, secondary compressive group, and Ward's triangle are all important structures
Superior End of Femur
- Head, neck, greater and lesser trochanters
- Head angled superomedially and slightly anteriorly when articulating with the acetabulum
- Attached to femoral shaft by the neck
- Neck angle of 130º (± 7º) to the shaft, decreases with age
- Greater trochanter is insertion site for gluteus medius and minimus
- Lesser trochanter is insertion site for iliopsoas
Acetabulum
- Formed by the fusion of ilium, ischium, and pubis
- Fusion complete by 20-25 years of age
Ilium
- Largest part of the hip bone
- Forms the superior part of the acetabulum
- Insertion point for gluteal muscles laterally and iliacus medially
- Anterior superior iliac spine (ASIS) and posterior superior iliac spine (PSIS) are important landmarks
Ischium
- Inferior aspect of the pelvis
- Forms the posteroinferior aspect of the acetabulum
- Ischial spine separates the greater sciatic notch from the lesser sciatic notch
