Bone
Hip bone (os coxae)
Fused ilium, ischium and pubis forming one side of the pelvis
High-yield
The iliac crest forms the upper rim, the acetabulum receives the femoral head, and the ischial tuberosity supports seated weight. These landmarks belong to different regions of the same adult bone.
Overview
Each hip bone develops from three components that unite around the acetabulum. The paired hip bones connect with the sacrum behind and with each other in front, transmitting forces between the trunk and lower limbs.
Reference facts
- Bone type
- Composite pelvic bone with an irregular shape and broad plate-like regions
- Key landmarks
- Acetabulum; iliac crest and anterior superior iliac spine; ischial tuberosity and spine; pubic tubercle; greater and lesser sciatic notches; obturator foramen
- Articulations
- Femoral head at the hip joint, sacrum at the sacroiliac joint and opposite pubis at the pubic symphysis
Clinical correlation
The posterior iliac crest is a commonly used site for bone marrow sampling. The selected point and approach depend on the procedure and patient anatomy rather than one universal puncture location.
