Manubrium of sternum (Manubrium sterni)

Layer: Bones

Educational content only — not medical advice.

Anatomy

The broad upper segment of the sternum: it joins both clavicles and the first ribs, and meets the sternal body at the sternal angle (of Ludwig) — the key landmark for counting ribs at the bedside.

Clinical notes

Manual compression of the manubrium is the core of standard CPR; fractures in frontal impacts extend posteriorly and threaten the ascending aorta and heart.
