- What it is
- Boat-shaped bone of the proximal row on the thumb side, bridging both carpal rows.
- Function
- Proximal-row carpal: adapts its position as the wrist bends so the hand moves smoothly on the forearm.
- Size
- ≈ 11 × 19 × 11 mm
- Clinical note
- The most frequently fractured carpal bone; its blood supply enters distally, so the proximal pole can die (avascular necrosis).
