Bone
Scaphoid
Boat-shaped carpal bone
High-yield
Most fractured carpal bone; snuffbox tenderness. Retrograde blood supply risks avascular necrosis of the proximal pole.
Overview
The largest bone of the proximal carpal row, spanning both rows and forming the floor of the anatomical snuffbox. It is the most commonly fractured carpal bone.
Reference facts
- Bone type
- Short (carpal)
- Key landmarks
- Tubercle of scaphoid; Proximal and distal poles; Waist
- Articulations
- Radius; Lunate; Capitate; Trapezium; Trapezoid
Clinical correlation
Scaphoid fracture may show avascular necrosis or non-union because its blood supply enters distally.
