FAQ
Frequently Asked Questions
The capitate bone is one specific type of carpal bone. 'Carpal bones' is the collective term for the eight small bones of the wrist, one of which is the capitate.
Yes, with some difficulty. It is located in the centre of the wrist on the dorsal (back) side, and can be felt when the wrist is flexed, though it is surrounded by other bones and tendons.
It comes from the Latin 'caput', meaning 'head', due to its large, rounded, head-like shape.
No, isolated fractures of the capitate are relatively uncommon compared to other carpal bones like the scaphoid. They usually occur in high-impact injuries or in combination with other wrist injuries.
