Carpal fractures
Background
- Scaphoid fractures account for 70% of all carpal fractures
- Ulnar nerve damage associated with fractures of hamate or pisiform
- 50% of pisiform fx associated with injury to distal radius or other carpal bone
- If bone fragment seen posterior to carpus on lateral, very likely triquetrum fx
