Background
- Scaphoid fractures account for 70% of all carpal fractures
- Ulnar nerve damage associated with fractures of hamate or pisiform
- 50% of pisiform fracture associated with injury to distal radius or other carpal bone
- If bone fragment seen posterior to carpus on lateral, very likely triquetrum fracture
Fracture Types
Carpal fractures
- Scaphoid fracture
- Lunate fracture
- Triquetrum fracture
- Pisiform fracture
- Trapezium fracture
- Trapezoid fracture
- Capitate fracture
- Hamate fracture
Evaluation
- Evaluate Zone of Vulnerability (see picture)
Management
- Based on fracture location (see individual fracture page for details)
