Background
- 2nd most common carpal bone injury
- Mechanism of injury
- Avulsion Fracture: Twisting motion of hand is suddenly resisted
- Body Fracture: Direct trauma (commonly accompanied by lunate/perilunate dislocations)
Clinical Features
- Localized tenderness over dorsum of wrist in area immediately distal to ulnar styloid
Imaging
- Lateral
- Best for seeing avulsion fx (tiny flake of bone on dorsum of triquetrum)
- PA
- Best for seeing nondisplaced fx
Management
- Avulsion fracture
- Wrist splint x1-2wks
- Body fracture
- Refer to orthopedist
- Stable: cast x 6wks
- Unstable (>1mm displacement): May require internal fixation
- Refer to orthopedist
