Clinical Features
- Tenderness along radial aspect augmented by applying pressure along index metacarpal
Imaging
- Difficult to visualize on x-ray; CT or MRI may be necessary
Differential Diagnosis
Carpal fractures
- Scaphoid fracture
- Lunate fracture
- Triquetrum fracture
- Pisiform fracture
- Trapezium fracture
- Trapezoid fracture
- Capitate fracture
- Hamate fracture
