| 1 | Bending | One cortex of the metaphysis fails due to tensile stress (Colles and Smith fractures), and the opposite cortex undergoes some comminution. |
| 2 | Shearing | Fracture of the joint surface: Barton's; reversed Barton's styloid process fracture, simple articular fracture. |
| 3 | Compression | Fracture of the surface of the joint with impaction of subchondral and metaphyseal bone (die-punch); intraarticular comminuted fracture. |
| 4 | Avulsion | Fracture of the ligament attachments to ulnar and radial styloid process; radiocarpal fracture-dislocation. |
| 5 | Combinations | Combination of types; High energy injuries. |
