Fracture of olecranon - Colton classification
Colton classification was the first classification of olecranon fractures. It divides them according to displacement of fragments into two types. Displaced fractures are further divided into four subtypes.
| Type | Description |

| Undisplaced and stable | displacement <2mm, displacement does not increase with elbow flexion |
| Displaced | A) avulsion fracture B) oblique or transverse fracture C) comminuted fracture D) fracture with dislocation in the elbow joint |
