摘要

Characterization of olecranon fracture types. a Type I, longitudinal or transverse compression; b type II, olecranon avulsion fracture; c type III, transverse proximal to coronoid process; d type IV, oblique through coronoid process; e type V, coronal fracture; and f type VI, comminuted fractures (degree of displacement: 0, displacement less than one third ulnar width; 1, between one third and two thirds; 2, over two thirds of ulna)
