Elbow Fractures and Dislocation-Coronoid Fracture Patterns

Coronoid Fracture Patterns

Pdf Summary

This study examines the association between specific types of coronoid fractures and patterns of traumatic elbow instability. The researchers analyzed a series of patients with a fracture of the coronoid as part of an elbow fracture-dislocation. The results showed strong associations between certain types of coronoid fractures and patterns of elbow instability. Large coronoid fractures were strongly associated with anterior and posterior olecranon fracture-dislocations, while small transverse fractures were associated with terrible-triad injuries. Fractures of the anteromedial facet of the coronoid were associated with varus posteromedial rotational instability pattern injuries. The study suggests that an understanding of these associations can help guide the optimal management of these injuries. The study also highlights the limitations of the existing classification systems for coronoid fractures and proposes a new classification system based on fracture size and location. Overall, the study provides valuable insights into the relationship between coronoid fractures and patterns of elbow instability, which can help inform treatment decisions for these injuries.
