The management of multiple fractures in one upper extremity: a case report

Are classifications of proximal radius fractures reproducible?

Background

Fractures of the proximal radius need to be classified in an appropriate and reproducible manner. The aim of this study was to assess the reliability of the three most widely used classification systems.

Methods

Elbow radiographs images of patients with proximal radius fractures were classified according to Mason, Morrey, and Arbeitsgemeinschaft für osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) classifications by four observers with different experience with this subject to assess their intra- and inter-observer agreement. Each observer analyzed the images on three different occasions on a computer with numerical sequence randomly altered.

Results

We found that intra-observer agreement of Mason and Morrey classifications were satisfactory (κ = 0.582 and 0.554, respectively), while the AO/ASIF classification had poor intra-observer agreement (κ = 0.483). Inter-observer agreement was higher in the Mason (κ = 0.429-0.560) and Morrey (κ = 0.319-0.487) classifications than in the AO/ASIF classification (κ = 0.250-0.478), which showed poor reliability.

Conclusion

Inter- and intra-observer agreement of the Mason and Morey classifications showed overall satisfactory reliability when compared to the AO/ASIF system. The Mason classification is the most reliable system.

Elbow fractures with carpal injuries

We report four cases with six episodes of concurrent carpal and elbow fractures or dislocations. Few such combinations of injuries have been reported in the literature. We discuss the mechanism and management of such injuries and conclude that elbow injuries should be suspected in severe carpal injuries. Surgical treatment may be required in their management.
