Interobserver and intraobserver variations in radial head fracture classification-assessment of two classification systems.

ABSTRACT:

Objective

The aim of this study was to evaluate the intra- and interobserver variation of two classification systems for radial head fractures (Mason and Charalambous classifications) using plain radiographs.

Material and methods

Five observers classified 30 radial head fractures as per the two classifications using anteroposterior and lateral elbow radiographs. Assessments were done on two occasions, at least 6 weeks apart.

Results

The interobserver and intraobserver variation of the Mason classification showed fair (mean kappa = 0.33) and moderate agreement (mean kappa = 0.43) respectively. The interobserver and intraobserver variation of the Charalambous classification showed moderate agreement for both (mean kappa = 0.42 and 0.49 respectively). A greater proportio
