Radial head fractures are a common elbow injury. Imaging techniques such as magnetic resonance imaging have a role to play in identifying injuries that cannot be seen on plain radiographs. Using this imaging method, more than three-quarters of patients in this study were observed to have an associated injury, with the lateral collateral ligament most frequently injured.


Radial head fractures account for approximately one-third of all elbow fractures. Standard radiography may not pick up associated injuries such as chondral defects or ligamentous sprains and tears. The purpose of this study was to identify such injuries using additional magnetic resonance imaging (MRI) in patients presenting with a radial head fracture.
