The Radial Head Fractures
Radial head fractures represent the most common fracture of the elbow in the adult population, accounting for 1.7%–5.4% of all adult fractures. Approximately 85% of these fractures occur in young, active individuals ranging in age from 20 to 60 years-old. Radial head fractures may occur in isolation or may be part of a more extensive traumatic elbow injury. An estimated 20% of all acute elbow injuries have an associated radial head fracture (Fig. 1). In elbow dislocations, a radial head fracture is commonly associated with other traumatic pathologies including medial collateral ligament (MCL) rupture, olecranon fracture, and/or coronoid fracture. Therefore, in the setting of trauma, the elbow must be carefully evaluated to rule out associated ligamentous and bony pathology.
