Presentation
Elbow pain after suffering a fall on an outstretched hand.
Patient Data



There is a partial articular fracture with a depressed fragment involving the radial head (Mason type II). The anterior and posterior fat pads are not well visualized on the lateral projection but joint effusion/hemarthrosis is almost certainly present.
The osseous alignment is well maintained throughout.
The bone density is decreased, most likely senescent in etiology.
Case Discussion
Radial head fractures are the most common fracture in the elbow in the adult population and are often due to direct longitudinal loading, a fall on an outstretched hand. Radial head fractures can be graded using the Mason classification system.
