Radial head fractures are the commonest fractures in the elbow. They are often associated with other injuries: ligamentous, cartilaginous or other fractures. Associated injuries are important determinant of the management of the radial head fracture. These should be carefully looked for, diagnosed and treated. The original Mason classification for this fracture has been modified to include the associated injuries and their treatment. CT scan is a helpful diagnostic tool and should be used if available. Radial head fractures can be treated either conservatively or operatively (by excision, open reduction and internal fixation or prosthetic replacement). Undisplaced or minimally displaced fractures should be treated non-operatively. Internal fixation by headless cannulated screws is the preferred treatment for displaced fractures. It provides satisfactory biomechanical stability, can be done through a smaller incision, has less complications and lesser requirement of later removal of screws. Small number of fractures with comminution of neck would require plate fixation. Unfixable fractures in elderly can be treated by excision while such fractures in younger population or associated with significant soft tissue or bony injuries would require prosthetic replacement.
