Barton's fracture

Overview
A Barton's fracture is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint.

There exist two types of Barton's fracture - dorsal and palmar, the latter being more common. The Barton's fracture is caused by a fall on an extended and pronated wrist increasing carpal compression force on the dorsal rim. Carpal displacement distinguishes this fracture from a Smith's or a Colles' fracture. Treatment of this fracture is usually done by open reduction and internal fixation with a plate and screws, but occasionally the fracture can be treated conservatively.

Eponym
It is named after John Rea Barton (1794-1871), an Irish surgeon who first described this in 1814.
