In twenty-six cases of Barton's fracture-dislocation of the lower end of the radius, surgical reduction and fixation by a buttress plate was the treatment given, either because closed reduction failed or because the reduction was unstable. The results were excellent or good in twenty, fair in five, and poor in one. Twenty-two patients returned to their previous jobs after an average of four months' disability. This fracture should be differentiated from a Smith fracture on the basis of the obliquity of the fracture line.
