Monteggia fractures.

Monteggia described a fracture of the proximal third of the ulna with anterior dislocation of the radial head from both the proximal radioulnar and radiocapitellar joints. Application of this eponym to all injuries with radiocapitellar subluxation or dislocation has led to some confusion. In addition, there are substantial differences between Monteggia injuries in children and adults. With careful definition, specific subsets of patients may benefit from consideration as a separate type of Monteggia injury.
