Complex Monteggia Fractures: Anatomic Reduction Optimizes Outcome
Monteggia fractures involve a proximal ulna fracture associated with a radiocapitellar joint dislocation. The Jupiter subtype classification of Bado type II fractures further characterizes the severity of proximal ulna comminution and coronoid fragment involvement. The complexity of the injury also is considerably increased based on the degree of radial head fragmentation. Reduction maneuvers and appropriate plate selection are critical to achieving anatomic reduction, which may substantially affect outcomes.
