These fractures are usually posteriorly angulated (apex anterior) and can generally be reduced closed, ideally under general anesthesia. Impediments to reduction are interposed periosteum and pronator quadratus.
Fractures with an intact dorsal periosteum are stable after reduction and may not require wire fixation. K-wire stabilization may be strongly indicated in some cases.
Anteriorly angulated (apex posterior) fractures are less common and are also generally reduced closed. Impediments to reduction are the extensor tendons.
