A rare Wilkins group II fracture of the proximal radial metaphysis.

Abstract

In this study, we report a rare fracture of the proximal radial metaphysis in an 11-year-old child, involving an anterior displacement of the proximal radial metaphysis instead of a displacement of the epiphysis, which preserved its normal connections with the capitellum. This fracture was successfully treated by closed reduction and wire fixation. The reduction maneuver attempted to reduce the proximal radial metaphysis under the epiphysis instead of doing the opposite. The mechanism of this injury is probably an extension strain on a forearm in pronation associated with a violent contraction of the biceps brachialis muscle. This fracture is considered as a rare example of Wilkins group II angular fracture of the proximal radial metaphysis, without proximal ulnar fracture.
