New Bado Type IV Monteggia fracture dislocation variant occurring in a child: a case report

Abstract

Bado Type 4 Monteggia fractures are defined as fractures of the proximal or middle third of the ulna occurring together with a fracture of the proximal radius with anterior radial dislocation. These lesions are rare comprising approximately 1% of Monteggia fracture subtypes. We report a previously non-classified further subtype of the Bado Type 4 Monteggia fracture namely, a fracture of the proximal ulna occurring together with a Salter-Harris Type II fracture dislocation of the radial head with anterior radial dislocation occurring in a child. The acute presentation enabled the radial head to be reduced and both the radial and ulnar fractures were held with Kirschner wires. At 6 weeks post-operatively the Kirschner wires were removed and the patient demonstrated a normal range of motion.
