Description

Bado reviewed Monteggia original fracture description further defining an injury into 4 types. Bado classification defines a group of traumatic ‘double bone‘ injuries having in common a ‘Monteggia lesion‘ (ulna fracture) with a dislocation of the radio-humero-ulna joint (radial head dislocation either anterior, lateral or posterior)

History

1814Giovanni Battista Monteggia (1762–1815) recorded two observations of a ‘traumatic lesion distinguished by a fracture of the proximal third of the ulna and an anterior dislocation of the proximal epiphysis of the radius‘ [Monteggia GB, 1814 p131-133]

1855Joseph François Malgaigne (1806-1865) stated ‘any fracture of the ulna, without exception, can be found with a radial dislocation

1967 – Bado further classified traumatic forearm fracture of the ulna with disruption of the radio-humero-ulna joint:

  • Type 1: Anterior radial head dislocation. Fracture ulna diaphysis with anterior angulation. 60% of cases.
  • Type 2: Posterior/posterolateral radial head dislocation. Fracture ulna diaphysis with posterior angulation. 15% of cases.
  • Type 3: Lateral/anterolateral radial head dislocation. Fracture ulna metapysis. 20% of cases.
  • Type 4: Anterior radial head dislocation. Fracture proximal 1/3 radius AND ulna. 5% of cases.
