Abstract

Monteggia fracture dislocations are uncommon in childhood. Since the term 'Monteggia equivaents' was termed, various equivalents of this entity have been described. However, these fractures with concomitant elbow injuries are exceedingly rare in young children. We present a case of an 18 month-old girl who sustained a fracture of lateral condyle of right distal end of humerus with posterior dislocation of the elbow. We suggest that the fracture pattern can be included under type II Monteggia equivalent on the basis of its characteristics, biomechanics and the mode of injury with supporting literature review for the same.
