Monteggia fracture dislocations can be classic or equivalents. Equivalents, also known as Monteggia like lesions, are very rare especially type III and IV, which have been added to the literature after Luis Bado presented the original classification system of Monteggia fracture dislocations. Type III equivalent is classically defined as a proximal ulna fracture associated with a fracture of the lateral condyle of the humerus. In the literature only seven such cases have been reported so far. Here we present two such cases where one eight-year-old boy had a complex type of injury with a shear type fracture of the lateral humeral condyle and other a seven-year-old boy who had a plastic deformity of the ulna with an avulsion type fracture of the lateral humeral condyle. We also try to describe a novel mechanism of injury, known as, “Barzulla circle”, for the classical as well as equivalent type III Monteggia fracture dislocations.
