Monteggia and equivalent lesions. A study of 41 cases.

Forty-one patients who suffered from a Monteggia fracture and were treated between 1984 and 1993 were reviewed retrospectively using a new motion score of the elbow joint. There were 14 children and 27 adults of whom 34 were available for review. The results in children were significantly better than those of the adults. Among the adults, the final results of the patients who had a Bado Type 1 equivalent injury were significantly worse than those of the other groups, especially when associated with a fracture of the radial head. The type of fracture, open or closed, the presence of a fracture of the olecranon, and the energy level of the trauma did not have any significant prognostic value. Good correlation was shown between the new motion score and the Figgie elbow score. The Bado Type 1 equivalent injuries should be considered as a special subgroup of the Monteggia lesion, necessitating extra attention in treatment and rehabilitation, and a close followup of the patient.
