Malunited fractures of the forearm in children

Malunion of fractures of the forearm in children can lead to permanent disability. The capacity of the radius and ulna to remodel spontaneously after malunion has been assessed in this study. Forty-nine children who had malunited fractures of the forearm were examined when the remodelling process was complete. It was noted that fractures of the distal third of the radius and ulna led to fewer problems than those of the diaphysis. It was concluded that malunion of the distal third of the radius and the ulna will remodel satisfactorily providing the child is less than 14 years of age. Gross malunion of the midshaft of the radius and ulna will spontaneously correct in an infant but little useful correction of deformity can be anticipated in diaphysial fractures when the child is aged eight years or more.
