Forearm fractures in children: pitfalls and complications.

Five hundred fourty-seven consecutive forearm fractures in children were studied, with special emphasis on complications encountered. The most important apparent conclusion reached from this study is that greenstick and complete fractures are different, and that some of the pitfalls and complications seen following these injuries can be avoided if different methods of reduction are used for each. Greenstick fractures should be reduced by manipulating them into the correct proper plane of rotation; i.e., maximum pronation for distal third fractures, neutral for middle third fractures, and supination for proximal third fractures. Application of this familiar "rule of thirds" to complete fractures, however, may result in ratational deformity at the fracture site. Completer fractures should be reduced by finger trap traction, allowing the fracture to seek its own level of rotation. Several other observations were also noted. Angulation into radial deviation was found to remodel and equally as well as volar angulation, and remodeling may contine for as long as two years after injury. Growth disturbance following fractures through the distal radial epiphyseal plate is uncommon, but premature closure of the epiphysis did occur in one patient with a typical Type II fracture. Six concomitant nerve injuries were seen; all recovered spontaneously within 3 weeks.
