[Complex injuries of the upper end of the 2 forearm bones].
Thirty-four cases of severe trauma to the proximal ends of both bones of the forearm have been seen. All were treated surgically. A classification is proposed related to the site of the ulnar fracture. Type I is metaphyseal and the displacement is posterior, the reverse of that of a Monteggia fracture, with a posterior dislocation of the superior radio-ulnar joint. Type II is epiphyseal with anterior displacement. The superior radio-ulnar joint is intact. Type III is metaphysio-epiphyseal with anterior displacement. Type IV is the same with posterior displacement. Fractures of the radial head are present in all cases with posterior displacement and in these types, secondary displacements and non-unions are frequent (six cases). These were related to inadequate fixation of the ulna and to resection of the radial head which led to an increased strain on the ulnar fracture. Severe limitation of movements was infrequent (five cases) and was usually seen in fractures with posterior displacement. It was related to the time of cast immobilization and to the fracture of the radial head. Fractures with anterior displacement and an associated fracture of the radial head were rare but had a better prognosis in spite of the intra-articular site of the fracture. The relevance of repair of the radial column is stressed as being as important as stable fixation of the ulnar fracture.
