In this study the authors find that in the fractures of the forearm in the adults, osteosynthesis with tubular plates and compression, where is possible, is to prefer as the intramedullary nailing. Plates give a better reduction and immobilization of the fractures and allow a quickly healing, but they request a finest surgical technique than the intramedullary nailing. Our review is of 44 bifocal fractures of the forearm in adult over 127 cases that we have treated in the Orthopaedic Department of the University of Florence. Our follow-up ranged between 12 and 1 year. Eleven have been operated with Kirschner pins and 2 with Rush nailing with excellent results in 54%, and 31 with AO plates with good and excellent results in 80%.
