To investigate the effect of allogeneic bone nail on articular fractures.Ninety-one patients with cancellous bone fracture involved in various joints were fixed with the bone nail or the bone screw. No immunosuppressive agent was used in this series. The average period of follow-up wa s 18 months.All patients except one healed without displacement an d the healing time was within 1-3 months. Joint function was partially limited in 6 patients and others were functioning well.Allogeneic bone nail possesses a good biological compatibility and intensity, thus provides a rigid fixation. Being completely absorbed and ossificated, thus obviating the need for secondary operation, is a suitable internal fixation material for the treatment of articular fractures.
