When applying multiple flexible intramedullary nailing technic for treatment of ulna and radius shaft fractures, the authors have improved on the fixation of the end of nails by stapling it into the distal radius and proximal ulna in order to strengthen the rotational instability control. 39 cases of radius or ulna or both bones fractures were treated in a clinical trial and the excellent anatomic reduction was obtained in 37 cases, good in 1 case and medium in 1 case. 22 cases have been followed up longer (3 months -12 months) showed bone healing in time; excellent and good fonctional outcome obtained in 100 percent. 8 cases undergone nail removal without iterative fracture.
