Abstract:
[Objective]To discuss the difference of mechanical stability in using different fixation methods in treating radius and ulna fracture,in order to provide a theoretical basis for clinical applications.[Method]In the experiment,15 pieces of fresh radius and ulna were used to produce middle-part transverse fracture models(A3.2)which were fixed by three different methods(double plate fixation group,double-intramedullary nail fixation group,ulnar intramedullary nailing + radial plate group).Through biomechanical tests,axial stiffness,bending stiffness,torsional stiffness and the equivalent stiffness were compared.[Result]There were no difference between double-plate group and ulnar intramedullary nailing + radial plate group,the stability in these two groups were higher than that in double-intramedullary nail fixation group.[Conclusion]Ulnar intramedullary nailing + radial plate has a good biomechanical property,it can provide firm fixation and with less trauma.So it is a good fixation.
