INTRODUCTION: @entity2850 ( @entity2850 ) system was designed to provide bone stability and to enhance bone healing. However, implant failure, nonunion and instability are still frequently encountered complications. The purpose of this study was to assess and compare the biomechanical characteristics of a novel @entity2166 ( @entity2166 ) with the commonly used @entity2850 . MATERIALS AND METHODS: Twelve 4th generation composite artificial femoral bones were used. Transverse @entity174 was created in all bones, 6 femurs were fixated using the novel @entity2166 , whereas the other 6 femurs were fixated using the traditional @entity2850 . All samples had undergone a non-destructive repetitive different forces (axial compression, bending and torsion), to evaluate the biomechanical differences between the two plating systems. RESULTS: Under axial load the mean stiffness value was 439.0  N/mm for the @entity2166 and 158.9  N/mm for the @entity2850 , @entity2166 showed a statistically significant stiffness value than @entity2850 with a P value of 0.004. There was no significant difference in flexion/extension bending strain values between @entity2166 and @entity2850 . However @entity2850 provided significantly stiffer fixation in medial and lateral bending tests than @entity2166 (P  =  0.037) and (P  =  0.016) respectively. But no significant difference was detected between the two plating system in the applied torsional stress. CONCLUSION: These results do not show any significant biomechanical difference in the applied torsional and bending stresses between @entity2850 and @entity2166 . However the remarkably increased persistent compression effect of the @entity2166 created a considerable stress on @entity174 edges which may accelerate bone healing.
