Methods The models of fracture of femoral condyle were made on 16 fresh cadaver femurs (C1 of AO classification) and fixed by supracondylar intramedullary interlocking nail, dynamic condyle screw plate, L shaped condyle plate and Ender's nail fixation respectively. To compare the four different methods by experimental stress analysis and theoretical analysis of finite element method. Results Under the same load condition, the supracondylar intramedullary interlocking nail absorbed more energy during axial loading compared with the other constructs(P<0.01). The dynamic condyle screw plate had the greatest torsional stiffness (P<0.01). There were no significant differences in torsional stiffness between GSHN and DCS. Conclusion Using supracondylar intramdullary interlocking nail and the dynamic condyle screw plate are better than the other internal fixation methods and deserve to be put into clinical application and populatization.

Objective: Tibial fractures fixed by intramedullary expand Self locking Nail(IESN) were tested for the sake of understanding their biomechanical function,so as to provide the theoretical basis for clinical practice. Methods: The rigidity of lower tibial fractures fixed by the IESNs was compared with that of fractures fixed by intramedullary interlocking nails in the anti-torsional rigidity, the anti-bending rigidity, the anti-axial tensile test and the fatigue test. In the experiment, 12 pieces of flesh tibias were used. Results: The fatigue and bending rigidity of IESN were better than those of intramedullary interlocking. The torsional rigidity and axial tensile rigidity of intramedullary interlocking nail were little superior to IESN (P<0.05). Stress shelter of IESN was less than that of intramedullary interlocking nail. Conclusions: The IESN had fine biomechanical characteristics in fixation for lower tibial fractures and can produce firm fixation for lower tibial fractures, thus being of value in the clinical practice.
