| Abstract: | Objective: This experiment's purpose is to compare the biomechanical stability between the different geometric configuration of three cannulated compression screws fixed the femoral neck fracture and find out the better one to guide the clinical treatment.Methods: The specimen fixed by three 6.5mm cannulated screws was measured on the biomechanical machine. The axial loading,the torsion and the ultimate loading was compared.The experimental data was analyzed by SPSS10.0 statistic software. The statistical significance for the test was set at P<0.05 Results: In the term of anti-loading, the biomechanical strength of the inverse isosceles triangle is the better than the positive isosceles triangle. In the term of anti-torsion, there is not statistically significant difference between the two kind triangle of the biomechanical strength. Conclusion:The result of the experiment support the geometric configuration of the inverse isosceles triangle in treating the femoral neck fracture. |
