Abstract:
[Objective]To study the biomechanics of the femoral neck on the treatment of ischemic of the femoral head in dogs using titanium alloy cage,single core decompression and normal.[Method]Twenty-one couples of fresh moist dogs ' femur specimens were divided randomly into 3 groups.In 2 groups,biomechanical test of the femoral neck was made on one of every couple in different conditions:core decompression,core decompression with titanium alloy cage implanting.The other of every couple was tested as normal control.In the third group,one of every couple was tested in condition of core decompression with titanium alloy cage implanting.The other of every couple was tested in condition of core decompression.[Result]The stiffness and the max load of the single core decompression were less than that of the normal control.The max load of femoral head after titanium alloy cage implanting were lager than that of the core decompression or the normal control.[Conclusion]The titanium alloy cage implanting could increase mechanical support for femoral neck significantly and prevent femoral neck broken after manipulation.
