Objective To inspect the loading strength of a newly designed femur prosthesis with cage on the tension side for improving its design and clinical application. Methods A straight cementless femur prosthesis of total hip joint with cage on the proximal tension side was designed according to the geometry parameter of proximal femur of Chinese people. The concepts of proximal press-fit fixation, hypo-distal fixation, interface osteointegration and bone fusion with the cage were adopted in the prosthesis. Ti-6Al-4V forging workblanks were used in manufacturing with CAD/CAM technology. One prosthesis was taken randomly from finished products of each No.0, 1, 2, 4 group(with different) matched by (+0, +2) head with 26 mm diameter. The weight-loading test was done at 1 body weigth (BW), 3-8 BW respectively on INSTRON 4507 200kN univeral experiment machine universal material study machine with the prosthesis in a extraversion position of 18?. Results No plastic deformation and crack appeared when any of the prosthesis bear 1, 3-8 BW loading. The ultimate loading limit of No.1 and No.4 prosthesis was 57.6 kN and 81.8 kN respectively. Destroy first appeared at the stress collection area of the neck when the size of neck was relatively small. When the size of neck was big enough, break occurred at the stress collection area of the cage on the tension side. Conclusion The intensity strength of weight-loading of the femur prosthesis can not be destroyed even with a cage on the proximal tension side. It can endure the weight loading of hip in daily activities, and even strengthen due to the bony growing in proximal femur.
