ABSTRACT
We have studied the characteristics of stress relaxation and creep on lumbar vertebrae(T12-T5) of 18 fresh corpses. We measured the stress relaxation and creep of the normal group(intact spine), the control group 1(simulating the operations by the front route) and the control group 2(simulating the operations by the back route). Then we obtained the stress, strain-time curves and data under the conditions of constant stress and strain. By using regression analysis we obtained the reduced stress relaxation and creep functions. Finally, We analyzed and discussed the effects of the operations of excising the disc intervertebrales by the front route and the back route.
