[Experimental research of viscoelasticity of C2-T1 cervical vertebra].
This is a research on the characteristics of stress relaxation and creep of cervical vertebra (c2-t1) of fresh body (18 cases). The effect of stress relaxation and creep of cervical vertebra was detected by simulating front and back routes operation. Reduced curve and data in the constant strain and stress were obtained. By using regression analysis method the reduced relaxation and creep functions were acquired. The experimental result showed the decrease of viscoelasticity in simulating operation conditions.
