| Abstract: | Relaxation, creeping and unidirectional tensile tests werc made inliving rabbit cervical vertebra C3-C5.Relevant biomechanical tests werealso made in rabbit after C4 lamina resection with and without MMA/Sand MMA repair. Based on in-vivo tests using 3-components model,relaxation and creeping modules Y(t),J ( t ) ] were calculated and diff-erential and integral constitutional equations obtained. The results sho-wed that after lamina resection, the stability of cerVical vertebra of ra-bbit was disturbed and the stability recovered after lamina repair, thussuggesing the necessity and feasibility of lamina repair. |
