The mechanical behavior of fourteen fresh human lumbar motion segments taken at autopsy from males with an average age of 29 yr was studied. Forces up to 1029 N were applied in anterior, posterior and lateral shear; and moments up to 95 Nm were applied in flexion, extension, lateral bending and torsion. In response to these loads endplate displacements up to 9 mm and rotations up to 18 degrees were measured. Stiffness values ranged from 53 to 140 N mm-1 in response to the shear forces and 6-11 Nm degree-1 in response to the moments. Lumbar motion segments can develop significant passive resistances to loads in situations where they are allowed to undergo substantial deformations.
对14个从平均年龄29岁男性尸体上获取的新鲜人体腰椎运动节段的力学行为进行了研究。在前、后和侧方剪切中施加高达1029 N的力；在屈曲、伸展、侧方弯曲和扭转中施加高达95 Nm的力矩。响应这些载荷，测量到终板位移高达9 mm，旋转高达18度。响应剪切力时的刚度值范围为53至140 N/mm，响应力矩时为6至11 Nm/度。在允许腰椎运动节段发生大量变形的情况下，它们能够对载荷产生显著的被动阻力。
