对１２个新鲜脊柱标本的纵向加载实验，研究了节段脊柱材料在离体状态下的压缩力学特征，测得颈、胸、腰段脊柱的弹性变形范围，为设计人工椎体的弹性提供了参考数据。
The longitudinal loading experiments on 12 fresh spine specimens were carried out to study the compressive mechanical characteristics of segmental spinal materials in vitro. The range of elastic deformation of cervical, thoracic and lumbar vertebrae was determined, which provided the flexibility for designing artificial vertebral body Reference data
