此摘要是机器生成的。

预先调节椎间盘 (IVD) 样本可能不需要进行机械测试. 缓慢的预调速率 (0.01毫米/秒) 降低了刚度,建议避免这些速率以保持组织特性.

科学领域:

  • 生物机械工程 生物机械工程
  • 组织力学是组织力学.
  • 脊柱研究研究 脊柱研究

背景情况:

  • 膜间矩阵 (ILM) 抵御椎间盘 (IVD) 中的分层.
  • 了解ILM的机械特性对于评估磁盘损伤风险至关重要.
  • 由于ILM的粘弹性,可能需要在机械测试前进行预先调节.

研究的目的:

  • 为ILM优化机械测试协议.
  • 调查预条件对ILM刚性和强度的影响.
  • 为了确定在ILM的粘合皮试验之前是否需要预先调节.

主要方法:

  • 测试了88个猪椎盘环状样本.
  • 样品被随机分为四组:没有预先条件,或预先条件为0.01,0.1或1毫米/秒的应变速率.
  • 预先调试涉及15%应变的10个循环,随后进行180°粘合剂剥皮试验.

主要成果:

  • 与未经预先条件的样本相比,在0.01毫米/秒的预先条件的样本显示出明显降低的刚度 (p=0.014).
  • 两组之间没有观察到其他统计学上显著的硬度或强度差异.
  • 该研究发现,在测试速率下预条件对ILM机械性质没有显著影响.

结论:

  • 对于ILM的180°粘合皮试验,可能不需要预先调节.
  • 如果使用预先调节,应避免缓慢的速度 (0.01 mm/s),因为可能对组织特性产生负面影响.
  • 可能需要进一步的研究,以充分阐明预条件在IVD机械测试中的作用.
