中文摘要:
  采用生物力学方法研究各种减压术对胸腰段脊柱稳定性的影响。结果表明:椎板减压术组抗弯强度降低最明显,约为对照组的1/3,屈伸活动则增加1倍;侧前方减压术使屈曲状态下水平位移及旋转角均增加,而抗压及抗弯强度降低;侧方减压术使水平位移及旋转角明显增加并使抗压强度降低最明显。实验结果提示各种减压木有引起胸腰段脊柱失稳的趋势,临床应认真选择减压水井采用适当措施重建胸腰段脊柱稳定。
英文摘要:
  The effects of three types of decompression on the stabilization of thoracolumbar spines were studied by biomechanics. The results were; (1)The range of flexion-extension were gradually increased in both lateral and posterior decompression groups. (2)The
