摘　　要：目的 :研究腰椎不同部位对稳定性所起作用及3种不同术式对腰椎稳定性的影响。方法 :选5具成尸脊柱(L 1-S 1) ,模拟3种不同术式 ,在5个部位 ,以6种状态 ,进行测试。结果 :椎间盘是一个椎节的主要负重结构 ,全椎板切除术对腰椎稳定性影响最为显著。结论 :全椎板切除术极大破坏腰椎稳定性。Objective:The experiment is designed to evaluate the effect of different structure of lumbar spine and of three diffenet surgical methods on stability of lumbar spine.Methods:Three different surgical methods are simulated in five lumber specimens of adult cadavers (L1-S 1).Every specimen is tested in five parts of lumbar spine by six methods.Results:Intervertebal disc is the main structure of load on a segment.Total leminectomy have great influence on stability of lumbar spine.Conclusion:Total laminectomy destroyed the stability of lumbar spine.
