中文摘要:

  腰椎管成形术是治疗腰椎滑滑脱症的新方法，为此，对腰椎管成形术进行了尸体脊柱生物力学实验研究。结果表明；腰椎管成形术后在前屈、后伸及左右侧弯时的载荷、位移和载荷－应变曲线均优于正常标本。

英文摘要:

  Lurnbar laminoplasty is a new method of treating lumbar spondylolisthesis. Biomechanical studies of cadaver spine were carried out with the new iumbar laminoplasty-The results showed that antetior, posterior and lateral bending load(bending moment)-positi
