摘要
本文分析了应用6种脊柱装置在侧凸矫正中的力学特点,其结果表明:Harrington装置对大于50°的侧凸可提供较大的矫正弯矩,Luque氏装置对侧弯及旋转均有矫正效果。Zielke装置有明显的去旋转作用。若按生物力学原理联合应用两种内固定可获得理想的矫正效果,并能减少脊柱各种併发症。
The mechanical characteristics of scoliosls correction vising six sorts of spinal instrumentation were analysed. The results showed that Harrington instrumentation can provide a large corrective bending moments for a lateral curve more than 50 degrees, Luque's method can pro-ride a corrective force for the curve and rotation, and Zielke instrumentation appears to have a significant action for correcting rotation. If two techniques were used in combination according to the principles of basic mechanics, reliable corrective effect would be obtained and spinal complications might be decreased.
