摘　　要：本文介绍一种经椎弓根多钉固定的撑压器，具有坚强的固定力，撑开、压缩和抗旋转能力达到脊柱三维固定的目的。经实验测定，其抗旋转能力比哈氏棒和鲁氏棒联合固定提高３４．４６％．比双根鲁氏棒固定提高３５～４８％。其抗弯能力是哈氏棒和鲁氏棒联合固定的１３０～１４１％，是双根鲁氏棒固定的１３０～１４５％（Ｐ＜０．００１）。The authors designed a new internal fixator for scoliosis---multi-screw fixed distractor-compressor via the vertebral pedicle.The new device has strong forces of fixation,distraction,compression and anti-rotation.It can produce free movememt in three-different levels and fix the vertebral column in three-dimensions.Its anti-rotaion ability is 34-46 per cent higher than that of Harrington-Luque rods,and is 35-48 per cent higher than that of two Luque rods.Its anti-lateral bend ability is 130-141 per cent higher than that of Harrington-Luque rods,and is 130-145 per cent higher than that of two Luque rods(P<0.001).
