池氏经椎弓多钉固定撑压装置矫正脊柱侧凸

Scoliosis treated with Chi's rod and multi-serews fixation distraction-compression system via vertibral pedile

应用池氏经椎弓多钉固定撑压装置矫治脊柱侧凸患者150例，Cobb角大于100°的侧凸矫正率为59．2％，50°～100°为68．63％，50°以下为76．71％。术中并发推弓定位不准2．4％，螺钉过长0．54％，胸膜和脊膜刺破0．27％，神经根损伤0．13％。术后并发断律为3．3％，断钉为0．41％，折弯为0．82％，脱出为0．41％，创口感染为2％，畸形复发率4％，假关节为3．3％。

150 cases of scoliosis were treated with Chi's rod and multi-screws fixation distraction-compression system via vertebral pedicle. The result showed that if the Cobb' s angle was over 100°, the mean correction rate was 59. 2%, if the Cobb's angle was within 50~100° the mean correction rate was 68. 63% and if the Cobb's angle was below 50°, the mean correction rate was 76.71%, The faults within the operation included imprecise drilling point (2. 4%), breaking of meninges and pleura (0. 27%), injury of nerve root (0. 13%). The mean complication rates after the operation were 3.3%of broking rod, O.41% of broking screws, 0. 82% of bending screws, 0. 41 % of lossening of screws,2% of infection of the incision,4% recurrence of the malformation and 3. 3% of pseudoarthrosis.
