摘要
对32例各种类型的脊柱后凸和后侧凸患者行全脊椎截骨加器械矫正术，截骨后使脊髓缩短2～5cm，平均2．8cm。临床结果表明，脊髓缩短在4cm以内者脊髓功能正常，双下肢无神经症状出现，而超过4cm者，由于脊髓迂曲变宽太多，骨性椎管容纳不了就会挤压脊髓产生双下肢神经症状。2例脊髓牵长1cm者双下肢立即出现神经症状。说明脊髓对缩短有很大程度的耐受力，而对牵长则极不耐受。
32 cases oI different types of spinal kyphosis and kyphoscoliosis were treated with completespinal osteotomy and with intrurnents. The spinal cord were shortened by 2cm to 5cm after osteotomywith an average shortening of 2. 8cm. The clinical operation indicated that when spinal cord shortenednot more than 4cm,the function of spinal cord would be normal and the limbs were of no neurologicalcomplications. But,if the spinal cord shortened more than 4cm,spinal cord were too tortuous and broad-ened,and the spinal canal could not he1d spinal cord and compress spinal cord causing neurological corn-plications of limbs. Spihal cord of 2 cases were extented by 1cm causing neurological complications oflimbs irnmediately. The clinical study shows the shortened spinal cord is very tolerable, but extentedspinal cord is not tolerable.
