后路内固定侧前方减压治疗胸腰椎骨折并脊髓损伤

报告５０例胸腰椎骨折后路Ⅰ期内固定及侧前方减压。４２例平均随访２年８个月。伤椎椎体前缘高度由４８％恢复到９２．４％，Ｃｏｂｂ角由平均１７．４°恢复到２°。椎弓根距由增宽１１．５％下降到增宽１．２％。ＣＴ示椎管矢状径明显扩大。结果显示：采用棒套筒器械复位满意，经后路行侧前方减压彻底。其优点是创伤小，手术操作简便，复位好。

Posterior fixation and posterolateral decompression for new thoracolumbar fractures in fifty cases

cases were treated with rod-sleeve reduction technique for posterior fixation and posterolateral decompression of fresh thoracolumbar fractures. The average follow-up period was 2 years and 8months. The fractured vertebral height along the anterior part restored from 48% to 92. 4%. The kyphosis of the fractured vertebra reduced from 17. 4 degrees to 2 degrees. The distance betwan the two radix arcus of the fractured vertebra reduced from 11. 5% to 1. 2%. CT scans after the operations showed the sagittal diameter of the fractured vertebra increased a lot. The results showed that the rodsleeve reduction technique could restord thoracolumbar fractures satisfactorily and meanuhile posterolateral decompression technique allowed direct decompression of the thecal sac thoronghly. This system is effective, relatively simple, and less tramatic.Author's address (Department of Orthopaedic, Xin Qiao Hospital, The Third Military Medical College,Chongqing, Sichuan, 630037)
