摘要
采用椎弓根钉与哈灵顿棒加套棒内固定装置,临床治疗胸腰椎不稳定骨折25例,疗效满意。后凸畸形角由术前平均26.88°减少到术后3.72°,移位百分率由术前34.82%纠正到1.0%,被压缩椎体的高度由术前50.92%恢复到92.88%。不全瘫患者术后均有较好的神经功能恢复,完全瘫患者术后恢复较差。该装置具有骨折复位率高,稳定作用强,可防止脱钩或骨界面骨折以及缩短固定节段的优势。
From Jan. 1990 to Jan. 1992, 25 patients suffered from unstable thoracolumbar injuries were treated surgically with a new internal fixative system which composed of Harrington distration rods, inferior hoods, Edwards rob-sleeves and pedicle screws. Kyphosises were corrected from 26. 88° preoperation to 3. 72° postopratively. The translations were reduced from 34. 82% to 1.0%, and the heights of compressed vertebral bodies were restored from 50. 92% to 92. 88%. The recoveries of neurological function were good in incomplete paraplegia patients and were not so good in the complete paraplegia. The fixative system had advantages of improving repositioning of fractures, stabililizing the injured spines, prooventing hook dislocation and shortening fixated ranges.
