目的：评估经椎弓根蛋壳技术治疗胸腰椎畸形的临床疗效。方法：2008年12月至2011年12月，应用经椎弓根蛋壳技术治疗不同病因所致的胸腰椎畸形36例，男20例，女16例；年龄20-58岁，平均45岁；其中先天性半椎体畸形5例，陈旧性结核畸形12例，陈旧性创伤伴畸形疼痛14例，强直性脊柱炎后凸畸形5例。对患者的腰痛、Oswestry功能评分和影像学改变进行观察。结果：36例患者的平均手术时间为245min，平均出血量为1900ml。所有患者获得1年以上随访，术后1年所有患者获得融合。术前、术后1周、术后1年患者的腰痛VAS评分分别为7．2±1．4，2．5±1．0，1．8±0．5；ODI指数分别为（72．50±10．80）％，（42．50±11．10）％，（22．50±7．90）％；术后1周及术后1年VAS评分、ODI指数较术前均有明显改善。后凸Cobb角分别为（76．31±2．52）°，（23．66±1．16）°，（23．67±1．16）°；侧凸Cobb角分别为（71．86±4．02）°，（30．81±2．33）°，（30．82±2．32）°。术后1周、术后1年后凸及侧凸Cobb角较术前均有明显变小，术后1年与术后1周比较差异无统计学意义。结论：应用经椎弓根蛋壳技术治疗胸腰椎畸形可取得理想矫形效果及临床疗效。

Objective：To evaluate the clinical effects of transpedicular eggshell technique in treating thoracolumbar de- formity. Methods：From December 2008 to December 2011,36 patients with thoracolumbar deformity were treated with transpedicular eggshell technique. There were 20 males and 16 females with an average age of 45 years old （ranged from 20 to 58 ）. Among them, 5 cases were congenital hemivertebrae deformity, 12 cases were secondary to tuberculotie deformity, 14 cas- es were post-traumatic deformity with pain, 5 cases were ankylosing spondylitis. Low back pain ,living ability, scoliotic Cobb angle were analyzed according to VAS scoring, Oswestry Disability Index （ODI）, radiological examination. Results：Average operative time was 245 min and average bleeding was 1 900 ml in 36 patients. All patients were followed up more than 1 year and obtained bone fusion at 1 year after operation. Preoperative,postoperative at 1 week and 1 year, VAS scoring was 7.2 ± 1.4,2.5±1.0,1.8±0.5,respectively; ODI was （72.50±10.80）%, （42.50±11.10）%, （22.50±7.90）% ,respectively;kyphosis Cobb angle was （76.31±2.52）°, （23.66±1.16）°, （23.67±1.16）° ,respectively;lumbar scoliosis Cobb angle was （71.86± 4.02） °, （30.81 ±2.33）°, （30.82±2.32）°,respectively. Postoperative at 1 week and 1 year, above data had obviously improved than that of preoperative （P〈0.05） ;and there was no significant difference in Cobb angle between postoperative at 1 week and postoperative at 1 year （P〉0.05）. Conclusion ：Treatment of thoracolumbar deformity with transpedicular eggshell technique could obtain effective correcting and clinical results.
