目的：探讨胸腰椎骨折后经伤椎植骨置钉对矫正度丢失的干预作用。方法回顾性分析2011年6月至2013年12月经我院治疗的胸腰椎骨折患者86例，其中经伤椎椎弓根植骨固定组（A 组）37例，跨伤椎椎弓根钉固定组（B 组）49例，所有病例按自制伤椎形态量表分为轻、中、重度。测量两组患者术前、术后3 d 及取出内固定3 d 后的矢状位 Cobb 角、伤椎压缩率及椎间隙高度，计算矫正度丢失率，并将相同程度的两组患者进行比较。结果所有患者随访13~20个月，平均16.5个月，评分轻度的患者两种手术方式后伤椎矫正度丢失无明显差别，评分为中度及重度的患者，B 组矫正度丢失明显小于 A 组。结论自制伤椎形态量表与术后矫正度丢失存在相关性，中、重度患者应对伤椎进行干预以减少矫正度丢失。

Objective To assess the efficacy of the intervention in treatment of thoracolumbar fractures with bone graft and vertebral pedicle screw in fractured vertebra. Methods We retrospectively analyzed 86 patients suffered from thoracolum-bar fractures in author's hospital from June 2011 to December 2013. 37 patients(group A)were treated with bone grafting and vertebral pedicle screw in fractured vertebra,49 patients(group B)were treatment across injured vertebral. All the patients were seperated to mild level,moderate level and severe level. Before and after surgery and at follow-up,cobb angle,vertebral com-pression rate and intervertebral space height were evaluated. Two groups of patients with same level were compared. Results All the patients were followed-up from 13 to 20 months with an average of 16. 5 months. The follow-up showed the lose of verte-bral correction degree was not significantly different in mild level patients,but group B was significantly lower than that of group A in moderate level and severe level patients. Conclusion The relationship between the loss of kyphosis correction de-gree and injured vinjured vertebra morphology scale is obviously,and intervention is essential in moderate level and severe lev-el patients to reduce the lose of vertebral correction degree.
