摘要
目的 总结DRFS在胸腰椎骨折脱位中的治疗体会。方法 对 6 7例行DRFS内固定的胸腰椎骨折脱位病例术前、术后的X线片变化及其功能恢复情况进行观察和分析。结果 6 7例获得 9~ 38个月的随访 ,术后伤椎的高度及脊柱Cobb角均有较满意的恢复 ,神经功能按Frankel分级有 1~ 3级的改善 ,断钉 1例 ,松动 6例 ,已有 11例取出内固定物 ,优良率为 89 5 5 %。结论 DRFS后路短节段经椎弓根内固定治疗胸腰椎骨折脱位 ,操作简单 ,易于安置 ,并能最大限度地恢复椎体及椎间隙的高度 。
Objective To summarize the treated experience with DRFS for the fracture and dislocation of thorace-lumbar spine.Methods There were 67 cases of thorace-lumbar fractures fixed with DRFS,and their X-ray material and nervous function were analysed. Results Sixty-seven cases had been followed-up from 9-38 months,the height of the injured spinal body and the spinal Cobb angle had satisfactorily restored after operation,nervous function had improved by one grading or more according to Frankels grading.Pedicle screw breaking occurred in 1 case,loosening 6 cases.The excellent and good rate was 89 55%.Conclusion DRFS short posterior internal fixation for thoraco-lumbar fractures,could improve enough on the height of the spinal body.The advantages of this system are simple to operate and easy to adjust.It provides a strong and stable basic for the reconstruct and restores function of the spine.
