椎弓根内固定手术系统治疗胸腰段骨折脱位的临床分析

目的评价后路AF椎弓根内固定系统治疗胸腰段爆裂型骨折脱位的临床意义。方法回顾分析采用AF后路椎弓根内固定系统复位、固定＋椎板切除减压＋取髂骨植骨融合的手术方法治疗72例胸腰段爆裂型骨折脱位伴不同程度神经损伤患者的临床疗效。结果所有患者平均随访4年8个月,无特殊并发症。椎体前缘平均高度由术前的60%提高到术后的95%,Cobb’S角由术前平均20°改善至术后平均3°,神经功能均有Ⅰ级以上恢复。结论AF椎弓根内固定手术系统治疗胸腰段骨折脱位,具有良好的复位、减压、三维矫形和短节段牢固内固定等特点,是一种理想而有效的临床手术方法。

Clinical analysis on the treatment of thoracolumbar fracture and dislocation by pedical screw spinal system

Objective To evaluate the clinical effects on the treatment of thoracolumbar bursting fracture and dislocation by AF pedical screw spinal system.Methods The clinical treatment result of 72 cases of thoracolumbar bursting fracture and dislocation with the nerved injury treated by AF pedical screw spinal system were reviewed and analyzed.Results All 72 cases were followed up an average period of 4 years and 8 months.There were no special complication.The average height of anterior border of vertebral body raised from preoperative average height of 60% to postoperative average height of 95%.The cobb＇s angle improved from preoperative average of 20° to postoperative average of 3°.The neuro function recovered more thanⅠgrade.Conclusion AF pedical screw spinal system treating the thoracolumbar bursting fracture and dislocation is a kind of effective and ideal clinical method.It have characteristics of good reduction,good decompression,orthopaedic in three-dimensional space and short segmental transpedicular fixation.
