AF系统内固定治疗胸腰段脊柱骨折

目的：评估ＡＦ的内固定对胸腰段脊柱骨折的疗效及其应用价值。方法：对４０例主前按Ｆｒａｎｋｅｌ分级说不定损伤程度。怀根内固定的进钉点。行ＡＦ内固定。术后以上述分级方法再次对４０例患者进行评平，并作Ｘ线、ＣＴ检查对ＡＦ疗效进行分析，术后平均随访１５个月。结果：术前Ｆｒａｎｋｅｌ分极Ｂ～Ｄ级者均获１～２级的进步。全部病例无医源性神经根受损或断钉。Ｘ线随访示３６例患者椎体序列恢复正常。有３例术后６个月后发

Surgical Treatment of Thoracolumbar Vertebrae Fracture by Atlas Fixation System

To evaluate the effectiveness and application value of the Atlas Fixation (AF)for thoracolumbar fracture. Methods:Forty patients with fracture of thoracolumbar spine were operated by AF internal fixation. Before operation, the patients were evaluated by the Frankel's calssification;after operation all patients were evaluated again,including X-ray and CT scans. Results:The patients of Frankel's B～D were improved by 1～ 2 scroe after operation. There were no iatrogenic nerve root injury and broken screws. Thirty-six patients had regained the normal spinal sequence. Of 40 cases, 3 had peri-screws abscess and 4 lost the anterior height of spine body. CT scans following-up indicated that the spinal canal volumes were all returned to above eighty percent of normal. Conclusion:Compared with other spinal posterior internal fixation, Atlas Fixation has better results in effectiveness and simplification.
