目的 分析CT对腰椎骨折脱位患 者行腰椎后路复位、植骨融合、钉棒系 统内固定治疗的应用价值。方法 以我院 2012年3月-2015年3月收治的30例腰1-2椎 骨折脱位患者为研究对象，均行腰椎后 路复位、植骨融合、钉棒系统内固定治 疗，全部患者术前、术后、随访期间均行 CT检查，比较手术前后Cobb’s角、腰椎 JOA评分、脱位率及脱位角。结果 术后6 个月CT显示腰椎融合率100%；术后6个月 cobb’s角、腰椎JOA评分、脱位率、脱 位角分别为(2.6±1.6)°、(24.2±2.5) 分、(0.16±0.04)、(2.7±0.8)°，较术 前的(15.8±3.7)°、(15.2±3.0)分、 (0.37±0.08)、(6.5±1.2)°差异有统计 学意义(P＜0.01)。结论 腰椎后路复位、 植骨融合、钉棒系统内固定治疗腰1-2椎 骨折脱位疗效明确，术前、术后CT检查对 腰椎骨折脱位诊断、治疗方案制定及疗效 评估具有重要价值。

Objective To analyze the application value of CT in patients with lumbar vertebral fracture dislocation treated by lumbar vertebral posterior approach reduction, bone graft fusion and internal fixation of nail-stick system. Methods 30 cases of patients with lumbar 1-2 vertebral fracture dislocation treated in our hospital from March 2012 to March 2015 were treated as the research objects. All the patients underwent lumbar vertebral posterior approach reduction, bone graft fusion and internal fixation of nailstick system. All patients underwent CT examination before and after surgery and during the follow-up period. Cobb's angle, lumbar vertebral JOA scores, dislocation rates and dislocation angles were compared before and after surgery. Results 6 months after the surgery, the lumbar vertebral fusion rate showed by CT was 100%; 6 months after surgery, Cobb's angle, lumbar vertebral JOA score, dislocation rate and dislocation angle were (2.6±1.6)°, (24.2±2.5), (0.16±0.04) and (2.7±0.8)°, respectively while before surgery, they were (15.8±3.7)°, (15.2±3.0), (0.37±0.08) and (6.5±1.2)°, respectively. The differences were statistically significant (P＜0.01). Conclusion The curative effect of lumbar vertebral posterior approach reduction, bone graft fusion and internal fixation of nail-stick system in the treatment of lumbar 1-2 vertebral fracture dislocation is definite. Preoperative and postoperative CT examination is of important value in the diagnosis of lumbar vertebral fracture dislocation and formulation of treatment plan.
