目的通过分析70例腰椎峡部裂伴随征象,提高飞行员腰椎峡部裂的检出率,减少漏诊,为招飞和飞行员健康鉴定、改装体检提供依据。方法对2012年5月-2014年8月在某中心行年度大体检飞行员进行腰椎正、侧、斜位平片检查,明确诊断为腰5椎弓峡部裂的飞行员70名,分别在正侧位片上计数腰椎侧弯例数、腰5趋于骶化例数、腰骶角增大例数、承重线前移例数、腰椎序列不连续例数、腰5下关节突结构紊乱例数、腰5椎体反楔变例数、腰5/骶1椎间隙变窄例数和腰5椎体下终板许莫氏结节例数,分析其与腰椎峡部裂形成的关系。结果腰椎峡部裂9种伴随X线征象中,腰5附件下关节突结构紊乱出现率最高,占75.7%;腰5趋于骶化出现率次之,占72.9%;承重线前移出现率再次之,占64.3%。结论在招飞和飞行员健康鉴定、改装体检腰椎摄片工作中,应注意观察伴随征象,有针对性加照腰椎双斜位片或CT扫描检查,从而减少腰椎峡部裂的漏诊率。
Objective To improve the detection rate of lumbar isthmus and reduce the missed diagnosis of 70 cases of lumbar spondylolysis for the purpose of providing the basis for the health assessment of pilots and pilot pilots and physical examination. Methods From May 2012 to August 2014, 70 pilot pilots who were diagnosed as lumbar spondylolysis were examined by positive, lateral and oblique plain radiographs of the major pilots at a certain center in the year of May 2012, On-chip count of lumbar scoliosis cases, lumbar 5 tends to the number of sacralization, lumbosacral angle increased the number of cases, load-bearing line of the number of cases, lumbar sequence of discontinuous cases, lumbar 5 under the ganglion structure disorder cases, lumbar 5 vertebral body anti-wedge change number, lumbar 5 / sacral 1 intervertebral space narrowing number and lumbar vertebral end plate Xu Morse nodules number, analyze the relationship with lumbar spondylolysis. Results Among the nine kinds of X-ray signs of lumbar spondylolysis, the incidence of inferior ganglion dislocation in lumbar spine 5 appendix was the highest (75.7%), followed by sacralization of lumbar spondylosis (72.9%), It accounted for 64.3%. Conclusions During the operation of recruit and pilots, the lumbar spine imaging should be observed with the accompanying signs, with double-sided lumbar spine or CT scans, so as to reduce the rate of misdiagnosis of lumbar spondylolysis.
