战斗机飞行员颈椎退变研究

目的 了解战斗机飞行人员颈椎退变情况。方法对5年前作过MRI检查的战斗机飞行员（甲组，平均年龄47岁，平均累计飞行时间2100h，乙组，平均年龄27岁，平均累计飞行时间830h）。和无飞行经验年龄相仿的对照组人员（丙组）进行复查。结果与5年前MRI结果比较，每组的椎间盘突出数增加，但丙组的骨赘、老飞行员的椎管狭窄数明显增加。与5年前比较，老飞行人员与丙组间的MRI差别降低。结论战斗机飞行员的椎间盘退行性病变的发展可能较早。但是，随着年龄的增加，与对照组的差别逐渐缩小。

Study on cervical spine degeneration in fighter pilots

Objective To evaluate cervical spine degeneration in fighter pilots.Methods Following-up MRI was performed on asymptomatic experienced military high performance aircraft pilots(group A,mean age 47;mean acculated flying time 2100 h;group B,Young military high performance aircraft pilots,mean age 27,mean accumulated flying time 830 h) and on age-matched controls without military flying experience.Results Compared with the baseline MRI 5 year earlier,there were significant increases in cervical intervertebral disk protrusions in all groups,in osteophytes in controls,and in spinal stenoses in experienced pilots.The difference between experienced pilots and controls was markedly reduced compared with that at baseline MRI 5 year earlier.Conclusion Military high performance aircraft pilots seem to be at increased risk of premature development of degenerative lesions of the same type as are seen in the aging population.With increasing age the differences between pilots and controls diminishes.
