摘要
目的评价歼击机飞行员腰椎退行性病变状况。方法对4年前作过CT检查的无症状歼击机飞行员(A组,平均年龄42岁,平均累计飞行时间2400h;B组,平均年龄27岁,平均累计飞行时间930h),和相应年龄无飞行经验的对照组人员(C组)进行复查。结果与4年前CT结果比较,各组的椎间盘突出数明显增加,而对照组的骨赘、A组老飞行员的椎管狭窄数明显增加。与4年前比较,老飞行人员与C组间的CT差别明显降低。结论歼击机飞行员腰椎退行性病变的发展较地面人员早。随着年龄的增加,与对照组的差别逐渐缩小。
Objective To investigate the characteristics of degenerative changes of lumbar spine in fighter pilots, Methods Sixteen elder pilots （Group A, average age 42）, 13 younger pilots （Group B, average age 27） and 15 elder ground personal （Group C, average age 43） served as subjects, CT of lumbar spine and follow up CT 4 years later were taken. The degree of degenerative changes was graded by the same specialist, and the data of two CT findings of three groups were compared statistically. Results As compared with degenerative change findings of initial CT, the incidence of disc herniation increased significantly in all 3 groups, the number of osteophytes significantly increased in group C and stenosis of spinal canal increased significantly in group A. The differences of CT degenerative findings between group A and group C became significantly less prominent in the follow up examination. Conclusion It is suggested that the degenerative changes of lumbar spine of fighter pilots occurred earlier than ground personnel. The differences of degenerative changes between elder pilots and elder ground personnel diminished gradually along with the aging.
