The purpose of this study was to determine the incidence and severity of degenerative changes seen on lateral roentgenograms in 200 asymptomatic men and women in five age groups with an age range of 20-65 years and to determine the normal values of cervical lordosis and spinal canal sagittal diameters and their relationship to degenerative changes. It was found that by age 60-65, 95% of the men and 70% of the women had at least one degenerative change on their roentgenograms. A small sagittal diameter correlated with the presence of degenerative changes at the same disc level, and the strongest correlation was with the size of the posterior osteophytes at C5-6 (r = 0.52). Cervical lordosis measurements did not relate to degenerative changes except for subjects over age 50 with moderate or severe intervertebral narrowing. It is important to realize that although roentgenographic abnormalities represent structural changes in the spine, they do not necessarily cause symptoms.
本研究的目的是确定200名年龄在20至65岁之间、分五个年龄组的无症状男性和女性的腰椎侧位X线片上退行性改变的发生率和严重程度，并确定颈椎前凸和椎管矢状径的正常值及其与退行性改变的关系。研究发现，到60至65岁时，95%的男性和70%的女性在其X线片上至少有一处退行性改变。较小的矢状径与同一椎间盘水平退行性改变的存在相关，最强的相关性是与C5-6处后骨赘的大小相关（r = 0.52）。除了50岁以上有中度或重度椎间盘狭窄的受试者外，颈椎前凸测量值与退行性改变无关。必须认识到，虽然X线异常代表脊柱的结构变化，但它们不一定会引起症状。
