The purpose of this study was to make a direct comparison between lumbar spine radiographs of incoming college football players and of an age-matched control group to determine whether there is a higher prevalence of lumbar spine abnormalities in football players before competing at the Division I level. We reviewed 187 lumbar spine radiographs. Of these, 104 were taken as a standard part of the preparation physical examination for incoming college football players. The remaining 83 radiographs were taken during routine preemployment physicals at a local factory. Each radiograph was read independently by three separate orthopaedic radiologists in a blinded fashion. Data were collected and statistically evaluated for 13 variables. The rate of spondylolysis was only 4.8% in our group of athletes and 6.0% in the control group (not significantly different). Only in the category of degenerative changes was a significant difference found. The control group had a 16.9% incidence of disk space narrowing and spurring and the football players had a 6.7% incidence. The remainder of the variables were not significantly different between the two groups. Our findings differ from previously published reports and indicate that football players entering college at the Division I level may have a similar prevalence of radiographic lumbar spine abnormalities, including spondylolysis and spondylolisthesis, as age-matched controls.
本研究的目的是对即将入学的大学橄榄球运动员与年龄匹配的对照组的腰椎X光片进行直接比较，以确定在一级联赛参赛前，橄榄球运动员腰椎异常的患病率是否更高。我们回顾了187张腰椎X光片。其中，104张是即将入学的大学橄榄球运动员准备体检的标准项目。其余83张X光片是在当地一家工厂的常规入职体检时拍摄的。每张X光片由三位独立的骨科放射科医生以盲法独立阅读。收集了13个变量的数据并进行了统计评估。我们的运动员组中椎弓根峡部裂的发生率仅为4.8%，对照组为6.0%（无显著差异）。仅在退行性改变类别中发现了显著差异。对照组椎间盘间隙变窄和骨刺的发生率为16.9%，而橄榄球运动员的发生率为6.7%。两组之间其余变量无显著差异。我们的研究结果与之前发表的报告不同，表明进入一级联赛大学的橄榄球运动员腰椎X光异常（包括椎弓根峡部裂和椎体滑脱）的患病率可能与年龄匹配的对照组相似。
