Forty-three former players for the National Football Team of Norway were examined clinically and radiologically for degenerative changes in the cervical spine. Compared with men of the same age groups the onset of degeneration was 10-20 years earlier and the frequency of degeneration was significantly higher. Degenerative changes were not especially high in “headers”, but this group had a higher frequency of subjective complaints and clinical findings such as reduced cervical movements.
对43名挪威国家足球队的前队员进行了颈椎退行性变的临床和放射学检查。与同年龄组的男性相比，退变的发生提前了10至20年，且退变频率明显更高。在“头球运动员”中，退行性变并不特别高，但该组主观症状和临床体征（如颈椎活动度降低）的发生率较高。
