The X-ray findings of the lumbar spine in the preemployment examination of 807 lumbermen are presented. From the applicants 11.4% were rejected because of roentgenological and/or clinical low back abnormalities. The youngest age group showed a high frequency of spondylolisthesis (8%). The possible role of heavy work in adolescence in the etiology of spondylolisthesis is discussed.
