A survey of the incidence of white finger syndrome (WFS) in forestry workers was conducted. The cohort consisted of 606 persons employed as forestry workers in 29 departments in France. They completed a questionnaire to obtain information on power saw use, occupational history, presence or absence of WFS, and details about WFS if present. A total of 252 subjects, 41.58 percent, reported WFS. Fingers on the left hand were more frequently affected than fingers on the right hand. The incidence of WFS increased with years of power saw use. The incidence was similar to that seen in forestry workers in England and the Scandinavian countries. The incidence of WFS was also correlated with hours of daily use of power saws. For subjects who used power saws at least 5 hours a day for over 10 years the frequency of WFS was significantly associated with the weight of the saw. There was no correlation of WFS frequency with saw weight for subjects who had used power saws for less than 6 years regardless of the hours of daily use. The authors conclude that WFS occurs among French forestry workers using chain saws with about the same frequency as it does in England or the Scandinavian countries. The incidence of WFS is strongly linked to years of exposure and hours of daily use. The characteristics of WFS do not appear to depend on geographical area, work practices, or type of forest.
