Summary

This prevention pamphlet is for workers who use portable vibrating tools or certain manual tools, and for employers and the occupational health and safety committees in their organizations.

Hypothenar Hammer Syndrome is an insidious disease that can be easily confused with others that also cause the fingers to blanch. Two other diseases sharing that symptom are hand-arm vibration syndrome (another occupational disease) and Raynaud’s disease (which is hereditary).
