Definition - What does White Finger mean?
White finger is discoloration of the extremities, particularly the fingers and toes. This discoloration is the result of reduced blood flow to these areas. The affected areas become purple or white, hence the term white finger. White finger often occurs in forestry workers and cold store employees, as prolonged times in cold temperatures can cause the heart to slow the pumping of blood through the body. It is also known as Raynaud’s Syndrome.
