Prognosis of vibration induced white finger : a follow up study.
Objectives-To follow up 102 patients with vibration induced white finger (VWF).
Methods-102 subjects with VWF were reexamined one to 13 years after the condition had first been diagnosed.The decrease in systolic blood pressure in a finger during cold provocation (FSP%) was measured in the same finger at both examinations.
At the second examination, 22% stated that the frequency of attacks had decreased.
The improvement was most frequent in subjects with little or no exposure to vibration during the previous two years, in non-smokers, and in subjects without other circulatory diseases than VWF. 32% stated that the frequency of attacks had increased.
The number of finger phalanges that blanched on cooling averaged 15.8 at the first examination and 14.4 at the second examination.
Working with high vibration hand held tools during the previous two years was related to an aggravation, with more finger phalanges affected at the second examination.
Presence of other circulatory diseases had the same effect.
In nonsmokers the number of affected finger phalanges had decreased at the second examination.
The FSP% had increased (improvement) in 43%, decreased (aggravation) in 12%, and was unchanged in 45%.
