We describe a case of irreversible severe vibration-white-finger (VWF) occurring in a male who used a compression-hammer daily at work for a 20-year period. Infra-red thermography following either a cold provocation or a vibratory stress was a sensitive objective method of documenting the condition. Persistent elevation of IgG anticardiolipin antibodies (aCL) was found in his serum and may be a marker of endothelial damage associated with either VWF or the patient's coincidental valvular heart disease.
