Vibration white finger (VWF), also known as hand-arm vibration syndrome (HAVS) or dead finger, is a secondary form of Raynaud's syndrome, an industrial injury triggered by continuous use of vibrating hand-held machinery. Use of the term "vibration white finger" has generally been superseded in professional usage by broader concept of HAVS, although it is still used by the general public. The symptoms of vibrating white finger are the vascular component of HAVS.
