The vibration-induced vasospastic syndrome (VVS) is a secondary form of Raynaud's syndrome . Other terms are Traumatic Raynaud's Phenomenon , Traumatic Vasospastic Disease (TDV) or Vibration Induced White Finger (VWM) and Vibration Syndrome . The disease is recognized as an occupational disease under the designation BK 2104 .
Pathogenesis
Working for many years with vibrating equipment (see: Human vibration ) can lead to a temporary interruption of blood flow and the associated white discoloration of the fingers when exposed to cold. Chainsaw operators , cast cleaners and stone cutters are most commonly affected . Before the introduction of vibration dampers and handle heaters on chainsaws, this was a common illness of foresters . The cause is in particular vibrations with frequencies in the range of around 20 to 1000 Hz.
diagnosis
Diagnosing the disease in the symptom-free interval is difficult. The medical history ( anamnesis ) is important, especially regarding the working conditions. A provocation test (cold water test at 12 ° C) can cause the symptoms. Objectification is carried out by measuring the skin temperature, determining the rewarming time, pressing the fingernails and neurological examinations with testing of sensitivity , sensation of vibration and motor skills .
