Vibration white finger, also known as hand-arm vibration syndrome (HAVS), is a condition that affects individuals who repeatedly use vibrating tools or machinery. It is classified as an occupational disease that primarily affects the fingers, hands, and arms.
The term "vibration white finger" originates from one of the most common visible symptoms of the condition, which is the whiteness or blanching of the fingers. This occurs due to the constriction of blood vessels caused by the continuous exposure to vibrations.
The condition is caused by long-term exposure to excessive vibrations, typically from tools such as jackhammers, chainsaws, power drills, and pneumatic drills. The continuous exposure leads to damage in the nerves, blood vessels, and muscles of the hands and arms.
Symptoms of vibration white finger include initial tingling and numbness of the fingers, loss of manual dexterity, aches, and a white or bluish discoloration of the fingers (known as Raynaud's phenomenon). In severe cases, individuals might experience permanent damage to the affected areas.
Prevention and management of vibration white finger involve reducing exposure to vibrating tools through proper training, the use of anti-vibration gloves or tools equipped with vibration-reducing technology, and regular breaks during work. Detecting and addressing the condition early on is crucial in preventing further damage.
Individuals affected by vibration white finger should seek medical attention to receive a proper diagnosis and appropriate treatment, which may include lifestyle changes, anti-inflammatory medications, physiotherapy, and sometimes surgical interventions.
