Vibration white finger

Vibration White Finger (VWF), also known as Hand-Arm Vibration Syndrome (HAVS), is a secondary form of Raynaud's disease, an industrial injury triggered by continuous use of vibrating hand-held machinery. This condition affects the blood vessels, nerves, muscles, and joints of the hand, wrist, and arm.

Symptoms

The symptoms of Vibration White Finger are the sensations of tingling (paresthesia), numbness, and a loss of strength in the hands. The fingers, particularly the tips, become white and start to ache when exposed to the cold or when the hands are in use. As the condition progresses, the symptoms can become constant, affecting sleep and everyday activities.

Causes

Vibration White Finger is caused by prolonged use of vibrating hand-held machinery, such as power drills, chainsaws, and pneumatic drills. The vibration damages the small blood vessels in the fingers, leading to a lack of oxygen and nutrients to the tissues, causing the symptoms of VWF.

Prevention and Treatment

Prevention of Vibration White Finger involves reducing exposure to vibration. This can be achieved by using anti-vibration gloves and tools, taking regular breaks from vibrating machinery, and keeping hands warm and dry. Treatment for VWF includes medication to improve blood flow, physiotherapy, and in severe cases, surgery.
