The term ‘Hand-arm vibration syndrome’ refers to the group of symptoms that can occur from using vibrating tools and equipment. These symptoms include, white finger, carpal tunnel syndrome, musculoskeletal injuries and vascular injuries.
Examples of the equipment than can cause HAVS include, chainsaws, road breakers, hammer drills, hand-held grinders, jigsaws, polishers, powered lawn mowers and powered sanders.
Musculoskeletal injuries include bone cysts and osteoarthritis. These can cause chronic pain, impaired grip force and reduced mobility.
Vascular injuries due to HAV often cause the capillaries in the hand and fingers to constrict, restricting blood circulation. This can result in skin blanching, numbness, tingling and pain. As the condition worsens, the blanching can spread down the fingers, which is why this symptom is often referred to as ‘vibration white finger’. In severe cases, the reduced blood supply causes gangrene leading to the loss of fingers.
Neurological injuries are the result of damage to the nerves and senses, which can cause tingling or numbness in the hands or fingers. A Long-term injury that limits your ability to feel textures or temperatures and affects dexterity.
