Hand-Arm Vibration Syndrome

We represent federal employees who have suffered a range of physical injuries and occupational illnesses. One of those injuries is hand-arm vibration syndrome (HAVS), which includes damage to the hand, arm and fingers caused by vibration. Vibration injuries can occur in any number of occupations, including construction work, engineering and dental care.

Prolonged vibration exposure is harmful to the hand and tissue. Years of vibration exposure can cause various types of hand problems, including loss of sensitivity, white fingers and decreased grip force in the hands. The development of these injuries can vary significantly between workers, with some suffering injuries after a few years and others working for decades without problems.

When vibration damage is fully developed, it’s irreversible. Cessation of exposure will not lead to recovery and a cure is not possible through medical or surgical means. Early detection is paramount to limit the damage. Short of quitting the job, changing work methods or tools used for the job may prevent additional injury.

Vibration injuries are divided into three disorders — neurological, vascular and musculoskeletal. There may be a single or multiple disorders present.

1. Neurological disorder

Early symptoms include tingling and/or numbness in hands and fingers. As the condition develops, this tingling can turn into impaired sensibility, limited dexterity or significant reduction in hand control (dropping things easily, difficulty inserting keys or pouring a drink into a glass). If fully developed, neurological vibration damage is irreversible, causing disability and work incapability.

2. Vascular disorder

This damage affects the capillaries (small blood vessels) in the hand and fingers, which constrict uncontrollably, temporarily closing off blood circulation. It results in whitening of the fingers or part of the hand, usually triggered by exposure to cold. This damage is also called “vibration-induced white fingers” or “secondary Raynaud’s disease.” During this whitening, the affected area becomes numb. When the blood circulation returns, there may be major discomfort (such as tingling and pain).

3. Musculoskeletal disorders

These disorders may consist of arthritis, tendonitis and changes in muscle fibers. The damage can result in impaired grip force, reduced mobility and pain in the hand and arm. The reduced grip strength in the hands may be hard to explain, but a probable cause is damage to nerves and muscle structures. The muscle volume often is intact, but microscopic studies of muscle fibers may show a significant change in the fibers’ cross-sectional areas.
