Hand arm vibration syndrome




Historical perspective
Dr Maurice Raynaud described in 1862 a condition without any apparent cause, where one or more fingers of the hand became cold, pale and the skin assumed a white colour.

A description of the medical condition
This is a grouping of symptoms so called as it recognises that symptoms other than ‘white finger’ may occur following exposure to vibration.

Medical causation issues
Medical Examinations and the Classification of Vibration White Finger. The classification is on a sliding scale first recognising by the TAYLOR PELMEAR scale devised and published in 1975.

Date of knowledge
1976 is generally regarded as the date by which employers should have been aware of the effects of vibration on those exposed at work.

Regulations and breach of duty
1975: British Standards Institute published DD43 ‘Guide to the Evaluation of Exposure of the Human Hand/Arm System to Vibration’.

Limitation
The case handler is referred to the general section on limitation which precedes this section and where specific reference is made to vibration white finger.

Quantum
Judicial Studies Board Guidelines. The top of the bracket would normally represent the most disabled stage, 3 or 4 on the Taylor Pelmear Scale.

Apportionment and contributions
To establish liability, the claimant needs to establish that a particular employer’s tortious conduct made a material contribution to the claimant’s injury.
