Vibration white finger.

Nineteen consecutive patients claiming compensation for vibration white finger were reviewed. The cold provocation test was found to be of no value in confirming a diagnosis of vibration white finger. Small cysts were apparent on the radiographs in 61% of patients' wrists but none had developed significant degenerative changes of the wrist or digits. In this group of claimants, 63% had carpal tunnel syndrome on nerve conduction studies.
