In recent years an increasing number of safety rules, safety devices, and regulations have been devised in industry to prevent injuries to the upper extremities. In addition, the prevention of accidents in children, about the household, and in farming communities has been given considerable publicity. However, in spite of the large number of precautionary measures that have been devised and advocated, these injuries still continue to be an important item in the daily practice of many surgeons. It is estimated that over 50% of the injuries in industry are injuries of the hand. Many of these are relatively minor, so that often only a few days to a week is lost from work. However, others are of such severity that a digit or even a hand may be lost, with resultant decrease in earning power for the wage earner, plus the necessity of many months and even years of rehabilitation.
