Fractures of the scaphoid.

Fracture of the scaphoid is the most common injury of the carpus. Inadequate treatment frequently leads to non-union, which causes pain and serious disability. In the present study 134 scaphoid fractures treated during the period 1961-70 are reviewed. In fresh fractures less than 4 weeks old, bony union occurred in 95% with proper conservative treatment. The vexed question of whether a high or low circular cast should be used may not really be so important. In the present study, both methods of external splintage have given favourable results. It is indisputable, however, that other factors, such as the age of the fracture, its type and location are of great importance for the final result. It was also found that fracture dislocation greater than 1 mm regularly led to pseudarthrosis. Operative treatment is suggested in these cases, and the Matti-Russe technique has proved to be an excellent method for treatment of pseudarthrosis of the scaphoid. The study further confirmed that fractures of the scaphoid in children are more common than is usually supposed. They were all located in the distal two-thirds of the bone and it is suggested that this pattern of distribution is typical of childhood.
