Fracture of the carpal scaphoid in children. A clinical and roentgenological study of 108 cases.

A series of 108 carpal scaphoid fractures in children was analysed with respect to the site, type and treatment of the fracture. The patients were followed until radiological fusion occurred. All fractures united and healed completely with conservative treatment. Ninety-four fractures, 41 of which were avulsions, were located in the distal third of the scaphoid. There were 13 waist fractures, and one avulsion fracture was located in the proximal pole of the scaphoid. The great number of avulsion fractures and the location of the fractures in the distal third of the scaphoid is very typical in children. In three neglected cases marked bone resorption was seen on the fracture surface 3 weeks after the injury. Because non-union is possible especially in neglected cases of waist fractures, control radiographs should be taken 1 or 2 weeks after the injury if the fracture is not visible on the primary radiographs but is suspected clinically. Immobilization with an adequate plaster cast is mandatory in all transverse fractures of the carpal scaphoid in children.
