Abstract
1. Full recovery after fracture of the head of the radius in children may be expected in cases with tilting of the radial head from 30 to 60 degrees, whether treated by early manipulative or by operative reduction.
2. Manipulative reduction is facilitated by knowledge of the direction of displacement and tilting of the radial head, which can be determined by the study of appropriate radiographs.
3. When the upper radial epiphysis is completely displaced from the shaft, some permanent loss of movement is to be anticipated even when accurate reduction has been secured by operation. Early fusion and some deformity of the radial head are also to be expected. This is not surprising in view of the risk to the blood supply of the displaced head, particularly in those cases treated by operative reduction.
