Abstract
1. The cases of four children who presented with bowing or pseudarthrosis of the fibula only, are described.
2. There is a gradation in the severity and significance of this condition. There may be fibular bowing without fibular pseudarthrosis; fibular pseudarthrosis without ankle deformity; fibular pseudarthrosis with deformity but without the late development of tibial pseudarthrosis; or fibular pseudarthrosis with the late development of tibial pseudarthrosis.
3. Proper management is dependent on a knowledge of this range of conditions.
