Abstract

Twenty-one supracondylar femoral and 11 tibial derotation osteotomies were performed in 17 patients to correct rotational deformities. Three different methods were used to fix the fragments after derotation: pins incorporated in plaster, plate and screws, and the Ilizarov external fixator. A retrospective review showed no difference in accuracy of derotation between the three methods. However, we recommend the use of the external fixator because it gives less malunion and permits early mobilization and (partial) weight bearing.
