[Axial and derotational traction before surgery for slipped femoral capital epiphysis].

18 cases of slipped femoral capital epiphysis were prepared for surgery by axial and derotational traction lasting 1 to 5 (av. 2,9) weeks. In all cases significant pain relief was achieved, partially the range of passive motion in the hip was improved. No reduction of slipped epiphysis was recorded. Best results occurred in medium and severe (> 60 degrees) cases. The traction before surgery for slipped femoral epiphysis is considered to improve range of motion, bring good pain relief, but not reduce the slipped epiphysis.
