A case Salter-Harris type-III fracture of the distal femoral epiphysis is reported. A 12 year-old boy was fractured during skiing. As the fractur did not reduce after the injury, initial routine X-rags were taken studied. We reduced the fracture, and immobilized it for 6 weeks using a plastic cast. The epipyseal line was obserred in X-rags for 5 months, after which the fracture healed satisfactorily.
