[Triplane fractures of the distal tibia]

9 cases of Triplane fractures are presented. These are fractures of the distal tibial epiphysis in three planes. All our 9 patients were adolescents; their medial epiphyseal part was alreadY closed. Viewed on x-ray film, the Triplane fracture presents in the anterior-posterior view as an Aitken-II fracture, in the lateral view as an Aitken-I fracture. 7 of the 9 patients were operated, 2 had conservative treatment. The late results, after the growth period of the patients had ended--on the average, after 5 years-are presented. On the strength of these results, we recommend open reposition and careful osteosynthesis of these fractures with the aim to reconstruct perfect articular congruity.
