Distal tibial and fibular epiphyseal fractures in children: prognostic criteria and long-term results in 158 patients.

From 1974 to 1993, 158 injuries of the ankle joint were treated at the Department of Orthopedics and Traumatology of Santobono Children's Hospital. One hundred thirty-two patients were treated conservatively; 26 patients underwent surgical treatment. Fibular fractures of the malleolus without epiphyseal separation or dislocation (68 patients) were excluded from this review. Of the 158 patients, 113 (70%) were available for follow-up. The mean age of patients was 11 years. The mean follow-up was 6 years (range 3-15 years). In this review, the authors compare, based on the degree of epiphyseal separation or dislocation, the Carothers-Crenshaw classification, which is based on the mechanism of trauma, with the Salter-Harris classification, which is based on anatomical-radiographic criteria. The aim is to review the authors' patients based on these classifications, to verify the prognostic ability of these criteria and thus to establish a better and more viable treatment for these injuries. Therefore, two fundamental factors should be considered for the prognosis: the mechanism of trauma and damage to the epiphyseal plate. Compressive trauma and adduction-supination trauma are the most dangerous types of injury, and any damage or gap in the physis should be perfectly reduced, by open means if necessary, to prevent a bone bridge from forming.
