Twenty-eight patients with injuries involving the epiphyseal plate were treated during these past seven years in our hospital. Twelve patients out of the twenty-eight were followed-up for one year and their prognosis concerning growth disturbance was studied.The following results were obtained:1. Twenty patients (71 per cent) were classified as Type II according to the Salter-Harris classification, seven (25 per cent) as Type I and one (4 per cent) as Type IV.2. The majority of upper extremity injuries were reduced by closed manipulation. Lower extremity injuries almost all required open reduction.3. The prognoses of upper extremity injuries were clinically good, whether they were treated by close or open reduction.4. All of the three patients with lower extremity injuries needed open reduction. The patient with distal femoral epiphyseal injury had a length discrepancy of 3.0 centimeters, all three patients had premature cessation of growth plate and two patients had valgus deformity.
