Fractures Involving the Distal Epiphyseal plate of the femur.
Forty-two fractures involving the distal femoral epiphyseal plate in 41 patients were reviewed. The average age at injury was 11.2 years. The follow up period ranged from one year to 20.3 years, with an average of 6.3 years. The Salter-Harris classification of epiphyseal plate injures proved to be a good indicator of the mechanism of injury and prognosis. Using stringent criteria to classify the end results, 2 out of 3 of the total group and 3 out of 4 of 29 Salter-Harris Type I and Type II injuries had good or excellent results. Type V crushing injuries of the growth plate, open injuries, fractures caused by high velocity motor vehicle accidents with severe displacement or multiple associated fractures, and incompletely reduced epiphyseal injuries gave only poor or fair results. Major problems responsible for poor or fair results were varus or valgus angulation, loss of joint motion and shortening due to premature epiphyseal closure. Orthoradiographs revealed the presence of some degree of shortening in 20 of 29 Salter-Harris Type I and Type II injuries which averaged 1.0 cm, but was of no clinical significance in most patients. These injuries must be reduced accurately. In the Type II epiphyseal separations unsatisfactory results were due to inadequate reduction or to associated injuries.
