Excision of an epiphysial cartilage for the arresting of growth is not a new surgical procedure. As early as 1873, such an operation was performed by Ollier1 for the correction of deformities caused by unequal rates of growth in the bones of the forearm and the leg. He did not, however, advocate this procedure for the equalization of length of the leg.
In 1933, Phemister2 published his paper on "Operative Arrestment of Longitudinal Growth of Bones in the Treatment of Deformities," in which he emphasized the value of this operation on the lower femoral and upper tibial epiphysial cartilages in treating unequal length of legs in growing children. Many surgeons, ourselves included, have adopted the method of Phemister because of its simplicity and because it is a generally applicable procedure for children during the period of growth. In performing the operation, however, we have not found the straight
