This case is of interest for several reasons:
1. It presents a rather unusual injury, with the distal femoral epiphysis displaced and united anteriorly to the metaphysis.
2. Although shortness of the extremity of one and one-half inches was present, it was possible to secure by operation an anatomical reduction with restoration of normal length.
3. The equality of the extremities was maintained by arresting the growth of the opposite distal femoral epiphyseal plate.
