Figs. 3-A and 3-B A patient with congenital femoral deficiency who had femoral lengthening with a motorized intramedullary nail.

Standing anteroposterior radiograph, made at the end of lengthening, demonstrates full correction of the limb-length inequality and excellent limb alignment.

Fig. 3-B.

After weight-bearing without crutches against medical advice, and then falling, the patient sustained a segmental fracture of the proximal part of the femur through the proximal locking bolt site, with telescoping of the lengthened segment. The patient underwent revision to a retrograde femoral trauma nail, with some loss of previously achieved length.
