Tibial lengthening using a new extension device. Report of thirty-two cases.

Using a new type of external fixation device for lengthening the tibia, lengthenings of from 3.5 to 6.5 centimeters were accomplished in thirty-two children, eight to seventeen years old, the six complications, none of which jeopardized the result. The procedure was painless and the patients were ambulatory on crutches two to three days after operation, while lengthening was continued as an out-patient procedure.
