Blocking screws tibial nail
WebWe found that valgus deviation does occur during tibial lengthening using the LON technique, but that blocking screw placement may help to minimize the likelihood that severe valgus deviation will occur. Future prospective studies should be conducted to confirm this preliminary finding. Level of Evidence Level III, therapeutic study.
