Limb lengthening with expanding intramedullary rods has become the standard of care for limb lengthening procedures. The procedure entails performing an osteotomy of the short bone and placing a mechanical expanding intramedullary nail. The aim of the study is to explore the role of ultrasound to measure tibia and femur lengthening procedures and compare the accuracy to standard radiographs.
The study design is a prospective, pilot study of 5 tibias and 5 femurs. Measurements of the femurs and tibias will be obtained in 3 separate locations to try to identify areas that can be visualized and measured by an ultrasound. The cost of the ultrasound will be compared to the cost of x-rays, and any pain regarding imaging modalities will also be compared
