Limb Lengthening at Children’s National: Why Choose Us?

At Children’s National, we start working with children and their families at the first signs of a limb length discrepancy. Our orthopaedic experts have years of experience and are trained in all the latest limb lengthening techniques.

Highlights of our program include:

  • Advanced treatments: The only approved device of its kind, the PRECICE® nail works from within your child’s bone to add limb length. Children using the PRECICE® device often experience less discomfort and better joint mobility during limb lengthening, compared to traditional external frame devices.
  • Minimally invasive techniques: We use small incisions to access bones and low energy vibrations to carefully break them when necessary. Our approach minimizes disruption to muscle tissue and veins and lowers the risk of complications. Learn more about minimally invasive orthopaedic surgery.
  • Developmentally appropriate care: We use X-rays and special calculations to determine your child’s projected limb length difference at the time he or she stops growing. Using this information, we determine the best time in your child’s skeletal development for treatment. In some cases, it is best to delay treatment until your child is almost done growing.
  • Accuracy: We ensure the accuracy of your child’s treatment from the start with the help of special computer technology. If your child is receiving an external frame device, special software helps us pre-build the device before surgery and calculate the necessary daily adjustments to ensure equal limb length and bone alignment.
  • Family-centered care: We pride ourselves in getting to know our patients and their families. This helps us tailor care and treatments to meet each child’s unique needs.
