Remotely controlled motorized limb lengthening nails were first developed by Baumgart and Betz in 1992. Two devices are now FDA approved in the United States: the FITBONE® (Orthofix® International, Curaçao, Netherlands Antilles) and the PRECICE® (Nuvasive, San Diego, USA) nails, controlled by external signals (radiofrequency and magnetic, respectively).  Motorized internal limb lengthening is now established as a safe and reliable technique, relying on sufficient training of the surgeon and education of the patient. This review discusses the most common pediatric applications for the lower limb including patient indications, preoperative planning, surgical steps, pearls, and pitfalls.
