Intramedullary Limb-Lengthening Systems

Intramedullary limb-lengthening systems (ILLS) have been introduced as an alternative to the circular external fixation to reduce complications and improve patient comfort. ILLS was designed to control the lengthening process using remote control technology. The electrical (FITBONE) and the magnetic (PRECICE) driven motorized intramedullary bone-lengthening nails were introduced. With these, conflicts with the first mechanically driven intramedullary bone-lengthening nail, which had challenges controlling the lengthening rate, and a relevant point of the treatment, were expected to be resolved.
