ISKD Intramedullary Skeletal Kinetic Distractor

Anatomical site:         Femur, tibia

Procedure:                  Lengthening

Product description

The ISKD is a unique concept in limb reconstruction that has greatly improved the potential to lengthen limbs. The ISKD combines the advantages of intramedullary stabilization with the mechanics of external distraction in one device, offering the ability to lengthen up to 8 cm with a simple nailing technique.
Implanted after osteotomy, the ISKD lengthens gradually in response to normal movements of the limb.


Features & Benefits

The ISKD is designed to distract when rotation occurs at the osteotomy site. Because the ISKD is completely internal, the potential risk of infection is reduced compared to lengthening procedures that require external pins or wires. In addition, there is no scarring from pins moving through the soft tissues. The ISKD is designed to lengthen for a predetermined distance and then stop. The pace and the overall lengthening obtained can be tracked by using a dedicate handheld monitor with possibility of printing the data. A range of sizes are available to offer lengthening for most patients.

Surgeon Benefits

  • Lengthening with a simple nailing technique
  • Gradual callus distraction provides a natural lengthening process
  • Lengthening in cases of congenital shortening
  • Mechanical alignment and stability is maintained during lengthening and throughout consolidation

Patient Benefits

  • No risk of pin-tract infections
  • Hand held monitor allows patients to follow their lengthening process
  • As it is completely internal, the potential risk of infection is reduced
  • Internal device reduces psychological and social stress
  • Less painful than other lengthening methods
  • Minimal scarring


The ISKD is indicated for limb lengthening of the tibia and femur.
