ISKD Internal Bone Lengthener

• Shawn Volpe

What is ISKD?

• Intramedullary Skeletal Kinetic Distractor
• A rod inserted into the bone to gradually
  lengthen the bone.
• It is designed to lengthen a predetermined
  distance.
• Can lengthen as far as 8 cm.

3
Lengthening Process

• The lengthening is triggered by movement of the
  limb.
• Rotation of 3-9 degrees and minor weight bearing
  causes expansion.
• The distal end of the rod telescopes outward.
• A internal threaded rod spins causing the
  extension.

4
Benefits

• Completely internal and non-visible.
• No risk on infection
• Minimal scaring
• No social stress
• Much less painful then tradition lengthening
  methods.
• Hand-held monitor allows patient to follow
  lengthening process daily.

5
Progress Monitoring

• A hand-held console is given to the patient.
• A magnetic sensor allows the patient track there
  progress.
• Can be attached to a printer to print the data or
  sent to a PC with the ISKD program.
