1. ISKD Internal Bone Lengthener
Shawn Volpe

2. 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.
