ISKD Internal Bone LengthenerShawn 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.

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.

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.

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.
