About this case
This patient was treated in the height increase (limb lengthening) group (cll precice) at the Dr. Donghoon institute (DALRI) in Seoul.
Height measured 177 cm before surgery and 186.8 cm once distraction was complete — a gain of 4.8 cm, as recorded by the hospital itself rather than estimated by us.
The series on this page contains 10 images, in the order the hospital published them.
Technique and segment
PRECICE is a fully internal magnetically driven nail: there are no pin sites to care for, which means less pain and a faster return to daily life, but it carries limits on body weight and on the maximum length per segment.
Lengthening the femur and tibia together gives the largest total gain and keeps upper- and lower-leg proportion balanced, but recovery and physiotherapy take clearly longer than a single-segment case.
Timeline and how to read the radiographs
At the standard rate of about 0.75 mm per day, the 4.8 cm gained here corresponds to roughly 64 days of distraction — about 2 months — before the consolidation phase begins.
This series was taken 14 months after surgery. The regenerate is fully consolidated, and this is the window in which hardware removal is considered.
Daily physiotherapy through the distraction phase is the single strongest predictor of the result: patients who stop stretching run into joint stiffness far more often than into problems with the bone itself.
