About this case
This patient was treated in the height increase (limb lengthening) group (cll + deformity correction) at the Dr. Donghoon institute (DALRI) in Seoul.
The record states 5 cm of lengthening but no before/after height, so only the verified figure is shown.
The series on this page contains 4 images, in the order the hospital published them.
Technique and segment
The source record does not name the technique used here. The choice between an external frame, an internal nail, or a hybrid depends on the segment, the target length, and each patient's soft-tissue condition.
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 5 cm gained here corresponds to roughly 67 days of distraction — about 2 months — before the consolidation phase begins.
The source record does not state the follow-up month. Lengthened bone typically consolidates fully around 12-18 months after surgery.
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.
