About this case
This patient was treated in the height increase (limb lengthening) group (cll precice) at the Dr. Donghoon institute (DALRI) in Seoul.
This is an alignment or limb-length correction, so the source record carries no centimetre gain; the result is read from the mechanical axis on the radiographs instead.
The series on this page contains 1 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.
The femur is wrapped in well-vascularised muscle, so the new bone usually consolidates faster than in the tibia and tolerates a larger gain per segment, at the cost of watching for knee stiffness and quadriceps weakness.
Timeline and how to read the radiographs
In deformity-correction cases the distraction phase is shorter than in height cases, because the goal is realignment rather than distance gained.
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.
