About this case

This patient was treated in the congenital & paediatric conditions group (recurrent patella dislocation) 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 2 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.

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.
