How long does limb lengthening surgery take to work for limb length discrepancy?

During surgery, the bone is carefully divided and an internal or external device is used to maintain alignment. After an initial healing period, the device is adjusted gradually so new bone can form in the gap. This is followed by consolidation, when the new bone becomes stronger. The time varies with the bone involved, the size of the discrepancy, bone quality, age, the device, and how well the surrounding muscles and joints respond. Equal limb length is only one goal; comfortable movement and safe function matter too.

Attend imaging and adjustment appointments on schedule, and follow weight-bearing instructions closely. Physiotherapy helps preserve movement in nearby joints, maintain muscle control, and retrain walking as the limbs become more balanced. Check the skin and any pin or incision sites as instructed. Do not change the device settings, exercise load, or walking aid without guidance from the treating team.

Seek prompt advice for increasing pain, new numbness, weakness, loss of movement, or a sudden change in limb alignment. Report redness, swelling, warmth, drainage, or fever around a wound or pin site. Urgent assessment is needed for a cold or pale foot or hand, severe swelling, or pain that is rapidly worsening despite the prescribed plan.

Which stage am I in, and what finding will show that the new bone is ready for more loading? What walking aid and weight-bearing level should I use? How will you measure function as well as limb length, and what symptoms should trigger an earlier review?
