Why Time Matters in Bone Transport
Bone transport surgery is a proven technique to correct limb length discrepancies, bone defects, and deformities. While patients are reassured by its effectiveness, the most common question is:
👉 “ How long does bone transport take?”
The answer isn’t the same for everyone – it depends on the size of the bone gap, the patient’s healing rate, and the type of fixator used. Let’s break it down step by step.
What is Bone Transport in Limb Lengthening?
Bone transport is a method in which a controlled cut is made in the bone, and with the help of an external fixator (such as an Ilizarov frame), the bone is gradually moved to close a gap or increase its length. Behind the moving bone, new bone forms naturally, eventually restoring both length and strength.
The Timeline of Bone Transport
1. Latency Phase (5–7 days)
- After surgery, there is a short rest period before movement begins.
- This allows initial healing and prepares the bone for gradual distraction.
2. Distraction Phase (1 mm per day)
- The bone is moved at a controlled speed, usually 1 mm per day.
- If a patient needs 6 cm of lengthening, it will take about 60 days just for transport.
3. Consolidation Phase (2–3 times distraction period)
- Once the bone has been moved into place, the new bone must harden.
- This can take 2–3 times longer than the distraction phase.
- Example: 6 cm distraction = 4–6 months of consolidation.
4. Fixator Removal
- When X-rays show the new bone is strong, the fixator is removed.
- The patient may use braces or crutches for some weeks after removal.
So, How Long Does It Really Take?
On average:
- Small gaps (3–4 cm): 4–6 months
- Medium gaps (5–8 cm): 6–10 months
- Large gaps (>10 cm): 12+ months
Every patient’s journey is unique. Children often heal faster, while adults may need more time.

Recovery Beyond Time
- Physiotherapy: Essential throughout the process to keep joints flexible.
- Nutrition: A diet rich in protein, calcium, and vitamin D supports faster healing.
- Commitment: Daily fixator adjustments and regular follow-ups are critical to success.

FAQs
How long does bone transport usually take?
It depends on the defect size. On average, 1 mm of transport is done per day, followed by a longer consolidation phase. A 6 cm lengthening can take 6–8 months in total.
Why does bone transport take so long?
Because the bone is moved gradually to allow new bone to form naturally. If done too fast, the new bone won’t have time to grow strong, increasing the risk of complications.
Is the process faster in children than adults?
Yes. Children’s bones regenerate more quickly, so both the distraction and consolidation phases are shorter. Adults usually take longer.
Can the bone grow faster than 1 mm per day?
In rare cases, doctors may increase to 1.5 mm per day, but going too fast risks weak bone formation. 1 mm per day is the safest and most reliable rate.
How painful is bone transport during limb lengthening?
Most patients feel mild discomfort during daily adjustments, but pain is well-controlled with medication. The body usually adapts within a few weeks.
What happens if the new bone doesn’t form properly?
If the regenerated bone is weak or thin, doctors may slow down the distraction or extend the consolidation period. In rare cases, bone grafting may be added.
Do patients need to stay in the hospital during the entire process?
No. After surgery, patients go home with the fixator and visit the clinic regularly for adjustments and X-rays. A hospital stay is usually only a few days.
Can patients walk with the fixator on?
Yes, most patients are encouraged to walk with partial weight-bearing soon after surgery. Walking actually helps bone formation and prevents stiffness.
Does everyone heal at the same speed?
No. Healing depends on age, nutrition, bone health, presence of infection, and patient commitment to physiotherapy.
Will the limb be as strong as normal after bone transport?
Yes. Once the new bone fully consolidates, it becomes as strong as natural bone, and patients usually return to normal activities, including sports.
