Description
Can limb lengthening be done with less time in an external fixator?
In this video, we explain the LON Method (Lengthening Over Nail) — a technique that combines an external fixator with an intramedullary nail to make recovery faster and more manageable.
🦴 What is the LON Method?
LON stands for Lengthening Over Nail.
It combines:
⚙️ External Fixator → used during the active lengthening phase
🦴 Intramedullary Nail → placed inside the bone for internal stability
Both systems work together to safely lengthen the bone while improving recovery.
📊 How Does It Work?
Bone is cut surgically (osteotomy)
External fixator gradually lengthens the bone
Internal nail maintains alignment and stability
Once enough stability is achieved, the external frame can be removed early
⏳ Biggest Advantage: Reduced Treatment Time
Traditional external fixator treatment:
📅 ~7–8 months in frame
LON Method:
📅 ~2.5–3 months in frame
This significantly improves comfort and rehabilitation.
✅ Key Benefits of LON Method:
🦴 Better Bone Stability
Nail supports alignment internally
Reduces risk of deformity during consolidation
🚶 Early Frame Removal
Easier movement and rehabilitation
Improved quality of life during recovery
⚠️ Lower Pin Site Problems
Reduced duration of external pins
Lower infection and skin irritation risk
💪 Faster Return to Normal Activities
Earlier physiotherapy progression
Improved walking and daily mobility
📌 Important Insight:
Even though the frame is removed earlier, the bone still needs time to fully consolidate internally.
⚠️ Recovery still depends on:
Proper distraction rate (~1 mm/day)
Consistent physiotherapy
Maintaining range of motion
Regular X-ray monitoring
❌ What is risky / not recommended:
Rushing weight-bearing
Ignoring rehabilitation after frame removal
Prioritizing speed over bone quality
The LON method is one of the major advancements in limb lengthening because it combines the affordability of external systems with the stability advantages of internal fixation.
