LON
Lengthening Over Nail
A hybrid technique: external fixator drives distraction while an internal nail provides stability — fixator removed earlier than classical Ilizarov.
LON (lengthening over nail) is a hybrid limb-lengthening method: an external fixator pulls the bone apart while an intramedullary nail sits inside it. Once the target length is reached, the nail is locked and the frame comes off within weeks. It suits cost-conscious cosmetic patients who accept a short frame period; most Turkish clinics listed here offer it.
How it works
LON (Lengthening Over Nail) combines an external fixator with an intramedullary nail. The external frame distracts the bone; once the target length is achieved, the fixator can be removed and the internal nail alone supports consolidation. This shortens fixator time vs. pure Ilizarov, reducing infection risk and improving comfort.
Schematic. Bone geometry and hardware placement are illustrative; consult your surgeon for procedure specifics.
How does lengthening over nail work?
Everything happens in one operation. The surgeon cuts the femur or tibia, slides an intramedullary nail down the canal, and builds an external fixator around the limb in the same sitting. The nail is left unlocked at one end so the bone can slide along it. From then on the frame does the work: you turn it in small steps, the bone ends move apart at about 1 mm a day, and new bone fills the gap. During this phase the nail is only a rail.
When the target length is reached, the surgeon locks the nail with screws and removes the frame. That is the point of the method. The nail holds the soft new bone while it hardens, so you are not living inside a frame for the months of consolidation that classical Ilizarov demands.
Dror Paley's group described the technique in 1997 in 32 femora. Compared with matched Ilizarov cases, lengthening over a nail cut time in external fixation by almost half, and knee motion returned to normal 2.2 times faster. The nail itself usually comes out in a later, smaller operation.
Who is LON for?
LON is for the cosmetic patient who wants to pay less than a magnetic nail costs and spend less time in a frame than Ilizarov requires. That trade is why it is the method most Turkish clinics in this directory quote first, and why it is common in India.
It is also the second-largest group in the evidence. In the Marwan 2020 systematic review of cosmetic stature lengthening, 253 of 795 patients (31.8%) were lengthened over a nail; only classic Ilizarov had more.
Not everyone is a candidate. The canal has to be wide enough to take the smallest available nail, and a straight nail cannot fix a bent bone, so a marked deformity that needs gradual correction rules the method out. The 2013 randomised trial that compared LON with conventional Ilizarov used exactly those two criteria to exclude patients, along with a history of bone infection. If a clinic offers LON without looking at an X-ray of your canal, that is a gap in their screening.
What does the LON protocol look like?
Distraction starts after a short latency, at roughly 1 mm a day split into several turns, the rhythm Ilizarov's own experiments found gave the best bone. Typical cosmetic gains are 5–8 cm; the LON series in the Marwan review averaged 6.8 cm.
Frame time is what separates LON from Ilizarov. The review's LON series spent a mean of 17.4 days in the fixator per centimetre gained, against 42.5 days per centimetre for the classic frame. At that rate a 6 cm lengthening means roughly 15 weeks in the frame. The 2013 randomised trial recorded a mean of 52.2 days of external fixation for LON versus 180.4 days for conventional Ilizarov, at gains of 4–5 cm.
While the frame is on, pin sites need cleaning every day. After it comes off, the bone still has to consolidate on the nail, which is why the recovery window on this page runs to 16–28 weeks and why crutches continue well past frame removal.
What are the risks of LON?
Pin-site infection is the defining risk of every method that uses a frame. Pin-track complications are described as an almost universal finding with external fixation, and in LON the frame is on for weeks, so expect at least minor pin-site trouble.
LON adds a risk the frame-only methods do not have. The pins pass through skin and bone in the same segment that holds the nail, so a pin-site infection can track inward and become a deep intramedullary infection. In the 2013 randomised trial, 3 of 15 LON limbs (20%) developed deep infection and none of the 16 conventional limbs did; the authors note that earlier LON series reported 0–15%. Paley's original protocol told surgeons to keep pins and nail from touching for this reason. Ask any clinic how they do that.
The rest of the list is shared with all lengthening: nerve irritation, joint stiffness, ankle equinus, slow or bent regenerate. In the Marwan review, LON had the highest mean number of problems per patient (1.1) but a low complication count (0.1); none of the between-method differences reached statistical significance.
Where does LON sit on cost?
Between the two extremes. An Ilizarov frame is the cheapest hardware in lengthening; a magnetic nail is the most expensive implant. LON uses a standard interlocking nail plus a frame, so its implant bill sits well below PRECICE while the extra hardware puts it above a plain Ilizarov build. Paley's 1997 comparison found the cost of treatment higher for LON than for the matched Ilizarov cases, even though frame time was halved.
What changes the total is not the hardware. It is theatre visits and time. LON involves the main operation, a frame-removal-and-locking procedure, and nail removal later. Some clinics bundle all three; many bundle only the first. Turkish packages typically fold in the hospital stay and some in-house physiotherapy, which is why a headline number can look low next to a Western quote that itemises everything.
This page carries no prices on purpose. The cost guide and each clinic listing do, and they are updated separately.
How to read a clinic that offers LON
Start with volume and outcomes, in that order. Ask how many LON cases the lead surgeon did last year and how many deep infections that produced; a surgeon who tracks the second number is the one you want. Ask how they keep pins clear of the nail. Ask when the frame comes off: the honest answer is weeks after distraction ends, not months.
Then ask about the pieces the brochure skips. Who cleans and checks your pin sites once you fly home? How many operations are in the quote: the lengthening, the frame removal, the nail removal? Is the nail a standard interlocking nail, and is its removal priced?
Finally, ask what else they offer. A clinic that only does LON will recommend LON. A clinic that also places internal nails and still recommends LON for you is giving you a judgement, not a sales pitch. Clinic profiles on this site list which methods each centre performs; use that filter first.

Frequently asked questions
How long is the external fixator on with LON?
Weeks, not months. The frame stays on only for distraction, then the nail is locked and the frame removed. In the Marwan 2020 review, LON series averaged 17.4 days in the fixator per centimetre gained, so a 6 cm lengthening means roughly 15 weeks; the 2013 randomised trial recorded a mean of 52.2 days at gains of about 4 cm. Classic Ilizarov keeps the frame on through consolidation as well, typically two to three times longer.
Is LON safer than the Ilizarov method?
It trades one risk for another. LON shortens frame time, which lowers the exposure to pin-site problems; in Paley's 1997 comparison all six refractures occurred in the Ilizarov group and none in the LON group. But it adds deep intramedullary infection, because pins and nail share the same bone: 3 of 15 LON limbs in the 2013 randomised trial, none in the conventional group. Overall complication counts in that trial favoured LON. Surgeon technique decides which side of that trade you land on.
Is LON cheaper than PRECICE?
Yes, on hardware. LON uses a standard interlocking nail and a ring frame, while PRECICE is a magnetically driven motorised implant with a much higher unit price. The saving is partly offset by the frame phase, pin-site care and a frame-removal procedure. This page does not list prices; the cost guide and the individual clinic listings do, and the difference between markets is larger than the difference between methods.
Can LON be done on the tibia as well as the femur?
Yes. Paley's original 1997 series was femoral, but tibial LON is well described: Chaudhary's Indian series of 27 procedures covered 22 tibiae and 5 femora, with a mean gain of 4.6 cm and external fixation of 17.8 days per centimetre. The tibia tolerates less length than the femur and the ankle is prone to equinus, so tibial protocols lean harder on physiotherapy and foot positioning while the frame is on.
What is the difference between LON and LATN?
The order of the nail. In LON the nail is inserted at the first operation and the frame lengthens the bone over it; the frame comes off when distraction ends. In LATN (lengthening and then nailing) the frame lengthens the bone alone and the nail is inserted at a second operation, at which point the frame is removed. LON means fewer operations; LATN keeps metal out of the canal while the pins are in.
