Limb lengthening of the left leg is an orthopaedic operation that makes a short left thigh bone (femur) or shin bone (tibia) longer. The surgeon cuts the bone, fixes it with a motorised nail inside the bone or an external frame outside the leg, and then lengthens it by about one millimetre a day while new bone forms in the gap. The method is called distraction osteogenesis. It is used for a left leg that is shorter because of growth problems in childhood, an old fracture, infection, a congenital condition or a joint deformity. Orthopaedic departments in Turkey offer both nail and frame techniques, and the same operation is used whichever side is short: the surgeon lengthens the shorter leg, so for you it happens to be the left.
For the wider choice of bone and joint procedures see our orthopedics treatments in Turkey.
Many people have a small difference between their legs and never need treatment. Differences under about 2 cm are usually managed with a shoe insert or a built-up shoe. Surgery is normally discussed when the difference is larger, when it causes a limp, a tilted pelvis, back or hip pain, or knee problems on the longer side, or when a lift is not enough. A long-standing difference can also make the spine curve to compensate; that functional curve is different from structural scoliosis, which is covered in our guide to the operative treatment of scoliosis.
The decision rests on measurement. Your surgeon will ask for a standing full-length X-ray of both legs, sometimes a CT scan, and will check whether the shortening is in the femur, the tibia, the foot or the hip. The lengthening is planned on the bone that is short, and the angle of the joint is checked too, because a deformity may need correcting at the same time, as described under bone deformity correction surgery.
The operation follows a fixed sequence. Under general or spinal anaesthesia the surgeon makes a small cut in the bone through a short incision, leaving the surrounding tissue and blood supply as intact as possible. The nail or frame is then placed. After a rest period of about five to seven days, you or a physiotherapist start the daily lengthening: a frame is turned with a wrench several times a day, and a motorised nail is lengthened with an external magnetic remote control. New bone grows in the widening gap. When the planned length is reached, the new bone hardens and strengthens over several months, a phase called consolidation. Physiotherapy runs through all of it, because muscles and tendons must stretch with the bone. The whole sequence, from the cut to removal of the hardware, usually takes most of a year.
Both methods lengthen bone; they differ in comfort, control and risk. A nail is hidden inside the bone, so there are no pins crossing the skin, but it usually suits a bone of adequate width and a limited lengthening amount. A frame can handle larger or more complex corrections, including angled or rotated bones, but pins pass through the skin and need daily cleaning. For angled bones see our guide to deformity correction and limb lengthening.
| Method | Suits | Typical limits |
|---|---|---|
| Motorised intramedullary nail | Adults with a straight femur or tibia needing a moderate gain | Bone width and length of the nail limit the amount; costs more for the implant |
| External frame (circular or monolateral) | Larger gains, bones with angle or rotation problems, infection history | Pin-site care, scars and bulky frame for months |
| Lengthening over a nail | Shortening the time in the frame after the gain is done | Two hardware systems; needs a surgeon who does it regularly |
The principle is well established: distraction osteogenesis has been used for decades and the orthopaedic literature supports it as a way to equalise leg length. Most people achieve the planned length and report a more even walk. What is less certain is the details of any one case. Healing speed varies with age, smoking, general health and the cause of the shortening. Lengthening does not cure the cause of the shortening, so a hip or knee deformity may still need separate treatment. A trustworthy surgeon will give you a target length range and tell you which problems they cannot promise to remove.
How much length can the left leg gain? As a general guide, a single lengthening in one bone is often planned in the range of about 3 to 8 cm; larger gains are possible in some cases but carry more risk of stiffness and nerve problems. A larger difference may be spread over two bones or two stages. The amount that is safe depends on the bone, the muscles, the joint above and below, and how you respond during lengthening, so the surgeon revises the plan as the weeks go by. In children whose growth plates are still open, a different route may be used: slowing the growth of the longer leg (epiphysiodesis) can avoid lengthening altogether.
The figures below are approximate ranges for one leg, not hospital quotes. They depend on the method, the size of the gain, the hospital stay and the number of follow-up visits. Each hospital confirms its own price in writing.
| Country | Approximate cost range |
|---|---|
| Turkey | €9,000 – €30,000 |
| United Kingdom | €25,000 – €60,000 |
| United States | €45,000 – €140,000 |
| Germany | €25,000 – €70,000 |
What changes the price: a motorised nail costs much more than a frame because of the implant itself; a second operation to remove hardware, X-rays during lengthening, physiotherapy, and the number of nights in hospital also add up. A package normally includes the pre-operative tests, the operation and anaesthetist, hospital nights, the implant, early follow-up and airport transfers; ask what is not included, such as physiotherapy sessions and the later removal operation.
Recovery is long, because the bone grows slowly. In the first days you are in hospital, begin walking with crutches or a frame and learn the lengthening routine. During the distraction phase, usually one to three months, you attend physiotherapy and X-ray checks, and most patients cannot work in a physically demanding job. During consolidation, often several months, the load on the leg is increased step by step as the surgeon allows. Full return to sport and heavy work may take six months to a year. Left-leg lengthening has one practical detail: the left leg works the clutch in a manual car, but not the pedals in an automatic, so people can sometimes return to an automatic car earlier than after right-leg surgery, when the surgeon and the insurer agree that it is safe.
Many international patients stay in Turkey for the operation and the first two to three weeks, return home to continue the daily lengthening under a local physiotherapist, and have X-ray reports sent to the Turkish team. Ask how often you must travel back.
Photographs and X-rays show the equal leg length, the straightened pelvis and often a smoother gait. They do not show the months in a frame or on crutches, the scars, or the effort of physiotherapy. A realistic result is a leg of about the planned length, a much reduced limp and a gait that may keep improving for a year. Some patients keep a small leftover difference or mild stiffness, and a few need a second procedure. Ask the surgeon for X-rays of patients with a similar bone problem and for the average final gain, not only the most favourable case.
Good candidates are people with a proven length difference that causes problems, a healthy general condition, good motivation for months of physiotherapy and no active infection. You are less suited if you smoke and cannot stop, have uncontrolled diabetes or poor circulation in the leg, have bone infection that is not controlled, have severe joint contractures or cannot commit to the follow-up.
This is major surgery with a long recovery. Known problems include infection around the frame pins, joint stiffness or contracture (often the knee or ankle), nerve irritation, bone that heals too slowly or too quickly, a fracture at the lengthened site, blood clots, and implant problems. Professional bodies such as the American Academy of Orthopaedic Surgeons and the NHS advise a clear discussion of risks, a surgeon who performs the technique often, and a follow-up plan. Ask what happens if the bone does not heal and who treats you after you leave Turkey.
Choose a specialist in orthopaedics and traumatology who performs lengthening regularly, in a licensed hospital with an intensive-care unit, imaging and a physiotherapy department. Red flags include promises of exact centimetres, pressure to pay a deposit and no follow-up plan.

It is surgery to lengthen a short left femur or tibia. The bone is cut and lengthened slowly, about 1 mm a day, using a motorised nail or external frame while new bone forms in the gap.
Distraction osteogenesis is well established and most patients reach the planned length and a more even gait. Results vary with age, general health, the cause of the shortening and how well the bone heals.
Approximate ranges are €9,000 to €30,000 in Turkey, against about €25,000 to €60,000 in the UK. A motorised nail costs more than a frame; the hospital confirms its price in a written quote.
A single lengthening in one bone is often planned at about 3 to 8 cm. Larger differences may be divided between femur and tibia or staged, and the amount depends on the bone, muscles and joints.
Lengthening takes one to three months, and the bone then hardens over several months. Full return to heavy work or sport often takes six months to a year, with physiotherapy throughout.
An automatic car may be possible earlier than after right-leg surgery, because the left leg does not use the pedals. Ask your surgeon and insurer, and do not drive while taking strong painkillers.
Pain is expected, mainly in the first weeks and around lengthening sessions, and is managed with medication and physiotherapy. Muscle tightness and pin-site soreness can continue during the lengthening phase.
Neither is right for everyone. A nail avoids external pins but limits the amount and bone type, while a frame handles larger or angled corrections. The surgeon should explain the reason for their choice.
Risks include pin-site infection, joint stiffness, nerve irritation, slow or premature bone healing, fracture, blood clots and implant problems. Choose a surgeon who does this often and agree a follow-up plan.
Plan at least one to two weeks for the operation and the start of lengthening, and often longer. You then continue physiotherapy and X-ray checks at home, with return trips if the surgeon requires them.
