Doctor Ginebreda is one of the surgeons authorised to perform limb lengthening with the Fitbone method.

The intramedullary nail corrects deformities in people with a shorter leg.

The system consists of a self-expanding device capable of gradually increasing the length of the treated bones.

It can be implanted in the tibia and femur, in one leg, or both.

This leg lengthening surgery has many advantages over traditional external fixators:
– The patient can walk from the first day.
– After the operation, the treatment is completely painless.
– Low risk of infection.
– Hospitalisation and treatment time is reduced.
– Patients can resume their routine activities more quickly.

What is Limb Lengthening Surgery with the Fitbone Method?

Fitbone consists of a self-expanding device (an intramedullary nail) manufactured by the German company Wittenstein. The nail is inserted into the bone (tibia and / or femur).

After programming the intramedullary nail, it is able to gradually lengthen the bone, improving the patients’ quality of life.

The skin, tissues and nerves grow in proportion to the length of the bone.

After the nail placement procedure, the patient is hospitalised for 5 days.

The mechanism is programmed to regulate lengthening, which should be very slow but constant. Legs can be lengthened thanks to the great regenerative capacity of bone tissue.

Thanks to this technology, 1 millimeter per day is achieved. Therefore, for 40mm, about 40 days are needed.

With the conventional system of external fixators, it would take 5 more months to be able to lead a normal life.

How Many Centimetres can you Grow?

The intramedullary nail achieves a lengthening of up to 60 mm in the tibia and up to 80 mm in the femur.

In cases where lengthening both legs is recommended, a lengthening of 140mm per leg can be achieved.

It is important that the patient accompanies the treatment with a program of physical therapy and muscle stretching.

After bone healing is complete (approximately one and a half years after implantation), the intramedullary nail is removed.

Limb Lengthening Surgery can Have Negative Effects at Long Term?

The surgery has no negative effects at long term. The lengthened bone is a healing tissue at the beginning, but after full consolidation is achieved it has all properties as physiological bone.

In fact, the lengthened bone has a harder consistency than the physiological bone, so it is no weaker.

The aim of this treatment is to allow the patient to return to his previous physical state and to recover his sports activities.

Which Patients can Undergo the Surgery?

First of all, we find patients with congenital dysmetria, traumatic dysmetria. Other patients have femorotibial disproportions (asymmetries, asymmetries of the lower limbs).

When dysmetria is mild, elevator shoes or heels are usually used. However, when the dysmetry is greater than 3 cm, limb lengthening is recommended.

Leg lengthening surgery with the Fitbone method is also used in patients with dwarfism, mainly patients with achondroplasia.

There are also patients who want to stretch their legs for cosmetic reasons. In these cases, there is always a medical and psychological assessment. It is very important to achieve a proportionate result.

What are the Advantages of the Fitbone Technique?

Unlike the traditional external fixation method, the Fitbone technique allows the patient to perform low impact activities. During the treatment he can carry out activities such as going for a walk without any problem.

It is a painless treatment. The patient does not experience pain during the treatment.

In addition, compared to the traditional technique, the Fitbone technique decreases the risk of infection. Scar formation and hospital stay are also reduced. Patients can resume their routine activity in a short time.

It is a more comfortable method for the patient because he do not use traditional external fixators. The intramedullary nail is a highly reliable and technologically tested mechanism.

Is the Fitbone Method Recommended for Children?

Limb lengthening with the Fitbone Method is not recommended for children under 10 years old. For cases between 11 and 14 years old, doctors should study the specific characteristics of the patient (difference in length, remaining growth, deformity).

From the age of 16, once the growth cartilages have been closed, the patient can consider a leg lengthening surgery.

How Many Steps does the Limb Lengthening Surgery Take?

In patients who need to lengthen both legs, Doctor Ginebreda recommends performing limb lengthening at the same time.

This avoids having to schedule two surgeries and shortens the recovery time.

Implants should be removed 2 years after the end of limb lengthening treatment.

How Much is Limb Lengthening Surgery with the Fitbone Method?

Limb lengthening cost with the Fitbone method depends on several factors.
