Surgeons explain the benefits of the FITBONE® method
Around the world, WITTENSTEIN intens works exclusively with selected Centers of Excellence. Here, patients receive treatment with FITBONE® from experienced, trained surgeons. Learn the benefits of FITBONE® over other treatment methods directly from international specialists.
The FITBONE® System consists of the following components
The FITBONE® System is used for correcting leg length discrepancies. With appropriate preoperative planning, it is possible to make axial and torsional corrections as part of limb lengthening.
The FITBONE® intramedullary lengthening nail can
be used to achieve an extension of 60 mm in the
lower leg (tibia) and 80 mm in the upper leg (femur).
The energy required for the distraction process
is transferred to the receiver implanted beneath
the skin by applying an external controller set.
After the bone has been severed, it is stabilized
by means of the intramedullary lengthening nail.
After a period of rest, the patient can resume treatment
independently at home.
FITBONE® is surgically implanted into the bone.
There is no contact between the implanted intramedullary
lengthening nail and the outer surface of the patient's body.
A leader in quality, reliability and experience
Each lengthening action takes around 90 seconds. The patient performs it independently at home about three times a day. The distraction rate is determined by the surgeon and is one millimeter per day, so 80 millimeters of lengthening takes approximately 80 days. After the distraction phase comes the consolidation phase, during which the reformed bone hardens.
The operated limb can bear partial weight relatively early on. Near the end of the distraction phase, this process can be gradually increased to full weight-bearing. This allows patients to return to their personal and professional routines earlier.
After complete consolidation of the bone, i.e. after one to one and a half years after implantation, the FITBONE® intramedullary lengthening nail and the receiver must be explanted.
An expert's opinion
"There are many possible benefits: less scarring, improved esthetics, better body image and psychological well-being, no irritation from pins or wires, less pain, no unusual infections, prevention of secondary axial deviation, less stiffness in the joints, higher level of activity during the consolidation process, faster rehabilitation, reduced risk of neurovascular impairment from insertion of wires or screws, and improved ability to work during and after treatment."

The FITBONE® for special needs
Custom-made devices are manufactured according to the specific needs of our patient. One example is a lengthening nail that uses segment transport to produce new bone following a bone resection (as a result of an accident or a tumor). Healthy bone tissue is transferred over the defective area and forms new bone.
Our 'Centers of Excellence' concept guarantees the highest quality and safety
Only qualified orthopedic clinics are approved as Centers of Excellence for FITBONE® treatment. Preconditions include demonstrated experience and the willingness to play a leading role in limb lengthening and deformity correction. Training involves an intensive training program and learning the Reverse Planning Method developed by Prof. Rainer Baumgart. We also offer participation in FITBONE® User Meetings and the sharing of experiences in our Center of Excellence network.
