“…Callus distraction by intramedullary lengthening has become an alternative treatment method for limb lengthening during the last 5 years [4,6,9,14,19,21,27,37]. Few data have been published concerning the FITBONE 1 TAA for intramedullary leg lengthening [4,6,37].…”

“…Few data have been published concerning the FITBONE 1 TAA for intramedullary leg lengthening [4,6,37]. The concept that led to the development of techniques using intramedullary nails for callus distraction was to achieve leg lengthening with faster rehabilitation and a lower rate of complications [3,9,19].…”

“…These measurements were made under conditions based on the preoperative standard protocol for retrograde corrective planning described by Baumgart et al [4,6]. Different from conventional trauma nails, the femoral FITBONE 1 TAA is straight, which must be considered in preoperative planning.…”

“…For lengthening, we used the FITBONE 1 TAA, a fully implantable, motorized intramedullary nail that is available in various sizes and different designs for the femur and the tibia [6,37]. The femoral nail is a straight stainless steel nail with a maximum distraction length of 40 to 80 mm.…”

Leg lengthening by external fixation is associated with various difficulties. We evaluated eight adolescent patients who underwent leg lengthening with a motorized intramedullary lengthening device. We asked whether this method could reduce the time of hospitalization and rehabilitation and whether the incidence of complications commonly associated with external fixators could be reduced. We compared our preliminary results with those from other reports, with a focus on leg length achieved, time of rehabilitation, and rate of complications. The average leg-length discrepancy was 3.8 cm (range, 3-5 cm). The average lengthening distance was 3.8 cm (range, 2.9-4.7 cm). In six patients, leg lengthening was combined with successful correction of the mechanical axis alignment. The consolidation index averaged 26 days/cm (range, 19-41 days/cm). The average hospital stay was 9.6 days. No bone or soft tissue infections were observed. In comparison to other studies (1.0-2.8 complications/ patient), our results suggest that the difficulties commonly associated with external fixators can be reduced with this method. It also allows good angular correction in patients with mechanical axis deviation. These features combined with a short time of hospitalization and rehabilitation make it a promising procedure for limb lengthening.
