“…Once the desired length has been achieved, the IM nail is stabilized with distal locking screws and the frame is removed. The locked nail provides rotational and axial stability while protecting the regenerate bone [6]. With earlier removal of the external fixator, the complication rates related to the pins, including pin tract infections and joint stiffness, are substantially diminished [13].…”

Background Lengthening over a nail and internal lengthening nails have been developed to minimize or eliminate patients' time wearing a frame during femur lengthening. However it is unclear whether either of these two approaches results in faster times to union or fewer complications over the other. Questions/purposes We asked which technique better achieved: (1) the lengthening goals, (2) the distraction rate control, (3) quality of the regenerate bone, (4) fewer complications, and (5) SF-36 and AAOS LLM scores also were compiled. The minimum followups for the ISKD and the lengthening over nail cohorts were 62 months (average, 76 months; range, 62-93 months) and 13 months (average, 27 months; range, 13-38 months), respectively. Results We observed no difference in achieving the lengthening goals between the two procedures. Distraction was not well controlled in the ISKD group; the distraction rates were 1.7 mm per day for the fast group (distraction rate greater than 1 mm/day) and 0.84 mm per day for the slow group (less than 1 mm/day). The lengthening over nail group had an average distraction rate of 0.88 mm per day. One of 20 of the patients who had lengthening over a nail had complications requiring additional unanticipated surgeries whereas six of 12 patients who had femoral lengthening in the ISKD group had such complications. Conclusions Based on our observations, we believe the lengthening over nail technique for femoral lengthening is associated with fewer complications than the ISKD. Level of Evidence Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

“…With a consolidation index of 35.2 days/cm, the Albizzia 1 nail appears faster [14]. The consolidation index in the ISKD 1 ranged from 21 to 29 days/cm [21,27]. In our group with the FITBONE 1 TAA, the consolidation index was 26 days/cm.…”

“…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].…”

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.

“…Iobst and Dahl (2007) reported promising results with this technique with no infections associated with the method. Lengthening nails with no use of an external distraction device show promising results in case reports, but is associated with hardware failures and unsatisfactory achievements of longer lengthenings (Baumgart 2008, Hankemeier et al 2004, Paley 2007.…”
