Objectives. The purpose of this study was to compare the results and complications of tibial lengthening over an intramedullary nail with treatment using the traditional Ilizarov method. Methods. In this matched case study, 16 adult patients underwent 19 tibial lengthening over nails (LON) procedures. For the matched case group, 17 patients who underwent 19 Ilizarov tibial lengthenings were retrospectively matched to the LON group. Results. The mean external fixation time for the LON group was 2.6 months and for the matched case group was 7.6 months. The mean lengthening amounts for the LON and the matched case groups were 5.2 cm and 4.9 cm, respectively. The radiographic consolidation time in the LON group was 6.6 months and in the matched case group 7.6 months. Using a clinical and radiographic outcome score that was designed for this study, the outcome was determined to be excellent in 17 and good in two patients for the LON group. The outcome was excellent in 14 and good in five patients in the matched case group. The LON group had increased blood loss and increased cost. The LON group had four deep infections; the matched case group did not have any deep infections. Conclusions. The outcomes in the LON group were comparable with the outcomes in the matched case group. The LON group had a shorter external fixation time but experienced increased blood loss, increased cost, and four cases of deep infection. The advantage of reducing external fixation treatment time may outweigh these disadvantages in patients who have a healthy soft-tissue envelope. Cite this article: J. E. Herzenberg.

The goal of this paper is to compare the results and complication namely infection rates, of the techniques of Standard Ilizarov lengthening, lengthening over nail (LON) and lengthening then nailing (LTN) utilizing a standard nail (STD) and a special nail with a core of cement releasing antibiotics (SAFE). In a first study done between 1993 and 2008, we have compared 25 patients treated with lengthening with a Ilizarov frame (LIF) with 26 patients where a standard nail was used to do a lengthening over nail technique (LON). From 2009 and 2012 we have utilized the SAFE nail in 17 patients to perform lengthening over nail (SAFE-LON) and lengthening then nailing (SAFE-LTN) techniques. 7 patients had a pseudarthrosis, 5 a malconsolidation with shortening and or axial deviation and 5 a bone loss after infection of total knee replacements. We used a lengthening over nail in 4 cases, a lengthening and axial correction then nailing in three, acute compression and proximal lengthening then nailing in five patients and knee arthrodesis and femoral or tibial lengthening then nailing in another 5 cases. We have used a Ilizarov frame in all cases. We found that with LON technique, the external fixation time was 3 times lower, promoting the recovery of full range of knee mobility in half the time, comparatively with LIF technique, with statistically very significant differences. We found a rate of 30% of intercurrences on the LON group and 24% in the Ilizarov, difference that was not statistically significant. 3 patients got bone infection after LON technique, a rate of 11.5%. Late consolidation and fracture of regenerate appeared only in the Ilizarov technique group, whereas in the LON technique we had 3 cases of premature consolidation of the regenerate. In the SAFE-LON and SAFE-LTN techniques utilizing the SAFE nail with antibiotics, we found a decrease of the overall intercurrence rate from 30% to 12% and namely, bone infection was cured or didn't appeared after nailing with this new device in all cases. LON and LTN techniques are somehow more demanding, but much more comfortable for the patient, which need to carry the frame for less time, It permits an earlier return to activity, about half the time, it controls better delayed regenerate and its fracture does not increase complication rate and costs of treatment and prevents infection when converting from external to internal fixation

Aims. To systematically review the outcomes and complications of cosmetic stature lengthening. Methods. PubMed and Embase were searched on 10 November 2019 by three reviewers independently, and all relevant studies in English published up to that date were considered based on predetermined inclusion/exclusion criteria. The search was done using “cosmetic lengthening” and “stature lengthening” as key terms. The Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement was used to screen the articles. Results. A total of 11 studies including 795 patients were included. The techniques used in the majority of the patients were classic 3- or 4-ring Ilizarov fixator (267 patients; 33.6%) and lengthening over nail (LON) (253 patients; 31.8%), while implantable lengthening nail (ILN) was used in the smallest number of patients (63 patients; 7.9%). Mean end lengthening achieved was 6.7 cm (SD 0.6; 1.5 to 13.0), and the mean follow-up duration was 4.9 years (SD 2.1; 41 days to 7 years). Overall, the mean number of problems, obstacles, and complications per patient was 0.78 (SD 0.5), 0.94 (SD 1.0), and 0.15 (SD 0.2), respectively. The most common problem and obstacle was ankle equinus deformity, while the most common complications were deformation of the regenerate after end of treatment and subtalar joint stiffness/deformity. Conclusion. Cosmetic stature lengthening provides favourable height gain, patient satisfaction, and functional outcomes, with low rate of major complications. Clear indications, contraindications, and guidelines for cosmetic stature lengthening are needed. Cite this article: Bone Joint Res 2020;9(7):341–350
