The problem of segmental bone loss of the tibia after fractures is an urgent and not completely resolved problem. The use of distraction osteogenesis by bone transport according to Ilizarov is the leading method of treatment. Improving this technology is a generally accepted way of improving treatment outcomes.To propose improvements in the technology of distraction osteosynthesis with the use of ring fixators, taking into account the problematic issues of their use; analyze the results obtained.Tasks: to formulate the disadvantages and problematic issues of distraction osteogenesis in patients with segmental defects of the leg bones after fractures; to propose a solution to the existing disadvantages of the method; analyze the results.78 victims met the inclusion criteria. 36 patients were operated on according to the proposed method; they made up the core group; 42 – comparison group, treatment was carried out according to the generally accepted method. The time spent in the external fixation apparatus and the index of external fixation were used as criteria for evaluating the results; the final assessment was carried out according to the anatomical and functional scale Modified Functional Evaluation System by Karlstrom–Olerud.Our results (good and excellent 77.8 %; unsatisfactory in 2.8 % are comparable to those of most researchers. Anatomical and functional results in the main group with a high degree of probability (˃95 %) exceeded the results in the comparison group.Bearing in mind the severity of the defeat, we find this result encouraging. Given the insufficient number of observations, it is necessary to recommend the use of the proposed improvements in the use of RF in the treatment of nonunions of the shin bones after fractures and further study of their effectiveness.Thus, nonunion of the tibia requires complex treatment using osteosynthesis with ring fixators. Spoke-rod designs of the apparatus, gentle technique, optimal ways of guiding the pins, transition to final fixation using Softcast/Scotchcast systems, drug correction of regeneration disorders made it possible to avoid many complications of extrafocal fixation and obtain good results.

Objective: To document the presentation of tibial infected non-union and analyze the management outcome with Ilizarov technique in terms of bone results, functional outcome, bone transport time, external fixation time, external fixation index and any complications. Methods: This case series was conducted at the Departments of Orthopedic Surgery, National Institute of Rehabilitation Medicine (NIRM), Islamabad and Civil hospital, Quetta over a period of 3-years. Results: There were 56 patients with 53(94.64%) males and 3(5.35%) females. The age range was 16-50 years with a mean of 32.58±9.98years. According to ASAMI criteria, bone results were excellent in 37(66%), good in 10(17.85%), fair in 6(10.71%) and poor in 3(5.35%). The functional results were excellent in 37(66%), good in 9(16%), fair in 7(12.5%) and poor in 3(5.35%). The bone union rate was 98.21%. Conclusion: Ilizarov method beautifully addresses the formidable issue of infected non union of tibia with good outcome in terms of bone healing and infection eradication. The treatment period is relatively lengthy and hence patience on part of patient as well as the surgical team is imperative for achieving favourable outcomes.

Abstract Background Large post-traumatic tibial bone defects combined with soft tissue defects are a common orthopedic clinical problem associated with poor outcomes when treated using traditional surgical methods. The study was designed to investigate the safety and efficacy of trifocal bone transport (TFT) and soft-tissue transport with the Ilizarov technique for large posttraumatic tibial bone and soft tissue defects. Methods We retrospectively reviewed 31 patients with massive posttraumatic tibial bone and soft tissue defects from May 2009 to May 2016. All of the eligible patients were managed by TFT and soft-tissue transport. The median age was 33.4 years (range, 2-58 years). The mean defect of bone was 11.87cm ± 2.78cm (range, 8.2-18.2cm) after radical resection performed by TFT. The soft tissue defects ranged from 7cm x 8cm to 24cm x 12cm. The observed results included bone union time, wound close time and true complications. The Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system was used to assess bone and functional results and postoperative complications were evaluated by Paley classification. Results The mean duration of follow-up after frame removal was 32 months (range, 12-96 months). All cases achieved complete union in both the elongation sites and the docking sites, and eradication of infection. The mean bone transport time was 94.04 ± 23.33 days (range, 63.7-147 days). The mean external fixation time was 22.74 ± 6.82 months (range, 14-37 months), and the mean external fixation index (EFI) was 1.91 ± 0.3 months/cm (range, 1.2–2.5 months/cm). The bone results were excellent in 6 patients, good in 14 patients, fair in 8 patients and poor in 3 patients. The functional results were excellent in 8 patients, good in 15 patients, fair in 5 patients and poor in 3 patients. Conclusion: TFT, in conjunction with soft tissue transport technique, can give good results in most patients (in this article, good and excellent results were observed in 64% of patients). Soft tissue transport is a feasible method in providing good soft tissue coverage on the bone ends. Although it has no advantages over microvascular techniques, it might be an good alternative in the absence of an experienced flap surgeon. Nonetheless, high-quality controlled studies are needed to assess its long-term safety and efficacy.

Introduction. Flexible flatfoot (FFF) is one of the most common skeletal disorders in children. In symptomatic patients who do not respond to conservative measures, surgery may be an option. Subtalar arthroereisis consists of limiting excessive eversion of the subtalar joint through different types of implants. Materials and Methods. We carried out a retrospective study of 16 patients (32 feet) intervened for FFF with a subtalar device (arthroereisis), across the period of 2008-2015 with a minimum follow-up period of one year. Pre- and postoperative measures of the Moreau-Costa-Bartani angle, dorsoplantar (DP) and lateral (L) talocalcaneal angle, talonavicular coverage angle, and naviculocuboid overlap were used to evaluate correction of the deformity. Two expert surgeons from the Pediatric Orthopedics Unit took separate measurements of these angles for subsequent analysis purposes and to obtain the interobserver correlation coefficient for quantitative variables. Pre- and postoperative differences in the measurement of angles were ascertained using Student’s t-test for paired samples; and a functional evaluation of the patients intervened was carried out pre- and postoperatively by administering the parent version of the Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) during a clinical interview. All statistical analyses were performed using the SPSS v. 19.0 program (SPSS, Chicago, IL), with values being deemed statistically significant at p<0.05. Results. A breakdown of the study population showed 81.25% (13 patients) males and 18.75% (3 patients) females, with mean age of 9 years (7-11). The interobserver coefficient for quantitative variables displayed a very high degree of concordance (0.7-0.9), indicating that the validity of the measures was adequate. Pre- and postoperative analysis of differences in the measurement of angles was statistically significant (p<0.005). In terms of functional evaluation, the postoperative results were positive, with statistical significance for the “school and play”, “emotional”, and “footwear” domains of the OxAFQ-C scale and no differences in the “physical” domain. Conclusion. Subtalar arthroereisis is a valid option for the treatment of symptomatic pediatric flatfoot, with good postoperative functional and radiographic results.

Conclusion The TFT in concert with soft-tissue transport technique can be used successfully to manage large tibial bone and soft-tissue defects. Soft-tissue transport can offer a feasible method for the defects with good soft tissue coverage on the bone ends. However, imprecision in the series results precludes a definitive conclusion, and comparative study is needed to assess whether soft-tissue transport is more effective than flap transfer for such soft-tissue defect.

One of the most common long-term complication of chronic osteomyelitis of tibia is segmental bone loss. One of the methods to manage the segmental bone loss in osteomyelitis is bone transport technique, which is able to reconstruct a defect of more than 6 cm. This paper aims to systematically review and analyze the outcome of bifocal and trifocal bone distraction technique on the tibial bony defect. A comprehensive literature search was performed using PubMed, Google Scholar, and Cochrane library. The inclusion criteria were any studies about comparison between bifocal bone transports with trifocal bone transport in management of large tibial bone defect. The outcomes assessed includes external fixation index, duration of regenerate consolidation, lengthening speed, bone transport distance, and operating time. Two studies reported shorter external fixation index in total of 57 fractures in the trifocal group and 61 fractures in the bifocal group. The meta-analysis showed significant difference in external fixation index between the two groups (Figure 1; RR=-44.37; 95% CI 73.73-15.01; p<0.0001) with significant heterogeneity (Chi square=11.38, p=0.0007); I2: 91%. Although only two studies were compared, both studies had almost similar subjects, and shown that trifocal bone transport technique had faster external fixator index compared to the bifocal bone transport group in the setting of severe bone loss in tibial fracture.

Objective To evaluate the effectiveness of bone transport involving circular external fixation and locking plate application for the treatment of segmental tibial defects. Methods A retrospective review of 12 patients with segmental tibial defects who underwent bone transport with circular external fixation and locking plate application. We evaluated external fixation time, external fixation index, time to achieve union, and complications. Clinical results were assessed using the Association for the Study and Application of the Methods of Ilizarov (ASAMI) score. Generic health-related outcome was assessed using the 36-Item Short-Form Health Survey questionnaire (SF-36). Results The mean follow-up was 25.8 months, and the mean defect size was 6.7 cm. All of the patients achieved union at the distraction callus and docking site. The average external fixation time was 299.5 days. The mean external fixation index was 16.5 days/cm, and the mean healing index was 44.9 days/cm. The functional outcomes were excellent in eight cases and good in four. The average SF-36 score was 92. Conclusion Bone transport with external fixation and locking plate application may be a promising method for the treatment of segmental tibial defects.

Treatment of congenital pseudarthrosis of the tibia remains a major challenge in pediatric orthopedics. Ideal timing and preference of surgical procedures are discussed controversially. A variety of reconstructive treatment strategies have been described in literature, but so far none has proven its superiority. The aim of treatment is to obtain long-term bone union, to prevent refracture, and to correct angular deformities and leg length discrepancies. This study retrospectively evaluates the outcome of different reconstructive strategies. Sixty-nine patients were identified who presented to our outpatient department between 1997 and 2019. Twenty-six of these patients underwent reconstructive surgical treatment and were included in this study. The study cohort was divided into three groups. Excision of the pseudarthrosis was performed in all patients in Group A and B, and in two patients of Group C. Group A (six/26 patients) received subsequent bone transport through external fixation maintaining original length. In Group B (15/26 patients), patients underwent either previous, simultaneous, or subsequent extrafocal lengthening through external fixation to reconstitute length. In Group C (five/26 patients), internal fixation with intramedullary nails was applied. Radiological and clinical evaluation was performed to assess bone union and complication rates. Results varied considerably between the study groups. Overall, the primary bone fusion rate was 69.2%. There were four refractures, all occurring in Group B. The long-term bone union rate without refracture was 53.8%. The overall complication rate was 53.8% and 23.1% showed persistent pseudarthrosis. Two secondary amputations were performed due to failed bone fusion. In conclusion, excision of the pseudarthrosis and extrafocal lengthening achieves a satisfying bone union rate and limb reconstruction, while bone transport does not offer significant advantages but shows higher complication rates. Intramedullary stabilization should be applied to maintain bone union, but shows lower bone union rates when used as a stand-alone treatment regimen. Regardless of the primary bone fusion rates, the probability of long-term bone union remains unpredictable.
