“…As an entirely modular system, good clinical outcomes rely on an appropriate understanding of how best to apply the frame components, tailored to each patient, to produce a construct which will sufficiently control the mechanical environment at the fracture or osteotomy site to allow bone healing [27,29]. Developments on the original Ilizarov method of fine-wire fixation have introduced elements, such as threaded half-pins, which allow more versatility in frame application and with reduced muscle transfixion.…”

Background Fine-wire circular frame (Ilizarov) fixators are hypothesized to generate favorable biomechanical conditions for fracture healing, allowing axial micromotion while limiting interfragmentary shear. Use of half-pins increases fixation options and may improve patient comfort by reducing muscle irritation, but they are thought to induce interfragmentary shear, converting beam-to-cantilever loading. Little evidence exists regarding the magnitude and type of strain in such constructs during weightbearing. Questions/purposes This biomechanical study was designed to investigate the levels of interfragmentary strain occurring during physiologic loading of an Ilizarov frame and the effect on this of substituting half-pins for finewires. Methods The ''control'' construct was comprised of a four-ring all fine-wire construct with plain wires at 90°-crossing angles in an entirely unstable acrylic pipe synthetic fracture model. Various configurations, substituting half-pins for wires, were tested under levels of axial compression, cantilever bending, and rotational torque simulating loading during gait. In total three frames were tested for each of five constructs, from all fine-wire to all half-pin. Results Substitution of half-pins for wires was associated with increased overall construct rigidity and reduced planar interfragmentary motion, most markedly between all-wire and all-pin frames (axial: 5.9 mm ± 0.7 vs 4.2 mm ± 0.1, mean difference, 1.7 mm, 95% CI, 0.8-2.6 mm, p \ 0.001; torsional: 1.4% ± 0.1 vs 1.1% ± 0.0 rotational shear, mean difference, 0.3%, 95% CI, 0.1%-0.5%, p = 0.011; bending: 7.5°± 0.1 vs 3.4°± 0.1, mean difference, À4.1°, 95% CI, À4.4°to À3.8°, p \ 0.001). Although greater transverse shear strain was observed during axial loading (0.4% ± 0.2 vs 1.9% ± 0.1, mean difference, 1.4%, 95% CI, 1.0%-1.9%, p \ 0.001), this increase is unlikely to be of clinical relevance given the current body of evidence showing bone healing under shear strains of up to 25%. The greatest transverse shear was observed under bending loads in all fine-wire frames, approaching 30% (29% ± 1.9). This was reduced to 8% (±0.2) by incorporation of sagittal plane half-pins and 7% (±0.2) in all half-pin frames (mean difference, À13.2% and À14.0%, 95% CI, À16.6% to 9.7% and À17.5% to À10.

Background: Circular external fixation including Ilizarov method is a well-established technique often practiced in orthopedic surgery. The goal of this procedures is to lengthen extremity bones, reconstruct severely injured or fractured bone trauma, correct congenital bone deformities, treat infected bones and to treat pseudarthrosis. The importance of this study is that it will highlight the most common complications for this procedure in order to reverse them and have a better clinical outcome. The aim of this study is to assess the indications and postoperative complication rates following tibial circular external by Illizarov's method. Methods: We performed a consecutive case series, chart review study of 33 patients who were treated with the Ilizarov method, between 2010 and 2016. All patients who underwent tibial circular external fixators using Ilizarov method were selected for this study. There were 25 males and 8 females, mean age was 31.06 (range 14 -71). All data collected was coded in Excel sheet. SPSS package version 20 was used for data analysis. Results: The total number of subjects involved in this study was 33 subjects (Male: 25[75%]-Female: 8[25%]). The average age of the subjects was 31.06 (range 14 -71) with a standard deviation of +/-13.8. Overall, 63.6% of patients reported post-op complications. Whereas 36.3% of patients were free of complications. The main complication was pain which was reported in 15% of the subjects. Conclusion: There was a minimal complication rate associated with this technique in our institution compared to published studies. Several medical conditions were the indication for this procedure, primarily motor vehicle accidents deformities.
