Common Location

Septic non union has still been a challenge for orthopedic surgeons. Its resolution is complex and has hight morbility. It needs a multidisciplinary approach. Distal tibia is a common location due its poor vascularity and soft tissues. We present a patient with pseudoarthrosis of the tibia treated with resection and bone transport. Contact was achieved at the docking site at 5 months. Bone grafting and freshening of fracture ends was performed. At 12 months the frame was removed after complete consolidation. As the only complication, the patient suffered two episodes of cellulitis that were resolved with antibiotic therapy.

Abstract Background Retraction of transporting bone segment (TBS) may occur when the fixator of the TBS is removed prior to full consolidation of the distracted callus, which has adverse effect on the healing of the docking site. However, there are few reports on the retraction of TBS. The purpose of this study is to analyze the causes and risk factors of the retraction of TBS. Methods The clinical data of 37 cases with tibial bone defect treated by Ilizarov bone transport were analyzed retrospectively, in whom the TBS fixator was removed prior to full consolidation of the distracted callus and union of the docking site. Bivariate correlation was used to analyze relationship between the retraction distance of TBS and potential risk factors including age, gender, course, length of bone defect, number of operations, size of TBS, transport distance, timing and time interval of removal of TBS fixator. Risk factors with significant level were further identified using multivariate linear regression. Results Bivariate correlation showed that the timing of removal was negatively correlated with the retraction distance, and the time interval and transport distance were positively correlated with the retraction distance(p < 0.05), the age, gender, course, length of bone defect, size of TBS and number of operations were not correlated with the retraction distance(p > 0.05). Multivariate linear regression of the 3 risk factors showed that the timing of removal and time interval were the main risk factors affecting the retraction distance (p < 0.05), but the transport distance was not (p > 0.05). Conclusion The traction forces of TBS endured from the soft tissues and the unconsolidated distracted callus have elastic properties, which can make retraction of TBS. The timing of removal and time interval are the main risk factors of the retraction of TBS. In the case of early removal, another external fixation or quickly converted to internal fixation should be performed to avoid the adverse effect of more retraction.

Membrane Technique

Introduction The Masquelet induced membrane technique is effective in the management of acquired heterogeneous long bone defects and pseudarthrosis. The combination of the Masquelet technology and Ilizarov non-free bone grafting seems promising and reduces the risks of recurrence at long-term in patients with congenital pseudarthrosis. Purpose Presentation of new technological solutions that allow combining the advantages of the Ilizarov bone transport and Masquelet bone grafting in patients with acquired bone defects. Materials and methods Retrospective assessment of the results of bone reconstruction in 10 patients who were treated by a combination of Ilizarov and Masquelet bone grafting technologies to repair long bone defects after failures of previous treatment. Fragments of the biomembrane formed around the cement spacer temporarily replacing the tibial gap after resection bone defect or pseudarthrosis were examined in all patients. The studies were carried out using a Reichard sledge microtome, an AxioScope stereomicroscope and an AxioCam ICc 5 digital camera, a JSM- 840 scanning electron microscope and an INCA-200 Energy X-ray electron probe microanalyzer. Results and discussion The combined Masquelet technique and Ilizarov non-free bone plasty provide the conditions that are favorable for reparative processes of the transported fragments. After removal of the spacer, there is a tunnel formed in the interfragmental gap, the walls of which are made of the induced membrane. Bone transport is carried out without technical problems through the compromised tissues which are debrided at the time of distraction initiation, outside the scars. At the same time, there are low risks of inflammation around the transosseous elements; there is no danger of cutting and perforation of soft tissues by transported fragments. Conclusions Complete organotypic rearrangement of the distraction regenerate with the use of Ilizarov non-free bone plasty and the Masquelet technique excludes the possibility of deformities or fractures at the level of newly formed bone areas. Active distraction histogenesis ensures the closure of soft tissue defects without additional reconstructive plastic interventions. The revealed dependence of the induced membrane blood supply on the method of treatment previously used might be a criterion for predicting the treatment outcome in patients with acquired bone defects and pseudarthrosis.

Compression Plating

Nonunion after diaphyseal fracture of the femur or the tibia is a common but difficult complication for treatment. Currently, the main treatment modalities include nail dynamization, exchange nailing, and bone transport, but revision with compression plating in these nonunions was rarely reported. To evaluate the outcomes of compression plating in the treatment of femur and tibia shaft nonunions, we retrospectively reviewed 54 patients with diaphyseal nonunion of the tibia or the femur treated with locking compression plate (LCP) by compression technique. There were 46 aseptic and 8 septic nonunions in the case series. Patient’s history, fracture characteristics, previous interventions, and types of nonunion were recorded. The possible reason which might lead to nonunion was also analyzed for each case. Patients with aseptic nonunions were revised by hardware removal and compression plating with or without bone grafting. For septic nonunions, a two-stage surgery strategy was used. Compression plating with iliac crest bone grafting (ICBG) or free vascularized fibular grafting (FVFG) was used as the final treatment for septic nonunions. The compression technique and bone grafting method were individualized in each case according to the patient’s history and architecture of the nonunion. Each patient finished at least a two-year follow-up, and all cases achieved healing uneventfully. Our study showed that compression plating with LCP was an effective method to treat diaphyseal nonunions of the tibia and the femur. It is compatible with different bone grafting methods for both infected and noninfected nonunions and is a good alternative to the current treatment methods for these nonunions.

Abstract Background: The treatment for infected tibial bone defects can be a great challenge for the orthopaedic surgeon. This meta-analysis was conducted to compare the efficacy and safety between bone transport (BT) and the acute shortening technique (AST) in the treatment of infected tibial bone defects.Methods: A literature survey was conducted by searching the PubMed, Web of Science, Cochrane Library, and Embase databases together with the China National Knowledge Infrastructure (CNKI) and the Wanfang database for articles published up to 9 August 2019. The Newcastle-Ottawa scale (NOS) was adapted to evaluate the bias and risks in each eligible study. The data of the external fixation index (EFI), bone grafting, bone and functional results, complications, bone union time and characteristics of participants were extracted. RevMan v.5.3 was used to perform relevant statistical analyses. Relative risk (RR) was used for the binary variables and standard mean difference (SMD) for continuous variables. Each variable included its 95% confidence interval (CI).Results: Five studies, including a total of 199 patients, were included in the meta-analysis. Statistical significance was observed in the EFI (SMD = 0.63, 95% CI: 0.25, 1.01, P = 0.001) and bone grafting (RR = 0.26, 95%CI: 0.15, 0.46, P <0.00001); however, no significance was observed in bone union time (SMD = –0.02, 95% CI: –0.39, 0.35, P = 0.92), bone results (RR = 0.97, 95% CI: 0.91, 1.04, P = 0.41), functional results (RR = 0.96, 95% CI: 0.86, 1.08, P = 0.50) and complications (RR = 0.76, 95% CI: 0.41, 1.39, P = 0.37).Conclusions: AST is preferred from the aspect of minimising the treatment period, whereas BT is superior to AST for reducing bone grafting. Due to the limited number of trials, the meaning of this conclusion should be taken with caution for infected tibial bone defects.Trial registration: PROSPERO CRD42019133659
