Abstract
PURPOSE Refracture is one of the main complications of bone transport, which brings additional physical and mental burden to surgeries and patients. We aimed to raise a new classification system of refracture-related bone transport based on the Simpson classification and to present our experience on treatment. METHODS This retrospective analysis included 19 patients with refracture-related bone transport (average age of 37.7 years; 18 men). We developed a modified Simpson classification system to assist decision-making (conservative versus surgical). The ASAMI criteria were used to assess the outcomes at last follow-up. RESULTS The mean follow-up was 12.3 ± 3.2 months. Complete union was achieved in all patients, with no reinfection. Based on the modified Simpson classification, refracture was Ia type (within regeneration area) in three cases, Ib (collapsed fracture at the regeneration area) in one case, Ic (stress fracture) in three cases, II (at the junction between the regenerate and original bone) in one case, III (at the docking site) in nine cases, and V (at distant site) in two cases. Refracture was managed conservatively in six cases and surgically in 13 cases. Average time to bone union was 2.8 ± 1.2 months in the conservative group versus 4.4 ± 1.4 months in the surgery group. Assessment at the final follow-up using the ASAMI criteria revealed excellent bone result in all patients, excellent functional results in six patients (31.6%), and good functional results in 13 patients. CONCLUSIONS The modified Simpson classification could include refracture at the docking site and stress fracture in the regeneration zone and provide some guidance in determining the appropriate treatment strategy.

Abstract
The aim of this narrative review is to describe the various surgical management strategies employed in fracture-related infection (FRI), to explore how they are selected and discuss the rationale for early surgical intervention. Surgical treatment options in patients with FRI include debridement, antibiotics and implant retention (DAIR), revision (exchange) or removal. In selecting a treatment strategy, a variety of factors need to be considered, including the condition of the bone, soft tissues, host and causative microorganism. Irrespective of the selected treatment strategy, prompt surgical intervention should be considered in order to confirm the diagnosis of an FRI, to identify the causative organism, remove necrotic or non-viable tissue that can serve as a nidus for ongoing infection, ensure a healthy soft tissue envelope and to prevent the vicious cycle of infection associated with skeletal and/or implant instability. Ultimately, the objective is to prevent the establishment of a persistent infection. Urgent surgery may be indicated in case of active, progressive disease with systemic deterioration, local progression of infection, deterioration of soft tissues, or progressive fracture instability. In case of static disease, the patient should be monitored closely and surgery can be performed on an elective basis, allowing adequate time for optimisation of the host through risk factor modification, optimisation of the soft tissues and careful planning of the surgery.

Abstract
Background The Cierny and Mader classification assists with decision-making by stratifying host status and the pathoanatomy of the disease. However, the anatomical type IV represents a heterogenous group with regard to treatment requirements and outcomes. We propose that modification of the Cierny and Mader anatomical classification with an additional type V classifier (diffuse corticomedullary involvement with an associated critical bone defect) will allow more accurate stratification of patients and tailoring of treatment strategies. Methods A retrospective review of 83 patients undergoing treatment for Cierny and Mader anatomical type IV osteomyelitis of the appendicular skeleton at a single centre was performed. Results Risk factors for the presence of a critical bone defect were female patients [OR 3.1 (95% CI, 1.08-8.92)] and requirement for soft tissue reconstruction [OR 3.35 (95% CI, 1.35-8.31)]; osteomyelitis of the femur was negatively associated with the presence of a critical bone defect [OR 0.13 (95% CI, 0.03-0.66)]. There was no statistically significant risk of adverse outcomes (failure to eradicate infection or achieve bone union) associated with the presence of a critical-sized bone defect. The median time to the bone union was ten months (95% CI, 7.9-12.1 months). There was a statistically significant difference in the median time to bone union between cases with a critical bone defect [12.0 months (95% CI, 10.2-13.7 months)] and those without [6.0 months (95% CI, 4.8-7.1 months)]. Conclusion This study provided evidence to support the introduction of a new subgroup of the Cierny and Mader anatomical classification (Type V). Using a standardised approach to management, comparable early outcomes can be achieved in patients with Cierny and Mader anatomical type V osteomyelitis. However, to achieve a successful outcome, there is a requirement for additional bone and soft tissue reconstruction procedures with an associated increase in treatment time.

Abstract
OBJECTIVES To compare bone transport through induced membrane (BTM) and conventional bone transport (BT) regarding docking site union and infection recurrence in the management of infected long-bone defects. DESIGN Prospective, randomized, controlled study. SETTING Tertiary-level center. PARTICIPANTS Thirty patients with infected nonunited long-bone fractures of lower limbs were included. INTERVENTION Fifteen patients were treated by BTM in group A, and 15 patients were treated by BT in group B. OUTCOME MEASUREMENTS The outcome measures were external fixation time, external fixation index, and docking time. Bone and functional outcomes were evaluated by the Association for the Study and Application of the Method of Ilizarov scoring system. Postoperative complications were evaluated according to the Paley classification. RESULTS The mean docking time was significantly lower in the BTM group than in the BT group (3.6 ± 0.82 months vs. 4.8 ± 0.86 months, respectively; P value 0.001). Docking site nonunion and infection recurrence were significantly lower in the BTM group than in the BT group (0% vs. 40%; P value 0.02 and 0% vs. 33.3%; P value 0.04, respectively), with no significant difference in the external fixation index ( P value 0.08). CONCLUSIONS This is the first prospective, randomized, controlled study comparing BTM and BT techniques, showing that BTM had significantly faster docking site union, lower incidence of postoperative complications including docking site nonunion and infection recurrence rates, and lower number of additional procedures needed at the expense of 2-staged operation in comparison with BT.

Abstract
Bone graft in trauma surgery is commonly used in managing bone defects, non-union, fracture related infections, arthrodesis or to provide structural support in fractures. A variety of bone grafts are made available to the treating physician, which includes autograft, allograft and bone graft substitutes. The future of bone grafting in trauma surgery is exciting with the incorporation of technological advancement such as gene therapy, 3D-printing and tissue engineering. Regardless, there are still limitations to what we understand regarding current bone grafting techniques with conflicting literature on their clinical utility and indication. The aim of this review article therefore is to take a step back and critically evaluate the current concepts of bone grafting in trauma surgery, with special emphasis made on reviewing the types of bone graft, biology of bone graft incorporation and indication for its use in various clinical scenarios.

Abstract
PURPOSE Dead space management is critically important during the treatment of chronic osteomyelitis. Many dead space management strategies are available, each with their respective advantages and shortcomings. This study aims to present the outcomes and complications of dead space management strategies employed in the treatment of chronic osteomyelitis at a single tertiary level musculoskeletal unit. METHODS A retrospective review of dead space management strategies employed at a tertiary-level musculoskeletal infection unit was conducted. Patients of any age treated for chronic osteomyelitis of the appendicular skeleton with a minimum follow-up of 6 months were included in the study. Data were collected regarding patient demographics, aetiology and site of infection, dead space management strategy employed, follow-up period and outcome in terms of resolution of infection. RESULTS A final cohort of 132 patients underwent surgical treatment with a dedicated dead space management strategy for chronic osteomyelitis of the appendicular skeleton. Eleven patients (8%) experienced a recurrence of infection. Seven patients (63%) with recurrence were type B hosts, while four patients (37%) were type A hosts. CONCLUSION Dead space management is an integral part of treating chronic osteomyelitis; however, no guidelines currently exist regarding the most appropriate strategy. Favourable results are achievable in low to middle-income countries, and it is evident that no dead space management strategy is superior to another. The pursuit for the ideal void filler is ongoing.

Abstract
PURPOSE Masquelet and Ilizarov techniques have their advantages and shortcomings in the reconstruction of bone defects. The aim of this study was to evaluate the effectiveness of the combination of both techniques for the management of infected tibial nonunion to combine the advantages of both techniques with avoidance of shortcomings of both of them. PATIENTS AND METHODS A prospective single-centre study was performed during the period from 2012 to 2019. Patients with the infected nonunion of the tibia with bone defect were included. Patients with pathological fractures or non-infected bone loss were excluded. Management protocol for all patients consisted of two stages. The first stage was Masquelet induced membrane technique and the second stage was Ilizarov bone transport. The results were assessed based on both objective (clinical and radiographic evaluation) and subjective criteria (limb function and patient satisfaction). RESULTS Thirty-two patients were included in this study. The mean size of the defect was 6 cm. Ilizarov bone transport was done through the induced membrane chamber in all cases with an average follow-up of 28 months. Successful reconstruction without recurrence of infection was achieved in 30 cases (94%). No other bone or soft tissue procedure was needed with satisfactory functional outcome in 27 out of 30 cases (90%). Three cases had unsatisfactory results due to leg length discrepancy, joint stiffness, and persistent pain. CONCLUSIONS Masquelet-Ilizarov technique can be used for the management of infected nonunion tibia with high satisfactory results without the need for complex soft tissue procedures.

Matched comparative study of trifocal bone transport versus induced membrane followed by trifocal bone transport in the treatment of segmental tibial defects caused by posttraumatic osteomyelitis. BMC Musculoskelet Disord 2022; 23:572. [PMID: 35701789 PMCID: PMC9195234 DOI: 10.1186/s12891-022-05501-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 05/30/2022] [Indexed: 11/15/2022] Open
Abstract
Objectives To compare the efficacy and clinical outcomes of trifocal bone transport (TBT) versus induced membrane followed by trifocal bone transport (IM + TBT) in the treatment of tibial defects > 6 cm caused by posttraumatic osteomyelitis. Methods A total of 69 eligible patients with tibial defects > 6 cm who were treated between January 2010 and January 2018 were retrospectively reviewed. Overall, 18 patients treated by IM + TBT and 18 treated by TBT were matched by propensity score analysis. The mean tibial defect after radical debridement was 6.97 ± 0.76 cm (range, 6.0 to 8.9 cm). The measurements, including demographic data, external fixation index (EFI), external fixation time (EFT), duration of docking union, bone and functional outcomes evaluated by the Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system, and postoperative complications evaluated by Paley classification during follow-up were recorded. Results Age, gender, injury mechanism, affected side, defect size, previous operation time, and follow-up time were not significantly different between the two groups (P > 0.05). The mean EFT was 293.8 ± 12.1 days in the TBT group vs. 287.5 ± 15.3 days in the IM + TBT group. The mean EFI was 36.02 ± 2.76 days/cm vs. 34.69 ± 2.83 days/cm, respectively. The mean duration of docking union was 210.7 ± 33.6 days vs. 179.7 ± 22.9 days, respectively. There was no significant difference in postoperative bone and functional results between the two groups. Delayed union or nonunion and soft tissue incarceration were significantly reduced in the IM + TBT group compared to those in the TBT group. Conclusion Both TBT and IM + TBT achieved satisfactory postoperative bone and functional outcomes in patients with segmental tibial defects > 6 cm following posttraumatic osteomyelitis, while IM + TBT had a significantly lower incidence of postoperative complication in delayed union or nonunion and soft tissue incarceration, as well as faster docking union.

Union, complication, reintervention and failure rates of surgical techniques for large diaphyseal defects: a systematic review and meta-analysis. Sci Rep 2022; 12:9098. [PMID: 35650218 PMCID: PMC9160061 DOI: 10.1038/s41598-022-12140-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 04/25/2022] [Indexed: 12/20/2022] Open
Abstract
To understand the potential and limitations of the different available surgical techniques used to treat large, long-bone diaphyseal defects by focusing on union, complication, re-intervention, and failure rates, summarizing the pros and cons of each technique. A literature search was performed on PubMed, Web of Science, and Cochrane databases up to March 16th, 2022; Inclusion criteria were clinical studies written in English, of any level of evidence, with more than five patients, describing the treatment of diaphyseal bone defects. The primary outcome was the analysis of results in terms of primary union, complication, reintervention, and failure rate of the four major groups of techniques: bone allograft and autograft, bone transport, vascularized and non-vascularized fibular graft, and endoprosthesis. The statistical analysis was carried out according to Neyeloff et al., and the Mantel–Haenszel method was used to provide pooled rates across the studies. The influence of the various techniques on union rates, complication rates, and reintervention rates was assessed by a z test on the pooled rates with their corresponding 95% CIs. Assessment of risk of bias and quality of evidence was based on Downs and Black’s “Checklist for Measuring Quality” and Rob 2.0 tool. Certainty of yielded evidence was evaluated with the GRADE system. Seventy-four articles were included on 1781 patients treated for the reconstruction of diaphyseal bone defects, 1496 cases in the inferior limb, and 285 in the upper limb, with trauma being the main cause of bone defect. The meta-analysis identified different outcomes in terms of results and risks. Primary union, complications, and reinterventions were 75%, 26% and 23% for bone allografts and autografts, 91%, 62% and 19% for the bone transport group, and 78%, 38% and 23% for fibular grafts; mean time to union was between 7.8 and 8.9 months in all these groups. Results varied according to the different aetiologies, endoprosthesis was the best solution for tumour, although with a 22% failure rate, while trauma presented a more composite outcome, with fibular grafts providing a faster time to union (6.9 months), while cancellous and cortical-cancellous grafts caused less complications, reinterventions, and failures. The literature about this topic has overall limited quality. However, important conclusions can be made: Many options are available to treat critical-size defects of the diaphysis, but no one appears to be an optimal solution in terms of a safe, satisfactory, and long-lasting outcome. Regardless of the bone defect cause, bone transport techniques showed a better primary union rate, but bone allograft and autograft had fewer complication, reintervention, and failure rates than the other techniques. The specific lesion aetiology represents a critical aspect influencing potential and limitations and therefore the choice of the most suitable technique to address the challenging large diaphyseal defects.

World J Orthop 2022; 13:278-288. [PMID: 35317249 PMCID: PMC8935333 DOI: 10.5312/wjo.v13.i3.278] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 10/11/2021] [Accepted: 02/20/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The Ilizarov bone transport (IBT) and the Masquelet induced membrane technique (IMT) have specific merits and shortcomings, but numerous studies have shown their efficacy in the management of extensive long-bone defects of various etiologies, including congenital deficiencies. Combining their strong benefits seems a promising strategy to enhance bone regeneration and reduce the risk of refractures in the management of post-traumatic and congenital defects and nonunion that failed to respond to other treatments.
AIM To combine IBT and IMT for the management of severe tibial defects and pseudarthrosis, and present preliminary results of this technological solution.
METHODS Seven adults with post-traumatic tibial defects (subgroup A) and nine children (subgroup B) with congenital pseudarthrosis of the tibia (CPT) were treated with the combination of IMT and IBT after the failure of previous treatments. The mean number of previous surgeries was 2.0 ± 0.2 in subgroup A and 3.3 ± 0.7 in subgroup B. Step 1 included Ilizarov frame placement and spacer introduction into the defect to generate the induced membrane which remained in the interfragmental gap after spacer removal. Step 2 was an osteotomy and bone transport of the fragment through the tunnel in the induced membrane, its compression and docking for consolidation without grafting. The outcomes were retrospectively studied after a mean follow-up of 20.8 ± 2.7 mo in subgroup A and 25.3 ± 2.3 mo in subgroup B.
RESULTS The “true defect” after resection was 13.3 ± 1.7% in subgroup A and 31.0 ± 3.0% in subgroup B relative to the contralateral limb. Upon completion of treatment, defects were filled by 75.4 ± 10.6% and 34.6 ± 4.2%, respectively. Total duration of external fixation was 397 ± 9.2 and 270.1 ± 16.3 d, including spacer retention time of 42.4 ± 4.5 and 55.8 ± 6.6 d, in subgroups A and B, respectively. Bone infection was not observed. Postoperative complications were several cases of pin-tract infection and regenerate deformity in both subgroups. Ischemic regeneration was observed in two cases of subgroup B. Complications were corrected during the course of treatment. Bone union was achieved in all patients of subgroup A and in seven patients of subgroup B. One non-united CPT case was further treated with the Ilizarov compression method only and achieved union. After a follow-up period of two to three years, refractures occurred in four cases of united CPT.
CONCLUSION The combination of IMT and IBT provides good outcomes in post-traumatic tibial defects after previous treatment failure but external fixation is longer due to spacer retention. Refractures may occur in severe CPT.

Abstract
INTRODUCTION Traditionally, distraction osteogenesis has been accomplished with an external fixator. All internal transport utilizing magnetic intramedullary nails is a newer technique for bone reconstruction. The Precice Bone Transport Nail is a new implant that allows for noninvasive transport via a magnetically driven motor. AREAS COVERED This report describes the function of the Bone Transport Nail along with the technical considerations on how to successfully manage bone defects with this new technology. Appropriate use of the nail, preoperative planning, intraoperative considerations, and postoperative management are discussed in detail. EXPERT OPINION The Precice Bone Transport Nail utilizes the technology of the original Precice nail to provide an all-internal option for reconstruction of intercalary defects. This obviates the need for an additional plate with a standard Precice nail when performing bone transport and allows for a less invasive option that decreases operating room time. It provides a more cosmetic result than external fixation and avoids the risks of pin tract infection. Preoperative planning is essential to appropriate execution of the operative procedure and to perform a successful transport. A thorough understanding of the nail design and limitations are a prerequisite as this implant is significantly different from a standard intramedullary nail.

Abstract
INTRODUCTION Limb salvage and reconstruction are often challenging and even more so in the limited resource setting. The purpose of this narrative review is to explore the strategies for addressing the unique obstacles and opportunities of limb reconstructive surgery in resource-limited environments globally. METHODS We review (1) the global burden and dimension of the problem, (2) the relevance of orthopedic forums and communication, (3) free and open-access software for deformity analysis and correction, (4) bidirectional learning opportunities, and the value of fellowships and mentoring between resource-rich and resource-limited countries, and (5) how societies like SICOT can help to tackle the problem. Finally, case examples are presented to demonstrate the choice of surgical implants, their availability in regions with limited resources, and how the universal principles of limb reconstruction can be applied, irrespective of resource availability. RESULTS Limb reconstruction can often be life-changing surgery with the goals of limb salvage, improved function, and ambulation. The contradiction of relatively few severe limb deformities in high-income countries (HICs) with abundant resources and the considerable burden of limb deformities in resource-limited countries is striking. Free, open access to education and software planning tools are of paramount importance to achieve this goal of limb reconstruction. Bidirectional learning, i.e., knowledge exchange between individual surgeons and societies with limited and abundant resources, can be reached via fellowships and mentoring. The presented cases highlight (1) fixator-assisted wound closure obliviating the need for plastic surgery, (2) open bone transport, and (3) hinged Ilizarov frames for correction of severe deformities. These cases underline that optimal clinical outcome can be achieved with low-cost and readily available implants when the principles of limb reconstruction are skillfully applied. DISCUSSION Limb lengthening and reconstruction are based on universally applicable principles. These have to be applied regardless of the planning tool or surgical implant availability to achieve the goals of limb salvage and improved quality of life.

Reconstruction of massive tibial defect caused by osteomyelitis using induced membrane followed by trifocal bone transport technique: a retrospective study and our experience. BMC Surg 2021; 21:419. [PMID: 34911504 PMCID: PMC8672610 DOI: 10.1186/s12893-021-01421-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Accepted: 12/02/2021] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE To evaluate clinical outcomes of the application of induced membrane followed by trifocal bone transport technique in the treatment of massive tibial defect caused by osteomyelitis. METHOD A total of 18 eligible patients with tibial defect > 6 cm caused by osteomyelitis who were admitted to our institution from January 2010 to January 2016 and treated by induced membrane followed by trifocal bone transport technique. There were 12 male and 6 females with an average age of 40.4 years old. A detailed demographic data (age, sex, etiology, previous operation time, defect size and location, interval from Masquelet technique to trifocal bone transport technique, external fixation index (EFI), duration of regenerate consolidation and docking union) were collected, bone and functional outcomes were evaluated by Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system. Complications during and in the period of follow up were recorded and evaluated by Paley classification at a minimum follow-up of 2 years. RESULTS The etiology include posttraumatic osteomyelitis in 13 cases and primary osteomyelitis in 5 cases. An average of previous operation time was 3.4 times. Mean tibial defect after radical debridement was 6.8 cm. An average interval duration from formation of induced membrane to trifocal bone transport was 4.8 weeks. An average of EFI was 37.1 days/cm, the duration of regenerate consolidation and docking union were 124.7 days and 186.4 days, respectively. An average time of follow-up after removal of external fixator was 28.5 month without recurrence of osteomyelitis. The bony outcome was excellent in 6 cases, good in 8 cases, fair in 3 cases and poor in 1 case, and functional outcome was excellent in 4 cases, good in 10 cases, fair in 2 cases and poor in 2 cases. The most common complication was pin tract infection which occurred in 15 cases and there were no major complications such as nerve or vascular injury. CONCLUSION Massive tibial defect caused by osteomyelitis can be successfully treated first stage using induced membrane followed by second stage using trifocal bone transport technique, which is an effective method in terms of radical elimination of osteomyelitis with expected clinical outcomes.

Abstract
Segmental bone defects of the tibia are amenable to multiple treatment options including classic bone transport, shortening and then lengthening, induced membrane technique, transport over a nail, free fibular grafting, and medial transport of the ipsilateral fibula. These treatment options have relative advantages and disadvantages, depending on defect size, soft-tissue characteristics, the presence or absence of infection, and associated morbidity. Relatively, few large comparative studies exist, and surgeons are left to their own experience and the opinion of experts within the field to guide surgical decision-making.

Abstract
This clinical practice guideline for the diagnosis and treatment of acute hematogenous osteomyelitis (AHO) in children was developed by a multidisciplinary panel representing Pediatric Infectious Diseases Society (PIDS) and the Infectious Diseases Society of America (IDSA). This guideline is intended for use by healthcare professionals who care for children with AHO, including specialists in pediatric infectious diseases, orthopedics, emergency care physicians, hospitalists, and any clinicians and healthcare providers caring for these patients. The panel's recommendations for the diagnosis and treatment of AHO are based upon evidence derived from topic-specific systematic literature reviews. Summarized below are the recommendations for the diagnosis and treatment of AHO in children. The panel followed a systematic process used in the development of other IDSA and PIDS clinical practice guidelines, which included a standardized methodology for rating the certainty of the evidence and strength of recommendation using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. A detailed description of background, methods, evidence summary and rationale that support each recommendation, and knowledge gaps can be found online in the full text.

Abstract
SUMMARY The challenging problem of long bone infection and limb length difference cannot be addressed using only an antibiotic-coated nonmagnetic static nail. The combined use of resorbable calcium sulfate and magnetic lengthening nails offers a possible solution to this dilemma, as well as for infected nonunions that require compression. We present a combined technique to treat or prevent infection using femoral or tibial intramedullary antibiotic delivery with an absorbable calcium sulfate depot and concomitant internal lengthening or compression using a nail. Adequate débridement is required in cases of established infection and is a prerequisite for this technique.

Abstract
PURPOSE Injuries to the long bones of the upper limb resulting in bone defects are rare but potentially devastating. Literature on the management of these injuries is limited to case reports and small case series. The aim of this study was to collate the most recent published work on the management of upper limb bone defects to assist with evidence based management when confronted with these cases. METHODS Following a preliminary search that confirmed the paucity of literature and lack of comparative trials, a scoping review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) was conducted. A literature search of major electronic databases was conducted to identify journal articles relating to the management of upper limb long bone defects published between 2010 and 2020. RESULTS A total of 46 publications reporting on the management of 341 patients were reviewed. Structural autograft, bone transport, one-bone forearm and the induced membrane technique were employed in an almost equal number of cases. The implemented strategies showed similar outcomes but different indications and complication profiles were observed. CONCLUSION Contemporary techniques for the management of post-traumatic upper limb bone defects all produce good results. Specific advantages, disadvantages and complications for each modality should be considered when deciding on which management strategy to employ for each specific patient, anatomical location, and defect size.

Abstract
INTRODUCTION Although bone transport is generally accepted as the gold standard for the treatment of segmental septic bone defects, some aspects of its practical application are still open to debate. We present our results in this field and compare them with the series published so far. MATERIAL AND METHODS We reviewed all our patients (2010-2018) that underwent a bone transport procedure in the lower limb due to a septic bone defect. We calculated the bone healing index (BHI), the external fixation index (EFI), the rate of complications and the clinical results. We statistically compared our results with 63 publications with a similar scope. RESULTS Thirty-five patients (30 M/5F) with a mean age of 40 years and a mean follow-up of 45 months were included. Bone segment was 24 T/11F and mean defect was 8.4 cm (7.34 T/ 10.73F). Mean global BHI was 45.62 days/cm (48.16 T/40.09F). Mean EFI was 2.37 months/cm. Results were excellent in 9 patients, good in 23 and bad in 3. Bone graft was used in 60% of the cases. DISCUSSION The size of our series is similar to previously published ones, although the mean age of our patients is higher and they present a larger bone defect. BHI of our series is similar to that of other series, although EFI is significantly higher. The number of complications is also in line with the existing literature. CONCLUSION The use of a two-stage technique for managing segmental bone defects of septic origin in the lower extremity is a valid alternative. Our series shows results comparable to the current literature.

Abstract
Background The objective of this systematic review was to evaluate current studies available reporting the antibiotic spacer combined with Ilizarov methods in the treatment of infected nonunion of tibia and to perform meta-analysis of bone results and infection recurrence to assess the efficacy of an antibiotic spacer combined with Ilizarov methods. Methods The MEDLINE, Embase, Cochrane Library, CNKI, and CBM (Chinese Biological Medicine) databases were searched for articles published between January 2000 and July 2020. Assessment of study quality was performed using a modified version of the Newcastle-Ottawa scale. Effect size and 95% confidence intervals were calculated for the main outcome. Heterogeneity was assessed. Fixed-effect modeling and Stata version 15.1 were used to analyze the data. Sensitivity analyses were conducted with the evidence of heterogeneity. Results 11 studies involving 210 patients with infected nonunion of tibia were finally included in our meta-analysis. Bone results and infection recurrence were analyzed based on the single-arm meta-analysis. The average of external fixation index (EFI) was 46.88 days/cm in all studies included. The excellent rate in bone results and the rate of infection recurrence was 65% (95% CI: [0.22, 0.97], I2 = 0.0%, P = 0.932) and 6.99% (95% CI: [0.052, 0.325], I2 = 0.0%, P = 1.000) in patients with infected nonunion of tibia treated with an antibiotic spacer combined with Ilizarov methods. Conclusions Our meta-analysis revealed that the patients with infected nonunion of tibia treated with an antibiotic spacer combined with Ilizarov methods had a high rate of excellent bone results and a low rate of infection recurrence. Therefore, combining the antibiotic spacer with Ilizarov methods may be an applicable choice for repairing and reconstructing infected nonunion of tibia.

Abstract
Tonifying kidney therapy consisting of tonifying kidney yang and yin is the basic principle of Chinese medicine in treating segmental bone defects (SBDs). Previous studies have demonstrated the presence of the differences between tonifying kidney yang and yin in bone metabolism of osteoporosis and distraction osteogenesis models. However, whether the difference between the two tonifying kidney methods in bone repair for the induced membrane (IM) technique occurs or what is the difference remain unclear. Angiogeneic-osteogenic coupling plays an important role in bone repair and the induced membrane couples angiogenesis with the later osteogenesis during the IM process. This study aimed at investigating the effects of tonifying kidney yang (total flavonoids of Rhizoma Drynariae, TFRD) and yin (plastrum testudinis extract, PTE) on angiogenesis and osteogenesis in the IM-treated SBDs. Rats of 6 mm tibia bone defect model treated with IM were divided into five groups: the control group, the model group, the tonifying kidney yang group (TFRD-treated group), the tonifying kidney yin group (PTE-treated group), and the western medicine group. At 4 weeks after insertion of the polymethylmethacrylate (PMMA), three caudal vertebrae from the tail in each rat were implanted into the 6 mm defect gap. Radiographical, histological, immunohistochemical, and immunofluorescent analyses were performed to assess bone and vessel formation at 4 or 12 weeks after insertion of the PMMA, respectively. Our results revealed that TFRD and PTE were beneficial to both angiogenesis and osteogenesis. TFRD exerted a better effect on angiogenesis than PTE and achieved a better result in stage 1 rather than in stage 2 of IM, whereas PTE was superior to TFRD in osteogenesis and achieved a better result in stage 2 instead of stage 1. Collectively, these findings elucidated the beneficial effects of tonifying kidney yang and yin on angiogenesis and osteogenesis of SBD repair during the IM process, as well as the difference that tonifying kidney yang surpasses tonifying kidney yin in angiogenesis while tonifying kidney yin outperforms tonifying kidney yang in osteogenesis, which suggests that the combination between the application of tonifying kidney yang method in stage 1 of IM and tonifying kidney yin method in stage 2 may achieve better repair efficiency.

Abstract
INTRODUCTION Management of the complex non union of tibia is a challenging task due to infection, bony gap, deformity, poor bone quality and poor soft tissue cover at fracture site. The limb reconstruction system (LRS) or Rail fixator has emerged as a viable option for the treatment of the same as it can address most of all above problems. It is more patient friendly and easier to apply in comparison to Ilizarov ring fixator. MATERIAL AND METHODS Twenty two patients (17 males and 5 females) with complex non union of tibia underwent thorough debridement and resection of non viable bone followed by bone transport to fill the gap and then lengthening (8 patients) or acute docking & lengthening (14 patients) by the use of rail fixator. The average time to union, bone gap filled, lengthening achieved, treatment index were measured. The bone and functional outcome assessment was done by ASAMI score. The complications were classified according to Paley's classification. RESULTS Union without residual infection was achieved in 20 (90.1%) patients while 2 patients had failure. As per ASAMI criteria bone results were excellent in 12 (54.5%), good in 5 (22.7%), fair in 3 (13.6%) and poor in 2 (9.1%). Functional results were excellent in 11 (50%), good in 5 (22.72%), fair in 4 (18.18%) and failure in 2 (9%). Mean treatment duration was 8.2 months (range 7-19 months). Mean follow up duration was 11.3 months (range - 8.3 to 22 months). Average lengthening achieved was 4 cm (0-9 cm). Treatment index was 2.1 month/cm. CONCLUSION The monolateral rail fixator is simple, effective, easier to apply and more patient compliant with acceptable functional and radiological outcome.

Abstract
BACKGROUND Bone defects remain challenging to manage. The wide array of treatment options is a testament no single strategy works in every patient. This is more complex if consideration is given to the status of the host and the soft tissues. The choice of treatment should be based on specific patient requirements after taking all variables into account. MATERIALS AND METHODS We present a comprehensive classification system and treatment algorithm to assist with decision-making in management. All potential treatment modalities including amputation are discussed with their relevant pearls and pitfalls. CONCLUSION The proposed classification system may potentially assists with communication, enable patient stratification for assigning the most appropriate treatment modality and guide reporting of treatment outcomes.

Comparison between the induced membrane technique and distraction osteogenesis in treating segmental bone defects: An experimental study in a rat model. PLoS One 2019; 14:e0226839. [PMID: 31860680 PMCID: PMC6924672 DOI: 10.1371/journal.pone.0226839] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Accepted: 12/05/2019] [Indexed: 01/02/2023] Open
Abstract
Previous studies have suggested that treatment plans for segmental bone defects (SBDs) are affected by the bone defect sizes. If the selected treatment was not the most appropriate, it would not contribute to bone healing, but increase complications. The induced membrane technique (IM) and distraction osteogenesis (DO) have been proved to be effective in treating SBDs. However, the differences between the two in therapeutic effects on SBDs with different sizes are still unclear. Thus, we aimed to observe the effects of IM and DO on different sizes of SBDs and to further determine what method is more appropriate for what defect size. Rat models of 4-, 6-and 8-mm mid-diaphyseal defects using IM and DO techniques were established. X-rays, micro-CT, histological and immunohistochemical examinations were performed to assess bone repair. Faster bone formation rate, shorter treatment duration, higher expressions of OPN and OCN and higher parameters of bone properties including bone mineral density (BMD), bone volume/total tissue volume (BV/TV), mineral apposition rate (MAR) and mineral surface/bone surface (MS/BS) were found in 4-mm SBDs treated with DO than in those with IM treatment. However, the results were reversed and IM outperformed DO in bone repair capacity for 8-mm SBDs, while no significant difference emerges in the case of 6-mm SBDs. This study suggests that the therapeutic effects of IM and DO may be subjected to sizes of bone defects and the best treatment size of defects is different between the two. For small-sized SBDs, DO may be more suitable and efficient than IM, but IM has advantages over DO for over-sized SBDs, while DO and IM show similar bone repair capability in moderate-sized SBDs, which would offer a new insight into how to choose DO and IM for SBDs in clinical practice and provide references for further clinical research.

Abstract
The aim of this work was to evaluate the outcome and efficacy of treatment in a homogeneous group of skeletally immature patients with chronic osteomyelitis of the long bones managed by a combination of radical debridement and insertion of tobramycin-impregnated calcium sulfate pellets to fill the bone defect in a single-stage procedure. Between 2011 and 2016, 12 skeletally immature patients were treated surgically by the reported technique. Single-stage surgery using tobramycin-impregnated calcium sulfate pellets in association with systemic antibiotic therapy yields satisfactory outcomes in skeletally immature children presenting chronic osteomyelitis by reducing the risk of occurrence of comorbidities, hospital stays, and healthcare costs.

Abstract
Background Critical-sized bone defects of the tibia are complex injuries associated with significant problems that are difficult to treat, and they are associated with a significant burden of disease in clinical practice; however, the treatment of these cases has still been a challenge for orthopedic surgeons. The aim of this review was to evaluate the current available studies reporting on classical Ilizarov methods in the treatment of infected or noninfected critical-sized bone defects of the tibia, and to perform an analysis of treatment period and complications. Methods This is a narrative review based on a comprehensive literature search among the studies in Pubmed, Scopus and Web of Science articles. The studies included were written in the English language or translated to English and they were published between 2008 and 2018. They were appraised with narrative data synthesis. The primary outcome measures were the external fixation time (EFT), bone union rate, and bone and functional results. Secondary outcomes were complications including docking site problems and solutions. The heterogeneity of the data in the studies which were taken into consideration allowed a narrative analysis. Results Twenty-seven articles with 619 patients were included in this study. These included 6 prospective and 21 retrospective case series. Mean age was 36.1 (range 13–89) years. Of the cases, 88.8% were infected and the remaining 11.2% were noninfected. The external fixation time was 10.75 (range 2.5–23.2) months. The mean bone union rate was 90.2% (range 77–100)%. Radiographic outcome measures were reported in 20 studies. Functional outcome measures were reported in 18 studies. ASAMI (Association for the Study of the Method of Ilizarov) criteria are useful and give reproducible data on patient outcome measurements. Data collected from these studies showed excellent radiological outcomes in 303, good in 143, fair in 31, and poor in 25 patients. Functional outcomes were excellent in 200, good in 167, fair in 58, and poor in 19, where reported. The excellent and good rate in bone results and functional results were 88.8% and 82.6%, respectively. The poor rate in bone results and functional results were 5% and 4.5%. Mean complication rate per patient was 1.22 (range 3–60). The most common complication was pin tract infection (PTI). Its occurrence was 46.6%. Joint stiffness followed PTI with a 25% incidence. The rates of refracture, malunion, infectious recurrence, and amputation, were 4%, 8.4%, 4.58%, and 1%, respectively. Conclusions This narrative review shows that the patients with infected or noninfected critical-sized tibial bone defects treated by Ilizarov methods had a low rate of poor bone and functional results. Therefore, Ilizarov methods may be a good choice for the treatment of infected or noninfected tibial bone defects. The small number of cases in some studies, the absence of homogenity between studies and the fact that most data available are derived from retrospective studies are some of the difficulties encountered in the evaluation of evidence. Level of evidence V.

Abstract
The application value of Masquelet induced membrane technique for the treatment of rat chronic osteomyelitis was explored. A total of 180 male Sprague-Dawley (SD) rats were randomly divided into sham operation group (control group), chronic osteomyelitis model group (model group) and Masquelet induced membrane therapy + chronic osteomyelitis model group (observation group); 60 rats in each group. A rat model of traumatic osteomyelitis was established using a modified blunt trauma method in model and observation group. All rats in observation group were treated with membrane induction technology while in the control group they were not. Postoperative complications, bone healing time and functional status of the affected limbs were recorded. After surgery, no obvious perioperative complications occurred in most of the rats, except that 5 rats experienced partial necrosis at the edge of the flap, and 3 experienced superficial infection around the incision site in the ilium. Primary bone healing was achieved in 50 rats with an average healing time of 15 weeks. Among them, 38 rats restored weight-bearing function after 20 weeks. Seven rats experienced infection after surgery, but complete bone healing was achieved after treatment with induced membrane technique again. Following treatment with induced membrane technique, the rat body weight, body temperature and the number of bacteria in the wound decreased over time. In conclusion, Masquelet induced membrane technique is effective for the treatment of large bone defects in rats after traumatic osteomyelitis. This technique significantly shortens the treatment cycle. The surgical procedure is simple, and the incidence of postoperative complications is low.

Abstract
Objective To evaluate the bone repair efficacy of the new nano-hydroxyapatite (n-HA)/polyurethane (PU) composite scaffold in the treatment of chronic osteomyelitis in tibia. Methods A novel levofloxacin@mesoporous silica microspheres (Lev@MSNs)/n-HA/PU was successfully synthesized. Its surface structure was observed by scanning electron microscopy (SEM). Fifty adult female New Zealand rabbits were randomly selected, and osteomyelitis was induced in the right tibia of the rabbit by injecting bacterial suspension ( Staphylococcus aureus; 3×10 7 CFU/mL), which of the method was described by Norden. A total of 45 animals with the evidence of osteomyelitis were randomly divided into 4 groups, and the right medullary cavity of each animal was exposed. Animals in the blank control group (group A, n=9) were treated with exhaustive debridement only. The remaining animals were first treated by exhaustive debridement, and received implantations of 5 mg Lev@PMMA (group B, n=12), 1 mg Lev@MSNs/n-HA/PU (group C, n=12), and 5 mg Lev@MSNs/n-HA/PU (group D, n=12), respectively. At 12 weeks postoperatively, the right tibia of rabbits were observed by X-ray film, and then gross observation, methylene blue/acid fuchsin staining, and SEM observation of implant-bone interface, as well as biomechanical test (measuring the maximal compression force) were performed. Results X-ray films showed that the infection were severer than those of preoperation in group A, while the control of inflammation and bone healing of rabbits in group D were obviously better than those at preoperation. The gross observation showed extensive bone destruction in group A, a significant gap between bone tissue and the material in groups B and C, and close combination between bone tissue and the material in group D. The histology of the resected specimens showed that there was no obvious new bone formation around the materials in groups B and C, and there was abundant new bone formation around the periphery and along the voids of the materials and active bone remodeling in group D. The SEM observation of the bone-implant interface demonstrated that no new bone formation was observed at the bone-implant interface in groups B and C. However, bony connections and blurred boundaries were observed between the material and host bone tissue in group D. The biomechanical test showed the maximal compression force of groups B and D were significantly higher than that of groups A and C ( P<0.05), but there was no significant difference between groups B and D ( P>0.05). Conclusion The novel synthetic composite Lev@MSNs/n-HA/PU exhibit good antibacterial activities, osteoconductivity, and biomechanical properties, and show great potential in the treatment of chronic osteomyelitis of rabbits.

Abstract
Objective To investigate the appropriate concentration of methicillin-resistant Staphylococcus aureus (MRSA) in establishing chronic femoral osteomyelitis model in rabbits. Methods Forty-eight adult New Zealand white rabbits were randomly divided into 6 groups with 8 rabbits in each group. Animals in groups B, C, D, E, and F were injected 1×10 9, 1×10 8, 1×10 7, 1×10 6, 1×10 5 CFU/mL MRSA on the location of 2 cm of the femoral supracondyle, respectively, and group A was injected with aseptic saline as a control. The general observation were performed at 4 weeks after operation, and the wound secretions were taken for bacteriological examination. The serum C-reactive protein content was detected at preoperation and 2 weeks and 4 weeks after operation. The X-ray, CT scan, and Norden imaging scoring were performed at 4 weeks after operation. At 4 weeks after operation, the animals were sacrificed, and the specimens were observed and evaluated by general scores; and the HE staining and histological score were also performed. Results Five rabbits died of severe infection in group B, 2 died in group C, and no rabbit died in groups D, E, and F. General observation showed that the incision healed without soft tissue swelling in group A; most animals had visible incision swelling and sinus formation, femoral thickening, bone destruction, and damage decreased with the decreasing of the concentration of liquid bacterial in groups B-D; the infection signs were seen in groups E and F, and the degree of infection were less than that of group D. Bacteriological examination showed that fistula formation animal in groups B, C, D, and E were cultured with positive results, and with the decrease of concentration, the number of animal fistula formation decreased gradually; and bacteriological culture did not be performed in group F because of no sinus formation. There was no significant difference in the content of C-reactive protein between groups before operation ( P>0.05). The contents of C-reactive protein in groups B-F were significantly higher than those in group A at 2 and 4 weeks after operation ( P<0.05). At 4 weeks after operation, the content of C-reactive protein was in the order of groups B, C, D, E, F, and A in turn from high to low, showing significant differences between groups ( P<0.05). Imaging examination showed that there was no soft tissue swelling and bone destruction in group A; bone destruction, massive sequestrum formation, and soft tissue swelling were found in groups B and C; bone destruction was observed in groups D and E, and the degree of sequestrum formation was not as good as that in group C; and there was a small amount of bone infection in group F. The Norden scores in groups B-F were significantly higher than that in group A, and in groups B and C than those in groups D, E, and F, and in groups D and E than that in group F ( P<0.05); there was no significant difference between groups B and C, and between groups D and E ( P>0.05). The specimens general observation scores in groups B-F were significantly higher than that in group A, while in groups B and C than those in groups D, E, and F ( P<0.05); there was no significant difference between groups D, E, and F ( P>0.05). HE staining showed that the structure of bone trabecula in group A was clear and the structure was arranged neatly; in groups B-F, trabecular bone destruction and inflammatory cell infiltration were seen and the degree gradually decreased. The histological scores in groups B-F were significantly higher than that in group A, and in group B than those in groups C-F, in groups C and D than that in group F ( P<0.05); there was no significant difference between groups C, D, and E, and between groups E and F ( P>0.05). Conclusion The optimal MRSA concentration of rabbit model of chronic osteomyelitis of femur is between 1×10 6 and 1×10 7 CFU/mL.

Abstract
INTRODUCTION Bone defect is a difficult problem in orthopedics. The treatment conventionally relies on techniques such as induced membrane, grafts, and elongations. The reintegration of an externalized osseous fragment involves significant infectious risks but is essential in certain situations. CASE REPORT We report the case of a 10 cm traumatic bone loss of the right distal femur in a 35-year-old woman. Treatment consisted of paring, reintegration and stabilization by the external fixative. The 5-year follow-up was satisfactory with good consolidation and good function of the limb. CONCLUSION The reintegration of a bone fragment of limb expelled onto the soil is rare. We tried it because the response time was very short, but also and especially because the fragment was expelled on very hot bitumen. These two elements limited the risk of infection and favored the osseointegration of the fragment. We have not found a similar case reported in the literature allowing comparisons and recommendations.

Abstract
PURPOSE The purpose of this study was to compare the outcome of combined circular external fixation and cemented polymethylmethacrylate (PMMA) spacer application between a cohort of patients with grade 3 open fractures and infected tibial nonunions and concomitant segmental bone loss. METHODS The study was designed as a retrospective cohort study. All patients who were treated for complex tibial fractures or infected nonunions with segmental bone loss between 2009 and 2013 were included if they were aged between 16 years and 60 years, sustained acute traumatic grade 3 open tibial fractures, presented with infected nonunion, and were followed up for a minimum of 12 months. Patients with a history of ipsilateral tibial fractures, contralateral lower extremity fractures, polytrauma, chest, or abdominal trauma and patients with head injuries were excluded. Both groups were treated with aggressive debridement, circular external fixation, and antibiotic-impregnated PMMA spacer. Outcome measures were the time in the external fixator (EFT) and the external fixation index (EFI). RESULTS Twenty-four patients with a mean age of 32 ± 14.7 years were included. Twelve patients with a mean age of 32 + 14 years and a mean bone defect of 82 + 36 mm were treated for acute complex grade 3 open tibial fractures, and 12 patients with a mean age of 35.1 + 15.7 years and a mean bone defect of 50 + 26 mm were treated for infected nonunions. There was no significant difference ( p = 0.44) between the groups for EFT (249 ± 99 days-tibial fractures; 255 ± 142 days-infected nonunion). There were significant between group differences ( p = 0.027) for EFI (37.3 ± 9.1 cm/days-tibial fractures; 56 ± 14.5 cm/days-infected nonunion). CONCLUSION The findings of this study suggest that patients were treated for infected nonunion with segmental bone loss using circular external fixation, distraction osteogenesis, and antibiotic-impregnated PMMA spacers, and the spacers may not offer any advantage over a conventional approach using the principles of osteogenesis only. In contrast, antibiotic-impregnated spacers for open tibial trauma were advantageous and reduced the EFI considerably.

Abstract
OBJECTIVES To analyze long-term functional outcomes in patients with posttraumatic infected tibial nonunions having undergone bone transport with hexapod external fixator. DESIGN Retrospective cohort study. SETTING Level 1 trauma center. PATIENTS/PARTICIPANTS Thirty-eight patients with infected nonunions of the tibia. INTERVENTION Resection of nonunion with application of stacked hexapod external fixator for bone transport. MAIN OUTCOME MEASUREMENTS Functional outcome was measured using the short Musculoskeletal Functional Assessment (sMFA). Parameters measured included age, sex, presence of diabetes, smoking, use of a free flap, bone defect size, length in frame, external fixation index, and direction of lengthening. RESULTS The mean sMFA score for the entire group was 27.1. Average patient age was 46.8 ± 12.7 years, 74% patients were male, 8% were diabetic, and 29% were smokers. Seventeen patients had soft-tissue defects that required a free flap. Smokers had higher degrees of disability compared with nonsmokers (39 ± 16 vs. 22 ± 14, P = 0.011). Patients requiring adjunctive stabilization had worse functional scores compared with those who did not receive adjunctive stabilization (33 ± 17 vs. 22 ± 15, P = 0.049). Sixteen patients returned 2 sMFA surveys at different time points after completion of bone transport. Initial average sMFA score was 26.5 at a mean of 25.3 months; subsequent sMFA scores averaged 19.4 at a mean of 98.8 months. CONCLUSIONS Stacked hexapod external fixator bone transport is a reliable technique for infected nonunion of the tibia with bone loss. Improved sMFA scores can be expected from 2 to 8 years, suggesting full recovery takes longer than previously anticipated. Limb salvage with hexapod bone transport is justified over time.

Abstract
OBJECTIVES The stacked hexapod bone transport technique is an effective treatment for infected tibial nonunions with bone loss. The purpose of this study was to evaluate the patients' risk factors and timing for requiring adjunctive stabilization. DESIGN Retrospective cohort study. SETTING Level 1 trauma center. PATIENTS/PARTICIPANTS Seventy-five patients with infected posttraumatic nonunions of the tibia. INTERVENTION Resection of nonunion with application of stacked hexapod frame for bone transport. MAIN OUTCOME MEASUREMENTS Parameters measured included age, sex, diabetes, smoking, use of a free flap, bone defect size, length in frame, external fixation index, and direction of lengthening. Outcomes recorded: removal of frame, below knee amputation, or adjunctive stability. Further analysis evaluated location of nonunion, timing of adjunctive stabilization, and type of fixation. RESULTS The average patient age was 45.7 ± 12.5 years, 76% patients were men, 11% were diabetic, and 44% were smokers. Forty two percent had soft tissue defects that required a free flap. Thirty-eight patients had removal of frame, whereas 36 patients required adjunctive stability of the hexapod frame. Patient receiving adjunctive stabilization had a longer length of time in the hexapod frame (P = 0.026) and were more likely to require a free flap (P = 0.053). Ninety-three percent docking site nonunions occurred after the removal of the frame (P = 0.032); whereas 79% regenerate nonunions occurred before the hexapod frame was removed (P = 0.029). CONCLUSIONS The use of a hexapod frame for the infected tibial nonunions with bone loss is an effective method for achieving union and eradicating infection in a difficult orthopaedic patient population. Use of adjunctive stabilization is a reasonable technique to address delayed regenerate and docking site nonunions. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
OBJECTIVE To evaluate the clinical outcomes and complications of segmental prosthetic reconstruction for pathological diaphyseal femoral fractures secondary to metastatic tumors. METHODS Between 2011 and 2015, we retrospectively evaluated 16 patients (6 men and 10 women; 64.5 ± 11.4 years old at diagnosis) who underwent prosthetic reconstruction after segmental resection of diaphyseal femoral fractures due to metastatic lesions. Visual analog scale (VAS), functional outcomes, implant-related complications, and Mean postoperative Musculoskeletal Tumor Society (MSTS) score for each patient were collected. RESULTS The mean length of bone defect was 10.2 ± 2.6 cm (range, 8-16 cm); follow-up was 9 ± 6.8 months (range, 2-25 months) for all patients, and 24 months (23 and 25 months) for the 2 patients still alive. At final follow-up, 14 patients were dead, indicating a mean survival of 6.9 ± 3.6 months (range, 2-14 months). Mean preoperative VAS score was 8.5 ± 1.0, which decreased to 2.5 ± 1.3 at day 2 postoperatively, indicating significant pain relief (P < 0.05). The MSTS score for lower extremities was 84.6% (range, 73%-90%). The range of motion and function of adjacent joints was within the normal limits in all cases. Three patients (33%) developed complications, including aseptic loosening because of disease progression (1), infection (1), and peri-prosthesis fracture (1). CONCLUSION These findings demonstrated that this approach greatly relieves pain, and yields satisfactory functional outcomes with fewer complications in patients with pathological femoral fractures secondary to metastatic tumors; however, survival was not significantly improved.

Abstract
INTRODUCTION The purpose of this study was to describe a standardized staged approach, "The Road to Union", for the reconstruction of isolated complex tibial trauma, both acute and chronic in nature. METHODS This retrospective study included all patients treated for complex tibial trauma at a specialized limb reconstruction centre, including acute open fracture as well as infected and aseptic non-unions. This standardized approach includes eight specific steps, employed in sequence. The time in external fixation (EFT), the external fixation index (EFI), and the distraction consolidation index (DCI) were the primary outcome measures. The relationship between EFI and DCI was assessed using Pearson's moment correlations. RESULTS Thirty-two patients with a mean age of 34.7±14.2years were included; 12 were treated for complex open tibial fractures with bone loss, 13 for infected non-unions, and 6 for aseptic non-union. The mean bone defect was 66±32mm. The total EFT was 42.5±14.8 weeks; the EFI measured 51.9±25.3 days/cm, and the DCI measured 48.3±21.4 days/cm. Union was achieved in 29 out of 32 patients (91%), and there was a strong and significant relationship between EFI and DCI (r=0.92, p=0.0001) measurements. Pin site infections were observed in 11 patients, and 3 patients had persistent non-union. Three patients underwent delayed amputations when reconstructive procedures were unable to achieve union. CONCLUSION The findings of this study demonstrate that a standardized staged treatment protocol of debridement, circular external fixation, soft-tissue management, distraction osteogenesis, and functional rehabilitation can result in a high rate of union in cases of complex tibial trauma, both acute and chronic in nature.

Abstract
Chronic osteomyelitis represents a progressive inflammatory process caused by pathogens, resulting in bone destruction and sequestrum formation. It may present with periods of quiescence of variable duration, whereas its occurrence, type, severity and prognosis is multifactorial. The ‘gold standard’ for the diagnosis of chronic osteomyelitis is the presence of positive bone cultures and histopathologic examination of the bone. Its management remains challenging to the treating physician, with a multidisciplinary approach involving radiologists, microbiologists with expertise in infectious diseases, orthopaedic surgeons and plastic surgeons. Treatment should be tailored to each patient according the severity and duration of symptoms, as well as to the clinical and radiological response to treatment. A combined antimicrobial and surgical treatment should be considered in all cases, including appropriate dead space management and subsequent reconstruction. Relapse can occur, even following an apparently successful treatment, which has a major impact on the quality of life of patients and is a substantial financial burden to any healthcare system.

Two stage management of Cierny-Mader type IV chronic osteomyelitis of the long bones. Injury 2017; 48:511-518. [PMID: 28088375 DOI: 10.1016/j.injury.2017.01.007] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2016] [Revised: 09/15/2016] [Accepted: 01/01/2017] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Cierny-Mader (C-M) type IV chronic osteomyelitis represents a complex clinical challenge with permeation of extensive bone and soft tissue involvement. Aggressive debridement through viable tissue margin includes en bloc resection improves the odds of eradication of infection, which creates large bone and soft tissue loss in treating this type of osteomyelitis. The potentially large defects increase reconstruction problems with traditional reconstruction technique. The newly staged induced membrane technique presents length-independent, potential as an alternative reconstruction method for segmental bone defects due to type IV chronic osteomyelitis. The purpose of this study was to assess the result and related factors of C-M type IV chronic osteomyelitis treated with staged methods of aggressive debridement and induced membrane technique. METHODS From January 2012 to January 2014, 36 consecutive adult patients of C-M type IV chronic osteomyelitis were treated by this staged method in our clinical center with a minimum of 2-years follow-up. The clinical and imaging results were retrospectively analyzed. RESULTS Five patients had a second debridement and eight needed a local flap transfer to cover the wound in the first stage. Patients formed a mean of 5.5cm (range: 2-10.9) segmental bone defect; Sixteen patients had autograft and twenty had autograft mixed allograft in the second stage. The mean follow-up time was 29.5 months (range: 24-45). No patients required amputation. Bone union was achieved in all patients. Clinical eradication of osteomyelitis was achieved in 35 (97%) patients, 35 (97%) patients were able to walk independently, and 31patients (86%) returned to work. Patients returned to a mean of 82% (46.3%-100%) lower extremity function. Bone union time was not dependent on the length of bone defect, but associated with the infection site (p=0.005) and age (p=0.005). CONCLUSIONS Staged methods of aggressive debridement and induced membrane technique seems to be a simple, reliable and effective for the treatment of C-M type IV chronic osteomyelitis. Advanced age and poor soft tissue envelope may have adverse affects and are relative contraindications. The combined assessment and management of such patients with a plastic surgeon are advocated.

Abstract
PURPOSE Chronic osteomyelitis and infected nonunion are relatively rare conditions in pediatric patients and are more frequently seen in developing countries. Although relatively rare, they are medically and surgically challenging. Here we report a novel surgical technique used to manage five patients with chronic osteomyelitis of long bones. METHODS Five skeletally immature patients with chronic osteomyelitis and infected nonunion of the long bones were treated surgically between 2010 and 2014 by a combination of resection of necrotic infected bone, debridement of surrounding soft tissue, and application of antibiotic-laden cement spacer inducing periosteal membrane before final bone reconstruction. Once inflammatory markers normalized, all the patients were re-operated for cement removal, bone graft substitution, and concomitant osteosynthesis of the affected bone, if needed. All patients underwent MRI, CT scan, and laboratory evaluation prior to surgery. The antibiotic regimen was started empirically and then adjusted according to culture and sensitivity results. RESULTS Mean patient age at the time of diagnosis was 11 years (range 4-14), and all patients had at least 2-year follow-up (range 2-5). At last follow-up, clinical and laboratory evaluation had normalized, the bone had healed, and all patients had resumed daily living and sports activities. CONCLUSION Surgical debridement is the standard approach to chronic osteomyelitis. Use of antibiotic-laden cement is recommended to penetrate local infection, with antibiotic therapy playing an adjunctive role. The cement also induces membrane formation that aids bone reconstruction. LEVEL OF EVIDENCE IV.

Abstract
Critical-sized bone defects present a significant burden to the medical community due to their challenging treatment. However, a successful limb-salvaging technique, the Masquelet Technique (MT), has significantly improved the prognosis of many segmental bone defects in helping to restore form and function. Although the Masquelet Technique has proven to be clinically effective, the physiology of the healing it induces is not well understood. Multiple modifiable factors have been implicated by various surgical and research teams, but no single factor has been proven to be critical to the success of the Masquelet Technique. In this review the most recent clinical and experimental evidence that supports and helps to decipher the traditional Masquelet, as well as the modifiable factors and their effect on the success of the technique are discussed. In addition, future developments for the integration of the traditional Masquelet Technique with the use of alternative biomaterials to increase the effectiveness and expand the clinical applicability of the Masquelet Technique are reviewed.
