A scoping review. Eur J Trauma Emerg Surg 2024:10.1007/s00068-024-02478-y. [PMID: 38446155 DOI: 10.1007/s00068-024-02478-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Accepted: 02/19/2024] [Indexed: 03/07/2024]
Abstract
PURPOSE Infected nonunion of the tibia with a large segmental bone defect is a complex and challenging condition for the patient and surgeon. This scoping review was conducted to identify existing evidence and knowledge gaps regarding this clinical scenario. Secondly, the objective of this study was to search for a valid recommendation on the optimal treatment. METHODS A comprehensive search was conducted in the bibliographic databases: PubMed, Embase.com, and Web of Science Core Collection. Studies reporting on bone transport techniques, the Masquelet technique, and vascularized fibular grafts in bone defects greater than 5 cm were included. Bone healing results and functional results were compared according to duration of nonunion, infection recurrence, bone consolidation, complication rate, external fixation time, and time until full weight-bearing. RESULTS Of the 2753 articles retrieved, 37 studies could be included on bone transport techniques (n = 23), the Masquelet technique (n = 7), and vascularized fibular grafts (n = 7). Respective bone union percentages were 94.3%, 89.5%, and 96.5%. The percentages of infection recurrence respectively were 1.6%, 14.4% and 7.0%, followed by respectively 1.58, 0.78, and 0.73 complications per patient. CONCLUSION Bone transport was found to be the most widely studied technique in the literature. Depending on the surgeon's expertise, vascularized fibular grafts may be held as a favourable alternative. This review indicates that further high-quality research on large bone defects ( ≥ 5 cm) in patients with infected tibial nonunions is necessary to gain more insight into the potentially beneficial results of vascularized fibular grafts and the Masquelet technique.

[PMID: 37890289 DOI: 10.1016/j.injury.2023.111130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 09/29/2023] [Accepted: 10/13/2023] [Indexed: 10/29/2023]
Abstract
INTRODUCTION The segmental bone defects post open distal femur fracture presents a reconstructive challenge, which often requires extreme solutions. The present study reviewed a new treatment strategy which used a cylindrical titanium mesh cage as an adjunct to the Masquelet technique. METHODS We retrospectively reviewed a consecutive series of 23 patients treated for segmental bone defects post open distal femur fracture using a titanium mesh cage combined with the Masquelet technique under a 2-staged protocol in our institution from 2017 to 2021. The study group consisted of 13 men and 10 women with an average age of 44.1 years. The surgical debridement was performed with antibiotic polymethylmethacrylate (PMMA) cement spacer implanted into the bone defect combined with cement-wrapped plate stabilization, or antibiotic beads with vacuum sealing drainage (VSD) to cover the wound. The second stage of the Masquelet technique for bone defect repair began at least 4-6 weeks after the first stage, once all signs of possible infection were eliminated. After the cement spacer was removed, the definitive reconstruction was completed with exchange to a cylindrical titanium mesh cage filled with cancellous autograft within the induced membrane. The bone defect with cage was stabilized with a distal femoral Less Invasive Stabilization System (LISS). The radiological and clinical records of the enrolled patients were retrospectively analyzed. RESULTS The mean follow-up was 38.6 months. The average number of operations before the second stage was 1.3. The mean interval between the two stages was 12.7 weeks. The average length of the defect measured 8.3 cm (ranging from 6.1 to 12.4 cm). All the defects filled with autograft within the cage achieved bony union, with a mean healing time of 8.4 months. At the latest follow-up, the mean knee extension measured 6.2° (ranging from 0° to 20°), and the mean flexion measured 101.8° (ranging from 60° to 120°). Complications included two instances of superficial stitch abscess, which eventually healed. CONCLUSIONS The use of a titanium cage implanted into an induced membrane in a 2-staged Masquelet protocol could achieve satisfactory clinical outcomes in cases of segmental defects following open distal femur fractures.

BMC Musculoskelet Disord 2023; 24:891. [PMID: 37968675 PMCID: PMC10652567 DOI: 10.1186/s12891-023-07001-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 10/30/2023] [Indexed: 11/17/2023] Open
Abstract
BACKGROUND Ilizarov method has become one of primary methods for treating bone defects. Currently, there is growing trend in the application of modified Ilizarov methods (e.g., applying unilateral external fixators or with flap tissue) and its combined methods (e.g., Ilizarov method with antibiotic spacer or internal fixation) to manage bone defects. However, there is a lack of studies with systematical evaluation of the clinical effects of these evolving methods. This study aimed to conduct a systematic review and meta-analysis for overall evaluating the clinical effects on long bone defects of lower extremity in Ilizarov methods and its combined methods. METHODS Studies were identified in three electronic databases (Pubmed, Embase and Cochrane Library) from the earliest indexing year through November 01, 2022, and relevant data were extracted subsequently. The total number of participants, number of participants with bone unions, bone result or functional result, and related complications including pin infection, pin loosening, pain, refracture, limb discrepancy, malalignment, joint stiffness, recurrent infection, and amputation were extracted in this study. Then, union rate (defined as the proportion of patients who achieved bone unions) and specific complication incidence rate (defined as the proportion of patients who experienced specific complication) were pooled estimated respectively. Relative risk (RR) was used for comparing the clinical effects among various Ilizarov technique. RESULTS Sixty-eight case series studies, 29 comparative studies, and 3 randomized clinical trials were finally included. The union rate of Ilizarov methods was 99.29% (95% CI: 98.67% ~ 99.86%) in tibial defects and 98.81% (95% CI: 98.81% ~ 100.00%) in femoral defects. The union rate of Ilizarov method with antibiotic spacer and intramedullary nail in tibial defects was 99.58% (95% CI: 98.05% ~ 100.00%) and 95.02% (95% CI: 87.28% ~ 100.00%), respectively. Compared to the Ilizarov methods, the union rate of the Ilizarov method with antibiotic spacer in tibial defects increased slightly (RR = 1.02, 95% CI: 1.01 ~ 1.04). Meanwhile, compared to Ilizarov methods, we found lower excellent rate in bone result in Ilizarov method with antibiotic spacer, with the moderate to high heterogeneity. Compared to the Ilizarov method, lower rate of pin infection, higher rate of recurrent infection and amputation were observed in Ilizarov method with intramedullary nail, however, the findings about the comparison of pin infection and recurrent infection between the two groups were presented with high degree of statistical heterogeneity. CONCLUSION Our study confirmed the reliable treatment of Ilizarov methods and its combined technique on long bone defects, and founded there were significant differences on some complications rate between Ilizarov methods and its combined technique. However, the findings need to be confirmed by further studies.

Masquelet Technique for the Tibia: A Systematic Review and Meta-Analysis of Contemporary Outcomes. J Orthop Trauma 2023; 37:e36-e44. [PMID: 36026545 DOI: 10.1097/bot.0000000000002480] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 08/22/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To systematically review outcomes of the Masquelet "induced membrane" technique (MT) in treatment of tibial segmental bone loss and to assess the impact of defect size on union rate when using this procedure. DATA SOURCES PubMed, EBSCO, Cochrane, and SCOPUS were searched for English language studies from January 1, 2010, through December 31, 2019. STUDY SELECTION Studies describing the MT procedure performed in tibiae of 5 or more adult patients were included. Pseudo-arthrosis, nonhuman, pediatric, technique, nontibial bone defect, and non-English studies were excluded, along with studies with less than 5 patients. Selection adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. DATA EXTRACTION A total of 30 studies with 643 tibiae were included in this meta-analysis. Two reviewers systematically screened titles or abstracts, followed by full texts, to ensure quality, accuracy, and consensus among authors for inclusion or exclusion criteria of the studies. In case of disagreement, articles were read in full to assess their eligibility by the senior author. Study quality was assessed using previously reported criteria. DATA SYNTHESIS Meta-analysis was performed with random-effects models and meta-regression. A meta-analytic estimate of union rate independent of defect size when using the MT in the tibia was 84% (95% CI, 79%-88%). There was no statistically significant association between defect size and union rate ( P = 0.11). CONCLUSIONS The MT is an effective method for the treatment of segmental bone loss in the tibia and can be successful even for large defects. Future work is needed to better understand the patient-specific factors most strongly associated with MT success and complications. LEVEL OF EVIDENCE Therapeutic Level IV.

Masquelet-Ilizarov technique for the management of bone loss post debridement of infected tibial nonunion. INTERNATIONAL ORTHOPAEDICS 2022; 46:1937-1944. [PMID: 35773530 PMCID: PMC9372116 DOI: 10.1007/s00264-022-05494-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 06/19/2022] [Indexed: 10/29/2022]
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.

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.

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
BACKGROUND We aimed to compare the effectiveness and complications of a novel piston technique versus the Ilizarov technique for the repair of bone defects after lower limb infection. PATIENTS AND METHODS We retrospectively reviewed 41 patients who had been treated at our department for lower extremity bone defects following osteomyelitis. There were 38 men and three women with a mean age of 43.41 (range, 12-69 years). The infected bone defects involved 36 tibias and five femurs. The piston technique (PT, group A) was used in 12 patients and the Ilizarov technique (IT, group B) in 29 patients. The mean follow-up period was 28.50 months (PT) and 29.90 months (IT). The modified Application of Methods of Illizarov (ASAMI) criteria was used to evaluate bone healing and functional recovery. RESULTS Complete eradication of the infection and union of docking sites were accomplished in both groups. The mean external fixator index (EFI) was 42.32 days/cm in group A versus 58.85 days/cm in group B (p < 0.001). The bone outcomes were similar between groups A and B (p = 0.558) (excellent [9 vs. 19], good [3 vs.10]); group A showed better functional outcomes than group B (p < 0.05) (excellent [7 vs. 6], good [4 vs. 12], fair [0 vs. 10] and poor [1 vs. 1]). Pain was the most common complaint during follow-up, and group A had fewer cases of pin tract infection (1 vs. 6), adjacent joint stiffness (3 vs. 8), and delayed healing of the joint (0 vs. 3). CONCLUSIONS Satisfactory bone healing can be achieved by using both PT and IT, although PT demonstrated better functional results, lower EFI, and allowed early removal of the external fixation. We found that this novel piston technique can improve the comfort of patients, reduce the incidence of complications, and provide rapid and convenient rehabilitation.

Abstract
OBJECTIVES To develop a post-traumatic bone defect classification scheme and complete a preliminary assessment of its reliability. DESIGN Retrospective classification. SETTING Tertiary referral trauma center. PATIENTS/PARTICIPANTS Twenty open fractures with bone loss. INTERVENTION Assignment of a bone defect classification grade. MAIN OUTCOME MEASUREMENTS Open fractures were classified based on orthogonal radiographs, assessing the extent and local geometry of bone loss, including D1-incomplete defects, D2-minor/subcritical (complete) defects (<2 cm), and D3-segmental/critical-sized defects (≥2 cm). Incomplete defects (D1) include D1A-<25% cortical loss, D1B-25%-75% cortical loss, and D1C->75% cortical loss. Minor/subcritical (complete) defects (<2 cm) (D2) include D2A-2 oblique ends allowing for possible overlap, D2B-one end oblique/one end transverse, and D2C-2 transverse ends. Segmental/critical-sized Defects (≥2 cm) include D3A-moderate defects, 2 to <4 cm; D3B-major defects, 4 to <8 cm; and D3C-massive defects, ≥8 cm. Reliability was assessed among 3 independent observers using Fleiss' kappa tests. RESULTS Interobserver reliability demonstrated the classification scheme has very good agreement, κ = 0.8371, P < 0.0005. Intraobserver reliability was excellent, κ = 1.000 (standard error 0.1478-0.1634), P < 0.00001. Interobserver reliability for the distinction between categories alone (D1, D2, or D3) was also excellent, κ = 1.000 (standard error 0.1421-0.1679), P < 0.00001. CONCLUSIONS This classification scheme provides a robust guide to bone defect assessment that can potentially facilitate selection of the most appropriate treatment strategy to optimize clinical outcomes.

A Systematic Review and Meta-Analysis of Combined Antibiotic Spacer with Ilizarov Methods in the Treatment of Infected Nonunion of Tibia. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6668617. [PMID: 33532493 PMCID: PMC7834795 DOI: 10.1155/2021/6668617] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 12/28/2020] [Accepted: 01/04/2021] [Indexed: 12/24/2022]
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
Aim and objective The purpose of this study was to compare clinical results following complex proximal, midshaft, and distal tibial fractures and investigate whether there are differences in outcomes between these locations. Materials and methods Patients between 18 years and 65 years of age and minimum follow-up of 12 months with complex tibial fractures treated with a circular ring fixator were included. Functional outcomes were assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) functional and bone scores, Foot Function Index (FFI), Four Step Square Test (FSST), and Timed Up and Go Test (TUG). Quality of life was assessed by the EQ-5D score. Results A total of 45 patients were included: proximal fractures, n = 11; midshaft fractures, n = 17; and distal fractures, n = 17. ASAMI functional (p = 0.8) and bone scores (p = 0.3) were not different. Excellent and good bone scores were achieved in >90% in all groups. FFI was 30.9 + 24.7 in the proximal group, 33.9 + 27.7 in the midshaft group, and 28.8 + 26.9 in the distal group (p = 0.8). TUG was 9.0 + 2.7 sec in the proximal group, 9.0+3.5 in the midshaft group, and 8.5+2.0 in the distal group (p = 0.67). FSST was 10.7 + 2.5 sec in the proximal, 10.3 + 3.8 in the midshaft, and 8.9 + 1.8 in the distal fracture groups (p = 0.5). EQ-5D index value was highest in the distal (0.72), lowest in the proximal (0.55), and 0.70 in the midshaft fracture groups (p = 0.001). EQ-5D VAS was significantly different between the proximal (65) and midshaft (82.3) (p = 0.001) and between the distal (75) and proximal (65) fracture groups (p = 0.001). Conclusions The results of this study suggest that the functional outcomes between proximal, midshaft, and distal complex tibial fractures are comparable. Their ability to ambulate afterward is comparable to age-related normative data, but complex tasks are more difficult and better compared to the ambulating ability of a healthy population aged 65 to 80 years. Patients with proximal tibial fractures had significantly more disability by at least one functional level and/or one health dimension.

Abstract
INTRODUCTION Optimal treatment for acute post-traumatic bone loss in the tibia remains unclear. Distraction osteogenesis (DO) and induced membrane technique (IM) have been established as the mainstays of treatment. Aim of this article is to review the current evidence regarding the use of these two methods. METHODS A review of the MEDLINE database was performed with strict inclusion and exclusion criteria focusing on treatment of the acute bone loss after open tibia fractures with DO and IM. Bone union rate was taken as the primary outcome and infection rate as secondary outcome. RESULTS Four studies out of 78 on the use of the DO and three studies out of 18 on the use of the IM technique matched the inclusion criteria. Union rate in the DO group ranged between 92% and 100%, with infection rates between 0 and 4%. In the IM group, union was reached in 42% to 100% of cases, with septic complications occurring in 12% to 43%. Differences in union rate and infection rate reached statistical significance. DISCUSSION We found a considerable evidence gap regarding treatment of bone loss in high grade open tibia fractures. The limitations of our study prevented us from drawing clear causative conclusions on the results. Although our study points to higher union rates and lower infection rate with the use of the DO technique, the results remain preliminary and further high-level evidence is needed to establish the roles of DO and IM in treatment of acute bone loss in open tibia fractures.

Comparison between Tonifying Kidney Yang and Yin in Treating Segmental Bone Defects Based on the Induced Membrane Technique: An Experimental Study in a Rat Model. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:6575127. [PMID: 33424987 PMCID: PMC7781691 DOI: 10.1155/2020/6575127] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 09/24/2020] [Accepted: 11/12/2020] [Indexed: 02/08/2023]
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
OBJECTIVE To study the effectiveness of trifocal bone transport by using monolateral rail system in the treatment of bone defects caused by post-traumatic tibial osteomyelitis. METHODS The clinical data of 28 patients with tibial defects caused by post-traumatic osteomyelitis treated with trifocal bone transport technique by using monolateral rail system between January 2012 and June 2017 were retrospectively analyzed. There were 26 males and 2 females, aged 22-59 years (mean, 41.3 years). The causes of injury included 13 cases of traffic accident injury, 9 cases of falling from height, 4 cases of heavy object injury, and 2 cases of crushing injury. The disease duration was 4.5-17.0 months (mean, 7.1 months). The length of bone defect was 6.5-16.8 cm (mean, 10.3 cm). And the range of soft tissue defect ranged from 3.5 cm×2.0 cm to 18.0 cm×11.0 cm. The bone transporting time, external fixation time, duration of regenerate consolidation, and external fixation index were recorded, and the complications were observed. At last follow-up, the bone and functional results were evaluated according to the criteria given by Association for the Study and Application of the Method of the Ilizarov (ASAMI). RESULTS All patients were successfully followed up after removing the external fixator with an average of 35 months (range, 24-65 months). The bone transporting time was 41-136 days (mean, 60.2 days), the external fixation time was 7.5-20.0 months (mean, 13.4 months), the external fixation index was 1.1-1.9 months/cm (mean, 1.4 months/cm), the duration of regenerate consolidation was 6.0-16.5 months (mean, 10.5 months). Pin tract infection occurred in 12 cases, delayed union on docking site was occurred in 9 cases, axial deviation was observed in 2 cases, poor regenerate consolidation was presented in 1 case, and refracture on docking site after fixator removal was occurred in 1 case. There was no recurrence of infection, amputation, vascular and neurologic complications, and osteofascial compartment syndrome. At last follow-up, according to ASAMI criterion, the bone healing results were excellent in 17 cases, good in 7 cases, and fair in 4 cases, with an excellent and good rate of 85.7%; the functional results were excellent in 15 cases, good in 10 cases, and fair in 3 cases, with an excellent and good rate of 89.3%. CONCLUSION Trifocal bone transport by using monolateral rail system is an effective method in the treatment of bone defect caused by post-traumatic osteomyelitis which can reduce bone transport time, external fixation time, and complications.

Abstract
BACKGROUND Ilizarov non-free bone plasty is a method of distraction osteogenesis using the Ilizarov apparatus for external fixation which originated in Russia and was disseminated across the world. It has been used in long bone defect and nonunion management along with free vascularized grafting and induced membrane technique. However, the shortcomings and problems of these methods still remain the issues which restrict their overall use. AIM To study the recent available literature on the role of Ilizarov non-free bone plasty in long bone defect and nonunion management, its problems and the solutions to these problems in order to achieve better treatment outcomes. METHODS Three databases (PubMed, Scopus, and Web of Science) were searched for literature sources on distraction osteogenesis, free vascularized grafting and induced membrane technique used in long bone defect and nonunion treatment within a five-year period (2015-2019). Full-text clinical articles in the English language were selected for analysis only if they contained treatment results, complications and described large patient samples (not less than ten cases for congenital, post-tumor resection cases or rare conditions, and more than 20 cases for the rest). Case reports were excluded. RESULTS Fifty full-text articles and reviews on distraction osteogenesis were chosen. Thirty-five clinical studies containing large series of patients treated with this method and problems with its outcome were analyzed. It was found that distraction osteogenesis techniques provide treatment for segmental bone defects and nonunion of the lower extremity in many clinical situations, especially in complex problems. The Ilizarov techniques treat the triad of problems simultaneously (bone loss, soft-tissue loss and infection). Management of tibial defects mostly utilizes the Ilizarov circular fixator. Monolateral fixators are preferable in the femur. The use of a ring fixator is recommended in patients with an infected tibial bone gap of more than 6 cm. High rates of successful treatment were reported by the authors that ranged from 77% to 100% and depended on the pathology and the type of Ilizarov technique used. Hybrid fixation and autogenous grafting are the most applicable solutions to avoid after-frame regenerate fracture or deformity and docking site nonunion. CONCLUSION The role of Ilizarov non-free bone plasty has not lost its significance in the treatment of segmental bone defects despite the shortcomings and treatment problems encountered.

Abstract
OBJECTIVE To investigate the effectiveness of Masquelet technique combined with flap transplantation in treatment of infectious bone and soft tissue defects of the lower leg. METHODS Between January 2013 and January 2017, 35 cases of infectious bone and soft tissue defects of lower leg were treated with Masquelet technique combined with flap transplantation. There were 21 males and 14 females, with an average of 31.5 years (mean, 25-55 years). All patients were tibial fractures caused by trauma and the infections occurred after debridement or internal fixation. The time from injury to admission was 1 to 6 months, with an average of 3.2 months. Defect located at the proximal leg in 11 cases, the middle leg in 11 cases, and the distal leg in 13 cases. The length of tibia defect after debridement ranged from 5.6 to 11.2 cm, with an average of 7.1 cm. The size of soft tissue defect ranged from 14.2 cm×6.9 cm to 17.3 cm×8.7 cm. Bacterial culture of purulent secretion of wound was positive in 18 cases. After debridement, the bone cement was used to fill the bone defect and the flap transplantation was used to repair the wound. The bone cement was taken out at 8 to 12 weeks after the one-stage operation, and the bone defect was repaired with autogenous iliac bone or combined with artificial bone. RESULTS Three cases had necrosis at the distal edge of the flap after one-stage operation, and survived after dressing change. The other flaps survived successfully, and the wounds healed by first intention. All incisions healed by first intention after two-stage operation. All patients were followed up 24-32 months, with an average of 27 months. The color of the flap was similar to that of the surrounding normal tissue, and its texture was good. X-ray reexamination showed that all bone defects healed after 6-8 months, with an average of 6.7 months. At 9 months after two-stage operation, according to the revised Edwards tibial fracture evaluation standard, 19 cases were excellent, 14 cases were good, and 2 cases were poor, the excellent and good rate was 94.3%. The American Orthopedic Ankle Association (AOFAS) score was 60-98, with an average of 81.3. And 21 cases were excellent, 11 were good, and 3 were fair, with an excellent and good rate of 91.4%. CONCLUSION Masquelet technique combined with flap transplantation is an effective treatment for infectious bone and soft tissue defects of lower leg.

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
Aim The purpose of this study was to compare the functional and radiological outcomes of complex tibia fractures treated with two different hexapod fixators. Material and methods This is a retrospective comparative study of patients treated for complex tibial fractures between 2010 and 2015. Inclusion criteria was patients between 18 years and 60 years of age, who sustained a complex comminuted open or closed tibial fracture with or without bone loss, who had a minimum of 12 months’ follow-up, and who have been treated definitively using either Taylor Spatial Frame (TSF) or TrueLok-Hexapod System (TL-HEX). The outcome measures were Association for the Study and Application of the Method of Ilizarov (ASAMI) score, foot function index (FFI), EQ5-D, four-step square test (FSST), and timed up and go (TUG) test. Descriptive statistics were used to assess patient demographic information. Categorical variables (ASAMI and EQ5D-5L) were analysed using the χ2 test. Continuous variables (FFI, functional tests, and radiographic outcomes) were analysed with two-tailed Student’s t tests. Results In all, 24 patients were treated with the TL-HEX and 21 with the TSF. The mean time for external fixation was 219 ± 107 days (TL-HEX) and 222 ± 98 days (TSF). Union occurred in 92% (TL-HEX) and 100% (TSF). The mean follow-up was 777 ± 278 days (TL-HEX) and 1211 ± 388 days (TSF). Using the ASAMI scores, there were 17 excellent and 6 good results for the TL-HEX and 10 excellent and 11 good results for the TSF (p = 0.33). The FFI was 30 ± 28.7 (TL-HEX) and 26.1+23.9 (TSF) (p = 0.55). The EQ5D was 0.67 ± 0.3 (TL-HEX) and 0.73 ± 0.2 (TSF) (p = 0.43). The mean TUG and FSST were 9.2 ± 3.2 and 10 ± 2.9 seconds (TL-HEX) and 8.4 ± 2.3 and 9.6 ± 3.1 seconds (TSF) (p = 0.34 and 0.69). Conclusion The results of this study suggest that both hexapod external fixation devices have comparable clinical, functional, and radiographic outcomes. Either fixator can be used for the treatment of complex tibial fractures, anticipating good and excellent clinical outcomes in approximately 80% patients.

Preliminary results using patient-specific 3d printed models to improve preoperative planning for correction of post-traumatic tibial deformities with circular frames. Injury 2018; 49 Suppl 2:S51-S59. [PMID: 30219148 DOI: 10.1016/j.injury.2018.07.017] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2018] [Revised: 07/08/2018] [Accepted: 07/23/2018] [Indexed: 02/02/2023]
Abstract
BACKGROUND Preoperative planning for circular external fixators is considered vital towards achieving the best results for complex post-traumatic tibial deformities, and patient-specific 3D printed (3DP) models were used here as a planning aid. The main goal was to investigate the fidelity of the preoperative planning process, by assessing the potential to reduce operative time and determining the need to adjust pre-constructed frames intra-operatively. PATIENTS AND METHODS Nine patients (10 limbs) underwent treatment for post-traumatic tibial complications using circular external fixation. These were compared to 10 similar cases where a 3DPM was not used as a pre-operative planning aide (Control group). Patient-specific models of affected bones were printed, and preoperative planning was performed using conventional techniques and Hexapod-assisted software. Detailed planning in a virtual procedure determined osteotomy levels and identified sites for wires and half-pins. The prototype of the external fixator was locked in this optimized configuration, removed from the model, and sterilized prior to the actual procedure. RESULTS Nine patients with 10 limbs were treated for complications following tibial fractures. Seven were infected non-unions, and three cases were malunions. For all cases a CT based 3DP model of the full tibia was used in the preoperative planning stage. Image analysis required a mean of 1.7 h, with an average of 14.9 h to 3D print each model. In the control group (without a 3D model), the mean surgical time was 329 min (180-680). The mean surgical time in the 3DPM group was only 172.4 min (72-240), (p = 0.024), reducing the surgery time by 48%. For the 3DPM group it was not necessary to modify the preassembled frame in any case, while in the Control group, the pre-constructed frame required intra-operative modifications in 8 of the 10 cases (p = 0.0007). CONCLUSION Using patient-specific 3D models has allowed us to carry out meticulous preoperative planning sessions, eliminating the need to modify or alter the frame assembly in the operating room, saving substantial surgical time and enabling a more precise design of the apparatus. This was especially useful in multiplanar deformities and for the spatial configuration of the foot support, talus ring, and ankle ring.
