Orthop Traumatol Surg Res 2023; 109:103532. [PMID: 36572380 DOI: 10.1016/j.otsr.2022.103532] [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: 02/09/2022] [Revised: 08/05/2022] [Accepted: 09/27/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Humeral shaft non-union is frequent, with severe clinical impact. Management, however, is poorly codified and there is no clear decision-tree. HYPOTHESIS Analyzing our experience over the last 15years could enable a reproducible strategy to be drawn up, with a decision-tree based on the 2 main causes: failure of internal fixation, and infection. MATERIAL AND METHOD Sixty-one patients were included in a retrospective cohort, with a mean 94 months' follow-p. The treatment strategy was based on screening first for infection then for mechanical stability deficit in case of prior internal fixation. Any fixation revision was associated to cancellous autograft. In case of suspected or proven infection, 2-stage treatment was implemented. In case of primary non-operative treatment, the strategy was based on the non-union risk on the Non-Union Scoring System (NUSS), with internal fixation and possible graft. RESULTS There were 6 failures, for a consolidation rate of 90%; excluding patients not managed according to the study protocol, the consolidation rate was 95%. There was 1 case of spontaneously resolving postoperative radial palsy, and 3 patients required surgical revision. DISCUSSION The present strategy achieved consolidation in most cases, providing the surgeon with a decision-tree for these patients. Infectious etiologies are often overlooked and should be a focus of screening. LEVEL OF EVIDENCE IV, retrospective or historical series.

Abstract
INTRODUCTION Complications associated with the application of the Reamer-irrigator-Aspirator (RIA) system are described in the literature. However, to date a systematic review and meta-analysis to assess prevalence of complications associated with the use of the RIA system have not been conducted. MATERIALS AND METHODS The review is registered with PROSPERO (CRD42021269982). MEDLINE, the Web of Science Core Collection, and Embase were searched from the inception to 10 August 2021. The primary objective was to assess complications and blood loss associated with the use of the RIA system. RESULTS Forty-seven studies involving 1834 procedures performed with the RIA system were finally included. A total of 105 complications were reported, with a pooled estimated overall prevalence of 1.7% with a 95% confidence interval (CI) of 0.40 to 3.60, with cortex perforation being the largest reported complication with a total of 34 incidences. A significant subgroup difference was observed (p = 0.02). In subgroup 1 (bone graft harvesting), complication prevalence was 1.4% (95% CI 0.2-3.4); in subgroup 2 (clearance intramedullary canal) it was 0.7% (95% CI 0.00-6.30) and in subgroup 3 (reaming with RIA system prior to nail fixation) 11.9% (95% CI 1.80-26.40). No statistically significant difference for tibia and femur as RIA system application site was observed (CI 0.69-4.19). In studies reporting blood loss, a mean volume of 803.29 ml, a mean drop of hemoglobin of 3.74 g/dl and a necessity of blood transfusion in 9.72% of the patients were observed. CONCLUSIONS The systematic review and meta-analysis demonstrate a low overall prevalence rate of complications associated with the RIA system. However, especially the risk of cortical perforation and the frequently reported relevant intraoperative blood loss are complications that should be anticipated in perioperative management and ultimately considered when using the RIA system.

Filling the gap: a series of 3D-printed titanium truss cages for the management of large, lower limb bone defects in a developing country setting. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023; 33:497-505. [PMID: 36385681 DOI: 10.1007/s00590-022-03434-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 11/09/2022] [Indexed: 11/18/2022]
Abstract
INTRODUCTION Large segmental long bone defects are notoriously difficult to manage. Treatment is resource-intensive due to the complexity, cost, and specialized skills required. Truss designs are known for their triangular shapes organized in web configurations. This allows for maximal mechanical strength, the least mass, and a lattice that can be filled with bone graft. Using a truss cage combined with contemporary internal fixation provides immediate stability for bone ingrowth and long-term potential union. The implant is designed using virtual 3D modelling of the patient's bone defect based on a CT scan. The truss cage can be used in a staged procedure combined with Masquelet's induced membrane technique. This study aims to review the outcomes of patient-specific, locally designed 3D titanium truss cages packed with cancellous autograft in treating segmental, long bone defects in the lower limb in a developing country setting. METHODS This retrospective series reviewed cases performed at various institutions between January 2019 and March 2022. Parameters assessed included patient demographics, size and location of the defect, time to clinical and radiological union and complications. RESULTS Nine cases were included for review, with a mean age of 36 years (range 19-52). Defects ranged from 60 to 205 mm, and eight cases were staged procedures. Eight cases used intramedullary reamings as bone graft. Contemporary intramedullary nails were used for fixation in all cases. No peri- or post-operative complications occurred. All cases progressed to functional union. CONCLUSION 3D-printed titanium truss cages combined with bone graft appear to be an effective treatment of large bone defects in the lower limb in a developing country setting in the short term. No complications were encountered, but longer follow-up is needed before definitive recommendations can be made. LEVEL OF EVIDENCE Level IV (retrospective case series).

Abstract
PURPOSE Whilst recurrence and amputation rates in post-traumatic osteomyelitis (PTOM) are described, limb specific functional outcomes are not, leading to a knowledge gap when counselling patients prior to management. We aim to investigate the patient reported outcomes (PROMS) of this patient group to provide reference for discussions with patients prior to embarking on treatment. METHODS Single institution cross-sectional retrospective study of all patients presenting with PTOM of the tibia/femur over a 7-year period. Alongside recurrence and amputation rates, patient reported outcomes were recorded including the lower extremity functional scale (LEFS), EQ-5D-3L and EQ-VAS. RESULTS Seventy-two patients (59 male; median age 46 years) were identified. Treatment was principle-based and included debridement (with Reamer-Irrigator-Aspirator (RIA) in 31/72), local antibiotics (52/72), soft tissue reconstruction (21/72) and systemic antibiotic therapy in all cases. PROMS were collected in 84% of all eligible patients at a median of 112-month post-treatment. Twelve patients experienced recurrence, whilst nine underwent amputation. The median LEFS was 60, the EQ-5D-3L index score was 0.760, and the EQ-VAS was 80. These scores are substantially lower than those seen in the general population (77, 0.856 and 82.2, respectively). LEFS was significantly higher, where RIA was utilised (69.6 vs 52.8; p = 0.02), and in those classified as BACH uncomplicated (74.4 vs 58.4; p = 0.02). EQ-5D-3L was also higher when RIA was utilised (0.883 vs 0.604; p = 0.04), with no difference in EQ-VAS scores. CONCLUSIONS Patients with PTOM report functional outcomes below that of the general population, even when in remission. Improved outcomes were associated with uncomplicated disease and the use of RIA.

Abstract
Abstract
Purpose
The cost implications of limb reconstruction techniques have not been adequately investigated. Aim of this pilot study was to compare the direct medical cost of tibial bone defects managed with distraction osteogenesis–Ilizarov method (ILF), or with Masquelet technique (MIF).
Methods
Data of 20 random patients treated in a single centre were analysed. Inclusion criteria included acute tibial defects, or post-debridement of nonunions with complete follow-up and successful union. The endpoint of clinical efficacy was the time-to-defect union. Comparisons were made between equally sized subgroups (ILF vs. MIF).
Results
The average defect length was 5.6 cm (2.6–9.6 cm). The overall cost of 20 cases reached £452,974 (mean £22,339, range £13,459–£36,274). Statistically significant differences favoring the MIF were found regarding the average time-to-union; number of surgeries, of admissions and follow-up visits, as well as the mean intraoperative cost (£8857 vs. £14,087). These differences lead to significant differences of the mean cost of the overall treatment (MIF £18,131 vs. ILF £26,126). Power analysis based on these data indicated that 35 patients on each group would allow detection of a 25% difference, with an alpha value of 0.05 and probability (power) of 0.9.
Conclusions
The results and analysis presented highlight factors affecting the high financial burden, even in a best-case scenario, this type of surgery entails. Larger pivotal studies should follow to improve the cost efficiency of clinical practice.

Abstract
The first Trauma and Orthopaedic unit dates back to 1780, originally dedicated to the treatment of children's deformities. The specialty has subsequently become multifaceted, with a plethora of subspecialty areas of which orthopaedic trauma is the most commonly practiced. Recently there has been a significant demand for an evidence base with more than 130,000 of the 162,000 publications in the last century occurring within the past 20 years. This narrative review will summarise some of the more landmark changes within orthopaedic trauma that have been made within the past 20 years, whilst also attempting to predict where the specialty will continue to develop as we move forward.

Abstract
The Reamer-Irrigator-Aspirator (RIA-2) system has been established as a safe and reliable device to harvest large amounts of autograft. Nevertheless, hardware complications may occur. Breakage of the reamer head from the drive shaft with intramedullary retention of small metal debris has never been dealt with. The authors provide a technical trick as a bailout in this difficult situation.

Abstract
Recently, reamer-irrigator-aspirator (RIA) systems have been increasingly used to harvest autologous bone grafts. RIA graft materials contain bone marrow, which provides a viable source to derive large numbers of mesenchymal stem cells. Low-intensity pulsed ultrasound (LIPUS) significantly accelerates the differentiation of stem cells derived from bone marrow. This in vitro study investigated the effect of LIPUS on the osteogenic activity and differentiation of RIA graft-derived cells. A small amount of RIA graft was obtained from seven patients. After the cells derived from RIA grafts were cultured, they were divided into two groups: the LIPUS and control groups. LIPUS was applied once daily for 20 min (1.5 MHz, pulse duration: 200 µs, pulse repetition rate: 1 kHz, spatial average-temporal average intensity: 30 mW/cm2). Alkaline phosphatase activity (113.4% and 130.1% on days 7 and 14), expression of osteoblast-related genes (ALP, Runx2) and mineralization (135.2% on day 21) of the RIA graft-derived cells were significantly higher in the LIPUS group than in the control group. However, LIPUS did not affect the cell proliferation of RIA graft-derived cells. This study indicates that LIPUS may enhance the healing of non-union and critical bone defects treated by autologous bone grafting using the RIA system.

Patient Saf Surg 2022; 16:2.

Abstract
Background The Reamer–Irrigator–Aspirator system was initially developed to reduce fat embolism and thermic necrosis during reamed intramedullary nail fixation of femoral shaft fractures. Currently, this system is used in extended applications including accessing large volume of autologous bone graft, as alternative for iliac crest harvesting. Antegrade femoral bone graft harvesting using the Reamer-Irrigator-Aspirator system is considered the standard technique. The aim of our study is to evaluate the efficacy (bone graft volume) and the complications (blood loss, postoperative pain, and incidence of iatrogenic fractures) of the Reamer–Irrigator–Aspirator system through the retrograde femoral route in a series of patients with post-traumatic bone defects or nonunions. Methods A non-controlled single center retrospective observational cohort study was conducted in a level1 trauma center to evaluate all patients who were treated using the RIA system. Between November 2015 and May 2019, 24 patients (8 women and 16 men; mean age: 41 years [range 27–55 years]) with bone defects or nonunions underwent bone graft harvesting using the Reamer–Irrigator–Aspirator system through retrograde femoral route. Postoperative pain, complications, and bone graft volume were analyzed. Inclusion criteria was patients older than 18 years with a diagnosis of post-traumatic bone defect or associated tibial or femoral nonunion, with minimum 6-months follow, treated using the RIA. We hypothesized that the retrograde route of the RIA system is a safe and efficacious method for bone harvesting. Results The average volume of collected graft was 45 cc (range 30–60 cc). In 83% of the cases, bone grafting was sufficient, while in 17% it was necessary to add iliac crest bone graft to completely fill the bone defect. A mean drop in postoperative hemoglobin of 4.1 g / dL (range 0.5–6.0 g / dL) was evidenced. In 4 cases (33%), a unit of packed red blood cells was required. Regarding postoperative pain, visual analogue scale after 3 months postoperatively was 1.6 in average. After 6 months, the value has decreased to 0.4. There were no perioperative or postoperative complications at 6-month follow-up. Conclusion In this limited case series, large volumes of bone graft were harvested using the retrograde route of the RIA system and there were no intra-/ postoperative complications observed at 6-month follow-up. Therefore this novel technique appears safe and efficacious. However, it’s important to highlight that future prospective controlled studies are necessary to validate the insights from this pilot study.

Abstract
Femoral shaft nonunions are disabling complications of fractures, with relevant socioeconomic and psychological impact. The incidence of femoral shaft nonunions is not negligible, ranging between 1% and 10% after intramedullary nailing, but can exceed 20% in case of subtrochanteric fractures. Treatment options are influenced by pathomechanical, anatomical, and clinical factors. Hypertrophic nonunions are usually treated by enhancing stability of fixation, while atrophic nonunions require additional biological stimulation to achieve bone union. The Reamer-Irrigator-Aspirator (RIA) System® was developed to reduce intramedullary pressure and heat generation during intramedullary reaming, thus preventing thermal necrosis and decreasing the risk of fat embolism. The RIA System allows to provide large volumes of high-quality morselized autologous bone, that has shown high osteogenetic and osteoinductive properties. Therefore, its use has been expanded as a valuable source of autologous bone graft for the treatment of large bone defects of different nature. In this article, we present two cases of complex femoral nonunions treated with the use of the RIA System. A review of the published literature on the treatment of femoral nonunions with RIA was also performed. Core tip: In case of atrophic nonunions, the RIA System can be used to obtain biologically active tissue to enhance bone healing. Despite the absence of high-quality studies focused on femoral nonunions, the efficacy of RIA is well-known and orthopaedic surgeons should be aware of this powerful tool.

Abstract
BACKGROUND The reamer irrigator aspirator (RIA) is a relatively recent device that is placed in the medullary canal of long bones to harvest a large volume of bone marrow, which is collected in a filtered canister. This study compares outcomes and complications of the RIA versus a traditional iliac crest bone graft (ICBG) for the treatment of bone defects. METHODS This meta-analysis was conducted according to the PRISMA guidelines. The Embase, Google Scholar, PubMed, and Scopus databases were accessed in June 2021. All clinical trials comparing the RIA and ICBG with a minimum of 6 months follow-up were included. RESULTS Data from 4819 patients were collected. The RIA group demonstrated lower site pain (P < 0.0001), fewer infections (P = 0.001), and a lower rate of adverse events (P < 0.0001). The ICBG group demonstrated a greater rate of bone union (P < 0.0001). There was no difference between groups in VAS (P = 0.09) and mean time to union (P = 0.06). CONCLUSION The current evidence supports the use of the RIA, given its low morbidity and short learning curve.

Abstract
Autologous bone grafting is common in trauma and orthopaedic surgery. Both the Reamer Irrigator Aspirator (RIA) and Iliac Crest Bone Graft (ICBG) aim to obtain autologous bone graft. Although the process of harvesting a bone graft is considered simple, complications may occur. This study examined morbidity and pain at the donor site, blood loss, and iatrogenic fractures, comparing RIA and ICBG. The source of the autologous bone graft, the alternative graft sites, and the storage modalities of the harvested bone marrow were also evaluated. In May 2021, PubMed, Embase, Scopus, and Google Scholar were accessed, with no time constraints. RIA may produce greater blood loss, but with less morbidity and complications, making it a potential alternative source of bone grafting.

Abstract
Biofilm represents an organized multicellular community of bacteria having a complex 3D structure, formed by bacterial cells and their self-produced extracellular matrix. It usually attaches to any foreign body or fixation implant. It acts as a physical protective barrier of the bacteria from the penetration of antibodies, bacteriophages, granulocytes and biocides, antiseptics, and antibiotics. Biofilm-related infections will increase in the near future. This group of surgical site infections is the most difficult to diagnose, to suppress, to eradicate, and in general to manage. Multispecialty teams involved in all stages of care are an effective way to improve results and save resources and time for the benefit of patients and the health system. Significant steps have occurred recently in the prevention and development of clever tools that we can employ in this everlasting fight with the bacteria. Herein, we attempt to describe the nature and role of the "biofilm" to the specific clinical setting of surgical site infections in the field of orthopaedic trauma surgery.

Abstract
OBJECTIVE The aim of this study was to retrospectively analyze the experience of treating long segmental bone defects. Bone union was used as the criteria for the assessment of the quantitative relationship between tibial bone defects and bone grafts, which could help reduce the complication incidence in patients. METHODS A total of 45 patients with tibial bone defects treated with the Masquelet technique at the Ninth People's Hospital of Wuxi Affiliated to Soochow University between February 2013 and December 2017 were recruited. The age, sex, body mass index (BMI), complications, site of bone defect, length of bone defect, time from the first to the second stage of operation, and postoperative complications (including deep infection, absorption of bone graft, and bone union) were assessed. RESULTS Forty-two patients, including 17 males (40.5%) and 25 females (59.5%), with segmental bone defect, met the inclusion criteria. The mean age of the patients was 38.5 years (22-55 years). Nineteen patients (45.2%) underwent multiple traumas. The mean length of the bone defect was 6.3 cm. Six patients experienced complications, resulting in the incidence of complications of 14.3%. The relationship between the length of bone defect and volume of bone grafts was Y = 7.210 + 6.954 × X in patients treated with steel plates; Y = 10.962 + 5.029 × X for patients treated with intramedullary nails, and Y = 11.498 + 5.474 × X regardless of methods of internal fixation. CONCLUSION Masquelet technique is effective and safe for the treatment of long segmental tibial bone defects. The present study revealed the quantitative relationship between the size of bone defects and bone grafts, thus providing evidence for the selection of treatment strategies for long segmental bone defects in clinical practices, as well as helping to reduce the incidence of complications in Masquelet technique.

Abstract
Nonunions represent a very heterogeneous, rare and sometimes very complex disease picture. The causes, localization and degree of expression show a very high variability, which makes it difficult to establish uniform treatment standards. Nevertheless, the process of bone healing is subject to some essential factors, which should be ensured for a successful treatment. Over the years these factors have been better researched and were taken into consideration for the diamond concept, which was first published by Giannoudis et al. in 2007. This provides the physician with a concept that does not neglect the heterogeneity of the disease picture and is an aid to decision making for the treatment regimen in individual cases in order to guarantee the best biological and mechanical conditions. The diamond concept is nowadays widely used and many studies have already demonstrated a successful application. It must be understood as a framework, in which the various treatment options available (bone substitute materials, mesenchymal stem cells, osteosynthesis procedures etc.) are incorporated into the individual factors and therefore provides the physician with a certain freedom of choice in the selection of tools. Additionally, it is not a rigid corset and subject to medical scientific progress in its factors, so that it is exciting to see which new developments will be incorporated in the future.

Abstract
Fracture-related infection (FRI) remains a challenging complication that imposes a heavy burden on orthopaedic trauma patients. The surgical management eradicates the local infectious focus and if necessary facilitates bone healing. Treatment success is associated with debridement of all dead and poorly vascularized tissue. However, debridement is often associated with the formation of a dead space, which provides an ideal environment for bacteria and is a potential site for recurrent infection. Dead space management is therefore of critical importance. For this reason, the use of locally delivered antimicrobials has gained attention not only for local antimicrobial activity but also for dead space management. Local antimicrobial therapy has been widely studied in periprosthetic joint infection, without addressing the specific problems of FRI. Furthermore, the literature presents a wide array of methods and guidelines with respect to the use of local antimicrobials. The present review describes the scientific evidence related to dead space management with a focus on the currently available local antimicrobial strategies in the management of FRI. LEVEL OF EVIDENCE:: Therapeutic Level V. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Introduction The treatment of chronic intramedullary infection of the long bones relies on microbe-specific antibiotics in conjunction with surgical removal of infected necrotic material. We discuss the use of reamer–irrigator–aspirator(RIA) for debridement of the intramedullary canal instead of conventional reaming techniques. This is the first case report to explore the use of RIA for osteomyelitis. Case Report We discuss the use of the RIA in treatment of a 26-year-old female presenting with chronic osteomyelitis of the left distal femoral shaft. She had normalization of infection laboratories at 6 weeks and complete resolution of symptoms at 3 months and was released at 6 months. Conclusion Recent exploration of the RIA system’s (Synthes®, Inc. West Chester, Philadelphia) multipurpose applications has indicated use in long bone debridement. While further exploration and high-quality studies are needed to make robust claims of efficacy, we believe that the use of RIA in the context of chronic osteomyelitis is a superior alternative to conventional reaming techniques.

Abstract
Autologous bone graft remains the only clinically available source of graft material with osteogenic, osteoinductive, and osteoconductive properties. Although iliac crest autologous bone graft has long served as the benchmark, reamed autogenous bone graft offers several advantages. Reamed autograft has a biochemical and cellular profile that is at least equivalent, and perhaps superior, to that of iliac crest autograft. In addition, larger volumes of reamed autograft can be obtained via less-invasive techniques, giving surgeons an accessible source of mesenchymal stem cells that can be reliably and repeatedly harvested. Early clinical experience involving reamed autogenous bone graft in the management of nonunion, bone defects, and arthrodesis has been encouraging and has demonstrated the necessary properties to warrant regular consideration of reamed graft for these applications.

Abstract
BACKGROUND Autologous bone grafting (ABG) remains the gold standard for augmentation of bone defects. The RIA system has become more prevalent, but evidence regarding risk management and complications remain scarce. This study presents the risk management and complications associated with RIA in the largest single-center case series to date. METHODS All records, operative notes, lab data and radiographs of patients receiving a RIA procedure at Heidelberg´s University Hospital between 01/01/2010 and 31/12/2016 were reviewed. Multivariate logistic regression models adjusting for clinically relevant covariates were used to examine the respective relevance regarding the presence and absence of prolonged postoperative pain (PPP). RESULTS A total of 341 RIA procedures on 306 patients were performed at our level-1 trauma center. The femur was the main donor site (98.53%; N = 336) whereas only in 1.47% (N = 5) the tibia was utilized. A total of 11 patients showed a relevant loss of hemoglobin requiring blood transfusion. A total of 22 patients suffered from PPP directly associated with the RIA procedure resulting in prevalence of 6.45%. The 6 major complications in our study were of diverse origin and all intraoperative complications took place in the early phase of the RIA procedure in our center (2010-2013). Our data revealed influence of sex (p = 0.0459) and age (p = 0.0596) on the criterion PPP. The favored model including sex and age resulted in an AUC of 66.2% (CI: 55.5%-76.9%). CONCLUSION Perioperative blood loss remains a prevalent complication during RIA reaming. In addition, PPP occurs with a prevalence of 6.45%. This study showed a complication rate of 1.76%, emphasizing RIA´s overall safety and furthermore highlighting the need for vigilance in its application and prior extensive hands-on training of surgeons.

Abstract
While the RIA system was initially designed for reaming and clearing the femoral canal contents in preparation for femoral nailing, it has since been used in various other applications in the field of orthopaedic surgery. The RIA is an ideal device for accessing large quantities of autogenous bone graft, to be used in the treatment of nonunions, segmental bone loss, or arthrodesis. The RIA has also been used for treatment of intramedullary infections and osteomyelitis, as well as intramedullary nailing of long bones with metastatic lesions, as it allows for clearing the canal of infectious/tumour burden, and lowers the risk of dissemination into the soft tissues and systemic circulation. There is also some limited evidence that the RIA may be used for clearing the femoral/tibial canal of cement debris. Despite multiple applications, the use of RIA has a risk of eccentric reaming and iatrogenic fractures. RIA is also a costly procedure, and its routine use may not be advantageous in the setting of limited health care resources.

Abstract
OBJECTIVES To investigate the blood loss and transfusion rate associated with the use of reamer irrigator aspirator (RIA). DESIGN Retrospective review. SETTING Academic Level-I trauma hospital. PATIENTS One hundred eight patients requiring bone graft harvest for surgical reconstruction of nonunion or failed arthrodesis. INTERVENTION Bone graft harvest preformed via RIA or iliac crest bone graft (ICBG). MAIN OUTCOME MEASURE Blood loss as measured by a change in preoperative and postoperative hematocrit (Hct). In addition, postoperative transfusion reported intraoperative blood loss, volume of graft harvested, and major complications. RESULTS The average Hct drop was found to be 13.7 (4.1-27.4) in the RIA cohort of 61 patients and 7.36 (1.2-14.5) in the ICBG cohort of 47 patients (P = 0.013). Operative reports documented an average estimated blood loss of 674 mL (100-2000 mL) in the RIA cohort compared with 255 mL (50-1000 mL) in the ICBG cohort (P < 0.001). Twenty-seven patients (44%) required blood transfusion after RIA, whereas 10 patients (21%) required blood transfusion after ICBG (odds ratio 5.32, 95% confidence interval 2.2-6.3, P < 0.001). RIA procedures collected an average 53 mL (20-100 mL) of bone graft compared with 27 mL (15-50 mL) with ICBG. There was no significant difference between groups regarding age, sex, medical comorbidities, or postoperative major complications. CONCLUSIONS This series demonstrated that 44% of patients undergoing RIA bone graft harvest required transfusion, with a mean Hct drop of 13.7 across all subjects, which is significantly greater than that associated with ICBG. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Antibiotic cement nails provide a useful and relatively simple technique to treat intramedullary osteomyelitis of the long bones. These devices provide stability as well as local, targeted antibiotics, which are both critical aspects of osteomyelitis management. Additionally, the use of a threaded core is a critical component of successful cement nail assembly. With adherence to the simple principles outlined in this review, surgeons can expect reliably good results using these drug-delivery implants.

Abstract
Infected nonunions of tibia pose many challenges to the treating surgeon and the patient. Challenges include recalcitrant infection, complex deformities, sclerotic bone ends, large bone gaps, shortening, and joint stiffness. They are easy to diagnose and difficult to treat. The ASAMI classification helps decide treatment. The nonunion severity score proposed by Calori measures many parameters to give a prognosis. The infection severity score uses simple clinical signs to grade severity of infection. This determines number of surgeries and allows choice of hardware, either external or internal for definitive treatment. Co-morbid factors such as smoking, diabetes, nonsteroidal anti-inflammatory drug use, and hypovitaminosis D influence the choice and duration of treatment. Thorough debridement is the mainstay of treatment. Removal of all necrotic bone and soft tissue is needed. Care is exercised in shaping bone ends. Internal fixation can help achieve union if infection was mild. Severe infections need external fixation use in a second stage. Compression at nonunion site achieves union. It can be combined with a corticotomy lengthening at a distant site for equalization. Soft tissue deficit has to be covered by flaps, either local or microvascular. Bone gaps are best filled with the reliable technique of bone transport. Regenerate bone may be formed proximally, distally, or at both sites. Acute compression can fill bone gaps and may need a fibular resection. Gradual reduction of bone gap happens with bone transport, without need for fibulectomy. When bone ends dock, union may be achieved by vertical or horizontal compression. Biological stimulus from iliac crest bone grafts, bone marrow aspirate injections, and platelet concentrates hasten union. Bone graft substitutes add volume to graft and help fill defects. Addition of rh-BMP-7 may help in healing albeit at a much higher cost. Regeneration may need stimulation and augmentation. Induced membrane technique is an alternative to bone transport to fill gaps. It needs large amounts of bone graft from iliac crest or femoral canal. This is an expensive method physiologically and economically. Infection can resorb the graft and cause failure of treatment. It can be done in select cases after thorough eradication of infection. Patience and perseverance are needed for successful resolution of infection and achieving union.

Abstract
The management of upper limb non-unions can be challenging and often with unpredictable outcomes. In this study we present our experience with the use of BMP-7 in the treatment of upper limb non-unions. Between 2004 and 2011 all consecutive patients who were treated with BMP-7 were followed up prospectively until fracture union. Fracture union was assessed with regular radiological and clinical assessment. At the final follow up clinical assessment included the short Disabilities of the Arm, Shoulder and Hand (DASH) score. The minimum follow up was 12 months (12-36). In total 42 patients met the inclusion criteria with a mean age of 47 years. Anatomical distribution of the nonunion sites included 19 cases of mid/proximal forearm, 14 humeri, 6 distal radius and 3 clavicle. 35 patients had atrophic non-union, 11 had previous open fractures, and 10 had bone loss (range 1-3 cm). The mean number of operations performed and the mean time from injury to BMP-7 application was 1.5 and 26 months, respectively. 40 fractures had both clinical and radiological union whereas 2 patients had partial radiological union but a pain free range of motion. BMP-7 was applied in isolation in 1 case and in 41 cases the application was combined with autologous bone grafting. DASH scores were available at final follow up in 23 (55%) patients with a mean of 33 score (range 2-86.4). This study supports the view that the combination of ABG and BMP-7 can be considered as a successful treatment modality for the treatment of recalcitrant upper limb non-unions. Further studies preferably randomised controlled trials are desirable to throw more light into the role of BMP-7 in the treatment of upper limb nonunions.

Abstract
Purpose Reamer–irrigator–aspirator (RIA) is an innovative device that its indications have recently been expanded to the management of long bone infections. Methods In this narrative review, we summarise the most important studies in the field and we present the current open questions pertaining to the use of RIA in the management of osteomyelitis of long bones. Results The relevant literature is sparse and low quality. Nevertheless, the use of RIA for infected cases has yielded promising outcomes in specialised centres. Technical aspects that merit special attention in osteomyelitis of long bones are its inapplicability in small diameter long bones, the inadequate debridement of wide metaphyseal areas and the potential bleeding sequelae. The use of RIA in open fracture management to reduce infection risk has not gained acceptance. The antibiotic impregnated nails and rods constitute a complimentary strategy for the management of infections. Conclusions The use of RIA for the management of long bone infections is an innovative and promising strategy. High quality studies are needed to shed light in its efficacy compared to conventional methods of management of osteomyelitis of long bones.

Abstract
PURPOSE To explore the possible surgical factors related with nonunion in femoral shaft fracture following intramedullary nailing. METHODS We retrospectively analyzed totally 425 patients with femoral shaft fracture in level I urban trauma center, including 254 males and 171 females, with an average age of 37.6 (ranging from 21 to 56) years old. The inclusion criteria included: (1) traumatically closed fracture of femoral shaft, with pre- operative films showing non-comminuted fracture, such as transverse fracture, oblique fracture or spiral fracture; (2) closed reduction and fixation with interlocking intramedullary nail at 3-7 days after trauma; (3) complete follow-up data available. The relationship between the following factors (fracture site, reduction degree, direction of nail insertion and nail size) and nonunion was studied. RESULTS The incidence of femoral nonunion was 2.8% in patients with closed simple fracture undergoing interlocking intrameduallary nailing, including 11 cases of hypertrophic nonunion. Nonunion was related significantly to distal fracture, unsatisfactory reduction and unreamed nail (p < 0.05). There was no significant difference between antegrade nail and retrograde nail (p > 0.05). CONCLUSIONS Nonunion in femoral shaft facture following interlocking intramedullary nailing is related to fracture site, fracture reduction and nail diameter. The choice of reamed nails or unreamed nails depends on the fracture site and reduction degree.

Abstract
Since the first description in 2002 by Paley and Herzenberg, antibiotic bone cement nails (ACNs) have become an effective tool in the orthopaedic trauma surgeons' hands. They simultaneously elute high amounts of antibiotics into medullary canal dead space and provide limited stability to the debrided long bone. In this paper, we perform a systematic review of current evidence on ACNs in orthopaedic trauma and provide an up-to-date review of the indications, operative technique, failure mechanisms, complications, outcomes, and outlooks for the ACNs use in long bone infection.

Abstract
The management of malignant pathological fractures necessitates careful diagnostic work-up, pre-operative investigation, planning and multidisciplinary input from specialists in the fields of radiology, pathology, oncology, trauma and orthopaedics. Malignant and non-malignant conditions including metabolic disorders, benign tumours and pharmacological therapies can be implicated. The majority of patients who present with suspected pathological fractures will be managed by general orthopaedic and trauma surgeons rather than specialists in orthopaedic oncology. Skeletal metastases can result in considerable morbidity and predispose to pathological fractures. With advances in the medical management of malignancy, life expectancy in cancer patients is increasing, leading to an increasing risk of skeletal metastasis and the potential for pathological fractures. Conventional modes of trauma fixation for pathological fractures may not be appropriate. The aim of this review is to outline diagnostic and management strategies for patients who present with a long bone fracture that is potentially pathological in nature.

Abstract
Bone is one of the most dynamic tissues in the human body that can heal following injury without leaving a scar. However, in instances of extensive bone loss, this intrinsic capacity of bone to heal may not be sufficient and external intervention becomes necessary. Several techniques are available to address this problem, including autogenous bone grafts and allografts. However, all these techniques have their own limitations. An alternative method is the technique of distraction osteogenesis, where gradual and controlled distraction of two bony segments after osteotomy leads to induction of new bone formation. Although distraction osteogenesis usually gives satisfactory results, its major limitation is the prolonged duration of time required before the external fixator is removed, which may lead to numerous complications. Numerous methods to accelerate bone formation in the context of distraction osteogenesis have been reported. A viable alternative to autogenous bone grafts for a source of osteogenic cells is mesenchymal stem cells from bone marrow. However, there are certain problems with bone marrow aspirate. Hence, scientists have investigated other sources for mesenchymal stem cells, specifically adipose tissue, which has been shown to be an excellent source of mesenchymal stem cells. In this paper, the potential use of adipose stem cells to stimulate bone formation is discussed.

Abstract
INTRODUCTION Donor-site morbidity, complications and availability remain concerns in autologous bone grafting today. The Reamer/Irrigator/Aspirator system (RIA) provides an alternative method to overcome these problems. According to literature, RIA graft possesses a higher osteogenic potency. This study compares iliac crest and RIA graft performance by determining their in vitro osteogenic capacity in a porcine model. METHODS Osteogenic capacity and cell content was determined in RIA and iliac crest bone grafts harvested from six female domestic white pigs. Cells initially washed off, and cells harvested with collagenase were analysed separately and in combination. Alkaline phosphatase expression (ALP) and cell numbers were evaluated after 7 and 14 days of culture. Matrix mineralisation was quantified after 14 days. RESULTS Cell cultures showed a significant increase of matrix mineralisation by RIA-derived cells compared to iliac crest bone graft (p = 0.0313). The yield of collagenase derived cells was increased in the RIA group and a synergy between washed off and collagenase derived cells was observed. Cell proliferation was similar in both groups. DISCUSSION The osteogenic differentiation capacity of cell populations isolated from the RIA derived bone graft surpasses that of iliac crest derived cells. It is proposed that the observed effect can be attributed to the origin of the cells and to the specific action of the RIA system. This study provides further evidence indicating that RIA bone graft provides superior osteogenic properties compared to iliac crest bone graft.

Abstract
INTRODUCTION Clinical management of non-union of long bone fractures and segmental bone defect is a challenge for orthopaedic surgeons. The use of autologous bone graft (ABG) is always considered the gold standard treatment. Traditional techniques for harvesting ABG from iliac crest usually involve several complications, particularly at the donor site. The Reamer-Irrigator-Aspirator (RIA) is an intramedullary reaming system that generates a large volume of cancellous bone material in a single-step reaming process; this bone material can be collected and potentially used as an ABG source. Our interest is to compare the complications associated with the standard technique of harvesting from iliac crest with those of the innovative RIA harvesting device. MATERIALS AND METHODS A database of 70 patients with long bone non-unions was studied. The patients were divided into two groups according to the surgical harvesting technique used: RIA system ABG (35 patients) and iliac crest ABG (35 patients). RESULTS At the 12-month follow-up, pain at the donor site was reported in no patients in the RIA system ABG group and five of 35 patients (14.28%) in the iliac crest ABG group. Local infections at the donor site were found in no patients in the RIA system ABG group compared with five patients (14.28%) in the iliac crest ABG group. There were no fractures in the RIA system ABG group and one case (2.85%) of anterior superior iliac spine (ASIS) dislocation in the iliac crest ABG group. No systemic infections were detected in either group. DISCUSSION We analysed the scientific literature on the use of RIA technique to collect ABG for use in patients with anthropic-oligotrophic non-unions, with a focus on the complications associated with this technique. CONCLUSION RIA bone graft for the treatment of non-unions and segmental bone defect of long bones seems to be a safe and efficient procedure with low donor site morbidity.

Abstract
Intramedullary infection in long bones represents a complex clinical challenge, with an increasing incidence due to the increasing use of intramedullary fixation. We report a prospective case series using an intramedullary reaming device, the Reamer–Irrigator–Aspirator (RIA) system, in association with antibiotic cement rods for the treatment of lower limb long bone infections. A total of 24 such patients, 16 men and eight women, with a mean age of 44.5 years (17 to 75), 14 with femoral and 10 with tibial infection, were treated in a staged manner over a period of 2.5 years in a single referral centre. Of these, 21 patients had had previous surgery, usually for fixation of a fracture (seven had sustained an open fracture originally and one had undergone fasciotomies). According to the Cierny–Mader classification system, 18 patients were classified as type 1A, four as 3A (discharging sinus tract), one as type 4A and one as type 1B. Staphylococcus species were isolated in 20 patients (83.3%). Local antibiotic delivery was used in the form of impregnated cement rods in 23 patients. These were removed at a mean of 2.6 months (1 to 5). Pathogen-specific antibiotics were administered systemically for a mean of six weeks (3 to 18). At a mean follow-up of 21 months (8 to 36), 23 patients (96%) had no evidence of recurrent infection. One underwent a planned trans-tibial amputation two weeks post-operatively due to peripheral vascular disease and chronic recalcitrant osteomyelitis of the tibia and foot. The combination of RIA reaming, the administration of systemic pathogen-specific antibiotics and local delivery using impregnated cement rods proved to be a safe and efficient form of treatment in these patients.

Abstract
When performing fusions of the first metatarsophalangeal joint, it has been hypothesized that the use of a cup and cone reamer may cause thermal necrosis, leading to potential nonunion. The friction created by the reamer spinning against the bone has been shown to cause elevations of temperatures capable of causing thermal necrosis. Failing to cool the bony-reamer interface, or doing so inadequately with a bulb syringe, increases the patient's odds of experiencing a nonunion. The authors describe a simple technique that prevents significant temperature elevations at the reamer-bony interface, decreasing the potential for thermal necrosis and increasing the likelihood of successful fusion. The authors have performed this procedure for several patients without complications.

Abstract
The role of Bone Tissue Engineering in the field of Regenerative Medicine has been the topic of substantial research over the past two decades. Technological advances have improved orthopaedic implants and surgical techniques for bone reconstruction. However, improvements in surgical techniques to reconstruct bone have been limited by the paucity of autologous materials available and donor site morbidity. Recent advances in the development of biomaterials have provided attractive alternatives to bone grafting expanding the surgical options for restoring the form and function of injured bone. Specifically, novel bioactive (second generation) biomaterials have been developed that are characterised by controlled action and reaction to the host tissue environment, whilst exhibiting controlled chemical breakdown and resorption with an ultimate replacement by regenerating tissue. Future generations of biomaterials (third generation) are designed to be not only osteoconductive but also osteoinductive, i.e. to stimulate regeneration of host tissues by combining tissue engineering and in situ tissue regeneration methods with a focus on novel applications. These techniques will lead to novel possibilities for tissue regeneration and repair. At present, tissue engineered constructs that may find future use as bone grafts for complex skeletal defects, whether from post-traumatic, degenerative, neoplastic or congenital/developmental "origin" require osseous reconstruction to ensure structural and functional integrity. Engineering functional bone using combinations of cells, scaffolds and bioactive factors is a promising strategy and a particular feature for future development in the area of hybrid materials which are able to exhibit suitable biomimetic and mechanical properties. This review will discuss the state of the art in this field and what we can expect from future generations of bone regeneration concepts.

Abstract
BACKGROUND Subtrochanteric femoral non-unions in the setting of failed metalwork pose a challenging clinical problem. This study assessed the clinical outcome of patients treated according to the principles of the "Diamond" concept. METHODS Between 2007 and 2011 all patients presented with a subtrochanteric atrophic aseptic non-union in the setting of metalwork failure (broken cephalomedullary reconstruction nail), and treated in a single tertiary referral unit were included to this study. The hypertrophic and the non-unions of pathologic fractures were excluded. The revision strategy was based on the "Diamond concept"; optimisation of the mechanical and the biological environment (implantation of growth factor (rhBMP-7), scaffold (RIA bone graft from contralateral femur) and concentrated mesenchymal stem cells (MSCs) harvested from the iliac crest). The minimum follow up was 26 months (16-48). RESULTS Fourteen patients met the inclusion criteria. A specific sequence of metalwork failure was noted with initial breakage of the distal locking screws followed by nail breakage at the lag screw level. The intraoperative examination of the removed nails revealed no gross structural damage indicative of inappropriate drilling at the time of the initial intramedullary nailing. Varus mal-alignment was present in the majority of the cases, with an average of 5.2 degrees (0-11). The average time to distal locking screw failure was 4.4 months (2-8.5) and nail failure was 6.5 months (4-10). The time to union after the revision surgery was 6.8 months (5-12). Complications included two deaths in elderly patients (due to unrelated causes), one pulmonary embolism, one myocardial infarction, one below the knee deep vein thrombosis and one blade plate failure that required further revision with double plating and grafting. CONCLUSION Varus mal-alignment must be avoided in the initial stabilisation of subtrochanteric fractures. Distal locking screw failure is predictive of future fracture non-union and nail breakage. In the absence of sepsis, a single stage procedure based on the "Diamond concept" that simultaneously optimizes the mechanical and biological environment is a successful method for managing complex subtrochanteric atrophic non-unions with failed metalwork.

Abstract
AIM To compare the safety and effect on tibial diaphyseal fracture bone union of two intramedullary nailing techniques: (1) dynamic locking with early, full weight bearing, and (2) static locking with delayed weight bearing until bone union. PATIENTS AND METHODS This is a retrospective case-control study of closed or type I open tibial diaphyseal fractures (types A and B according to the AO classification) treated with dynamic nailing (32 cases) or static nailing (35 cases). The type of intramedullary nail, the surgical technique and the postoperative protocol were similar for both groups, with the exception of the locking mode and the time of weight bearing. Time to union, mechanical and biological complications, and the number and type of re-operations needed until union were recorded and analysed. RESULTS Mean union time was 21 weeks in the dynamic group and 26 in the static group (p = 0.051). In both groups 3 cases of nonunion were noted. In the dynamic group there was 1 case of delayed union and 1 case of malunion. In the static group, 5 cases of delayed union and 5 cases of malunion were found. Four reoperations were required in the dynamic group, whereas 10 were needed in the static group (p >0.05). Initial degree of interfragmentary gaps had an impact on the mean time to union and the appearance of biological complications in both groups. CONCLUSION Dynamic nailing assembly in intramedullary nailing in closed or type I open tibial diaphyseal fractures with limited comminution (types A and B according to the AO classification) is safe when used for these fracture types. A dynamic mode of nailing should be encouraged in these fracture patterns.

Abstract
The operative therapy management of vertebral osteomyelitis including debridement and stabilization is well established. Autologous bone is the preferred graft material but is limited due to availability, failure of consolidation in large defects and donor morbidity. Titanium mesh cages are alternatively equally well evaluated and other materials are also mentioned. Immobilization of affected segments is the fundamental requirement for healing of osteomyelitis. The operative therapy of choice is meticulous debridement and internal stabilization of the defect. Autologous bone seems to provide the best conditions to bridge and consolidate defects. Bone marrow aspirate, reaming irrigator aspiration (RIA) and bone marrow protein (BMP) in combination with cages have the same qualities considering bone healing but they are not yet sufficiently evaluated for management of vertebral osteomyelitis. Autologous bone graft remains the gold standard, nevertheless, its disadvantages point out the need for alternative grafts. Titanium is well proven to provide stability but bone substitutes are not sufficiently evaluated but seem to be promising.
