Abstract
Trauma is a leading cause of death in the United States for people under 45. Amongst trauma-related injuries, orthopedic injuries represent a significant component of trauma-related morbidity. In addition to the potential morbidity and mortality secondary to the specific traumatic injury or injuries sustained, sepsis is a significant cause of morbidity and mortality in trauma patients as well, and infection related to orthopedic trauma can be especially devastating. Therefore, infection prevention and early recognition of infections is crucial to lowering morbidity and mortality in trauma. Risk factors for fracture-related infection include obesity, tobacco use, open fracture, and need for flap coverage, as well as fracture of the tibia and the degree of contamination. Timely administration of prophylactic antibiotics for patients presenting with open fractures has been shown to decrease the risk of fracture-related infection, and in patients that do experience sepsis from an orthopedic injury, prompt source control is critical, which may include the removal of implanted hardware in infections that occur more than 6 weeks from operative fixation. Given that orthopedic injury constitutes a significant proportion of traumatic injuries, and will likely continue to increase in number in the future, surgeons caring for patients with orthopedic trauma must be able to promptly recognize and manage sepsis secondary to orthopedic injury.

Abstract
Open fractures are highly incident injuries closely related to the modern life, in which accidents caused by motor vehicles or other machines impart high energy to bone tissue. Individual morbidity is represented by the functional impairment resultant of infection, nonunion, or vicious healing. In terms of public health, there are huge costs involved with the treatment of these fractures, particularly with their complications. One of the critical issues in managing open fractures is the use of antibiotics (ATB), including decisions about which specific agents to administer, duration of use, and ideal timing of the first prophylactic dose. Although recent guidelines have recommended starting antibiotic prophylaxis as soon as possible, such a recommendation appears to stem from insufficient evidence. In light of this, we conducted a systematic review, including studies that addressed the impact of the time to first antibiotic and the risk of infectious outcomes. Fourteen studies were selected, of which only four found that the early initiation of treatment with antibiotics is able to prevent infection. All studies had important risks of bias. The results indicate that this question remains open, and further prospective and methodologically sound studies are necessary in order to guide practices and health policies related to this matter.

Abstract
The orthoplastic approach involves the collaboration of orthopedic/trauma surgeons, vascular surgeons and reconstructive microsurgeons. In cases of complex limb fractures, the aims are to optimize blood flow, restore bone stability, reconstruct soft tissue defects, and enhance function and sensitivity. The early administration of antibiotics and a timely, high-quality debridement after initial interdisciplinary assessment are carried out. This is followed by fracture stabilization and temporary wound coverage in order to plan the definitive interdisciplinary procedure. This includes definitive osteosynthesis and soft tissue reconstruction, using local tissue transfer if feasible, or free tissue transfer in cases of extensive trauma zones. The orthoplastic approach allows for faster definitive stabilization, fewer operations, shorter hospital stays, lower complication and revision rates, higher cost-effectiveness and improved long-term function.

Abstract
Of the 27 million surgeries performed in the United States each year, a reported 2.6% result in a surgical site infection (SSI), and Staphylococci species are commonly the culprit. Alternative therapies, such as nitric oxide (NO)-releasing biomaterials, are being developed to address this issue. NO is a potent antimicrobial agent with several modes of action, including oxidative and nitrosative damage, disruption of bacterial membranes, and dispersion of biofilms. For targeted antibacterial effects, NO is delivered by exogenous donor molecules, like S-nitroso-N-acetylpenicillamine (SNAP). Herein, the impregnation of SNAP into poly(lactic-co-glycolic acid) (PLGA) for SSI prevention is reported for the first time. The NO-releasing PLGA copolymer is fabricated and characterized by donor molecule loading, leaching, and the amount remaining after ethylene oxide sterilization. The swelling ratio, water uptake, static water contact angle, and tensile strength are also investigated. Furthermore, its cytocompatibility is tested against 3T3 mouse fibroblast cells, and its antimicrobial efficacy is assessed against multiple Staphylococci strains. Overall, the NO-releasing PLGA copolymer holds promise as a suture material for eradicating surgical site infections caused by Staphylococci strains. SNAP impregnation affords robust antibacterial properties while maintaining the cytocompatibility and mechanical integrity.

Abstract
BACKGROUND Open limb fractures are a time-critical orthopaedic emergency that present to jurisdictional ambulance services. This study describes the demographic characteristics and epidemiological profile of these patients METHODS: We undertook a retrospective analysis of all patients that presented to Queensland Ambulance Service with an open limb fracture (fracture to the humerus, radius/ulna, tibia/fibula or femur) over a two-year period (January 2018 - December 2019). RESULTS Overall, 1020 patients were included. Patients were mainly male (65.9%) and middle-aged (age 41 years, IQR 22-59). Fractures predominately occurred in the lower extremities (64.9%) with transport crashes the primary mechanism of injury (47.8%). The location of the fracture varied depending on the cause of injury, with femur fractures associated with motorcycle crashes, and fractures to the radius/ulna attributed to falls of greater than one metre (p = 0.001). The median prehospital episode of care was 83 min (IQR 62-144) with aeromedical air ambulance involvement and the attendance of a critical care paramedic or emergency physician, both independent factors that increased this time interval. CONCLUSION Open limb fractures are a relatively infrequent injury presentation encountered by ambulance clinicians. The characteristics of these patients is consistent with previously described national and international out-of-hospital trauma cohorts.

Abstract
Background Race and insurance status are independent predictors of healthcare outcomes following lower-extremity trauma. Level 1 trauma centers show better outcomes overall, but it is has not been extensively studied as to whether they specifically lower complication rates and shorten length of stay in those with Black race, with low socioeconomic status, and/or a lack of private health insurance. We performed a study with the objective of determining whether Level I trauma centers can improve the complication rate of those shown to be at high risk of experiencing adverse outcomes due to socioeconomic differences. Hypothesis Level 1 trauma centers will be successful in mitigating the disparity in complication rates and length of stay associated with racial and socioeconomic differences among trauma patients experiencing an open tibia fracture. Patients and methods The National Trauma Databank was reviewed from 2008 to 2015, identifying 81,855 encounters with an open tibia fracture, and 33,047 at a Level I trauma center. Regression models determined effects of race and insurance status on outcomes by trauma center while controlling for confounders. Results Black race [OR 1.36, 95% CI, 1.17-1.58; p < 0.05] and "other" race [OR 1.28, 95% CI, 1.07-1.52; p < 0.05] were associated with higher odds of injury-specific complications. Patients without private insurance and of non-White or Black race in comparison to White patients had a significantly longer length of stay [coefficient 1.66, 95% CI, 1.37-1.94; p < 0.001]. These differences persisted in patients treated at an American College of Surgeons (ACS) Level I trauma center. Discussion Treatment at an ACS Level I trauma center did not reduce the independent effects of race and insurance status on outcomes after open tibia fracture, emphasizing the need to recognize this disparity and improve care for at-risk populations.

Abstract
Severe open fractures present challenges to orthopaedic surgeons worldwide, with increased risks of significant complications. Although different global regions have different resources and systems, there continue to be many consistent approaches to open fracture care. Management of these complex injures continues to evolve in areas ranging from timing of initial operative debridement to the management of critical-sized bone defects. This review, compiled by representative members of the International Orthopaedic Trauma Association, focuses on several critical areas of open fracture management, including antibiotic administration, timing of debridement, bone loss, soft tissue management, and areas of need for future investigation.

Abstract
Introduction Open fractures represent a major source of morbidity. Surgical site infections (SSIs) after open fractures are associated with a high rate of reoperations and hospitalizations, which are associated with a lower health-related quality of life. Early antibiotic delivery, typically chosen through an assessment of the size and contamination of the wound, has been shown to be an effective technique to reduce the risk of SSI in open fractures. The Gustilo-Anderson classification (GAC) was devised as a grading system of open fractures after a complete operative debridement of the wound had been undertaken but is commonly used preoperatively to help with the choice of initial antibiotics. Incorrect preoperative GAC, leading to less aggressive initial management, may influence the risk of SSI after open fracture. The objectives of this study were to determine (1) how often the GAC changed from the initial to definitive grading, (2) the injury and patient characteristics associated with increases and decreases of the GAC, and (3) whether a change in GAC was associated with an increased risk of SSI. Methods Using data from the FLOW trial, a large multicenter randomized study, we used descriptive statistics to quantify how frequently the GAC changed from the initial to definitive grading. We used regression models to determine which injury and patient characteristics were associated with increases and decreases in GAC and whether a change in GAC was associated with SSI. Results Of the 2420 participants included, 305 participants had their preoperative GAC change (12.6%). The factors associated with upgrading the GAC (from preoperative score to the definitive assessment) included fracture sites other than the tibia, bone loss at presentation, width of wound, length of wound, and skin loss at presentation. However, initial misclassification of type III fractures as type II fractures was not associated with an increased risk of SSI (P = 0.14). Conclusions When treating patients with open fracture wounds, surgeons should consider that 12% of all injuries may initially be misclassified when using the GAC, particularly fractures that have bone loss at presentation or those located in sites different than the tibia. However, even in misclassified fractures, it did not seem to increase the risk of SSI.

Abstract
INTRODUCTION Fracture related infection (FRI) may be a devastating complication of open tibial shaft fractures. We sought to determine if antibiotic bead pouch, negative pressure wound therapy, or negative pressure wound therapy over antibiotic beads as the initial coverage method for type IIIB open tibial shaft fractures is associated with risk of FRI. PATIENTS AND METHODS Retrospective cohort study with radiograph and chart review of patients aged ≥16 years with isolated, displaced, extra-articular, Gustilo-Anderson type IIIB open diaphyseal AO/OTA 42 tibial fractures requiring rotational or free tissue transfer for soft tissue coverage at one Level 1 trauma center between 2007 and 2020. An association of dressing applied at the first surgical debridement (application of antibiotic bead pouch, negative pressure wound therapy, or combined therapy) with a primary outcome of FRI requiring debridement or amputation was analyzed by multivariable logistic regression considering demographic, injury, and treatment characteristics. RESULTS 113 patients met eligibility criteria. Median follow-up was 33 months (interquartile range 5-88). 41 patients were initially treated with NPWT, 59 with ABP, and 13 with ABP+NPWT at the initial surgical debridement. 39 (35%) underwent subsequent debridement or amputation for FRI. One amputation occurred in the ABP group for refractory deep surgical site infection (p = 0.630). Initial wound management with an antibiotic bead pouch versus either negative pressure wound therapy alone or negative pressure wound therapy combined with an antibiotic bead pouch was associated with lower odds of debridement or amputation for FRI (β = -1.08, 95% CI -2.00 to -0.17, p = 0.02). CONCLUSIONS In our retrospective analysis, antibiotic bead pouch for initial coverage of type IIIB open tibial shaft fractures requiring flap coverage was associated with a lower risk of FRI requiring debridement or amputation than negative pressure wound therapy applied with or without antibiotic beads. A prospective clinical trial is warranted.

Abstract
BACKGROUND Open fractures have a high risk of infection with limited data correlating timing of prophylactic antibiotic administration and rate of subsequent infection. The Trauma Quality Improvement Program has established a standard of antibiotic administration within 1 hour of arrival, but there is a lack of adequately powered studies validating this quality metric. We hypothesize that open femur and/or tibia fracture patients undergoing orthopedic surgery have a decreased risk of infectious complications (osteomyelitis, deep and superficial surgical site infection) if antibiotics are administered within 1 hour of presentation compared with administration after 1 hour. METHODS The 2019 Trauma Quality Improvement Program was queried for adults with isolated (Abbreviated Injury Scale <1 for the head/face/spine/chest/abdomen/upper extremity) open femur and/or tibia fractures undergoing orthopedic surgery. Transfer patients were excluded. Patients receiving early antibiotics (EA) within 1 hour were compared with patients receiving delayed antibiotics (DA) greater than 1 hour from arrival. RESULTS Of 3,367 patients identified, 2,400 (70.4%) received EA. Patients receiving EA had a higher rate of infections compared with DA (1.1% vs. 0.2%, p = 0.011). After adjusting for age, comorbidities, injury severity, nerve/vascular trauma to the lower extremity, washout of the femur/tibia performed in <6 hours, blood transfusion, and admission vitals, patients in the EA group had a similar associated risk of surgical site infection/osteomyelitis compared with the DA cohort ( p = 0.087). These results remained in subset analyses of patients with only femur, only tibia, and combined femur/tibia open fractures (all p > 0.05). CONCLUSION In this large national analysis, approximately 70% of isolated open femur or tibia fracture patients undergoing surgery received antibiotics within 1 hour. After adjusting for known risk factors of infection, there was no association between timing of antibiotic administration and infection. Reconsideration of the quality metric of antibiotic administration within 1 hour for open fractures appears warranted. LEVEL OF EVIDENCE Therapeutic/Care Management; Level IV.

Effect of Local Antibiotic Prophylaxis on Postoperative Deep Infection in Fracture Surgery: A Systematic Review and Meta-Analysis. J Orthop Trauma 2023; 37:e28-e35. [PMID: 36084224 DOI: 10.1097/bot.0000000000002487] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 09/02/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVES Despite the use of systemic antibiotic prophylaxis, postoperative infection after fracture surgery remains an issue. The purpose of this systematic review and meta-analysis was to evaluate the effect of locally applied antibiotics on deep infection in fracture surgery in both the open and closed fractures. DATA SOURCES A comprehensive search of MEDLINE, Embase, and PubMed was performed from the date of inception to April 15, 2021, and included studies in all languages. STUDY SELECTION Cohort studies were eligible if they investigated the effect on the infection rate of local antibiotic prophylaxis on deep infection after fracture surgery. DATA EXTRACTION This study was conducted according to the Cochrane Handbook for Systematic Reviews and reported as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Risk of bias was assessed using version 2 of the Cochrane risk-of-bias tool for randomized trials and the Methodological Index for Nonrandomized Studies tool where applicable. DATA SYNTHESIS An inverse variance random-effects model was the primary analysis model because of the anticipated diversity in the evaluated populations. Univariate models were used when a single outcome was of interest. CONCLUSIONS The risk of deep infection was significantly reduced when local antibiotics were applied compared with the control group receiving systemic prophylaxis only. This beneficial effect was observed in open fractures but failed to reach statistical significance in closed fractures. This meta-analysis suggests that there may be a significant risk reduction in deep infection rate after fracture surgery when local antibiotics are added to standard systemic prophylaxis, particularly in open fractures. Further high-powered Level I studies are needed to support these findings. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

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
BACKGROUND In the care of open fractures, time to antibiotic administration has been shown to be a critical factor in preventing infection. To help improve outcomes at our institution we designed and implemented an open fracture pathway with the goal of reducing the time from emergency department (ED) arrival to antibiotic administration. Here we evaluate the success of this pathway, propose improvements in the protocol, and provide a framework for initiation at other institutions. METHODS We compared a retrospective prepathway cohort with a prospective postpathway cohort for 1-year pre and postpathway implementation. First, we analyzed the number of patients from outside facilities who had received antibiotics before transfer. For patients who had not received antibiotics before arriving at our institution, we reviewed pathway metrics including time from ED arrival to the ordering and administration of antibiotics, whether the correct antibiotic type was selected, and time to surgical debridement. RESULTS There were 50 patients in the prepathway cohort and 29 in the postpathway cohort. Prepathway 60.5% of transfers (23 of 38) received antibiotics before transfer, whereas post-pathway 90.0% of transfers (18 of 20) received antibiotics ( P =0.032). For patients who had not received antibiotics before arriving at our institution and were included in pathway metric analysis, there were no differences in demographics or fracture characteristics. Time from ED arrival to antibiotic order decreased from 115.3 to 63.5 minutes ( P =0.016). Time from antibiotic order to administration was similar between groups (48.0 vs. 35.7 min, P =0.191), but the overall time from ED arrival to antibiotic administration decreased from 163.3 to 99.2 minutes ( P =0.004). There were no significant differences in whether the correct antibiotic type was chosen ( P =0.354) or time from ED arrival to surgery ( P =0.783). CONCLUSIONS This study provides evidence that for pediatric patients presenting with open fractures, a care pathway can successfully decrease the time from ED arrival to antibiotic administration.

Prior use of antibiotics and immunosuppression are risk factors for fracture-related infection during the COVID-19 pandemic period: a Brazilian prospective cohort study. BMC Musculoskelet Disord 2022; 23:535. [PMID: 35658853 PMCID: PMC9166157 DOI: 10.1186/s12891-022-05493-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 05/23/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Little is known about the role of COVID-19 pandemic period on the epidemiology of fracture-related infection (FRI). The present study summarizes the changes in the prevalence, microbiology, and risk factors of FRI during this period.
Methods
A prospective single-center cohort study assessed in the setting of COVID-19 pandemic (2020–2021), clinical, microbiological aspects, and independent risk factors (RF) of FRI. RFs were estimated by bivariate and multivariable analyses using prevalence ratio (PR) with significance at P < 0.05. Kaplan–Meier analysis was performed to evaluate treatment outcomes.
Results
Overall, 132 patients were analyzed, with patients with age over 65 years accounting 65.1%. FRI was diagnosed in 21(15.9%) patients. Independent RFs for FRI were recent and preoperative use of systemic antibiotics (PR: 7.0, 95% confidence interval (95% CI): 2.2 – 22.4, p = 0.001) and cancer (PR: 9.8, 95% CI: 2.0 – 48.8, p = 0.005). Cultures yielded Gram-negative bacteria in 77.8%, 33.3% were MDR.
Conclusions
We found higher rates of FRI, predominating in the elderly with closed femoral fractures during the COVID-19 pandemic. Prior use of antibiotics and immunosuppression conditions were independent factor for FRI. Our outcomes provide evidence to avoid the empirical use of antibiotics prior to surgery for fracture stabilization.

Abstract
IMPORTANCE Injuries cause 30% more deaths than HIV, TB and malaria combined, and a prospective fracture care registry was established to investigate the fracture burden and treatment in Malawi to inform evidence-based improvements. OBJECTIVE To use the analysis of prospectively-collected fracture data to develop evidence-based strategies to improve fracture care in Malawi and other similar settings. DESIGN Multicentre prospective registry study. SETTING Two large referral centres and two district hospitals in Malawi. PARTICIPANTS All patients with a fracture (confirmed by radiographs)-including patients with multiple fractures-were eligible to be included in the registry. EXPOSURE All fractures that presented to two urban central and two rural district hospitals in Malawi over a 3.5-year period (September 2016 to March 2020). MAIN OUTCOME(S) AND MEASURE(S) Demographics, characteristics of injuries, and treatment outcomes were collected on all eligible participants. RESULTS Between September 2016 and March 2020, 23,734 patients were enrolled with a median age of 15 years (interquartile range: 10-35 years); 68.7% were male. The most common injuries were radius/ulna fractures (n = 8,682, 36.8%), tibia/fibula fractures (n = 4,036, 17.0%), humerus fractures (n = 3,527, 14.9%) and femoral fractures (n = 2,355, 9.9%). The majority of fractures (n = 21,729, 91.6%) were treated by orthopaedic clinical officers; 88% (20,885/2,849) of fractures were treated non-operatively, and 62.7% were treated and sent home on the same day. Open fractures (OR:53.19, CI:39.68-72.09), distal femoral fractures (OR:2.59, CI:1.78-3.78), patella (OR:10.31, CI:7.04-15.07), supracondylar humeral fractures (OR:3.10, CI:2.38-4.05), ankle fractures (OR:2.97, CI:2.26-3.92) and tibial plateau fractures (OR:2.08, CI:1.47-2.95) were more likely to be treated operatively compared to distal radius fractures. CONCLUSIONS AND RELEVANCE The current model of fracture care in Malawi is such that trained orthopaedic surgeons manage fractures operatively in urban referral centres whereas orthopaedic clinical officers mainly manage fractures non-operatively in both district and referral centres. We recommend that orthopaedic surgeons should supervise orthopaedic clinical officers to manage non operative injuries in central and district hospitals. There is need for further studies to assess the clinical and patient reported outcomes of these fracture cases, managed both operatively and non-operatively.

Br J Oral Maxillofac Surg 2021; 60:291-294.

Abstract
Non-condylar mandibular fractures are consdered 'open' fractures and as such are thought to require prophylactic antibiotics. There is no overall consensus on the optimal regimen or choice of antibiotic in the preoperative and postoperative periods due to a lack of high-quality evidence. We therefore set out to ascertain the current UK-wide practice of antibiotic prescribing for non-condylar mandibular fractures. We used a web-based online survey (Google Forms) that was disseminated via email and social media platforms to oral and maxillofacial surgery (OMFS) consultants and trainees of all grades. The questions focused on usual antibiotic practices and typical clinical management of non-condylar mandibular fractures. We gathered information on preoperative antibiotics, and on perioperative and postoperative periods. We collected data from 50 different UK OMFS units representing a broad snapshot of national practice. The majority of responders were speciality trainees (36%) followed by dental core trainees (34%). A total of 45/50 centres routinely admitted patients, and preoperative intravenous antibiotics were commenced on admission by 77/89 respondents, intravenous being the chosen route in all cases. In the preoperative period 81% prescribe co-amoxiclav. In 91% of cases, open reduction and internal fixation (ORIF) was on general emergency (CEPOD) operating lists, whilst dedicated OMFS trauma lists accounted for 9%. With respect to timing, 49% aimed to carry out ORIF within 24 hours from the time of admission, 44% aimed for surgery within 24 - 48 hours, and 6% aimed for surgery on a semielective basis (48 hours or more). Postoperative antibiotics were prescribed routinely by 88% of responders. Preoperative intravenous prophylactic antibiotics are commonplace in non-condylar mandibular fractures. This UK-wide survey demonstrated significant variability in antibiotic prescribing practices, especially in the postoperative period. Most units still rely on CEPOD emergency theatres to provide the capacity for ORIF in this patient group.

Abstract
BACKGROUND Risk stratification of individual patients who are prone to infection would allow surgeons to monitor high-risk patients more closely and intervene early when needed. This could reduce infection-related consequences such as increased health-care costs. The purpose of this study was to develop a machine learning (ML)-derived risk-stratification tool using the SPRINT (Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures) and FLOW (Fluid Lavage of Open Wounds) trial databases to estimate the probability of infection in patients with operatively treated tibial shaft fractures (TSFs). METHODS Patients with unilateral TSFs from the SPRINT and FLOW trials were randomly split into derivation (80%) and validation (20%) cohorts. Random forest algorithms were used to select features that are relevant to predicting infection. These features were included for algorithm training. Five ML algorithms were trained in recognizing patterns associated with infection. The performance of each ML algorithm was evaluated and compared based on (1) the area under the ROC (receiver operating characteristic) curve (AUC), (2) the calibration slope and the intercept, and (3) the Brier score. RESULTS There were 1,822 patients included in this study: 170 patients (9%) developed an infection that required treatment, 62 patients (3%) received nonoperative treatment with oral or intravenous antibiotics, and 108 patients (6%) underwent subsequent surgery in addition to antibiotic therapy. Random forest algorithms identified 7 variables that were relevant for predicting infection: (1) Gustilo-Anderson or Tscherne classification, (2) bone loss, (3) mechanism of injury, (4) multitrauma, (5) AO/OTA fracture classification, (6) age, and (7) fracture location. Training of the penalized logistic regression algorithm resulted in the best-performing prediction model, with AUC, calibration slope, calibration intercept, and Brier scores of 0.75, 0.94, 0.00, and 0.076, respectively, in the derivation cohort and 0.81, 1.07, 0.09, and 0.079, respectively, in the validation cohort. CONCLUSIONS We developed an ML prediction model that can estimate the probability of infection for individual patients with TSFs based on patient and fracture characteristics that are readily available at hospital admission.

Abstract
Open fractures of the lower limb remain a potentially devastating group of injuries that are challenging to manage. The primary aims of treatment are to optimise limb function and avoid serious complications such as infection and non-union, which are costly for both the patient and healthcare system. The management of these fractures has evolved significantly, and this is evident following the creation of national open fracture guidelines and a formal trauma system. These have served to standardise care for these injuries in the United Kingdom. The aim of this review is to update our colleagues on the current standard of lower limb open fracture care in the United Kingdom, and the impact this has had on patient outcomes.
