Objectives. Open fracture classification systems are limited in their use. Our objective was to classify open tibia and femur fractures using the OTS classification system in a region with high incidence of gunshot fractures. One hundred and thirty-seven patients with diaphyseal tibia and femur open fractures were identified from a prospectively collected cohort of patients. This database contained all cases (closed and open fractures) of tibial and femoral intramedullary nailed patients older than 18 years old during the period of September 2017 to May 2021. Exclusion criteria included closed fractures, non-viable limbs, open fractures > 48 hours to first surgical debridement and patients unable to follow up over a period of 12 months (a total of 24). Open fractures captured and classified in the HOST study using the Gustilo-Anderson classification, were reviewed and reclassified using the OTS open fracture classification system, analysing gunshot fractures in particular. Ninety percent were males with a mean age of 34. Most common mechanism was civilian gunshot wounds (gsw) in 54.7% of cases. In 52.6% of cases soft tissue management was healing via secondary intention, these not encompassed in the classification. Fracture classification was OTS Simple in 23.4%, Complex B in 24.1% and 52.6% of cases unclassified. The OTS classification system was not comprehensive in the classification of open tibia and femur fractures in a setting of high incidence of gunshot fractures. An amendment has been proposed to alter acute management to appropriate wound care and to subcategorise Simple into A and B subdivisions; no soft tissue intervention and primary closure respectively. This will render the OTS classification system more inclusive to all open fractures of all causes with the potential to better guide patient care and clinical research

Many studies report the incidence and prevalence of surgical site infections (SSIs) following open fractures; however, there is limited information on the treatment and subsequent outcomes of superficial SSIs in open fracture patients. There is also a lack of clinical studies describing the prognostic factors that are associated with failure of antibiotic treatment (non-operative) for superficial SSI. To address this gap, we used data from the FLOW (Fluid Lavage in Open Fracture Wounds) trial to determine how successful antibiotic treatment was for superficial SSIs and to identify prognostic factors that could be predictive of antibiotic treatment failure. This is a secondary analysis of the FLOW trial dataset. The FLOW trial included 2,445 operatively managed open fracture patients. FLOW participants who had a non-operatively managed superficial SSI diagnosed in the 12 months post-fracture were included in this analysis. Participants were grouped into two categories: 1) participants whose superficial SSI resolved with antibiotics alone and 2) participants whose SSI did not resolve with antibiotics alone (defined as requiring surgical management or SSI being unresolved at final follow-up (12-months post-fracture for the FLOW trial)). Antibiotic treatment success and the date when this occurred was defined by the treating surgeon. A logistic binary regression analysis was conducted to identify factors associated with superficial SSI antibiotic success. Based on biologic rationale and previous literature, a priori we identified 13 (corresponding to 14 levels) potential factors to be included in the regression model. Superficial SSIs were diagnosed in168 participants within 12 months of their fracture. Of these, 139 (82.7%) had their superficial SSI treated with antibiotics alone. The antibiotic treatment was successful in resolving the superficial SSI in 97 participants (69.8%) and unsuccessful in resolving the SSI in 42 participants (30.2%). We found that superficial SSIs that were diagnosed later in follow-up were associated with failure of treatment with antibiotic alone (Odds ratio 1.05 for every week in diagnosis delay, 95% Confidence Interval 1.004–1.099; p=0.03). Age, sex, fracture severity, fracture pattern, wound size, time from injury to initial surgical irrigation and debridement were not associated with antibiotic treatment failure. Our secondary analysis of prospectively collected FLOW data found antibiotics alone resolved superficial SSIs in 69.8% of patients diagnosed with superficial SSIs. We also found that superficial SSIs that were diagnosed earlier in follow-up were associated with successful treatment with antibiotics alone. This suggests that if superficial SSIs are diagnosed and treated promptly, there is a higher probability that they will resolve with antibiotic treatment

The aim of this abstract is to show that when dealing with an infected non-union, all possibilities of treatment must be considered in order to choose the best treatment plan for each patient. This case shows the evolution of an infected non-union following type III open fractures which, after the used of several methods that failed, had to be solved with amputation. We present a case report of a 41 years old man, with a type IIIA open fracture of the right tibia and fibula. Initially, he was treated with an external fixator, which was removed and plate implanted. After this, he who presented to us with an infected non-union. He was submitted to surgery, the plate was removed and a circular external fixator was used. Six months later, the external fixator was removed and a reamed intramedullary nail was implanted with bone graft from iliac crest. One year later, the facture site was still mobile, so he was submitted to fixation with internal plate. As this last method also failed, a bellow knee amputation was performed, 4 years after the initial event. After several attempts with several distinctive methods, the infected non-union had to be solved with the sacrifice of the limb. The treatment of infected non-union is one of the most difficult in Orthopedic Surgery. There are several procedure that can be used. When all these fail, amputation and consequent limb prosthetic substitution, might allow the patient to return to the society

Infection is a common complication of severe open fractures and compromises bone healing. The present standard of care is a two-stage approach comprising of initial placement of antibiotic-impregnated PMMA beads to control infection followed later by bone grafting. Although the systemic antibiotics and PMMA/antibiotic beads control the infection initially, there are often residual bacteria within the wound. After grafting and definitive closure, the implanted graft is placed in an avascular defect and could function as a nidus for infection. Bioactive porous polyurethane (PUR) scaffolds have been shown to improve bone healing by delivering recombinant human bone morphogenetic protein-2 (BMP-2) and reduce infection by delivering antibiotics. The release kinetics of the BMP-2 were an initial burst to recruit cells and sustained release to induce the migrating cells. The Vancomycin (Vanc) release kinetics were designed to protect the graft from contamination until vascularisation by having an initial burst and then remaining over the MIC for Staph. aueus for two months. In this study, PUR+BMP-2+Vanc scaffolds were first tested in a non-infected critical size rat femoral segmental defect and was found to perform comparably to PUR+BMP-2, thus indicating that Vanc did not hinder bone healing. PUR+BMP-2+Vanc scaffolds were subsequently evaluated in an infected critical size rat femoral segmental defect. The dual delivery approach resulted in significantly more new bone formation and infection control than both PUR+BMP-2 and the collagen+BMP-2 treatments. These data indicate that the dual-delivery strategy effectively protects the graft from infection during wound healing and regenerates more bone in contaminated defects. This moderately osteoconductive bone graft is capable of being injected, provides a more sustained release of BMP-2 than the collagen sponge, and can release antibiotics for over 8 weeks. The dual-delivery approach may improve patient outcomes of open fractures by protecting the osteoinductive graft from colonization until vascularization occurs

Aim. Open fractures still have a high risk for fracture-related Infection (FRI). The optimal duration of perioperative antibiotic prophylaxis (PAP) for open fractures remains controversial due to heterogeneous guidelines and highly variable prophylactic regimens in clinical practice. In order to provide further evidence with which to support the selection of antibiotic duration for open fracture care, we performed a preclinical evaluation in a contaminated rabbit fracture model. Method. A complete humeral osteotomy in 18 rabbits was fixed with a 7-hole-LCP and inoculated with Staphylococcus aureus (2×106 colony forming units, CFU per inoculum). This inoculum was previously shown to result in a 100% infection rate in the absence of any antibiotic prophylaxis. Cefuroxime was administered intravenously in a weight adjusted dosage equivalent to human medicine (18.75 mg/kg) as a single shot only, for 24 hours (every 8 hours) and for 72 hours (every 8 hours) in separate groups of rabbits (n=6 per group). Infection rate per group was assessed after two weeks by quantitative bacteriological evaluation of soft tissue, bone and implants. Blood samples were taken from rabbits preoperatively and on days 3, 7 and 14 after surgery to measure white blood cell count (WBC) and C-reactive protein (CRP) levels. Results. Duration of PAP had a significant impact on the success of antibiotic prophylaxis. The single shot regimen completely failed to prevent infection. All samples (soft tissue, implant and bone) from this group displayed high numbers of bacteria. Additionally, abscesses were present in two of six rabbits. The 24-hour regimen showed a reduced infection rate (1 out of 6 rabbits infected), but only the 72-hour course was able to prevent FRI in all animals in our model. After an initial postoperative peak on day three, CRP levels then decreased to baseline (approx. 30 µg/ml) in the 24h-group and 72h-group, but remained significantly higher in the single shot group at day 7 and 14 (p<0.05). Conclusions. When contamination with high bacterial loads is likely (e.g. in an open fracture situation), a 72-hour course of intravenous cefuroxime appears to be superior in preventing FRI compared to a single shot or 24-hour antibiotic regimen.

Background. Traditional recommendations suggest that open fractures require urgent surgical debridement to reduce infection. However, this has recently been challenged by a number of investigations. However, in many cases, these studies were not able to control for important confounding factors. The purpose of our study was to evaluate the relationship between delay to definitive surgical debridement while controlling for important confounders. Method. 364 patients with 459 open fractures treated at a level one trauma centre over four years were reviewed. Time to definitive surgical debridement was modelled as a predictor of infection while controlling for fracture grade, anatomic site of fracture, and presence of significant contamination. Time to debridement was modelled as both a continuous variable and a categorical variable with cut off points at 6 and 12 hours of delay. Results. 46 deep infections occurred in 459 fractures(10%). There were no infections among grade one open fractures(0/55). Delay to debridement using cut-points of 6 hours and 12 hours was not associated with an increased infection rate. However, with delay to debridement analyzed as a continuous variable each additional hour of delay was associated with an increase in the odds of infection(OR=1.033 95%CI 1.01–1.057). Multivariable analysis also showed that infection was associated with tibial fractures(OR=2.44 95%CI 1.26–4.73), higher Anderson & Gustillo grade (OR=1.99 95%CI 1.004–3.954), and gross contamination (OR=3.12 95%CI 1.36–7.36). Among more severe open fractures the impact of delay to debridement translates into a larger absolute increase in probability of infection. Conclusion. We recommend that higher grade open fractures be treated with definitive debridement as soon as possible given that the risk of infection increases in a linear fashion with time delay. For severe open fractures, especially tibial, we recommend emergent debridement as soon as the patient has been resuscitated and is stable enough to undergo surgery

This clinical case refers to a male patient, 45 years old, with a past medical history of Hepatitis C, admitted at the Emergency Department on July 2014, after a fall from 7 meters high at his workplace – dump – which resulted in an open fracture of the distal end of the right forearm bones – Gustillo & Anderson IIIA. With this work, the authors aim to describe the evolution of the patient's clinical status, from the initial fracture to the septic arthritis of the right wrist, as also the surgical interventions and other treatments he has undergone. There were used all patient's records from Hospital's archives, including Emergency Department registry, Clinical Diaries, Operative Reports, and results of diagnostic exams. It was also revised all patient's clinical process, with support of photographs obtained during the successive revaluations. The clinical case we present on this work began on July 2014, when the patient suffered an open fracture – Gustillo & Anderson IIIA – on the distal end of the right forearm bones. The lesion was subjected to washing, closed reduction and internal fixation with Kirschner wires, and also a cycle of antibiotic. At the fourth day after surgery, because of an unfavorable evolution of the wound, the patient was submitted to a bulky abscess drainage and a joint osteotaxis. About 1 month and a half after the traumatic event, it was performed a revision of the osteotaxis, following a failed attempt of osteosynthesis. By unfavorable evolution of the clinical status, with the development of septic arthritis in the right wrist, it was decided to undertake a Masquelet technique. Analyzing the evolution of the patient's clinical status, the authors conclude that, besides the appropriate therapeutic options taken at each stage, the development of septic arthritis at the right wrist was inevitable. This framework, in association to the fact that this is a 45 years old patient, with the dominant hand affected, raises issues of questionable therapeutic order

This work refers to a male patient, 25 years of age, admitted in the Emergency Department following a bicycle accident, of which resulted an open fracture of the right forearm bones – Gustillo & Anderson I. With this work, the authors have as objective the description of the patient's clinical condition – starting with the fracture, over to the osteomyelitis – as well as the surgical procedures and remaining treatments he was submitted to. The authors used the patient's records from Hospital's archives, namely records from the Emergency Department, Operating Room, Infirmary and Consultation, and also the diagnostic exams performed throughout the patient's clinical evolution. This clinical case began in May 2013, when the patient suffered an open fracture of the right forearm bones – Gustillo & Anderson I – due to a bicycle accident. At the time, the exposure site was thoroughly rinsed, a cast immobilization was made, and antibiotics were prescribed. In the fifth day following the trauma, the patient was submitted to an open reduction with internal fixation with plate and screws of both forearm bones. In the following period, the distal segment of the suture suffered necrosis, exposing the radial plate and the tendons of the first dorsal compartment. The Plastic Surgery team was then contacted, proposing the execution of a graft over the exposed area, which was made in August 2013. In the postoperative period, about half the graft lost its viability and it was noted that a radial pseudoarthrosis had developed – in the context of osteomyelitis – with a defect of about 9 centimeters. This condition prompted the extraction of the osteosynthesis material, about 4 months after its application, and at the same time the first stage of a Masquelet Technique was performed. The second stage of the aforementioned procedure was carried out two months later. Currently, the patient is clinically stable, with right hand mobility acceptable for his daily living activities. Analyzing the patient's clinical evolution, we concluded that, even though the adequate therapeutic decisions have been made in each stage, the development of osteomyelitis was inevitable. This realization, in association with the patient's young age, raises debatable questions of therapeutic order

The optimal choice of irrigating solution or irrigating pressure in the initial management of open fracture wounds remains controversial. FLOW compared the effect of castile soap versus normal saline, and low versus high pressure pulsatile lavage on one year re-operation rates in patients with open fracture wounds. We conducted a multicentre, blinded, two-by-two factorial, pilot randomised trial of 111 patients with open fracture wounds receiving either castile soap solution or normal saline and either high or low pressure pulsatile lavage. The primary outcome, re-operation within one year, included infections, wound healing problems, and nonunions. Secondary outcomes included all operative and non-operative infections, wound healing problems, nonunion and functional outcomes. We followed the intention to treat principle. Eighty-nine patients (80.2%) completed the 12-month follow-up. As anticipated in this small-sample-size pilot study, results were compatible with substantial benefit and substantial harm. The hazard ratio (HR) for re-operation with castile soap was 0.77 (95% Confidence Interval (CI) 0.35 to 1.69, p=0.52). With low pressure lavage, the hazard ratio for the risk of re-operation was 0.56, 95% CI 0.25 to 1.27, p=0.17. Secondary outcomes showed a significant relative risk reduction for nonunion of 63% in favour of castile soap (p=0.036), and a trend for a relative risk reduction for nonunion of 44% in favour of low pressure lavage (p=0.22). Functional outcome scores showed no significant differences at any time point between groups. The FLOW pilot randomised controlled trial demonstrated the possibility that the use of low pressure may decrease the re-operation rate for infection, wound healing problems, or nonunion. Our findings provide compelling rationale for continued investigation in a pivotal FLOW trial of 2280 patients

Background. In 2011 Aird et al published their results of the effects of HIV on early wound healing in open fractures treated with internal and external fixation. The study was conducted between May 2008 and March 2009 and performed in semi-rural area of KwaZulu-Natal, South Africa. These results suggested that HIV is not a contraindication to internal or external fixation of open fractures, as HIV is not a significant risk factor for acute wound implant infection. We present a longer term follow up of this same cohort of patients from the original study. Methods. From March 2011 to January 2012 we attempted to contact all patients from Airds original study. A simple telephonic questionnaire was obtained from all the patients contacted, regarding possible late sepsis, non-union and implant removal. Patients were requested to visit the outpatient department for a clinical assessment, a repeat HIV test and new X-rays. Results. Of the initial 133 patients, 27 patients had external fixators, which were removed, leaving 106 patients with implants in situ at the time of follow up. Six patients had died, 4 of AIDS, 1 of a traffic accident and one of community assault. We were able to obtain telephonic questionnaires of 46 patients in total. Of these 46 patients, 31 were seen at a dedicated research clinic for re-assessment. In the initial study, 33 patients were HIV positive. We re-assessed 14 of these HIV positive patients and of these, 1 patient had metal removed for sepsis and 1 patient had a non-union. The remaining 12 patients had implants in situ without sepsis or non-union. Conclusion. This is the longest follow up to date of the effect of HIV on surgical implants following open fractures. Our results suggest HIV is not a contraindication for internal surgical fixation of open fractures in HIV positive patients with regards to long term sepsis and the risk of non-unions.

Aim. Antibiotic prophylaxis is critical for the prevention of fracture related infection (FRI) in trauma patients, particularly those with open wounds. Administration of prophylactic antibiotics prior to arrival at the hospital (e.g. by paramedics) may reduce intraoperative bacterial load and has been recommended; however scientific evidence for pre-hospital administration is scarce. Methods. The contaminated rabbit humeral osteotomy model of Arens was modified to resemble the sequence of events in open fractures. In an initial surgery representing the “accident”, a 2mm mid-diaphyseal hole was created in the humerus and the wound was contaminated with a clinical Staphylococcus aureus strain (mean 1.6×106 Colony Forming Units, CFU). The animals were allowed recover for 4 hours mimicking the period from trauma to debridement. At this time, a second procedure was performed in order to debride and irrigate the wound, and to fix a complete osteotomy that was made through the initial defect. Three test groups were included (n=8 rabbits per group): 1) no antibiotic therapy; 2) standard “in-hospital” antibiotic prophylaxis (24 hours therapy starting 30 minutes before surgery); 3) “pre-hospital” antibiotics (single dose 15 minutes after the “accident”). The antibiotic used was cefuroxime and was administered in a weight-adjusted dosage. Results. In the absence of any antibiotic administration (group 1), high bacterial counts were identified at fixation (1.89×106 CFU) and at euthanasia (day 7, 7.70×107 CFU) in all rabbits. When 24 hours of antibiotics were administered commencing “in hospital” (group 2), the bacterial load during fixation surgery was slightly reduced (CFU 9.88×105) and 50% of animals were infected at euthanasia. When one single shot of antibiotics was administered in the “pre-hospital” setting (group 3), the bacterial load during fixation surgery was significantly lower than for both groups 1 and 2(CFU 2.34×103) yet all animals were infected at euthanasia. Conclusions. Early pre-hospital administration of antibiotics significantly reduced the bacterial load in the operative field at the time of debridement compared to regular prophylaxis. However, continuation of systemic antibiotics is necessary in order to prevent infection in this model

Open fractures are common, and infection a frequent complication. There is still uncertainty regarding the urgency of initial treatment. The majority of animal studies indicate that early irrigation and debridement reduces infection; unfortunately, these studies often do not involve antibiotics. Clinical studies indicate that the timing of initial debridement does not affect the infection rate. These studies are observational and fraught with confounding variables. The purpose of this study was to control for these variables using an animal model incorporating both systemic antibiotics and surgical treatment. This study used a segmental defect rat femur model contaminated with Staphylococcus aureus and treated with a 3 day course of systemic cefazolin (5 mg/Kg 12 hourly) and surgical treatments, both of which were initiated independently at 2, 6 and 24 hour time points. After 14 days bone and hardware was harvested for separate microbiological analysis. These results show that the earlier systemic antibiotic treatment or surgery is initiated. When antibiotics are started at 2 hours, delaying surgical treatment from 2 to 6 hours significantly increases infection (p=0.047). However, delaying surgery to 24 hours increases infection, but not significantly (p=0.054). The timing of antibiotics had a more significant effect on the proportion of positive samples than earlier surgery. At the 2 and 6 hour treatments, the p value was 0.004 and for the 6 and 24 timings it was 0.003. Surgery and antibiotics at 2 hours completely eradicates the bacteria, but surgical delay for 6 hours appears to allow the bacteria to form non-susceptible colonies. Delaying antibiotics to 6 or 24 hours had a profound detrimental effect on the infection rate regardless of timing of surgery. These findings are consistent with the concept that bacteria progress from a vulnerable planktonic form to a treatment-resistant biofilm

We aimed to quantify the health related quality of life in a series of patients suffering a variety of different tibial injuries. Patients with previous tibial injury, randomly selected from our trauma database, who successfully completed their entire course of treatment at our institution, were recalled for final assessment. Mean time to final follow-up was 37.4 months. Statistical analysis was performed using SPSS computer software. Overall, 130 patients were evaluated. There was no significant difference in the self-care dimension between the groups. Psychological problems were common in patients with IIIb and IIIc fractures, as well as amputees, with the highest incidence in those with IIIc fractures. Patients who had undergone amputation and those with IIIb open fractures reported problems with mobility significantly more frequently than those who had IIIc type injuries. However, this could be partially attributed to the significant difference in mean age between groups, with patients sustaining IIIc injuries being younger (31.9 vs 46.9). Patients with IIIb and IIIc type fractures reported significantly more problems with pain compared with those who had undergone amputation. Interestingly, patients who had undergone fasciotomy reported pain as frequently as amputees. Regarding the VAS, only patients with closed fractures reported significantly different scores from the mean of all the other groups. These data represent the health related quality of life of patients having suffered the full spectrum of tibial injury and should be considered when determining the treatment options for these patients

Since its approval by the FDA two decades ago, Negative Pressure Wound Therapy (NPWT) has become a valuable asset in the management of open fractures with significant soft tissue damage as those seen in high velocity gunshot injuries. These lesions are often associated with grossly contaminated wounds and require a prompt and effective approach. Wound dehiscence and surgical site infection are two of the most common post-operative complications, with poor results when treated with standard gauze dresses. NPTW comes as a legitimate resource promoting secondary intention healing through increased granulation and improved tissue perfusion, as well as continuous local wound drainage preventing bacterial growth and further infection. Recent evidence-based guidelines are still limited for use of NPWT in the treatment of Gustilo-Anderson type IIIB open fractures and there are few cases in literature reporting the management of upper extremity injuries. We present and discuss a successful case of a type IIIB open humeral fracture wound treated with NPWT. A 38-years-old male was admitted to the Emergency Room with a type IIIB open humeral fracture as a result of a gunshot with extensive soft tissue damage. IV antibiotic therapy was promptly started followed by surgical stabilization by intramedullary nailing with primary wound closure. The patient presented an early surgical site infection with wound dehiscence requiring secondary debridement with poor subsequent healing and deficient soft tissue coverage. After ineffective 28 days of standard gauze dresses we started NPWT. NPTW was applied using foam coverage over the dehiscence area with visible results after 13 days and complete granulation of the skin defect by the 28th day. The wound healed completely after 14 weeks of NPWT. The fracture evolved into a painless pseudarthrosis revealing an excellent functional recovery and an acceptable aesthetic result. NPTW is a valuable, effective, and well tolerated resource in the treatment of open fractures with extensive soft tissue damage such as Gustilo-Anderson type IIIB fractures. It should be considered not just as a salvage procedure but as well as a primary option especially in grossly contaminated wounds. No benefits in any form have been received from a commercial party

Aims. The BOA/BAPRAS guidelines for the management of open tibial fractures (2009) recommend early senior combined orthoplastics input and appropriate facilities to manage a high caseload. St Georges Hospital is one of four London Trauma Centres fulfilling these criteria. Our aim is to determine whether becoming a trauma centre has affected the management of patients with open tibial fractures. Methods. Data were obtained prospectively on consecutive open tibial fractures during two 8 month periods: before and after becoming a Major Trauma Centre (May 2009–Dec 2009 and April 2010–Oct 2010 respectively). Data on patient pathway including, admitting hospital, length of stay, timing and number of operations were recorded. Results. 29 open tibial fractures were admitted during the 8 months after designation as a major trauma centre compared to 15 before. 72% of patients came directly, or as A&E hot transfers (previously 60%). Of the eight tertiary transfers, six were from hospitals outside the South West Trauma Network. The time to transfer patients initially admitted to local orthopaedic departments has fallen from 8.6 to 1.6 days. Despite this improvement as a trauma centre, these patients remained in hospital longer (16.3 vs 14.9) and had more operations (3.7 vs 2.6) than direct admissions. As a trauma centre there were improvements in time to definitive skeletal stabilisation (4.7 to 2.2), skin coverage (8.3 to 3.7 days), average number of operations (4.2 to 2.3) and average length of hospital admission fell from 23 to 16 days. Conclusions. The volume and management of open tibial fractures has been directly affected by introduction of a trauma centre within the London Trauma Network. Implementation of BOAST guidelines has resulted in improved management of open lower limb fractures independent of fracture grade. Our data strongly support the continuing development of trauma networks

We present a novel approach to the management of patients with longstanding heel ulcers complicated by open calcaneal fractures. The principles of management of diabetic foot ulcers were combined with applied physiology of fracture healing. Case notes of 6 consecutive patients who presented to our diabetic foot clinic between January 2009 and December 2009 were reviewed. Type of diabetes, duration of heel ulcer, type of fracture and treatment given were recorded. Initial treatment consisted of regular local debridement and application of dressing. Vacuum Assisted Continuous (VAC) pump application was deferred until 6 weeks to preserve fracture hematoma and thereby initiate fracture healing. In all patients, VAC pump was started at 6 weeks and continued till healing of ulcer to adequate depth. Infection was treated aggressively with appropriate antibiotics according to the microbiology results. The average age was 53 (40-60) and the mean duration of follow up was 6 months. All wound healed completely, fractures united and patients returned to previous function. An open calcaneal fracture presents a severe injury likely to be complicated by infection and consequent osteomyelitis leading to amputations. In our group of patients, a novel treatment approach consisting of multidisciplinary model resulted in successful limb preservation and return to function

Introduction. Open fractures of the tibia are disabling injuries with a significant risk of deep infection. Treatment involves early antibiotic administration, early and aggressive surgical debridement, and may require complex soft tissue coverage techniques. The extent of disruption to the skin and soft-tissue envelope often varies, with ‘simple’ open fractures (defined by the Orthopaedic Trauma Society (OTS) open fracture severity classification) able to be closed primarily, whilst others may require shortening or soft-tissue reconstruction. This study aimed to determine whether OTS simple tibial open fractures received different rates of adequate debridement and plastic surgical presence at initial debridement, compared with OTS complex injuries, and whether rates of fracture-related infection, nonunion, or reoperation differed between the groups. Materials & Methods. A consecutive series of open tibia fractures managed at a tertiary UK Major Trauma Centre between January 2021 and November 2022 were included. Patient demographics, injury characteristics, timing of antibiotic delivery, timing and method of definitive fixation, and frequency of plastic surgical presence at initial debridement were retrospectively collected. The delivery of bone ends at initial debridement was used as a proxy for adequacy of surgical debridement. The primary outcome measure was rate of fracture-related infection, secondary outcomes included rates of reoperation, nonunion, and amputation. Chi2 Tests and independent samples T-tests were used to assess nominal and continuous outcomes respectively between simple and complex injuries. Ordinal data was assessed using nonparametric equivalent tests. Results. 79 patients with open fractures of the tibia were included. 70.8% of patients were male, with mean age 50.4 years (SD 19.2) and BMI 26.4 Kg/m2 (SD 6.0). Injuries were mostly sustained by low-energy falls (n = 28, 35.4%) and from road traffic accidents (n = 26, 32.9%). 27 (34.2%) were OTS simple open fractures. Simple open fractures were most commonly Gustillo-Anderson grade 1 (38.5%), or 2 (30.8%), whilst complex open fractures were mostly grade 3B (66.7%) (p < 0.001). Fracture-related infection rates in OTS simple and complex open fractures were 25.9% and 25.5% respectively (p = 0.967), and nonunion rates were 32% and 37.8% (p = 0.637). Primary amputation was less common in simple (0%) than in complex open fractures (20%, p = 0.012), there were no differences in delayed amputation rates (7.4% and 6% respectively, p = 0.811). Simple open fractures were less likely to have plastic surgeons present at initial debridement compared to complex open fractures (18.5% and 44%, p = 0.025), and less likely to have bone ends delivered through the skin at initial debridement (25.9% and 61.2%, p = 0.003). There were no differences in patient age, delays to antibiotic administration, or reoperation rates between OTS simple and OTS complex fractures (p > 0.05). Conclusions. Despite involving less significant soft tissue injury, OTS simple open tibia fractures had comparable deep infection and nonunion rates to complex fractures and received early plastic surgical input and adequate debridement less frequently. The severity of open fractures with less significant soft tissue injury may be underrecognized and therefore undertreated, although further prospective study is needed

Introduction. Open fractures are complex injuries associated with substantial morbidity. These injuries are associated with harm to both physical and emotional health as well as preclusion of work, social, and leisure activities. Patient reported outcome measures (PROMs) and health related quality of life are critical indicators of successful rehabilitation following open fracture treatment. This study aimed to measure the PROMs for patients with open lower limb fractures and investigate the relationship with injury severity. Materials & Methods. A retrospective cohort study was performed at a single major trauma centre in the UK. All adult patients with an open lower limb fracture were eligible for inclusion. Patients were identified through a search of a local Open Fracture Database. Epidemiological, clinical, and fracture classification data were obtained by reviewing case notes. Lower Extremity Function Scale (LEFS) and EQ5-D were used as PROMs and measured by a postal questionnaire, alongside return to employment data. Results. A total of 73 patients responded to the questionnaire. Median LEFS was 42 (IQR 26.5 – 59.5), and median EQ5-D was 0.69 (IQR 0.48 – 0.89). There was no significant association between open fracture classification and PROMs. Over 40% of patients reported a change in employment due to their injury. Those who changed jobs had a statistically significant reduction in the EQ5-D of 0.12 (p = 0.021); no significant difference existed in LEFS. Conclusions. This study demonstrates the devastating functional impact of open fractures. This cohort of open injuries reported lower functional and quality-of-life measures compared to population norms. Injury classification was not a valuable predictor of PROMs. A substantial proportion of patients were forced to change employment due to their injury, and these patients reported a significantly lower quality of life. Further work is required to understand the factors contributing to open fracture PROMs

Introduction. We present a case of a 49-year-old patient who initially presented in May 2020 with an open pilon fracture. Managed with initial debridement, fixation and flap - who subsequently underwent circular frame application for failure of fixation, requiring a transport to fusion frame who developed beta-haemolytic streptococcus A within the site of the proximal corticotomy. Materials & Methods. A systematic review of the literature was conducted searching EMBASE, MEDLINE and Cochrane library for all articles discussing infected bone regenerate- a paucity of information was found. Abstracts were independently reviewed by 2 authors (LH and LT). In total, there were 16 papers, and then subsequently analysed we identified two case reports regarding infected regenerate. Results. Developing an infection in a regenerate is highly rare with very few reported cases within the published literature. The literature identified risk factors for an infected regenerate, with open fracture and smoking being the two consistent factors. The open fracture deep infection rate is cited at 10% in most publications, this is at the site of the open fracture and not within the regenerate. Conclusions. Infection within the regenerate during distraction osteogenesis is highly unusual, with only two other published papers in the literature to the best of our knowledge. This should be borne in mind when managing patients with infection of unknown sources in cases of distraction osteogenesis
