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

Introduction. Open tibial fractures (OTF) rank first among lower limb fractures in sub-Saharan Africa and bone infection remains the main challenge. The aim of this study was to identify the factors associated with chronic bone infection after OTF in a limited-resource setting. Methods. Patients aged 18 years and older, who underwent OTF treatment in a tertiary care hospital during the period from December 2015 to December 2020 were included in this retrospective study. Patients were contacted via phone calls and invited for a final clinical and radiological evaluation. Patients who met diagnostic criteria of chronic osteomyelitis were identified. Logistic regression was used to determine the predictive factors of OTF related chronic osteomyelitis. Results. With a mean follow-up period of 29.5±16.6 months, 33 patients out of 105 (31.4%) presented with chronic osteomyelitis. We found that time to first debridement within 6 hours (OR=0.18, 95% CI: 0.05 – 0.75, p=0.018) and severity of OTF according to Gustilo-Anderson classification (OR=2.06, 95% CI:1.34 – 3.16, p=0.001) were the independent predictive factors of chronic bone infection. Neither age, gender, socio-economic level, polytrauma, HIV status, diabetes mellitus, time to definitive surgery, were associated with chronic osteomyelitis. Conclusion. The rate of chronic bone infections after OTF is still high in the sub-Saharan African context. In addition to the overall improvement in the management of open leg fractures in those settings, emphasis should be placed on very early initial debridement to reduce the burden of these infections. Keys words. open tibial fractures, chronic bone infection, predictive factors

Open limb fractures are typically due to a high energy trauma. Several recent studied have showed treatment's superiority when a multidisciplinary approach is applied. World Health Organization reports that isolate limb traumas have an incidence rate of 11.5/100.000, causing high costs in terms of hospitalization and patient disability. A lack of experience in soft tissue management in orthopaedics and traumatology seems to be the determining factor in the clinical worsening of complex cases. The therapeutic possibilities offered by microsurgery currently permit simultaneous reconstruction of multiple tissues including vessels and nerves, reducing the rate of amputations, recovery time and preventing postoperative complications. Several scoring systems to assess complex limb traumas exist, among them: NISSSA, MESS, AO and Gustilo Anderson. In 2010, a further scoring system was introduced to focus open fractures of all locations: OTA-OFC. Rather than using a single composite score, the OTA-OFC comprises five components grades (skin, arterial, muscle, bone loss and contamination), each rated from mild to severe. The International Consensus Meeting of 2018 on musculoskeletal infections in orthopaedic surgery identified the OTA-OFC score as an efficient catalogue system with interobserver agreement that is comparable or superior to the Gustilo-Anderson classification. OTA-OFC predicts outcomes such as the need for adjuvant treatments or the likelihood of early amputation. An orthoplastic approach reconstruction must pay adequate attention to bone and soft tissue infections management. Concerning bone management: there is little to no difference in terms of infection rates for Gustilo-Anderson types I–II treated by reamed intramedullary nail, circular external fixator, or unreamed intramedullary nail. In Gustilo-Anderson IIIA-B fractures, circular external fixation appears to provide the lowest infection rates when compared to all other fixation methods. Different technique can be used for the reconstruction of bone and soft tissue defects based on each clinical scenario. Open fracture management with fasciocutaneous or muscle flaps shows comparable outcomes in terms of bone healing, soft tissue coverage, acute infection and chronic osteomyelitis prevention. The type of flap should be tailored based on the type of the defect, bone or soft tissue, location, extension and depth of the defect, size of the osseous gap, fracture type, and orthopaedic implantation. Local flaps should be considered in low energy trauma, when skin and soft tissue is not traumatized. In high energy fractures with bone exposure, muscle flaps may offer a more reliable reconstruction with fewer flap failures and lower reoperation rates. On exposed fractures several studies report precise timing for a proper reconstruction. Hence, timing of soft tissue coverage is a critical for length of in-hospital stay and most of the early postoperative complications and outcomes. Early coverage has been associated with higher union rates and lower complications and infection rates compared to those reconstructed after 5-7 days. Furthermore, early reconstruction improves flap survival and reduces surgical complexity, as microsurgical free flap procedures become more challenging with a delay due to an increased pro-thrombotic environment, tissue edema and the increasingly friable vessels. Only those patients presenting to facilities with an actual dedicated orthoplastic trauma service are likely to receive definitive treatment of a severe open fracture with tissue loss within the established parameters of good practice. We conclude that the surgeon's experience appears to be the decisive element in the orthoplastic approach, although reconstructive algorithms may assist in decisional and planification of surgery

Open tibial fractures can be difficult to manage, with a range of factors that could affect treatment and outcome. We present a large cohort of patients, and analyse which factors have significant associations with infection outcome. Elucidation will allow clinicians to strive for treatment optimisation, and patients to be advised on likely complications. Open tibia fractures treated at a major trauma centre between 2015-2021 were included. Mean age at injury was 55.4 (range 13-102). Infection status was categorized into no infection, superficial infection, and osteomyelitis. Age, mode of injury, polytrauma, fibula status, Gustilo-Anderson (GA) classification, wound contamination, time from injury to: first procedure/definitive plastics procedure/definitive fixation, type of definitive fixation, smoking and diabetic status, and BMI, were collected. Multicollinearity was calculated, with highly correlated factors removed. Multinomial logistic regression was performed. Chi Squared testing, with Post Hoc Bonferroni correction was performed for complex categorical factors. Two hundred forty-four patients with open tibial fractures were included. Forty-five developed superficial infection (18.4%), and thirty-nine developed osteomyelitis (16.0%). Polytrauma, fibula status, and type of definitive fixation were excluded from the multivariate model due to strong multicollinearity with other variables. With reference to the non-infected outcome; superficial infection patients had higher BMI (p<0.01), higher GA grade (p<0.01), osteomyelitis patients had longer time to definitive fixation (p=0.049) and time to definitive plastics procedure (p=0.013), higher GA grade (p<0.01), and positive wound contamination(p=0.015). Poc hoc analysis showed “no infection” was positively associated with GA-I (p=0.029) and GA-II (p<0.01), and negatively associated with GA-IIIC (p<0.01). Osteomyelitis was positively associated with GA-IIIc (p<0.01). This study investigated the associations between the injury and presentation factors that may affect infection outcome. The variables highlighted are the factors clinicians should give extra consideration to when treating cases, and take preventative measures to optimize treatment and mitigate infection risk

Fracture related infections (FRI) are debilitating complications of musculoskeletal trauma surgery that can result in permanent functional loss or amputation. This study aims to determine risk factors associated with FRI treatment failure, allowing clinicians to optimise them prior to treatment and identify patients at higher risk. A major trauma centre database was retrospectively reviewed over a six-year period. Of the 102 patients identified with a FRI (66 male, 36 female), 29.4% (n=30) had acute infections (onset <6 weeks post-injury), 34.3% (n=35) had an open fracture. Open fractures were classified using Gustilo-Anderson (GA) classification (type 2:n=6, type 3A:n=16, type 3B:n=10, type 3C:n=3). Patients with periprosthetic infections of the hip and knee joint, those without prior fracture fixation, soft tissue infections, diabetic foot ulcers, pressure sore infections, patients who died within one month of injury, <12 months follow-up were excluded. FRI treatment failure was defined as either infection recurrence, non-union, or amputation. Lifestyle, clinical, and intra-operative data were documented via retrospective review of medical records. Factors with a P-value of p<0.05 in univariate analysis were included in a stepwise multivariate logistic regression model. FRI treatment failure was encountered in 35.3% (n=36). The most common FRI site was the femoral shaft (16.7%; n=17), and 15.7% (n=16) presented with signs of systemic sepsis. 20.6% (n=21) had recurrent infection, 9.8% (n=10) had non-union, and 4.9% (n=5) required an amputation. The mean age at injury was 49.71 years old. Regarding cardiovascular risk factors, 37 patients were current smokers (36.3%), 31 patients were diabetics (30.4%), and 32 patients (31.4%) were obese (BMI≥30.0). Average follow-up time was 2.37 (range: 1.04-5.14) years. Risk factors for FRI treatment failure were BMI>30, GA type 3c, and implant retention. Given that FRI treatment in 35.3% (36/102) ended up in failure, clinicians need to take into account the predictive variables analysed in this study, and implement a multidisciplinary team approach to optimise these factors. This study could aid clinicians to redirect efforts to improve high risk patient management, and prompt future studies to trial adjuvant technologies for patients at higher risk of failure

Aim. Determine the incidence of surgical site infections (SSI) after intramedullary nailing (IN) of femoral and tibial diaphyseal fractures and evaluate possible risk factors. Method. Prospective observational cohort study. SSI was defined according to CDC-NHSN criteria and surveillance period for the occurrence of infection was 12 months instead of the 90 days currently recommended. Incidence was calculated as the ratio between the number of patients with SSI and total number of patients. Analysis of potential risk factors included patients-related factors (age, gender, body mass index, active foci of infection, immunosuppressive conditions, ASA score, alcohol or illicit drug abuse, smoking, polytrauma, etiology of fracture, type of fracture if closed or open, classification of fracture according to Müller AO, Tcherne classification for closed fractures, Gustilo-Anderson classification and duration of bone exposure for open fractures, previous stay in other healthcare services, use of external fixator, previous surgical manipulation at same topography of fracture, use of blood products); environmental and surgical-related factors (surgical wound classification, duration of surgery, hair removal, intraoperative contamination, antimicrobial use, presence of drains, hypothermia or hypoxia in the perioperative period, type of IN used, reaming, need for muscle or skin flap repair, use of negative pressure therapy) and microbiota-related factors (presence of preoperative colonization by Staphylococcus aureus or Acinetobacter baumannii). Results. 221 patients were included and completed the 12-month follow-up period. Incidence of SSI was 11.8% after 12-month follow-up, but would be 8.59% if used the 90-day vigilance period currently recommended. In the initial analysis by unadjusted logistic regression, following factors were associated SSI: Müller AO classification of the fracture morphology groups 2 or 3, previous use of external fixator, presence of drains, use of negative pressure therapy and need for muscle or skin flap repair. Preoperative colonization by S. aureus or A. baumannii was not associated with occurrence of infection. In the multiple logistic regression-adjusted analysis, only previous use of external fixator and need for muscle or skin flap repair remained associated with SSI. Conclusions. Incidence of SSI associated with IN for femoral and tibial diaphyseal fractures was 11.8%, but currently recommended vigilance period would be less sensitive for SSI detection after fracture fixation. Previous use of external fixators and need for muscle or skin flap repair were factors associated with occurrence of IN related infection

Background:. There are multiple risk factors regarding the outcome of open tibia fractures treated with surgical fixation. In this study we have looked at delay to debridement and HIV infection as risk factors in the outcome of open tibia fractures. Methods:. We present a prospective study of 89 patients with open tibia fractures treated with surgical fixation with a significant delay to first debridement and a high prevalence of HIV infection. Primary outcome of this study was time to union and wound infection in the first 3 months. All patients admitted in our hospital between February 2011 and October 2012 with open fractures of the tibia requiring surgical fixation were included in the study. Patients were tested for HIV infection and multiple clinical parameters were documented, including; Gustilo-Anderson classification, ASEPSIS wound score, New Injury Severity Score(NISS), comorbidities, time to 1st debridement, time to 1st dose of antibiotics, pin site score, level of contamination, level training of the surgeon, high energy injuries, time to union and socio-economic parameters. Patients were followed to union. Results:. Twenty-five (28%) of the 89 patients were HIV positive. Forty-six (52%) patients had a delay to debridement of more than 24 hours. Eight (9%) patients developed wound infection in the first 3 months. Seventeen (19%) patients had a delayed union of more than 6 months. This study was underpowered to show a relation between wound infection and the clinical parameters of our patients. A logistic regression analysis showed that grade 3 Gustilo-Anderson injuries were associated with delayed union. We did not find an association between delayed union and; – HIV status, NISS, time to 1st debridement, high energy injuries, level of contamination and time to 1st dose of antibiotics. Conclusion:. This study suggests that delay to 1st debridement and HIV status are not significant risk factors for wound infection and delayed union in patients with open tibia fractures. There was a significant association between Gustilo-Anderson grade 3 open fractures of the tibia and delayed union. We stress the importance of good clinical judgment in the surgical treatment of open tibia fractures in a setting with high rates of HIV infection and limited resources

Open fractures are uncommon in the UK sporting population, however because of their morbidity then are a significant patient group. Currently there is very little in the literature describing the epidemiology of open fracture in sport. We describe the epidemiology of sport related open fractures from one centre's adult patient population. Retrospective analysis of a prospectively collected database recording all sport related open fracture s over a 15 year period in a standard population. Over the 15 year period, there were 85 fractures in 84 patients. The mean age was 29.2 years (range 15–67). 70 (83%) were male and fourteen female (17%). The six most common sports were football (n=19, 22%), rugby (n=9, 11%), cycling (n=8, 9%), hockey (n=8, 9%); horse riding (n=6, 7%) and skiing (n=6, 7%). The top five anatomical locations were fingers phalanges, 35%; tibia-fibula 23%; foreman 14%; ankle 11% and metacarpals 5%. The mean injury severity score was 7.02. Forty five patients were grade 1; 28 patients were grade 2; 8 patients were grade 3a; and 4 were grade 3b according to the Gustilo-Anderson classification system. Seven patients (8%) required plastic surgical intervention for the treatment of these fractures. The types of flaps used were split skin graft (n=4), fasciocutaneous flaps (n=2); and adipofascial flap (n=1). We looked at the epidemiology open fractures secondary to sport in one centre over a 15 year period. Football was the most common sport (22%) and within football, the most common site was the tibia and fibula. In contrast, within the cohort a whole the majority of fractures were upper limb, with the hand being the most common site. Whilst not common in sport, when they are sustained they are frequently occur on muddy sport fields or forest tracks and must be treated appropriately. A good understanding of the range and variety of injuries commonly sustained in different sports is important for clinicians and sports therapists

One hundred and thirty-eight patients from South Africa were part of an international study aimed to determine whether the rate of healing of compound tibial fractures treated with intramedullary nails improved with recombinant human bone morphogenetic protein-2 (rhBMP-2). There were 118 men and 20 women, with a mean age of 33.3 years. According to the Gustilo-Anderson classification, there were 32 type-I, 50 type-II, 38 type-IIA and 18 type-IIIB fractures. Patients were randomised to one of three groups: the standard care (SC) group, in which 47 patients were treated with intramedullary nail fixation and soft-tissue management, the group treated with SC and 0.75 mg/ml of rhBMP-2, which comprised 50 patients, and the group treated with SC and 1.50 mg/ml of rhBMP-2, which comprised 40 patients. At 20 and 26 weeks, there was a significant difference (p < 0.027) in the rate of fracture healing in the three groups. At one year follow-up union was achieved in 30 patients (63.8%) in the SC group and in 27 patients (54%) and 30 patients (73.2%) in the two rhBMP-2 groups respectively. All patients with type-IIIB fractures developed nonunion in the SC group, but 56% in the 0.75-mg/ml rhBMP-2 group and 50% in the 1.5-mg/ml rhBMP-2 group achieved union. Secondary intervention and medical costs were reduced in patients treated with rhBMP-2

Introduction. Open tibial fractures are associated with an increased risk of infection. The infection rate increases with increasing severity and grade of fracture. Various management options available for fracture treatment are in turn associated with complications including infection. Circular fine-wire fixators cause minimal intra-operative soft tissue disruption and possibly have a better outcome and low complication rates. Objectives. To analyse the effectiveness of circular fine-wire fixators in managing open tibial fractures and to determine the incidence of complications, particularly infection associated with use of these fixators. Methods. A retrospective review of 34 open tibial fractures treated with circular fine-wire fixators [Ilizarov and Taylor Spatial Frame (TSF)] in a teaching hospital. Results. We treated 34 patients (n=34) with fine-wire fixators. An Ilizarov frame was used for 19 (56%) and TSF was used for 16 (44%) patients. Mean patient age was 47.1 years. Seventy four percent had high energy while 26% had low energy injury. Consequently 4 (12%) had grade I, 3 (9%) had grade II, 6(17%) had grade IIIA and 21(62%) had grade IIIB injury as per the Gustilo-Anderson Classification. Forteen percent of patients had proximal, 17% had mid-shaft, 67% had distal tibial fractures respectively. Average time to union was 28.9 weeks. Grade IIIB fractures healed in 29.6 weeks. Fifty percent of these patients were full weight bearing immediately after surgery. 17 required soft tissue coverage and only two developed skin graft complications. Twelve (35%) had pin-site infection treated with antibiotics. There was one case of non-union and no reported mal-union or deep infections. Conclusion. We report fewer complications with the use of fine-wire fixators. The infection rate is low and only limited to superficial tissues. Healing time is considerably reduced and patients are full weight bearing almost immediately. These devices are particularly effective in management of grade IIIB open distal tibial fractures with decreased time to union of tibia

Aims

Fracture-related infections (FRIs) are a devastating complication of fracture management. However, the impact of FRIs on mental health remains understudied. The aim of this study was a longitudinal evaluation of patients’ psychological state, and expectations for recovery comparing patients with recurrent FRI to those with primary FRI.

Methods

A prospective longitudinal study was conducted at a level 1 trauma centre from January 2020 to December 2022. In total, 56 patients treated for FRI were enrolled. The ICD-10 symptom rating (ISR) and an expectation questionnaire were assessed at five timepoints: preoperatively, one month postoperatively, and at three, six, and 12 months.

Aims

To compare results of institutional preferences with regard to treatment of soft tissues in the setting of open tibial shaft fractures.

Methods

We present a retrospective review of open tibial shaft fractures at two high-volume level 1 trauma centres with differing practices with regard to the acute management of soft tissues. Site 1 attempts acute primary closure, while site 2 prefers delayed closure/coverage. Comparisons include percentage of primary closure, number of surgical procedures until definitive closure, percentage requiring soft tissue coverage, and percentage of 90-day wound complication.

Aims

Prompt and sufficient broad-spectrum empirical antibiotic treatment is key to preventing infection following open tibial fractures. Succeeding co-administration, we dynamically assessed the time for which vancomycin and meropenem concentrations were above relevant epidemiological cut-off (ECOFF) minimal inhibitory concentrations (T > MIC) in tibial compartments for the bacteria most frequently encountered in open fractures. Low and high MIC targets were applied: 1 and 4 µg/ml for vancomycin, and 0.125 and 2 µg/ml for meropenem.

Methods

Eight pigs received a single dose of 1,000 mg vancomycin and 1,000 mg meropenem simultaneously over 100 minutes and 10 minutes, respectively. Microdialysis catheters were placed for sampling over eight hours in tibial cancellous bone, cortical bone, and adjacent subcutaneous adipose tissue. Venous blood samples were collected as references.

Aims

The study objective was to prospectively assess clinical outcomes for a pilot cohort of tibial shaft fractures treated with a new tibial nailing system that produces controlled axial interfragmentary micromotion. The hypothesis was that axial micromotion enhances fracture healing compared to static interlocking.

Methods

Patients were treated in a single level I trauma centre over a 2.5-year period. Group allocation was not randomized; both the micromotion nail and standard-of-care static locking nails (control group) were commercially available and selected at the discretion of the treating surgeons. Injury risk levels were quantified using the Nonunion Risk Determination (NURD) score. Radiological healing was assessed until 24 weeks or clinical union. Low-dose CT scans were acquired at 12 weeks and virtual mechanical testing was performed to objectively assess structural bone healing.
