Risk factors for infection in severe open tibial shaft fractures

ObjectiveTo evaluate risk factors for infection in severe open tibial shaft fractures. MethodsA secondary analysis of a multicenter prospective study investigated internal versus external fixation of severe open tibia fractures at 20 US Level I trauma centers. Adult patients, aged <65 years, with a Gustilo-Anderson Type IIIB or severe IIIA metaphyseal or diaphyseal tibia fracture were included. All fractures underwent definitive fixation with either a modern ring external fixator, intramedullary device, and/or plate. Fourteen variables previously identified as risk factors for infection were included in the analysis. Deep surgical site infection was defined as an infection treated with surgical debridement within 1 year of index surgery. ResultsThe study cohort included 430 patients. Deep surgical site infection requiring reoperation occurred in 108 (25 %) patients. The final model identified four risk factors for infection: age >40 years (OR, 2.00; 95 % CI, 1.3–3.1), Gustilo-Anderson Type IIIB (OR, 1.80; 95 % CI, 1.1–3.0), embedded wound contamination (OR, 1.69; 95 % CI, 1.1–2.7), and wound length (OR, 1.02/cm; 95 % CI, 1.0–1.05). The model performed poorly at distinguishing infected from uninfected patients (Area Under the Curve=0.57; 95 % CI, 0.51–0.63). ConclusionsSurgeons can now counsel patients with these risk factors that they are at a markedly higher risk of infection. The identification of these risk factors may direct future research aimed at mitigating the risk of deep surgical site infection in this patient population.

The Bioburden Associated with Severe Open Tibial Fracture Wounds at the Time of Definitive Closure or Coverage: The BIOBURDEN Study.

Infection is common following high-energy open tibial fractures. Understanding the wound bioburden may be critical to infection risk reduction strategies. This study was designed to identify the bioburden profile of high-energy open tibial fractures at the time of definitive wound closure or coverage and determine the relationship to subsequent deep infection. This multicenter prospective study enrolled 646 patients with high-energy open tibial fractures requiring a second debridement surgery and delayed wound closure or coverage. Wound samples were obtained at the time of definitive closure or coverage and were cultured in a central laboratory. Cultures were also subsequently obtained from patients who underwent a fracture-site reoperation. Two hundred and six (32%) of the wounds had a positive culture at the time of closure or coverage. A single genus was identified in 154 (75%) of these positive cultures and multiple genera, in 52 (25%). Gram-positive cocci (GPCs) were identified in 98 (47%) of the positive cultures. Staphylococci were identified in 64 (31%) of the cultures, and 53 (83%) of these were coagulase-negative (CONS). Enterococci were identified in 26 (13%) of the cultures. Gram-negative rods (GNRs) were identified in 100 (49%) of the cultures; the most frequent GNR genera identified were Enterobacter (39, 19%) and Pseudomonas (21, 10%). Positive cultures were subsequently obtained from 154 (50%) of 310 revision surgeries. A single genus was identified in 85 (55%) of the 154 and multiple genera, in 69. GPCs were identified in 134 (87%) of the 154 positive cultures, staphylococci were identified in 94 (61%), and GNRs were identified in 100 (65%). The bioburden in high-energy open tibial fractures at delayed closure or coverage was often characterized by pathogens of multiple genera and of genera that are nonresponsive to typically employed antibiotic prophylaxis. Awareness of the final wound bioburden might inform strategies to lower the infection rate. Prognostic Level II . See Instructions for Authors for a complete description of levels of evidence.

An evaluation of the management of severe open tibial fractures in the United Kingdom's major trauma centres

AimTo evaluate the management of patients with severe open tibial fractures at major trauma centres (MTCs) in the UK with respect to BOAST 4 guidelines. MethodsData collected by the Trauma and Audit Research Network (TARN) for all severe open tibial fractures treated at the 23 adult MTCs were evaluated. Key performance indicators (KPIs) included MTC admission under orthoplastics, administration of antibiotics within three hours of injury, initial debridement within 24 h and definitive fixation and soft tissue coverage within 72 h. Outcomes included 30-day infection rate, amputation rate and mortality rate.A score was calculated according to overall attainment of KPIs, and correlated to outcomes. ResultsFrom 2014 to 2020, 3359 adults with Gustilo-Anderson (GA) IIIB and/or IIIC fractures were admitted to MTCs. Male to female ratio was 2:1 with a mean age of 43 and 65 years respectively.There was a negative correlation between KPI score and mortality rate (r=-0.4929, p = 0.0169). Direct admission to an MTC was positively correlated with receipt of antibiotics within three hours (r = 0.5452, p = 0.0070). Joint orthoplastic plans were documented in 89 % of patients (MTC range 30–95 %). Soft tissue cover was achieved within 72 h for 48 % (MTC range 5.23–89.39 %).Patients over 65 were significantly more likely to have a delay to MTC admission and prophylactic antibiotic administration. Mortality rate in this group was 6% vs 2 % in those under 65. The older cohort were twice as likely to require an amputation. ConclusionThis is the largest cohort of open tibial injuries managed in the UK with wide variation in practice between centres demonstrated and better adherence to BOAST guidelines linked to reduced mortality in those aged 65 and over. The older cohort of patients also had higher rates of infection and amputation.It is unclear whether these poor outcomes are due to the pre-morbid physiological status of the patient or non-compliance to Standards. We present these data to highlight the need for improved adherence to Standards – the adoption of a scoring system provides a simple way to evidence this.

Immediate versus early soft tissue coverage for severe open grade III B tibia fractures: a comparative clinical study

Controversy remains regarding timing in the management of grade III-B open tibia fractures. Many authors recommend an immediate definitive soft tissue coverage within a critical period of 12 hours, yet in many patients, this may be impossible due to concomitant injuries or delayed referral. The present case series aims to compare the role of immediate versus early soft tissue coverage for severe open grade III-B tibial fractures. 20 cases of tibial fractures of were divided into two groups; 10 cases each. Immediate group (within 12 hours) and early group (3-7 days), according to the soft tissue coverage time. Strict criteria for inclusion in the first group included debridement within 12 hours of injury, no sewage or organic contamination, the presence of bleeding skin margins, and the absence of systemic illness. All 20 cases had been treated by a debridement and soft-tissue cover with a muscle pedicle or fasio-cutanous flap. Functional outcome measures included deep infection rate, stable soft tissue coverage, number of inpatient’s stays, number of surgical procedures, and union time. The mean follow-up period was 24 months. Mean inpatient time was 30 and 41 days respectively. Mean surgical procedures were 2.2 and 3.4 respectively and union time was 26 versus 34 weeks. Mean inpatient time, mean surgical procedures per time and union time were pointedly less in the immediate flap coverage group which significantly improves results concerning early union, healing time, and cost of hospitalization and rehabilitation.

Delayed Reconstruction of the Perforator Pedicle Propeller Flap after the Induced Membrane Technique for Gustilo IIIB Open Distal Tibial Fracture.

This study aimed to evaluate the safety and efficacy of delayed reconstruction of the perforator pedicle propeller flap after the induced membrane technique in the treatment of Gustilo IIIB open distal tibial fracture, and to evaluate the clinical outcome and complications of two different perforator pedicle propeller flaps.Thirty-four patients with Gustilo IIIB open distal tibial fractures treated by the induced membrane technique and delayed reconstruction of two different perforator pedicle propeller flaps from May 2017 to March 2022 were retrospectively analyzed. Patients were divided into two groups according to the different kinds of perforator pedicle propeller flaps covered. The operation required two stages. The Radiographic Union Score for Tibial fractures (RUST) was used to evaluate the healing of the tibial bone defect. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate ankle function. The complications associated with the technique were recorded.The number of serial debridements, excluding those performed during emergency and final operations, was a mean of 2.28±0.83 in the PAPF group. The PAPF group had a mean bone defect length of 6.76 ± 0.69 cm, the median healing time of 13.11 ± 0.96 months, RUST score 12.68 ± 1.63, and AOFAS score of 84.12 ± 6.38. On the other hand the PTAPF group's mean bone defect length was 6.73 ± 0.95 cm, the median healing time 12.63 ± 1.46 months, RUST score 13.73 ± 1.53 and AOFAS score 82.79 ± 5.49. There were no observed significant differences the two groups in the number of serial debridements, bone defect length, bone union time, RUST score, or AOFAS score (p>0.05). Flap size ranged from 9×6cm2 to 14×7cm2 in the PAPF group and from 9×6cm2 to 13×7cm2 in the PTAPF group. There were no severe complications such as flap-related complications or amputation. The differences in complications in the two groups were not statistically significant.In cases of severe open tibial fracture, the reconstructive method is important. When delayed reconstruction is inevitable, surgeons should first perform radical debridement, followed by vacuum sealing drainage as a bridging therapy; both PAPF and PTAPF can be considered for definitive soft tissue coverage.

Management of bone loss in acute severe open tibial fractures: a retrospective study of twenty nine cases-a treatment strategy with bone length preservation.

The present study investigated the outcomes of bone loss associated with acute open tibial fractures classified as Gustilo-Anderson classification grade III B (GIIIB) using a bone length preservation strategy. Among acute GIIIB open tibial fractures, 29 limbs of 29 patients requiring bone loss treatment were included. The reconstruction methods for bone loss were selected among the Masquelet technique (MT), bone transport (BT), acute shortening followed by gradual lengthening (ASGL), and free vascularized fibula graft (FVFG). Primary outcome measures were the rate of bone union and time to bone union. The median radiographic apparent bone gap (RABG) was 46.75mm. Bone loss was treated with ASGL only in two patients in whom it was not possible to cover large soft tissue defects by a single free latissimus dorsi (LD) myocutaneous flap (with the serratus anterior (SA) muscle). The other 27 patients underwent soft tissue reconstruction and bone loss treatment with the preservation of bone length, including the MT for 23, BT for six, and FVFG for one. The bone union rate was 75.9%, and the median time to bone union was six months. Salvage surgeries were performed on all seven patients with nonunion; all of whom eventually achieved bony union. Bone loss associated with acute GIIIB open tibial fractures were treated with "bone length preservation" if the size of the soft tissue defect was less than the size that was covered by a single LD myocutaneous flap (with the SA muscle).

Limb salvage versus primary amputation in Gustilo-Anderson IIIB and IIIC tibial fractures: a systematic review and meta-analysis.

The last systematic review on this topic was published in 2008. With advances in surgical techniques, patients with mangled extremities may now be potentially salvageable with comparable outcomes. This review aims to evaluate the outcomes of limb salvage compared to primary amputation in patients with severe open tibial fractures. A comprehensive search on PubMed, MEDLINE, Embase, Web of Science, Scopus, CENTRAL and CINAHL was performed from inception to 19 January 2022. The primary outcome was to evaluate clinical and functional outcomes. Secondary outcomes were to evaluate pain, patient preference, quality of life, and patient preferences. Methodological quality was evaluated using the MINORS criteria. Pooled estimates of relative risk (RR) and mean difference (MD) with 95% confidence interval (CI) were used as a summary statistic for dichotomous variables and continuous variables, respectively. Sixteen studies with 645 patients met inclusion criteria. The methodological quality was moderate based on the MINORS score. The majority were male. Mean age was 36.3years. There was no significant differences in the length of hospitalization (n = 8), return to work rates (n = 9), return to sport rates (n = 4) and quality of life scores (n = 4). Patients with primary amputation had a significantly lower risk of total complications (RR 0.21, 95% CI 0.08-0.53, p = 0.001) (n = 10), infections (RR 0.46, 95% CI 0.25-0.85, p = 0.01) (n = 9), and number of surgeries (MD -4.17, 95% CI -6.49 to -1.85, p = 0.0004) (n = 6). Patients with primary amputation were able to ambulate significantly earlier (MD -4.06, 95% CI -7.65 to -0.46, p = 0.03) (n = 3). Three studies found a significantly higher cost of hospitalization in limb salvage patients. Functional outcomes were similar in both groups. While patients with primary amputation had better clinical outcomes in the short-term, functional outcomes were not significantly different in both groups. Despite the heterogenicity of the results in this review, surgeons need to contextualize the decision making for their patients and incorporate these findings. III. PROSPERO CRD42022303357.

Outcomes of Conservative versus Operative Management in Fracture Shaft Tibia and Fracture Shaft Femur in Pediatric Age Group

Background: Tibia is more often involved in open fractures because of its subcutaneous location. Severe open fractures of tibia are associated with high complication rate and poor long term outcomes. 70% of pediatric tibial fractures are isolated injuries and approximately 30% of pediatric shaft tibia fractures are associated with fibula fracture. AIM: The aim is to study clinical and radiological outcomes of patient with tibial and femoral fractures, who are treated with closed reduction and internal fixation with nailing versus treated conservatively by casting. Material and method: 40 cases with femur or tibia fractures treated with nailing and conservatively between 1st January 2022 to 30thNovember 2022 at rural medical college, loni a rural tertiary care hospital was analyzed retrospectively out of which 16 patients treated conservatively and 4 patients underwent operative management for tibia fractures while 16 patients were treated operatively and 4 patients treated conservatively for femur fractures. Results: Total 40 patients of shaft femur and shaft tibia fractures were treated conservatively with cast application and Closed reduction and internal fixation by elastic nailing. In comparision for simple transverse fracture, we can conclude that in most patients fracture can be treated conservatively to minimize soft tissue damage but only in unacceptable criteria for conservative management we can opt for minimally invasive procedure like TENS nailing. Conclusion: Immobilization time is shorter in surgical group but we have started mobilizing with cast application. It is the only advantage of surgical management which has been given in conservatively managed patients. Outcomes after 3 months.

Variation in timely surgery for severe open tibial fractures by time and place of presentation in England from 2012 to 2019 : a cohort study using data collected nationally by the Trauma Audit and Research Network.

Several studies have reported that patients presenting during the evening or weekend have poorer quality healthcare. Our objective was to examine how timely surgery for patients with severe open tibial fracture varies by day and time of presentation and by type of hospital. This cohort study included patients with severe open tibial fractures from the Trauma Audit and Research Network (TARN). Provision of prompt surgery (debridement within 12 hours and soft-tissue coverage in 72 hours) was examined, using multivariate logistic regression to derive adjusted risk ratios (RRs). Time was categorized into three eight-hour intervals for each day of the week. The models were adjusted for treatment in a major trauma centre (MTC), sex, age, year of presentation, injury severity score, injury mechanism, and number of operations each patient received. We studied 8,258 patients from 175 hospitals. Patients presenting during the day (08:00 to 15:59; risk ratio (RR) 1.11, 95% confidence interval (CI) 1.02 to 1.20) were more likely to receive debridement within 12 hours, and patients presenting at night (16:00 to 23:59; RR 0.56, 95% CI 0.51 to 0.62) were less likely to achieve the target; triage to a MTC had no effect. Day of presentation was associated with soft-tissue coverage within 72 hours; patients presenting on a Thursday or Friday being less likely to receive this surgery within 72 hours (Thursday RR 0.88, 95% CI 0.81 to 0.97; Friday RR 0.89, 95% CI 0.81 to 0.98), and the standard less likely to be achieved for those treated in 'non-MTC' hospitals (RR 0.76, 95% CI 0.70 to 0.82). Variations in care were observed for timely surgery for severe open tibial fractures with debridement surgery affected by time of presentation and soft-tissue coverage affected by day of presentation and type of hospital. The variation is unwarranted and highlights that there are opportunities to substantially improve the delivery and quality of care for patients with severe open tibial fracture.Cite this article: Bone Jt Open2022;3(12):941-952.

Outcome of Soft Tissue Coverage in Open Tibia Fractures with Non-Microvascular Flap at a Tertiary Care Hospital

Background: Open tibia fractures are high energy injuries often associated with large soft defects, extensive soft tissue stripping and contamination requiring multiple debridement procedures. Collective ortho-plastic approach helps us achieve proper debridement, adequate fixation and early soft tissue coverage. Due to fairly high incidence of failure, steep learning curve, time consuming procedure and the cost of treatment for those tedious free flaps, non-microvascular flaps are being preferred to cover the soft tissue defects or exposed hardware in open tibia fractures.&#x0D; Materials and Methods: A prospective study was carried out in 19 patients to assess the outcome of soft tissue coverage in open tibia fractures with non-microvascular flap. Out of these patients, 6 patients were treated with medial gastrocnemius flap, 5 patients with medial hemi-soleus, 5 patients with reverse sural fasciocutaneous flap, and 3 patients with local rotational random flaps. Outcome measures included bony union, deep surgical infection and flap failure.&#x0D; Results: 84% patients were male whereas 16% patients were female. Road traffic accident was the major cause of the defect among the patients (74%). Complications in the form of deep infection (10%), non-union (21%), delayed union (10%) and marginal flap necrosis (21%) were observed.&#x0D; Conclusion: In our study, early soft tissue coverage with appropriate non-microvascular flaps in management of severe open fractures of tibia was associated with more favourable outcomes.

Modern External Ring Fixation Versus Internal Fixation for Treatment of Severe Open Tibial Fractures: A Randomized Clinical Trial (FIXIT Study).

Modern external ring fixation has been hypothesized to reduce complications requiring hospital readmission compared with internal fixation when treating patients with high-energy open tibial shaft fractures. In this study, the 1-year probability of a major limb complication was compared between external and internal fixation of severe open tibial fractures. This multicenter randomized clinical trial included patients 18 to 64 years of age with severe open tibial shaft fractures randomly assigned to either modern external ring fixation (n = 127) or internal fixation (n = 133). The primary outcome was a major limb complication within 365 days after randomization; these complications included amputation, infection, a soft-tissue problem, nonunion, malunion, and a loss of reduction/implant failure. Of 260 randomized patients, 254 were included in the final analysis. Their mean age (standard deviation) was 39 (13) years; 214 (84%) were men. The probability of at least 1 major limb complication was higher for external fixation (62.1% [95% confidence interval (CI): 53.4% to 70.8%]) than internal fixation (43.7% [95% CI: 35.5% to 52.9%]), with a risk difference of 18.4% (95% CI: 5.8% to 30.4%); p = 0.005). The most notable difference was in loss of reduction/implant failure, the rate of which was higher for external fixation (risk difference: 14.4% [95% CI: 7.0% to 21.6%]; p = 0.002). There was no appreciable difference in the probability of deep infection between external fixation (26.1%) and internal fixation (29.7%) (risk difference: -3.5% [95% CI: -14.8% to 7.8%]; p = 0.54). There were also no appreciable differences in the probabilities of amputation, nonunion, soft-tissue problems, malunion, or fracture healing between the groups. These results argue against routine use of modern external ring fixation for the treatment of these severe open tibial fractures. Therapeutic Level I.

Efficacy of Staged Surgery in the Treatment of Open Tibial Fractures with Severe Soft Tissue Injury and Bone Defect.

PurposeWe aimed to report the clinical and radiological outcomes of staged surgery using the acute induced membrane technique with an antibiotic-impregnated cement spacer (ACS) and soft-tissue reconstructive surgery and to identify factors affecting clinical outcomes.Materials and MethodsThirty-two patients with severe open tibia fractures were treated via staged surgery from January 2014 to December 2019 and followed up for ≥1 year. In the first surgery, an ACS was inserted into the bone defect site along with debridement and irrigation and was temporarily fixed in place with an external fixator. The internal fixator was placed, and flap surgery and cement spacer changes were performed during the next surgery. In the third surgery, an autogenous bone graft was performed. Radiologic and functional results were investigated according to the Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria, and factors affecting the ASAMI score were analyzed.ResultsThe average bone defect width was 43.9 mm, and the size of soft-tissue defect was 79.3 cm2 . Bone union was achieved in all cases except one and required 9.4 months on average. Complications occurred in 10 cases (31.2%). Good or better clinical effects, in terms of ASAMI radiologic and functional scores, were observed in 29 and 24 cases, respectively. Complications and additional surgery were common factors affecting the two scores.ConclusionStaged surgery using the acute induced membrane technique and soft-tissue reconstructive surgery is an efficacious treatment for open tibial fractures with bone defects.

Strategies and outcomes in severe open tibial shaft fractures at a major trauma center: A large retrospective case-series.

BACKGROUNDSevere open tibia fractures are challenging to treat with a lack of published clear management strategies. Our aim was to provide an overview of the largest single-center experience in the literature, with minimum 1-year follow-up, of adult type 3 open tibial shaft fractures at Cambridge University Hospitals (a United Kingdom major trauma center). We sought to define patient characteristics and our main outcome measures were infection, union and re-fracture.AIMTo retrospectively define patient and injury characteristics, present our surgical methods and analyze our outcomes–namely infection, union and re-fracture rates.METHODSConsecutive series of 74 patients with 75 open tibial fractures treated between 2014 and 2020 (26 classified as Gustilo-Anderson 3A, 47 were 3B and two were 3C). Nine patients underwent intramedullary nailing (IMN), 61 underwent Taylor spatial frame (TSF) fixation and 5 were treated with Masquelet technique (IMN and subsequent bone grafting).RESULTSMean follow-up was 16 mo (IMN) and 25 mo (TSF). We had an infection rate of 6.7% (5), non-union rate of 4% (3) and re-fracture rate of 2.7% (2). Average time to union was 22 wk for IMN and 38.6 wk for TSF. Thirty-three cases had a bone defect with a mean of 5.4 cm (2-11). Patient age, sex, diabetes, smoking status or injury severity did not have a significant effect on union time with either fixation method. Our limb salvage rate was 98.7%.CONCLUSIONGrade 1 to 3A injuries can effectively be treated with reamed or unreamed IMN. Grade 3B/C injuries are best treated by circular external fixators as they provide good, reproducible outcomes and allow large bone defects to be addressed via distraction osteogenesis.

Is lower limb salvage worthwhile after severe open tibial fractures in a developing country? An analysis of surgical outcomes, quality of life and cost implications.

Open tibial fractures are rare and difficult-to-treat injuries because of the involvement of bony, skin and neuromuscular injury along with co-morbidities. Often, during the management of very severe cases these injuries, the question arises, should we amputate or salvage the limb? This question has been explored previously in civilian and military contexts in the US and UK but remains unstudied in the alternative sociocultural and economic context of the developing world. We studied 78 adult patients with severe open tibial fracture that presented to our institution, a Level 1 trauma center in India, from February 2018 to June 2019. 20 patients underwent above-knee amputation (AKA), 16 underwent below-knee amputation (BKA), and 42 underwent limb salvage. We assessed injury severity using [our institution's] Open Injury Severity Score (GHOISS), which has separate sub-scores for bony injury, skin injury, neuromuscular injury and co-morbidities, and patients were only included with GHOISS > 13. We assessed functional outcome measures as well as economic costs as primary cost levied by our institution and other secondary costs. Salvage (LEFS: mean=51, SF-12 PCS: mean=48, SF-12 MCS: mean=49) provided better outcomes to BKA (LEFS: mean=39, p=0.005, SF-12 PCS: mean=40, p=0.003, SF-12 MCS: mean=43, p=0.052) and AKA (LEFS: mean=31, p<0.001, SF-12 PCS: mean=34, p<0.001, SF-12 MCS: mean=43, p=0.043). Primary costs were higher for limb salvage (index: mean=$3100, total: mean=$4400) than both BKA (index: mean=$2500, p=0.012, total: mean=$2600, p<0.001) and AKA (index: mean=$2800, p=0.020, total: mean=$3200, p<0.001). Secondary costs were higher for limb salvage than both BKA and AKA (p<0.001). Patients who underwent salvage were more likely to return to work at 36 months post-injury compared to below-knee amputees (adjusted OR=0.11, p=0.010). Limb salvage results in better functional outcomes compared with amputation at a higher upfront cost but a likely lower lifetime cost. Unlike other literature on the topic, amputation carries a heavy mental and physical toll in India, likely due to sociocultural differences and stigma. Amputation is a difficult decision for patients to accept and results in poorer outcomes; therefore, we believe that limbs should be aggressively salvaged in our developing country.

Early injection of autologous bone marrow concentrates decreases infection risk and improves healing of acute severe open tibial fractures

IntroductionOpen fractures are at risk of nonunion; surgeons are reluctant to propose early standard bone grafting after open fractures, preferring to wait in order to adequately assess the facture status of infection. Bone marrow contains mesenchymal stem cells (MSCs) and granulocyte and macrophage precursors identified in vitro as colony forming units-granulocyte macrophage (CFU-GM), both of which have a prophylactic action against infection. We therefore tested the hypothesis that early injection of bone marrow concentrate would be useful in these fractures. MethodsWe evaluated a series of 231 patients who had received early percutaneous implantation of bone marrow concentrate (BMC) to treat open fractures (with gap less than 10 mm) that were Gustilo-Anderson Type II or III. The results were compared with those of 67 control (no early graft) patients and with those of 76 patients treated with an early, standard of care, iliac bone graft. All patients were treated with external fixation and were considered to have an aseptic fracture at the time of early grafting, but the actual status of infection was re-assessed at the time of grafting by histology and/or analysis of the aspirate. The bone marrow graft contained after concentration 49,758 ± 21,642 CFU-GM-derived colonies/cc and 9400 ± 1435 MSCs/cc which represents an important increase compared to the level of CFU-GM cells and MSCs present in a standard auto-graft. Healing was evaluated at 9 months. ResultsThe rate of unsuspected infections was higher than 15% in the 3 groups. Bone union and removal of external fixation was achieved at 9 months by 50.7% of patients in the Control Group, by 86.8% of patients in the group with a standard bone graft, and by 87.4% of patients in the bone marrow group. A 90% risk reduction (p = 0.005) in the need for an invasive standard bone graft to treat a nonunion and in the risk of infection was observed when bone marrow was proposed as early injection to the treatment of type II or type-III tibial fractures. ConclusionBone marrow concentrate for early grafting in open fractures with limited gap was efficient for healing while decreasing infection.

The Impact of Inadequate Soft-tissue Coverage following Severe Open Tibia Fractures in Tanzania.

Background:Managing lower extremity fractures complicated by large soft-tissue defects is challenging for surgeons in low- and middle-income countries, and long-term quality of life (QOL) for these patients is unclear.Methods:We examined QOL, surgical complications, and longitudinal outcomes in 10 patients with Gustilo-Anderson Classification Type IIIB open tibia fractures seen at an orthopedic institute in Tanzania, from December 2015 to March 2017. Patients completed follow-up at 2-, 6-, 12-, 26-, and 52-week time points, and returned for qualitative interviews at 2.5 years. The primary outcome was QOL, as measured using EuroQoL-5D scores and qualitative semi-structured interview responses. The secondary outcome was rate of complication, as defined by reoperation for deep infection or nonunion.Results:Ten patients enrolled in the study and 7 completed 1-year follow-up. All fractures were caused by road traffic accidents and treated by external fixation. No patients received initial soft-tissue (flap) coverage of the wound. All patients developed an infected nonunion. No patients returned to work at 6 weeks, 3 months, or 6 months. EQ-5D index scores at 1 year were poor (0.71 ± 0.09). Interview themes included ongoing medical complications, loss of employment, reduced income, and difficulty with activities of daily living.Conclusions:Patients in low- and middle-income countries with IIIB open tibia fractures not treated with appropriate soft-tissue coverage experience poor QOL, high complication rates, and severe socioeconomic effects as a result of their injuries. These findings illustrate the need for resources and training to build capacity for extremity soft-tissue reconstruction in LMICs.

Time to intravenous antibiotic administration (TIbiA) in severe open tibial fractures: Impact of change to national guidance

IntroductionSevere open tibial fractures are limb-threatening injuries. Outcomes depend on a complex interplay of patient, injury and treatment factors. 2009 guidelines from the British Orthopaedic Association (BOA) and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) recommend prophylactic intravenous antibiotic administration within three hours of injury. More recent National Institute for Health and Care Excellence (NICE) 2016 guidelines recommend pre-hospital antibiotic administration where possible. This study aimed to analyse the impact of time to antibiotics on development of deep infection. MethodsAdult acute Gustilo-Anderson 3B open tibial fractures managed at a single UK Major Trauma Centre were reviewed retrospectively over a three-year period, including a period before and after the regional ambulance service introduced a policy of administering pre-hospital intravenous antibiotics to open fractures in 2016. Development of deep infection was recorded as the primary outcome measure. Complete case regression analysis was performed. Time was assessed as a continuous variable and as thresholds with antibiotics received within one or three hours of injury. Results156 patients with 159 fractures were included. Following introduction of new guidance in 2016, median time to antibiotics decreased from 180 to 160 min and more patients received pre-hospital antibiotics (2% vs. 33%). Overall, 7.5% developed deep infection (n = 12) within a median follow-up of 26 months. Logistic regression found no relationship between any independent variable, including time to antibiotic administration, and development of deep infection. ConclusionsThere are a variety of factors identified in the literature and in national policies and treatment guidelines as potentially modifiable to reduce the risk of deep infection following open fractures. In this study, time to antibiotic administration was not associated with the risk of developing deep infection. The results of this study demonstrate a low infection rate, which may be due to expedient expert care delivered by a dedicated orthoplastic service in line with national guidance where achievable.

Single-stage "Fix and Flap" gives Good Outcomes in Grade 3B/C Open Tibial Fractures: A Prospective Study.

Introduction:Grade 3B/C open tibial fractures with grossly contaminated degloving injuries have poor outcomes, with or without vascular injuries. Treatment decision oscillates between limb salvage and amputation. The standard protocol of repeated debridement and delayed wound cover is a challenge in developing countries due to overcrowded emergencies and limited operating room availability. We present results of our modified protocol involving primary stabilisation with external fixation and immediate wound cover as an aggressive modality of treatment.Material and Methods:Thirty-three patients with severe open tibial shaft fractures were managed using a standardised protocol of emergent debridement, external fixation and immediate wound cover with free distant/local rotational muscle flaps and fasciocutaneous flaps, and with vascular repair in Grade 3C fractures. Intra-articular fractures were excluded. Patients were followed for a minimum of three years, with an assessment of clinical, radiological and functional outcomes.Results:Wound cover was achieved with 24 distant free muscle flaps, four local rotational muscle flaps and five fasciocutaneous flaps. All fractures united with an average time to union of 40.3 weeks (16-88). Fifteen patients (45.4%) underwent only a single major surgery using primary definitive external fixation. Deep infection was seen in four patients (12.1%). Nineteen patients had excellent to good outcomes, six were fair, and eight were poor.Conclusion:“Fix and Flap” in the same sitting, using immediate wound cover and external fixation, has given good results in our hands despite the delayed presentation, the neurovascular deficit and the degloving injury. This may be a better management strategy in overcrowded tertiary care centres of developing countries, with a single surgical procedure in almost half the cases.

Reconstruction of tibial bone defect in new age using the old age Papineau technique: A case series.

IntroductionDespite advances in treatment, chronic osteomyelitis and infected nonunion after trauma remain a challenge to the orthopaedic field. The Papineau technique, firstly described in 1973, is an alternative to treat such conditions in hospitals where microsurgery is not available, making closure of defect using flap is not feasible. We described our experience in treating patients with chronic osteomyelitis and infected non-union of tibial fractures using the Papineau technique.MethodsWe reviewed the records of patients with severe open tibial fractures with bone defects who were treated using the Papineau technique at Cipto Mangunkusumo Hospital, Jakarta, Indonesia during the period of January 2017 to August 2019. Those with diabetes mellitus, severe liver disease, or malignancies were excluded. All surgical procedures were performed by one senior orthopedic surgeon.ResultsA total of four subjects were enrolled in this study. All subjects were male, with a mean age of 29 ± 6.16 years of age. The mean time to granulation tissue was 21.5 ± 1.29 days, and the mean time to union was 6 ± 0 months. There were no complications.ConclusionsThe Papineau technique may provide successful eradication of infection, reconstruction of bone defect, and soft-tissue closure. In addition, this technique is feasible and safe, and it could be performed in small healthcare centres.
