Factors affecting early antibiotic delivery in open tibial shaft fractures.

INTRODUCTION: The incidence of infection in open tibial shaft injuries varies with the severity of the injury with rates ranging from roughly 2% for Gustilo-Anderson type I to nearly 43% for type IIIB fractures. As with all fractures, timely antibiotics administration in the emergency department (ED) is an essential component of fracture management and infection prevention. This study identifies factors associated with the expedient administration of antibiotics for open tibial shaft fractures. METHODS: This retrospective study identified patients treated for open tibial shaft fractures at an academic level 1 trauma center between 2015 and 2021. Open fractures were identified by reviewing patient charts. We used chart reviews to gather demographics, fracture characteristics, postoperative outcomes, trauma activation, and time to antibiotic order, delivery, and operating room. Univariate analysis was used to compare patients who received antibiotics within 1 h of ED presentation to those who did not. Multivariate analysis was performed to investigate factors associated with faster delivery of antibiotics. RESULTS: Among 70 ED patients with open tibial shaft fractures, 39 (56%) received early administration of antibiotics. Arrival at the ED via emergency medical service (EMS) as opposed to walking in (98% vs. 74%, p = 0.01) and trauma activation (90% vs. 52%, p < 0.001) were significantly more common in the early administration group than the late group. The early group had shorter intervals between antibiotic order and delivery (0.02 h vs. 0.35 h, p = 0.007). Multivariate analysis suggested that trauma activation, EMS arrival, and arrival during non-overnight shifts were independent predictors of a shorter time to antibiotic administration (odds ratios 11.9, 30.7, and 5.4, p = 0.001, 0.016, and 0.013, respectively). DISCUSSION: Earlier antibiotic delivery is associated with non-overnight arrival at the ED, arrival via EMS, and a coordinated trauma activation. Our findings indicate that in cases where administering antibiotics is critical to achieving positive outcomes, it is advisable to initiate a coordinated trauma response. Furthermore, hospital personnel should be attentive to the need for rapid administration of antibiotics to patients with open fractures who arrive via walk-in or during late-night hours.

Docking site interventions following bone transport using external fixation: a systematic review of the literature.

PURPOSE: Although bone transport is a well-recognised technique to address segmental bone defects, optimal management of docking sites is not absolutely determined. Some surgeons routinely intervene in all cases, and others prefer to observe and intervene only if spontaneous union does not occur. Primary aim of the study was to compare rates of docking site union between patients who underwent routine docking site intervention and those who did not. METHODS: A systematic literature review using the keywords "bone transport", "docking", "tibia", and "femur" was performed in PubMed using PRISMA guidelines. Studies published in English from January 2000 to August 2022 were included and assessed independently by two reviewers. Pooled analysis was undertaken dividing patients into two groups: those managed by routine intervention and those initially observed. RESULTS: Twenty-three clinical studies met the eligibility criteria for pooled analysis, including 1153 patients, 407 in the routine intervention and 746 in the observed group. The rate of union after initial treatment was 90% in the routine intervention group and 66% in the observed group (p < 0.0001). Overall union rates at the end of treatment were similar at 99% in both groups. Patients in the observed group required an average of 2.2 procedures to achieve union overall compared with 3.8 in the routine intervention group. Time in frame was similar between groups. CONCLUSION: Based on the current literature, routine docking site interventions cannot be recommended, since this may lead to unnecessary interventions in two thirds of patients. Timely selective intervention in those at high risk or after a defined period of observation would appear to be a logical approach.

[Trauma of the midface : Symptoms, diagnostics and treatment]. / Trauma des Mittelgesichts : Symptomatik, Diagnostik und Therapie.

Midface fractures present a clinical challenge in otorhinolaryngology due to their often complex injury pattern and nonspecific symptoms. Precise diagnostics, including differentiated imaging procedures, are required. Interdisciplinary consultation between otorhinolaryngology, maxillofacial surgery, neurosurgery, and ophthalmology is often necessary. When selecting radiographic modalities, radiation hygiene should be taken into account. Sonography provides a radiation-free imaging alternative for fractures of the nasal framework and anterior wall of the frontal sinus. The goal of treatment is to achieve stable and symmetrical reconstruction. Depending on the injury pattern, different osteosynthesis materials, individual access routes, and various surgical procedures can be used. In clinical practice, the management of midface fractures requires a multidisciplinary, flexible, and pragmatic approach based on the fracture pattern and clinical experience.

Optimising the Orthopaedic Trauma Society Open Fracture Classification system: a proposal for modification in the context of high civilian gunshot fractures.

OBJECTIVES: Uniformly classifying long bone open fractures is challenging. The purpose of this study was to propose a modified Orthopaedic Trauma Society (OTS) Open Fracture Classification System, developed in a setting with a high incidence of civilian gunshot fractures. METHODS: From our prospectively collected database, we identified all patients with open tibia and femur fractures treated with intramedullary nailing over a 4 year period. All open fractures were retrospectively reclassified from the Gustilo-Anderson Classification system to the OTS Open Fracture Classification System. RESULTS: One hundred and thirty-seven cases were identified. Ninety per cent of subjects were males. Their mean age was 34 years. The most common mechanism of injury was low-velocity civilian gunshot wounds (GSW) in 54.7% of cases. Soft tissue management was primary closure in 23.4% and soft tissue reconstruction in 24.1%. In 52.6% of cases (these all being secondary to civilian GSW), soft tissue management was healing via secondary intention. This is not included as a soft tissue management option in the OTS classification system. Fracture reclassification using the OTS Open Fracture Classification System was only possible in 47.5% of cases (Simple in 23.4%, Complex B in 24.1%). CONCLUSION: We conclude that the OTS Open Fracture Classification System is not inclusive of all open tibia and femur fractures as it does not cater for gunshot fractures. We propose a modification as follows: alter 'wound debridement' to 'appropriate wound care' and to subcategorise 'Simple' into type A and B: healing via secondary intention and primary closure, respectively.

Predictors for infection severity for open tibial fractures: major trauma centre perspective.

INTRODUCTION: Open diaphyseal tibial fractures are the most common long-bone fractures and require a rapid approach to prevent devastating complications. Current literature reports the outcomes of open tibial fractures. However, there is no robust, up-to-date research on the predictive indicators of infection severity in a large open tibial fracture patient cohort. This study investigated the predictive factors of superficial infections and osteomyelitis in open tibial fractures. MATERIALS AND METHODS: A retrospective analysis of the tibial fracture database was carried out from 2014 to 2020. Criteria for inclusion was any tibial fracture including tibial plateau, shaft, pilon or ankle, with an open wound at the fracture site. Exclusion criteria included patients with a follow-up period of less than 12 months and who are deceased. A total of 235 patients were included in our study, of which 154 (65.6%), 42 (17.9%), and 39 (16.6%) developed no infection, superficial infection, or osteomyelitis, respectively. Patient demographics, injury characteristics, fracture characteristics, infection status and management details were collected for all patients. RESULTS: On multivariate modelling, patients with BMI > 30 (OR = 2.078, 95%CI [1.145-6.317], p = 0.025), Gustilo-Anderson (GA) type III (OR = 6.120, 95%CI [1.995-18.767], p = 0.001), longer time to soft tissue cover (p = 0.006) were more likely to develop a superficial infection, and patients with wound contamination (OR = 3.152, 95%CI [1.079-9.207], p = 0.036), GA-3 (OR = 3.387,95%CI [1.103-10.405], p = 0.026), longer to soft tissue cover (p = 0.007) were more likely to develop osteomyelitis. Univariate analysis also determined that risk factors for superficial infection were: BMI > 35 (OR = 6.107, 95%CI [2.283-16.332], p = 0.003) and wound contamination (OR = 2.249, 95%CI [1.015-5.135], p = 0.047); whilst currently smoking (OR = 2.298, 95%CI [1.087-4.856], p = 0.025), polytrauma (OR = 3.212, 95%CI [1.556-6.629], p = 0.001), longer time to definitive fixation (p = 0.023) were for osteomyelitis. However, none of these reached significance in multivariate analysis. CONCLUSION: Higher GA classification is a significant risk factor for developing superficial infection and osteomyelitis, with a stronger association with osteomyelitis, especially GA 3C fractures. Predictors for superficial infection included BMI and time to soft tissue closure. Time to definitive fixation, time to soft tissue closure, and wound contamination were associated with osteomyelitis.

A major trauma centre experience with gentamicin-coated tibial intramedullary nails (ETN PROtect™) in acute primary open fracture fixation and complex revision surgery.

PURPOSE: Fracture-related infections (FRI) following intramedullary nailing for tibial shaft fractures remain challenging to treat with associated high patient morbidity and health care costs. Recently, antibiotic-coated nails have been introduced as a strategy to reduce implant related infection rates in high-risk patients. We present the largest single-centre case series on ETN PROtect® outcomes reporting on fracture union, infection rates and treatment complications. METHODS: Fifty-six adult patients underwent surgery with ETN PROtect® between 01/09/17 and 31/12/20. Indications consisted of acute open fractures and complex revision cases (previous FRI, non-union surgery and re-fracture) with a mean of three prior surgical interventions. We report on patient demographics, union rates and deep infection. Minimum follow-up was one year. RESULTS: One (1.8%) patient developed a deep surgical infection and associated non-union requiring further surgery. In addition, we identified three cases (5.4%) of aseptic non-union following facture treatment with ETN PROtect®. Of the five patients who underwent staged complex revision surgery for established FRI with ETN PROtect®, all had treatment failure with ongoing symptoms of deep infection requiring implant removal and further treatment. CONCLUSION: Use of the ETN PROtect® nail in high-risk patients (open fractures and those initially treated with external fixation) and in those patients with aseptic non-unions, demonstrates promising outcomes in the prevention of implant-related infection. In our limited series we have failed to observe any benefit over uncoated nails, when used in treating cases of previously established FRI/osteomyelitis and would therefore advise caution in their use, especially in view of the high cost.

Standardising the management of open extremity fractures: a scoping review of national guidelines.

INTRODUCTION: Open extremity fractures can be life-changing events. Clinical guidelines on the management of these injuries aim to standardise the care of patients by presenting evidence-based recommendations. We performed a scoping systematic review to identify all national clinical practice guidelines published to date. MATERIALS AND METHODS: A PRISMA-compliant scoping systematic review was designed to identify all national or federal guidelines for the management of open fractures, with no limitations for language or publication date. EMBASE and MEDLINE database were searched. Article screening and full-text review was performed in a blinded fashion in parallel by two authors. RESULTS: Following elimination of duplicates, 376 individual publications were identified and reviewed. In total, 12 clinical guidelines were identified, authored by groups in the UK, USA, the Netherlands, Finland, and Malawi. Two of these focused exclusively on antibiotic prophylaxis and one on combat-related injuries, with the remaining nine presented wide-scope recommendations with significant content overlap. DISCUSSION: Clinical practice guidelines serve clinicians in providing evidence-based and cost-effective care. We only identified one open fractures guideline developed in a low- or middle-income country, from Malawi. Even though the development of these guidelines can be time and resource intensive, the benefits may outweigh the costs by standardising the care offered to patients in different healthcare settings. International collaboration may be an alternative for adapting guidelines to match local resources and healthcare systems for use across national borders.

Outcomes of free vascularised fibular graft reconstruction in upper limb trauma-a systematic review.

PURPOSE: To evaluate existing literature describing the use of free fibular flaps in upper extremity trauma and summarise flap outcomes. Secondary objectives are to evaluate patient demographics and flap characteristics. METHODS: EMBASE, PubMed, MEDLINE and the Cochrane Database were searched for eligible studies published from 1975 to January 2019. Primary outcome measures collected were rate of union, graft survival rate, and complication rates. Patient demographics and flap characteristics were also collected. Statistical analysis was performed using SPSS software (SPSS version 25; IBM, Chicago, USA). Pooled data were presented as mean and standard deviation or median and range. Categorical variables were assessed by chi-squared test. Quality of studies were assessed using the National Institutes of Health (NIH) Quality Assessment Tool for case series studies. RESULTS: Initial search yielded 1070 articles. A total of 25 studies (151 cases) met the inclusion criteria. Flap survival was 97% (147/151) at time of follow-up, with first union rate of 95% (142/151) and second union rate of 97% (147/151) following bone graft or further procedure. Overall complication rate was 33% (47/140). There was a statistically significant association between recipient flap site and rates of flap fracture (p = 0.049). There was no statistically significant association between flap type, evidence of infection at donor or defect site, or method of flap fixation on outcomes. CONCLUSIONS: Vascularised fibular flaps are a safe and efficacious reconstructive option for upper limb trauma. Further research is required to enable better understanding of the impact of patient and clinical factors on flap outcome measures.

Type of antibiotic but not the duration of prophylaxis correlates with rates of fracture-related infection.

PURPOSE: The issue of optimal prophylactic antibiotic administration for closed and open fracture surgeries remains controversial. The purpose of this study was to assess the role of type and duration longer than 48 h of antibiotic prophylaxis on the rates of fracture-related infection (FRI). METHODS: This is a single-center, prospective observational cohort study carried out with patients undergoing surgery for implants insertion to fracture stability. Risk estimates were calculated on the variables associated with factors for FRI and reported as a prevalence ratio (PR) with respect to the 95% confidence interval (CI). RESULTS: Overall, 132 patients were analyzed. The global rate of FRI was 15.9% (21/132), with open and closed fractures accounting for 30.5% (11/36) and 10.4% (10/96), respectively. The FRI rates in patients undergoing orthopedic surgery for fracture stabilization who received prophylactic antibiotic for up to and longer than 48 h were 8.9% and 26.4%, respectively. This difference did not reach statistical significance (prevalence ratio [PR] = 2.6, 95% confidence interval [95% CI]: 0.9-7.3. p = 0.063). CONCLUSIONS: Duration of antibiotic prophylaxis for surgical orthopedic fractures was not correlated with rates of FRI.

Filling the gap: a series of 3D-printed titanium truss cages for the management of large, lower limb bone defects in a developing country setting.

INTRODUCTION: Large segmental long bone defects are notoriously difficult to manage. Treatment is resource-intensive due to the complexity, cost, and specialized skills required. Truss designs are known for their triangular shapes organized in web configurations. This allows for maximal mechanical strength, the least mass, and a lattice that can be filled with bone graft. Using a truss cage combined with contemporary internal fixation provides immediate stability for bone ingrowth and long-term potential union. The implant is designed using virtual 3D modelling of the patient's bone defect based on a CT scan. The truss cage can be used in a staged procedure combined with Masquelet's induced membrane technique. This study aims to review the outcomes of patient-specific, locally designed 3D titanium truss cages packed with cancellous autograft in treating segmental, long bone defects in the lower limb in a developing country setting. METHODS: This retrospective series reviewed cases performed at various institutions between January 2019 and March 2022. Parameters assessed included patient demographics, size and location of the defect, time to clinical and radiological union and complications. RESULTS: Nine cases were included for review, with a mean age of 36 years (range 19-52). Defects ranged from 60 to 205 mm, and eight cases were staged procedures. Eight cases used intramedullary reamings as bone graft. Contemporary intramedullary nails were used for fixation in all cases. No peri- or post-operative complications occurred. All cases progressed to functional union. CONCLUSION: 3D-printed titanium truss cages combined with bone graft appear to be an effective treatment of large bone defects in the lower limb in a developing country setting in the short term. No complications were encountered, but longer follow-up is needed before definitive recommendations can be made. LEVEL OF EVIDENCE: Level IV (retrospective case series).

Management of open elbow fractures: experiences and outcomes from a UK major trauma center.

HYPOTHESIS AND BACKGROUND: Open fractures about the elbow are an infrequent but complex injury with limited existing literature. The aims of the study were to review the treatment strategies of open elbows fractures, functional outcome and complication rates associated with the injury, and correlate the outcome with the topography of the fracture. METHODS: Patients (n = 21) with open elbow fractures injuries over a 2-year period were analyzed. They were assessed regarding the orthoplastic characteristics of their injury as well any other associated injuries. Outcomes were assessed objectively (achievement of bony union, range of movement, infection status, need for further procedures) and subjectively (Oxford Elbow Score, EQ-5D, EQ-VAS). RESULTS: The commonest grade of open injury was grade 3 (43%). Associated orthopedic injuries were present in 62% and associated system injuries in 57%. Almost half of the patients were noted to have had a significantly increased presenting mortality risk as per Injury Severity Score assessment. Mean time to first wound débridement was 31 hours. There were no cases of deep or chronic infection. Complete bony union was noted in 85% of patients, and 48% of patients required removal of metalwork. Subgroup analysis of the cohort by fracture topography (single unipolar elbow bone injury vs. multiple elbow bony injuries) demonstrated no significant difference (P > .05) regarding rate of complication or final Oxford Elbow Score, EQ-5D or EQ-VAS. Patients with injuries that involved the distal humerus had the highest rate for further procedures (P < .05). The average Oxford Elbow Score, EQ-5D, and EQ-VAS scores for the whole cohort at final follow-up were 37.4, 0.54, and 62.18, respectively. DISCUSSION: Open elbow injuries are usually from high-energy trauma and often combined with other significant injuries. As a result, the timelines to elbow surgery were often delayed. However, this did not impact the local infection rates nor did it necessitate further surgery, but made achieving all British Orthopaedic Association Standards for Trauma targets difficult. Chronic infection was not an issue in this cohort. Subgroup analysis indicates open distal humerus fractures carry the highest risk for further procedures. This is most commonly in the form of removal of metalwork and fibrinolysis. End outcomes for patients with open elbow fractures can be positive, despite the notable presenting Injury Severity Score. A subspecialist elbow and orthoplastic approach whenever possible is advocated.

Honey dressing: a missed way for orthopaedic wound care.

PURPOSE: Orthopaedic-related wounds are critical situations calling for care to avoid deep infections and its consequences. The purpose of this study was to evaluate the efficacy of using honey for care of orthopaedic-related wounds with limited resources. PATIENTS AND METHODS: This prospective study included 50 cases with an average age of 38.18 (range 17-63) years with 38 males and 12 females. The most frequent wound location was the leg (41 patients; 82%), then the foot (six patients; 12%), and the ankle in three patients (6%). The aetiologies were open fractures (34 cases; 68%), infected tibial non-unions (nine cases; 18%), and post-operative infections (seven cases; 14%). Exposed tendon was present in three cases. Bone exposure was present in two cases. Deep infection was present in 29 cases (58%). Besides treating the primary cause, a ribbon of gauze soaked with honey was applied to the wounds after thorough saline washing. RESULTS: Wound sizes were variable. All cases showed improvement in all parameters with complete wound healing and full coverage of bone and tendons. Recurrence of deep infection occurred in three cases and treated by debridement. One case needed sequestrectomy of a small exposed tibial cortical fragment. Exposed tendon cases showed superficial necrosis which was treated by simple debridement. Initial mild itching occurred in five patients with spontaneous resolution. CONCLUSION: With treating the underlying aetiology and optimising the patient's general condition, honey was an effective, simple, and affordable method of wound care in different orthopaedic conditions even with exposed bone or tendons.

LONG-TERM RESULTS OF TREATING PATIENTS WITH OPEN FRACTURES OF LOW-LEG BONES.

OBJECTIVE: The aim: To analyse long-term results of treating patients with open fractures of low-leg bones within a specific time period and to describe concomitant problems. PATIENTS AND METHODS: Materials and methods: A retrospective study was carried out to evaluate the results of the final treatment of patients after one year and after five years. Patients were divided into two groups. Group I included 47 (61.84%) patients for whom the treatment method was changed from external fixation to internal fixation. Group II included 29 (38.16%) patients for whom the final treatment of an open fracture was performed with an external fixation device without changing the method. The study exclusion criteria were patients under 18 years old and patients with gunshot fractures of the lower leg bones. RESULTS: Results: Patient treatment included initial surgical debridement and fracture stabilization with external fixation devices. In all patients, wound healing occurred within 30 days (on average, 24 ± 4.5 days). When evaluating the treatment of patients in group I, 32 (68.09%) of them underwent a one-stage removal of an external fixation device and osteosynthesis of fragments during the first 7-10 days. In 3 (20.0%) patients, osteosynthesis was performed with an intramedullary locking nail, in 12 (80.0%) patients - with a plate. The decision to change the fixation method was made taking into account clinical and laboratory parameters. It is noted that the treatment of patients with type III open fractures of the lower leg bones according to the Gustilo-Andersen classification, provided that the method of external fixation is replaced with an internal one, gives better results compared to osteosynthesis with external fixation devices. CONCLUSION: Conclusions: Treatment of patients with high-energy injuries of the lower leg bones is a long-term process. It is possible to improve the therapy efficiency by changing the fixation method from external to internal one. In this regard, the main evaluative characteristics are such indicators as uncomplicated wound healing combined with the absence of laboratory and clinical signs of inflammation.

Orthoplastic Management of Open Midfoot Injuries: Is Functional Limb Salvage Possible?

High energy open midfoot injuries are uncommon but devastating injuries. A combination of complex fracture dislocations and soft tissue injury patterns render reconstruction challenging. The aim of this study was to assess the surgical and patient reported outcomes following orthoplastic management of open midfoot injuries in a Major Trauma Center. A retrospective review of all open midfoot fractures admitted to our unit between January 2015 and December 2016 was undertaken. Demographics, operative details, complications, additional surgeries, and patient reported outcomes in the form of EQ-5D and Enneking scores were collected. Fifteen patients were identified (13 male, mean age 39.2 years). One patient underwent amputation at initial debridement and 8 required additional debridement. Of these 8 patients, 3 had an amputation during their index admission. In the limb salvage group (11 patients), definitive soft tissue cover involved free flaps in 6 patients, split skin graft in 3 patients, and delayed primary closure in 2 patients. Definitive orthopedic treatment was internal fixation in 8 and external fixation in 3 patients. Two patients required a Masquelet procedure for bone loss. One patient had a toe amputation and 1 had a below knee amputation for deep infection. The median EQ-5D score was 66 (interquartile range 43), and the median Enneking score was 20.5 (interquartile range 9). Limb salvage following open midfoot fractures is technically possible in most cases, however this often involves multiple procedures and the outcomes are variable and difficult to predict. Patients should be carefully counseled, and amputation considered in all such cases.

Reliability of S.A.R.A. (sterilization and reimplantation autograft) technique in long bone open fractures.

The reimplantation of small or large extruded bone segments is one of the most complex clinical management scenarios in the treatment of open fractures. No consensus exists regarding the efficiency of this technique. The aim of the study was to analyse the clinical and radiological outcomes of Sterilization and Reimplantation Autograft (S.A.R.A.) technique in open fractures. Therefore, fifteen skeletally mature patients with Gustilo-Anderson -IIIB type fractures treated with autograft reimplantation, were included in this study. The sample size was divided in two groups: patients with a loss of small segments (Group A - less than 5 cm) and those with large segments (Group B - greater than 5 cm). Eight patients belonged to Group A and seven to Group B. The treatment of contaminated bone may be performed by the following protocols: saline rinse, povidone-iodine scrub and saline rinse, retain periosteum, immersion in antibiotic solution (clindamycin and gentamicin and metronidazole), washing with physiological solution, acute reimplantation in Group A or reimplantation after 21 days in Group B after a bone freezing at -80°C. The Radiographic Union Score (RUS), pain visual analogic score (VAS), patient satisfaction and return to work were assessed at a mean follow-up of 24 months. No cases of superficial or deep infection were reported at 2-year follow-up. The fractures achieved a complete union in 14 patients; one patient belonging to Group A had a malabsorption of the replanted bone. Furthermore, povidone-iodine scrub, antibiotic solution immersion, and washing with physiological solution preserved the articular surface morphology. This study suggests that reimplantation of extruded short or long segments may represent a reliable alternative to amputation in open long bone fractures. Further studies are needed to define the most efficient technique for sterilizing the bone autograft to reduce the complication rate.

Outcomes after implementation of an open fracture clinical pathway.

INTRODUCTION: Open fractures are associated with high rates of complication, morbidity and high economic costs. To improve outcomes, an open extremity fracture clinical pathway that protocolized surgical management and encouraged multidisciplinary collaboration was implemented in our institution. This study evaluates the clinical outcomes before and after the implementation of the pathway. METHODOLOGY: Retrospective review of open tibial and femur fractures covering the 2 year periods before and after pathway implementation was conducted. Patient demographics, fracture location, fixation methods and Gustilo-Anderson classification type were recorded. Primary outcomes include complications of wound infection, implant infection, delayed/non-union and flap failure occurring in a 1 year follow-up period. Secondary outcomes include length of hospital stay, time from emergency department (ED) entrance to first wound debridement, time from ED to flap coverage and total number of operations required. RESULTS: A total of 43 pre-pathway and 46 post-pathway patients were included in this study. There was a significant reduction in length of hospital stay, a 37.5% decrease from a median of 11.2 to 7 days after pathway implementation. There was also a significant decrease in the number of fractures fixed with external fixators from 47 to 26%. No significant differences were found for the other secondary variables. In a subgroup analysis of type III fractures, there was a significant decrease in length of hospital stay as well as the number of operations required. Median length of hospital stay decreased by 46.7% from 15 to 8 days and total number of operations decreased by 50% from a median of four operations to two operations. CONCLUSION: This study demonstrates that the implementation of an open extremity fracture clinical pathway significantly reduces the proportion of external fixation surgeries, length of hospital stay, and number of operations in patients with open tibial and femur fractures, without compromising complication rates.

Surgical site infection following operative treatment of open fracture: Incidence and prognostic risk factors.

Considering the high incidence of postoperative complications of open fracture, management of this injury is an intractable challenge for orthopaedist, and surgical site infection (SSI) is the devastate one. Screening for high-risk patients and target them with appropriate interventions is important in clinical practice. The aim of this study was to identify modifiable factors that were associated with SSI following operative treatment of open fractures. This retrospective, multicentre study was conducted at three hospitals. A total of 2692 patients with complete data were recruited between June 2015 and July 2018. Demographic characteristics, operation relative variables, additional comorbidities, and biochemical indexes were extracted and analysed. Receiver operating characteristic analysis was performed to detect the optimum cut-off value for some variables. Univariate and multivariate logistic analysis models were performed, respectively, to identify the independent risk factors of SSI. The overall incidence of SSI was 18.6%, with 17.0% and 1.6% for superficial and deep infection, respectively. Results of univariate and multivariate analyses showed the following: fracture type, surgical duration > 122 minutes, anaesthesia time > 130 minutes, intraoperative body temperature < 36.4°C, blood glucose (GLU) > 100 mg/dL, blood platelet (PLT) < 288 × 109 , and white blood cells (WBC) > 9.4 × 109 were independent risk factors of postoperative wound infection following operative treatment of open fractures. Six modifiable factors such as surgical duration > 122 minutes, anaesthesia time > 130 minutes, intraoperative body temperature < 36.4°C, GLU > 100 mg/dL, PLT < 288 × 109, and WBC > 9.4 × 109 play an important role in the prevention of SSI, and these factors should be optimized perioperatively.

Compliance and Related Outcomes of Prophylactic Antibiotics in Traumatic Open Fractures.

Purpose: Prophylactic antibiotic therapy is a standard of care for patients who present with open fractures due to the risk of infectious complications. This study was conducted to characterize the use of initial prophylactic antibiotic use in open fractures, guideline compliance, and its impact on care. Methods: Retrospective chart review of adult patients presenting with an open fracture to a Level 1 Trauma Center Emergency Department over a 12-month period was conducted. Results: Of the 202 patients meeting inclusion criteria, overall compliance with guideline recommendations for antibiotic prophylaxis was found to be 33.2%. The duration of prophylactic therapy was significantly longer in the noncompliant group and among those who received a secondary antibiotic (P < .05 for both comparisons). The duration of therapy was found to be significantly longer in those patients who developed an infection (P < .001). Those who developed an infection had a longer hospital length of stay (LOS) (P < .001) and intensive care unit LOS (P = .002). In addition, those who developed an infection had significantly more surgeries (P < .001) and received more red blood cell transfusions (P < .001). Correlation analysis confirmed a significant association between infection and duration of antibiotic prophylaxis (P = .02), number of surgeries (P < .0001), and number of transfusions (P < .0001). Conclusion: Guideline compliance was exceedingly low due to the extended duration of initial antibiotic therapy and did not appear to yield any clinical benefits. Infection was significantly associated with longer duration of initial prophylactic therapy and morbidity. Opportunities exist to elevate compliance with guidelines and to reevaluate prophylactic antimicrobial therapy in this setting.

Prehospital Antibiotic Prophylaxis for Open Fractures: Practicality and Safety.

OBJECTIVE: Early antibiotic administration has been associated with a significant decrease in infection following open fractures. However, antibiotics are most effective at a time when many patients are still being transported for care. There is limited evidence that antibiotics may be safely administered for open fractures when being transported by life-flight personnel. No such data exists for ground ambulance transport of patients with open fractures. The purpose of the study was to assess the safety and feasibility of prophylactic antibiotic delivery in the prehospital setting. METHODS: We performed a prospective observational study between January 1, 2014 and May 31, 2015 of all trauma patients transferred to a level 1 trauma center by a single affiliated ground ambulance transport service. If open fracture was suspected, the patient was indicated for antibiotic prophylaxis with 2 g IV Cefazolin. Exclusion criteria included penicillin allergy, higher priority patient care tasks, and remaining transport time insufficient for administration of antibiotics. The administration of antibiotics was recorded. Patient demographics, associated injuries, priority level (1 = life threatening injury, 2 = potentially life threatening injury, 3 = non-life threatening injury), and timing of transport and antibiotic administration were recorded as well. RESULTS: EMTs identified 70 patients during the study period with suspected open fractures. Eight reported penicillin allergy and were not eligible for prophylaxis. The patient's clinical status and transport time allowed for administration of antibiotic prophylaxis for 32 patients (51.6%). Total prehospital time was the only variable assessed that had a significant impact on administration of prehospital antibiotics (<30 minutes = 29% vs. >30 minutes = 66%; p < 0.001). There were no allergic reactions among patients and no needle sticks or other injuries to EMT personnel related to antibiotic administration. CONCLUSIONS: EMT personnel were able to administer prehospital antibiotic prophylaxis for a substantial portion of the identified patients without any complications for patients or providers. Given the limited training provided to EMTs prior to implementation of the antibiotic prophylaxis protocol, it is likely that further development of this initial training will lead to even higher rates of prehospital antibiotic administration for open fractures.

Masquelet Reconstruction for Posttraumatic Segmental Bone Defects in the Forearm.

PURPOSE: The Masquelet technique is a procedure increasingly utilized for addressing segmental bone defects. The technique involves staged procedures consisting of bone debridement and temporary spacer placement to induce membrane formation, followed by delayed bone grafting. This report summarizes our center's experience with the Masquelet technique to reconstruct bone loss exclusively in the forearm. METHODS: We reviewed all cases in which the Masquelet technique was used to reconstruct segmental bone defects in the forearm resulting from acute trauma or nonunion, with or without infection, between 2014 and 2017 at a level-1 trauma center. Injury mechanism, prior surgeries, extent of bone defect, and demographic data were collected. Union was assessed along with treatment-related complications or reoperations. RESULTS: We identified 9 patients with segmental bony defects in the forearm treated with the Masquelet technique. Among this cohort, 5 patients had bone defects associated with acute open fractures and 4 patients presented with nonunion (1 atrophic and 3 infected nonunions). The median bony defect was 4.7 cm (range, 1.7-5.4 cm) at the time of grafting. Second stage grafting was performed with Reamer Irrigator Aspirator autograft from the femur in 8 patients and iliac crest bone cancellous graft in 1 patient. Union was achieved in all 9 patients. Six patients achieved union by 3-month follow-up, 2 patients by 6 months, and 1 patient by 12 months. One patient required a reoperation for plate fracture prior to union treated with revision internal fixation and grafting. CONCLUSIONS: The Masquelet technique effectively reconstructed traumatic and posttraumatic segmental defects in the forearm with a low incidence of complication. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.
