Evaluating fracture risk in acute ankle sprains: Any news since the Ottawa Ankle Rules? A systematic review

Diagnostic value of FAST ankle ultrasound compared to standard radiography for fracture detection in the emergency department by non-radiologist physicians: a monocentric prospective diagnostic cohort study

PURPOSE

The goal of this study was to assess the diagnostic value of FAST ankle ultrasound, performed by non-radiologist specialist physicians, compared to standard X-ray imaging for ankle and foot trauma in the emergency department. Additionally, we analyzed whether other variables, such as demographic characteristics of the included patients, could influence fracture detection with the diagnostic tools used.

METHODS

A non-randomized monocentric prospective diagnostic cohort study was conducted on 143 patients.

RESULTS

Ankle and foot fractures were more frequently detected by FAST ultrasound compared to standard radiography. Regarding the influence of demographic factors, age and the correlation between Body Mass Index and age significantly influenced the ability to detect fractures.

CONCLUSION

FAST ultrasound demonstrated good diagnostic value in routine clinical practice for screening purposes and could be easily applied by non-radiologist specialist physicians. Implementing this approach may reduce time and costs in patient management, thereby aiding in alleviating triage congestion in the emergency department.

MRI in Acute Ankle Sprains: Should We Be More Aggressive with Indications?

Acute ankle sprains are common sports injuries. MRI is the most accurate test for assessing the integrity and severity of ligament injuries in acute ankle sprains. However, MRI may not detect syndesmotic and hindfoot instability, and many ankle sprains are treated conservatively, questioning the value of MRI. In our practice, MRI adds value in confirming the absence or presence of ankle sprain-associated hindfoot and midfoot injuries, especially when clinical examinations are challenging, radiographs are inconclusive, and subtle instability is suspected. This article reviews and illustrates the MRI appearances of the spectrum of ankle sprains and associated hindfoot and midfoot injuries.

Radiological outcomes of bimalleolar fractures: Are timing of surgery and type of reconstruction important?

OBJECTIVE

The goal of open reduction and internal fixation (ORIF) of bimalleolar ankle fractures is to reconstitute ankle anatomy. The most commonly used radiological parameters to assess adequacy of reduction are talocrural angle (TCA), medial clear space (MCS), tibiofibular overlap (TFO) and tibiofibular clear space (TFCS). There is little research about the radiological outcomes of surgery in bimalleolar fractures. We aimed at assessing the adequacy of ORIF and the factors involved in anatomical restoration (specifically time to surgery), postoperatively and at follow-up.

METHODS

TCA, MCS, TFO and TFCS were measured in preoperative and postoperative radiographs of 107 bimalleolar ankle fractures and in 83 follow-up radiographs, accounting for a total of 297 radiographs and 1182 measurements. Preoperative radiographs were categorized according to Danis-Weber classification. For all included cases, basic demographic data, dates of radiographs and surgery, and type of fixation used were acquired. Variables associated with postoperative and follow-up total anatomical reconstitution (i.e., when the four assessed radiological parameters were normalized), normalization of each radiological parameter, and improvement in the number of normalized radiological parameters were identified through univariable Cox regression analysis.

RESULTS

In our sample, 23.8% of the ankle fractures in postoperative radiographs and 28% in follow-up radiographs achieved a complete anatomical restoration. Type C fractures (hazard ratio [HR]=0.1, 95% confidence interval [CI]=0.02-0.7, P=0.021) were associated with lower chances of total anatomical reconstitution. The use of reconstruction plates (HR=0.1, 95% CI=0.03-0.7, P=0.014) and one third tubular plates (HR=0.2, 95% CI=0.03-0.8, P=0.026) decreased the chances of improving the number of normalized radiological parameters. Waiting days until surgery impaired total anatomical reconstitution (HR=0.8, 95% CI=0.6-0.9, P=0.012) and also reduced the chances of improving the number of normalized radiological parameters (HR=0.9, 95% CI=0.9-1.0, P=0.045).

CONCLUSION

The radiological results for the treatment of bimalleolar fractures are time sensitive, and surgery should thus be performed as soon as possible, using adequate fixation materials, in order to achieve a better restoration of ankle anatomy.

Diagnostic accuracy of the Ottawa ankle rule to exclude fractures in acute ankle injuries in adults: a systematic review and meta-analysis

Background

Ankle traumas are common presenting injuries to emergency departments in Australia and worldwide. The Ottawa Ankle Rules (OAR) are a clinical decision tool to exclude ankle fractures, thereby precluding the need for radiographic imaging in patients with acute ankle injury. Previous studies support the OAR as an accurate means of excluding ankle and midfoot fractures, but have included a paediatric population, report both the ankle and mid-foot, or are greater than 5 years old. This systematic review and meta-analysis aimed to update and assess the existing evidence of the diagnostic accuracy of the Ottawa Ankle Rule (OAR) acute ankle injuries in adults.

Methods

A systematic search and screen of was performed for relevant articles dated 1992 to 2020. Prospective and retrospective studies documenting OAR outcomes by physicians to assess ankle injuries were included. Critical appraisal of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Outcomes related to psychometric data were pooled using random effects or fixed effects modelling to calculate diagnostic performance of the OAR. Between-study heterogeneity was assessed using the Higgins I2 test, with Spearman’s correlation test for threshold effect.

Results

From 254 unique studies identified in the screening process, 15 were included, involving 8560 patients from 13 countries. Sensitivity, specificity, negative likelihood ratio, positive likelihood ratio and diagnostic odds ratio were 0.91 (95% CI, 0.89 to 0.92), 0.25 (95% CI, 0.24 to 0.26), 1.47 (95% CI, 1.11 to 1.93), 0.15 (95% CI, 0.72 to 0.29) and 10.95 (95% CI, 5.14 to 23.35) respectively, with high between-study heterogeneity observed (sensitivity: I2 = 94.3%, p < 0.01; specificity: I2 = 99.2%, p < 0.01). Most studies presented with low risk of bias and concern regarding applicability following assessment against QUADAS-2 criteria.

Conclusions

Application of the OAR is highly sensitive and can correctly predict the likelihood of ankle fractures when present, however, lower specificity rates increase the likelihood of false positives. Overall, the use of the OAR tool is supported as a cost-effective method of reducing unnecessary radiographic referral, that should improve efficiency, lower medical costs and reduce waiting times.

The Comparison of Ottawa Ankle Rules and Shetty test performances in foot-ankle trauma patients visited to the emergency department

BACKGROUND

The Ottawa Ankle Rules (OARs) and Shetty test (ST), are assessment guidelines intended to minimize radiographs in patients with ankle trauma. The aim of this study is to determine and compare the effectiveness of OARs and ST in patients admitted to the emergency department (ED) with foot and ankle trauma.

METHODS

This prospective cohort study was carried out in the ED of a tertiary care teaching hospital. OARs and ST were practiced by different doctors to patients, who were admitted with foot and ankle trauma. X-ray images were analyzed by a radiologist. Accuracy measures were covered such as sensitivity, specificity, positive predictive value, negative predictive value.

RESULTS

The study was completed a total of 207 patients, after achieving the inclusion and exclusion criteria. The mean age of the patients was 33.1±16.3, and 96 (46.4%) were female. For OARs, it was determined that as sensitivity 97.22%, specificity 48.89%, positive predictive value 50.36%, negative predictive value 97.06%, positive likelihood ratio 1.9 and negative likelihood ratio 0.06. If the OARs had been used, there would have been a 32.8% reduction in the ankle X-ray system. For the ST, it was determined that as sensitivity 51.39%, specificity 85.93%, positive predictive value 66.07%, negative predictive value 76.82%, positive likelihood ratio 3.65 and negative likelihood ratio 0.57.

DISCUSSION

The OARs can be used as a screening tool, due to causing the high sensitivity in foot and ankle traumas. The ST was found to be inefficient in this study. In addition, the significant reduction in the number of X-rays with the use of OARs is another major result of the study.

Low-value injury care in the adult orthopaedic trauma population: A systematic review

OBJECTIVES

Fifteen potentially low value practices in adult orthopaedic trauma care were previously identified in a scoping review. The aim of this study was to synthesise the evidence on these practices.

METHODS

We searched four databases for systematic reviews, randomised controlled trials (RCTs), cohort studies and case series that assessed the effectiveness of selected practices. Methodological quality was evaluated using the Measurement Tool to Assess Systematic Reviews version 2 (AMSTAR-2) for systematic reviews and the Critical Appraisal Checklist for Case Series. We evaluated risk of bias with the Cochrane revised tool for RCTs and the risk of bias in non-randomised studies of interventions tool for observational studies. We summarised findings with measures of frequency and association for primary outcomes.

RESULTS

Of the 30,670 records screened, 70 studies were retained. We identified high-level evidence of lack of effectiveness or harm for routine initial imaging of ankle injury, orthosis for A0-A3 thoracolumbar burst fracture in patients <60 years of age, cast or splint immobilisation for suspected scaphoid fracture negative on MRI or confirmed fifth metacarpal neck fracture, and routine follow-up imaging for distal radius and ankles fractures. However, evidence was mostly based on studies of low methodological quality or high risk of bias.

CONCLUSION

In this review, we identified clinical practices in orthopaedic injury care which are not supported by current evidence and whose use may be questioned. In future research, we should measure their frequency, assess practice variations and evaluate root causes to identify practices that could be targeted for de-implementation.

A 20-year perspective on the Ottawa Ankle Rules: Are we still on solid footing?

ABSTRACT

The Ottawa Ankle Rules, finalized in 1995, are a clinical decision directive for the use of radiographs in patients with traumatic ankle and foot injuries. The researchers who developed the rules defined clinically insignificant ankle fractures as distal fibular or malleolar chip fractures of 3 mm or less. They concluded that at least one-third of all ankle and foot radiographs could be eliminated by using their rules, which have since been adopted as the standard of care in EDs. This article explores whether, after more than 20 years in use, the Ottawa Ankle Rules are still valid, and whether they should continue to be used or be replaced by a superior protocol.

Isolated Medial Cuneiform Fractures: A Systematic Search and Qualitative Analysis of Case Studies

BACKGROUND

Isolated medial cuneiform fracture is a rare but diagnostically challenging condition. Diagnostic delay in these cases may lead to delays in ideal treatment approaches and prolonged symptoms. An understanding of clinical presentation is needed to expedite diagnosis, facilitate decision making, and guide treatment approach.

METHODS

Case studies/series were searched in four databases until September 2019. Included studies had participants with a history of traumatic closed medial cuneiform fracture. Studies were excluded if the medial cuneiform fractures were open fractures, associated with multitrauma, or associated with dislocation/Lisfranc injury. Three blinded reviewers assessed the methodological quality of the studies, and a qualitative synthesis was performed.

RESULTS

Ten studies comprising 15 patients were identified. Mean ± SD patient age was 38.0 ± 12.8 years, with 86.7% of reported participants being men. The overall methodological quality was moderate to high, and reporting of the patient selection criteria was poor overall. The most commonly reported clinical symptoms were localized tenderness (60.0%) and edema (53.3%). Direct blow was the most common inciting trauma (46.2%), followed by axial load (30.8%) and avulsion injuries (23.1%). Baseline radiographs were occult in 72.7% of patients; magnetic resonance imaging and computed tomography were the most common diagnostic modalities. Mean ± SD diagnostic delay was 64.7 ± 89.6 days. Conservative management was pursued in 54.5% of patients, with reported resolution of symptoms in 3 to 6 months. Surgical intervention occurred in 45.5% of patients and resulted in functional restoration in 3 to 6 months in all but one patient.

CONCLUSIONS

Initial radiographs for isolated medial cuneiform fractures are frequently occult. Due to expedience and relatively low cost, radiographs are still a viable first-line imaging modality. If clinical concern remains, magnetic resonance imaging may be pursued to minimize diagnostic delay. Conservative management is a viable treatment method, with expected return to full function in 3 to 6 months.

Ankle Stability and Movement Coordination Impairments: Lateral Ankle Ligament Sprains Revision 2021

This revised clinical practice guideline (CPG) addresses the distinct but related lower extremity impairments of those with a first-time lateral ankle sprain (LAS) and those with chronic ankle instability (CAI). Depending on many factors, impairments may continue following injury. While most individuals experience resolution of symptoms, complaints of instability may continue and are defined as CAI. The aims of the revision were to provide a concise summary of the contemporary evidence since publication of the original guideline and to develop new recommendations or revise previously published recommendations to support evidence-based practice.

ACR Appropriateness Criteria® Acute Trauma to the Ankle

Acute injuries to the ankle are frequently encountered in the setting of the emergency room, sport, and general practice. This ACR Appropriateness Criteria defines best practices for imaging evaluation for several variants of patients presenting with acute ankle trauma. The variants include scenarios when Ottawa Rules can be evaluated, when there are exclusionary criteria, when Ottawa Rules cannot be evaluated, as well as specific injuries. Clinical scenarios are followed by the imaging choices and their appropriateness with an accompanying narrative explanation to help physicians to order the most appropriate imaging test. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Point-of-care bedside ultrasound examination for the exclusion of clinically significant ankle and fifth metatarsal bone fractures; a single blinded prospective diagnostic cohort study

OBJECTIVE

The aim of this study was to assess the diagnostic value of point-of-care bedside ultrasound (PoCUS) as in usual clinical practice in suspected ankle and fifth metatarsal bone fractures, compared to the standard of radiographic imaging.

METHODS

This prospective study included patients ≥17 years presenting to the Emergency Department with ankle trauma and positive Ottawa Ankle Rules. All patients underwent PoCUS of the ankle by a (resident) emergency physician, the images were assessed by an ultrasound expert. Both were blinded for the medical history and clinical findings of the patients. Radiography of the ankle followed, evaluated by a radiologist blinded from the PoCUS findings. Primary outcome measures were sensitivity and specificity of PoCUS.

RESULTS

A total of 242 patients were included, with 35 (22%) clinically significant (non-avulsion) fractures observed with radiography. The sensitivity of PoCUS in detecting clinically significant fractures by all sonographers was 80.0% (95% Confidence Interval (CI) 63.0 to 91.6%), specificity 90.3% (95% CI 83.7 to 94.9%), positive predictive value 70.0% (95% CI 57.0 to 80.3%) and the negative predictive value 94.1% (95% CI 89.1 to 96.9%). The sensitivity of PoCUS in detecting clinically significant fractures by the expert was 82.8% (95% CI 66.3 to 93.4%), specificity 99.2% (95% CI 95.5 to 99.9%), positive predictive value 96.7% (95% CI 80.3 to 99.5%) and the negative predictive value 95.3% (95% CI 91.0 to 98.2%).

CONCLUSION

PoCUS combined with the OAR has a good diagnostic value in usual clinical practice in the assessment of suspected ankle and fifth metatarsal bone fractures compared to radiographic imaging. More experience with PoCUS will improve the diagnostic value.

A qualitative study of health professions curricula and management of lateral ankle ligament sprain demonstrates inconsistency

BACKGROUND

Health educators aim to graduate students who are safe, effective and practice evidence-based medicine (EBM). Clinical Practice Guidelines (CPGs) are tools for translating evidence into clinical practice for health professionals and educators who lack time to appraise the evidence. There have been CPGs published for lateral ankle ligament sprains (LALS) for physiotherapists, nurses, and doctors. Clinical decision rules have also been developed for LALS to increase the safety of practice. The Ottawa Ankle Rules (OAR) were developed to screen for the need for an x-ray following an ankle or foot injury.

METHODS

Educators from the Australasian College of Sports and Exercise Physicians (ACSEP), St John Ambulance first aiders, pharmacy, nursing, and physiotherapy disciplines were participants in this study. Using purposeful sampling with semi-structured questions and a LALS case study, 19 Australian educators were interviewed. Curricula and textbooks were also collected and analysed. Two researchers independently analysed the data using a deductive method.

RESULTS

Analysis found that no educator used a CPG to inform their teaching. There was no common LALS curriculum for the five groups studied. There were two approaches: a triage curriculum (St John Ambulance, pharmacy, nursing) and a reflective curriculum (ASCEP and physiotherapy). Textbooks influenced curriculum for physiotherapy, pharmacy and first aid educators. The triage curricula recommend rest, ice, compression and elevation (RICE) alone, while the reflective curricula uses OAR, RICE, immobilisation if the LALS is severe, functional support (brace), exercises and manual therapy. In addition, ACSEP and physiotherapy do not recommend electrotherapy. All five groups were cautious about the use of non-steroidal anti-inflammatory drugs (NSAIDs).

CONCLUSIONS

Physiotherapy and ACSEP educators teach OAR. Despite not using the CPGs to inform curriculum, physiotherapy and ACSEP have unintentionally aligned their curriculum with current LALS CPG recommendations. However, nursing, pharmacy and first aid trainers are not teaching OAR or aligned with LALS CPGs. Educators in pharmacy, nursing and first aid should re-examine their curricula and consider possibly teaching OAR and using CPG. Clinical practice guideline developers should consider pharmacists and first aiders as users of their LALS CPGs.

Ultrasonography in assessing suspected bone fractures: a cross-sectional survey amongst German general practitioners

Background

Over the last two decades, ultrasonography (US) has been shown to be an accurate tool for the diagnosis of suspected bone fractures; however, the integration of this application of US into routine care and outpatient settings needs to be explored. In this study, we surveyed German general practitioners (GPs) to assess their knowledge, attitudes, and utilization of US for the diagnosis of suspected fractures.

Methods

Notification of the study, a self-designed questionnaire, and a reminder were mailed to 600 randomly selected GPs in Saxony and Saxony-Anhalt.

Results

The response rate was 47.7% (n = 286), and respondents did not differ from the population of all GPs in respect to sex and practice type. Among GPs surveyed, 48.6% used an US device in their practice. On average, GPs diagnosed six patients with suspected fractures per month, yet only 39.3% knew about the possibility of ultrasonographic fracture diagnosis, and only 4.3% of GPs using US applied it for this purpose. Among participants, 71.9% believed that US is inferior to conventional X-rays for the diagnosis of bony injuries. Users of US were better informed of and more commonly used US for fracture diagnosis compared to non-users.

Conclusion

The need to rule out possible fractures frequently arises in general practice, and US devices are broadly available. Further efforts are needed to improve the knowledge and attitudes of GPs regarding the accuracy of US for fracture diagnosis. Multicenter controlled trials could explore the safety, usefulness, and effectiveness of this still seldom used diagnostic approach for suspected fractures.

Epidemiology of injuries due to ankle sprain diagnosed in an orthopedic emergency room

Objective

To use magnetic resonance imaging to assess the prevalence of foot and ankle ligament injuries and fractures associated with ankle sprain and not diagnosed by x-ray.

Methods

We included 180 consecutive patients with a history of ankle sprain, assessed at a primary care service in a 12-month period. Magnetic resonance imaging findings were recorded and described.

Results

Approximately 92% of patients had some type of injury shown on the magnetic resonance imaging. We found 379 ligament injuries, 9 osteochondral injuries, 19 tendinous injuries and 51 fractures. Only 14 magnetic resonance imaging tests (7.8%) did not show any sort of injury. We observed a positive relation between injuries of the lateral complex, syndesmosis and medial ligaments. However, there was a negative correlation between ankle ligament injuries and midfoot injuries.

Conclusion

There was a high rate of injuries secondary to ankle sprains. We found correlation between lateral ligament injuries and syndesmosis and deltoid injuries. We did not observe a relation between deltoid and syndesmosis injuries or between lateral ligamentous and subtalar injuries. Similarly, no relation was found between ankle and midfoot injuries.

MANAGEMENT OF ACUTE GRADE II LATERAL ANKLE SPRAINS WITH AN EMPHASIS ON LIGAMENT PROTECTION: A DESCRIPTIVE CASE SERIES

Background and Purpose

Lateral ankle sprain the most common injury in physically active populations. Individuals who sustain an acute lateral ankle sprain may not receive timely formal rehabilitation and are at an increased risk to have subsequent sprains which can lead to chronic pain and instability. Attention to essential factors for ligament protection and healing while preserving ankle movement, may result in a more stable yet mobile ankle offering improved outcomes. The purpose of this case series was to describe the methods and observe the outcomes associated with a comprehensive strategy for managing acute first episode grade II lateral ankle sprains.

Study design

Prospective case series.

Case Descriptions and Interventions

Ten patients (mean age 26.7 years, range 16-51 years, mean 2.3 days from injury) with acute grade II lateral ankle sprain were treated with an approach to protect the injured ligament, prevent impairments to movement, restore strength and proprioception, and progress to full function. Patient outcomes were assessed at four, eight and 12 weeks. Follow-up interviews at six and 12 months assessed injury recurrence.

Outcomes

Patients were treated for an average of eight sessions over a mean of seven weeks. Rapid change in self-reported function, ankle ROM, and pain were observed in the first four weeks of care. Clinically meaningful improvements in function and ankle ROM were also noted at eight weeks and maintained at 12-week follow-ups. All patients returned to desired physical activity with only a single re-sprain event within one year after injury.

Conclusion

The results of this prospective case series suggest that a treatment approach designed to protect the injured ligament, maintain and restore normal ankle motion, and provide a tailored functional pathway to return to run and sport demonstrated resolution of symptoms and improvement in reported functional outcomes in a group of patients following grade II acute primary ankle sprain.

Experience using the «Shetty test» for initial foot and ankle fracture screening in the Emergency Department

OBJECTIVE

The indiscriminate practice of radiographs for foot and ankle injuries is not justified and numerous studies have corroborated the usefulness of clinical screening tests such as the Ottawa Ankle Rules. The aim of our study is to clinically validate the so-called Shetty Test in our area.

MATERIAL AND METHOD

A cross-sectional observational study by applying the Shetty test to patients seen in the Emergency Department.

RESULTS

We enrolled 100 patients with an average age of 39.25 (16-86). The Shetty test was positive on 14 occasions. Subsequent radiography revealed a fracture in 10 cases: 4 were false positives. The test was negative in the remaining 86 patients and radiography confirmed the absence of fracture (with sensitivity of 100% and specificity of 95.56%, positive predictive value of 71.40%, and negative predictive value of 100%).

CONCLUSIONS

The Shetty test is a valid clinical screening tool to decide whether simple radiography is indicated for foot and ankle injuries. It is a simple, quick and reproducible test.

Diagnosis, treatment and prevention of ankle sprains: update of an evidence-based clinical guideline

This guideline aimed to advance current understandings regarding the diagnosis, prevention and therapeutic interventions for ankle sprains by updating the existing guideline and incorporate new research. A secondary objective was to provide an update related to the cost-effectiveness of diagnostic procedures, therapeutic interventions and prevention strategies. It was posited that subsequent interaction of clinicians with this guideline could help reduce health impairments and patient burden associated with this prevalent musculoskeletal injury. The previous guideline provided evidence that the severity of ligament damage can be assessed most reliably by delayed physical examination (4-5 days post trauma). After correct diagnosis, it can be stated that even though a short time of immobilisation may be helpful in relieving pain and swelling, the patient with an acute lateral ankle ligament rupture benefits most from use of tape or a brace in combination with an exercise programme.New in this update: Participation in certain sports is associated with a heightened risk of sustaining a lateral ankle sprain. Care should be taken with non-steroidal anti-inflammatory drugs (NSAIDs) usage after an ankle sprain. They may be used to reduce pain and swelling, but usage is not without complications and NSAIDs may suppress the natural healing process. Concerning treatment, supervised exercise-based programmes preferred over passive modalities as it stimulates the recovery of functional joint stability. Surgery should be reserved for cases that do not respond to thorough and comprehensive exercise-based treatment. For the prevention of recurrent lateral ankle sprains, ankle braces should be considered as an efficacious option.

Review article: Best practice management of common ankle and foot injuries in the emergency department (part 2 of the musculoskeletal injuries rapid review series)

Ankle and foot injuries are the most common musculoskeletal injuries presenting to Australian EDs and are associated with a large societal and economic impact. The quality of ED care provided to patients with ankle and foot fractures or soft tissue injuries is critical to ensure the best possible outcomes for the patient. This rapid review investigated best practice for the assessment and management of common ankle and foot injuries in the ED. Databases including PubMed, CINAHL, EMBASE, TRIP and the grey literature, including relevant organisational websites, were searched in 2017. Primary studies, systematic reviews and guidelines were considered for inclusion. English language articles published in the last 12 years that addressed the acute assessment, management or prognosis in the ED were included. Data extraction of included articles was conducted, followed by quality appraisal to rate the level of evidence where possible. The search revealed 1242 articles, of which 71 were included in the review (n = 22 primary articles, n = 35 systematic reviews and n = 14 guidelines). This rapid review provides clinicians managing fractures and soft tissue injuries of the ankle and foot in the ED a summary of the best available evidence to enhance the quality of care for optimal patient outcomes. Following a thorough history and physical examination, including the application of the Ottawa ankle rules, ED clinicians should not only provide a diagnosis, but rate the severity of soft tissue injuries, or stability of fractures and dislocations, which are the pivotal decision points in guiding ED treatment, specialist referral and the follow-up plan.
