Ankle fractures: High implant cost is not associated with better patient reported outcomes.

INTRODUCTION: Ankle fractures comprise 9% of all fractures and are among the most common fractures requiring operative management. Open reduction and internal fixation (ORIF) with plates and screws is the gold standard for the treatment of unstable, displaced ankle fractures. While performing ORIF, orthopaedic surgeons may choose from several fixation methods including locking versus nonlocking plating and whether to use screws or suture buttons for syndesmotic injuries. Nearly all orthopaedic surgeons treat ankle fractures but most are unfamiliar with implant costs. No study to date has correlated the cost of ankle fracture fixation with health status as perceived by patients through patient reported outcomes (PROs). The purpose of this study was to determine whether there is a relationship between increasing implant cost and PROs after a rotational ankle fracture. METHODS: All ankle fractures treated with open reduction internal fixation (ORIF) at a level I academic trauma center from January 2018 to December 2022 were identified. Inclusion criteria included all rotational ankle fractures with a minimum 6-month follow-up and completed 6-month PRO. Patients were excluded for age <18, polytrauma and open fracture. Variables assessed included demographics, fracture classifications, Foot and Ankle Ability Measure-Activities of Daily Living (FAAM-ADL) score, implant type, and implant cost. RESULTS: There was a statistically significant difference in cost between fracture types (p < 0.0001) with trimalleolar fractures being the most expensive. The mean FAAM-ADL score was lowest for trimalleolar fractures at 78.9, 95% CI [75.5, 82.3]. A diagnosis of osteoporosis/osteopenia was associated with a decrease in cost of $233.3, 95% CI [-411.8, -54.8]. There was no relationship between syndesmotic fixation and implant cost, $102.6, 95% CI [-74.9, 280.0]. There was no correlation between implant cost and FAAM-ADL score at 6 months (p = 0.48). CONCLUSIONS: The utilization of higher cost ankle fixation does not correlate with better FAAM-ADL scores. Orthopaedic surgeons may choose less expensive implants to improve the value of ankle fixation without impacting patient reported outcomes.

Stress Tests for Deltoid Ligament and Syndesmosis Injury in Patients With Ankle Fracture: A Systemic Review With Meta-Analysis.

OBJECTIVES: To determine the diagnostic accuracy of various stress tests for deltoid ligament and syndesmosis injury in patients with ankle fracture. DATA SOURCES: A systemic literature search was conducted in the MEDLINE, Embase, and Cochrane Library databases to identify studies published from January 1990 to August 2022. STUDY SELECTION: Studies that evaluated external rotation or gravity stress tests or hook or tap tests for the diagnosis of deltoid ligament or syndesmosis injury were included. DATA EXTRACTION: Authors, publication years, study design, index tests, reference standards, demographic features of participants, reliability, and the numbers of true-positive, true-negative, false-positive, and false-negative subjects were extracted from 14 included studies. Article quality was assessed through the revised Quality Assessment of Diagnostic Accuracy Studies tool. DATA SYNTHESIS: The pooled sensitivity and specificity of each index test for each structure were calculated with a random-effects model using the extracted data of true-positive, true-negative, false-positive, and false-negative outcomes in all relevant studies. The overall diagnostic performance of the different index tests for different structures was determined with the estimation of the area under the curve using the summary receiver operating characteristics curve. CONCLUSIONS: The gravity stress test and the tap test exhibited high sensitivity and specificity in diagnosing deltoid ligament injury. The hook test has relatively high accuracy in diagnosing syndesmosis injury. Further studies with large sample sizes are warranted to confirm the results of this review. LEVEL OF EVIDENCE: Diagnostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Disparities in concussion diagnoses compared to ankle injuries.

BACKGROUND: Health disparities related to concussions have been reported in the literature for certain minority populations. Given the significant impact of concussions on long- and short-term function, the mitigation of barriers to accessing care is an important public health objective. OBJECTIVE: To determine if racial and ethnic disparities exist in patients who seek care for concussions compared to a control group with orthopedic ankle injuries (sprains and fractures) to minimize confounding factors that predispose to injury. DESIGN: Cohort study. SETTING: Single institution between February 2016 and December 2020. PATIENTS: A retrospective review of electronic medical records was completed for patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for concussion, ankle sprain, and ankle fracture. A total of 10,312 patients were identified: 1568 (15.2%) with concussion, 4871 (47.3%) with ankle sprain, and 3863 (37.5%) with ankle fracture. INTERVENTIONS: Patients were stratified by demographic factors, including sex, ethnicity, race, and insurance type. MAIN OUTCOME MEASURES: Diagnosis of concussion. RESULTS: The concussion group was the youngest (28.3 years ± 18.0) and had the fewest females (53.1%) compared to the ankle sprain (35.1 years ± 19.7; 58.7%) and fracture groups (44.1 years ± 21.3; 57.3%). The concussion group had a smaller proportion of Hispanic patients than the ankle sprain group (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.55-0.92, p = .010) and fracture group (OR 0.58, 95% CI 0.44-0.75, p = <.001). In addition, the concussion group was less likely to be Asian (OR 0.70, CI 0.52-0.95, p = .023) than the sprain group and less likely to be Black/African American than both sprain (OR 0.65, 95% CI 0.46-0.93, p = .017) and fracture groups (OR 0.62, 95% CI 0.43-0.89, p = .010). There were no differences across racial groups between ankle sprains and fractures. Patients with Medicaid/Medicare and self-pay had a higher likelihood of being in the concussion group than those with private insurance. CONCLUSION: Differences in concussion diagnosis may exist between certain demographic groups compared to those with ankle injuries. Efforts to mitigate disparities in concussion care are worthwhile with a focus on patient and caregiver education.

Locked intramedullary nailing provides superior functional outcomes and lower complication rates than plate fixation of distal fibula fractures. A systematic review and meta-analysis of comparative studies.

PURPOSE: This study aims to provide an updated systematic review and meta-analysis of comparative studies on the outcomes and complications of locked IMNs in comparison to ORIF using plates and screws, while avoiding limitations of similar published reviews. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, two independent team members electronically searched MEDLINE (PubMed), EMBASE, Google Scholar, SCOPUS, and Cochrane databases throughout May 2021 using the following keywords with their synonyms: "Ankle fracture fixation" AND "Open reduction and internal fixation", "locked intramedullary nail", or "complications". The primary outcomes were (1) functional outcomes, (2) complications, and (3) reoperation, while the secondary outcomes were: (1) union rate, and (2) cost. INCLUSION CRITERIA: comparative studies on outcomes and complications of plate open reduction and internal fixation (ORIF) vs. locked intramedullary nailing (IMN) of ankle fractures reporting at least one of the following parameters: functional outcomes, complications (infection, dehiscence, reoperation etc.), union, and cost. Studies reporting on non-locked intramedullary fibular nails were also excluded. RESULTS: After the removal of duplicates, a total of 1461 studies were identified. After screening those records, 63 studies remained for full-text assessment. Out of those, four comparative studies with a total of 262 ankle fractures met the inclusion criteria for this meta-analysis. The mean 12 months postoperative Olerud and Molander Ankle Scores (OMAS) were reported by two studies, with a statistically significant difference in favor of IMNs (MD= 6.72, CI: 3.77-9.67, p<0.001, I2= 94%). In the ORIF group, the overall complication rate was 39/134 (29.1%) vs. 10/128 (7.8%) in the IMN group, with a statistically significant difference in favor of the IMN group (RR=3.23, CI:1.71-6.11, p<0.001, I2=34%). In the ORIF group, the overall infection rate was 11/134 (8.2%), while there were no infections in the IMN group, with a statistically significant difference in favor of the IMN group (RR=8.05, CI:1.51-42.82, p=0.01, I2=0%). In the ORIF group, the overall reoperation rate was 10/134 (7.5%) while the overall reoperation rate was 6/128 (4.7%) in the IMN group, with no statistically significant difference between groups (RR=1.49, CI: 0.60-3.70, p = 0.39, I2=0%). CONCLUSION: Locked intramedullary nail fixation of distal fibula fractures could provide superior functional outcomes and lower complication rates in comparison to open reduction and plate fixation. Despite the high incidence of ankle fractures, the number of high-quality comparative studies remains limited in literature, especially on newer locked fibular nails, and large multicentric clinical trials are required before recommending locked IMNs as the new standard of care in distal fibula fractures.

The Syndesmosis, Part I: Anatomy, Injury Mechanism, Classification, and Diagnosis.

Ankle fractures are common injuries to the lower extremity with approximately 20% sustaining a concomitant injury to the syndesmosis. Although the deltoid ligament is not formally included in the syndesmotic complex, it plays an important role in the mortise stability. Therefore, its integrity should be always evaluated when syndesmotic injury is suspected. Given the anatomic variability of the syndesmosis between individuals, bilateral ankle imaging is recommended, especially in cases of subtle instability. Diagnostic tests that allow dynamic assessment of the distal tibiofibular joint in the 3 planes are the most reliable in determining the presence of syndesmotic injury.

The Syndesmosis, Part II: Surgical Treatment Strategies.

Syndesmotic injuries in the setting of ankle fracture are critically important to diagnosis and treat to restore an anatomic tibiotalar relationship. Physical examination and clinical suspicion remain critically important for diagnosis. Ultrasound examination and weight-bearing computed tomography scans are evolving to help diagnosis more subtle injuries. Although flexible syndesmotic fixation may decrease malreduction rates, the benefits over rigid fixation is the subject of ongoing study. Anatomic reduction remains critical regardless of fixation choice. Routine removal of rigid syndesmotic hardware does not seem to offer substantial clinical improvement in pain or range of motion; however, broken hardware may cause irritation.

Tertiary survey by trauma nurse specialist at a paediatric trauma centre.

INTRODUCTION: Tertiary surveys aim to detect injuries missed in the initial assessment of trauma. We introduced a process by which the trauma nurse specialist performed a number of the tertiary surveys (NTSs) at our paediatric trauma centre. METHODS: Data from the first six months following introduction of the NTS were compared to retrospective data from the six months prior to NTS implementation (pre-NTS), when trauma surveys were completed by medical staff. RESULTS: Over the 12-month period, 130 children met the criteria for a tertiary survey. Pre-NTS, 57/62 eligible patients received a tertiary survey, compared to 61/68 during NTS (p=0.77). There were significantly more road traffic crash patients in the NTS group (p=0.008) but no significant differences by demographics, injury pattern, injury severity score or outcomes. New injuries were found in three patients pre-NTS compared to five patients during NTS (odds ratio 1.3 (95%CI 1.3-2.0, p=0.73)). CONCLUSION: This study conservatively supports the hypothesis that, with training and support, a trauma nurse specialist can perform tertiary surveys as effectively as doctors. A larger study is required to confirm these findings.

Use of cast immobilisation versus removable brace in adults with an ankle fracture: multicentre randomised controlled trial.

OBJECTIVES: To assess function, quality of life, resource use, and complications in adults treated with plaster cast immobilisation versus a removable brace for ankle fracture. DESIGN: Multicentre randomised controlled trial. SETTING: 20 trauma units in the UK National Health Service. PARTICIPANTS: 669 adults aged 18 years and older with an acute ankle fracture suitable for cast immobilisation: 334 were randomised to a plaster cast and 335 to a removable brace. INTERVENTIONS: A below the knee cast was applied and ankle range of movement exercises started on cast removal. The removable brace was fitted, and ankle range of movement exercises were started immediately. MAIN OUTCOME MEASURES: Primary outcome was the Olerud Molander ankle score at 16 weeks, analysed by intention to treat. Secondary outcomes were Manchester-Oxford foot questionnaire, disability rating index, quality of life, and complications at 6, 10, and 16 weeks. RESULTS: The mean age of participants was 46 years (SD 17 years) and 381 (57%) were women. 502 (75%) participants completed the study. No statistically significant difference was found in the Olerud Molander ankle score between the cast and removable brace groups at 16 weeks (favours brace: 1.8, 95% confidence interval -2.0 to 5.6). No clinically significant differences were found in the Olerud Molander ankle scores at other time points, in the secondary unadjusted, imputed, or per protocol analyses. CONCLUSIONS: Traditional plaster casting was not found to be superior to functional bracing in adults with an ankle fracture. No statistically difference was found in the Olerud Molander ankle score between the trial arms at 16 weeks. TRIAL REGISTRATION: ISRCTN registry ISRCTN15537280.

Does the Covid-19 pandemic affect ankle fracture incidence? Moderate decrease in Sweden.

Background and purpose - While many other countries implemented strict regulations and restrictions for their citizens during the 1st wave of the Covid-19 pandemic, Sweden maintained a more restrained approach. The Swedish Public Health Agency emphasized individual responsibility and pushed for behavioral changes. With strict lockdown a 77% decrease in ankle fracture incidence has been reported. We investigated whether there was a change in the incidence of ankle fractures seen at 7 selected hospitals during the Covid-19 pandemic 2020.Patients and methods - Data on all ankle fractures treated at 7 selected departments during March 15 through June 15, 2020, and for the same period in the preceding 3 years (2017-2019), was retrieved from the Swedish Fracture Register. The number of fractures during the whole period and subsequent 30-day periods were compared between 2020 and 2017-2019, including subgroup analyses of age and sex.Results - The monthly rate of ankle fractures was reduced by 14% in 2020 (139 fractures) compared with 2017-2019 (161 fractures). Women had a 16% decrease and patients aged > 70 years had a 29% decrease. During the 1st 30-day period, a 26% decrease in fractures was seen.Interpretation - During the 1st wave of the Covid-19 pandemic, a moderate decline in the number of ankle fractures was seen. Women and patients aged > 70 years displayed the greatest reduction. The greatest reduction in incidence of fractures was seen during the 1st 30-day period. This indicates greater adherence to government recommendations regarding social distancing in these subgroups and during the 1st month of the pandemic. Changes in ankle fracture incidence may be a measure of lockdown extent.

Peripheral nerve block anaesthesia and postoperative pain in acute ankle fracture surgery: the AnAnkle randomised trial.

BACKGROUND: Peripheral nerve blocks (PNBs) are increasingly popular in acute ankle fracture surgery but rebound pain may outweigh the benefits. The AnAnkle Trial was designed to assess the postoperative pain profile of PNB anaesthesia compared with spinal anaesthesia (SA). METHODS: The AnAnkle Trial was a randomised, two-centre, blinded outcome analysis trial. Eligible adults booked for primary ankle fracture surgery were randomised to PNB or SA. The PNBs were ultrasound-guided popliteal sciatic and saphenous blocks with ropivacaine and SAs were with hyperbaric bupivacaine. Postoperatively, all subjects received paracetamol, ibuprofen, and patient-controlled i.v. morphine for pain. The primary endpoint was 27 h Pain Intensity and Opioid Consumption (PIOC) score. Secondary endpoints included longitudinal pain scores and morphine consumption separately, and questionnaires on quality of recovery. RESULTS: This study enrolled 150 subjects, and the PNB success rate was >94%. PIOC was lower with PNB anaesthesia (median, -26.5% vs +54.3%; P<0.001) and the probability of a better PIOC score with PNB than with SA was 74.8% (95% confidence interval, 67.0-82.6). Pain scores and morphine consumption analysed separately also yielded a clear benefit with PNB, despite substantial rebound pain when PNBs subsided. Quality of recovery scores were similar between groups, but 99% having PNB vs 90% having SA would choose the same anaesthesia form again (P=0.03). CONCLUSIONS: PNB anaesthesia was efficient and provided a superior postoperative pain profile compared with SA for acute ankle fracture surgery, despite potentially intense rebound pain after PNB.

[Unstable injuries of the deltoid ligament complex in ankle fractures : How to diagnose, how to treat?] / Instabile Verletzungen des Deltabandkomplexes bei Sprunggelenkfrakturen : Wie erkennen, wie behandeln?

Unstable injuries of the deltoid ligament complex can have a substantial negative effect on the prognosis and treatment of ankle injuries. Lesions of the deltoid ligament are often overlooked at the initial presentation, both as isolated ruptures and in combination with more complex injuries of the ankle. Neglected unstable injuries of medial ankle ligaments may result in chronic instability, especially following correct treatment of fractures and lateral ligament injuries. These are accompanied by reduced ankle mobility, persisting pain, reduced load bearing and osteoarthritis. Despite the possible subsequent damage, the need for surgical repair of the deltoid ligament in patients with ankle fractures is controversially discussed. Although in most cases of ligament injuries of the upper ankle joint conservative treatment leads to very good results, there is increased interest in acute surgical treatment particularly for unstable injuries in order to avoid secondary instability and the associated sequelae. When surgical treatment should be given priority over conservative treatment has not yet been sufficiently clarified. This article gives an overview of the diagnosis and treatment of injuries of the deltoid ligament complex in patients with ankle fractures based on the current literature.

Value of Ultrasound for Stability Assessment of Isolated Lateral Malleolar Fractures Compared to Stress Radiography and Arthroscopy.

BACKGROUND: This study was performed to evaluate the value of using ultrasound for stability assessment of isolated lateral malleolar fractures compared to simple X-ray, stress radiography, and arthroscopy. METHODS: This is a prospective cohort study with 25 consecutive patients who underwent an arthroscopic examination and subsequent surgery for isolated lateral malleolar ankle fractures. Before operation, simple and external rotation stress radiographs were obtained. Ultrasound was performed to assess the medial deltoid ligament prior to operation. Arthroscopic findings were used as reference standards. Sensitivity, specificity, and positive and negative predictability were calculated and compared using receiver operating characteristic (ROC) curve analysis for simple radiography, stress radiography, and ultrasound examination. RESULTS: The sensitivity and specificity of ultrasound for tears of the deep deltoid ligament were 94.74% and 66.67%, respectively. But, they were both 100% for complete tears of the ligament. ROC curve analysis showed that the ultrasound examination was significantly more accurate than simple and stress radiography. CONCLUSIONS: Ultrasound could be used to assess the instability of isolated lateral malleolar fractures. Commonly used stress radiography appears to overrate the need for operative treatment.

The new ultralow dose CT protocol for the diagnosis of fractures of the ankle: A prospective comparative study with conventional CT.

PURPOSE: Computerized tomography (CT) imaging is increasingly being used to evaluate patients with ankle trauma. However, conventional CT (C CT) has a significantly higher radiation dose (RD) than plain radiography. This study aimed to evaluate the diagnostic accuracy and reliability of ultra-low-dose CT (ULDCT) protocol for ankle fractures. METHODS: Ninety-eight consecutive patients who had ankle CT for suspected ankle fracture were included in our prospective study. C CT and ULDCT protocols were simultaneously performed on these 98 patients. Two observers independently evaluated ULDCT and C CT images. The effective RD of the ULDCT and C CT groups was calculated. RESULTS: The interobserver agreement was 1 (perfect). ULDCT and C CT group images showed no significant difference in image quality. The effective RD of the ULDCT was significantly lower than the C CT (p < 0.001). CONCLUSIONS: By evaluating the results of this study, ULDCT proved to be a reliable diagnostic imaging method for fractures of the ankle. The satisfactory diagnostic image quality of the ULDCT protocol provides promising results. LEVEL OF EVIDENCE: Level II/lesser quality RCT or prospective comparative study.

Is there any change in surgeon's attitude to the management of ankle fractures accompanying syndesmotic injury? A nationwide survey.

OBJECTIVES: This study aims to investigate the attitudes of orthopedic surgeons to the management of ankle fractures accompanied by syndesmotic injury with a nationwide survey. PATIENTS AND METHODS: In the first step of this descriptive study, an electronic survey was prepared in Google drive and a survey link was sent to the Turk-Ortopedi e-mail group between 09 and 19 January 2019. The orthopedic surgeons and residents were requested to complete the questionnaire. A total of 320 orthopedic surgeons (77%) and residents (23%) participated in the survey. The responses were analyzed statistically. To evaluate the changing attitudes, our results were compared with the surgeon survey studies key worded "syndesmotic injury" in PubMed. RESULTS: The majority of the participants stated that they used the hook test, external rotation stress test, and fluoroscopy together (47.2%) for the diagnosis of syndesmotic injury during the operation. Of the participants, the majority (93%) reported to use metallic syndesmotic screws, and 59% reported to remove the syndesmotic screw routinely. Young surgeons with 5 to 10 years of experience preferred intraoperative diagnosis methods compared to surgeons with more than 20 years of experience. Foot and ankle surgeons and sports surgeons reported to allow weight bearing before removal of the screw much more than other unspecified branches. CONCLUSION: The preferences of the surgeon vary in syndesmotic injuries and there is still no consensus regarding diagnosis and rehabilitation. Compared to the past decade, fewer surgeons prefer to remove the screws today.

A combination of bimalleolar fracture and fracture on talar body and neck: A rare case report.

RATIONALE: Talar fracture accompanied with malleolar fracture is rare, and its management is complex. Ankle soft tissue is much thinner than other parts of the human body, and the shape of the ankle makes wounds difficult to close immediately after surgery, which may result in poor skin condition if the wound tension is too high. However, joint congruity and osteonecrosis are the main concerns of talar fracture. PATIENT CONCERNS: A 57-year-old man presented at the emergency department following a motorcycle accident. DIAGNOSES: Physical examination revealed swelling and tenderness of the left ankle and midfoot. The patient had comminuted talar fracture and was indicated for dual-screw fixation or even plate with screw fixation. INTERVENTIONS: We performed single screw fixation after assessing the soft tissue condition and employed a technique of using continuous longitudinal force to bring together fracture fragments (ankle ligamentotaxis) during surgery. Open reduction with a mini-hook plate and tension band wire was used for bimalleolar fracture repair using the combined anteromedial and anterolateral approach with extension of the incision. Kirschner wire for temporary fixation was performed using ligamentotaxis, and a 2.4 headless screw was inserted from the posteromedial to the anterolateral direction. OUTCOMES: The patient was discharged with a standard short leg splint and was instructed not to bear weight on the affected ankle for 2 months. The patient walked well without discomfort, and the Hawkins sign was clearly visible. Single screw fixation preserves the integrity of the talus bone as minimal space is used for this operative technique. Single screw fixation preserves more bony stock when most of the internal fixator is located within the bone. Additionally, surgery time is shorter than multiple implantations even when performing the same procedure; as a result, there was less ankle soft tissue swelling. LESSONS: This case provides evidence of using the single screw fixation technique for addressing both malleolar and talar fractures, and that talar fracture management can be less aggressive with limited weight bearing and initial limited range of motion given the presence of malleolar fracture. The alignment and stability of bony fragments also benefit from ankle ligamentotaxis.

Ankle Fracture Epidemiology in the United States: Patient-Related Trends and Mechanisms of Injury.

Current nationwide epidemiological data regarding ankle fractures are scarce. Such information is important towards better quantifying the mortality associated with such injuries, financial impact, as well as the implementation of preventative measures. This study evaluated the epidemiology of ankle fractures that occurred during a 5-year period. Specifically, we evaluated demographics, mechanism of injury, and disposition. The National Electronic Injury Surveillance System was queried to identify all patients with ankle fractures that presented to US hospital emergency departments between 2012 and 2016. Census data were used to determine the incidence rates of ankle fractures in terms of age, sex, and race. There was an estimated total of 673,214 ankle fractures that occurred during this period, with an incidence rate of 4.22/10,000 person-years. The mean age of patients with an ankle fracture was 37 ± 22.86 (SD) years; 23.5% of ankle fractures occurred in patients aged 10 to 19 years (7.56/10,000 person-years). In addition, 44% of ankle fractures occurred in men (3.81/10,000 person-years), whereas 56% occurred in women (4.63/10,000 person-years). Data on race/ethnicity were available for 71% of the subjects, with incidence rates of 2.85/10,000 person-years for whites, 3.01/10,000 person-years for blacks, and 4.08/10,000 person-years for others. The most common mechanism of injury was falls (54.83%), followed by sports (20.76%), exercise (16.84%), jumping (4.42%), trauma (2.84%), and other (0.30%). For disposition, 81.84% of patients were treated and released, 1.43% were transferred, 16.01% were admitted, 0.59% were held for observation, and 0.13% left against medical advice. The highest incidence of ankle fractures in men occurred in the 10-to-19-years age group, but women were more commonly affected in all other age groups.

Revision of the Chronic Syndesmotic Injury.

Optimal healing for fractures requires anatomic reduction and stable fixation. This optimizes not only bone healing, but optimal function within the limb including joint functioning. Proper ligamentous healing is also crucial for optimal functioning. In patients with injuries around the ankle involving distal tibiofibular syndesmotic injuries of the ankle, malreduction of the syndesmosis is a potential consequence that can lead to chronic pain and functional limitations. This article discusses proper ways of evaluating reduction of the syndesmosis and surgical revision for the chronic injury.

Utility of Ottawa Ankle Rules in an Aging Population: Evidence for Addition of an Age Criterion.

The Ottawa ankle rules (OAR) indicate that any patient with the inability to ambulate up to four steps or with tenderness at either malleoli should receive diagnostic imaging for an acute ankle injury. Current trends indicate that health care providers tend to order more images in practice than necessary according to OAR. The purpose of this study is to analyze OAR in geriatric versus nongeriatric patients. Secondarily, we hope to refine these guidelines for ankle imaging in the hopes that health care providers will be comfortable in adhering to these guidelines more strictly. A retrospective chart review was conducted of 491 adult patients with an average (± standard deviation) age of 54.4 ± 21.6 years (range 18 to 96). Applying the current OAR resulted in a sensitivity of 98.2% and a specificity of 58.6% in this entire cohort. The calculated sensitivities were comparable between the nongeriatric and geriatric cohorts, at 98.60% and 97.99%, respectively. The specificities varied between the nongeriatric and geriatric cohorts, at 60.13% and 33.33%. We propose new guidelines that would mandate imaging studies for any patient ≥65 years of age presenting to the emergency department with ankle pain. When applying these proposed guidelines, the sensitivity of the entire study population was found to be improved to 99.0%, whereas the specificity dropped to 56.7%. The slight decrease in specificity was deemed acceptable because these guidelines are meant to be used as a screening tool and because the risk of OAR not correctly identifying ankle fracture (2% of geriatric fractures) was completely mitigated in the geriatric population.
