Effectiveness of prophylactic ankle stabilisers for prevention of ankle injuries.

Ankle injuries are common at many levels of athletic participation. A relatively recent approach in injury intervention is the use of prophylactic ankle stabilisers (PAS). PAS are used with the intention of reducing the frequency and severity of ankle injuries in a cost-effective manner. To date, 4 studies have been completed to determine the clinical efficacy of PAS. Although all of the studies have methodological limitations, a general consensus of agreement exists among the findings: PAS are effective in reducing the incidence of acute ankle sprains. However, the effect of PAS on ankle sprain severity remains unclear, as varying results have been reported. PAS do not increase the risk of knee injuries. The use of PAS for ankle injury reduction appears to be justified although further research is required.

Ankle injuries and ankle strength, flexibility, and proprioception in college basketball players.

OBJECTIVE: To determine if ankle muscular strength, flexibility and proprioception can predict ankle injury in college basketball players and to compare ankle injury rates in female and male players. DESIGN AND SETTING: In this prospective, correlational study, subjects were tested at the start of the competitive season for ankle joint muscle strength, flexibility, and proprioception. The first ankle injury for each subject was recorded on an injury report form, and the data were analyzed to determine if any of these preseason measurements predicted future injury. The setting was a competitive 9-week season for four women's and four men's college basketball teams. SUBJECTS: A convenience sample of 31 female and 11 male college basketball players. MEASUREMENTS: Subjects were tested for ankle dorsiflexion range of motion, various measures of ankle proprioception, and isokinetic peak torque of ankle dorsiflexion-plantar flexion and eversion-inversion at 30 degrees /sec and 180 degrees /sec before the start of the conference basketball seasons. Data were analyzed using a series of multiple regression equations to determine the variance in ankle injury attributed to each variable. RESULTS: Various measures of proprioception predicted left ankle injury in all subjects (p < .05), while ankle strength and flexibility measures failed to account for additional variance. There was no statistically significant difference in ankle injury rate between women and men. CONCLUSIONS: Ankle joint proprioceptive deficits can be used to predict ankle injury, but further research is needed to identify other sources of variance. In our study, ankle injury rate was similar in female and male college basketball players.

Early local experience of ankle arthrography and its influence on management of patients with ankle injury.

Ankle arthrography was performed on 64 patients with a history of ankle injury from 21 January 1986 to 11 October 1988. There was a male predominance in the ratio of 15 to 1 and the mean age of our patients was 22 years. A total of 65 arthrograms were obtained as one patient had bilateral ankle arthrograms. Of these, 29 arthrograms were normal. A year after completing this study, we attempted to retrieve our patients' case-notes and reviewed their subsequent management. Our results showed that multiple factors influenced the further management of our patients and arthrogram did play a role in this respect.

Comparison of current local practice and the Ottawa Ankle Rules to determine the need for radiography in acute ankle injury.

Ankle injuries are a frequent cause of attendance to accident and emergency (A&E) departments. Although often classed as 'minor injuries', the consequences of mismanagement can be debilitating for patients. In addition, it is not always easy to differentiate those injuries with bony fractures from solely ligamentous injuries, and most patients are radiographed unnecessarily. Clinical prediction rules such as the Ottawa Ankle Rules have been devised to reduce the degree of radiographic requests, thus limiting harmful radiation exposure, and reducing departmental costs. The A&E environment of our centre often includes a variety of clinicians with little pure orthopaedic training or knowledge of these clinical prediction rules, hence, providing a prime atmosphere for their assessing their effectiveness. A prospective study was performed in our centre to investigate the validity of the clinician's decision in diagnosis of a bony injury in the absence of training with the Ottawa Ankle Rules. The effectiveness of applying the rules was then determined on the same set of patients.

A systematic review on ankle injury and ankle sprain in sports.

This article systematically reviews epidemiological studies on sports injury from 1977 to 2005 in which ankle injury was included. A total of 227 studies reporting injury pattern in 70 sports from 38 countries were included. A total of 201,600 patients were included, with 32,509 ankle injuries. Ankle injury information was available from 14,098 patients, with 11 847 ankle sprains. Results show that the ankle was the most common injured body site in 24 of 70 included sports, especially in aeroball, wall climbing, indoor volleyball, mountaineering, netball and field events in track and field. Ankle sprain was the major ankle injury in 33 of 43 sports, especially in Australian football, field hockey, handball, orienteering, scooter and squash. In sports injuries throughout the countries studied, the ankle was the second most common injured body site after the knee, and ankle sprain was the most common type of ankle injury. The incidence of ankle injury and ankle sprain was high in court games and team sports, such as rugby, soccer, volleyball, handball and basketball. This systematic review provides a summary of the epidemiology of ankle injury in sports.

Multicentre trial to introduce the Ottawa ankle rules for use of radiography in acute ankle injuries. Multicentre Ankle Rule Study Group.

OBJECTIVE: To assess the feasibility and impact of introducing the Ottawa ankle rules to a large number of physicians in a wide variety of hospital and community settings over a prolonged period of time. DESIGN: Multicentre before and after controlled clinical trial. SETTING: Emergency departments of eight teaching and community hospitals in Canadian communities (population 10,000 to 3,000,000). SUBJECTS: All 12,777 adults (6288 control, 6489 intervention) seen with acute ankle injuries during two 12 month periods before and after the intervention. INTERVENTION: More than 200 physicians of varying experience were taught to order radiography according to the Ottawa ankle rules. MAIN OUTCOME MEASURES: Referral for ankle and foot radiography. RESULTS: There were significant reductions in use of ankle radiography at all eight hospitals and within a priori subgroups: for all hospitals combined 82.8% control v 60.9% intervention(P < 0.001); for community hospitals 86.7% v 61.7%; (P < 0.001); for teaching hospitals 77.9% v 59.9%; (P < 0.001); for emergency physicians 82.1% v 61.6%; (P < 0.001); for family physicians 84.3% v 60.1%; (P < 0.001); and for housestaff 82.3% v 60.1%; (P < 0.001). Compared with patients without fracture who had radiography during the intervention period those who had no radiography spent less time in the emergency department (54.0 v 86.9 minutes; P < 0.001) and had lower medical charges ($70.20 v $161.60; P < 0.001). There was no difference in the rate of fractures diagnosed after discharge from the emergency department (0.5 v 0.4%). CONCLUSIONS: Introduction of the Ottawa ankle rules proved to be feasible in a large variety of hospital and community settings. Use of the rules over a prolonged period of time by many physicians of varying experience led to a decrease in ankle radiography, waiting times, and costs without an increased rate of missed fractures. The multiphase methodological approach used to develop and implement these rules may be applied to other clinical problems.

Comparison of diagnostic decision rules and structured data collection in assessment of acute ankle injury.

BACKGROUND: Ankle decision rules help to determine which patients with ankle injuries should undergo radiography. However, these rules are limited by imperfect generalizability and sensitivity. The judgement of physicians, aided by structured data collection, is a potential alternative. We compared the diagnostic performance of 2 decision rules with the performance of physicians, aided by structured data collection, in ruling out fracture in patients with acute ankle injury. METHODS: Consecutive patients with acute ankle injury who visited the emergency department of a teaching community hospital in Amsterdam were included in the study. After taking the patient's history and performing a physical examination, the surgical resident in each case completed a specially developed structured data form incorporating all of the variables in the Ottawa and Leiden ankle rules, as well as some additional variables. The form then asked whether the resident thought radiography was necessary. Each patient then underwent ankle and midfoot radiography. The films were independently interpreted by a radiologist and a trauma surgeon, who were both blinded to the information on the data form. Sensitivity, specificity and the percentage of patients for whom radiography was recommended were the main outcome measures. RESULTS: Of 690 consecutive patients, 647 met the inclusion criteria. Fractures were observed in 74 (11%) of these patients. Sensitivity was 89% (95% confidence interval [CI] 80% to 95%) for the Ottawa ankle rules, 80% (95% CI 69% to 88%) for the Leiden ankle rule and 82% (95% CI 72% to 90%) for physicians' judgement. Specificity was 26% (95% CI 23% to 30%), 59% (95% CI 55% to 63%) and 68% (95% CI 64% to 71%) respectively. Radiography was recommended in 76% (95% CI 72% to 79%), 46% (95% CI 42% to 50%) and 38% (95% CI 34% to 42%) of cases respectively. The Ottawa rules missed 8 fractures, of which 1 was clinically significant, the Leiden rule missed 15 fractures, of which 5 were clinically significant, and the residents missed 13 fractures, of which 1 was clinically significant. INTERPRETATION: Physicians' judgement, aided by structured data collection, was similar to existing international and local decision rules in terms of sensitivity in identifying cases requiring radiography and may outperform these prediction rules in terms of minimizing radiographic examinations for patients with ankle trauma.

Acute ankle injury.

Acute ankle injury is a problem observed in people performing daily and work activities as well as in the athlete. The ankle is the most commonly injured joint in the body. Understanding the anatomy and mechanism of injury facilitates evaluation, diagnosis, and management. Evaluation, diagnostic imaging, and treatment options are presented. Most injuries can be managed conservatively in the primary care setting. A systematic approach to ankle evaluation can differentiate between injuries requiring orthopedic referral and those that can be managed by the nurse practitioner.

Radiologic case study. Fractures of the foot masquerading as ankle injuries.

An ankle radiographic series frequently is obtained when a patient presents with an acute ankle and foot injury. Although many fractures are confined to the ankle and are readily apparent, fractures of the foot can mimic ankle injuries. It is important to differentiate these fractures of the foot from the more common ankle sprain. Most ankle sprains are treated with ice, compression, and elevation, followed by range-of-motion exercises and progressive weight bearing as tolerated. When foot fractures are not identified, however, lack of appropriate treatment can result in late complications. Concentration on key areas as described here will reduce the incidence of missed fractures of the foot in these patients.

Radiography in acute ankle injuries: the Ottawa Ankle Rules versus local diagnostic decision rules.

STUDY OBJECTIVE: We validate the Ottawa Ankle Rules and 2 Dutch ankle rules in distinguishing clinically significant fractures from insignificant fractures and other injuries in patients with a painful ankle presenting to the emergency department. METHODS: This prospective comparison of 3 ankle rules was conducted in the ED of a 580-bed community teaching hospital in Amsterdam from January 1998 to April 1999. Participants included 647 consecutive patients aged 18 years or older presenting with a painful ankle after trauma. All physicians received extensive and pictorial training on how to correctly score the respective items of the rules. The physician on call recorded these items derived from history and physical examination on a standardized data sheet. All patients subsequently underwent standard radiographic assessment. A radiologist and a trauma surgeon evaluated the radiographs blinded from the results of the data sheet form and the treatment given. The diagnostic performance of the 3 rules was measured in terms of sensitivity, specificity, and the reduction of radiographs. Receiver operating characteristic (ROC) curves were constructed, and the area under the ROC curves was calculated and compared. RESULTS: Seventy-four fractures were seen, of which 41 were clinically significant. The Ottawa Ankle Rules had a sensitivity of 98% for identifying clinically significant fractures; the local rules scored 88% and 59%, respectively. The potential savings in radiographs for the 3 decision rules were 24%, 54%, and 82%, respectively. The area under the ROC curve was better for both the local rules (0.84 and 0.83) compared with the Ottawa Ankle Rules (0.76). CONCLUSION: Because the identification of all relevant fractures is more important than a reduction in radiographs, the higher sensitivity of the Ottawa Ankle Rules makes these most suitable for implementation in The Netherlands.

Decision rules for roentgenography of children with acute ankle injuries.

OBJECTIVE: The Ottawa Ankle Rules (OAR) assist emergency physicians in the appropriate use of roentgenography in adults with acute ankle injuries. The OAR state that ankle roentgenograms are needed only if there is pain near the malleoli and one or more of the following exists: (1) age 55 years or older; (2) inability to bear weight; or (3) bone tenderness at the posterior edge or tip of either malleolus. This study assessed the utility of the OAR on pediatric patients with acute ankle injuries. DESIGN: Prospective, consecutive survey of pediatric patients with acute ankle injuries. SETTING: Pediatric emergency department of an urban university hospital. PARTICIPANTS: Seventy-one children with acute ankle injuries were enrolled from July 22, 1993, to December 1, 1993. INTERVENTIONS: Twenty-four standardized clinical variables were assessed and recorded by physicians in the pediatric emergency department. The OAR were applied to each patient by the investigator to determine which ones would qualify for roentgenography. MAIN OUTCOME MEASURES: Sensitivity and specificity of the OAR were calculated, as was percent reduction in roentgenograms ordered. RESULTS: Seventy-one of 73 eligible patients were enrolled. The two missed patients had open fractures of the tibia. Sixty-eight of 71 patients had ankle roentgenography during the visit. Fourteen patients (21%) (mean age, 11.8 +/- 4.0 years) had fractures noted on the roentgenograms. Fifty-four patients (79%) (mean age, 12.0 +/- 3.6 years) had no fracture. Application of the OAR would have reduced the number of roentgenograms ordered by 25% without missing any fractures. Sensitivity of OAR was 100% (95% confidence interval, 77% to 100%), specificity was 32% (95% confidence interval, 21% to 43%), negative predictive value was 100% (95% confidence interval, 80% to 100%), and positive predictive value was 28% (95% confidence interval, 17% to 39%). CONCLUSIONS: Initial testing suggests that the OAR may help determine which children with acute ankle injuries could safely forgo roentgenograms without risk of missing fractures.

Radiographic classification of ankle injuries.

The initial ankle radiographs of 144 patients with ankle injuries were used to predict the total extent of ankle injury. Using the operative, clinical and radiographic findings, each injury was then classified according to the Lauge-Hansen system. Three patterns of lateral mallecolar fracture were unique to specific mechanisms of injury, with transverse fractures occurring in supination-adduction injuries, spiral fractures in supination lateral rotation injuries, and bending fractures in pronation abduction injuries. Vertical medial mallecolar fractures occurred only with supination-adduction injuries. Oblique and transverse medial malleolar fractures were not characteristic of a particular mechanism of injury. The complete extent of injury was accurately determined by the ankle radiographs in all but four patients. In these, the deltoid ligament tears could not be predicted by the radiographic findings.

Long term outcomes of inversion ankle injuries.

BACKGROUND: Ankle sprains are common sporting injuries generally believed to be benign and self limiting. However, some studies report a significant proportion of patients with ankle sprains having persistent symptoms for months or even years. AIMS: To determine the proportion of patients presenting to an Australian sports medicine clinic who had long term symptoms after a sports related inversion ankle sprain. METHODS: Consecutive patients referred to the NSW Institute of Sports Medicine from August 1999 to August 2002 with inversion ankle sprain were included. Exclusion criteria were fracture, ankle surgery, or concurrent lower limb problems. A control group, matched for age and sex, was recruited from patients attending the clinic for upper limb injuries in the same time period. Current ankle symptoms, ankle related disability, and current health status were ascertained through a structured telephone interview. RESULTS: Nineteen patients and matched controls were recruited and interviewed. The mean age in the ankle group was 20 (range 13-28). Twelve patients (63%) were male. Average follow up was 29 months. Only five (26%) ankle injured patients had recovered fully, with no pain, swelling, giving way, or weakness at follow up. None of the control group reported these symptoms (p<0.0001). Assessments of quality of life using short form-36 questionnaires (SF36) revealed a difference in the general health subscale between the two groups, favouring the control arm (p<0.05). There were no significant differences in the other SF36 subscales between the two groups. CONCLUSION: Most patients who sustained an inversion ankle injury at sport and who were subsequently referred to a sports medicine clinic had persistent symptoms for at least two years after their injury. This reinforces the importance of prevention and early effective treatment.
