Objective: To present recommendations for athletic trainers and other allied health care professionals in the conservative management and prevention of ankle sprains in athletes.Background: Because ankle sprains are a common and often disabling injury in athletes, athletic trainers and other sports health care professionals must be able to implement the most current and evidence-supported treatment strategies to ensure safe and rapid return to play. Equally important is initiating preventive measures to mitigate both first-time sprains and the chance of reinjury. Therefore, considerations for appropriate preventive measures (including taping and bracing), initial assessment, both short-and long-term management strategies, return-to-play guidelines, and recommendations for syndesmotic ankle sprains and chronic ankle instability are presented.Recommendations: The recommendations included in this position statement are intended to provide athletic trainers and other sports health care professionals with guidelines and criteria to deliver the best health care possible for the prevention and management of ankle sprains. An endorsement as to best practice is made whenever evidence supporting the recommendation is available.

Sixty consecutive collegiate athletes with "high" ankle symptoms were prospectively evaluated over a 3-year period in an effort to better define this debilitating ankle injury. All athletes included in this study had tenderness over the distal anterior tibiofibular ligament, tenderness proximally along the interosseous membrane, and functional disability. No study subject had a fracture or frank tibia-fibula diastasis. The severity of the sprain was quantified using the interosseous "tenderness length." A standard rehabilitation protocol was followed by all patients. Athletes returned to competition when they could perform all functional testing without difficulty. Time to return to full competitive activity averaged 13.4 days. The number of days missed from competition was statistically related to the interosseous tenderness length (P = 0.0001) and to positive results on the squeeze test (P = 0.03). Fifty-three of the 60 injured athletes were evaluated at least 6 months after injury. Patients rated their outcomes as good or excellent. Six of the patients experienced occasional ankle pain and stiffness, four patients reported recurrent ankle sprains, and one patient had heterotopic ossification formation.

Background:Bony stress injuries (BSIs) are common among adolescents involved in high school sports. A better understanding of factors that contribute to adolescent BSI is needed to target preventative measures.Hypothesis:Individuals who suffer a BSI will demonstrate significant differences in training methods, sleep, diet, and history of injury compared with a healthy, noninjured control group.Study Design:Descriptive epidemiologic study.Methods:Data from the National High School Stress Fracture Registry (NHSSFR), an internet-based adolescent BSI survey, were used to identify variables reported with adolescent (13-18 years of age) BSI. These findings were compared with a survey of 100 (50 males, 50 females) healthy athletic controls to identify significant differences between healthy adolescents and those with BSI.Results:A total of 346 stress fractures were reported in 314 (206 females, 108 males) athletes within the NHSSFR. Comparison with healthy control participants demonstrated multiple significant findings. In particular, body mass index was significantly lower for patients with BSI injury compared with controls ( P < 0.001). Patients slept significantly less than the control group (7.2 vs 7.95 hours; F = 34.41; P < 0.001). Females also slept significantly less hours than males (7.2 vs 7.63 hours; F = 11.02; P < 0.001). Fifty-eight percent of those who reported a BSI did not engage in any weight training. Those with a BSI had significantly higher average stress ratings than control participants (1.67 vs 1.42; P < 0.001), and females also rated their stress levels significantly higher than males (1.8 vs 1.38; P < 0.001). A significant difference between patients with any BSI and control participants existed for history of “shin splints” (Pearson χ2= 28.31; P < 0.001), and females also expressed having shin pain lasting for longer than 4 weeks (Pearson χ2= 8.12; P < 0.001) and more often (Pearson χ2= 5.84; P = 0.02) than males. There was also a significant difference between patients with BSI and control subjects regarding dairy intake (2.25 vs 2.69; F = 6.43; P = 0.01).Conclusion:Findings revealed significant differences between those who reported a BSI relative to healthy athletic adolescents. These differences included body mass index, prior history of shin splints, involvement in weight training, amount of sleep, daily stress, and dairy intake. Preventive measures should be developed to address these areas to reduce the incidence of BSIs in the adolescent population.

Background:The incidence of adolescent overuse injuries, including bone stress injuries (BSIs), is on the rise. The identification of a BSI in the early stages is key to successful treatment. The Shin Pain Scoring System (SPSS) was developed to aid clinicians in identifying patients with a BSI.Hypothesis:The SPSS will correlate with magnetic resonance imaging (MRI) grading of a BSI in an adolescent population.Study Design:Cohort study (diagnosis); Level of evidence, 2.Methods:Enrolled in this study were 80 adolescent high school athletes between the ages of 13 and 18 years participating in a variety of sports with more than 1 week of atraumatic shin pain. The SPSS questionnaire was completed for each participant, and physical examination findings were recorded. Each question and physical examination item was allotted a point value, which totaled 29 points. Radiographs and MRI scans of both lower legs were obtained for each participant. The SPSS score was statistically analyzed using logistic regression, a classification matrix, and a 2 × 2 contingency table to evaluate validity and predictability.Results:Logistic regression analysis of our data determined that 3 categories of SPSS scores provided the highest diagnostic value when compared with MRI grading based on the Fredericson classification (0-4). The SPSS correctly identified 43.5% of injuries for category 1 (MRI grades 0-1), 62.5% for category 2 (MRI grade 2), and 50.0% for category 3 (MRI grades 3-4). Overall, the SPSS correctly identified the degree of BSI in 54.4% of all tibias studied. Binary analysis for validity demonstrated a sensitivity of 96%, specificity of 26%, positive predictive value of 76%, and negative predictive value of 71% for the SPSS relative to the “gold standard” MRI results.Conclusion:The SPSS is a potentially valid method to identify tibial BSIs, given the sensitivity and negative and positive predictive values. It also provides helpful categorization to alert clinicians to the presence of a BSI and direct further diagnostics and/or interventions. The SPSS should be considered as an additional tool to use when evaluating adolescents with atraumatic tibial BSIs.
