Low Energy, Lateral Ankle Injuries in Pediatric and Adolescent Patients: A Systematic Review of Ankle Sprains and Nondisplaced Distal Fibula Fractures

Lateral ankle injuries are one of the most common musculoskeletal injuries sustained by pediatric and adolescent athletes. These injuries can result in significant time lost from competition, affect performance when returning to play, and represent a significant burden on the health care system as a whole. The purpose of this study was to systematically review the literature on the diagnosis, treatment, and prevention of acute lateral ankle injuries and their chronic effects in pediatric and adolescent athletes (younger than 19 y).Methods:This systematic review was conducted according to PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) guidelines between September and December 2018. PubMed and Google Scholar were systematically searched using the search terms: ("distal fibula fracture" OR "ankle sprain") AND ("youth" OR "pediatric" OR "adolescent"). All authors participated in article review (N=172) for relevance and age restrictions in which 30 met the inclusion criteria.Results:Thirty articles met inclusion criteria [Levels of Evidence I to IV (I: n=4, II: n=16, III: n=9, and IV: n=1)] including distal fibula fracture diagnosis and treatment, and risk factors, prevention, and chronic sequela of lateral ankle injuries in pediatric and adolescent patients.Conclusions:Low-energy, lateral ankle injuries are common in pediatric and adolescent patients, yet underrepresented in the medical literature. There is a lack of high-quality literature on diagnosis, treatment, and outcomes after Salter-Harris I distal fibula fractures. Available literature, however, suggests that there remains over diagnosis and over treatment of presumed Salter-Harris I distal fibula fractures. Adolescent ankle sprains dominate the available literature likely due to the high recurrence rate. Youth athletes and coaches should address risk factors and engage in injury prevention programs to prevent and minimize the effect of acute lateral ankle injuries.Levels of Evidence:Level III - Systematic review.
