Epidemiology of High Ankle Sprains: A Systematic Review.

Syndesmotic sprains or high ankle sprains are reported to be associated with increasing morbidity and time loss. The aim of this study was to critically appraise literature on epidemiology of syndesmotic sprains through systematic review of published literatures. A systematic review was conducted online for literature published in English using PubMed and Google Scholar, as per PRISMA guidelines up to April 30, 2019. Predefined eligibility criteria were applied, and the data thus compiled were analyzed. A total of 26 studies were found to be eligible, of which three-fourths involved sporting population. Considerable inconsistency in assessment procedure reporting, injury and injury severity definition with variable unit measures used to describe incidence or injury rate was observed. Meta-analysis and intra- and intersports comparison could not be performed owing to the study heterogeneity and methodological variability. There is a need for standardization in future research, specifically with regard to injury assessment and reporting, demanding heightened awareness and improved diagnostic modalities, as injury epidemiology is integral to the overall injury-prevention conundrum. Systematic review, Level III.
