A Systematic Review and Meta-Analysis of the Prevalence of Hallux Valgus in the General Population.

The objective of this systematic review was to determine the prevalence of hallux valgus (HV) in the general population by conducting a review and meta-analysis of existing studies. Published articles on the incidence of HV were systematically searched and evaluated on reputable medical databases such as PubMed. The keywords "the prevalence of hallux valgus and/or bunions"were used to create the search syntax on the various databases. Data were gathered on prevalence, population under study, and methodology. A total of 11 articles that met the search criteria were identified and included in this review for a total of 10,886 participants across the studies. The pooled prevalence of HV across the studies was3.75 (95% confidence interval = 0.388-0.517). Therefore, the prevalence varied widely across the studies reviewed. Prevalence was observed to be high among females and increased with risk factors such as body mass index, which were identified as significant across the studies. This review was limited by insufficient data and the lack of a standard HV diagnosis method. Therefore, a standard HV diagnosis tool is recommended.
