Abstract
BACKGROUND Though hallux valgus is a common foot deformity, the integrated information on its global prevalence and incidence is relatively lacking. The aim of this research was to assess the global prevalence and incidence of hallux valgus, thus providing reliable data reference for clinical practice. METHODS A systematic review of global hallux valgus research publications concerning its prevalence and incidence was performed based on six electronic databases ((PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), China Online Journals and CQVIP)) from their inception to November 16, 2022. The search terms included "hallux valgus or bunion and prevalence or incidence or epidemiology." All languages were included. Data were extracted by country, continent, age group, gender and other information. The risk of bias was assessed by the Joanna Briggs Institute Critical Appraisal Instrument for Studies Reporting Prevalence Data by using random-effects models to synthesize available evidence. RESULTS A total of 45 studies were included in the meta-analysis. The overall pooled estimated prevalence was 19% (95% CI, 13% to 25%) (n=186,262,669) for hallux valgus. In subgroup meta-analyses, the prevalence of hallux valgus was 21.96% (95% CI, 10.95% to 35.46%) in Asia, 3% (95% CI, 0% to 15%) in Africa, 18.35% (95% CI, 11.65% to 26.16%) in Europe, 29.26% (95% CI, 4.8% to 63.26%) in Oceania, and 16.1% (95% CI, 5.9% to 30.05%) in North America, respectively. The pooled prevalence of hallux valgus by gender was 23.74% (95% CI, 16.21% to 32.21%) for females and 11.43% (95% CI, 6.18% to 18%) for males. The prevalence was 11% (95% CI, 2% to 26%) in individuals younger than 20 years old, 12.22% in adults aged 20-60 years (95% CI, 5.86% to 20.46%) and 22.7% in elderly people aged over 60 years (95% CI, 13.1% to 33.98%). CONCLUSION This research provided the global prevalence and incidence of hallux valgus in terms of its spatial, temporal, and population distribution. The global estimated pooled prevalence and incidence of hallux valgus was 19%. A higher prevalence of hallux valgus was found in females, Oceania countries, and among people aged over 60 years. Due to the high heterogeneity of the included studies, the findings should be interpreted with caution.

Abstract
PURPOSE Biomechanical study of fixation methods post hallux valgus minimally invasive osteotomy using finite element technology hasn't been reported. This study aimed to compare maximum displacement and stress distribution of osteotomy ends after minimally invasive osteotomy fixed by bandage, Kirschner wire, Herbert screw. METHODS Foot CT images of a patient with mild-moderate hallux valgus were collected. Three-dimensional finite element model of hallux valgus was established through CT image. This study simulated bandage, Kirschner wire and Herbert screw fixation, and analyzed maximum displacement and stress distribution of osteotomy ends in plantar flexion position of foot after fixation. RESULTS Maximum equivalent stress of osteotomy end fixed with bandage, Kirschner wire, Herbert screw was 7.8615, 14.253, 8.3156 MPa, respectively. Total displacement of osteotomy end fixed by bandage, Kirschner wire, Herbert screw was 0.26,896, 0.022,779, 0.029,195 mm, respectively. Maximum stress of Kirschner wire and Herbert screw near osteotomy end was 154.7 and 46.404 MPa, respectively. Fixation strength and stability of Kirschner wire and Herber screw were better than bandage. Kirschner wire had stress concentration phenomenon, with potential fracture risk. Stress of Herbert screw was evenly distributed around osteotomy end, and there was a certain stress concentration, playing an important role in maintaining fracture end stability. CONCLUSIONS Herbert screw showed good fixation strength and stability, and stress distribution was uniform, which can well maintain stability of minimally invasive osteotomy ends. Findings of this study would provide a theoretical basis for selection of fixation methods after clinical minimally invasive osteotomy for hallux valgus.

[PMID: 36269073 DOI: 10.1080/00140139.2022.2139415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 10/17/2022] [Indexed: 06/16/2023]
Abstract
The forefoot is the foot part most affected by ill-fitting shoes. Footwear fitting considers the measurements of length, width, and arch length. Toe shape has not yet been used in sizing feet and fitting shoes. This study aims to investigate the variation in toe shape, as measured by the hallux valgus angle. An automatic and reproducible hallux valgus angle measuring method using 3D foot scans with no palpation markers is proposed and applied to about half a million samples collected across North America, Europe, and Asia. The measuring method is robust and can detect the medial contour along the proximal phalanx even in extreme cases. The hallux valgus angle has a normal distribution with long tails on both sides in the general population. Large dispersions of HVA values were observed for both genders and in all three geographical regions. Practitioner summary: The hallux valgus angle has a broad distribution in the general population. Females have larger hallux valgus angles than males, and people from Asia have larger hallux valgus angles than people from North America and Europe. Shoe toe boxes should be designed to fit the actual shapes of shoppers' toes. The proposed method for measuring HVA opens a new opportunity to study the causal relationship between shoe wearing habits and HVA on a large scale.

Abstract
Korean cosmetics sales workers in department stores face harmful working environments, including limited restroom access, working long hours in a standing position, and customer violence. This study investigated health disparities between cosmetics saleswomen and the general population of working women in South Korea. We assessed the prevalence of health indicators, including physician-diagnosed disease, using a cross-sectional survey of 860 Korean cosmetics saleswomen in September 2018. Health indicators of cosmetics saleswomen were compared to those of general working women from the nationally representative datasets (e.g., National Health Insurance Service-National Sample Cohort). We estimated age-standardized prevalence ratios (SPRs) for health outcomes, including physical, mental, and health-related behavioral conditions. Cosmetics saleswomen were more likely to be diagnosed or treated for physical and mental conditions (e.g., cystitis SPR: 4.03, 95% confidence interval [CI]: 3.48-4.65; plantar fasciitis SPR: 23.48, 95% CI: 18.12-29.93; varicose vein SPR: 38.41, 95% CI: 32.18-45.49; and depression SPR: 11.18, 95% CI: 8.53-14.40) compared to general working women. Prevalence of smoking and hazardous alcohol consumption was also higher among cosmetics saleswomen than those of general women workers. Given our findings, further research is needed to identify work-related risk factors that could deteriorate cosmetic sales workers' health in South Korea.
