Meta-Analysis Review
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.

BACKGROUND
The modified Lapidus (ML) is a powerful procedure for correction of hallux valgus (HV) with emerging techniques. Studies considering patient-reported outcomes, radiographic measures, complications, and implant costs are currently limited.
METHODS
Retrospective cohort with prospectively collected Patient Reported Outcome Information System Physical Function (PROMIS-PF) Computerized Adaptive Test (CAT) scores, radiographic parameters (intermetatarsal angle, IMA; hallux valgus angle, HVA; and tibial sesamoid position, TSP), complications, and total operative time and implant costs were reviewed from 2014 to 2019.
RESULTS
Seventy-three feet (68 patients) underwent bunion correction by ML with lag-screw fixation. Median age was 55.8 years (IQR 45.6, 53.9), 4 of 73 (5.5%) were male, 11 of 73 (15.1%) were smokers, and 15 of 73 (20.6%) were diabetic (median HbA1c 6.4% [IQR 6.0, 7.4], none insulin dependent, 5 of 15 with neuropathy). Complications included 6 of 73 (8.2%) wound issues resolved with topical or oral treatment, 9 of 73 (12.3%) painful or broken hardware requiring hardware removal. Two of 73 (2.7%) had persistent pain despite union. One of 73 (1.4%) was overcorrected and required first MTP arthrodesis. Of 3 nonunions (2.7%), 1 resolved with corrected hypothyroidism, 1 was asymptomatic and required no treatment, 1 had a hallux valgus recurrence and sought revision surgery elsewhere. Preoperative radiographic angles were HVA 35 degrees, IMA 14 degrees which improved at final postoperative follow up to HVA 10 degrees, IMA 6 degrees. Tibial sesamoid position improved from 6.05 ± 1.00 to 2.22 ± 1.38. Thirty-two patients had preoperative and 42 had 1-year postoperative outcomes. PROMIS-PF (51% collection rate) was 43 (IQR 37,52) preoperatively, 37 (31, 39) at 6 weeks, 46 (42, 51) at 3 months, and 49 (41, 53) at >360 days postoperatively. The drop in PROMIS-PF between preoperative and 6 weeks and the rise from 6 weeks to 3 months were statistically significant. Pre- and postoperative PROMIS-PF scores were not significantly different. Implant cost averaged US$146.
DISCUSSION/CONCLUSION
We report low complication rates and costs with high patient postoperative functional and radiographic outcomes. PROMIS-PF decreased acutely postoperatively but recovered and maintained high levels by 3 months postoperatively.

BACKGROUND
Approximately 1 in 4 adults will develop hallux valgus (HV). Up to 80% of adult Internet users reference online sources for health-related information. Overall, with the high prevalence of HV combined with the numerous treatment options, we believe patients are likely turning to Internet search engines for questions relevant to HV. Using Google's people also ask (PAA) or frequently asked questions (FAQs) feature, we sought to classify these questions, categorize the sources, as well as assess their levels of quality and transparency.
METHODS
On October 9, 2022, we searched Google using these 4 phrases: "hallux valgus treatment," "hallux valgus surgery," "bunion treatment," and "bunion surgery." The FAQs were classified in accordance with the Rothwell Classification schema and each source was categorized. Lastly, transparency and quality of the sources' information were evaluated with the 's (JAMA) Benchmark tool and Brief DISCERN, respectively.
RESULTS
Once duplicates and FAQs unrelated to HV were removed, our search returned 299 unique FAQs. The most common question in our sample was related to the evaluation of treatment options (79/299, 26.4%). The most common source type was medical practices (158/299, 52.8%). Nearly two-thirds of the answer sources (184/299; 61.5%) were lacking in transparency. One-way analysis of variance revealed a significant difference in mean Brief DISCERN scores among the 5 source types, (4) = 54.49 ( < .001), with medical practices averaging the worst score (12.1/30).
CONCLUSION
Patients seeking online information concerning treatment options for HV search for questions pertaining to the evaluation of treatment options. The source type encountered most by patients is medical practices; these were found to have both poor transparency and poor quality. Publishing basic information such as the date of publication, authors or reviewers, and references would greatly improve the transparency and quality of online information regarding HV treatment.

Review
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.

BACKGROUND
Hallux valgus is a common condition with a complex etiology resulting in numerous treatment options. Recurrence of the deformity can occur following correction. Surgical technique and possibly also postoperative care play a role in reducing recurrence rates. This article highlights a postoperative surgical dressing technique which allows for semirigid support during the immediate postoperative period.
METHODS
A wooden tongue depressor placed along the medial border of the hallux comprises the primary support for the dressing. The rigidity of the tongue depressor allows for the hallux to be drawn toward the depressor, encouraging neutral alignment of the hallux. Dressings are removed 2 weeks postoperatively, with new dressings applied in similar fashion and maintained in place until 6 weeks postoperatively.
RESULTS
Based upon our observations, our surgical dressing technique provides sufficient support following hallux valgus correction surgery while being straightforward to replicate without the need for frequent dressing changes. The dressing materials are of negligible cost and are typically readily available. No associated wound complications have been observed.
CONCLUSIONS
We present an easily replicable and affordable option for postoperative hallux valgus correction surgical dressings.

OBJECTIVE
The aim of this study was to analyze the effect of Scarf and Chevron combined with Akin on a postoperative balance of patients with moderate to severe foot bunion.
PATIENTS AND METHODS
One hundred (100 feet) patients with moderate to severe bunion cysts treated at our hospital from January 2019 to January 2022 were retrospectively selected as subjects and divided into 2 groups according to their surgical procedure. The control group received Scarf combined with Akin, and the study group received Chevron combined with Akin. Oxidative stress mediators [late oxidized protein product (AOPP), lipid peroxide (LPO)], inflammatory factors [interleukin-1β (IL-1β), procalcitonin (PCT)], Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal joint angle (DMAA) Angle, ankle-hind foot American Orthotic Foot and Ankle Association (AOFAS) score, pain visual analog scale (VAS) score and balance Berg Balance Scale (BBS) score were compared between the two groups before and after surgery. The effectiveness and safety of the operation were compared.
RESULTS
The levels of AOPP and LPO in the study group decreased most significantly, t=1.081 and 10.850, p=0.001; the levels of IL-1β and PCT in the study group increased most significantly, t=16.970 and 12.260, p=0.001; the indexes of HVA, IMA, and DMAA in the study group increased significantly, t=11.890, 11.550, and 12.670, p=0.001; the AOFAS and BBS scores in the study group increased significantly, while the VAS score in the study group decreased significantly, t=14.760, 13.580, 5.994, p=0.001; the total effective rate of treatment in the study group was the highest, χ²=6.960, p=0.00; the total incidence of complications in the study group was the lowest, χ²=1.834, p=0.175.
CONCLUSIONS
Chevron combined with Akin is more effective than Scarf combined with Akin in treating moderate to severe foot bunion, the former is more minimally invasive and has a better effect in promoting postoperative balance recovery.

Clinical Trial
BACKGROUND
Hallux valgus (HV) is a common foot deformity that manifests with increasing age, especially in women. The associated foot pain causes impaired gait and decreases quality of life. Moderate and severe HV is a deformity that is characterized by the involvement of lesser rays and requires complex surgical treatment. In this study, we attempted to develop a procedure for this condition.
AIM
To analyse the treatment results of patients who underwent simultaneous surgical correction of all parts of a static forefoot deformity.
METHODS
We conducted a prospective clinical trial between 2016 and 2021 in which 30 feet with moderate or severe HV associated with Tailor's bunion and metatarsalgia were surgically treated a new method involving surgical correction of all associated problems. This method included a modified Lapidus procedure, M2M3 tarsometatarsal arthrodesis, intermetatarsal fusion of the M4 and M5 bases, and the use of an original external fixation apparatus to enhance correction power. Preoperative, postoperative, and final follow-up radiographic data and American Orthopaedic Foot and Ankle Society (AOFAS) scores were compared, and values < 0.05 were considered to indicate statistical significance.
RESULTS
The study included 28 females (93.3%) and 2 males feet (6.7%), 20 (66.7%) of whom had a moderate degree of HV and 10 (33.3%) of whom had severe deformity. M2 and M3 metatarsalgia was observed in 21 feet, and 9 feet experienced pain only at M2. The mean follow-up duration was 11 months. All patients had good correction of the HV angle [preoperative median, 36.5 degrees, interquartile range (IQR): 30-45; postoperative median, 10 degrees, IQR: 8.8-10; follow-up median, 11.5 degrees, IQR: 10-14; < 0.01]. At follow-up, metatarsalgia was resolved in most patients (30 5). There was a clinically negligible decrease in the corrected angles at the final follow-up, and the overall AOFAS score was significantly better (median, 65 points, IQR: 53.8-70; 80 points, IQR: 75-85; < 0.01).
CONCLUSION
The developed method showed good sustainability of correction power in a small sample of patients at the one-year follow-up. Randomized clinical trials with larger samples, as well as long-term outcome assessments, are needed in the future.

A 28-Year-Old Woman with Down Syndrome, Congenital Heart Disease, and a History of Knee Surgery and Plantar Fasciitis, with Hallux Abducto Valgus (Bunion) and Lapiplasty Three-Dimensional Correction Surgery.
BACKGROUND Tarsometatarsal joint (TMJ) arthrodesis is common method used for correcting hallux abductus valgus (HAV). Its popularity has grown due to studies revealing HAV's triplanar deformity with frontal plane rotation. This case report presents a 28-year-old woman with Down syndrome, congenital heart disease, and a history of knee surgery and plantar fasciitis, with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. CASE REPORT Examination revealed severe foot deformities, and radiographic studies confirmed the condition. A surgical intervention was planned, and the patient's cardiologist confirmed she was fit for the procedure. The modified Lapidus technique with frontal plane rotational correction included realigning the metatarsal joint, resecting spurs, osteosynthesis material, and arthrosis in the sinus tarsi. After surgery, the patient underwent a recovery period without support for 8 weeks and received appropriate medical care. Radiographs showed successful alignment, and the patient gradually resumed her daily activities. The patient had an uneventful recovery, and postoperative radiographs showed good alignment in all planes. CONCLUSIONS The hyperlaxity associated with Down syndrome makes the incidence of HAV more frequent, and TMJ fusion is preferable to correction by osteotomy. The modified Lapidus technique with frontal plane rotational correction could be a good technique to achieve satisfactory correction in patients with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. TMJ fusion is indicated when severe or recurrent rotational component is observed in X-rays.

OBJECTIVE
To design appropriate orthosis for hallux valgus, a difficult foot condition that affects a quarter of the body's bones, we need to clarify the numerical biomechanical features, which have not been established in previous biomechanical studies. Therefore, we constructed a finite element model of the bunion foot to investigate the orthopaedic force compensation mechanism.
METHODS
A patient with moderate hallux valgus was recruited. CT imaging data in DICOM format were extracted for three-dimensional foot model reconstruction. In conjunction with the need for rapid design of bunion orthosis, a metatarsal force application sizing method based on an orthogonal test design was investigated. The orthogonal test design was used to obtain the hallux valgus angle (HVA) and the inter metatarsal angle (IMA) data for different force combinations. Based on the extreme difference analysis and analysis of variance of the test results, the influence of different force combinations on the bunion angle was quickly determined.
RESULTS
The results showed that the stress concentration occurred mainly in the first metatarsal bone. The distribution trend was in the medial and lateral middle of the bone and gradually decreased to the dorsal base of the bone body. The greatest stress occurs in the cartilage between the phalanges and metatarsals. In 25 groups of simulation experiments, HVA was reduced from 27.7° to 13°, and IMA was reduced from 12.5° to 7.3°.
CONCLUSION
Applying detailed orthopaedic force collocation to the first metatarsal column can effectively restore the mechanics and kinematics of hallux valgus, and provide a reference for the treatment of bunion valgus and the design of orthopaedic devices.
