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...

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...

BACKGROUND: Hallux valgus (HV) is commonly treated with proximal or distal first metatarsal osteotomy. Despite good correction, these procedures have inherent risks such as malunion, nonunion, metatarsal shortening, loss of fixation, and avascular necrosis. Suture button fixation has been used for HV treatment. It avoids the risks of corrective osteotomies while maintaining reduction of the intermetatarsal angle (IMA). The goal of this study was to assess the radiographic and functional outcomes of patients undergoing HV correction with a distal soft tissue procedure and proximal suture button fixation...

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...

Minimally invasive surgery (MIS) has gained popularity for hallux valgus correction in the adult population. The advantage of reproducibility of this procedure can aid in lower operating room costs, quicker recovery, and fewer complications. The purpose of this retrospective study was to compare preoperative versus postoperative foot widths in patients that underwent MIS hallux valgus correction. The average preoperative foot width was 101.1 ± 5.67 mm and postoperatively the foot width measured at 12-month follow-up was 95...

The use of staples has been shown to be a reasonable fixation technique to achieve stability of a 1st MTPJ arthrodesis. Although it has been shown to be a weaker construct than crossed screws or plate and screw combinations, their ease of insertion, low profile, and stability make them a desirable choice for 1st MTPJ arthrodesis fixation. However, because of this relative weakness, the question remains whether immediate weight bearing when using staples is advisable. The aim of this study is to determine whether the use of 2 nickel-titanium alloy (NITINOL) staples, placed at 90 degrees to one another is a stable enough construct to support full, immediate weight bearing following 1st MTPJ arthrodesis...

BACKGROUND: Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome, is an acute, self-limiting vasculitis of unknown aetiology that mainly involves the medium and small arteries and can lead to serious cardiovascular complications, with a 25% incidence of coronary artery aneurysms. Periton-Sillar abscesses are a rare symptom of KD and is easily misdiagnosed at its early stages. CASE SUMMARY: A 5-year-old boy who presented to a community hospital with a 3-d fever, difficulty in opening his mouth, and neck pain and was originally treated for throat infection without improvement...

BACKGROUND: The purpose of this systematic review is to examine the learning curve associated with minimally invasive surgery (MIS) for the treatment of hallux valgus (HV). METHODS: A systematic review was performed using PubMed, ScienceDirect, Web of Science, CINAHL and MEDLINE databases from database inception to February 16th, 2023. Inclusion criteria was articles with level of evidence I-III, any outcomes associated with learning curve, minimally invasive surgery, and diagnosis of hallux valgus' in adult patients...

BACKGROUND: Evolving evidence and improved instrumentation have led to increasing importance of minimally invasive surgery (MIS) surgery in the treatment of hallux valgus deformity. This study aims to investigate the current trends of the practice of MIS hallux valgus surgery in the Asia Pacific region. METHOD: A survey was sent via email to 30 fellowship-trained foot and ankle surgeons in 11 Asia Pacific countries, all registered with their respective national orthopaedic societies...

BACKGROUND: Minimally invasive chevron Akin osteotomy (MICA) has become increasingly common and is compatible with the traditional open approaches for hallux valgus correction. However, it is impeded by concerns regarding the steep learning curve, increased radiation exposure and some specific complications. No standardized method for identifying a learning curve exists. We used a reproducible mathematical model to accurately define the learning curve of MICA with a focus on fluoroscopy time, procedure duration and complications rate...

BACKGROUND: Among the numerous surgical interventions for correcting hallux valgus deformity in skeletally immature patients, hemiepiphysiodesis is a simple technique with a low complication rate yet its effectiveness remains unclear. This systematic review evaluates hemiepiphysiodesis of the first metatarsal for treating juvenile hallux valgus (JHV) deformities with respect to radiological outcomes, postoperative clinical outcomes, and postoperative complications. METHODS: EMBASE, MEDLINE, PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) database were searched from inception to September 15th, 2022, for studies investigating hemiepephysiodesis for JHV and its effect on clinical and radiological outcomes...

BACKGROUND: Hallux valgus is a common deformity encountered but remains a complex clinical entity. Fourth-generation minimally invasive surgery (MIS) techniques consisting of a percutaneous distal metatarsal transverse osteotomy combined with an Akin osteotomy have been used to address mild to severe hallux valgus deformities. The benefits of an MIS approach include improved cosmesis, faster recovery, lower opiate requirement, immediate weightbearing, and favorable outcomes relative to a traditional, open procedure...

Diabetic foot ulcer (DFU) is one of the most serious complications of diabetes. Elderly diabetic patients are a high prevalence of diabetic foot ulcers, and their high recurrence, disability, and mortality rates impose a heavy economic burden on families and society. This paper reports a case of an elderly patient with a diabetic foot ulcer who was admitted in April 2007 and discharged after recovery from comprehensive diabetic foot treatment. Due to intermittent foot care and lack of home care, the patient's foot ulcers recurred after repeated healing during home rehabilitation, eventually resulting in the amputation of the right bunion...

BACKGROUND: The morphology of foot joints is widely accepted as a significant factor in the development of various foot disorders. Nevertheless, the role of the first tarsometatarsal joint (TMT1) morphology in hallux valgus (HV) remains unclear, and its impact on TMT1 instability has not been fully explored. This study aimed to investigate the TMT1 morphology and its potential correlation with HV and TMT1 instability. METHODS: Weightbearing computed tomography (WBCT) scans of 82 consecutive feet with HV and 79 controls were reviewed in this case-control study...

Plantar plate positioning has been demonstrated as biomechanically superior. However, some operators remain resentful about the morbidity of the surgical approach. To provide improved plate fixation for first tarsometatarsal joint arthrodesis with respect to the tibialis anterior tendon, a medio-plantar plate was developed. The purpose of this biomechanical study was to compare its construct stability to that of a plantar plate construct. Twelve pairs of fresh frozen human specimens were used in a matched pair test...

INTRODUCTION: Overcorrection is a possible complication of clubfoot treatment, whose prevalence varies from 5 to 67%. Overcorrected clubfoot usually presented as a complex flatfoot with different degrees of hindfoot valgus, flat top talus, dorsal bunion, and dorsal navicular subluxation. The management of clubfoot overcorrection is challenging, and both conservative and surgical treatments are available. This study aims to present our experience in the surgical management of overcorrected clubfoot and to provide an overview of actual treatment options for each specific sub-deformity...

Hallux valgus is a common progressive forefoot deformity. Although open techniques have shown good outcomes, no technique has been shown to be superior to other techniques. The current third generation of minimally invasive Chevron-Akin (MICA) technique features a percutaneous procedure with a stable internal fixation. The technique used in this study resulted in stable internal fixation; however, 1 screw was used in intramedullary fashion in the majority of cases. The purpose of this study is to review the early outcomes of MICA...
