BACKGROUND: Clubfoot is one of the most common congenital malformations, but it is also one of the most neglected public health problems among less than five-year-old children, mainly in middle- and low-income countries. Approximately 80% of clubfoot cases are found in low- and middle-income countries. In this study setting, no epidemiological studies have been conducted to assess clubfoot deformity. Due to this gap, the study aimed to assess prevalence, and pattern of congenital club foot among less than 5-year-old children.
METHODS: An institutional-based cross-sectional study was carried out at Black Lion Specialized Hospital at the pediatric orthopedic clinic. The sample size was 261 to determine the prevalence and pattern of congenital clubfoot. Terms like frequency, percentage, and mean were used for data presentation.
RESULTS: A total of 36,303 pediatric patients visited Black Lion Specialized Hospital during the study period, and clubfoot prevalence was 7.2 per 1000. The largest subclassification of congenital clubfoot was idiopathic clubfoot, which accounted for 6.2 per 1000, whereas syndromic clubfoot was 0.3 per 1000, and neuropathic clubfoot was shared at 0.36 per 1000. Most of the cases in this study were bilateral clubfoot, with males having more dominance.
CONCLUSIONS: In the area under investigation, a significant prevalence of congenital clubfoot was observed, especially among male children. The majority of cases were bilateral, with idiopathic clubfoot being the dominant form.

BACKGROUND: Clubfoot, or congenital talipes equinovarus, is a widely recognized cause of disability and congenital deformity worldwide, which significantly impacts the quality of life. Effective management of clubfoot requires long-term, multidisciplinary intervention. It is important to understand how common this condition is in order to assess its impact on the population. Unfortunately, few studies have investigated the prevalence of clubfoot in Saudi Arabia.
OBJECTIVE: To determine the prevalence of clubfoot in Saudi Arabia via the patient population at King Fahad University Hospital (KFUH).
METHODS: This was a retrospective study conducted at one of the largest hospitals in the country and located in one of the most densely populated of the administrative regions.
RESULTS: Of the 7792 births between 2015 to 2023 that were included in the analysis, 42 patients were diagnosed with clubfoot, resulting in a prevalence of 5.3 per 1000 live births at KFUH.
CONCLUSIONS: The observed prevalence of clubfoot was significantly higher than both global and local estimates, indicating a substantial burden in the study population.

BACKGROUND: Congenital talipes equinovarus (clubfoot) is a common musculoskeletal anomaly, with a suspected multifactorial etiopathogenesis. Herein, we used publicly available data to ascertain liveborn infants with clubfoot delivered in Denmark during 1994-2021, and to classify co-occurring congenital anomalies, estimate annual prevalence, and compare clubfoot occurrence with maternal smoking rates, a commonly reported risk factor. Characterizing this nationwide, liveborn cohort provides a population-based resource for etiopathogenic investigations and life course surveillance.
METHODS: This case-cohort study used data from the Danish National Patient Register and Danish Civil Registration System, accessed through the publicly available Danish Biobank Register, to identify 1,315,282 liveborn infants delivered during 1994-2021 in Denmark to Danish parents. Among these, 2,358 infants (65.1% male) were ascertained with clubfoot and classified as syndromic (co-occurring chromosomal, genetic, or teratogenic syndromes) and nonsyndromic (isolated or co-occurring multiple congenital anomalies [MCA]). Annual prevalence estimates and corresponding 95% confidence intervals (CIs) for children with nonsyndromic clubfoot were estimated using Poisson regression and compared with population-based, maternal annual smoking rates obtained from publicly available resources.
RESULTS: Infants most often presented with nonsyndromic clubfoot (isolated = 88.6%; MCA = 11.4%); limb and heart anomalies were the most frequently identified MCAs. Prevalence (per 1,000 liveborn infants) was 1.52 (CI 1.45-1.58) for isolated and 0.19 (CI 0.17-0.22) for MCA clubfoot. Prevalence estimates for both isolated and MCA clubfoot remained relatively stable during the study period, despite marked decreases in population-based maternal smoking rates.
CONCLUSIONS: From 1994 to 2021, prevalence of nonsyndromic clubfoot in Denmark was relatively stable. Reduction in population-level maternal smoking rates did not seem to impact prevalence estimates, providing some support for the suspected multifactorial etiopathogenesis of this anomaly. This nationwide, liveborn cohort, ascertained and clinically characterized using publicly available data from the Danish Biobank Register, provides a population-based clinical and biological resource for future etiopathogenic investigations and life course surveillance.

UNASSIGNED: Clubfoot is among the most common musculoskeletal congenital anomalies. Poor understanding of clubfoot can cause lack of awareness that leads to complications in treating this condition because of late medical intervention. This is considered as a significant public health problem, especially in communities where the burden of clubfoot deformity remains unrecognized. We assessed the level of awareness and knowledge on clubfoot among residents of rural areas and determined the knowledge and attitudes of the public toward the risk factors and general consequences of clubfoot.
UNASSIGNED: This cross-sectional study, conducted from January to July 2021, included the general population of small city and rural area residents. The participants completed a self-administered survey on the web. The questionnaire was pre-tested in a pilot study to ensure comprehension and ease of administration.
UNASSIGNED: Altogether, 41.6% of the participants recognized the scientific name of clubfoot in their native language, whereas 38.9% identified the disorder after they were shown a photograph of it. The most recognized risk factors of clubfoot according to the participants were family history (52.2%), complicated pregnancy (46.5%), and medications (43.4%). Only 8.8% of the participants considered casting the initial treatment of clubfoot.
UNASSIGNED: An individual\'s residential area plays a role in their level of awareness concerning clubfoot. Our results suggest that many educational interventions for clubfoot must be provided in rural areas, particularly regarding therapeutic options and plans of care.

Background: There are few studies on the detection rate by chromosomal microarray analysis (CMA) of the prenatal diagnosis of talipes equinovarus (TE) compared to conventional karyotyping. We aimed to explore the molecular etiology of fetal TE and examine the detection rate by CMA, which provides more information for the clinical screening and genetic counseling of TE. Methods: In this retrospective study, pregnancies diagnosed with fetal TE were enrolled and clinical data for all cases were retrieved from our medical record database, including demographic data for pregnancies, ultrasound findings, karyotype/CMA results, and pregnant and perinatal outcomes. Results: Among the 164 patients, 17 (10.4%) clinically significant variants were detected by CMA. In 148 singleton pregnancies, the diagnostic rate of clinically significant variants was significantly higher in the non-isolated TE group than in the isolated TE group (10/37, 27.0% vs. 6/111, 5.4%, P < 0.001). In twin pregnancies, 1 (6.3%) pathogenic copy number variant was present in the other 16 twin pregnancies. Conclusions: This study demonstrates that CMA is useful for the prenatal genetic diagnosis of fetal TE. Fetal TE with the associated structural malformation correlates with a higher probability of clinically significant variants. This data may aid prenatal diagnosis and genetic counseling for fetal TE.

UNASSIGNED: We aimed to compare our parent-based exercise programem\'s efficacy with the foot abduction brace (FAB) Ponseti manipulation as a retention programme.
UNASSIGNED: We conducted this prospective multicentre cohort study between August 2009 and November 2019. The included children were allocated into one of two groups according to the retention protocol. The Pirani and Laaveg-Ponseti scores were used to assess the feet clinically and functionally. Radiological assessment was performed using standing anteroposterior and lateral radiographs of the feet. We assessed the parents\' satisfaction and adherence to the retention method. SPSS version 25 was used for the statistical analysis.
UNASSIGNED: A total of 1265 feet in 973 children were included. Group A included 637 feet managed with FAB, while group B included 628 feet managed with our retention programme. All patients were followed up to the age of four years. At the final follow-up, Pirani scores in group A participants were excellent, good and poor in 515, 90, and 32 feet, respectivel, while in group B the scores were excellent, good and poor in 471, 110 and 44 feet, respectively. The mean total score of Laaveg-Ponseti was 87.81 (sd 19.82) in group A and 90.55 (sd 20.71) in group B (p = 0.02). Group B participants showed higher satisfaction with the treatment method (p = 0.011) and more adherence to the treatment (p = 0.013).
UNASSIGNED: The deformity\'s recurrence related to the brace\'s non-compliance in the Ponseti method might be reduced by substituting the brace with our home-based daily stretching exercises.
UNASSIGNED: II.
