Birth prevalence of congenital talipes equinovarus in low- and middle-income countries: a systematic review and meta-analysis

Reliability of Percutaneous Achilles Tenotomy in the Treatment of Idiopathic Clubfoot

BACKGROUND

Talipesequinovarus is a congenital ankle/foot malformation that commonly affects newborns. In its treatment using the Ponseti method, an Achilles tenotomy is frequently needed to correct residual equinus deformity. Percutaneous (PC) tenotomy is the most commonly used technique and needs to be thoroughly evaluated. The question we needed to answer was: "Does PC Achilles tenotomy result in complete tendon sectioning"?

METHODS

This clinical study included 56 idiopathic clubfeet in 36 patients who presented during the first 6 months of life and were treated with Ponseti manipulation and casting followed by PC Achilles tenotomy. PC tenotomy was done under general anesthesia, and Thompson's calf squeeze test was performed intraoperatively just after tenotomy. In case of a negative test (ie, ankle plantar flexion with calf squeeze), the percutaneous incision was extended to assess the cause of the negative test.

RESULTS

Forty-nine feet (87.5%) had a complete tenotomy, as evidenced by a positive Thompson's calf squeeze test. While 7 feet (12.5%) showed a negative test, and therefore the percutaneous incision was extended and all were found to have an incompletely divided Achilles tendon. The tendons were then completely divided, after which Thompson's test became positive in all.

CONCLUSION

Percutaneous Achilles tenotomy is a reliable procedure, but was found to result in incomplete tendon sectioning in 12.5% of cases, affecting the range of ankle dorsiflexion. Thompson's squeeze test is reliable in picking up cases of incomplete tenotomy after the PC technique, and in these cases the incision should be extended for complete sectioning.

Exome sequencing of 1190 non-syndromic clubfoot cases reveals HOXD12 as a novel disease gene

BACKGROUND

Clubfoot, presenting as a rigid inward and downward turning of the foot, is one of the most common congenital musculoskeletal anomalies. The aetiology of clubfoot is poorly understood and variants in known clubfoot disease genes account for only a small portion of the heritability.

METHODS

Exome sequence data were generated from 1190 non-syndromic clubfoot cases and their family members from multiple ethnicities. Ultra-rare variant burden analysis was performed comparing 857 unrelated clubfoot cases with European ancestry with two independent ethnicity-matched control groups (1043 in-house and 56 885 gnomAD controls). Additional variants in prioritised genes were identified in a larger cohort, including probands with non-European ancestry. Segregation analysis was performed in multiplex families when available.

RESULTS

Rare variants in 29 genes were enriched in clubfoot cases, including PITX1 (a known clubfoot disease gene), HOXD12, COL12A1, COL9A3 and LMX1B. In addition, rare variants in posterior HOX genes (HOX9-13) were enriched overall in clubfoot cases. In total, variants in these genes were present in 8.4% (100/1190) of clubfoot cases with both European and non-European ancestry. Among these, 3 are de novo and 22 show variable penetrance, including 4 HOXD12 variants that segregate with clubfoot.

CONCLUSION

We report HOXD12 as a novel clubfoot disease gene and demonstrate a phenotypic expansion of known disease genes (myopathy gene COL12A1, Ehlers-Danlos syndrome gene COL9A3 and nail-patella syndrome gene LMX1B) to include isolated clubfoot.

Reproducibility of pop sensation, Thompson sign in achillotomy, and final Pirani score to predict clubfoot relapse: Achillotomy clinical signs and Pirani predictive ability

Ultrasound (US) can guide and confirm percutaneous release of the achilles tendon in the clubfoot. However, this technique may not always be available; therefore, surgeons' reported feelings of tendon release ("click" or "pop") and the Thompson sign could demonstrate that they are sensitive and reliable for confirming complete tendon release. The purpose of this study was to compare the reproducibility of clinical maneuvers that aim to detect the reported "click" or "pop" sensation by the surgeon and the Thompson sign after surgical release in percutaneous achilles tenotomy compare with US in patients with clubfoot. A cross-sectional reproducibility study of consecutive patients with idiopathic clubfoot was conducted. All the patients were scheduled to undergo tenotomy in the operating room using the standard percutaneous achilles tenotomy technique under sedation. The surgeon's reported surgical sensation ("click" or "pop") and Thompson signs were compared to the US assessment of the cut. The final Pirani score was used to predict recurrence risk and was correlated with the number of plaster casts and age. Forty-five feet were affected in 30 patients. Eighteen (60%) men. Age range: 1 to 60 months. The sensation of "click" or "pop" was recorded in 38 patients, and complete release was confirmed by US in 37 patients, for a sensitivity (Se) of 0.95 and specificity (Sp) of 0.63. Thompson signs were positive in 33 and 36 patients at 2 evaluations, with Se values of 0.87 and 0.92 and Sp values of 0.88 and 0.75, respectively. The Pirani final score, a predictor of recurrence risk, had an area under the curve of 0.80 (95% CI = 0.63-0.97; P = .005), Se = 0.78, and Sp = 0.56, with a cutoff point of 2.75. The feeling of achilles tendon release and Thompson sign had high sensitivity, prevalence, accuracy, and posttest probability. The confirmation of tendon release based on clinical signs could prevent the use of US.

A thorough analysis of data on the correlation between COL9A1 polymorphisms and the susceptibility to congenital talipes equinovarus: a meta-analysis

BACKGROUND

Congenital talipes equinovarus (CTEV) is a prevalent pediatric deformity with a multifactorial etiology. The objective of this meta-analysis was to explore the association between genetic variations in COL9A1 and the susceptibility to CTEV.

METHODS

A comprehensive analysis of pertinent literature released before November 15, 2023, in electronic bibliographic databases was carried out. The importance of the connection was clarified through odds ratios (ORs) with 95% confidence intervals (CIs), utilizing random or fixed-effects models depending on study heterogeneity. Statistical analysis was executed using Comprehensive Meta-Analysis software (Version 4.0).

RESULTS

A total of eight case-control studies involving 833 CTEV patients and 1280 healthy individuals were included in the analysis. Among these, four studies investigated the rs1135056 variant, encompassing 432 CTEV cases and 603 controls; two studies examined the rs35470562 variant, with 189 CTEV cases and 378 controls; and two studies explored the rs592121 variant, including 212 CTEV cases and 299 controls. The results revealed a significant association between the rs1135056 and rs35470562 polymorphisms in the COL9A1 gene, suggesting an increased risk of CTEV in the overall population. Conversely, no such association was found for the rs592121 variant.

CONCLUSION

Our findings reveal a substantial association between the genetic variants COL9A1 rs1135056 and rs35470562 and susceptibility to CTEV. Conversely, the variant rs592121 did not exhibit any corresponding link. However, the limitations imposed by the small study population have compromised the statistical reliability and generalizability of the results.

Can the Achilles tendon regenerate completely following percutaneous tenotomy in older children with clubfoot?

PURPOSE

The aims of the study were to document the outcomes of percutaneous Achilles tenotomy (pAT) performed in older children with clubfoot, by assessing the clinical, functional and ultrasonographic evidence of Achilles tendon regeneration.

METHODS

A retrospective case series of older children with clubfoot treated between August 2011 and July 2020 was studied. Clinical assessment of ankle range of motion and calf strength, functional assessment of triceps surae muscle endurance by single leg heel-rise test, and ultrasonographic assessment of Achilles tendon echotexture and dimensions to assess tendon regeneration were performed.

RESULTS

Percutaneous Achilles tenotomy was performed on 31 children (48 clubfeet) at a mean age of 5.24 ± 2.14 years (1-10.2 years). At a mean follow-up of 4.86 ± 1.97 years, all children demonstrated normal calf strength with mean dorsiflexion range of 13.64° (0-25°) and mean plantarflexion range of 37.95° (10-40°). The heel-rise endurance test was completed by 27 children with mean 25.85 heel rises/minute (range 17-30) and mean height of heel rise of 6.29 cm (range 4-10 cm). Normal fibrillar tendinous echotexture with homogenous echogenicity was seen on ultrasonography in 41 feet (85.4%) with mean tendon width of 9.7 mm (3.3-16 mm) and thickness of 5.1 mm (1.8-15 mm), comparable with unaffected feet.

CONCLUSIONS

Clinical, functional and ultrasonographic parameters unequivocally demonstrate complete regeneration of the Achilles tendon, when pAT is performed in older children with delayed-presenting idiopathic clubfoot treated using Ponseti principles.

Assessing the Influence of Age, Weight, and Pirani Score on the Number of Casts During the Initial Phase of Clubfoot Treatment Using the Ponseti Method: A Prospective Study

Background

Clubfoot, also known as congenital talipes equinovarus is a prevalent childhood ailment that, if untreated, can lead to long-term discomfort and impairment. The Ponseti technique, aimed at achieving corrected foot positioning, is widely accepted. This study investigated the influence of clubfoot severity (Pirani score), patient age, and initial manipulation and casting weight on the overall number of casts needed for effective treatment.

Methods

A prospective study was carried out involving 40 idiopathic clubfoot patients where manipulation and casting were performed following the Ponseti method. Patient age, weight, and foot Pirani score were evaluated concerning the total number of casts needed to achieve 70° of abduction.

Results

The majority of participants were male infants aged 4-6 months, with a median age of 4.5 months. Half of them weighed between 3.00 and 4.99 kg at their first hospital visit, with a median weight of 3.20 kg. Bilateral clubfoot involvement was common (57.5%). Children with Pirani HFCS 2.0-3 often required percutaneous tenotomy (87.5%, p value 0.05). On average, patients needed 5 casts (range 3-9). The mean total Pirani scores were 4.71 for the right foot and 4.61 for the left foot. The study reported a positive correlation between higher total Pirani scores and the required number of casts.

Conclusions

The Pirani scoring system is highly accurate in assessing clubfoot severity and predicting treatment success. It emerged as the single most significant predictor for both the total number of casts and the need for percutaneous tenotomy.

Epidemiological characterization of clubfoot: a population-based study of a surveillance program in Colombia

Clubfoot is a common musculoskeletal congenital abnormality, with a prevalence of 5-20 cases per 10 000 live births in low to middle-income countries. If left untreated, clubfoot causes severe consequences for the child: gait disturbances, reduced quality of life, and limited work opportunities. Our objective was to characterize clubfoot and determine its prevalence and associated risk factors in Bogotá and Cali, Colombia, from 2002 to 2020. A retrospective case-control study design was employed, analyzing data from birth defect reports provided by the Program for the Prevention and Follow-up of Congenital Defects and Orphan Diseases surveillance system. Cases included live births or stillbirths with clubfoot, while controls consisted of infants without congenital abnormalities, matched in terms of birth date and hospital. Prevalence was calculated considering a 95% confidence interval using Poisson distribution, and risk factors were assessed through adjusted odds ratios obtained by logistic regression model. Of 558 255 births, 861 cases of clubfoot were identified, 48.20% were postural clubfoot, and 15 cases were syndromic clubfoot. In Bogota, prevalence rate was 15.1 per 10 000 live births, whereas in Cali it was 17.29 per 10 000 live births. Family history of clubfoot within first-degree relatives was identified as a risk factor for clubfoot. Investigating risk factors for clubfoot holds significant importance in terms of preventing and reducing morbidity within this population. Helping to drive government and healthcare initiatives aimed at providing timely and effective treatment.

COL1A1 regulates the apoptosis of embryonic stem cells by mediating the PITX1/TBX4 signaling

PURPOSE

The purpose of this study is to explore the regulatory function of COL1A1 against the apoptosis of embryonic stem cells (ESCs) and the potential function in congenital talipes equinovarus (CTEV).

METHODS

Muscle tissues were collected from 20 children with CTEV and 20 children without CTEV, followed by detecting the expression of COL1A1 using the RT-PCR method. COL1A1 was knocked down in H1 and H9 human ESCs using the RNA interference technology, followed by determining the level of COL1A1, PITX1, TBX4, HOXD10, Fas, FasL, and Bax using the Western blotting assay.

RESULTS

COL1A1 was found markedly upregulated in muscle tissues of CTEV children. In H1 and H9 human ESCs, compared to the empty vector, COL1A1, PITX1, TBX4, HOXD10, Fas, FasL, and Bax were found notably downregulated after transfected with the siRNA targeting COL1A1.

CONCLUSION

COL1A1 induced the apoptosis of ESCs by mediating the PITX1/TBX4 signaling and might be a potential target for treating CTEV.

Prenatal diagnosis and genetic etiology analysis of talipes equinovarus by chromosomal microarray analysis

BACKGROUND

With the advancement of molecular technology, fetal talipes equinovarus (TE) is believed to be not only associated with chromosome aneuploidy, but also related to chromosomal microdeletion and microduplication. The study aimed to explore the molecular etiology of fetal TE and provide more information for the clinical screening and genetic counseling of TE by Chromosomal Microarray Analysis (CMA).

METHODS

This retrospectively study included 131 fetuses with TE identified by ultrasonography. Conventional karyotyping and SNP array analysis were performed for all the subjects. They were divided into isolated TE group (n = 55) and complex group (n = 76) according to structural anomalies.

RESULTS

Among the total of 131 fetuses, karyotype analysis found 12(9.2%) abnormal results, while SNP array found 27 (20.6%) cases. Trisomy 18 was detected most frequently among abnormal karyotypes. The detection rate of SNP array was significantly higher than that of traditional chromosome karyotype analysis (P < 0.05). SNP array detected 15 (11.5%) cases of submicroscopic abnormalities that karyotype analysis did not find. The most common CNV was the 22q11.2 microdeletion. For both analyses, the overall detection rates were significantly higher in the complex TE group than in the isolated TE group (karyotype: P < 0.05; SNP array: P < 0.05). The incremental yield of chromosomal abnormalities in fetuses with unilateral TE (22.0%) was higher than in fetuses with bilateral TE (19.8%), but this difference was not statistically significant (P > 0.05). Abnormal chromosomes were most frequently detected in fetuses with TE plus cardiovascular system abnormalities.

CONCLUSION

Fetal TE is related to chromosomal microdeletion or microduplication. Prenatal diagnosis is recommended for fetuses with TE, and CMA testing is preferred. CMA can improve the detection rate of chromosomal abnormalities associated with fetal TE, especially in pregnancies with complex TE.

Update from a cohort study for birth defects in Hunan Province, China, 2010-2020

To define the relationship between sex, residence, maternal age, and a broad range of birth defects by conducting a comprehensive cross-analysis based on up-to-date data. Data were obtained from the Birth Defects Surveillance System in Hunan Province, China, 2010-2020. Prevalences of birth defects (number of cases per 10,000 fetuses (births and deaths at 28 weeks of gestation and beyond)) with 95% confidence intervals (CI) were calculated by sex, residence, maternal age, year, and 23 specific defects. Cross-analysis of sex, residence, and maternal age was conducted, and crude odds ratios (ORs) were calculated to examine the association of each maternal characteristic with birth defects. A total of 1,619,376 fetuses and 30,596 birth defects were identified. The prevalence of birth defects was 188.94/10,000 (95% CI 186.82-191.05). Birth defects were more frequent in males than females (210.46 vs. 163.03/10,000, OR = 1.30, 95% CI 1.27-1.33), in urban areas than in rural areas (223.61 vs. 162.90/10,000, OR = 1.38, 95% CI 1.35-1.41), and in mothers ≥ 35 than mothers 25-29 (206.35 vs. 187.79/10,000, OR = 1.10, 95% CI 1.06-1.14). Cross-analysis showed that the prevalence of birth defects was higher in urban females than in rural males (194.53 vs. 182.25/10,000), the difference in prevalence between males and females was more significant for maternal age < 20 compared to other age groups (OR = 1.64, 95% CI 1.37-1.95), and the prevalence difference between urban and rural areas is more significant for maternal age 25-34 compared to other age groups (OR = 1.49, 95% CI 1.43-1.57). Cleft palates were more frequent in males, and nine specific defects were more frequent in females. Five specific defects were more frequent in rural areas, and eight were more frequent in urban areas. Compared to mothers 25-29, five specific defects were more frequent in mothers < 20, seven specific defects were more frequent in mothers 20-24, two specific defects were more frequent in mothers 30-34, and ten specific defects were more frequent in mothers ≥ 35. Our data indicate that sex, residence, and maternal age differences in the prevalences of birth defects and most specific defects are common. We have found some new epidemiological characteristics of birth defects using cross-analysis, such as residence is the determining factor for the prevalence of birth defects, the difference in prevalence between males and females was more significant for maternal age < 20 compared to other age groups, the prevalence difference between urban and rural areas is more significant for maternal age 25-34 compared to other age groups. And differences in the epidemiological characteristics of some specific defects from previous studies. Future studies should examine mechanisms. Our findings contributed to clinical counseling and advancing research on the risk factors for birth defects.

A 'Hub and Spoke' Shared Care initiative for CTEV Ponseti service

Aims

The Ponseti method is the gold standard treatment for congenital talipes equinovarus (CTEV), with the British Consensus Statement providing a benchmark for standard of care. Meeting these standards and providing expert care while maintaining geographical accessibility can pose a service delivery challenge. A novel 'Hub and Spoke' Shared Care model was initiated to deliver Ponseti treatment for CTEV, while addressing standard of care and resource allocation. The aim of this study was to assess feasibility and outcomes of the corrective phase of Ponseti service delivery using this model.

Methods

Patients with idiopathic CTEV were seen in their local hospitals ('Spokes') for initial diagnosis and casting, followed by referral to the tertiary hospital ('Hub') for tenotomy. Non-idiopathic CTEV was managed solely by the Hub. Primary and secondary outcomes were achieving primary correction, and complication rates resulting in early transfer to the Hub, respectively. Consecutive data were prospectively collected and compared between patients allocated to Hub or Spokes. Mann-Whitney U test, Wilcoxon signed-rank test, or chi-squared tests were used for analysis (alpha-priori = 0.05, two-tailed significance).

Results

Between 1 March 2020 and 31 March 2023, 92 patients (139 feet) were treated at the service (Hub 50%, n = 46; Spokes 50%, n = 46), of whom nine were non-idiopathic. All patients (n = 92), regardless of allocation, ultimately achieved primary correction, with idiopathic patients at the Hub requiring fewer casts than the Spokes (mean 4.0 (SD 1.4) vs 6.9 (SD 4.4); p < 0.001). Overall, 60.9% of Spokes' patients (n = 28/46) required transfer to the Hub due to complications (cast slips Hub n = 2; Spokes n = 17; p < 0.001). These patients ultimately achieved full correction at the Hub.

Conclusion

The Shared Care model was found to be feasible in terms of providing primary correction to all patients, with results comparable to other published services. Complication rates were higher at the Spokes, although these were correctable. Future research is needed to assess long-term outcomes, parents' satisfaction, and cost-effectiveness.

Neglected Clubfoot- a Community Health Challenge in Rural Odisha, India

Introduction

Neglected clubfoot deformities are very rigid & stiff that need surgical correction. Unlike countries like china, Uganda, and Malawi, no dedicated National program has been implemented for clubfoot management in India. The burden of disability from untreated or partly treated clubfoot is relatively high. With the existing issues, it has been observed that untreated clubfoot is a public health problem in most low and middle-income countries.

Objective

To conduct an observational analysis of the community approach to the correction of neglected clubfoot by corrective rehabilitation surgery camps.

Methods

The study included the retrospective data of all the neglected clubfoot children who had undergone clubfoot corrective surgery in 13 different remote districts of Odisha, held every year between February 2014 to October 2022 except during covid 19 pandemic period (2020 and 2021). A total of 993 clubfeet of 731 children were corrected through community approach-based corrective camp surgery. Follow-up was done for all the operated children with post-op plaster and orthosis till they returned back to the community.

Results

About 46.78% of study participants were within the age group of 5 years. Male presentation [454 males (62.10%)] was reportedly found 1.6 times higher than the female [277 females (37.89%)]. Most of them belonged to minor communities, socially and economically backward classes from various rural districts of eastern India. The Association of different socially backward categories of clubfoot children with the district they belonged to, was found significant statistically (p value < 0.001). When gender distribution was compared among the district where surgical camps were conducted, the association was statistically not significant (p value = 0.676).

Conclusion

Neglected clubfoot in rural areas can be managed by camp approach. The establishment of a robust standard operating procedure for the conduction of community-based surgical camps may be required to reduce the morbidity level in children with neglected clubfoot.

Trends in congenital clubfoot prevalence and co-occurring anomalies during 1994-2021 in Denmark: a nationwide register-based study

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.

The global birth prevalence of clubfoot: a systematic review and meta-analysis

Background

Estimates of the birth prevalence of clubfoot in low and middle income settings range from 0.5 to 2 per 1000 births. However, there is currently no estimate of global birth prevalence of clubfoot.

Methods

We conducted a systematic review of studies reporting the birth prevalence of clubfoot across all countries and regions worldwide in the last 10 years. Africa Wide Information, EMBASE, CINAHL, Global Health, LILACS and Medline databases were searched for relevant studies from January 1st 2012 to February 9th 2023. Pooled prevalence estimates were calculated using the inverse variance method, and a random effects model was applied to account for heterogeneity between studies. Quality appraisal was performed using a modified Newcastle-Ottawa Quality Assessment Scale for Cohort studies. This review was registered with PROSPERO, CRD42023398410.

Findings

The search generated 757 studies. Thirty-five studies from 36 countries and five WHO regions were included. The pooled prevalence of clubfoot was 1.18 per 1000 births (95% CI: 1.00-1.36) based on data from 44,818,965 births. The highest prevalence rates were observed in low- and middle-income countries, particularly in the South-East Asia Region (1.80, 95% CI: 1.32-2.28) and the Africa Region (1.31, 95% CI: 0.86-1.77). We estimate that 176,476 (95% CI: 126,126-227,010) children will be born with clubfoot globally each year.

Interpretation

This study provides a comprehensive estimate of the global prevalence of clubfoot and highlights the significant burden of this condition, particularly in low- and middle-income countries. The findings underscore the need for improving access to effective treatment and prevention strategies in resource-limited settings.

Funding

SR received funds from the Global Clubfoot Initiative and the Rhodes Trust.

Factors Related to Relapse of Congenital Talipes Equinovarus (CTEV) After the Ponseti Method

BACKGROUND

Congenital talipes equinovarus (CTEV) is one of the common congenital disorders in pediatric orthopedic practice that affects a large group of children.It is a combination of four parts of deformity that affect either a single foot or both feet. Our aim in this study is to estimate the prevalence and incidence of CTEV and to evaluate the risk factors that lead to relapse in some children to avoid relapse in future and complex surgical interventions, as well as to improve the final outcome.

MATERIALS AND METHODS

A retrospective cohort study for the cases of CTEV was conducted to estimate the prevalence of relapse in children with CTEV after management by the Ponseti method and to evaluate the risk factors that lead to recurrence.

RESULT

The study includes 103 patients with CTEV, and only 22 patients had relapse. The prevalence rate of relapsed cases was 20.4%, and the incidence was 42 per thousand. The average number of casts applied was 4.05 ± 1.37. The average severity of the deformity that was measured by the Pirani score was 4.97 ± 1.21. The most common atypical presentation of CTEV was associated with developmental dysplasia of the hip (DDH), followed by myelomeningocele (MMC).

CONCLUSION

The only significant factors in the study were the Pirani score and non-compliance of the brace with p < 0.05. There was not any significance in the correction of the deformity by Ponseti between idiopathic and non-idiopathic CTEV based on the number of casts and the Pirani score. The dynamic foot brace can be the solution for the high recurrence rate, yet more studies are needed in the future.

Congenital Talipes Equinovarus Management and Outcomes: The Experiences of Pediatric Tertiary Centers in Abha, Saudi Arabia

BACKGROUND

Congenital talipes equinovarus (CTEV), also known as clubfoot, describes a range of foot abnormalities usually present at birth (congenital) in which a baby's foot is twisted out of shape or position. In clubfoot, tendons are shorter than usual. Clubfoot is a fairly common birth defect and is usually an isolated problem for an otherwise healthy newborn.

AIM

This study aimed to investigate the experiences of pediatric tertiary centers in Abha, Saudi Arabia, regarding the management, frequency, treatment options, and outcomes of CTEV.

METHODS

A retrospective chart review of pediatric patients with clubfoot was conducted to evaluate the number of cases, treatment options, and outcomes at Abha Maternity and Children Hospital and Khamis Mushait Maternity and Children Hospital. Data were extracted independently using prestructured data extraction forms. The collected data included demographic and medical information, family history, clinico-epidemiological information, risk factors, management options, and complications of clubfoot.

RESULTS

The study included 89 children with CTEV from the target hospitals. Their ages ranged from 20 days to six years, with a mean age of 10.5 ± 14.5 months. Of these, 57 (64%) were male. CTEV was unilateral in 53 (59.5%) cases and bilateral in 36 (40.5%) cases. The majority of the cases had isolated CTEV. Nearly all cases had Ponseti casting with a tendo-Achilles tenotomy (TAT) surgical procedure. Patient follow-up ranged from one week to three years, with an average follow-up of 3.1 months. Only three (3.4%) cases experienced recurrence of deformity after management.

CONCLUSION

Ponseti casting with the tendo-Achilles tenotomy approach emerged as the most commonly employed management option, demonstrating a low rate of recurrence.

Exploring Bracing Adherence in Ponseti Treatment of Clubfoot: A Comparative Study of Factors and Outcomes in Uganda

The Ponseti method of clubfoot treatment involves two phases: initial correction, usually including tenotomy; and bracing, to maintain correction and prevent relapse. Bracing should last up to four years, but in Uganda, approximately 21% of patients drop from clinical oversight within the first two years of using the brace. Our study compared 97 adherent and 66 non-adherent cases to assess the influential factors and effects on functional outcomes. We analyzed qualitative and quantitative data from clinical records, in-person caregiver interviews, and assessments of foot correction and functionality. Children who underwent tenotomy had 74% higher odds of adherence to bracing compared to those who did not undergo tenotomy. Conversely, children from rural households whose caregivers reported longer travel times to the clinic were more likely to be non-adherent to bracing (AOR 1.60 (95% CI: 1.11-2.30)) compared to those without these factors. Adhering to bracing for a minimum of two years was associated with improved outcomes, as non-adherent patients experienced 2.6 times the odds of deformity recurrence compared to adherent patients. Respondents reported transportation/cost issues, family disruptions, and lack of understanding about the treatment method or importance of bracing. These findings highlight the need to address barriers to adherence, including reducing travel/waiting time, providing ongoing education for caregivers on bracing protocol, and additional support targeting transportation barriers and household complexities.

The burden, prevention and care of infants and children with congenital anomalies in sub-Saharan Africa: A scoping review

The aim of this scoping review was to determine the scope, objectives and methodology of contemporary published research on congenital anomalies (CAs) in sub-Saharan Africa (SSA), to inform activities of the newly established sub-Saharan African Congenital Anomaly Network (sSCAN). MEDLINE was searched for CA-related articles published between January 2016 and June 2021. Articles were classified into four main areas (public health burden, surveillance, prevention, care) and their objectives and methodologies summarized. Of the 532 articles identified, 255 were included. The articles originated from 22 of the 49 SSA countries, with four countries contributing 60% of the articles: Nigeria (22.0%), Ethiopia (14.1%), Uganda (11.7%) and South Africa (11.7%). Only 5.5% of studies involved multiple countries within the region. Most articles included CA as their primary focus (85%), investigated a single CA (88%), focused on CA burden (56.9%) and care (54.1%), with less coverage of surveillance (3.5%) and prevention (13.3%). The most common study designs were case studies/case series (26.6%), followed by cross-sectional surveys (17.6%), retrospective record reviews (17.3%), and cohort studies (17.2%). Studies were mainly derived from single hospitals (60.4%), with only 9% being population-based studies. Most data were obtained from retrospective review of clinical records (56.1%) or via caregiver interviews (34.9%). Few papers included stillbirths (7.5%), prenatally diagnosed CAs (3.5%) or terminations of pregnancy for CA (2.4%).This first-of-a-kind-scoping review on CA in SSA demonstrated an increasing level of awareness and recognition among researchers in SSA of the contribution of CAs to under-5 mortality and morbidity in the region. The review also highlighted the need to address diagnosis, prevention, surveillance and care to meet Sustainable Development Goals 3.2 and 3.8. The SSA sub-region faces unique challenges, including fragmentation of efforts that we hope to surmount through sSCAN via a multidisciplinary and multi-stakeholder approach.

An Insight on Current Clubfoot Management: A Reported Data From Lebanon

BACKGROUND/AIM

Clubfoot, which has been reported in the literature since the time of Hippocrates in 400 BC, is regarded as one of the most difficult congenital orthopedic anomalies, with a high relapse incidence of 16.87 infants per 10,000 births. The Lebanese region holds limited data concerning the evolution of clubfoot management. Herein, we aim to present novel findings in the treatment of clubfoot without surgical intervention.

MATERIALS AND METHODS

This single-center, cross-sectional research included 300 patients with virgin idiopathic clubfoot treated at our facility from 2015 to 2020. The Pirani and DiMeglio Scores were used to determine the severity of the illness prior to treatment, and the DiMeglio Score was used to determine the severity of the disease after treatment. For data analysis, the Statistical Package for Social Sciences (SPSS, IBM-Version 26; IBM Corp., Armonk, NY) was used and results with p-value < 0.05 were considered statistically significant.

RESULTS

Our study included 300 patients, with 188 boys (62.7%) and 112 girls (37.3%). The mean age of the patients' onset was 32 days. We recorded an average initial Pirani score of 4.27 ± 0.65 and an average initial DiMeglio score of 11.58 ± 2.56 (62 out of 300) while the average final DiMeglio score was 2.17 ± 1.82. The mean number of casts was 5 ± 0.8, with a minimum of four and a maximum of six casts. The prevalence of relapse was 20.7%.

CONCLUSIONS

Clubfoot remains a challenging deformity with a high rate of treatment failure and recurrence. While the superiority of Ponseti's technique in terms of success rate could not be disputed, tailored therapy based on the patient's socioeconomic status is considered critical for compliance and treatment success.

Functional Implications of Flat-Topped Talus Following Treatment of Idiopathic Clubfoot Deformity

BACKGROUND

Though flatness of the talar dome (TD) is a potential consequence of operative and nonoperative clubfoot management, the functional impact of this deformity is not well understood. This study analyzes the relationship between TD morphology and ankle function at skeletal maturity in patients treated for idiopathic clubfoot during infancy.

METHODS

33 skeletally mature patients (average age 17.9 years) with 48 idiopathic clubfeet were identified. Weightbearing radiographs, gait analysis, and patient-reported outcomes using the Pediatric Orthopaedic Data Collection Instrument (PODCI) were obtained. Radius of curvature (ROC) of the TD and tibial plafond were measured along with other parameters of talar and calcaneal morphology. All measurements were correlated to PODCI scores and gait analysis data.

RESULTS

Patients demonstrated marked variability in ROC of the TD (mean 30.8 mm, SD 13.6 mm), TD radius to talar length (R/L) ratio (mean 0.56, SD 0.28), opening angle of the TD (alpha angle) (mean 89.6°, SD 28.4°), and tibiotalar incongruity index (mean 0.18, SD 0.16). Increased tibiotalar incongruity index correlated with decreased maximum plantar flexion (r = ‒0.325, P = .02). A less acute alpha angle of the talar dome correlated with increased maximum ankle power generation (r = 0.321, P = .03) as did increased length of the talar neck (r = 0.358, P = .013). Increased tibiotalar incongruity index correlated negatively with PODCI global function domain scores (r = ‒0.490, P = .04; r = ‒0.381, P = .03, respectively), whereas length of the talar body correlated with higher global function scores (r = 0.376, P = .03) and lower pain scores (r = 0.350, P = .046).

CONCLUSION

At skeletal maturity, flattening of the talar dome and tibiotalar incongruity on plain radiographs correlate modestly with gait changes, whereas tibiotalar incongruity and length of the talar body, not flatness of the talar dome, correlate with decreased patient-reported outcome scores.

Use of Ankle Dorsiflexion and the Dimeglio and Pirani Scores in Predicting Relapse of Clubfoot Treated With the Ponseti Method

Although Dimeglio and Pirani scores are frequently employed to rate the severities of clubfoot and to evaluate treatment outcomes, it is unclear if these scores predict relapse after treatment. Ankle dorsiflexion has been suggested in recent years to be a promising predictor of relapse. The aim of this study was to investigate ankle dorsiflexion and Dimeglio and Pirani scores in predicting the relapse of clubfoot after treatment with the Ponseti method. We included patients with clubfoot previously treated by the Ponseti method, and retrospectively analyzed their initial ankle dorsiflexion, Pirani and Dimeglio scores, number of castings, and the occurrence of relapse. We analyzed 218 feet of 176 infants with clubfoot who showed an incidence of relapse of 17.0% (30/176). The mean initial Pirani and Dimeglio scores of the feet showing recurrence were significantly higher than individuals with non-recurrence (p < .001 each). We observed a robust association between Pirani and Dimeglio scores and the recurrence of clubfoot at the last follow-up (γ = 0.53, p = .001). In contrast, ankle dorsiflexion was negatively correlated with recurrence of clubfoot (γ = -0.21, p = .001). Dimeglio scores significantly predicted the recurrence of clubfoot (p = .014). Receiver operating characteristic curve analysis exhibited slightly better performance regarding the Dimeglio score relative to the Pirani score and ankle dorsiflexion in predicting recurrence. Ankle dorsiflexion and Pirani and Dimeglio scores were related to recurrence in patients with clubfoot. However, the Dimeglio score reflected superior accuracy in predicting the prognosis of clubfoot treated with the Ponseti method.

Clubfoot from past to the present: A bibliometric analysis with global productivity and research trends

Clubfoot, a common congenital abnormality, affects the lower extremities; however, the literature search revealed no bibliometric research on this subject. Thus, we aimed to holistically analyze scientific articles and reveal global productivity and trend issues. This study statistically analyzed 1417 published articles on clubfoot (1980-2021) from the Web of Science database. Bibliometric network visualization maps were created to reveal trend topics, citation analysis, and cross-country collaborations. The analysis was conducted using Spearman correlation analysis. An exponential smoothing estimator was used to predict article productivity. The United States of America (433, 30.5%), the United Kingdom (166, 11.7%), and India (107, 7.5%) are the top 3 countries contributing to the literature. The Journal of Pediatric Orthopedics (220 articles), the Journal of Pediatric Orthopedics-Part B (147 articles), and Clinical Orthopedics and Related Research (69 articles) are the top 3 most productive journals. Dobbs MB (34 articles) is the most active author, and Shriners Hospital Children (44 articles) is the most active institution. Bibliometric analysis revealed that recently studied trend topics included Pirani score, Dimeglio score, Ponseti method, Ponseti casting, tenotomy, recurrence, neglected, tendon transfer, bracing, gait, risk factors, pedobarography, complex clubfoot, and polymorphism. The most studied subjects included Ponseti technique, treatment/casting, recurrent/relapsed clubfoot, Pirani score, pediatrics/children, foot deformities, surgery, ultrasound, Achilles tendon/tenotomy, gait analysis, casting, outcomes, neglected clubfoot, and tenotomy. Research leadership was determined in the western and European countries and Canada in studies and scientific collaborations on clubfoot; its impact was remarkable in India, China, and Turkey.

Gait Analysis Characteristics in Relapsed Clubfoot

BACKGROUND

Relapse rates of clubfoot deformity after initial correction range between 19% and 68% regardless of treatment approach. Most studies focus on relapse before age 4. Little research has focused on late clubfoot relapse. The purpose of this study was to compare the gait characteristics of children with late clubfoot relapse (age ≥5 y) following treatment with the Ponseti method only compared with intra-articular and extra-articular surgeries.

METHODS

A retrospective review was conducted of all patients with idiopathic clubfoot ≥5 years old who underwent computerized gait analysis for clubfoot relapse between 2001 and 2021. Joint range of motion, muscle strength, gait kinematics, and kinetics were compared among 3 groups based on prior clubfoot treatment: (1) Ponseti casting, (2) Extra-articular (EA) surgery, and (3) Intra-articular (IA) surgery.

RESULTS

Sixty-eight subjects (107 feet) were included (39 bilateral). Thirty-one percent of feet had been treated with Ponseti casting alone; 57% had IA surgery, and 12% had EA surgery. The average age when presenting with late relapse was 8.2 years, 9.0 years and 10.7 years for the Ponseti, and IA and EA groups, respectively. The IA group had greater passive dorsiflexion than the other 2 groups (P<0.002), greater inversion weakness than the other 2 groups (P<0.0001), greater dorsiflexion during the stance phase of gait compared with the Ponseti group (P=0.001), and lower maximum power production at push-off compared with the other 2 groups (P=0.009).

CONCLUSION

Late relapse can occur after all types of clubfoot correction. Consistent with existing literature, patients who have undergone posteromedial release surgery have significantly greater plantarflexor weakness resulting in poorer plantarflexor moment and power production during gait.

Common Errors in the Management of Idiopathic Clubfeet Using the Ponseti Method: A Review of the Literature

Congenital talipes equinovarus is one of the most prevalent birth defects, affecting approximately 0.6 to 1.5 children per 1000 live births. Currently, the Ponseti method is the gold-standard treatment for idiopathic clubfeet, with good results reported globally. This literature review focuses on common errors encountered during different stages of the management of idiopathic clubfeet, namely diagnosis, manipulation, serial casting, Achilles tenotomy, and bracing. The purpose is to update clinicians and provide broad guidelines that can be followed to avoid and manage these errors to optimize short- and long-term outcomes of treatment of idiopathic clubfeet using the Ponseti method. A literature search was performed using the following keywords: "Idiopathic Clubfoot" (All Fields) AND "Management" OR "Outcomes" (All Fields). Databases searched included PubMed, EMBASE, Cochrane Library, Google Scholar, and SCOPUS (age range: 0-12 months). A full-text review of these articles was then performed looking for "complications" or "errors" reported during the treatment process. A total of 61 articles were included in the final review: 28 from PubMed, 8 from EMBASE, 17 from Google Scholar, 2 from Cochrane Library, and 6 from SCOPUS. We then grouped the errors encountered during the treatment process under the different stages of the treatment protocol (diagnosis, manipulation and casting, tenotomy, and bracing) to facilitate discussion and highlight solutions. While the Ponseti method is currently the gold standard in clubfoot treatment, its precise and intensive nature can present clinicians, health care providers, and patients with potential problems if proper diligence and attention to detail is lacking. The purpose of this paper is to highlight common mistakes made throughout the Ponseti treatment protocol from diagnosis to bracing to optimize care for these patients.

Clubfoot: an overview and the latest UK guidelines

Clubfoot is one of the most common congenital anomalies, affecting every 1 of 1000 live births in the UK. Historically, clubfeet have been managed with a variety of conservative and operative techniques. Over the last two decades, the Ponseti serial casting method has become the gold standard of treatment. In July 2021, the British Society of Children's Orthopaedic Surgery (Gelfer et al, 2022) published a consensus statement that outlines the optimal management for clubfoot. This article provides an overview of clubfoot and a summary of the latest management guidelines.

Community Awareness of Congenital Talipes Equinovarus (Clubfoot) in Makkah Region, Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Congenital talipes equinovarus (CTEV) or clubfoot is known as a deformity characterized by excessively turned-in feet and high medial longitudinal arches. It is one of the most common musculoskeletal abnormalities. It is estimated that approximately 20% of CTEV cases are caused by another congenital disease or syndromic condition.

OBJECTIVES

The aim of this study was to assess the knowledge about CTEV among the general population in the Makkah region of the kingdom.  Methods: This study was a community-based cross-sectional descriptive study carried on by an online questionnaire, previously validated in published studies, among residents in the Makkah region of Saudi Arabia who successfully fulfilled the inclusion and exclusion criteria.  Results: Out of the total number of respondents (n=1,987), gender was found to be significantly associated with awareness about CTEV (p-value=0.007) as females tend to have higher awareness levels than males. Having a child with CTEV was found to be significantly associated with awareness level (p-value˂0.001). In addition, university and secondary levels of education are more aware of CTEV than other levels of education (p-value=0.023).

CONCLUSION

According to the results, the lack of awareness campaigns may contribute to the low public awareness of CTEV. It is recommended that social media platforms and public campaigns be utilized to increase awareness of CTEV in key locations such as malls. These initiatives may motivate people to seek treatment for their disease as early as possible. In addition, early management of CTEV is less invasive and leads to better patient outcomes when followed up regularly.

Factors Causing Dropout From Treatment During the Ponseti Method of Clubfoot Management: The Caregivers' Perspective

A retrospective comparative study was conducted, aiming to identify factors associated with dropout from clubfoot treatment by Ponseti method in low- and middle-income countries. A prospectively gathered database of patients who received treatment at a high-volume urban clubfoot clinic over 6 years was queried for dropouts. A "dropout" was identified as any child that had not had a visit within 3 weeks of casting, 4 weeks of tenotomy or 6 months of brace follow-up. The second part of the study was a telephonic interview with caregivers of the identified dropouts to ascertain their reasons for discontinuing treatment. Of the 965 patients treated during the study period, there were 155 (16.06%) dropouts-137 (88.38%) during bracing phase and 18 (11.62%) during casting phase. Age at presentation was significantly higher among the dropouts as compared to those who did not dropout (median 9.5 and 7 months for casting and bracing dropouts respectively versus 3.5 months for regular follow-ups, p < .001). No significant correlation was found between patient dropout and sex (p = .061), or laterality (p = .071). Thirty-seven caregivers (23.8%) could be contacted telephonically; including 6 casting and 31 bracing dropouts. The most commonly cited reason for dropout from treatment was lack of family support (75.7%), followed by distance to the clinic (59.5%) and unavailability of transport (54.1%). Sixteen caregivers (43.2%) dropped out on account of migration to another town/state. Maintenance of a meticulous registry with regular update of caregivers' contact details, and interventions to mitigate the identified hurdles can help in reducing treatment dropouts.

Novel report on congenital talipes equinovarus (CTEV) following olanzapine exposure during pregnancy: case report and short review

Olanzapine is widely used during pregnancy to manage mood and psychotic disorders with overall beneficial effects. There have been past reports of olanzapine exposure during early pregnancy and clubfoot in two newborns from India and Israel. We report a woman in Nepal diagnosed with schizophrenia and treated with olanzapine throughout the pregnancy delivering a baby boy with congenital talipes equinovarus deformity. Like in many other low-income settings, pregnancy was unplanned, and pre-conception counselling was not done. Research in mice has revealed the negative effects of olanzapine on bone development. Further reports would strengthen this potential association between exposure to olanzapine in the first trimester and the occurrence of clubfoot in the baby.

Incidence of Congenital Clubfoot: Preliminary Data from Italian CeDAP Registry

(1) Background: We find the incidence of clubfoot in Italy from "Certificate of Delivery Care Registry (CeDAP)", a database of the Italian Ministry of Health, the most comprehensive public data available for this purpose. (2) Methods: The CeDAP registry is a web system that provides epidemiological and sociodemographic information about newborns. It started on 1 January 2002, following the ministerial Decree no. 349 of 16 July 2001. The certificate is structured into six sections; each collects specific information referring to the birthplace, parents, pregnancy, childbirth, newborn, and the possible presence of congenital malformations or the causes of neonatal mortality. The midwife or the doctor draws up the certificate no later than ten days after birth. Each region transmits the data every six months to the Ministry of Health. The period between 2013 and 2017 has been selected for the study, with every Italian region's data. We conducted a retrospective descriptive study. (3) Results: The overall rate in northern Italy is 1.09 (with some exceptions described), but we think it is essential to reevaluate this number again, given more accurate data collections by every Italian hospital. (4) Conclusions: This study intends to build a framework for future epidemiologic studies about clubfoot in Italy.

Magnetic resonance imaging of severe idiopathic club foot treated with one-week accelerated Ponseti (OWAP) technique

PURPOSE

This study aims to evaluate changes in tarsal bones relationship after the use of one week accelerated Ponseti method in the treatment of severe idiopathic clubfoot using MRI. We hypothesize that one-week accelerated Ponseti is at least as effective as standard techniques in achieving the desirable MRI parameters.

METHODS

This is a prospective study of 8 children with severe idiopathic clubfeet (Pirani 6) (4 unilateral and 4 bilateral) treated before the age of three months with one-week accelerated Ponseti technique, as described in a former study with minimum 2-year follow-up. The 8 corrected feet were compared with the 4 unilateral normal feet at clinical and radiological levels using a Pirani scoring system and an MRI, respectively.

RESULTS

Clinical results showed that Pirani score was 1.1 in the last follow up in comparison to Pirani 6 pretreatment (p < 0.05). MRI results indicated that the malleocalcaneal angle, axial malleocalcaneal index, coronal tibiocalcaneal angle, sagittal talocalcaneal angle, and talar head neck calcaneal rotation showed statistical difference between the two groups (p < 0.05). Sagittal malleocalcaneal index, sagittal tibiocalcaneal angle, talar head neck rotation related to talar body, and posterior calcaneal rotation showed no statistical difference between normal feet and clubfeet after correction (p value >0.05).

CONCLUSION

One-week accelerated Ponseti technique showed to be as effective and safe as other treatment methods through clinical and MRI follow up data. MRI role was to confirm the efficiency of this innovative accelerated technique, but not used as a routine follow up.

Are early antero-posterior and lateral radiographs predictive of clubfoot relapse requiring surgical intervention in children treated by Ponseti method?

Purpose

To investigate the value of antero-posterior and lateral radiographs in predicting clubfoot relapse after treatment with the Ponseti method.

Methods

This was a retrospective review of 104 children (157 feet) younger than 3 months of age with idiopathic clubfoot treated using the Ponseti method at our institution between January 2007 and December 2014. All patients underwent Achilles tenotomy and were divided into two groups according to the need for further surgery to correct the deformity: relapsed group (24 patients; 36 feet) and non-relapsed group (80 patients; 121 feet). All antero-posterior and lateral foot radiographs were performed less than 3 months after Achilles tenotomy. The talo-calcaneal (TC-AP) and talus-first metatarsal (TM-AP) angles were measured in the antero-posterior view, while the tibio-calcaneal (TIC-L), talus-first metatarsal (TM-L), and talo-calcaneal (TC-L) angles were measured in the lateral view. The multi-factor logistic regression model of the stepwise selection method was used to predict the relapse of clubfoot deformity from the potential predictive values.

Results

The mean age at initial plain radiography examination was 99.45 ± 21.54 days. Differences in TC-AP, TM-AP, TC-L, and TIC-L between the two groups were statistically significant. However, only TM-AP and TIC-L were included in the "risk of relapse" formula using the multi-factor logistic stepwise selection method.

Conclusion

Early antero-posterior and lateral radiographs in children younger than 3 months of age at initial Ponseti treatment have positive predictive value for relapse. Reduced TM-AP angle and increased TIC-L were associated with an increased risk of relapse.

Impact of COVID-19 pandemic on clubfoot program at tertiary care institute

PURPOSE

The COVID-19 pandemic had serious impact on health care sector. During reprioritisation of the services, elective and non-emergency procedures were suspended, with gradual resumption of services after lockdown was over. In this study we assessed the impact of pandemic on our clubfoot program at a tertiary care institute. Also, we discussed the future challenges and strategies to re-start our clubfoot program.

METHODS

Data was collected retrospectively regarding registrations, demography and procedures done at our clubfoot centre. Study period was 25 March to 31 December 2020 and it was compared with same duration from previous years 2019 and 2018. After the data analysis, the findings were discussed on departmental committee meeting, future challenges were considered and strategies were charted out for re-establishing the clubfoot program at our Institute.

RESULTS

When compared to previous year, we noted 46% decline in paediatric outpatient registrations and 60% decline in new clubfoot registrations at our centre. The clubfoot follow-up visits reduced by 30% in the pandemic year 2020. 80% of clubfoot registrations were local residents during pandemic year, which was 54%, 58% in year 2019 and 2018 respectively. The percentage of neglected cases remained stable, however, share of relapse cases increased during pandemic year. There was 80% decline in number of tenotomies and 90% decline in other clubfoot surgeries performed during pandemic year 2020 compared to year 2019.

CONCLUSION

COVID-19 pandemic had definite disruptive impact on our clubfoot program. With decreased new registrations, follow-up visits and increased relapses, we anticipate a significant increase in clubfoot cases in need of casting & treatment. To deal with pent-up demand and an anticipated wave of relapse and neglected clubfoot cases, we have proposed strategies to re-establish clubfoot program in post-pandemic new-normal. We hope these will prepare us for any adversaries we face.

The outcomes of idiopathic congenital talipes equinovarus : a core outcome set for research and treatment

Aims

To identify the minimum set of outcomes that should be collected in clinical practice and reported in research related to the care of children with idiopathic congenital talipes equinovarus (CTEV).

Methods

A list of outcome measurement tools (OMTs) was obtained from the literature through a systematic review. Further outcomes were collected from patients and families through a questionnaire and interview process. The combined list, as well as the appropriate follow-up timepoint, was rated for importance in a two-round Delphi process that included an international group of orthopaedic surgeons, physiotherapists, nurse practitioners, patients, and families. Outcomes that reached no consensus during the Delphi process were further discussed and scored for inclusion/exclusion in a final consensus meeting involving international stakeholder representatives of practitioners, families, and patient charities.

Results

In total, 39 OMTs were included from the systematic review. Two additional OMTs were identified from the interviews and questionnaires, and four were added after round one Delphi. Overall, 22 OMTs reached ‘consensus in’ during the Delphi and two reached ‘consensus out’; 21 OMTs reached ‘no consensus’ and were included in the final consensus meeting. In all, 21 participants attended the consensus meeting, including a wide diversity of clubfoot practitioners, parent/patient representative, and an independent chair. A total of 21 outcomes were discussed and voted upon; six were voted ‘in’ and 15 were voted ‘out’. The final COS document includes nine OMTs and two existing outcome scores with a total of 31 outcome parameters to be collected after a minimum follow-up of five years. It incorporates static and dynamic clinical findings, patient-reported outcome measures, and a definition of CTEV relapse.

Conclusion

We have defined a minimum set of outcomes to draw comparisons between centres and studies in the treatment of CTEV. With the use of these outcomes, we hope to allow more meaningful research and a better clinical management of CTEV.

Regulation of COL1A2, AKT3 genes, and related signaling pathway in the pathology of congenital talipes equinovarus

Congenital talipes equinovarus (CTEV) is one of the most common congenital limb defects in children, which is a multifactorial and complex disease that associates with many unknown genetic, social-demographic, and environmental risk factors. Emerging evidence proved that gene expression or mutation might play an important role in the occurrence and development of CTEV. However, the underlying reasons and involved mechanisms are still not clear. Herein, to probe the potential genes and related signaling pathways involved in CTEV, we first identified the differentially expressed genes (DEGs) by mRNA sequencing in pediatric patients with CTEV compared with normal children. The gene of COL1A2 was upregulated, and AKT3 was downregulated at the transcriptional level. Western blot and quantitative polymerase chain reaction (qRT-PCR) results also showed that the expression of COL1A2 in CTEV was enhanced, and the AKT3 was decreased. Furthermore, the COL1A2 Knock-in (+COL1A2) and AKT3 Knock-out (-AKT3) transgenic mice were used to verify the effects of these two genes in the CTEV, and the results of which showed that both COL1A2 and AKT3 were closely related to the CTEV. We also investigated the effect of the PI3K-AKT3 signaling pathway in CTEV by measuring the relative expression of several key genes using Western blot and qRT-PCR. In line with the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis data, the PI3K-AKT3 signaling pathway might play a potentially important role in the regulation of pathological changes of CTEV. This study will provide new ideas for the mechanism investigation and prenatal diagnosis of CTEV.

Epidemiology of clubfoot in Sweden from 2016 to 2019: A national register study

Background

This study aimed to estimate the birth prevalence of children born with isolated or non-isolated clubfoot in Sweden using a national clubfoot register. Secondarily we aimed to describe the clubfoot population with respect to sex, laterality, severity of deformity, comorbidity and geographic location.

Methods

A national register, the Swedish Pediatric Orthopedic Quality register, was used to extract data on newborn children with clubfoot. To calculate the birth prevalence of children with isolated or non-isolated clubfoot between 1^st of January 2016 and 31^st of December 2019, we used official reports of the total number of Swedish live births from the Swedish Board of Statistics. The Pirani score and predefined signs of atypical clubfoot were used to classify clubfoot severity at birth.

Results

In total 612 children with clubfoot were identified. Of these, 564 were children with isolated clubfoot, generating a birth prevalence of 1.24/1000 live births (95% confidence interval 1.15–1.35). About 8% were children with non-isolated clubfoot, increasing the birth prevalence to 1.35/1000 live births (95% confidence interval 1.25–1.46). Of the children with isolated clubfoot, 74% were boys and 47% had bilateral involvement. The children with non-isolated clubfoot had more severe foot deformities at birth and a greater proportion of clubfeet with atypical signs compared with children with isolated clubfoot.

Conclusion

We have established the birth prevalence of children born with isolated or non-isolated clubfoot in Sweden based on data from a national register. Moreover, we have estimated the number of children born with atypical clubfeet in instances of both isolated and non-isolated clubfoot. These numbers may serve as a baseline for expected birth prevalence when planning clubfoot treatment and when evaluating time trends of children born with clubfoot.

Prenatal Diagnosis of Clubfoot: Where Are We Now? Systematic Review and Meta-Analysis

The primary methods for prenatal diagnosis of Clubfoot are ultrasound (US) and magnetic resonance imaging (MRI). An ultrasound is performed between the 1st trimester and the 28th week of pregnancy and it is reported to be used as a diagnostic method alone or in combination with MRI. So far, an international consensus on the most effective screening method has not been reached. This systematic review and meta-analysis were performed to establish the most effective and reliable exam for prenatal diagnosis of Clubfoot. The literature search was conducted using a PIOS-approach from May 2021 to June 2021. Studies reporting cases of prenatal diagnosis of Clubfoot made through US and MRI conducted from January 2010 to June 2021 were included in the study and reviewed by 2 authors. The 23 selected studies included 2318 patients. A total of 11 of the studies included details on the accuracy, while the rest were used to obtain information about the primary methodology utilized. In all the selected studies, US was used as the primary diagnostic instrument. Thirteen of the studies used the US exclusively, while three used MRI in addition to US and seven performed karyotyping after US diagnosis. The US has been shown to be the instrument of choice for the prenatal diagnosis of Clubfoot. International guidelines for an ultrasonography classification of congenital clubfoot are required to reduce the inter-variability accuracy of this procedure.

Increased Collagen Crosslinking in Stiff Clubfoot Tissue: Implications for the Improvement of Therapeutic Strategies

Congenital clubfoot is a complex musculoskeletal deformity, in which a stiff, contracted tissue forms in the medial part of the foot. Fibrotic changes are associated with increased collagen deposition and lysyl oxidase (LOX)-mediated crosslinking, which impair collagen degradation and increase the tissue stiffness. First, we studied collagen deposition, as well as the expression of collagen and the amount of pyridinoline and deoxypyridinoline crosslinks in the tissue of relapsed clubfoot by immunohistochemistry, real-time PCR, and enzyme-linked immunosorbent assay (ELISA). We then isolated fibroblast-like cells from the contracted tissue to study the potential inhibition of these processes in vitro. We assessed the effects of a LOX inhibitor, β-aminopropionitrile (BAPN), on the cells by a hydroxyproline assay, ELISA, and Second Harmonic Generation imaging. We also evaluated the cell-mediated contraction of extracellular matrix in 3D cell-populated collagen gels. For the first time, we have confirmed significantly increased crosslinking and excessive collagen type I deposition in the clubfoot-contracted tissue. We successfully reduced these processes in vitro in a dose-dependent manner with 10–40 µg/mL of BAPN, and we observed an increasing trend in the inhibition of the cell-mediated contraction of collagen gels. The in vitro inhibitory effects indicate that BAPN has good potential for the treatment of relapsed and resistant clubfeet.

Attaining a British consensus statement on managing idiopathic congenital talipes equinovarus (CTEV) through a Delphi process: a study protocol

INTRODUCTION

Idiopathic congenital talipes equinovarus (CTEV) is the most common congenital limb deformity. Non-operative intervention using the Ponseti method has shown to be superior to soft tissue release and has become the gold standard for first-line treatment. However, numerous deviations from the Ponseti protocol are still reported following incomplete correction or deformity relapse. Significant variation in treatment protocols and management is evident in the literature. Reducing geographical treatment variation has been identified as one of The James Lind Alliance priorities in children's orthopaedics. For this reason, the British Society of Children's Orthopaedic Surgery (BSCOS) commissioned a consensus document to form a benchmark for practitioners and ensure consistent high quality care for children with CTEV.

METHODS AND ANALYSIS

The consensus will follow an established Delphi approach aiming at gaining an agreement on the items to be included in the consensus statement for the management of primary idiopathic CTEV up to walking age. The process will include the following steps: (1) establishing a steering group, (2) steering group meetings, (3) a two-round Delphi survey aimed at BSCOS members, (4) final consensus meeting and (5) dissemination of the consensus statement. Degree of agreement for each item will be predetermined. Descriptive statistics will be used for analysis of the Delphi survey results.

ETHICS AND DISSEMINATION

No patient involvement is required for this project. Informed consent will be assumed from participants taking part in the Delphi survey. Study findings will be published in an open access journal and presented at relevant national and international conferences. Charities and associations will be engaged to promote awareness of the consensus statement.

Clubfoot management in the Middle East: a survey-based review

Clubfoot is the most frequent congenital deformity involving the foot. Little is known about the management of this disease in the Middle East as sparse data is available in the literature. Through the last 5 decades, congenital clubfoot management in the Middle East went from manipulation through Kite’s technique in the late seventies, to early primary surgical intervention in the late eighties and early nineties of the previous century, and then back to manipulation with Ponseti’s technique and the French functional technique in the late nineties, with the latter falling out of favor with time. This is comparable to the evolution of management witnessed in the United States and in Europe, with 10 to 15 years of delay. The delay is getting shorter with time due to the easier access to published scientific data and the increasing number of fellows from Middle East travelling to referral centers in Europe and the USA. A survey was performed among pediatric orthopedic surgeons in the Middle East to assess their approach to clubfoot management. This is the first survey of its kind in the region. It showed a wide adoption (97.1%) of the Ponseti’s technique with serial manipulation and casting, Achilles tenotomy followed by abduction bracing. Divergent practices were found concerning the upper age limit for Ponseti treatment and the setting of the Achilles tenotomy. Nevertheless, these subjects are still a matter of debate in the literature and international conferences. All in all, pediatric orthopedic surgeons in the Middle East are offering their patients the gold standard of care. However, lot of work is to be done in raising awareness for this disease in the community, and among our colleagues as prenatal screening for clubfoot in the Middle East is practically nonexistent.

Congenital Talipes Equinovarus: Results of Treatment and Are We Bracing Effectively?

The aim of this retrospective study was to assess our management of Congenial Talipes Equinovarus (CTEV) in relation to national standards published by the British Society for Children's Orthopaedic Surgery (BSCOS). A secondary aim was to evaluate if a more tailored bracing regime than advocated in the traditional Ponseti technique, would be appropriate for some cases of CTEV. One hundred and thirty-three feet in 96 patients were treated between June 2006 and January 2016. All patients were clinically assessed prospectively by the senior author at initial presentation using the Harrold & Walker classification system. A combination of the senior author's database, Elogbook and trust IT systems were used for data collection. The results of Ponseti surgical procedures such as tendoachilles release and tibialis transfer fell within the BSCOS guidelines. The rate of radical subtalar surgical release was higher than advocated (12.3%) which was partly due to the number of primary syndromal patients in the series. There was a significantly lower mean time spent in bracing of 14.3 months (95% confidence interval 14.8-19.3) compared to recommended national guidelines. There was a clinically significant difference in the lower relapse rate of female patients compared to male patients and also a higher propensity of surgical intervention in male patients. In addition, there was a statistically significant difference in both time spent in bracing, between H&W classifications and between patients who had bracing removed pre walking age or post walking age. This potentially demonstrates a more tailored bracing regime may be possible when applied to less severely affected feet and the condition may be more benign in female cases.

What is the optimal treatment for equinus deformity in walking-age children with clubfoot? A systematic review

Equinus contracture is the most common deformity at clubfoot relapse and causes pain and functional limitation. It presents a challenge to the orthopaedic surgeon throughout childhood.A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies included were: (i) original articles, (ii) investigating management of relapsed idiopathic clubfoot, (iii) with at least a partial study population of primarily equinus deformity, and (iv) a paediatric study population of independent walking age.Nine studies were included with a total of 163 patients (207 feet). Studies presented five management paradigms: gastrocnemius-soleus complex release, extensive posterior soft tissue and joint release, anterior distal tibial hemi-epiphysiodesis, distal tibial osteotomy, and circular frame distraction.All approaches reported success in at least one of our selected outcome domains: plantigrade status, range of motion, clinical outcome scores, functional status, radiographic outcomes, patient-reported outcomes, and complications. Younger children tend to be managed with soft tissue release while older children tend to require more extensive bone/joint procedures. Relapse in surgically treated feet is harder to treat.Comparison across treatment approaches is limited by the small size and low evidence level of the literature, as well as a lack of consistent outcome reporting. It is therefore not possible to recommend any one treatment option in any age group.This review highlights the need for a validated core outcome set to enable high-quality research into the management of equinus deformity.

Development of a functional prototype of a SMART (Sensor-integrated for Monitoring And Remote Tracking) foot abduction brace for clubfoot treatment: a pre-clinical evaluation

Purpose

Recurrences following clubfoot correction by the Ponseti method can be prevented by regular use of a foot abduction brace (FAB) until the child is four to five years old. However, there is a lack of an objective method to measure actual hours of brace usage. The aim was to develop a functional prototype of a SMART (Sensor-integrated for Monitoring And Remote Tracking) clubfoot brace to record accurate brace usage and transmit the data remotely to healthcare providers treating clubfoot.

Methods

A collaborative team of engineers and doctors was formed to investigate various types of sensors and wireless technologies to develop a functional prototype of a SMART brace.

Results

Infrared sensors were used to detect if the feet were placed inside the shoes and magnetic Hall effect sensors to detect that the shoes were latched on to the bar of the existing FAB. Brace usage data were captured by the sensors every 15 minutes and stored locally on a data card. A Bluetooth low energy (BLE)-based wireless transmission system was used to send the data daily from the brace to the remote cloud server via a smartphone application. Accurate brace usage data could be recorded by the sensors and visualized in real time on a web-based application in a pre-clinical setting, demonstrating feasibility in clinical practice.

Conclusion

The low-cost SMART brace prototype that we have developed can accurately measure and remotely transmit brace usage data and has the potential to transform caregivers’ behaviour towards brace adherence, which could result in a tangible reduction in recurrence rates.

Development of a core outcome set for idiopathic clubfoot management

Aims

This study aims to define a set of core outcomes (COS) to allow consistent reporting in order to compare results and assist in treatment decisions for idiopathic clubfoot.

Methods

A list of outcomes will be obtained in a three-stage process from the literature and from key stakeholders (patients, parents, surgeons, and healthcare professionals). Important outcomes for patients and parents will be collected from a group of children with idiopathic clubfoot and their parents through questionnaires and interviews. The outcomes identified during this process will be combined with the list of outcomes previously obtained from a systematic review, with each outcome assigned to one of the five core areas defined by the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT). This stage will be followed by a two round Delphi survey aimed at key stakeholders in the management of idiopathic clubfoot. The final outcomes list obtained will then be discussed in a consensus meeting of representative key stakeholders.

Conclusion

The inconsistency in outcomes reporting in studies investigating idiopathic clubfoot has made it difficult to define the success rate of treatments and to compare findings between studies. The development of a COS seeks to define a minimum standard set of outcomes to collect in all future clinical trials for this condition, to facilitate comparisons between studies and to aid decisions in treatment.

Successful Ponseti-treated Clubfeet at Age 2 Years: What Is the Rate of Surgical Intervention After This?

BACKGROUND

In recent decades, nonoperative Ponseti casting has become the standard of care in the treatment of idiopathic clubfoot. However, the rate of recurrence, even after successful Ponseti treatment is not insignificant. The purpose of this study was to determine the future rate, timing, and type of surgery needed in patients whose idiopathic clubfeet treated by Ponseti casting were considered successful at the age of 2 years.

METHODS

Inclusion criteria for this retrospective study were patients under 3 months with idiopathic clubfoot treated exclusively by Ponseti casting, who had successful outcomes at 2 years of age without surgery, and who had at least 5 years of follow-up. The total number of surgical interventions in the age range 2 to 5 and above 5 years, the number and type of procedures performed, and the timing of surgery were reviewed.

RESULTS

Three hundred thirty-six patients with a total of 504 clubfeet fulfilled the inclusion criteria. One hundred twenty-two of these 336 patients (36.3%) eventually underwent surgical intervention. Between 2 and 5 years of age, 79 patients (23.5%) with 104 feet (20.6%) underwent surgery. The most common procedures performed between 2 and 5 years were limited (a la carte) in scope: tibialis anterior tendon transfer, posterior release, plantar fascia release, and repeat tendo-Achilles lengthening. At age above 5 years, 53 patients (20.1%) with 65 feet (16.9%) underwent surgery. Ten of these 53 patients had already undergone surgery between 2 and 5 years of age. The procedures most commonly performed were similar.

CONCLUSIONS

In patients with idiopathic clubfoot who reached 2 years of age with successful outcomes from Ponseti cast treatment, ∼35% eventually underwent surgical intervention, mostly limited (a la carte), to regain or maintain a plantigrade foot. The most commonly performed procedures include tibialis anterior tendon transfer, posterior capsular release, plantar fascia release and repeat tendo-Achilles lengthening, either in isolation or in combination. However, before considering surgery, the need for these procedures can, and should, be minimized by recasting recurrent deformities using Ponseti method.

The reliability and validity of the weight-bearing lunge test in a Congenital Talipes Equinovarus population (CTEV)

Question

What is the intra and inter-rater reliability and concurrent validity of the weight-bearing lunge test within a Congenital Talipes Equinovarus population?

Design

Test retest design for reliability and validity. The measure was taken, following preconditioning of the participants, using distance from wall, angle at distal posterior tibia using a digital inclinometer and the iPhone level function, twice by each rater. The raters included a clinician, clinician in training and a parent/carer.

Outcome measures

Weight bearing lunge test as a measure of ankle dorsiflexion.

Results

Twelve children aged 5–10 years were eligible to participate and consented, along with their parents. Intra-reliability of distance measures for all raters were good to excellent (ICC clinician 0.95, ICC training clinician 0.98 and ICC parent 0.89). Intra-rater reliability of the iPhone for all raters was good (ICCs > 0.751) and good to excellent for the inclinometer (ICC clinician 0.87, ICC training clinician 0.90). Concurrent validity between the clinician’s and parents distance measure was also high with ICC of 0.899. Inter-rater reliability was excellent for distance measure (ICC = 0.948), good for the inclinometer (ICC = 0.801) and moderate for the iPhone (ICC = 0.68). Standard error of measurement ranged from 0.70–2.05, whilst the minimal detectable change ranged from 1.90–5.70.

Conclusion

The use of the WBLT within this CTEV population has demonstrated good to excellent reliability and validity amongst clinicians, clinicians in training and parents/carers, supporting its use as an assessment measure of dorsiflexion range of motion. There is support for parents/carers to use the WBLT at home as a monitoring assessment measure which may assist with early detection of a relapse.

A retrospective study of idiopathic clubfoot managed by Ponseti method using Pirani and Dimeglio scoring, in Indian population: a minimum 3-year follow-up

Congenital talipo-equino-varus (CTEV) is one of the most common congenital deformities affecting children in India with an incidence of 1.19/1000 live births. Ponseti treatment regimen has been established as the gold standard of care for idiopathic clubfoot. We present quantitative and qualitative analysis of the results of Ponseti management in early presenting idiopathic clubfoot cases, with a minimum follow-up of three years after correction. We retrospectively analysed the data of 122 children (comprising a total of 191 feet) who were treated for clubfoot by the standard Ponseti method with a minimum 3-year follow-up post-correction at our clinic. All cases were treated under the supervision of a single senior Paediatric Orthopaedic Surgeon. The mean age at onset of treatment was 2.3 months. Mean follow-up period was 4.2 years. The mean number of casts applied was 6.7. The mean duration of treatment until the application of splint was 9.5 weeks. The mean Pirani score at the commencement of treatment was 4.5. At the completion of treatment (around 3.6 years of age), the Dimeglio score was 'Benign' (Good) in 106 cases, 'Moderate' (Fair) in 11 cases and 'Severe/Very Severe' (Poor) in 5 cases. The P-value was calculated to be 0.8 for the sex-wise comparison of the treatment outcome. Ponseti method of nonoperative treatment for idiopathic clubfeet remains a gold standard for all cases treated during infancy. Identifying atypical clubfeet is important as their prognosis ought to be guarded. Despite facing problems at various stages of management, adhering to the basic treatment principles laid down by Ponseti helps in achieving good outcomes in majority. Level of Evidence: IV.

'Return to the New Normal': Innovative Solutions for Safe Ponseti Casting in Clubfoot Clinics during the COVID-19 Pandemic

Clubfoot treatment using the Ponseti method has been severely impacted as a result of lockdown measures implemented by several countries during the COVID-19 pandemic. As clubfoot clinics begin phased re-opening, we describe various innovative techniques to protect patients and healthcare providers during delivery of clubfoot treatment services. In addition to standard social distancing measures and sanitization protocols, we report a simple and innovative technique of 'barrier casting' or 'ring-fencing' to potentially reduce the risk of droplet infection and airborne transmission during clubfoot casting and tenotomy. A transparent, disposable plastic drape is set up as a curtain and serves as an impermeable barrier between the caregiver and healthcare provider performing the casting or tenotomy. The plastic drape is cheap (< US$ 1.5), easily available and can be used effectively even in low- and middle-income countries which have a high patient load. We have utilized these innovative techniques in 43 consecutive patients since clinic re-opening and are satisfied that they are effective, economical and easily reproducible even in countries with limited resources. Innovative techniques, which have the potential to reduce the risk of disease transmission, will help in the rapid recovery of clubfoot treatment services as countries emerge from months of lockdown.

Changes in the Management of Clubfoot Cases During COVID-19 Pandemic-A Survey Among Orthopaedic Specialists

PURPOSE

The on-going COVID-19 pandemic has curtailed the established practice norms of many ailments including clubfoot. We conducted a survey to study the changes in the clubfoot treatment practices, Achilles tenotomy methods, and the role along with the possible impact of teleconsultation during this pandemic.

METHODS

A web-based survey was conducted using a questionnaire prepared on Google forms. The link for this questionnaire was sent to Indian Orthopaedic specialists with a special interest in clubfoot management via a social messaging platform.

RESULTS

127 eligible responses were analysed. Of them, 67% respondents were in practice for more than 10 years. During the study period, 30.7% of doctors did not perform any casting; 66.9% performed casting in 1-5 cases per week and only 2.4% performed casting in more than five cases per week. A statistically significant difference was noted in the number of doctors who performed casting in less than five cases per week and the doctors who performed casting in more than five cases per week, before and during the COVID-19 pandemic. 30.7% of doctors deferred doing Achilles tenotomy during the study period, and among those who performed one, a significant number of them avoided tenotomy under general anaesthesia.

CONCLUSION

The COVID-19 pandemic has significantly impacted clubfoot treatment practices during the lockdown period in India. Significant reductions in the number of cases, and a reduction with changes in Achilles tenotomy practices were noted too. However, whether this had any adverse influence on the eventual outcome in these feet is yet to be determined.
