Bracing in clubfoot: do we know enough?

Psychosocial Impacts of Idiopathic Clubfoot on Parents and Children: A Scoping Review Protocol

BACKGROUND/OBJECTIVES

Idiopathic clubfoot is a complex pediatric foot deformity. The Ponseti technique is widely regarded as the standard for correcting deformities, and treatment compliance is essential for preventing relapse. Examining psychosocial effects on parents and/or children during clubfoot treatment provides valuable insights for improving compliance. This scoping review will map the existing literature on the psychological and social effects experienced by parents and/or children with idiopathic clubfoot. It also aims to examine the assessment tools used to measure these impacts and identify factors influencing treatment compliance.

METHODS

This review will adhere to the Joanna Briggs Institute (JBI) guidelines for scoping reviews. The search will include databases such as Scopus, Web of Science, EBSCOhost, MEDLINE, and PsycINFO and focus on studies published in the last 10 years. This review will include quantitative, qualitative, and mixed-method studies that investigate the psychological and social effects experienced by parents or affected children of any age with idiopathic clubfoot. Reporting will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) extension guidelines. The screening and data extraction process will involve two independent reviewers. The analysis will be descriptive and qualitative.

RESULTS

The findings will be presented in tables and a narrative summary.

CONCLUSION

This review may guide health practitioners in developing evidence-based interventions to improve treatment adherence.

Duration and outcome of orthotic treatment in children with clubfoot - a four-year follow-up national register study of Swedish children born between 2015 and 2017

BACKGROUND

The Ponseti method for treating clubfoot consists of initial treatment with serial casting accompanied by achillotenotomy if needed, followed by the maintenance phase including treatment with a foot abduction orthosis (FAO) for at least four years. This study aimed to examine the duration, course, and outcome of orthotic treatment in children with clubfoot.

METHODS

321 children with clubfoot, born between 2015 and 2017, registered in the Swedish Pediatric Orthopedic Quality Register (SPOQ), were included in this prospective cohort study. Data on deformity characteristics and orthotic treatment were extracted. For children with bilateral clubfoot, one foot was included in the analysis.

RESULTS

Of the 288 children with isolated clubfoot, 274 children (95.5%) were prescribed an FAO, and 100 children (35%) changed orthosis type before 4 years of age. Of the 33 children with non-isolated clubfoot, 25 children (76%) were prescribed an FAO, and 21 children (64%) changed orthosis type before 4 years of age. 220 children with isolated clubfoot (76%), and 28 children with non-isolated clubfoot (84%) continued orthotic treatment until 4 years of age or longer. Among children with isolated clubfoot, children ending orthotic treatment before 4 years of age (n = 63) had lower Pirani scores at birth compared to children ending orthotic treatment at/after 4 years of age (n = 219) (p = 0.01). It was more common to change orthosis type among children ending orthotic treatment before 4 years of age (p = 0.031).

CONCLUSIONS

The majority of children with clubfoot in Sweden are treated with an FAO during the maintenance phase. The proportion of children changing orthosis type was significantly greater and the Pirani score at diagnosis was lower significantly among children ending orthotic treatment before 4 years of age. Long-term follow-up studies are warranted to fully understand how to optimize, and individualize, orthotic treatment with respect to foot involvement and severity of deformity.

The Importance of Having a Single, Dedicated Medical Team to Treat Congenital Talipes Equinovarus Using the Ponseti Method: A Retrospective Analysis of Treatment Outcomes After 3 Years of Follow-up

BACKGROUND

Congenital talipes equinovarus (CTEV) is a relatively common pediatric orthopaedic disorder and a frequent cause of disability in adult populations. The Ponseti method has emerged as the generally preferred for treating children with CTEV. Strict adherence to this technique's basic principles is critical to achieving favorable outcomes. In 2013, our institution decided that every case of pediatric CTEV would be treated by a single dedicated medical team. The present study aimed to compare the treatment outcomes of children with CTEV treated using the Ponseti method in period I (multiple surgeons) versus those in period II (single dedicated team).

PATIENTS AND METHODS

We included respectively the children with CTEV treated using the Ponseti method in Geneva University Hospitals' pediatric units from 2007 to 2018. Data on patient demographics, clinical characteristics, and the treatment outcomes were collected. The primary outcome was the number of relapsed feet (treatment failure) after 3 years of follow-up. The 2 periods' outcomes were compared using χ 2 and independent Student t -tests. Run charts were used to report yearly rates of complications, minor and major recurrences, treatment failure, brace noncompliance, and feet that underwent tenotomy.

RESULTS

A total of 48 feet (32 patients) and 42 feet (29 patients) in periods I and II were included. The periods showed similar rates for participants' characteristics. The run charts illustrated the overall improvements in treatment outcomes in period II. A total of 8 relapsed feet (5 patients) were reported, all during period I.

CONCLUSIONS

Since all the pediatric CTEV patients at our institution began to be treated by a single dedicated medical team, we have observed a decrease in all recurrences and complications and an absence of treatment failure. These results highlight the importance of the continuity of care and strict adherence to the Ponseti method.

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.

Barriers and facilitators to lower extremity orthotic compliance in the pediatric population: A scoping review of the literature

Despite the purported benefits of lower extremity orthotics in the literature, pediatric compliance rates remain low. This scoping review synthesized the available literature regarding barriers and facilitators to lower extremity orthotic compliance in the pediatric population using the framework of the International Classification of Functioning, Disability and Health: Children and Youth (ICF). A comprehensive search of MEDLINE, EMBASE, and CINAHL was conducted on May 11, 2021, and of PsycInfo on May 12, 2021. Article reference lists and gray literature were also searched. A total of 81 articles were included. Factors described in at least four articles were labeled as universal barriers or facilitators. In the International Classification of Functioning, Disability and Health: Children and Youth domain of Body Functions/Body Structures, universal barriers were present in the global mental functions, experience of self and time, sensory functions, function of joints and bones, and structures related to the skin subcategories, with no universal facilitators identified. For the Activity Limitations/Participation Restrictions domain, one universal facilitator was identified in the mobility subcategory. In the Environmental Contextual Factors domain, universal barriers were found in the attitudes of immediate and extended family and societal attitude subcategories, with both universal barriers and facilitators found in support & relationships: immediate and extended family, support and relationships: health professionals, services, systems, and policies, and products and technology. The reviewed literature strongly emphasizes the importance of proper orthotic fit and comfort, and the child's experience of self, for lower extremity orthotic compliance, along with multiple environmental factors.

Prospective, Randomized Ponseti Treatment for Clubfoot: Orthopaedic Surgeons Versus Physical Therapists

BACKGROUND

Clubfoot is a common congenital foot deformity in children. The Ponseti method of serial casting has become the standard of care in clubfoot treatment. Clubfoot casting is performed in many centers by both orthopaedic surgeons and physical therapists (PTs); however, direct comparison of outcomes and complications of this treatment between these providers is limited. This study prospectively compared the outcomes of patients with clubfoot treated by these 2 groups of specialists.

METHODS

Between January 2010 and December 2014, all patients under the age of 12 months with a diagnosis of clubfoot were included. Patients were randomized to an orthopaedic surgeon (MD) group or a PT group for weekly serial casting. Main outcome measures included the number of casts required to achieve correction, clinical recurrence of the deformity, and the need for additional surgical intervention.

RESULTS

One hundred twenty-six infants were included in the study. Patient demographics and characteristics (sex, race, family history of clubfoot, laterality, and severity of deformity) were similar between treatment groups, with the only significant difference being the mean age of entry into the study (5.2 weeks in the MD group and 9.2 weeks in the PT group, P=0.01). Mean length of follow-up was 2.6 years. The number of casts required trended to a lower number in the MD group. There was no significant difference in the rates of clinical recurrence or additional surgical intervention between groups.

CONCLUSIONS

Ponseti casting for treatment of clubfoot performed by orthopaedic surgeons and PTs results in equivalent outcomes without any difference in complications. Although the number of casts required trended to a lower number in the MD group, this likely did not result in any clinical significance, as the difference in cast number equaled <1 week's difference in the overall duration of serial casting.

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.

Assessment of early Achilles tenotomy in the newborn idiopathic pes equinovarus

We aimed to evaluate the clinical and radiological results of early Achilles tenotomy which was performed before Ponseti method in PEV deformities. 37 feet of 26 patients with Dimeglio type 3 and 4 deformities were included in the study. Unlike the classical Ponseti method, patients underwent a mini-open Achilles tenotomy before the first cast. 6-month follow-up of the foot deformities were assessed using Dimeglio classification clinically and lateral talocalcaneal and tibiocalcaneal angles radiologically. There were 20 male and 6 female patients with the median age of 14 days (4-37 days) and 11 bilateral and 15 unilateral deformities. The average follow-up period was 7 months (6-12 months). The mean Dimeglio scores before the Achilles tenotomy and Dimeglio score at the 6 th month follow-up were 14 (11-16) and 4 (4-6) for the right feet, 13 (10-16) and 4 (4-6) for the left feet respectively. The mean number of casting was 3.8 ± 0.4 for right feet and 3.7 ± 0.4 for left feet. The mean talocalcaneal angle was 24 ± 8.2 degrees for the right feet and 27 ± 8.2 degrees for the left feet. The mean tibiocalcaneal angle was 69 ± 12 for the right feet and 72 ± 14 degrees for the left feet. Early Achilles tenotomy can decrease the total number of cast for deformity correction in Ponseti method and provide good clinical and radiological outcomes at 6 th month follow-up in severe PEV deformities according to Dimeglio classification.

Anatomical Structures Responsible for CTEV Relapse after Ponseti Treatment

Relapse of deformity after a successful Ponseti treatment remains a problem for the management of clubfoot. An untreated varus heel position and restricted dorsal flexion of the ankle are the main features of recurrences. We analyze the anatomical structures responsible for these recurrences. Materials and methods: During 5 years, 52 children with CTEV (Congenital Talipes Equino Varus) were treated with casts according to the Ponseti method, with a mean number of 7 casts. Closed percutaneous tenotomy was performed in 28 infants. Children were followed monthly and treated with the continuous use of a molded cast. We had 9 children with relapsed clubfeet. During the standing and walking phase, they had a fixed deformity with a varus position of the heel and dorsal flexion of the ankle <10 d. They were surgically treated with the posterolateral approach. Results: In all patients, we found a severe thickening of the paratenon of the Achilles in the medial side, with adhesions with the subcutaneous tissue. The achilles after the previous tenotomy was completely regenerated. The achilles was medially displaced. Conclusions: A severe thickening of the paratenon of the achilles and adhesions with the subcutaneous tissue are anatomical structures in fixed relapsed cases of clubfoot. We treated our patients with an appropriate surgical release.

Measuring Foot Abduction Brace Wear Time Using a Single 3-Axis Accelerometer

The recommended treatment for idiopathic congenital clubfoot deformity involves a series of weekly castings, surgery, and a period of bracing using a foot abduction brace (FAB). Depending on the age of the child, the orthotic should be worn for periods that reduce in duration as the child develops. Compliance is vital to achieve optimal functional outcomes and reduce the likelihood of reoccurrence, deformity, or the need for future surgery. However, compliance is typically monitored by self-reporting, which is time-consuming to implement and lacks accuracy. This study presents a novel method for objectively monitoring FAB wear using a single 3-axis accelerometer. Eleven families mounted an accelerometer on their infant's FAB for up to seven days. Parents were also given a physical diary that was used to record the daily application and removal of the orthotic in line with their treatment. Both methods produced very similar measurements of wear that visually aligned with the movement measured by the accelerometer. Bland Altman plots showed a -0.55-h bias in the diary measurements and the limits of agreement ranging from -2.96 h to 1.96 h. Furthermore, the Cohens Kappa coefficient for the entire dataset was 0.88, showing a very high level of agreement. The method provides an advantage over existing objective monitoring solutions as it can be easily applied to existing FABs, preventing the need for bespoke monitoring devices. The novel method can facilitate increased research into FAB compliance and help enable FAB monitoring in clinical practice.

Unilateral limb orthosis for maintenance of deformity correction following treatment of clubfoot with Ponseti technique: a systematic review

The systematic review study aimed to investigate the following details in the clubfoot children treated with the Ponseti technique: (1) to review the various designs and prescriptions of unilateral limb orthosis described in literature; (2) to find the outcome following use of this orthosis, especially patient adherence and recurrence; (3) comparison with standard bilateral limb foot abduction orthosis. A literature search was performed for articles published in 'Pubmed (includes Medline indexed journals)' electronic databases for broad key words: 'Clubfoot or CTEV or congenital talipes equinovarus', 'orthosis or brace or splint'. Included were studies that addressed the treatment of idiopathic clubfoot in children up to 2 years of age using the Ponseti technique and use of unilateral limb orthosis for the subsequent maintenance phase. We excluded studies reporting Ponseti technique for nonidiopathic clubfoot, child age older than 2 years at the time of primary treatment, studies where unilateral limb orthosis was used as a tool for primary correction of all or some components of clubfoot and design descriptions of orthosis without practical usage data. Of the 1537 articles from the database, 10 articles were included in the final review. Most studies were retrospective, underpowered and had a short term follow-up. In some series, the use of this orthosis was driven by personal experiences and regional preferences rather than a just scientific explanation. The tested designs were variable and nonstandardized. Being less restrictive, unilateral limb orthosis may have an edge over bilateral limb orthosis in terms of patient adherence. The available comparative studies however showed inferiority of unilateral orthoses when compared to the bilateral limb orthosis in preventing recurrences in clubfoot treatment. There is insufficient evidence to support use of unilateral limb orthosis for maintenance of deformity correction following treatment of clubfoot with the Ponseti technique. Their use was found associated with high recurrence rates.

Sensor based braces: Challenges ahead

Sensor based brace is a new technology driven initiative to address the adherence issues associated with clubfoot treatment. It encompasses various engineering fields (sensors, batteries, data transfer) to measure precise brace wear timings. Still in preliminary usage, yet they have lead to several significant findings; foremost being that caretakers tend to over report their brace usage. Enhanced surveillance and reinforcements is thus possible with sensor devices as defaulters can be picked up early. The introduction of these devices in common practice is postulated to lessen relapse rates by upto 40%. However, many challenges obscure the path of newer braces. Robust study designs and longer follow up is lacking in majority of studies detailing sensor based clubfoot braces. None of the currently available studies demonstrate effectiveness of patient interventions/changes based on the research data. Behavioral changes in caretakers may be difficult to achieve and could require repeated reinforcements. Since braces need to be worn for prolonged periods in clubfoot treatment, sensor data generated per patient would be colossal. It's processing and interpretation would be an uphill task. The cost of advanced inventory may burden ongoing clubfoot care programmes in low income countries. There is also a possibility that the newer technology may tone up the bracing protocol into a highly sophisticated and supervised medical intervention rather than a simplified maintenance phase. Till further development and evidence, sensor based clubfoot braces may find their initial application for high risk groups susceptible to 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 effect of COVID-19 on children with congenital talipes equinovarus in a tertiary service in the United Kingdom

During the coronavirus disease 2019 (COVID-19) pandemic, many aspects of healthcare have been hindered. The primary aim of this study was to identify what the impact of COVID-19 was on the delivery of outpatient care for children with congenital talipes equinovarus deformity (CTEV) at a large tertiary hospital in the UK. This study reviewed the patients who commenced their Ponseti treatment between March and September 2020, representing the cohort who received hands-on care during the first wave of the COVID-19 pandemic. Equivalent 6-month periods were searched in 2019 and 2018 as control cohorts. This study included a total of 45 children (72 affected feet) presenting for treatment of clubfoot. Twenty-three babies were seen with CTEV in 2020. For the same time period in 2018 and 2019, 11 babies were treated each year. The distance commuted to by families was higher in 2020 compared to 2019 and 2018, although the difference did not reach statistical significance (P = 0.301). Treatment with Ponseti casting was commenced at a mean age of 52 days, with no statistically significant differences between cohorts (P = 0.758). Using strict precautions, the Ponseti service at a large tertiary hospital in the UK grew in size and successfully provided treatment for children presenting with CTEV during the first wave of the COVID-19 pandemic. This study has shown that with careful protocols in place, children with CTEV can be treated successfully during times of pandemic, thereby reducing the post-pandemic burden of older children requiring treatment.

Ponseti treated idiopathic clubfoot - outcome predictive factors in the test of time: analysis of 500 feet followed for five to 20 years

PURPOSE

To investigate a set of risk factors on the outcome of Ponseti treated idiopathic clubfeet (ICF).

METHODS

This study was approved by the institutional review board. A retrospective analysis of prospectively gathered data over a 20-year period, at a single dedicated clubfoot clinic. Records of 333 consecutive infants with 500 ICF were analyzed. Initial Pirani score, number of casts, need for tenotomy, foot abduction brace compliance and functional score had been documented. The need for surgery after initial correction was the outcome measure. All children were followed by the same team throughout the study period. Descriptive statistics, chi-squared and multivariate analysis were performed.

RESULTS

In total, 82 children (24%) with 119 feet (23.8%) were operated on, with 95.1% of feet being operated up to the age of nine years. There was a significant correlation between the Pirani score at presentation and the number of surgical procedures (chi-squared = 79.32; p < 0.001). Achilles tenotomy was done in 94.8% of patients. Pirani score of > 4.5 before casting was strongly associated with increased surgical risk (odds ratio = 1.95). When six to eight cast changes were needed, surgical prospect was 2.9 more, increasing to 11.9 when nine or more casts were needed.

CONCLUSION

Foot severity and number of cast changes were the strongest predictors for future surgery. Estimation of the risk of deformity recurrence after initial correction may help in tailoring a cost-effective personal treatment and follow-up protocol. Personalized focused protocol will help patients and caregivers and will reduce expenses.

A modification of the Ponseti method for clubfoot management: a prospective comparative study

PURPOSE

We aimed to compare our parent-based exercise programem's efficacy with the foot abduction brace (FAB) Ponseti manipulation as a retention programme.

METHODS

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.

RESULTS

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).

CONCLUSION

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.

The functional method: experience from the Robert Debré Hospital

Background

In the 1970s a conservative treatment for clubfoot (CF) deformity based on daily physiotherapy combining specific sequences was developed: the French functional method (FFM). Over time, the FFM technique has improved and additional measures have been introduced. The aim of this study was to report mid-term and long-term results of clubfeet treated conservatively by the FFM at birth.

Methods

All patients consecutively treated for clubfoot by the FFM between 1993 and 2010 were prospectively included. Initial severity was assessed by the Dimeglio classification. All patients were followed up by the same treating surgeon until skeletal maturity. Final assessment was performed using the International Clubfoot Study Group evaluation system (ICFSG).

Results

A total of 779 feet were included. Surgery was required in 41% of cases (mean age 2.0±0.1 years). The incidence of surgery significantly decreased after the introduction of percutaneous Achilles tenotomy (PAT) in 2000 (63.4% vs. 29.6%). At latest evaluation (mean follow-up 12±0.2 years), 86% of patients had excellent or good outcomes (mean ICFSG was 1.83±0.1). Mean ankle dorsiflexion was 10° in non-idiopathic CF and 12.1° in idiopathic CF. Eleven percent of the idiopathic clubfeet exhibited decreased ankle function (0–10°). There were no cases of overcorrection into excess ankle dorsiflexion or rocker bottom foot deformities.

Conclusions

Current team was the funding institution of the FFM and several modifications were proposed over times to improve outcomes. Eighty-six percent of feet had excellent to good outcomes according to the ICFSG score, with minimal residual deformities (ankle dorsiflexion between 0° and 10°, calcaneal-thigh angle between 10° and 20°) or insufficient radiological correction (defined by talo-calcaneal angle between 10° and 20°) at latest follow-up.

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.

The Influence of Achilles Tenotomy and Compliance with Foot Abduction Orthosis on the Relapse Rate of Ponseti Treatment for Idiopathic Clubfoot: A Regional Study

The Ponseti method for treating idiopathic clubfoot is based on gradual manipulations and corrective plaster castings followed by a years-long period of use of a foot orthosis. The role of surgery is limited. The factors that may affect outcome and their influence are subject of controversy. The aim of the study is to systematically and objectively evaluate the results of Ponseti treatment in our region of Southern Israel and focus on the role of the Achilles tenotomy and compliance to foot orthosis as factors that may influence outcome. The use of Ponseti method was retrospectively studied (level of evidence IV) by searching computerized medical files and clinical photos. The severity of deformity was evaluated by Dimeglio score (D-score) at baseline and at last examination. During 2006-2014, 57 children with idiopathic clubfoot (total 90 feet) were enrolled. An Achilles tenotomy was performed in 55/90 (61.1%) of the feet. If the D-score was 15 or higher there was a 20% increase in the incidence of Achilles tenotomy. The parental compliance had a weak protective effect against relapse. The treatment of idiopathic clubfoot by the Ponseti method was successful and reliable, proving efficiency and universality of the method. A dominant predictor for relapse was not seen. An incidental observation was that extended time in cast may buffer the adverse effects of low compliance rate. Although the initial severity, or compliance to braces are important, there may be other factors that affect the outcome such as, accuracy of the casting technique, time in the cast, access to a dedicated clubfoot clinic, cooperation with nurses and pediatricians, economic status that allows purchase of new generation of braces, cultural perception, and education level of the patient population are some examples.

Idiopathic clubfoot treatment and heterogeneity of current therapeutic strategies: The Ponseti method versus the French functional method (a systematic review)

BACKGROUND

Since Hippocrates, the treatment of idiopathic clubfoot has undergone many changes, with surgical techniques and conservative approaches evolving over the centuries. Today, a wide variety of practices exist in France and throughout the world; consequently, the treatment of idiopathic clubfoot remains controversial, but the Ponseti method and the functional method seem to stand out. Nevertheless, has one of them demonstrated superiority?

METHODS

The purpose of this review is to compare these two methods. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 recommendations, this research was conducted on Pubmed, Web of Science, and 1Findr. Only articles concerning patients with moderate or severe idiopathic clubfoot (10-17 on the Dimeglio scale) treated early using the Ponseti method or the functional method were eligible.

RESULTS

After reviewing 49 studies, seven published between 2008 and 2018 were selected: five prospective cohort studies, one retrospective cohort study, and one meta-analysis. Each method, according to morphological and kinetic criteria, seems to have advantages that the other does not have.

CONCLUSIONS

Although the Ponseti method is becoming the gold standard and appears more appropriate in poor countries, it is impossible to affirm its superiority over the functional method. Therefore, the combination of their advantages deserves attention: a hybrid method could be an appealing prospect for the future.

A Community Audit of 300 "Drop-Out" Instances in Children Undergoing Ponseti Clubfoot Care in Bangladesh-What Do the Parents Say?

Introduction: Drop-out before treatment completion is a vexing problem for all clubfoot clinics. We and others have previously identified better engagement with parents as a crucial method of ameliorating incomplete clubfoot treatment, which increases deformity relapse. Materials and methods: The novel use of community facilitators enabled an audit of over 300 families who had dropped-out from a child’s clubfoot treatment. A questionnaire standardized the parent interviews. Parents were encouraged to present for clinical review of their child’s clubfeet. Results: When treatment was discontinued for six months, 309 families were audited. A social profile of families was developed, showing that most lived in tin houses with one working family member, indicating low affluence. Family issues, brace difficulty, travel distances, and insufficient understanding of ongoing bracing and follow-up were the main reasons for discontinuing treatment. Overt deformity relapse was found in 9% of children, while half of the children recommenced brace use after review. Conclusions: Identifying families at risk of dropping out from clubfoot care enables support to be instigated. Our findings encourage clinicians to empathize with parents of children with clubfoot deformity. The parent load indicator, in parallel with the initial clubfoot severity assessment, may help clinicians to better appreciate the demand that treatment will place on parents, the associated risk of drop-out, and the opportunity to enlist support.

Is the Denis Browne Splint a Myth? A Long-Term Prospective Cohort Study in Clubfoot Management using Denis Browne Splint Versus Daily Exercise Protocol

The Ponseti technique is successful in idiopathic clubfoot management. However, the leading cause of relapse and recurrence is nonadherence to the Denis Brown bracing protocol. This necessitates more extensive soft tissue surgeries. Based on a detailed up-to-date search, we have found that no other studies provide such a modified Ponseti technique. This study is unique, as it depends on using specific stretching exercises instead of bracing during management. Between August 2009 and June 2019, a consecutive series of 194 isolated idiopathic clubfoot patients (251 feet) were included in this study. The mean follow-up was 93 months (range 72 to 146), mean 91.8 months. All patients underwent a clinical and functional assessment using the Laaveg-Ponseti score and radiological assessments. There were 132 boys (68.1%) and 62 girls (31.9%), a male-to-female ratio of 2:1. The mean age at initiation of treatment was 14.9 days. According to the Laaveg-Ponseti score, 51.7% yielded excellent results, 35.3% yielded good results, 11.55% yielded fair results, and 1.59% yielded poor results. Bracing noncompliance has been identified as a major cause for treatment failure. This presented exercise protocol not only eliminates the need for bracing and reduces the cost for the affected individuals but also provides excellent clinical and radiographic end results, comparable to the original treatment protocol using the Denis Brown brace.

Clubfoot for the primary care physician: frequently asked questions

PURPOSE OF REVIEW

This review aims to provide primary care physicians with updates on recent literature regarding clubfoot and answer questions asked by parents and caregivers of children with clubfoot. The topics discussed include prenatal counseling, relapse after Ponseti treatment, long-term outcomes following successful treatment of clubfoot, and the effect of diagnosis and treatment on the parent or caregiver.

RECENT FINDINGS

Clubfoot is one of the most commonly searched orthopaedic conditions on the internet by parents. There is a lack of evidence-based guidelines on clubfoot worldwide. Recent systematic reviews have identified emerging evidence of genetic and modifiable risk factors that lead to clubfoot. Patients treated by the Ponseti method show better ankle power and strength compared with those treated with surgery for residual deformity or recurrence.

SUMMARY

The treatment of clubfoot is a long and involved process. Exposure to and familiarity with the Ponseti method will aid primary care physicians and parents in the optimization of children's clubfoot deformity correction using largely nonoperative management.
