Early Radiographic Characteristics of the Lateral Talocalcaneal Angle and its Predictive Significance for Relapse in Patients With Idiopathic Clubfoot Treated With the Ponseti Method.

In order to evaluate the early radiographic characteristics of the lateral talocalcaneal (L-TC) angle in patients with idiopathic clubfoot (ICF) and to investigate its prognostic significance for relapse after initial treatment with the Ponseti method. We retrospectively included 151 patients (96 males and 55 females; 227 feet) with ICF treated at our Institution between January 2005 and December 2014. The age at initial treatment was less than 6 months, and radiographs were obtained within 3 months of the Achilles tenotomy (mean age: 2.3 months; range: 0.77-6.8). All patients were followed up for at least 7 years (range, 7-18). The participants' feet were classified into 3 groups: relapsed (Group A), not relapsed (Group B), and normal foot groups which consisted of healthy feet in patients with unilateral ICF (Group C). All angle measurements were expressed in degrees. Forty-seven ICF feet in 33 patients relapsed, while 180 feet in 118 patients did not, and the age at relapse was 5.92 ± 1.91 years. Seventy-five normal feet were included in Group C. The average L-TC angle in Group A and B patients was 33.57° ± 12.05° and 39.37° ± 12.55°, respectively, while Group C was 49.61° ± 9.11°. A significant difference was found among the 3 groups of patients (F = 31.48, p < .001). The L-TC angle cut-off value below which a recurrence could be predicted was 36.1° (sensitivity, 74.47%). The L-TC angle of ICF patients treated using the Ponseti method were reduced compared to normal feet. An L-TC angle of <36.1° has relative value in predicting ICF relapse.

Functional, clinical, and radiological outcomes of split anterior tibial tendon transfers in patients with sequelae of congenital talipes equinovarus.

OBJECTIVE: This retrospective analysis aimed to assess the effectiveness of Split Tibialis Anterior Tendon Transfer (Split TATT) in treating residual idiopathic congenital talipes equinovarus (CTEV) deformities. METHODS: 15 patients (20 feet) with CTEV, with a mean age of 6.4 ± 3.2 years, initially treated with Ponseti casting, underwent Split TATT. Clinical and radiological evaluations, including Diméglio and Garceau scores, dorsiflexion, and X-ray measurements, were conducted preoperatively and post-operatively at a minimum 2-year follow-up. RESULTS: Significant improvements were observed in Diméglio and Garceau scores. Dorsiflexion increased by an average of 3°, and radiological analysis revealed nuanced changes. Despite a weak Kappa coefficient, positive trends in dorsiflexion and Garceau scores were noted. Preoperative Garceau scores did not reliably predict postoperative results. CONCLUSION: Split TATT demonstrates promising results in improving muscular balance and functional outcomes in CTEV. While radiological changes are subtle, positive trends in clinical scores indicate meaningful outcomes. LEVEL OF EVIDENCE: IV Retrospective study.

Conventional Versus Accelerated Ponseti in the Management of Cases of Idiopathic Clubfoot: A Systematic Review and Meta-Analysis.

This study aimed to compare the outcomes of the accelerated and standard Ponseti method for clubfoot pathology by constructing a systematic review and meta-analysis of relevant randomized controlled trials and nonrandomized comparative studies. A systematic search was conducted to identify the relevant studies through PubMed, Google Scholar, and Cochrane depending on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The keywords used included "accelerated" AND "standard" AND "Ponseti" AND "clubfoot" AND "Congenital Talipes Equinovarus" AND "CTEV" AND "prospective comparative design" AND "randomized trial." We conducted this analysis among 13 studies that met the criteria adopted in this review where eight studies were prospective comparative studies, and five studies were randomized prospective comparative studies which were published in the period between 2015 and 2022. Statistically, accelerated Ponseti showed superior impact over standard Ponseti considering the duration of treatment (22.53 days vs. 40.61 days, p<0.001). No significant difference was reported between the two methods considering final Pirani score (0.64 vs. 0.56, p=0.194), number of casts (5.23 vs. 5.25, p=0.425), rate of tenotomy (66.2% vs. 63.1%, OR=1.246, 95% CI: 0.86-1.80, p=0.245), relapse rate (9.51% vs. 8.54%, OR=1.126, 95% CI: 0.68-1.86, p=0.642) and complication rate (14.4% vs. 13.1%, OR=1.130, 95% CI: 0.58-2.19, p=0.717). We concluded that the accelerated Ponseti method could achieve comparable efficacy to the standard method in terms of post-procedure Pirani score, tenotomy rate, relapse rate, complications rate, and number of casts needed by the patients with advantage of requiring shorter duration of treatment which is associated with more patient's compliance.

Pain behavior of children with bilateral idiopathic clubfoot undergoing Ponseti casting and the effect of non-pharmaceutical pain-relieving agents.

INTRODUCTION: This study prospectively investigated the pain response and physiological parameters [heart rate (HR) and oxygen saturation (SpO2)] during sequential casting in bilateral clubfoot. Additionally, it explored the role of non-nutritive sucking and human care contact on the observed responses during casting. METHODS: Subjects were allotted to control group (Group A with no intervention) and two intervention groups (Group B: non-nutritive sucking intervention, Group C: human care contact intervention). Neonatal Infant Pain Score (NIPS), heart rate (HR), and oxygen saturation (SpO2) were used to assess the response. RESULTS: The three groups matched in age and gender characteristics of the participants. Pain response was noted across all groups. The left foot demonstrated a statistically significant preexisting tachycardia which rose further during casting (p < 0.01). Intergroup comparisons revealed that the alteration for NIPS during casting was in following sequence (Group A > C > B, p < 0.00001). The effect of interventions offered in Group B and C lasted in the post-cast period as well (B > C). CONCLUSION: The clubfoot child exhibited moderate pain response during casting of both feet. A tachycardia was noted prior to initiation of second cast which further exaggerated with subsequent cast. Pacifier (non-nutritive sucking) intervention produced better control of pain response than human care contact during casting for both feet.

A Prospective Study on Functional Outcomes of Serial Cast Correction in Congenital Talipes Equinovarus (CTEV) by Ponseti Method.

INTRODUCTION: Congenital talipes equinovarus (CTEV), often known as clubfoot, is one of the most common congenital deformities of the foot and ankle, affecting one in every 1,000 live births. The deformity has four components: ankle equinus, hindfoot varus, forefoot adductus, and midfoot cavus. The Ponseti casting technique of CTEV management has proven to be more effective, generating higher positive outcomes and lesser complications than conventional surgical methods. METHODS: This study was conducted in a tertiary care teaching hospital centre in southern Rajasthan, India. Twenty cases with 31 feet of untreated clubfoot were included. The deformity was scored according to Pirani's scoring system. Manipulation and serial corrective casts were applied at weekly intervals according to Ponseti's method. Percutaneous tendoachilles tenotomy was done whenever required (guided by Pirani score). Final results were calculated using the Pirani score, noted before putting the patient on foot abduction orthosis. RESULTS: In our study, the average number of casts required for full correction was 6.5. Heel cord tenotomy was required in 27 feet (87%) to achieve full correction. Final Pirani score significantly improved from an average of 4.8 on presentation to 0.055 after completion of casting. CONCLUSION: We conclude that the Ponseti technique of CTEV correction significantly reduces the need for invasive surgical procedures along with being exceedingly safe, effective, and affordable. The Ponseti technique of cast correction is crucial and provides a painless, plantigrade, cosmetically acceptable foot with higher functional outcomes and minimal complications.

Genetic Role in Recurrence of Idiopathic CTEV: A Systematic Review.

Background: Congenital Talipes Equinovarus (CTEV) is a multitude of deformities involving equinus, varus, adductus, and cavus deformities. Clubfoot affects 1 in every 1000 infants born worldwide, with various incidences according to geographical areas. It has been previously hypothesized that the possible genetic role in Idiopathic CTEV (ICTEV) might have a treatment-resistant phenotype. However, the genetic involvement in recurrent ICTEV cases is yet to be determined. Aim: To systematically review existing literature regarding the discovery of genetic involvement in recurrent ICTEV to date to further understand the etiology of relapse. Methods: A comprehensive search was performed on medical databases, and the review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. A comprehensive search was performed on several medical databases: PubMed (MEDLINE), Scopus, the Cochrane Library, and European PMC on May 10, 2022. We included studies reporting patients with recurring idiopathic CTEV or CTEV of unknown cause after treatment, reporting whole-genetic sequencing, whole-exome sequencing, Polymerase Chain Reaction, or Western blot analysis as methods of genetic analysis (intervention) and providing results of idiopathic CTEV genetic involvement. Non-English studies, literature reviews, and irrelevant articles were excluded. Quality and risk of bias assessments were performed using Newcastle-Ottawa Quality Assessment Scale for non-randomized studies where appropriate. The authors discussed data extracted with the primary outcome of gene(s) frequency being reported of their involvement in recurrent ICTEV cases. Results: Three pieces of literature were included in this review. Two studies analyzed the genetic involvement in CTEV occurrence, while one analyzed the protein types found. Discussion: With included studies of less than five, we could not perform other forms of analysis apart from qualitatively. Conclusion: The rarity of literature exploring the genetic etiology of recurrent ICTEV cases has been reflected in this systematic review, giving opportunities for future research.

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.

What exactly is "foot abduction" during management of idiopathic clubfoot in clinical practice?

PURPOSE: There is however gross ambiguity regarding the use of term "foot abduction" in clubfoot treatment. We measured below defined angles at different stages of clubfoot treatment to decipher their precise interpretation. METHODS: In a prospective evaluation of 25 unilateral clubfeet in infants' age less than six months treated with Ponseti technique, clinical leg foot and thigh foot angle were measured at talar head reduction (LHT0), pre-tenotomy, and post-tenotomy stage. A "normal" reference was available in the form of measurements of contralateral limb. RESULTS: Talar head (LHT0) was reduced at mean leg foot angle of 26 degrees. The corresponding pre- and post-tenotomy angles were 42.6 and 50.0 degrees, respectively. The reference leg foot angles for contralateral limb were 49.8 degrees. The thigh foot angle for LHT0, pre-tenotomy, post-tenotomy, and contralateral side were, respectively, 39.2, 56, 68, and 65.6 degrees. There was an additional tibial external rotation component of mean 13.4 degrees (SD 4.5) in the thigh foot angle when compared to the leg foot angle at tenotomy. This increased to 18 degrees (SD 3.4) post-tenotomy. CONCLUSIONS: The study suggested that the foot abduction described in the "Ponseti Manual" probably intends thigh foot rather than leg foot angles. There was a significant difference in the angles when talar head reduced and tenotomy was decided. The foot abduction is an ambiguous term which should be replaced by the more specific leg or thigh foot abduction angle.

Non-zero Pirani score in corrected clubfoot due to empty heel: A prognostic dilemma.

Purpose: The aim of this study was to track the correction of individual components of Pirani scoring system (PSS) over the manipulation and tenotomy phase of Ponseti casting method in idiopathic clubfoot. Additionally, non-zero PSS scores were analysed to find out the residual deformities. Methods: The included feet were assessed initially according to the six component PSS. The individual scores of each component of midfoot and hindfoot were scored at each visit till the final follow up. The final scoring was done before the start of the bracing phase of the feet (with or without tenotomy). Results: Evaluation was performed for 42 feet in 28 infants (14 bilateral) with mean age of 42.5 ± 39.2 days (range, 15-150 days). All the six components of PSS showed a significant change from the first cast till the pre tenotomy cast. Post tenotomy, there was a significant change in the scores of posterior crease (0.4 ± 0.2 to 0.1 ± 0.1, p < 0.001) and rigid equinus (0.8 ± 0.3 to 0.1 ± 0.2, p < 0.001). 66.7 % (28/42) of the feet had an abnormal empty heel sign of either 0.5 [22/42 (52.3 %)] or 1 [6/42 (14.4 %)] at initiation of bracing. Conclusions: The individual components of Pirani scoring system changed to a variable extent as the treatment progressed. Curvature lateral border and talar head reached normalcy prior to tenotomy. Posterior crease and rigid equinus showed a significant reduction after tenotomy. The non-zero empty heel component may require careful interpretation both post treatment and during follow ups.

Bilateral Pseudoaneurysms Following Percutaneous Achilles Tenotomy for Congenital Talipes Equinovarus.

Pseudoaneurysm following percutaneous tendoachilles (TA) tenotomy is a rare complication found in children with congenital talipes equinovarus (CTEV). It is postulated that associated aberrant vascular anatomy in combination with CTEV may be the underlying aetiology. In this case report, we describe a case of a toddler who developed bilateral pseudoaneurysms following percutaneous tendoachilles tenotomy and explore the management and outcome in relation to this. Based on this case report and a review of the literature, the consistent clinical findings of swelling and/or discolouration due to pseudoaneurysm occur at three weeks post-tenotomy, and should raise suspicion for the diagnosis. Furthermore to the best of our knowledge, this is the first case report of bilateral pseudoaneurysms in the same setting, and we propose the possibility of an aberrant vessel arising from the peroneal artery that may be prone to injury.

Can immediate postoperative radiographs predict outcomes in pediatric clubfoot?

BACKGROUND: The goal of treatment for pediatric idiopathic clubfoot is to enable the patient to comfortably walk on his or her soles without pain. However, currently accepted treatment protocols are not always successful. Based on the abnormal bone alignment reported in this disease, some studies have noted a correlation between radiographic characteristics and outcome, but this correlation remains debated. AIM: To assess the correlation between immediately postoperative radiographic parameters and functional outcomes and to identify which best predicts functional outcome. METHODS: To predict the outcome and prevent early failure of the Ponseti's method, we used a simple radiographic method to predict outcome. Our study included newborns with idiopathic clubfoot treated with Ponseti's protocol from November 2018 to August 2022. After Achilles tenotomy and a long leg cast were applied, the surgeon obtained a single lateral radiograph. Radiographic parameters included the tibiocalcaneal angle (TiCal), talocalcaneal angle (TaCal), talofirst metatarsal angle (Ta1st) and tibiotalar angle (TiTa). During the follow-up period, the Dimeglio score and functional score were examined 1 year after surgery. Additionally, recurring events were reported. The correlation between functional score and radiographic characteristics was analyzed using sample and multiple logistic regression, and the optimal predictor was also identified. RESULTS: In total, 54 feet received approximately 8 manipulations of casting and Achilles tenotomy at a mean age of 149 days. The average TiCal, TaCal, Ta1st, and TiTa angles were 75.24, 28.96, 7.61, and 107.31 degrees, respectively. After 12 mo of follow up, we found 66% excellent-to-good and 33.3% fair-to-poor functional outcomes. The Dimeglio score significantly worsened in the poor outcome group (P value < 0.001). Tical and TaCal showed significant differences between each functional outcome (P value < 0.05), and the TiCal strongly correlated with outcome, with a smaller angle indicating a better outcome, each 1 degree decrease improved the functional outcome by 10 percent. The diagnostic test revealed that a TiCal angle of 70 degrees predicts an inferior functional outcome. CONCLUSION: The TiCal, derived from lateral radiographs immediately after Achilles tenotomy, can predict functional outcome at 1 year postoperatively, justifying its use for screening patients who need very close follow-up.

Early developmental milestones in patients with idiopathic clubfoot treated by Ponseti method.

Background: Idiopathic clubfoot, also referred to as congenital talipes equinovarus (CTEV), is one of the most common lower limb deformities observed in newborns, leading to significant functional impairment if untreated. The aims of this study were to (1) assess the developmental milestones in patients with CTEV treated by the Ponseti technique, and to compare them to the unaffected controls; (2) evaluate the possible correlation between developmental milestones, severity of the deformity, and number of casts. Materials and methods: Seventy-nine subjects were divided into two groups, CTEV group (43 patients; 72 feet) and control group (36 patients). Age, sex, affected side, attainment of babbles (BAL), independent gait (IG), and combined word (CW) were recorded for all patients. In patients with CTEV, Pirani Score (PRS), number of casts (NC), and clinical outcome were collected according to the Clubfoot Assessment Protocol (CAP), The American Orthopedic Foot and Ankle Score (AOFAS), and Foot and Ankle Disability Index (FADI). Results: IG was achieved later later than the unaffected controls by 12/43 patients (27.9%) with CTEV and 3/36 patients in the control group (8.3%) (p = 0.04) and in a mean time of 16.8 ± 3.5 months and 13.2 ± 2.7 months, respectively (p = 0.001). In the CTEV group the mean value of CAP was 98.6 ± 4.7, of AOFAS of 98.4 ± 4.4 and of FADI equal to 99.9 ± 0.44. There were no statistically significant differences for BAL and CW; and no correlation with PRS, NC, or clinical score were identified. Conclusion: CTEV patients managed by the Ponseti technique achieve independent gait later than the unaffected controls, although they do so within the age limit of developmental. On the other hand, the Ponseti treatment has no impact on attainment of language development.

Congenital Dislocation of the Knee: Idiopathic or Arthrogryposis?

Fetal akinesia associated with fixed joints is a common cause for suspicion of arthrogryposis multiplex congenita, a severe condition with heterogeneous etiology. We present the case of a rarer but more benign condition, congenital knee dislocation. The authors report the case of a 27-year-old woman medicated with levetiracetam for epilepsy whose prenatal ultrasound at 22 weeks of gestational age revealed bilateral clubfoot, permanent extension of the inferior limbs with internal knee rotation, normal amniotic fluid quantity, and fetal echocardiography. The remaining ultrasounds revealed similar results. Prenatal genetic testing revealed no pathological findings. The pregnancy was otherwise uneventful. A female newborn was delivered at 39 weeks by cesarean section, with no need for resuscitation. She presented with bilateral knee hyperextension and clubfoot, spontaneous movements, and normal mobility in all other joints. The remaining physical examination and brain and hip ultrasound on the second day of life were normal. These findings were compatible with idiopathic congenital dislocation of the knee (CDK). The patient was undergoing treatment with favorable evolution and adequate neurodevelopment, at the time of this report.  This case describes a diagnostic workup with the exclusion of severe syndromic pathologies, namely arthrogryposis. Despite the initial suspicion of arthrogryposis, a condition with a poor prognosis, this infant presented a more benign disease with favorable evolution.

Anterior tibial tendon transfer in idiopathic clubfoot: does the outcome differ with the initial treatment? Proposed classification to surgical indication.

PURPOSE: To establish parameters and propose a radiographic classification for foot adduction/supination deformities to assist the indication of Garceau procedure. Secondly, to investigate whether the outcome of Garceau surgery depends on the initial treatment used, peritalar release, or the Ponseti method, and verify the maintenance of correction until skeletal maturity. METHODS: Prospective cohort study, with follow-up evaluations in 2009 and 2019. Fifty-three consecutive patients (71 feet) with idiopathic congenital clubfoot (ICCF) were divided into two groups according to the initial treatment used: peritalar release (group I) or Ponseti method (group II). All patients underwent Garceau procedure. The patients were evaluated clinically and radiographically using the American Orthopedic Foot Association (AOFAS) score for ankle and hindfoot. A radiographic classification is proposed based on the adduction by talo-first metatarsal angle on dorsoplantar view and supination by the elevation of the head of the first metatarsal on lateral view, both weight-bearing. RESULTS: In the first clinical evaluation, the mean score on the AOFAS was 87 points in group I and 86 points in group II. In the second evaluation, group I had mean AOFAS of 92 points and group II of 94 points. No statistical differences were found between the two groups, neither between the first and the second evaluation. In the radiographic evaluation, the adduction deformity obtained an average correction of 4° in group I and 3.6° in group II; in supination deformity, the average depression of the first metatarsal head in relation to the ground was 6.7 mm in group I and 7.5 mm in group II, with no statistical difference between the two evaluations, indicating the correction was maintained until skeletal maturity. CONCLUSION: Garceau transfer is capable of correcting residual deformities in adduction/supination of mild and moderate degrees, regardless of the initial treatment, and maintaining the correction until skeletal maturity. The proposed radiographic classification might help to objectively indicate the surgical procedure.

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. LEVEL OF EVIDENCE: Level II - prognostic study.

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. LEVEL OF EVIDENCE: II.

Concomitant Talocalcaneal Coalition as a Risk Factor for Early Relapse Following Ponseti Treatment of Idiopathic Clubfoot.

Concomitant talocalcaneal coalition (TCC) in idiopathic clubfeet is not well documented in the literature. The purpose of this study was to describe our experience with very early relapsing idiopathic clubfeet associated with TCC. Although cases have been successfully treated with the Ponseti casting method, all recurred within 2 months of removing the final cast. A single-centre cohort of twelve feet in eight patients treated by a single surgeon between 2006 and 2020 was investigated retrospectively. Recurred cavus with variable degrees of equinus was the earliest findings noted. TCC was incidentally detected during the open reduction of the earliest three feet in our series. Afterwards, ultrasonography was advised as a screening tool for detecting an associated anomaly; however, only the use of magnetic resonance imaging (MRI) was 100% accurate in diagnosing concurrent TCC. All coalitions were cartilaginous and the posterior facet was most commonly involved facet. The average age was 18 months for the coalition resection and open reduction of a dislocated talonavicular joint, and the average duration of follow-up was 52 months. None of the patients showed clinical signs of relapse at the latest follow-up. We recommend that an associated TCC should be considered in very early relapsing idiopathic clubfoot cases.

Objective analysis of intermediate-term outcome of the Ponseti technique: a review of the experience from Los Angeles.

The Ponseti method of manipulative treatment for clubfoot deformity became widely adopted by pediatric orthopaedic surgeons beginning in the mid-1990s. The technique allows correction of most idiopathic clubfeet using gentle manipulation and cast application. The treatment represents a marked advance over past efforts to gain correction of the foot through extensive release surgery. In 2006, we began a Clubfoot Clinic at the Orthopaedic Institute for Children in Los Angeles, California dedicated to managing clubfoot patients using Ponseti's method. An IRB-approved database of patient-related, treatment related, and demographic variables was assembled and used to ascertain the outcome of treatment as well as to address parental questions regarding certain aspects of treatment. Here, we present a review of our body of work, which has improved clinical decision making as well as our ability to better inform our patients' parents regarding the treatment and prognosis of the Ponseti method. Studies from our institution showed that while relapses and the need for extra-articular tibialis anterior tendon transfer (TATT) surgery remain common to the Ponseti method, these events do not adversely affect overall patient function or satisfaction. These findings were not unlike those of classic studies reported from Ponseti's institution. We conclude that the Ponseti method is not only a technique to achieve initial correction of an idiopathic clubfoot, but also how to manage relapses that will inevitably occur in many patients. While relapses and tendon transfer surgery are likely to remain common with this treatment method, these events do not adversely affect overall patient function or satisfaction. The parents of infants whose clubfeet are managed using the Ponseti method should be counselled accordingly.

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.

Radiological tarsal bone morphology in adolescent age of congenital clubfeet treated with the Ponseti method.

BACKGROUND: Major abnormalities of tarsal bone shape after surgical clubfoot treatment are well known from the literature. The Ponseti method has gained widespread acceptance in primary treatment of congenital clubfeet. Despite the longtime experience, data regarding the development of tarsal bones after this treatment are still rare. The aim of the study was therefore to evaluate radiographic parameters describing tarsal bone shape of clubfeet after Ponseti treatment and compare them to age-matched healthy feet. METHODS: Twenty two consecutive severe clubfeet in 14 patients were investigated by repeated diagnostic ultrasound during the corrective process. Extent and temporal course of correction were documented with standardized X-rays after a mean follow-up of 12 years (between the ages of 10-14 years) and compared to a group of age-matched normal feet. RESULTS: Reliability testing for all X-ray parameters showed good to excellent results. In comparison to the control group, all parameters except the radius of the trochlea (RT) were significantly altered in clubfeet with highest differences shown for the anterior talar motion segment (ATM), talonavicular coverage (TNC) and the talometatarsal index (TMT-Index). Differentiation between minor and major deformities showed significant differences only for the front tarsal index (FTI). CONCLUSIONS: Tarsal bone shape of clubfeet treated by the Ponseti method differs significantly from normal feet. One of the most pronounced and clinically relevant difference of the clubfoot talus compared to the normal talus is the markedly reduced anterior talar motion segment.
