Abstract
Objective Evaluate whether the experience of the surgeon could reduce Ponseti treatment time, and a number of cast changes, and the evolution of the Pirani Score. Methods 2 reference centers were evaluated. At Institution 1, 254 patients with idiopathic clubfoot (403 feet) were included, and at Institution 2, 32 patients (51 feet). At institution 1 (mentor), 3 intervals of 5 years each were analyzed. At the Institution 2 (trainee), 1 interval of 5 years was analyzed. Results Patients treated by the mentor had fewer casts compared with the trainee (p < 0.001). At Institution 1, the three mentor intervals showed differences in the number of casts (p < 0.05). A statistically significant difference was observed only in the first mentor interval (2000 to 2005, average of 3.47 casts) compared with the 2 other intervals (2005 to 2010; average of 2.6 casts and 2011 to 2015; average of 2.79 casts; p < 0.0001). Pirani score decreases the most until the third clinic visit. Conclusion The mentor's greater expertise was associated with fewer casts and shorter time to obtain correction in isolated clubfoot, especially right after the first 5 years of practice. Progression of the Pirani score in both institutions occurs between the first and the third casts. Level of Evidence III; Therapeutic Study, Retrospective Comparative Study.

Diagnostics (Basel) 2024; 14:117. [PMID: 38201425 PMCID: PMC10795686 DOI: 10.3390/diagnostics14010117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/01/2024] [Accepted: 01/03/2024] [Indexed: 01/12/2024] Open
Abstract
Prenatal diagnosis of clubfoot traditionally relied on two-dimensional ultrasonography. To enhance diagnosis and predict postnatal outcomes, we examined the parameters that differentiate pathological clubfoot using three-dimensional ultrasonography. In our retrospective study, we examined the findings of prenatal ultrasound and the postnatal outcomes of pregnancies with suspected congenital clubfoot between 2018 and 2021. Based on the three-dimensional perspective, we measured the angles of varus, equinus, calcaneopedal block, and forefoot adduction and compared the sonographic variables between the postnatal treated and non-treated groups. We evaluated 31 pregnancies (47 feet) with suspected clubfoot using three-dimensional ultrasonography. After delivery, a total of 37 feet (78.7%) underwent treatment involving serial casting only or additional Achilles tenotomy. The treated group showed significantly greater hindfoot varus deviation (60.5° vs. 46.6°, p = 0.026) and calcaneopedal block deviation (65.6° vs. 26.6°, p < 0.05) compared to the non-treated group. The calcaneopedal block had an area under the curve of 0.98 with a diagnostic threshold of 46.2 degrees (sensitivity of 97%, specificity of 90%, positive predictive value of 97%, and negative predictive value of 90%). During prenatal evaluation of clubfoot using three-dimensional ultrasonography, the calcaneopedal block deviation has the potential to predict postnatal treatment.

Abstract
BACKGROUND The Pirani scale is used for the assessment of Ponseti-managed clubfoot. Predicting outcomes using the total Pirani scale score has varied results, however, the prognostic value of midfoot and hindfoot components remains unknown. The purpose was to (1) determine the existence of subgroups of Ponseti-managed idiopathic clubfoot based on the trajectory of change in midfoot and hindfoot Pirani scale scores, (2) identify time points, at which subgroups can be distinguished, and (3) determine whether subgroups are associated with the number of casts required for correction and need for Achilles tenotomy. METHODS Medical records of 226 children with 335 idiopathic clubfeet, over a 12-year period, were reviewed. Group-based trajectory modeling of the Pirani scale midfoot score and hindfoot score identified subgroups of clubfoot that followed statistically distinct patterns of change during initial Ponseti management. Generalized estimating equations determined the time point, at which subgroups could be distinguished. Comparisons between groups were determined using the Kruskal-Wallis test for the number of casts required for correction and binary logistic regression analysis for the need for tenotomy. RESULTS Four subgroups were identified based on the rate of midfoot-hindfoot change: (1) fast-steady (61%), (2) steady-steady (19%), (3) fast-nil (7%), and (4) steady-nil (14%). The fast-steady subgroup can be distinguished at the removal of the second cast and all other subgroups can be distinguished at the removal of the fourth cast [ H (3) = 228.76, P < 0.001]. There was a significant statistical, not clinical, difference in the total number of casts required for correction across the 4 subgroups [median number of casts 5 to 6 in all groups, H (3) = 43.82, P < 0.001]. Need for tenotomy was significantly less in the fast-steady (51%) subgroup compared with the steady-steady (80%) subgroup [ H (1) = 16.23, P < 0.001]; tenotomy rates did not differ between the fast-nil (91%) and steady-nil (100%) subgroups [ H (1) = 4.13, P = 0.04]. CONCLUSIONS Four distinct subgroups of idiopathic clubfoot were identified. Tenotomy rate differs between the subgroups highlighting the clinical benefit of subgrouping to predict outcomes in Ponseti-managed idiopathic clubfoot. LEVEL OF EVIDENCE Level II, prognostic.

Abstract
INTRODUCTION Parents of children with clubfoot are likely to inquire about the need for tenotomy and about any factors that may be predictive. The present study was done to identify factors that may help predict the need for tenotomy in children undergoing Ponseti treatment for idiopathic clubfoot. METHODS A prospective observational study was conducted on patients under 5 years of age with idiopathic clubfoot and no previous treatment history treated at Hospital and Rehabilitation Centre for Disabled Children. The relationship between the Pirani score, Dimeglio score, age, and passive ankle dorsiflexion (DF) and the need for heel cord tenotomy was analyzed using appropriate statistical methods. RESULTS Of 83 patients (125 feet) with a mean age of 6 months, 93 feet (74.4%) required a percutaneous tenotomy. The mean initial Pirani and Dimeglio score for 125 club feet was 4.5 (SD=1.68) and 13.5 (SD=6.1), respectively. The mean initial passive ankle DF was -40.4 (SD=22.31). The Dimeglio ( P =0.000), Pirani scores ( P =0 .000), and passive ankle DF ( P =0.000) showed significant association with the need for tenotomy. CONCLUSIONS This study shows a strong association between initial Pirani and Demiglio scores and initial passive ankle DF as predictive of a heel cord tenotomy. However, age, sex, and laterality were not associated with the need for tenotomy.

Abstract
BACKGROUND Although the Ponseti method has been used with great success in a variety of nonidiopathic clubfoot deformities, the efficacy of this treatment in clubfeet associated with Down syndrome remains unreported. The purpose of this study is, therefore, to compare treatment characteristics and outcomes of clubfoot patients with Down syndrome to those with idiopathic clubfoot treated with the Ponseti method. METHODS An Institutional Review Board-approved, retrospective review of prospectively gathered data were performed at a single pediatric hospital over an 18-year period. Patients with either idiopathic clubfeet or clubfeet associated with Down syndrome who were less than 1 year of age at the outset of treatment were treated by the Ponseti method, and had a minimum of 2 year's follow-up were included. Initial Dimeglio score, number of casts, need for heel cord tenotomy, recurrence, and need for further surgery were recorded. Outcomes were classified using the Richards classification system: "good" (plantigrade foot +/- heel cord tenotomy), "fair" (need for a limited procedure), or "poor" (need for a full posteromedial release). RESULTS Twenty clubfeet in 13 patients with Down syndrome and 320 idiopathic clubfeet in 215 patients were identified. Average follow-up was 73 months for the Down syndrome cohort and 62 months for the idiopathic cohort. Down syndrome patients presented for treatment at a significantly older age (61 vs. 16 d, P =0.00) and with significantly lower average initial Dimeglio scores than the idiopathic cohort (11.3 vs. 13.4, P =0.02). Heel cord tenotomy was performed in 80% of the Down syndrome cohort and 79% of the idiopathic cohort ( P =1.00). Recurrence rates were higher in the Down syndrome cohort (60%) compared with the idiopathic group (37%), but this difference was not statistically significant ( P =0.06). Need for later surgical procedures was similar between the 2 cohorts, though recurrences in the Down syndrome group were significantly less likely to require intra-articular surgery (8.3% vs. 65.5%, P =0.00). Clinical outcomes were 95% "good," 0% "fair," and 5% "poor" in the Down syndrome cohort and 69% "good," 27% "fair," and 4% "poor" in the idiopathic cohort ( P =0.01). CONCLUSIONS Despite the milder deformity and an older age at presentation, clubfeet associated with Down syndrome have similar rates of recurrence and may have better clinical outcomes when compared with their idiopathic counterparts. When deformities do relapse in Down syndrome patients, significantly less intra-articular surgery is required than for idiopathic clubfeet. LEVEL OF EVIDENCE Level III.

Abstract
Background and purpose - After initial clubfoot correction through Ponseti treatment, recurrence rates range from 26% to 48%. Even though various factors have been associated with increased recurrence risk, systematic assessments of the prognostic capacity of recurrence risk factors and their clinical relevance are lacking. Therefore we assessed clinically relevant prognostic factors for recurrent idiopathic clubfoot deformity after initial correction through Ponseti treatment. Methods - PubMed, Embase, Cinahl, and Web of Science were systematically searched for studies investigating the association between clinically relevant factors and recurrence rates. Prognostic factors were qualitatively assessed and included in the meta-analysis if ≥ 2 studies investigated the same factor and methods were comparable. Results - 34 articles were included in the qualitative synthesis, of which 22 were also included in the meta-analysis. Meta-analysis revealed that poor evertor muscle activity (OR = 255, 95% CI 30-2,190), brace non-compliance (OR = 10, CI 5-21), no additional stretching (OR = 31, CI 10-101), more casts (OR = 3.5, CI 1.6-7.8), lower education level of parents (OR = 1.8, CI 1.2-2.6), non-marital status of parents (OR = 1.8, CI 1.1-3.0), and higher Dimeglio scores (OR = 1.9, CI 1.2-3.3) were associated with higher recurrence rates. Interpretation - Brace non-compliance and poor evertor muscle activity have been identified as main recurrence risk factors and are therefore important to be closely monitored during clinical follow-up of clubfoot patients. Adding additional stretching during the bracing protocol might be promising in the quest to prevent relapse, but scientific evidence for clear clinical treatment recommendations is still limited.

Abstract
Clubfoot or talipes equinovarus deformity is one of the most common anomalies affecting the lower extremities. This review provides an update on the outcomes of various treatment options used to correct clubfoot. The ultimate goal in the treatment of clubfoot is to obtain a fully functional and pain-free foot and maintain a long-term correction. The Ponseti method is now considered the gold standard of treatment for primary clubfoot. Relapse is common after primary treatment with the Ponseti method, and other interventions are discussed that are used to provide for long-term successful outcomes.

Abstract
A prospective study to find a correlation between the severity of clubfoot and the number of casts required for the correction was conducted. The relationship of early relapse with the severity of the deformity was also studied. A total of 42 infants (61 feet) with primary and idiopathic clubfeet were included in the study. Previously treated and clubfeet due to secondary causes were excluded. All clubfeet were treated by the Ponseti method, and the Pirani score, Dimeglio score and Foot Bimalleolar (FBM) angle were taken at presentation and before every casting and at 6 months of follow-up. The average age of the child at presentation was 24 days, the average initial Pirani score was 4.172, the average initial Dimeglio score was 14.36 and the average FBM angle was 63.87 degrees. The average number of corrective casts given was 5.08 (range 2-8). The regression analysis showed a low correlation between Pirani and Dimeglio scores with the number of casts. There was no correlation between FBM angle and casting. Eleven of the 61 feet had a relapse (18%). Ten of 11 relapsed feet had a midfoot Pirani score of equal to or more than 2. The regression analysis shows a low correlation between Pirani and Dimeglio scores with the number of casts. There was no correlation between FBM angle and casting. Midfoot score equal to or more than 2 is a significant risk factor for relapse.

Abstract
The aim of this study is to evaluate children in middle childhood with clubfoot treated with Ponseti method vs posterior-only release and to compare their results to a control group with 4 modules (physical examination, gait study, radiographic measurements, and questionnaires). From 01/01/2004 until 01/01/2009, 31 children (45 feet) were treated with the posterior-only release protocol and 22 patients (34 feet) were treated with the Ponseti method. In 2016, patients were evaluated and compared with 25 children without neuromuscular disorders. Parents completed 3 outcome questionnaires. Radiographs evaluated residual deformity and osteoarthritis. A physical examination and a 3-dimensional gait analysis were performed to evaluate range of motion, kinematic, and kinetic data. Recurrence rate was similar between treatment groups; however, type of surgery to treat residual deformity was more aggressive in the posterior-only release (91% required major surgery), p = .024. Radiographic examination showed similar residual deformity with greater hindfoot varus in posterior-only release (68%), p = .02. Reduced cadence, increased stance dorsiflexion, calcaneus gait and forced eversion prior to swing were the main characteristics of gait in posterior-only release. Four (11%) feet treated with posterior-only release vs 11 (33%) feet treated with Ponseti method had a normal gait, p = .016. Our study showed that biomechanical function and long-term outcomes of children in middle childhood treated with the Ponseti method more closely compare with healthy individuals than those treated using posterior-only surgical technique.

Abstract
BACKGROUND Amniotic band syndrome (ABS) is a congenital disorder resulting in fibrous bands that can cause limb anomalies, amputations, and deformities. Clubfoot has been reported in up to 50% of patients with ABS. The purpose of this study is to compare treatment characteristics and outcomes of clubfoot patients with ABS to those with idiopathic clubfoot treated with the Ponseti method. METHODS An Institution Review Board (IRB) approved retrospective review of prospectively gathered data was performed at a single pediatric hospital over a 20-year period. Patients with either idiopathic clubfeet or clubfeet associated with concomitant ABS who were <1 year of age and treated by the Ponseti method were included. Initial Dimeglio score, number of casts, need for heel cord tenotomy, recurrence, and need for further surgery were recorded. Outcomes were classified as "good" (plantigrade foot±heel cord tenotomy), "fair" (need for a limited procedure), or "poor" (need for a full posteromedial release). RESULTS Forty-three clubfeet in 32 patients with ABS, and 320 idiopathic clubfeet in 215 patients were identified. Average age at last follow up was not different between ABS and idiopathic cohorts (7.4 vs. 5.2 y, P=0.233). Average Dimeglio score was lower in the ABS cohort (12.3 vs. 13.7, P=0.006). Recurrence rate was significantly higher in the ABS (62.8%) compared with idiopathic cohort (37.2%) (P=0.001). Clinical outcomes were significantly better in the idiopathic cohort (69.4% "good", 26.9% "fair", 3.8% "poor") compared with the ABS cohort (41.9% "good", 34.9% "fair", and 23.3% "poor") (P<0.001). Within the ABS cohort, no significant differences in clinical outcomes were found based upon location, severity, or presence of an ipsilateral lower extremity band. CONCLUSION Clubfeet associated with ABS have higher rates of recurrence, a greater need for later surgery, and worse clinical outcomes than idiopathic clubfeet. This information may prove helpful in counseling parents of infants with ABS associated clubfeet. LEVEL OF EVIDENCE Level III.

Abstract
Background Congenital clubfoot is one of the common congenital orthopaedic deformities. Pirani and Dimeglio scoring systems are two classification systems for measuring the severity of the clubfoot. However, the relation between the initial amount of each of these scores and the treatment parameters is controversial. Methods Patients with severe and very severe idiopathic clubfoot undergoing Ponseti treatment were entered. Their initial Pirani and Dimeglio scores, the number of castings as a short-term treatment parameter, and the recurrences as a long-term parameter until the age of three were prospectively documented. Results One hundred patients (143 feet) with mean age of 9.51 ± 2.3 days including 68 males and 32 females and the mean initial Pirani score of 5.5 ± 0.5 and the mean initial Dimeglio score of 17.1 ± 1.6 were studied. The incidence of relapse was 8.4 %( n = 12). The mean initial Pirani score (P < 0.001) and the mean initial Dimeglio score (P < 0.003) of the feet with recurrence were significantly more than the non-recurrence feet. The mean number of casts in the recurrence group (7 ± 0.9) was significantly more than the feet without recurrences (6.01 ± 1.04) (P = 0.002). The ROC curve suggested the Pirani score of 5.75 and the Dimeglio score of 17.5 as the cut-off points of these scores for recurrence prediction. Conclusion In our study, Pirani and Dimeglio scores are markedly related with more number of casts and recurrence in patients with severe and very severe clubfoot. Also, we have introduced new cut-off points for both classification systems for prediction of recurrence. To the best of our knowledge, this finding has not been introduced into the English literature.

Abstract
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.

Abstract
PURPOSE World over, age and various severity scores are among the foremost variables studied in relation to the number of casts in clubfoot. We studied the correlation between child's age at presentation, initial Pirani, Dimeglio scores to the number of Ponseti casts in Indian clubfoot children. Further, we matched Pirani versus Dimeglio scores at different severities of deformity to derive a correlation between them. METHODS We included 90 idiopathic clubfeet in 55 infants and scored them according to Pirani and Dimeglio grading systems. Syndromic, neurological, surgically intervened, atypical or complex clubfeet were excluded from the study. The number of casts before percutaneous tenotomy was counted. Correlations were calculated between corrective casts and age, Pirani, Dimeglio scores and their individual components. RESULTS Mean age of children was 63.7 days and average number of casts applied was 3.2. Age at presentation and number of casts had no correlation with r = 0.034 (p < 0.001). The correlation between initial Pirani score (average 5.39) and Dimeglio score (average 13.4) to number of casts was 0.35 (p < 0.001)and 0.56 (p < 0.0001) respectively. Among individual components of Pirani score, medial crease and rigid equinus had maximum correlation to the number of casts whereas empty heel sign had the lowest. For Dimeglio score, equinus and varus correlated the most and posterior crease the least. Pirani and Dimeglio scores were highly correlated (r = 0.87) to each other except for very supple or severe deformity. CONCLUSIONS In infancy, the age at presentation had no bearing on number of casts. Both scoring systems had positive correlation in terms of corrective casts for our population. The Dimeglio fared slightly better than Pirani scores.

Clubfoot treatment with Ponseti method-parental distress during plaster casting. J Orthop Surg Res 2020; 15:271. [PMID: 32680553 PMCID: PMC7368756 DOI: 10.1186/s13018-020-01782-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 07/02/2020] [Indexed: 11/23/2022] Open
Abstract
Background Clubfoot is one of the most prevalent musculoskeletal congenital defects. Gold standard treatment of idiopathic clubfoot is the conservative Ponseti method, including the reduction of deformity with weekly serial plaster casting and percutaneous Achilles tenotomy. It is well known that parents of children with severe and chronic illnesses are mentally stressed, but in recent studies regarding clubfoot treatment, parents were only asked about their satisfaction with the treatment. Largely unknown is parental distress before and during plaster casting in clubfoot. Therefore, we want to determinate first, how pronounced the parents’ worries are before treatment and if they decrease during the therapy. Second, we hypothesized that parents faced with an extreme deformity (high Pirani score), reveal more distress, than parents whose children have a less pronounced deformity (low Pirani score). Therefore, we wanted to investigate whether the Pirani score correlates with the parents’ mental resilience in relation to the therapy of the child as a global distress parameter. Methods To answer this question, we developed a questionnaire with the following emphases: Physical capacity, mental resilience, motion score, parents score, and child score with point scores 1 (not affected) to 6 (high affected). Subsequently, we interviewed 20 parents whose children were treated with clubfeet and determined the Pirani score of the infants at the beginning (T0) and at the end (TE) of the treatment with plaster casting. Results High values were obtained in child score (Mean (M) = 3.11), motion score (M = 2.63), and mental resilience (M = 2.25). During treatment, mental resilience improved (p = 0.015) significantly. Spearman correlation coefficient between Pirani score (T0) and mental resilience (T0) is 0.21, so the initial hypothesis had to be rejected. Conclusion The issues of the children are in the focus of parental worries concerning clubfoot treatment, especially the assumed future motion and the assumed ability to play with other children. Particular emphasis should be placed on educating parents about the excellent long-term results in the function of the treated feet especially as this topic shows the greatest parental distress.

Abstract
BACKGROUND The clubfoot is one of the commonly found congenital deformities in newborn. The Ponseti method is the most effective nonoperative clubfoot management method. It is based on understanding of pathoanatomy of clubfoot. For classifying severity of clubfoot, Pirani score is used. The number of cast required for clubfoot correction is dependent on its initial Pirani score. This study aimed on how the number of cast for correction of clubfoot deformity depends on starting time of casting and pretreatment Pirani score. MATERIALS AND METHODS This study comprises of 200 patients with 297 affected foot nonoperatively managed with Ponseti technique of casting. We measured initial and final Pirani scores of patients with different age groups. RESULTS We found that initial severity was less in 0-1 month age group children but mean casting number was more while initial severity was more in 1-2 month age group, the mean number of casting was less. Tenotomy requirement was also less in 1-2 month age group. CONCLUSION We concluded that casting according to the Ponseti method should be started in 1-2 months age group which shows better results than the other age groups in clubfoot.

Abstract
BACKGROUND We examined the correlation between initial Pirani and Dimeglio scores and their individual components to the number of casts for older clubfoot children. METHODS Twenty seven patients (39 feet) aged 2-11 years with idiopathic clubfeet were treated using the Ponseti technique and correlation with number of corrective casts calculated. The number of cast required was counted from application of primary cast to the time of initiation of the foot abduction orthosis. RESULTS Average 8.45 ± 2.31 (range, 4-13) casts were used for treatment. A low correlation (r = 0.203) was identified when total Dimeglio score was compared with the number of casts. No correlation was identified for Pirani score (r = 0.023). Among individual components, only cavus deformity had a significant positive correlation to cast numbers. CONCLUSIONS The Pirani and Dimeglio classifications still remain the most widely practiced clubfoot severity grading systems for the older clubfoot child. However, their prognostic value to predict the total cast duration from initial severity remains questionable.

Abstract
PURPOSE Diméglio (DimS) and Pirani (PirS) scores are the most commonly used scoring systems for evaluation of clubfoot, with many centres performing both. Interobserver reliability of their global score has been rated high in a few studies, but agreement of their subcomponents has been poorly investigated. The aim of the study was to assess interrater reliability of global scores and of items in a clinical setting and to analyse overlapping features of the two scores. METHODS Fifty-six consecutive idiopathic clubfeet undergoing correction using the Ponseti method were independently evaluated at each casting session by two trained paediatric orthopaedic surgeons using both scores. Interobserver reliability of collected data was analysed; a kappa coefficient > 0.60 was considered adequate. RESULTS For DimS and PirS, the Pearson correlation coefficients were 0.87 and 0.91 (p < .0001) respectively, and kappa coefficients were 0.23 and 0.31. Among subcomponents, kappa values were rated > 0.60 only for equinus and curvature of lateral border in PirS; muscular abnormality in DimS was rated 0.74 but a high prevalence index (0.94) indicated influence of scarce prevalence of this feature. All other items showed k < 0.60 and were considered to be improved.For overlapping features: posterior and medial crease showed similar agreement in the two systems, items describing equinus and midfoot adduction were much more reliable in PirS than in DimS. CONCLUSIONS In a clinical setting, despite a high correlation of evaluations for total scores, the interobserver agreement of DimS and PirS was not adequate and only a few items were substantially reliable. Simultaneous use of two scores seemed redundant and some overlapping features showed different reliability according to criterion or scale used. Future scoring systems should improve these limitations. LEVEL OF EVIDENCE Level I - Diagnostic studies.

Abstract
BACKGROUND The Dimeglio score (DS) is widely used to assess clubfoot severity, but its ability to predict long-term outcomes following Ponseti treated isolated clubfoot (IC) is controversial. This study tested the association between the initial DS and its individual parameters with the number of Ponseti clubfoot casts required to achieve correction and the rate of early recurrence following treatment. METHODS Data were retrospectively collected from patients who underwent treatment of IC between March 2012 and March 2015 and were followed for ≥2 years. DSs were collected at the initial casting visit. The number of Ponseti casts required to achieve clubfoot correction before tenotomy and recurrence of deformity were collected as the primary outcome variables. Recurrence was defined as any loss of correction leading to repeat casting or tenotomy during the bracing phase. Negative binomial and logistic regression analyses were used to test the association between the 8 Dimeglio parameters and number of casts and incidence of recurrence, respectively. RESULTS A total of 53 patients (37 male and 16 female) were included in the study. The median number of casts required to achieve an acceptable correction was 5 (range, 2 to 16). The incidence of recurrence was 24.53% (13/53). An increase in derotation, varus, equinus, muscle condition, and total DSs at the initial cast visit were associated with a significant (P<0.05) increase in the number of casts required to achieve an acceptable correction. The derotation parameter [rate ratio: 1.30, 95% confidence interval (CI): 1.13-1.50, P=0.0003] was most strongly associated with number of casts. Total DSs at initial visit was the only variable significantly associated with the incidence of deformity recurrence (odds ratio: 1.36, 95% confidence interval: 1.01-1.84, P=0.0482). CONCLUSION Initial DS is correlated with the number of casts required for correction in Ponseti treated IC. DS may help physicians establish realistic expectations for families with regard to the length of treatment and the possibility of recurrence following Ponseti treatment. LEVEL OF EVIDENCE Level II-retrospective prognostic study.

Abstract
Aims The Ponseti method is the benchmark treatment for the correction of clubfoot. The primary rate of correction is very high, but outcome further down the treatment pathway is less predictable. Several methods of assessing severity at presentation have been reported. Classification later in the course of treatment is more challenging. This systematic review considers the outcome of the Ponseti method in terms of relapse and determines how clubfoot is assessed at presentation, correction, and relapse. Patients and Methods A prospectively registered systematic review was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies that reported idiopathic clubfoot treated by the Ponseti method between 1 January 2012 and 31 May 2017 were included. The data extracted included demographics, Ponseti methodology, assessment methods, and rates of relapse and surgery. Results A total of 84 studies were included (7335 patients, 10 535 clubfeet). The relapse rate varied between 1.9% and 45%. The rates of relapse and major surgery (1.4% to 53.3%) and minor surgery (0.6% to 48.8%) both increased with follow-up time. There was high variability in the assessment methods used across timepoints; only 57% of the studies defined relapse. Pirani scoring was the method most often used. Conclusion Recurrence and further surgical intervention in idiopathic clubfoot increases with the duration of follow-up. The corrected and the relapsed foot are poorly defined, which contributes to variability in outcome. The results suggest that a consensus for a definition of relapse is needed.

Abstract
A total of 70 clubfeet were treated by a posterior above-knee cast (pressure points on the talus and on the first metatarsal) according to Ponseti method. At diagnosis, average Pirani score was 4.44, and mean time of treatment was 50.32 days. Overall, 27 (38.6%) clubfeet had only conservative treatment (5.29 casts) and 43 (61.4%) also had Achilles tenotomy (6.38 casts). At the end 61/70 feet (87.14%) had Pirani score 0; 10/70 feet (5.71%) had Pirani score 0.5. The Pirani score gain/cast was β=-0.432 (P<0.001). This new casting technique is safe and effective at avoiding some adverse issues related to the removal of the conventional cast.

Abstract
BACKGROUND It is challenging that some Ponseti method corrected clubfeet have a tendency to relapse. Controversies remain as to the implication of initial severity, representing the deformity degree, as well as number of casts needed, representing the treatment process, in predicting relapse. However, no study has been reported to take these 2 parameters into comprehensive consideration for outcome measurement. The purpose of this study is to investigate the correlation between the initial Pirani score and the number of casts required to correct the deformity in our series; to evaluate noncompliance as a risk factor of the deformity recurrence in Ponseti treatment; to test the validity and predictive value of a new proposed parameter, ratio of correction improvement (RCI) which is indicated by the initial Pirani scores divided by the number of casts. METHODS A total of 116 consecutive patients with 172 idiopathic clubfeet managed by Ponseti method were followed prospectively for a minimum of 2 years from the start of brace wearing. RCI value and the other clinical parameters were studied in relation to the risk of relapse by using multivariate logistic regression analysis modeling. RESULTS A positive correlation between the initial Pirani score and the number of casts required to correct the deformity was found in our series (r=0.67, P<0.01). There were 45 patients (39%) with brace noncompliance. The relapse rate was 49% (22/45). The odds ratio of relapse in noncompliant patients was 10 times more that in compliant patients (odds ratio=10.30 and 95% confidence interval, 2.69-39.42; P<0.01). The multivariate logistic regression analysis showed that there was significant association between relapse and RCI value. There were 42 patients (36%) with RCI value <1, among them, the relapse rate was 57% in 24 patients. The odds ratio of relapse in patients with RCI value <1 was 27 times more likely to relapse than those >1 (odds ratio=26.77 and 95% confidence interval, 5.70-125.72; P<0.01). CONCLUSIONS On the basis of the findings from our study, we propose the RCI to be a new parameter in predicting the risk of relapse in Ponseti method of clubfoot management. Early intervention is recommended to optimize the brace compliance particularly in case with lower RCI value. LEVEL OF EVIDENCE Level II-prognostic.

Abstract
Introduction: We assessed the role of the Pirani score in determining the number of casts and its ability to suggest requirement for tenotomy in the management of clubfoot by the Ponseti method. Materials and Methods: Prospective analysis of 66 (110 feet) cases of idiopathic clubfoot up to one year of age was done. Exclusion criteria included children more than one year of age at the start of treatment, non-idiopathic cases and previously treated or operated cases. Results: The initial Pirani score was (5.5±0.7) for the tenotomy group and the initial Pirani score was (3.3±1.6) for the non-tenotomy group. There was a significant difference between the initial Pirani score for the tenotomy and the non-tenotomy group with t= -7.9, df= 64 p<0.0001. The tenotomy group had a significantly higher number of casts (four to seven) compared to non-tenotomy group (two to five) t=-10.4, df=64, p<0.0001. Spearman’s rank correlation coefficient was significant and confirmed positive correlation between the initial Pirani score and the number of casts required to correct the deformity (r = 0.931, p<0.0001). Conclusion: Initial high Pirani score suggests the need for greater number of casts to achieve correction and probable need for tenotomy. The number of casts required in achieving complete correction increases with increase in the initial Pirani score. The initial high hindfoot score (2.5-3) signifies the probable need of a minor surgical intervention of percutaneous tendoachilles tenotomy. Based on the initial Pirani score, parents can be informed about the probable duration of treatment and the need for tenotomy.

Abstract
PURPOSE The Dimeglio and the Pirani scores are largely used to rate clubfoot at presentation and monitor correction. To date, the accuracy of these scores in predicting appropriate treatment is controversial. The aim of this study was to investigate the accuracy of Dimeglio and Pirani scores in predicting the number of casts and the need for tenotomy in clubfoot correction using the Ponseti method. METHODS Ninety-one consecutive feet (54 patients; mean age at presentation: 28 ± 15 days) undergoing clubfoot correction using the Ponseti method were prospectively followed from first casting to correction. All feet were scored according to the Dimeglio and Pirani score. The relationships between the two scores, the number of casts and the need for tenotomy were analysed. RESULTS Initial correction was achieved in all feet. Both Dimeglio (r = .73; p value < .0005) and Pirani scores (r = .56; p value < .000) showed good association with the number of casts. Multiple linear regression showed a high collinearity of the two scores but a more significant contribution of the Dimeglio score. Among subcomponents, hindfoot score, midfoot score, varus and muscular abnormality were independent predictors of the number of casts. Both Dimeglio and Pirani scores were significantly associated with the need for tenotomy (p value = .0000), and odds ratios and cut-off points were calculated. The receiving operator curve (ROC) analysis showed slightly better performance of the Dimeglio in comparison with the Pirani score in predicting the need for tenotomy, but the difference between the two areas under the curve (AUC) was not significant (p = .48). CONCLUSIONS A quite accurate prediction of the number of casts and the need for tenotomy can be performed in most cases. The Dimeglio score showed slightly better accuracy in predicting both steps of Ponseti treatment.

Abstract
Objective The aim of this study was to assess the role of sonographic evaluation of Talar dysplasia in predicting the outcome of standard Ponseti method in the treatment of clubfoot deformity. Methods A total 23 children (15 boys and 8 girls; mean age: 18.2 ± 5.4 days (8–32)) who underwent Ponseti treatment were included in the study. Before the treatment, maximal talus length of affected and non-affected feet were measured by US and relative talar dysplasia ratio (RTDR) was calculated. The patients were categorized 2 groups according to RTDR: group A – mild and group B – severe deformity. Pirani score was used for clinical evaluation. The groups were compared in terms of number of the applied casts, need of percutaneous tenotomy of Achilles tendon (AchT) and frequency of deformity recurrence. Results Pirani score was 4.46 for population (4.33 for group A; 4.54 for group B). Number of casts significantly differed between groups (p < 0.001) and positive correlation was found (r = 0.851, p < 0.001). AchT was performed in 56% cases for group A and in 86% cases for group B; no statistically significant difference was obtained (p = 0.162). Recurrence occurred in 2 patients belonging to group B without significant difference compared to group A (p = 0.502). Conclusion Talar dysplasia assessment appeared as a promising prognostic factor for predicting the outcome of the Ponseti technique in treatment of clubfoot deformity. Level of evidence Level IV, diagnostic study.

Abstract
PURPOSE The Pirani score is widely used in the treatment of idiopathic clubfoot. Some authors recommended to base decision for Achilles tenotomy in Ponseti method on this score (hindfoot score [HFS] > 1, once reducibility of lateral head of talus (LHT) is zero) instead of originally described indications (dorsiflexion < -10-15° once complete abduction is achieved). Yet correspondence of these indications has not been evaluated. Aim of this study was to verify whether in a cohort, where decision is based on dorsiflexion, the Pirani score corresponds to the limits suggested. Secondarily, to describe temporal variation in Pirani score along treatment, which has not been previously investigated. METHODS In a prospective study, 79 idiopathic clubfeet in 47 cases consecutively treated with Ponseti method by a single orthopaedic surgeon were evaluated at each casting session with Pirani system; score progression and scores at time of decision to perform tenotomy were determined. RESULTS HFS and its subcomponents showed minimal improvement during subsequent sessions of casting and then rapid correction with tenotomy. Medial crease resolved rapidly. Midfoot score and its remaining subcomponents corrected gradually. Total Pirani score showed initially a progressive correction and then a more abrupt improvement with tenotomy. At the time of decision to perform tenotomy, in 8 (10.1%) of 79 cases, the decision whether or not to perform tenotomy based on dorsiflexion would have been different based on the cut-offs for Pirani score suggested. CONCLUSION Using Pirani score in guiding indication for tenotomy may imply different decisions in a portion of cases, which should be considered when comparing series.

Abstract
Background: Congenital talipes equinovarus (CTEV) or clubfoot is a common pediatric congenital foot deformity that occurs 1 in 1,000 live births. Clubfoot is characterized by four types of foot deformities: hindfoot equinus; midfoot cavus; forefoot adductus; and hindfoot varus. A structured assessment method for clubfoot is essential for quantifying the initial severity of clubfoot deformity and recording the progress of clubfoot intervention. Aim: This study aims to develop a three-dimensional (3D) assessment method to evaluate the initial severity of the clubfoot and monitor the structural changes of the clubfoot after each casting intervention. In addition, this study explores the relationship between the thermophysiological changes in the clubfoot at each stage of the casting intervention and in the normal foot. Methods: In this study, a total of 10 clubfoot children who are <2 years old will be recruited. Also, the data of the unaffected feet of a total of 10 children with unilateral clubfoot will be obtained as a reference for normal feet. A Kinect 3D scanner will be used to collect the 3D images of the clubfoot and normal foot, and an Infrared thermography camera (IRT camera) will be used to collect the thermal images of the clubfoot. Three-dimensional scanning and IR imaging will be performed on the foot once a week before casting. In total, 6–8 scanning sessions will be performed for each child participant. The following parameters will be calculated as outcome measures to predict, monitor, and quantify the severity of the clubfoot: Angles cross section parameters, such as length, width, and the radial distance; distance between selected anatomical landmarks, and skin temperature of the clubfoot and normal foot. The skin temperature will be collected on selected areas (forefoot, mid foot, and hindfoot) to find out the relationship between the thermophysiological changes in the clubfoot at each stage of the casting treatment and in the normal foot. Ethics: The study has been reviewed and approved on 17 August 2016 by the Sydney Children's Hospitals Network Human Research Ethics Committee (SCHN HREC), Sydney, Australia. The Human Research Ethics Committee (HREC) registration number for this study is: HREC/16/SCHN/163.

Abstract
BACKGROUND Objective evaluation of infant with clubfoot is required as conventional imaging modality is of limited usefulness. Ultrasound shows to be a promising technique for assessing deformity and monitoring of clubfoot correction. AIM Study was done to evaluate the deformity sonographically; to assess the changes in these parameters after treatment by Ponseti method and to correlate these ultrasonographic variables with clinical Pirani score. MATERIALS AND METHODS 82 feet in 54 children were observed. Clinical assessment was done using Pirani six point system and ultrasound machine with 7.5-12MHz linear transducer was used to measure several parameters and data obtained was assessed to derive correlation between sonographic parameters and clinical system. RESULTS Medial malleolus navicular distance (MMN) measured on medial view, calcaneo-cuboid distance (CCD) and calcaneo-cuboid angle (CCA) measured on lateral view, talar length (TAL) measured on dorsal view and tibio-calcaneal distance (TCL) measured on posterior view showed statistical significance. Sonographic parameters correlated statistically with Pirani scoring system on measuring Pearson correlation coefficient. CONCLUSION Ultrasound is a relatively simple, non invasive and widely available procedure that can improve pathomorphological documentation of nonossified clubfoot and its correction. LEVEL OF EVIDENCE Level II prospective study, as per guidelines for authors.

Abstract
The Pirani and Dimeglio scoring systems both have excellent inter-observer and intra-observer reliability, but no research has been conducted to determine their inter-observer reliability and their relationship at different levels of deformity. A total of 173 idiopathic clubfoot cases were reviewed using Pirani and Dimeglio scoring systems, and the number of casts needed was also recorded. For clubfeet with a cast number equal to 2 or 7 and 8, the inter-observer reliability of the two scoring systems was poor or moderate, and there was no correlation between the two scoring systems. There was also no correlation between the Dimeglio scoring score with the number of casts for grade II or IV clubfeet. A binary regression of the number of casts on initial Pirani or Dimeglio scores showed that there was a Quadratic or Cubic relation between the scores and the cast numbers. In conclusion, in the case of mild and very severe clubfoot deformity, the interobserver reliability and its ability to predict the number of casts needed for clubfoot deformity correction was poor. A more objective evaluation system may be required.

Abstract
BACKGROUND Idiopathic clubfoot is bilateral in approximately 50% of cases and has been widely reported to affect males more frequently than females. Despite these observations, the correlation between sex and severity of the deformity has not been established. As well, the difference in severity between unilateral and bilateral clubfeet has not been extensively investigated. Therefore, the goals of the present study were to: (1) examine the relationship between sex and severity of deformity and (2) determine the relationship between laterality and severity of deformity. METHODS The families of infants with idiopathic clubfoot deformity treated at our institution were prospectively invited to participate in this institutional review board-approved study. Severity of the deformity was assessed by a single surgeon for each patient using the Dimeglio criteria at the first clinic visit. After evaluating the distributions, the correlations were quantified by nonparametric analyses. RESULTS Over 8 years, 240 infants met the inclusion criteria. There was no significant difference in the severity of deformity due to sex (P=0.61): the median Dimeglio score for males was 13 (variance 4.8) and for females, the median was 13.0 (variance of 5.1). In contrast, severity was distributed differently among unilateral versus bilateral patients. Although both unilateral and bilateral patients had a median Dimeglio score of 13, the ratio of bilateral patients was higher among those with moderate or very severe deformities compared with those with severe deformities (P<0.01). CONCLUSIONS Although idiopathic clubfoot is commonly considered to affect male patients disproportionately, this is the first study to document no difference in severity due to sex. Further, this study demonstrated that on average, bilateral patients did not have increased severity, but presented with a larger range of severity than those patients with unilateral deformity.

Abstract
UNLABELLED After the success of Dr Ponseti's method for the treatment of idiopathic clubfoot deformity, the number of patients who need soft tissue release has decreased, but the use of foot abduction orthosis is crucial for maintaining correction after this method. The lack of adherence to the orthosis regimen is reported to be a major factor for recurrence. Noncompliance with brace may be because of skin ulceration and blistering or irritability of children because of restrictiveness of the leg motion in the brace. The aim of this article is to introduce a new design of Denis Browne brace (accordion Hinge DB brace) and evaluate the results. We treated a total of 90 patients with idiopathic clubfoot (145 clubfeet) by Dr Ponseti's method and then prescribed a new design accordion to a hinge DB brace after correction of the deformity. We retrospectively reviewed the rate of complications, noncompliance, results, and effectiveness of this newly designed brace. The mean follow-up duration was 36 months (range 14-50 months). All 145 (100%) clubfeet showed complete correction after applying Dr Ponseti's method before brace prescription. Then, the accordion hinge DB brace was applied after removal of the last cast, 23 h a day for 3 months, followed by nightly use subsequently for up to 4 years. Noncompliance was encountered for 15 (10.3%) clubfeet and in 11 (7.5%) clubfeet, relapse was observed. The mean time to relapse was 14 months. Among 15 noncompliant patients, 13 were older than 2 years of age and only one relapse occurred in a patient younger than 2 years old. We did not encounter any case with skin ulceration. On the basis of the results, and compared with our previous study with a classic DB brace, a considerable reduction in noncompliance and relapse was observed. We did not encounter any case with skin ulceration. This accordion hinge DB brace reduces the rate of the complications of classic DB brace, and we strongly recommend the accordion hinge DB brace after the Ponseti method and serial casting.

Abstract
BACKGROUND The initial treatment of congenital idiopathic clubfoot (CIC) is nonoperative. Either the French physiotherapy method or the Ponseti casting method may be used. Whether either method is superior over the other remains unclear. However, the method used initially is not the only determinant of the final outcome. OBJECTIVE The primary objective was to identify determinants of the final outcome as evaluated based on the need for surgical treatment and on the Ghanem-Seringe score. HYPOTHESIS Factors associated with the final outcome can be identified. METHODS Between 2004 and 2011, 100 CICs in 79 patients were treated in two centres, 47 using the French method and 53 the Ponseti method. The Dimeglio grade was determined at baseline and the Ghanem-Seringe score at last follow-up. Surgical procedures (if any), splinting duration, and rehabilitation therapy duration were recorded. The two groups showed no statistically significant differences for Dimeglio grade distribution, time from birth to treatment initiation, or mean follow-up. RESULTS Factors significantly associated with a poor outcome by univariate analysis were use of the Ponseti method (P=0.0027), older age at last follow-up (P=3×10-4), initial Dimeglio grade (P=7×10-5), and need for surgery (P=10-5); no significant effect was found for splinting duration, rehabilitation duration, bilateral involvement, or antenatal diagnosis. By multivariate analysis, factors independently associated with a poor prognosis were older age at last follow-up, Dimeglio grade, and need for surgery. CONCLUSION This study confirms the major prognostic significance of initial severity (Dimeglio grade) on the final outcome. The data do not firmly establish that one method is superior over the other. Nevertheless, the need for percutaneous Achilles tenotomy with the Ponseti method leads us to prefer the French physiotherapy method. LEVEL OF EVIDENCE IV, retrospective study.

Abstract
Clubfoot, known as congenital talipes equinovarus, is one of the complex paediatric foot deformity with the incidence of 1 in every 1000 live births. It consists of four complex foot abnormalities such as forefoot adductus, midfoot cavus, and hindfoot varus and ankle equinus. There are a number of surgical techniques (soft tissue releases, arthrodesis) used to correct clubfoot. However currently the conservative management (manipulation, serial casting, and braces) of clubfoot is considered as the best choice and it is widely accepted among orthopaedists. Clubfoot treated with surgical techniques might suffer various complications such as soft tissues contractures, neurovascular complications, infections, and shortening of the limbs. Although conservative method is generally considered as an effective method, it is still challenging to cure clubfoot in advance stages. Also, the classification of the initial severity of clubfoot is essential to evaluate the outcome of the treatment. In this review, the aim is to review the different types of conservative method and the assessment of clubfoot severity.

Abstract
UNLABELLED Introduction The purpose of this study was to determine whether foot abduction and heel angles have any influence on resultant equinus correction and whether hindfoot dorsiflexion can be predicted based on these parameters.Material and Methods Twenty-four children with 39 unintervened idiopathic clubfeet who completed Ponseti's casting and percutaneous Achilles tenotomy with satisfactory equinus correction (≥15°) were included. Measurements included foot abduction and heel angle at the beginning of cast treatment, pre-tenotomy, and post-tenotomy along with post-tenotomy hindfoot dorsiflexion. Statistical relationships were calculated using Pearson's coefficients.Results The changes in heel angle correlated better with post-tenotomy dorsiflexion achieved than changes in foot abduction. Pre-tenotomy foot abduction or heel angle did not have any statistically significant correlation with post-tenotomy dorsiflexion. Furthermore, there was a significant relationship between post-tenotomy foot abduction and post-tenotomy dorsiflexion.Conclusions Changes in foot abduction and heel angle (from initial casting to pre-tenotomy measurement) statistically correlated to post-tenotomy hindfoot dorsiflexion achieved. Absolute degree measurements of pre-tenotomy abduction or heel valgus did not correlate with the post-tenotomy hindfoot dorsiflexion achieved. There was also significant correlation between post-tenotomy abduction and post-tenotomy hindfoot dorsiflexion. Correlation between post-tenotomy heel valgus and post-tenotomy hindfoot dorsiflexion was weak. LEVELS OF EVIDENCE Prognostic, Level II: Prospective study.

Abstract
The initial treatment of idiopathic clubfoot was mostly surgical for the 1980s/1990s. In the latter half of the 1990s, there was a surge of interest in the Ponseti method of casting after the publication of Dr. Ponseti's 30-year results. Many authors have since shown correction rates in the high 90th percentile, rendering posteromedial release surgery almost obsolete. The success of the Ponseti method has been brought internationally and extrapolated to more and more difficult cases, such as idiopathic or syndromic, primary or recurrence. This new trend will create a different subset of complications.

Abstract
Potocki-Lupski syndrome (PTLS) is a rare chromosomal microduplication syndrome resulting in multiple congenital abnormalities including developmental delays, autistic features, and certain structural anomalies, with cardiovascular being the most common. The phenotype of this contiguous gene duplication syndrome is quite variable and may include musculoskeletal abnormalities. Given the infrequency and novelty of this disorder, full phenotypic characterization of PTLS has not yet been fully elucidated. We present a case of severe bilateral clubfoot in a patient with PTLS. Diagnosis was made by array-based comparative genomic hybridization and confirmed by fluorescence in-situ hybridization. Because clubfoot was also present in an apparently unaffected brother, the presence of PTLS may have acted as a modifier of the phenotype. This report highlights the complex interaction of chromosomal and familial factors that contribute to musculoskeletal birth defects.

Abstract
This study examines inter-rater reliability between physiotherapists using the Pirani scoring system for clubfoot, and whether the addition of two scale points to give a modified five-point severity scale improves reliability. A total of 65 infant feet were assessed by two raters, with 21 different rater combinations used. The Pirani scoring system was found to be a reliable assessment tool when used by physiotherapists to score clubfoot, with a minimum of fair to good inter-rater reliability demonstrated across all clinical signs. The modified five-point scale proved significantly more reliable than the three-point scale; however, the benefit is not sufficient to warrant varying the original three-point scale.

Abstract
We report on three children with bilateral, congenital clubfoot. Four of the six clubfeet were associated with preaxial polydactyly. Five of the six clubfeet were treated without extensive surgery. A plantigrade foot was achieved, even in the three clubfeet with polydactyly, using serial casting and percutaneous Achilles tenotomy. Casting was adapted according to the existing polydactyly. One case with tibial hemimelia and a complex clubfoot deformity with preaxial tarsal polydactyly required more comprehensive surgery. A foot with good weight-bearing function was also achieved in this case following resection of the accessory medial ray, including resection of the accessory tarsal bones and posterior release. Remaining limitations in mobility were ascribed to hindfoot pathologies.

Abstract
BACKGROUND A number of grading systems for severity of clubfoot have been reported in the literature, but none are universally accepted. The aim of this study was to find the correlation between 2 of the most widely utilized classification systems (the Pirani score and the Dimeglio score) with number of Ponseti casts required to achieve initial clubfeet correction. METHODS A retrospective study of prospectively collected data was performed. All clubfeet assessed at our dedicated clubfoot clinic from January 2007 to December 2011 were included. Clubfoot severity was assessed using both the Pirani score and the Dimeglio score. The total number of casts was calculated from the first cast to the time of initiation of the foot abduction orthosis. RESULTS The mean number of Ponseti casts required to achieve initial correction was 5.8 (range, 2 to 10 casts). A low correlation (rs 0.21) was identified when the total Dimeglio score was compared with the number of casts. No correlation (rs 0.12) was identified between the Pirani score and the number of casts. CONCLUSIONS The Dimeglio and Pirani scores remain the most widely accepted clubfoot severity grading systems. However, their prognostic value remains questionable, at least in the early treatment stages. LEVEL OF EVIDENCE Prognostic study level II.

Abstract
PURPOSE The prediction of number of casts in the Ponseti method has always remained a subject of interest. We investigated the correlation of the number of casts before tenotomy with the age and initial Pirani score in Ponseti treatment of club foot. METHODS Inclusion criteria were idiopathic clubfeet corrected by Ponseti method requiring tenotomy for equinus correction in children up to ten years of age. Defaulters (noncompliance with serial casting schedule), children with postural, non idiopathic, previously surgically treated, recurrent clubfoot and clubfoot not requiring tenotomy were not included in this study. Further, children who did not require tenotomy were also excluded. ANOVA regression analysis was used for finding correlation between initial Pirani score, age in months and number of corrective casts prior to tenotomy. RESULTS There were a total of 297 children (442 feet) in the study. The average age of the child at presentation was 10.3 months and the average initial Pirani score was 4.8. The average number of corrective casts was seven per child (range, two to18). The regression analysis showed both Pirani and age had positive correlation with number of casts, although weak (r2 = 0.05-0.20). The initial Pirani scoring correlated ten times more than age (in months) to the number of casts. CONCLUSION The number of casts for correction in idiopathic clubfoot, although variable, is influenced by both initial Pirani score and age.

Abstract
The talonavicular (TN) joint and the three subtalar (ST) joints are linked anatomically and functionally. Together they form the subtalar joint complex, where movement occurs between the calcaneopedal unit (CPU) (entire foot except the talus) and the talotibiofibular unit (talus held tightly by the ankle mortise). Many are unaware of the TN joint's dual membership: it is a component of the subtalar joint complex (talocalcaneonavicular joint) and also the transverse tarsal joint (with the calcaneal-cuboid joint). The anatomy of the articulating surfaces, movement of the CPU when unloaded, shifts and changes in CPU shape with weight bearing, application to clinical tests and X-ray interpretation, and the pathophysiology applications to pes cavovarus, pes planovalgus and congenital talipes equinovarus (club foot) will be reviewed here. The CPU concept corresponds to a horizontal segmentation of the foot. This is a useful supplement to the two other segmentation methods: frontal (hindfoot, midfoot and forefoot) and sagittal (medial and lateral columns). This horizontal segmentation solves the issues with the ST joint complex, which straddles the hindfoot and midfoot, and also the issues with the dual membership of the TN joint. This concept makes it easier to understand foot deformities, better interpret the clinical and radiological signs and deduce logical treatments.

Abstract
Objective To evaluate outcomes of 229 idiopathic clubfeet (ICF) treated using the Ponseti method, from 2001 to 2011, comparing two groups with different follow-ups. Method 155 patients (229 ICF) were treated separated in two groups: Group I: 72 patients (109 ICF – 47.6%) with a follow up of 62 to 128 months (mean of 85). Group II: 83 patients (120 ICF – 52.4%) with a follow up of 4 to 57 months (mean of 33.5). We have considered satisfactory outcomes for cases which correction of all deformed components, without surgery. Results Mean age for the initial assessment was 5.4 months in Group I and 3.2 in Group II. Satisfactory outcomes were obtained in 85.4% in Group I and 97.5% in Group II. Mean cast placements were 9.5 in Group I and 7 in Group II. 67% were submitted to percutaneous Achilles tenotomy in Group I and 65% in Group II. Deformity relapses, when using abducted braces, occurred in 41 (37.6%) feet from Group I; 11 were treated surgically. In Group II, 17 feet relapsed (14.1%); three of them were submitted to surgery. Conclusion The method was successful in both groups, in low number of complications. The results were statistically superior in Group II when deformity correction, cast placements, relapses and surgery indication.

Abstract
The Ponseti method has become the gold standard of care for the treatment of congenital club foot. Despite numerous articles in MEDLINE reporting results from around the globe there are still crucial details of the Ponseti method which seem to be less commonly known or considered. The Ponseti method is not only a detailed method of manipulation and casting but also of preventing and treating relapse. Recommendations on how to correct complex club foot have resulted in an almost 100 % initial correction rate. The foot abduction brace is crucial for preventing relapse and is still a challenge for families and sometimes doctors alike. Experience and knowledge on how to support the parents, how to set and apply the brace in the best possible way and how to solve problems that can be encountered during the bracing period are essential to ensure compliance. Regular follow-up visits are necessary to be able to detect early signs of recurrence and prevent full relapse by enforcing abduction bracing, recasting or performing tibialis anterior tendon transfer. Recent midterm outcome studies have shown that by following the Ponseti treatment regime in all aspects it is possible to prevent open joint surgery in almost all cases. The body of literature of the last decade has evaluated many steps and aspects of the Ponseti method and gives valuable answers to questions encountered in daily practice. This review of the current literature and recommendations on the different aspects of the Ponseti method aims to promote understanding of the treatment regime and its' details.

Abstract
Clubfoot (talipes equinovarus) is a three-dimensional deformity of unknown etiology. Treatment aims at correction to obtain a functional, plantigrade pain-free foot. The "French" functional method involves specialized physiotherapists. Daily manipulation is associated to immobilization by adhesive bandages and pads. There are basically three approaches: the Saint-Vincent-de-Paul, the Robert-Debré and the Montpellier method. In the Ponseti method, on the other hand, the reduction phase using weekly casts usually ends with percutaneous tenotomy of the Achilles tendon to correct the equinus. Twenty-four hour then nighttime splinting in abduction is then maintained for a period of 3 to 4 years. Recurrence, mainly due to non-compliance with splinting, is usually managed by cast and/or anterior tibialis transfer. The good long-term results, with tolerance of some anatomical imperfections, in contrast with the poor results of extensive surgical release, have led to a change in clubfoot management, in favor of such minimally invasive attitudes. The functional and the Ponseti methods reported similar medium term results, but on scores that were not strictly comparable. A comparative clinical and 3D gait analysis with short follow-up found no real benefit with the increasingly frequent association of Achilles lengthening to the functional method (95% to 100% initial correction). Some authors actually suggest combining the functional and Ponseti techniques. The Ponseti method seems to have a slight advantage in severe clubfoot; if it is not properly performed, however, the risk of failure or recurrence may be greater. "Health economics" may prove decisive in the choice of therapy after cost-benefit study of each of these treatments.

Abstract
BACKGROUND The Ponseti method of idiopathic clubfoot treatment involves a series of weekly casts, a percutaneous Achilles tenotomy if needed, followed by wearing a foot abduction orthosis (FAO). Gross motor development of children with idiopathic clubfoot has not been examined. The purposes of this study were to determine the ages of achievement of gross motor milestones in children with clubfoot treated with Ponseti method and to compare those ages with historical normative developmental data. METHODS In this prospective study, 51 children with idiopathic clubfoot who had their first cast applied when ≤90 days old, were full-term with no other orthopaedic conditions or previous clubfoot treatment, and were compliant with wearing FAO were enrolled. Parents were interviewed repeatedly to acquire the ages of achievement of 8 gross motor milestones. RESULTS Fifteen children were excluded for reasons such as noncompliance with FAO, and not returning for follow-up. Thirty-six children, mean age of 15.2 days at first casting, achieved rolling prone to supine at a mean age of 5.1 months, rolling supine to prone at 5.1 months, sitting without support at 6.6 months, crawling on stomach at 7.1 months, crawling on hands and knees at 8.6 months, pull-to-stand at 9.0 months, cruising at 10.2 months, and ambulating independently at 13.9 months. When compared with previously published values for unaffected children, the mean ages of achievement for 6 of 8 milestones were significantly greater (P<0.05) for the children with clubfoot. The preambulatory milestones were achieved from 0.7 to 1.5 months later and independent ambulation up to 2.2 months later. Fifty percent of children with clubfoot were ambulating at 13.8 months; 90% at 17.7 months. CONCLUSIONS Minimal delays in gross motor milestone achievement were found in children with idiopathic clubfoot treated with the Ponseti method. Delays were, at most, 1.5 months, except for independent ambulation, which was approximately 2 months. These findings should enable pediatric clinicians to alleviate the concerns of parents of children with idiopathic clubfoot regarding gross motor milestone achievement. LEVEL OF EVIDENCE Therapeutic Level II.

Abstract
BACKGROUND Relapse of clubfoot deformity following correction by Ponseti technique is not uncommon. The relapsed feet progress from flexible to rigid if left untreated and can become as severe as the initial deformity. No definitive classification exists to assess a relapsed clubfoot. Some authors have used the Pirani score to rate the relapse while others have used descriptive terms. The purpose of this study is to analyze the relapse pattern in clubfeet that have undergone treatment with the Ponseti method and propose a simple classification for relapsed clubfeet. MATERIALS AND METHODS Ninety-one children (164 feet) with idiopathic clubfeet who underwent treatment with Ponseti technique presented with relapse of the deformity. There were 68 boys and 23 girls. Mean age at presentation for casting was 10.71 days (range 7-22 days). Seventy three children (146 feet, 80%) had bilateral involvement and 18 (20%) had unilateral clubfeet. The mean Pirani Score was 5.6 and 5.5 in bilateral and unilateral groups respectively. Percutaneous heel cord tenotomy was done in 65 children (130 feet, 89%) in the bilateral group and in 12 children (66%) with unilateral clubfoot. RESULTS Five relapse patterns were identified at a mean followup of 4.5 years (range 3-5 years) which forms the basis of this study. These relapse patterns were classified as: Grade IA: decrease in ankle dorsiflexion from15 degrees to neutral, Grade IB: dynamic forefoot adduction or supination, Grade IIA - rigid equinus, Grade IIB - rigid adduction of forefoot/midfoot complex and Grade III: combination of two or more deformities: Fixed equinus, varus and forefoot adduction. In the bilateral group, 21 children (38 feet, 28%) had Grade IA relapse. Twenty four children (46 feet, 34%) had dynamic intoeing (Grade IB) on walking. Thirteen children (22 feet, 16%) had true ankle equinus of varying degress (Grade IIA); eight children (13 feet, 9.7%) had fixed adduction deformity of the forefoot (Grade IIB) and seven children (14 feet, 10.7%) had two or more fixed deformities. In the unilateral group seven cases (38%) had reduced dorsiflexion (Grade IA), six (33%) had dynamic adduction (Grade IB), two (11%) had fixed equinus and adduction respectively (Grade IIA and IIB) and one (5%) child had fixed equinus and adduction deformity (Grade III). The relapses were treated by full time splint application, re-casting, tibialis anterior transfer, posterior release, corrective lateral closing wedge osteotomy and a comprehensive subtalar release. Splint compliance was compromised in both groups. CONCLUSION Relapse pattern in clubfeet can be broadly classified into three distinct subsets. Early identification of relapses and early intervention will prevent major soft tissue surgery. A universal language of relapse pattern will allow comparison of results of intervention.
