Ponseti method compared with soft-tissue release for the management of clubfoot: A meta-analysis study

AIM: To compare the functional outcomes of patients who underwent open surgery vs Ponseti method for the management of idiopathic clubfoot and to determine whether correlations exist between functional outcome and radiographic measurements.METHODS: A meta-analysis of the literature was conducted for studies concerning primary treatment of patients with idiopathic clubfoot. We searched PubMed Medline, EMBASE, and the Cochrane Library databases from January 1950 to October 2011. Meta-analyses were performed on outcomes from 12 studies. Pooled means, SDs, and sample sizes were either identified in the results or calculated based on the results of each study.RESULTS: Overall, 835 treated idiopathic clubfeet in 516 patients were reviewed. The average follow-up was 15.7 years. Patients managed with Ponseti method did have a higher rate of excellent or good outcome than patients treated with open surgery (0.76 and 0.62, respectively), but not quite to the point of statistical significance (Q = 3.73, P = 0.053). Age at surgery was not correlated with the functional outcome for the surgically treated patients (r = -0.32, P = 0.68). A larger anteroposterior talocalcaneal angle was correlated with a higher rate of excellent or good outcomes (r = 0.80, P = 0.006). There were no other significant correlations between the functional and radiographic outcomes.CONCLUSION: The Ponseti method should be considered the initial treatment of idiopathic clubfeet, and open surgery should be reserved for clubfeet that cannot be completely corrected.     

Clinico-sonographical evaluation of idiopathic clubfoot and its correction by Ponseti method — A prospective study

BackgroundObjective 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.AimStudy 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 methods82 feet in 54 children were observed. Clinical assessment was done using Pirani six point system and ultrasound machine with 7.5–12 MHz linear transducer was used to measure several parameters and data obtained was assessed to derive correlation between sonographic parameters and clinical system.ResultsMedial 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.ConclusionUltrasound is a relatively simple, non invasive and widely available procedure that can improve pathomorphological documentation of nonossified clubfoot and its correction.Level of evidenceLevel II prospective study, as per guidelines for authors.     

Accelerated Ponseti method: First experiences in a more convenient technique for patients with severe idiopathic club feet

BackgroundCongenital Idiopathic Talipes Equinovarus (CTEV), or clubfoot, is a complex deformity that involves pathological anatomy in the foot with ankle equinus, hindfoot varus, midfoot cavus and forefoot adductus [1]. Universal agreement is established about Ponseti technique as the initial management for this deformity. This preliminary study aims to investigate the possibility of having a braceable foot through a proposed accelerated Ponseti method by which, manipulations, 5 castings and Achilles tendon tenotomy are implemented in a week.MethodsThis study included 11 patients with 16severe congenital idiopathic clubfeet treated by an accelerated Ponseti method. The method involves manipulation of the deformed foot, and 1st casting in one day, with the 2nd, 3rd, 4th, 5th castings in the 4th, 5th, 6th, 7th day post-manipulation. After the 4th cast removal, Achilles tenotomy was performed with subsequent three-week casting for all patients. Nonparametric tests were used for comparing the Pirani scores before starting the treatment and after removal of final cast.ResultsFive patients had bilateral club foot deformity. Average age at treatment was 54.8 days (range 8–150 days). All patients, who had severe congenital idiopathic club feet with a Pirani score of 6, underwent the accelerated Ponseti technique. After removal of the three-week cast, the scores median was 0.59, (range 0–1.5), indicating a correction of the deformity and having braceable feet in all patients without experiencing any short-term complication.ConclusionsThe first step accelerated Pnoseti technique was found to be safe and effective for initial correction of severe idiopathic clubfoot deformity in children below three months of age , though it is an initial study that needs more studies with more follow up data.     

Percutaneous tendo-achilles lengthening with a large-gauge needle: A modification of the ponseti technique for correction of idiopathic clubfoot

The Ponseti technique has become standard for the treatment of congenital idiopathic clubfoot. Treatment includes serial manipulations and casting, accompanied by percutaneous tenotomy of the Achilles tendon. In this article, the authors describe a modification in the Achilles tenotomy technique by using a large-gauge hypodermic needle in the outpatient setting.

Evaluation of the treatment of idiopathic clubfoot by using the Ponseti method

The initial treatment of congenital idiopathic talipes equinovarus (clubfoot) is most often nonsurgical. However, surgical treatment in the form of posteromedial release is often undertaken after failure of conservative measures. The prevalence of both immediate and long-term complications in surgically treated clubfeet has cultivated a renewed interest in nonsurgical treatment. The Ponseti method for treating clubfoot has seen a revived interest among those caring for infantile clubfeet. We report on our first 34 infants (57 clubfeet) treated by using the techniques and principles described by Ponseti. Using a standard scoring system, 54 of 57 clubfeet were successfully corrected without requiring posteromedial release. Only 2 patients (3 clubfeet) required extensive surgical correction. There were 6 relapses. In all recurrent cases, there was a lack of compliance with the straight-last shoe and foot abduction bar regimen. Based on this level of initial success, we believe that posteromedial release is no longer necessary for the majority of cases of congenital clubfeet.     

Multidisciplinary management of clubfeet using the Ponseti method in a district general hospital setting

Purpose  Idiopathic congenital talipes equinovarus (CTEV) is a relatively common complex deformity of the foot that can be successfully managed by the Ponseti method. The purpose of this study was to see if the latter can be effectively administered by non-medical specialists outside a specialist or teaching hospital setting. Method  Retrospective review of 24 children (39 feet) with idiopathic congenital talipes equinovarus managed by a physiotherapist-led service in a district general hospital. Results  The median Pirani score at presentation was 4.5 (mean 4.2, range 1.5–6). The median Pirani score for feet requiring tenotomy was 6 (4.5–6), whereas feet not requiring tenotomy had a median Pirani score of 2.5 (1.5–5). A total of 18 feet (46%) underwent an Achilles tenotomy. Foot correction was achieved with an average of 3.4 (2–6) cast changes in the non-tenotomy group, and an average of 7.5 (5–13) in the tenotomy group. Successful initial correction of the deformity was achieved in 37 (95%) of the feet studied. One patient (2 feet, 5%) failed local conservative management, requiring tertiary referral. Two children (2 feet) have relapsed, requiring further serial casting. No children required open surgical release. Follow-up was for a mean of 31 months (17–50). Conclusions  Early results suggest that a combined consultant/physiotherapist-delivered Ponseti service can be effectively and successfully administered in a district general hospital.     

Radiography and sonography of clubfoot: A comparative study

Background:

Congenital talipes equinovarus is a common foot deformity afflicting children with reported incidence varying from 0.9/1000 to 7/1000 in various populations. The success reported with Ponseti method when started at an early age requires an imaging modality to quantitate the deformity. Sonography being a radiation free, easily available non-invasive imaging has been investigated for this purpose. Various studies have described the sonographic anatomy of normal neonatal foot and clubfoot and correlated the degree of severity with trends in sonographic measurements. However, none of these studies have correlated clinical, radiographic and sonographic parameters of all the component deformities in clubfoot. The present study aims to compare the radiographic and sonographic parameters in various grades of clubfoot.

Materials and Methods:

Thirty-one children with unilateral clubfoot were examined clinically and graded according to the Demeglio system of classification of clubfoot severity. Antero-posterior (AP) and lateral radiographs of both normal and affected feet were obtained in maximum correction and AP talo-calcaneal (T-C), AP talo-first metatarsal (TMT) and lateral T-C angles were measured. Sonographic examination was done in medial, lateral, dorsal and posterior projections of both feet in static neutral position and after Ponseti manouever in the position of maximum correctability in dynamic sonography. Normal foot was taken as control in all cases. The sonographic parameters measured were as follows : Medial malleolar- navicular distance (MMN) and medial soft tissue thickness (STT) on medial projection, calcaneo-cuboid (C-C) distance, calcaneo-cuboid (C-C) angle and maximum length of calcaneus on lateral projection, length of talus on dorsal projection; and tibiocalcaneal (T-C) distance, posterior soft tissue thickness and length of tendoachilles on posterior projection. Also, medial displacement of navicular relative to talus, mobility of talonavicular joint (medial view); reducibility of C-C mal alignment (lateral view); talonavicular relation with respect to dorsal/ ventral displacement of navicular (dorsal view) and reduction of talus within the ankle mortise (posterior view) were subjectively assessed while performing dynamic sonography. Various radiographic and sonographic parameters were correlated with clinical grades.

Results:

MMN distance and STT measured on medial view, C-C distance and C-C angle measured on lateral view and tibiocalcaneal distance measured on posterior view showed statistically significant difference between cases and controls. A significant correlation was evident between sonographic parameters and clinical grades of relevant components of clubfoot. All radiographic angles except AP T-C angle were significantly different between cases and controls. However, they did not show correlation with clinical degree of severity.

Conclusion:

All radiographic angles except AP T-C angle and sonographic parameters varied significantly between cases and controls. However, radiographic parameters did not correlate well with clubfoot severity. In contrast, sonography not only assessed all components of clubfoot comprehensively but also the sonographic parameters correlated well with the severity of these components. Thus, we conclude that sonography is a superior, radiation free imaging modality for clubfoot.     

Ponseti method in the treatment of post-operative relapsed idiopathic clubfoot after posteromedial release. A short term functional study

BackgroundRelapsed clubfeet deformity after surgical treatment by posteromedial release are frequently encountered in pediatric orthopedic practice and further revision surgery may be needed. As surgery adds more fibrosis and scaring, complication may be devastating and treatment is challenging. Ponseti method, the gold standard technique for treatment of clubfoot may be of a value in the management of postoperative relapses.Aim of the studyDetermine the effectiveness of Ponseti casting Method in treatment of relapsed idiopathic clubfoot in children after being treated with surgical posteromedial release.Materials and methodsProspective interventional study of 17 patients (25 feet) presented with a relapsed idiopathic clubfoot deformity after previous surgical posteromedial release. The patients were reviewed using Pirani and Dimeglio score. Ponseti method was done to obtain supple, flexible foot rather than a fully corrected foot, the residual deformity were treated by, heel cord lengthening or tenotomy, tibialis anterior transfer, follow up was for a minimum of 12 months.Result17 Patients (25 feet) their age ranging from 1 to 10 years were evaluated and treated. Casts were applied until the only deformities remaining were either hindfoot equinus and/or dynamic supination.22 feet required a heel cord procedure for equinus and 13 required tibialis anterior transfer for dynamic supination. The follow up (average 56.1 months) was for a minimum of one year. 4 feet had persistent heel varus deformity which required Calcaneal osteotomy later. Three feet didn’t need more casting and 2 feet were resistant cases that required further Ilizarov procedure, 4 needed lateral arch shortening and other 4 needed posterior capsulotomy. Improvement in the Pirani and Dimeglio scores was highly statistically significant.ConclusionPonseti method for treatment of relapsed clubfeet after a previous posteromedial soft tissue surgical release is an effective, non invasive, with excellent results.     

Use of the Ponseti method for recurrent clubfoot following posteromedial release

Background:

A child with recurrent or incompletely corrected clubfoot after previous extensive soft tissue release is treated frequently with revision surgery. This leads to further scarring, pain and limitations in range of motion. We have utilized the Ponseti method of manipulation and casting and when indicated, tibialis anterior tendon transfer, instead of revision surgery for these cases.

Materials and Methods:

A retrospective review of all children treated since 2002 (n = 11) at our institution for recurrent or incompletely corrected clubfoot after previous extensive soft tissue release was done. Clinical and operative records were reviewed to determine procedure performed. Ponseti manipulation and casting were done until the clubfoot deformity was passively corrected. Based on the residual equinus and dynamic deformity, heel cord lengthening or tenotomy and tibialis anterior transfer were then done. Clinical outcomes regarding pain, function and activity were reviewed.

Results:

Eleven children (17 feet) with ages ranging from 1.1 to 8.4 years were treated with this protocol. All were correctable with the Ponseti method with one to eight casts. Casts were applied until the only deformities remaining were either or both hindfoot equinus and dynamic supination. Nine feet required a heel cord procedure for equinus and 15 required tibialis anterior transfer for dynamic supination. Seven children have follow-up greater than one year (average 27.1 months) and have had excellent results. Two patients had persistent hindfoot valgus which required hemiepiphyseodesis of the distal medial tibia.

Conclusion:

The Ponseti method, followed by tibialis anterior transfer and/or heel cord procedure when indicated, can be successfully used to correct recurrent clubfoot deformity in children treated with previous extensive soft tissue release. Early follow-up has shown correction without revision surgery. This treatment protocol prevents complications of stiffness, pain and difficulty in ambulating associated with multiple soft tissue releases for clubfeet.     

Correlation of scores with number of Ponseti casts required for clubfoot correction in the older child

BackgroundWe examined the correlation between initial Pirani and Dimeglio scores and their individual components to the number of casts for older clubfoot children.MethodsTwenty 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.ResultsAverage 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.ConclusionsThe 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.     

The impact of the Ponseti treatment method on parents and caregivers of children with clubfoot: a comparison of two urban populations in Europe and Africa

Purpose

With the Ponseti treatment method established as the gold standard, children with clubfeet face a prolonged treatment regime that might impact on their families. We aimed to determine how Ponseti treatment influences the lives of parents and caregivers and what coping strategies they use. Secondarily, we aimed to identify any potential differences between two urban referral centres for clubfoot.

Methods

A total of 115 parents of children affected with idiopathic clubfoot were recruited and included in two groups: one from the United Kingdom (UK) and the other from South Africa (SA). The participants completed the following three instruments: the Impact on Family Scale (IOFS), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Brief COPE.

Results

During the bracing phase, the IOFS showed a trend towards lower scores when compared to the casting phase for both cohorts (p = 0.247 and p = 0.434, respectively). The SA population scored higher than the UK in the MSPSS in both casting (p = 0.002) and bracing phases (p = 0.004) and used coping strategies at a significantly higher level when compared to the UK population (p < 0.05) in both treatment phases.

Conclusion

This is the first study to show that Ponseti treatment for clubfoot causes an impact on family function. In SA, perceived social support is higher and coping strategies are used more often than in the UK to deal with the stressful circumstances of treatment.

     

Management issues of congenital talipes equinovarus in the neonatal intensive care unit: A systematic review

BackgroundThe Ponseti method is the standard of care for managing idiopathic congenital talipes equinovarus (clubfoot) in the outpatient setting, but there are no clinical guidelines for inpatient treatment. Children in the neonatal intensive care unit (NICU) with clubfoot often delay treatment initiation due to medical reasons.MethodsWe systematically reviewed literature related to the treatment of clubfoot in the NICU, non-idiopathic clubfoot, and older infants, as well as barriers to care.ResultsIn a mixed NICU population of syndromic and idiopathic clubfoot, the Ponseti method has good functional outcomes with minimal interference with medical management. The Ponseti method has good functional outcomes with reduced need for extensive surgical procedures in non-idiopathic clubfoot and idiopathic clubfoot with delayed presentation (under one year of age).ConclusionsIt is possible to begin Ponseti treatment in the NICU without compromising medical management. It is not clear if this confers an advantage over waiting for outpatient casting.     

Comparative evaluation and analysis of outcomes in non-idiopathic and idiopathic clubfeet with Ponseti method at a tertiary care centre of a developing country

BackgroundIdiopathic clubfoot (congenital talipes equinovarus, CTEV) is being managed worldwide by Ponseti method with high success rates, while for non-idiopathic clubfoot surgical interventions is being widely used with variable results. This study evaluated the effectiveness of Ponseti method in non-idiopathic clubfoot and compared the results with idiopathic clubfoot.MethodsThe paper evaluated the epidemiological incidence and demographic profile of non-idiopathic clubfoot in a tertiary centre of developing country. A total of 108 subjects with 85 having idiopathic (group I;125 feet) and 23 having non-idiopathic variety (group II;34 feet) were managed with Ponseti method and were followed for a mean duration of 38.33 (12–62) and 36.27 months (12–58) in group I and II respectively. The most common associations were meningomyelocele (MMC/spina bifida,5), arthrogryposis multiplex congenita (AMC,4), developmental dysplasia of hip (DDH,3) and Down’s syndrome and amniotic band syndrome (2 each).ResultsPrimary correction was achieved in both the groups in 98% and 87% in group I and II respectively, while recurrences of at least one deformity was observed in 11 (9%) and 12 (40%) feet in group I and II respectively. Favourable outcomes were noticed in 22 (65%) feet in non-idiopathic group and 12 feet (35%) underwent extensive soft tissue release as compared to 3 feet (2.4%) in idiopathic variety.ConclusionDeformities improved significantly in non-idiopathic clubfeet with Ponseti methods although complete correction was not possible. Extensive surgical interventions were reduced in up to 35% feet in non-idiopathic variety and hence, it is recommended as primary treatment for all variety of clubfeet, irrespective of their etiology.     

Mid-term results of a physiotherapist-led Ponseti service for the management of non-idiopathic and idiopathic clubfoot

BackgroundThe Ponseti method is the preferred treatment for idiopathic clubfoot. Although popularised by orthopaedic surgeons it has expanded to physiotherapists and other health practitioners. This study reviews the results of a physiotherapist-led Ponseti service for idiopathic and non-idiopathic clubfeet and compares these results with those reported by other groups.MethodA prospective cohort of clubfeet (2005–2012) with a minimum 2-year follow-up after correction was reviewed. Physiotherapists treated 91 children—41 patients (69 feet) had non-idiopathic deformities and 50 children (77 feet) were idiopathic. Objective outcomes were evaluated and compared to results from other groups managing similar patient cohorts.ResultsThe mean follow-up was 4.6 years (range 2–8.3 years) for both groups. The non-idiopathic group required a median of 7 casts to correct the clubfoot deformity with an 83 % tenotomy rate compared to a median of 5 casts for the idiopathic group with a 63 % tenotomy rate. Initial correction was achieved in 96 % of non-idiopathic feet and in 100 % of idiopathic feet. Recurrence requiring additional treatment was higher in the non-idiopathic group with 40 % of patients (36 % of feet) sustaining a relapse as opposed to 8 % (6 % feet) in the idiopathic group. Surgery was required in 26 % of relapsed non-idiopathic feet and 6 % of idiopathic.ConclusionsAlthough Ponseti treatment was not as successful in non-idiopathic feet as in idiopathic feet, deformity correction was achieved and maintained in the mid-term for the majority of feet. These results compare favourably to other specialist orthopaedic-based services for Ponseti management of non-idiopathic clubfeet.

Expanded Age Indication for Ponseti Method for Correction of Congenital Idiopathic Talipes Equinovarus: A Systematic Review

The deformity known as congenital idiopathic talipes equinovarus (CTEV) is probably the most common (1 to 2 in 1000 live births) congenital orthopedic condition requiring intensive treatment. With the perception that the treatment of idiopathic CTEV by extensive soft tissue release is often complicated by stiffness, recurrence, and the need for additional procedures, the minimally invasive Ponseti method has been accepted as the first line of treatment, which has achieved excellent results globally. The Ponseti method has achieved excellent results in children with idiopathic CTEV aged ≤2 years. However, the upper age limit for the Ponseti treatment has not yet been defined. We reviewed the published data to determine the efficacy of the Ponseti method in older children with neglected CTEV.     

Clinical,radiological, pedobarographic,and quality of life outcomes of the Ponseti treatment for clubfoot: a prospective study

BackgroundTalipes equinovarus, also known as clubfoot, is a congenital anomaly that affects one newborn per 1000 live births. Its standard treatment strategy is Ponseti casting management. This study aims to report the long-term outcomes of the Ponseti treatment in Iran.MethodsA prospective cohort study was enrolled to evaluate clinical outcomes, radiological results, pedobarographic measurements, and quality of life after the Ponseti treatment in patients with clubfoot who were followed for at least five years.ResultsIn this study, 25 clubfeet of 18 patients were included. Significant reductions in Pirani, Dimeglio, and CAP scores, improved ankle dorsiflexion, and acceptable pedobarographic indices were observed in this study. From the radiological evaluation indices, the calcaneal pitch and lateral talus-first metatarsal angles were significantly reduced. After five years of treatment, patients’ quality of life was favorable, which was better in females. This study showed that the results of the Ponseti treatment remained acceptable after five years.ConclusionsThe Ponseti management for clubfoot in the long term appears to maintain significant improvements. However, the recurrence rate – albeit without disruption to daily activities – cannot be ignored.     

The ultrasonography evaluation of talar dysplasia as a potential prognostic factor for predicting the course and outcomes of clubfoot deformity treatment using Ponseti technique

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.
