Case report of application of Ponseti method in treatment of neglected congenital talipes equinovarus in boy with DiGeorge syndrome who was 4 years and 9 months of age at the beginning of the treatment. Foot was classified as very severe, scored 4.5 points according to Pirani and 15 points according to DiMeglio classification. After 9 casts set according to Ponseti protocol good correction of all components was achieved accept for the equinus deformity. Achilles lengthening procedure was done, but there was necessity to perform posterior release to achieve good dorsiflexion. Finally, goals of treatment were achieved: the foot is flexible, well shaped, pain free, ready for weight-bearing and use of commercial shoes. At current stage of treatment the foot scores 0.5 points according Pirani and 4 points according to DiMeglio classifications.
We present a systematic review of the results of the Ponseti method of management for congenital talipes equinovarus (CTEV). Our aims were to assess the method, the effects of modifications to the original method, and compare it with other similar methods of treatment. We found 308 relevant citations in the English literature up to 31 May 2010, of which 74 full-text articles met our inclusion criteria. Our results showed that the Ponseti method provides excellent results with an initial correction rate of around 90% in idiopathic feet. Non-compliance with bracing is the most common cause of relapse. The current best practice for the treatment of CTEV is the original Ponseti method, with minimal adjustments being hyperabduction of the foot in the final cast and the need for longer-term bracing up to four years. Larger comparative studies will be required if other methods are to be recommended.
The purpose of this study was to evaluate the early results of the Ponseti method in reducing extensive corrective surgery rates for congenital idiopathic clubfoot in patients treated in Children’s Orthopaedic Clinic and Rehabilitation Department Medical University of Lublin between the years 2007–2011. Thirty-five patients with 47 idiopathic clubfeet were followed prospectively while being managed with the Ponseti method. Clubfoot severity was graded with use of the Dimeglio system. The initial correction was achieved, and early results were measured by using Pirani scoring method.
The optimal management of idiopathic clubfoot has changed over three decades. Recently there has been an enthusiastic embracing of the Ponseti technique with a move away from the traditional stretch and strap technique. The purpose of this 14-year comparative prospective longitudinal study was to directly assess the differences in results between these two treatment methods. Over the period of this study there were 52,514 births in the local population and all newborns with clubfoot were referred directly to the paediatric orthopaedic surgeon. Patient demographics, the Harrold & Walker Classification, and associated risk factors for clubfoot were collected prospectively and analyzed. If conservative treatment failed to correct the deformity adequately, a radical subtalar release (RSR) was undertaken (the primary outcome measure of the study). There were 114 feet (80 patients) : 64 feet treated ‘traditionally’ and 50 feet with the Ponseti technique. Idiopathic clubfoot was present in 76.25% of patients. Mean time to RSR was 33.3 and 44.1 weeks for the traditional and Ponseti groups respectively. In the traditional group 65.6% (CI : 53.4 to 76.1%) of feet underwent RSR surgery compared to 25.5% (CI : 15.8 to 38.3%) in the Ponseti group. When idiopathic clubfoot alone was analysed, these rates reduce to 56.5% (CI : 42.3 to 69.8%) and 15.8% (CI : 7.4 to 30.4%) respectively. The Relative Risk of requiring RSR in traditional compared to Ponseti groups was 2.58 (CI : 1.59 to 4.19) for all patients and 3.58 (CI : 1.65 to 7.78) for idiopathic clubfoot. Introduction of the Ponseti technique into our institution significantly reduced the need for RSR in fixed clubfoot.
Tibiofibular torsion was measured by computed tomography in three series of patients affected by congenital clubfoot who were treated with different protocols. The normal leg of unilateral deformities served as the control. For the bilateral cases, only the right side was included in the study. The angle between the bicondylar axis of the tibia and the bimalleolar axis was the index of tibiofibular torsion. There were 34 clubfeet in the first series, treated with a posteromedial release, and 40 clubfeet in the second series, treated with a modified Ponseti method, whereas the third series included 16 clubfeet, treated with the original Ponseti method. All 90 clubfeet were graded at birth as group 3 according to the Manes classification. No patient had previous treatment. The patients of the first and the second series were followed up to maturity, whereas the patients of the third series were followed up to a maximum of 11 years of age. In the congenital clubfoot, the tibia and the fibula were externally rotated, in comparison with the normal leg; in fact, the average value of the angle of tibiofibular torsion was 32.2° in the first series, 23.9° in the second series, and 21.1° in the third series. In the normal tibiae, the average value of the angle of tibiofibular torsion was 21.4°. The difference between the first series and the normal controls was statistically significant, as was the difference between the first one and the other two series. The value of the tibiofibular torsion angle seems to be related to the manipulation technique used to treat clubfoot: when the manipulation does not allow a progressive eversion of the talus underneath the calcaneus, the external tibial torsion increases. At follow-up, an intoeing gait was present in seven treated clubfeet of the first series. In all of them except one, the highest value of the external tibial torsion angle was observed, with a low value of the Kite's angle and/or residual forefoot adduction. In the treated congenital clubfoot, persistent intoeing is not related to the angle of tibial torsion but rather to the amount of correction of calcaneal inversion and residual forefoot adduction.

The purpose of the present study was to evaluate the efficacy of multiple tenotomies performed after application of the Ponseti method in reducing the tendency for recurrence in the severe rigid idiopathic clubfoot and limiting the need for application of the hyperabduction brace in the prewalking age. From November 2002 to December 2004, 30 severe (Pirani >5), rigid (nonresilient), idiopathic clubfeet in newly born infants aged 2 to 24 days were treated by the Ponseti method of weekly manipulations and castings until achieving full correction, apart from equinus. With the patient under general anesthesia, through 2 small incisions (2 cm), tenotomy of the Achilles tendon, tibialis posterior, and flexor digitorum longus was performed, together with posterior capsulotomy of the ankle to achieve >30° dorsiflexion in 26 feet. An above the knee plaster cast in extreme dorsiflexion and 70° hyperabduction was applied for 6 to 8 weeks. This was followed by a hyperabduction brace on a full-time basis (23 hours daily) for an additional 6 months. A satisfactory result was achieved after a follow-up period of 2 to 5 (mean 3.8) years. The Pirani score on initial presentation was 5 to 6 and on the final visit was 0 to 0.25, with 10° to 20° passive dorsiflexion of the ankle in those who underwent posterior capsulotomy compared with 5° to 10° in the 4 patients who had not. The number of manipulations needed before tenotomy was 5 to 7 (mean 5.9), reflecting the rigidity of the studied feet. Active plantarflexion to almost normal power was regained at 18 to 30 months of age. A relapse developed in only 1 foot that failed to respond to manipulation and casting. It required posteromedial release and tibialis anterior transfer at 2 years of age. The proposed minimally invasive procedure of open multiple tenotomies and posterior capsulotomy of the ankle is safe and effective. If performed in newly born infants with severe rigid clubfeet followed by strict application of the hyperabduction brace on a full time basis for 6 months, it will ensure full correction of the deformity. Thus, the brace can be discarded before the infant reaches walking age, with no tendency for relapse.
The French method, also called the functional physical therapy method, is a combination of physiotherapy, splinting and surgery à la carte. The French functional physical therapy method consists of daily manipulations of the newborn's clubfoot by a specialized physical therapist, stimulation of the muscles around the foot and temporary immobilization of the foot with elastic and nonelastic adhesive taping. Physiotherapy is optimized by early triceps surae lengthening. Sequences of plaster can also be used. If conservative treatment is no longer effective, surgery should be considered. Mini-invasive surgery is a complementary procedure to nonoperative treatment (surgery 'à la carte'). The French method reduces but does not eliminate the need for mini-invasive surgical procedures. Equinus is the most difficult deformity to treat; posterior release is sometimes necessary in a severe foot. Very severe feet (stiff-stiff; score, 16-20) are still a challenge. However, regular manipulations and splinting improve foot morphology and stiffness, and, ultimately, make surgery easier and less extensive. From the French method to the Ponseti method, the Hybrid method or the 'the third way', combining the advantages of both methods, is the future. The primary reason for relapses is the inability of families to maintain the correction initially achieved. The aim of this work is to provide an overview of the French functional physical therapy method and to help understand how it has evolved over time.
Relapse after tibialis anterior tendon transfer in idiopathic clubfoot treated by the ponseti method.
Masrouha KZ, Morcuende JA. J Pediatr Orthop. 2012 Jan;32(1):81-4.
Quote:
BACKGROUND:
The Ponseti method for clubfoot correction has demonstrated excellent results. However, relapses are common and continue to be the most important problem facing clubfoot practitioners. Relapses usually require repeated casting and/or surgical intervention with tibialis anterior tendon transfer (TATT). However, recent data on relapses suggest that performing a successful TATT may not be a definitive cure as there may be other processes, such as neuromuscular deficits, that may result in subsequent relapses.
METHODS:
The authors reviewed 66 patients (102 clubfeet) treated by TATT for clubfoot relapses after successful initial treatment by the Ponseti method. Ten patients (15 clubfeet) experienced a subsequent relapse. Demographic, clinical, and treatment data was recorded.
RESULTS:
These patients had a tendency toward a greater number of casts at initial treatment (P=0.14) and they underwent relapse surgery earlier than those who did not relapse after TATT (P=0.05). Two of these patients had a neuromyopathy, diagnosed by muscle biopsy. The treatment of post-TATT relapse included casting (6 patients), ankle foot orthotic (4 patients), physical therapy (2 patients), or bracing (1 patient). One patient was treated by osteotomies of the cuboid and medial cuneiform and 1 patient had a peroneus longus to peroneus brevis tendon transfer.
CONCLUSIONS:
Performing a TATT may not be the definitive treatment for clubfoot relapses as neuromuscular deficits may be involved. In addition, these patients may be at an increased risk of relapse due to the earlier age at which TATT was performed. When there is a high index of suspicion, prompt diagnosis with muscle biopsy is warranted.
Mid-term results of Ponseti method for the treatment of congenital idiopathic clubfoot--(a study of 67 clubfeet with mean five year follow-up).

Quote:
BACKGROUND:
Long-term success reports by Dr. Ponseti with the Ponseti method in the treatment of congenital idiopathic clubfoot have led to a renewed interest in this method among pediatric orthopedists. The purpose of this study is to evaluate mid-term effectiveness of Ponseti method for the treatment of congenital idiopathic clubfoot.
MATERIAL AND METHODS:
A total of 49 patients (67 clubfeet) were treated by Ponseti method by single orthopedic surgeon during the period of October 03 to July 07 and were studied prospectively up to July 10 (mean follow up period 5 years, minimum follow-up period of 3 years). Age at the initiation of the treatment, gender, bilaterality, severity of the initial clubfoot deformity measured by Pirani Severity Score System, total numbers of Ponseti casts before the tenotomy, details of tenotomy, compliance with brace and CTEV shoes were examined. Passive range of movements and look of club foot are evaluated with mean 5 years follow-up.
RESULTS:
We followed the functional Ponseti Scoring System and got good to excellent results in 44 patients--89.79% (58 clubfeet--86.56%) at mean five year of follow up. Parents of 32 patients (65.30%) accept the look of the clubfoot nearly normal and parents of 12 patients (24.49%) accept the look of clubfoot as normal. Of the 49 patients who responded to initial Ponseti casting, 14 patients--28.57% (19 clubfeet--28.35%) had relapse at varying age; out of which 9 patients--64.29% (10 clubfeet--52.63%) were corrected by Ponseti casting method, while 5 patients--35.71% (9 clubfeet--47.37%) were resistant to Ponseti method. Poor compliance with the Denis Browne splint was thought to be the main cause of failure in these patients.
CONCLUSION:
Ponseti method is a safe and satisfactory treatment for congenital idiopathic clubfoot with mid- term effectiveness.

BACKGROUND:
The Ponseti method has become increasingly popular in the treatment of congenital talipes equinovarus (CTEV). Current methods of assessment focus on clinical, functional and radiological outcomes which are subjective and often difficult to repeat. However, integration of biomechanical evaluation can provide objective and quantifiable analysis. This study aims to evaluate the treatment outcome of CTEV patients on the basis of long-term clinical, functional and biomechanical assessment.
METHODS:
Following treatment, five children with CTEV were reviewed annually for the period 2008-2010. Clinical and functional outcomes were graded using parental questionnaires and clinical examination. Biomechanical parameters were evaluated using digital foot pressure studies.
RESULTS:
The study group recorded good clinical and functional outcomes. However, biomechanical studies have been able to identify subtle abnormalities that would be unapparent otherwise on clinical examination.
CONCLUSIONS:
It is recommended that biomechanical assessment be integrated into the overall evaluation of the outcome of CTEV after treatment
BACKGROUND:
The most common congenital orthopaedic condition requiring treatment is clubfoot. The Ponseti method, which has improved the recurrence rate, is at present the most attractive method of treatment in the north of America. The purpose of this study was to evaluate the outcome of this method in an Iranian population and look for characteristics that may affect the treatment process.
METHODS:
A total of 78 patients (129 feet) were treated by precisely adhering to the technique originally introduced by Ponseti. Relapse was defined as any return of each of 4 clubfoot components according to the Dimeglio-Bensahel system. The mean follow-up period was 24.7 months and relapse was analyzed with respect to severity of primary disorder, number of casts, compliance with postcorrection bracing and stretching exercise, and educational level of parents.
RESULTS:
At the end of the follow-up, 24 (18.6%) clubfeet experienced relapse as defined. The mean time to relapse was 13.7 months, 30 feet had brace noncompliance, and stretching was not done for 35 feet. Significant association was detected between recurrence and severity of clubfoot, number of casts for complete correction, and bracing and stretching exercise noncompliance.
CONCLUSIONS:
The Ponseti method is a successful treatment protocol for idiopathic clubfoot. Its success rate will increase with use of abduction orthosis after complete correction and also by performing regular stretching exercises.
Congenital clubfoot is one of the most common congenital skeletal defects. Its aetiology remains unclear. Due to its high incidence and social consequences, the therapy of congenital clubfoot presents an important medical issue. Non-surgical treatment methods are preferred. Many publications confirmed the efficacy of the Ponseti method. The aim of this study was to present early results of congenital clubfoot treatment using the Ponseti method in a one-year follow-up. The therapy protocol was in accordance with guidelines presented by the inventor. The necessity of surgical treatment was a criterion for negative treatment outcome. One hundred and sixteen feet of 92 children were analysed. A Dimeglio-Bensahel classification was used for the evaluation of the defect advance. Seventy-one feet (61.2%) were assessed as grade II, 43 feet as grade III (37.1%) and 2 feet as grade IV deformation. No patients with grade I deformation were included into the study. A positive treatment outcome was observed for 96 feet (82.7%), whereas a negative result for the remaining 20 feet (17.3%). Our results are therefore not consistent with the literature data. It could have resulted from the too precipitate qualification for surgery by the physician and problems with compliance. The Ponseti method is an effective and less straining treatment modality of the congenital clubfoot. In most cases it allows for avoiding extensive surgery and associated complications. A necessity of wearing an orthosis and a risk treatment failure, if not worn systematically, should be emphasised. A longer follow-up period is required for complete result analysis.

PURPOSE:
The success of the Ponseti method for treating idiopathic clubfoot deformity is dependent on the casting techniques and the adherence of the patient to the foot abduction brace protocol. Newly developed brace designs claim to be more comfortable, to be easier to use and to prevent dislodgement of the foot from the brace, making them more efficient and improving patient compliance. They are, however, more costly, and, therefore, accessible to fewer patients. We compared the compliance and treatment outcome using two brace designs, the traditional simple brace of pre-walking shoes attached to a Dennis Browne (DB) bar and the new sophisticated Mitchell brace.
METHODS:
We compared the functional outcome and compliance with the post-corrective bracing protocol of 38 children with idiopathic clubfoot treated in our institution using two brace designs. Twenty-one chose the DB brace and 17 chose the Mitchell brace.
RESULTS:
There was no difference in the compliance rate or in the final clinical and radiological outcomes of the two groups after a minimum of 2 years of follow-up. A positive correlation was found between the Pirani score at the beginning of treatment and the final functional score for both groups. Both groups were satisfied with the selected brace. Both groups were equally compliant with the brace protocol.
CONCLUSION:
We conclude that new and more expensive brace designs do not necessarily provide better clinical results. Fully corrected foot and a strong family-treating team partnership are crucial to adherence with the brace protocol.

Quote:
The Ponseti method has been reported to have successful results in clubfoot patients less than 6 months of age but the literature on its efficacy in older clubfoot patients still remains sparse. In our study, we prospectively evaluated 55 clubfeet (37 patients) to determine clinically whether the Ponseti method is effective in the management of clubfoot in older children between the age of 12 and 36 months (mean: 24.8 months). All the patients belonged to moderate or severe grades of deformity as per the Pirani scoring. Painless, supple, plantigrade and cosmetically acceptable feet were achieved in 49 clubfeet. Seven patients (seven feet) developed recurrence of adduction, varus and equinus deformity whereas three patients (five feet) developed isolated recurrence of equinus deformity. These seven patients responded to repeat treatment and obtained satisfactory outcome. Four of these seven patients underwent tibialis anterior transfer to third cuneiform for dynamic supination. Three patients, those developed isolated recurrence of equinus deformity, underwent repeat tenotomy. One foot achieved satisfactory amount of dorsiflexion, three feet underwent tendoachilles lengthening whereas another foot underwent posterior release to obtain satisfactory dorsiflexion. Six to 12 numbers of casts (mean: 10) were required to obtain correction of clubfoot deformities. Mean period of immobilization in a cast was 13.9 weeks (10-15 weeks). We found that the Ponseti method is effective in children between the age of 12 and 36 months.
Treatment Results of Late-relapsing Idiopathic Clubfoot Previously Treated With the Ponseti Method.
McKay SD, Dolan LA, Morcuende JA. Pediatr Orthop. 2012 Jun;32(4):406-11.
Quote:
BACKGROUND:
Idiopathic clubfoot has a stubborn tendency for relapse, with most relapses happening within the first few years. However, a few patients relapse later, adding to the complexity of management. This study investigates the treatment results of relapsing clubfoot deformity after age 4.
METHODS:
Thirty-nine patients (60 feet) met the inclusion criteria. Age at initial treatment, previous treatment, number of casts and tenotomies, length of bracewear, and relapse presentation were recorded. Treatment of late relapse followed 1 of the 5 courses: (1) observation only (4 feet); (2) bracing (26 feet); (3) casting followed by bracing (7 feet); (4) casting followed by tibialis anterior tendon transfer (TATT) with or without open tendo Achilles lengthening (TAL) (8 feet); or (5) primary TATT±TAL (15 feet). Of the 37 feet treated initially with observation, bracing, or casting, 33 went on to have TATT (89%). Multiple other concurrent procedures were performed according to the specific deformities. These included plantar fasciotomy (6 feet), extensor hallicus longus recession (5 feet), limited posterior release 5 feet, and others (3 feet). Five feet underwent revision surgery after TATT, 2 of which ended in triple arthrodeses.
RESULTS:
Average age at final follow-up was 23.3 years (range, 8.5 to 50.6 y). Ninety percent of patients wore regular shoes, 41% had pain with activities, but only 18% were limited in function by their feet. Average ankle dorsiflexion was 6 degrees (range, -15 to 25 degrees). Mild residual deformities were noted in 55% of feet.
CONCLUSIONS:
This challenging group of patients with apparently persistent deforming biology achieves acceptable results with individualized evaluation and treatment of their foot deformities.
Achilles tenotomy as an office procedure: safety and efficacy as part of the ponseti serial casting protocol for clubfoot.
Lebel E, Karasik M, Bernstein-Weyel M, Mishukov Y, Peyser A. J Pediatr Orthop. 2012 Jun;32(4):412-5.
Quote:
BACKGROUND:
Ponseti demonstrated the correction of clubfoot in infants using manipulation followed by the application of well-molded long-leg plaster casts. Percutaneous Achilles tenotomy was recommended to correct residual equinus contracture in approximately 80% of cases. In the current study, we evaluated the safety of this practice for the treatment of clubfoot when performed as an "office procedure" without sedation or general anesthesia during the final stage of the serial casting protocol.
PATIENTS AND METHODS:
We retrospectively collected data regarding babies who underwent serial manipulation and casting according to the Ponseti protocol for the treatment of clubfoot. All babies managed in the outpatient clinic between 2006 and 2010 were included. Tenotomy was indicated when the forefoot was completely corrected and if the hind-foot showed rigid equinus. Tenotomy was performed by a single scalpel stab in the outpatient clinic, using topical and local anesthesia (without general anesthesia or sedation). The cast was then applied and kept on for 3 weeks. Babies were discharged home after 1 hour of supervision. Surgical reports regarding Achilles tenotomy were reviewed, and data were collected from postoperative notes. We specifically looked for perioperative complications, recovery unit notes, and hospital readmission.
RESULTS:
Fifty-six babies (83 feet) were included in the current study. There were 40 males and 16 females, and 27 of them had bilateral clubfoot. Three babies (0.5%) had complex (syndrome-related) clubfoot; familial risk was known in 6 (11%) babies. Forty-one (73%) babies were indicated for Achilles tenotomy. Tenotomy was performed after an average of 5 casts (range, 3 to 9). No adverse events were related to local anesthesia and/or the procedure itself, and there was no delay in discharge in any of the operated babies. One baby was evaluated in the emergency room 3 days after the procedure because of (unfounded) parental concern of swelling inside the cast. All other babies had an uneventful course. Retenotomy was performed in 7 babies (12 feet); 2 of them (4 feet) had complex clubfoot. All of these babies (ie, their parents), except 1, had moderate to poor compliance with the treatment protocol.
CONCLUSIONS:
Tenotomy as an office procedure using topical and local anesthesia is a safe procedure. It does not incur a substantial rate of readmission to the emergency room, either because of parental concern or because of actual complications. The need for retenotomy is related to a low compliance with the treatment protoco

The Ponseti method applied to treating idiopathic club foot consists in placing successive corrective casts, possibly an Achilles tendon tenotomy, then derotation braces, a method that has proven its efficacy. This study compared 221 cases of club foot treated with this method between 2002 and 2007 divided into two groups, based on whether or not Achilles tendon tenotomy was performed. Assessment was both clinical and sonographic. We observed clear improvement of the results in the group that underwent Achilles tendon tenotomy and a significant difference in the rate of secondary surgery. The sonographic evaluation also showed improvement of the morphological results. We now systematically propose Achilles tendon tenotomy however severe club foot may be.

Background and purpose
In 2002-2003, several hospitals in Norway introduced the Ponseti method for treating clubfoot. The present multicenter study was conducted to evaluate the initial results of this method, and to compare them to the good results reported in the literature.
Patients and methods 116 children with 162 congenital idiopathic clubfeet who were born between 2004 and 2006 were treated with the Ponseti method at 8 hospitals in Norway. All children were prospectively registered at birth, and 116 feet were assessed according to Pirani before treatment was started. 63% used a standard bilateral foot abduction brace, and 32% used a unilateral above-the-knee brace. One of the authors examined all feet at a mean age of 4 years. At follow-up, all feet were assessed by Pirani's scoring system, and range of motion of the foot and ankle was measured.
Results At follow-up, 77% of the feet had a Pirani score of 0.5 or better, good dorsiflexion and external rotation, and no forefoot adduction. An Achilles tenotomy had been performed in 79% of the feet. Compliance to any brace was good; only 7% were defined as non-compliant. Extensive soft tissue release had been performed in 3% of the feet. We found no statistically significant differences between the two braces, except a tendency of better Pirani score in the group using the bilateral foot abduction brace, and a tendency of better compliance in patients using the unilateral brace. Better Pirani scores were found in children who were treated at the largest hospitals. Interpretation After introducing the Ponseti method in Norway, the clinical outcome was good and in accordance with the reports from single centers. Only 5 feet needed extensive surgery during the first 4 years of life.
The purpose of the present study was to evaluate the efficacy of multiple tenotomies performed after application of the Ponseti method in reducing the tendency for recurrence in the severe rigid idiopathic clubfoot and limiting the need for application of the hyperabduction brace in the prewalking age. From November 2002 to December 2004, 30 severe (Pirani >5), rigid (nonresilient), idiopathic clubfeet in newly born infants aged 2 to 24 days were treated by the Ponseti method of weekly manipulations and castings until achieving full correction, apart from equinus. With the patient under general anesthesia, through 2 small incisions (2 cm), tenotomy of the Achilles tendon, tibialis posterior, and flexor digitorum longus was performed, together with posterior capsulotomy of the ankle to achieve >30° dorsiflexion in 26 feet. An above the knee plaster cast in extreme dorsiflexion and 70° hyperabduction was applied for 6 to 8 weeks. This was followed by a hyperabduction brace on a full-time basis (23 hours daily) for an additional 6 months. A satisfactory result was achieved after a follow-up period of 2 to 5 (mean 3.8) years. The Pirani score on initial presentation was 5 to 6 and on the final visit was 0 to 0.25, with 10° to 20° passive dorsiflexion of the ankle in those who underwent posterior capsulotomy compared with 5° to 10° in the 4 patients who had not. The number of manipulations needed before tenotomy was 5 to 7 (mean 5.9), reflecting the rigidity of the studied feet. Active plantarflexion to almost normal power was regained at 18 to 30 months of age. A relapse developed in only 1 foot that failed to respond to manipulation and casting. It required posteromedial release and tibialis anterior transfer at 2 years of age. The proposed minimally invasive procedure of open multiple tenotomies and posterior capsulotomy of the ankle is safe and effective. If performed in newly born infants with severe rigid clubfeet followed by strict application of the hyperabduction brace on a full time basis for 6 months, it will ensure full correction of the deformity. Thus, the brace can be discarded before the infant reaches walking age, with no tendency for relapse.
Background The optimal management of idiopathic clubfoot has changed over three decades. Recently there has been an enthusiastic embracing of the Ponseti technique. The purpose of this 14-year comparative prospective longitudinal study was to directly assess the differences in results between these two treatment methods.
Methods Over the period of this study there were 52,514 births in the local population and all newborns with clubfoot were referred directly to the Pediatric Orthopedic Surgeon. Patient demographics, the Harrold & Walker Classification, and associated risk factors for clubfoot were collected prospectively and analyzed. If conservative treatment failed to correct the deformity adequately, a radical subtalar release (RSR) was undertaken (the primary outcome measure of the study).
Results There were 114 feet (80 patients): 64 feet treated ‘traditionally’ and 50 feet with the Ponseti technique. Idiopathic clubfoot was present in 76.25% of patients. Mean time to RSR was 33.3 and 44.1 weeks for the traditional and Ponseti groups respectively. In the traditional group 65.6% (CI: 53.4 to 76.1%) of feet underwent RSR surgery compared to 25.5% (CI: 15.8 to 38.3%) in the Ponseti group. When idiopathic clubfoot alone was analysed, these rates reduce to 56.5% (CI: 42.3 to 69.8%) and 15.8% (CI: 7.4 to 30.4%) respectively. The Relative Risk of requiring RSR in traditional compared to Ponseti groups was 2.58 (CI: 1.59 to 4.19) for all patients and 3.58 (CI: 1.65 to 7.78) for idiopathic clubfoot.
Conclusions Introduction of the Ponseti technique into our institution significantly reduced the need for RSR in fixed clubfoot.
Introduction The Ponseti regime was introduced in Swansea in 2003 for the treatment of congenital talipes equinovarus (CTEV). The aim of this retrospective cohort study was to compare children treated with this regime with a historical group treated traditionally before then.
Materials and Methods Sixty children (89 feet) were treated with the Ponseti regime between 2003 and 2010. Their notes were compared with notes from 12 children (21 feet) treated between 1995 and 2002. Clinic attendance for serial manipulation and immobilisation (strap/cast) was compared using a two-tailed Mann Whitney U test. Major release surgery was compared using a two-tailed Fisher's Exact test.
Results Children in the historical cohort presented when they were 0–174 days old (median 1 day). They attended 3–35 times (median 22) for serial manipulation and strapping/ plasters. Major release surgery was undertaken on 14 feet (66.7%) when the children were 6–39 months old (median 9 months); 7 had revision surgery. The Ponseti cohort presented when they were 0–73 days old (median 10 days) and attended outpatients 2–19 times (median 7) for serial manipulation and casting. An Achilles tenotomy was undertaken in 54 feet (60.7%) when the children were 45–184 days old (median 71 days) and major release surgery in 17 feet (19.1%) when the children were 10–66 months old (median 21 months). Four children had revision surgery.
Discussion There is a significant reduction in outpatient attendances (Ua = 1313, p = <0.0001) for serial manipulation and reduced rate of release surgery (p = 4.56 × 10−5) since the implementation of the Ponseti regime. The rate of revision surgery in both groups was not significant (p = 0.15), although these samples were small.
Conclusion The Ponseti regime is an effective initial treatment for infants with CTEV compared with traditional treatment. It has decreased the number of clinic attendances and the rate of major release surgery.

Background
Ponseti management usually requires Achilles tenotomy during the final stage of serial casting. However, we lack a good understanding of the sequential tendon healing process after tenotomy in the Ponseti bracing protocol. The purpose of this study was to clarify the ultrasonographic process of tendon healing in the gap for up to two years after Ponseti-type Achilles tenotomy in patients with clubfeet.
Methods
We conducted an ultrasonographic study to clarify the sequential changes in gap healing for up to two years after tenotomy. The subjects were 23 patients with 33 clubfeet. Achilles tenotomy was performed at mean 10.4 (8–16) weeks after birth. Dynamic and static ultrasonography was performed before tenotomy and at 1, 2, 3, 4, 6, 8, and 12 weeks as well as at 4, 6, 12, 18, and 24 months after tenotomy.
Results
Continuity and gliding were noted within four weeks. The united portion continued to thicken for up to three months after tenotomy. Starting from the fourth month, the healed portion began to lose its thickness, and this process continued into the sixth month. At one year, the thickness of the tendon did not differ much from that of the tendon on the opposing foot. In cases where patients had clubfoot on both feet and underwent simultaneous tenotomies, measurement of the tendons could not be accurately compared. At two years after tenotomy, slight irregularity of the internal structure persisted when compared with the unaffected foot. In addition, clinical and X-ray findings were evaluated simultaneously, and no recurrence was confirmed.
Conclusions
To our knowledge, our results are the first to describe the process of gap healing in the tendon after tenotomy up to and beyond two years, as recommended in the Ponseti bracing protocol.

BACKGROUND:
Clubfoot deformity is one of the most common congenital musculoskeletal deformities and occurs in newborns with different neuromuscular diseases. To date the Ponseti method is the gold standard for the treatment of idiopathic clubfeet but not for non-idiopathic clubfeet which are associated with neuromuscular diseases. The results of the treatment for congenital idiopathic and non-idiopathic clubfeet according to Ponseti performed in our department since 2004 were compared concerning results and relapse surgery with particular reference to the compliance of the parents concerning the use of an abduction splint.
PATIENTS AND METHODS:
A total of 101 children (28 female and 73 male) with 159 clubfeet were treated with the Ponseti method and included in this prospective non-randomized cohort study. Of these children 27 with 48 affected feet suffered from neuromuscular diseases which are associated with clubfoot deformity, such as myelomeningocele (n=4), arthrogryposis (n=9) and various other syndromes (n=14). The degree of the deformity was evaluated with the Pirani score initially, after casting and at follow-up. Parents were asked at follow-up to state subjectively how compliant they were with the abduction splint treatment. The necessity of surgical treatment of relapses was recorded. Statistical analysis was performed applying χ(2) and Kruskal-Wallis tests for the comparison of idiopathic and non-idiopathic clubfeet.
RESULTS:
The average period of follow-up was 36 month (range 6-75 months) and non-idiopathic clubfeet were initially significantly more severely deformed according to the Pirani-score (p=0.013). Treatment of non-idiopathic clubfeet was started significantly later than that of idiopathic clubfeet (p=0.003) and took significantly longer (p <0.001). A correlation between the initiation of casting and the duration of casting was not found (p=0.399). At the end of the casting period no significant differences were found between correction of idiopathic and non-idiopathic clubfeet with respect to the Pirani score (p=0.8). The mean score after casting was 0.1 in both groups. At mid-term follow-up the score increased in both groups but stayed below 0.5 with non-idiopathic clubfeet showing a significantly higher score than idiopathic clubfeet (p=0.014). Relapse surgery was necessary in 11% of the patients. No significant difference in the revision rate was found between the two groups (p=0.331) and peritalar release was not necessary in either group. The rate of revisions correlated with the compliance concerning the use of the abduction splint (p <0.001). Only 61% of the parents stated that they adhered strictly to the abduction splint treatment recommendations with no significant difference between the groups (p=0.398).
CONCLUSION:
This study shows good initial results after Ponseti treatment for idiopathic as well as non-idiopathic clubfeet. Based on the good functional results all clubfeet should initially be treated with the Ponseti method regardless of the etiology.
Introduction It has been postulated that a mild clubfoot does better than a severe clubfoot no matter what treatment course is taken. There have been previous efforts to classify clubfoot. For units worldwide that use the Ponseti Method of clubfoot management, the Pirani scoring system is widely used. This scoring system has previously been shown to predict the number of plasters required to gain correction. Our study aimed to investigate whether the Pirani score gave an indication of longer-term outcome using tibialis anterior tendon transfer as an endpoint.
Methods A prospectively collated database was used to identify all patients treated in the Ponseti clinic at the Royal Manchester Children's Hospital between 2002 and 2005 with idiopathic clubfoot who had not received any treatment prior to their referral. Rate of tibialis tendon transfer as well as the patient's presenting Pirani score were noted. Feet were grouped for analytical purposes into a mild clubfoot (Pirani score <4) and a severe clubfoot (Pirani score 4) category depending on initial examination. Clinic records were reviewed retrospectively to identify patients who were poorly compliant at wearing boots and bars and were categorised into having “good” or “bad” compliance with orthosis use.
Results 132 feet in 94 children were included in the study. 30 (23%) tibialis tendon transfers were performed at a mean of 4.2 years (range 2.3–5.5 years). Children with severe clubfoot had a significantly higher rate of tendon transfer compared with those with mild clubfoot (28% vs. 6%; p=0.0001). 81% of patients were classified as being “good” boot wearers. Tibialis tendon transfer rates in those who were poorly compliant with boot usage were significantly higher compared with those with good compliance (52% vs. 16%; p=0.0003). There was a significantly higher tendon transfer rate in those with severe disease and poor compliance compared with good compliance (69% vs. 20%; p=0.0002). There was no association between boot compliance and tendon transfer rates in those with mild disease.
Conclusion This study shows that late recurrences, requiring tibialis anterior tendon transfer, are associated with severity of disease at presentation and compliance with use of orthoses. Tendon transfer rates are higher for those with severe disease. We have confirmed previous reports that compliance with orthotic use is associated with recurrence. However, the novel findings regarding recurrence rates in mild clubfeet may have implications regarding usage of orthoses in the management of mild idiopathic clubfeet after initial manipulation using the Ponseti method.
