Aims. This study aims to define a set of core outcomes (COS) to allow consistent reporting in order to compare results and assist in treatment decisions for idiopathic clubfoot. Methods. A list of outcomes will be obtained in a three-stage process from the literature and from key stakeholders (patients, parents, surgeons, and healthcare professionals). Important outcomes for patients and parents will be collected from a group of children with idiopathic clubfoot and their parents through questionnaires and interviews. The outcomes identified during this process will be combined with the list of outcomes previously obtained from a systematic review, with each outcome assigned to one of the five core areas defined by the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT). This stage will be followed by a two round Delphi survey aimed at key stakeholders in the management of idiopathic clubfoot. The final outcomes list obtained will then be discussed in a consensus meeting of representative key stakeholders. Conclusion. The inconsistency in outcomes reporting in studies investigating idiopathic clubfoot has made it difficult to define the success rate of treatments and to compare findings between studies. The development of a COS seeks to define a minimum standard set of outcomes to collect in all future clinical trials for this condition, to facilitate comparisons between studies and to aid decisions in treatment.

Purpose: Congenital idiopathic clubfoot is the most common musculoskeletal birth defect developing during the fetal period, but with no known etiology. MYH 2, 3, 7, and 8 are expressed embryonically or perinatally, the period during which congenital idiopathic clubfoot develops; are all components of Type II muscle, which is consistently decreased in clubfoot patients; and are associated with several muscle contracture syndromes that have associated clubfoot deformities. In this study, we hypothesized that mutations in embryonic and perinatal myosin genes could be associated with congenital idiopathic clubfoot. Methods: We screened the exons, splice sites, and predicted promoters of 24 bilateral congenital idiopathic clubfoot patients and 24 matched controls in MYH 1, 2, 3, and 8 via sequence-based analysis, and screened an additional 76 patients in each discovered SNP. Results: While many SNPs were found, none proved to be significantly associated with the phenotype of congenital idiopathic clubfoot. Also, no known mutations that cause distal arthrogryposis syndromes were found in the congenital idiopathic clubfoot patients. Conclusion: These findings demonstrate that congenital idiopathic clubfoot has a different pathophysiology than the clubfoot seen in distal arthrogryposis syndromes, and defects in myosin are most likely not directly responsible for the development of congenital clubfoot. Given the complexity of early myogenesis, many regulatory candidate genes remain that could cause defects in the hypaxial musculature that is invariably observed in congenital idiopathic clubfoot. Significance: This study further differentiates congenital idiopathic clubfoot as distinct from other complex genetic syndromes that can present with similar deformities, and thus facilitates further research to improve the clinical diagnosis and treatment of congenital idiopathic clubfoot

We report the effect of introducing a dedicated Ponseti service on the five-year treatment outcomes of children with idiopathic clubfoot. Between 2002 and 2004, 100 feet (66 children; 50 boys and 16 girls) were treated in a general paediatric orthopaedic clinic. Of these, 96 feet (96%) responded to initial casting, 85 requiring a tenotomy of the tendo-Achillis. Recurrent deformity occurred in 38 feet and was successfully treated in 22 by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior, The remaining 16 required an extensive surgical release. . Between 2005 and 2006, 72 feet (53 children; 33 boys and 20 girls) were treated in a dedicated multidisciplinary Ponseti clinic. All responded to initial casting: 60 feet (83.3%) required a tenotomy of the tendo-Achillis. Recurrent deformity developed in 14, 11 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior. The other three required an extensive surgical release. . Statistical analysis showed that children treated in the dedicated Ponseti clinic had a lower rate of recurrence (p = 0.068) and a lower rate of surgical release (p = 0.01) than those treated in the general clinic. This study shows that a dedicated Ponseti clinic, run by a well-trained multidisciplinary team, can improve the outcome of idiopathic clubfoot deformity.

The purpose of the present study is to evaluate the early results of the Ponseti method when used for the treatment of idiopathic clubfoot among the population of the island of Crete. Fourteen consecutive infants (twenty-one feet) with idiopathic clubfoot deformity were managed with the Ponseti method and were retrospectively reviewed at a minimum of six months. The severity of the foot deformity was classified according to the grading system of Pirani et al. The number of casts required to achieve correction was compared with published data for the treatment of idiopathic clubfoot. Recurrent clubfoot deformities or complications during treatment were recorded. Initial correction was achieved with a mean of 5.2 casts. Tenotomy and Dennis-Browne braces followed the cast applications. One foot had a relapse which was then treated by a repeat tenotomy at the age of 8 months. Two children abandoned the protocol because the parents could not comply with bracing. No extensive surgery is needed so far and all feet are flexible and pain free. X-rays when taken showed the talo-calac-neal angle within normal limits. We support the use of the Ponseti method for the treatment of idiopathic clubfoot, since it can deliver flexible physiological feet, in the outpatient environment, thus avoiding the consequences of extensive open surgery

Ponseti method has become the most common and validated initial non-operative and/or minimally invasive treatment modality of idiopathic clubfoot regardless of the severity of the deformity worldwide. Despite hundreds of publications in the literature favoring Ponseti method, the data about secondary procedures performed in the follow-up period of clubfoot and their incidence remains sparse and given as small details in the articles. The objective of this study was to analyse our incidence of secondary procedures performed in the midterm followup period of idiopathic clubfoot patients treated with Ponseti method and review of the relevant literature. For this purpose 86 feet of 60 patients with idiopathic clubfoot who were treated with original Ponseti method were enrolled in this retrospective case control study. Unilateral ankle foot orthosis (AFO) was used rather than standart bar-connected foot abduction orthosis varying from 12 months to 25 months in the follow-up period and 74 of 86 (86%) feet required percutaneous achilles tenotomy. The average age of initial cast treatment was 12.64 days (range 1 to 102 days). The mean follow-up time was 71 months (range 19 to 153 months). Thirty seven feet of 24 patients recieved secondary procedures (43%) consisting of; supramalleolary derotational osteotomy (SMDO) (1 patient/2 feet), complete subtalar release (3 patients/5 feet), medial opening lateral closing osteotomy (double osteotomy) (2 patients/3 feet), double osteotomy with transfer of tibialis anterior tendon (TTAT) (2 patients/3 feet), partial subtalar release (PSTR) (3 patients/5 feet), PSTR with SDO (1 patient/1 foot), posterior release (PR) with repeated achillotomy (1 patient/2 feet), TTAT (6 patients/10 feet), TTAT with PR (2 patients/2 feet), TTAT with Vulpius procedure (1 patient/1 foot) and TTAT with SMDO (2 patients/3 feet) respectively. The amount of percutaneous achilles tenotomy (86%) in our study correlated with the literature which ranged from 80 to 90 %. The transfer of tibialis anterior tendon continued to be the most performed secondary procedure both in our study (51%) and in the literature, but the amount of total secondary procedures in our study (43%) was determined to be higher than the literature data varying from 7 to 27 percent which may be due to unilateral AFO application after Ponseti method for idiopathic clubfoot deformity in our study

The Ponseti method is the gold standard treatment for clubfoot. It begins in early infancy with weekly serial casting for up to 3 months. Globally, a commonly reported barrier to accessing clubfoot treatment is increased distance patients must travel for intervention. This study aims to evaluate the impact of the distance traveled by families to the hospital on the treatment course and outcomes for idiopathic clubfoot. No prior studies in Canada have examined this potential barrier. This is a retrospective cohort study of patients managed at a single urban tertiary care center for idiopathic clubfoot deformity. All patients were enrolled in the Pediatric Clubfoot Research Registry between 2003 and April 2021. Inclusion criteria consisted of patients presenting at after percutaneous Achilles tenotomy. Postal codes were used to determine distance from patients’ home address to the hospital. Patients were divided into three groups based on distance traveled to hospital: those living within the city, within the Greater Metro Area (GMA) and outside of the GMA (non-GMA). The primary outcome evaluated was occurrence of deformity relapse and secondary outcomes included need for surgery, treatment interruptions/missed appointments, and complications with bracing or casting. A total of 320 patients met inclusion criteria. Of these, 32.8% lived in the city, 41% in the GMA and 26% outside of the GMA. The average travel distance to the treatment centre in each group was 13.3km, 49.5km and 264km, respectively. Over 22% of patients travelled over 100km, with the furthest patient travelling 831km. The average age of presentation was 0.91 months for patients living in the city, 1.15 months for those within the GMA and 1.33 months for patients outside of the GMA. The mean number of total casts applied was similar with 7.1, 7.8 and 7.3 casts in the city, GMA and non-GMA groups, respectively. At least one two or more-week gap was identified between serial casting appointments in 49% of patients outside the GMA, compared to 27% (GMA) and 24% (city). Relapse occurred in at least one foot in 40% of non-GMA patients, versus 27% (GMA) and 24% (city), with a mean age at first relapse of 50.3 months in non-GMA patients, 42.4 months in GMA and 35.7 months in city-dwelling patients. 12% of the non-GMA group, 6.8% of the GMA group and 5.7% of the city group underwent surgery, with a mean age at time of initial surgery of 79 months, 67 months and 76 months, respectively. Complications, such as pressure sores, casts slips and soiled casts, occurred in 35% (non-GMA), 32% (GMA) and 24% (city) of patients. These findings suggest that greater travel distance for clubfoot management is associated with more missed appointments, increased risk of relapse and treatment complications. Distance to a treatment center is a modifiable barrier. Improving access to clubfoot care by establishing clinics in more remote communities may improve clinical outcomes and significantly decrease the burdens of travel on patients and families

Aim. 10 years after the introduction of the Ponseti casting regimen as standard treatment for idiopathic clubfoot at Alder Hey Children's Hospital, we reviewed the mid-term outcomes of the initial 2-year cohort (treated from 2002–2004). Method. 100 feet were treated in 66 patients. 61 of the 100 feet have been prospectively reviewed on an annual/ bi-annual basis since successful correction, with outcomes of the remaining feet obtained by retrospective analysis. Results. 96 feet responded to initial casting; of these, 31 had a recurrence within the first 2 years (16 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior, the remaining 15 requiring extensive soft tissue release). 12 feet developed recurrence after 2 years (9 of whom were successfully treated with transfer of tibialis anterior tendon and 3 of whom required extensive soft tissue release) Mean dorsiflexion at average follow-up of 9 years is 15 degrees (95% CI 12.96 to 17.04) and mean abduction 41 degrees. (95%CI 37.65 to 45.07). Conclusion. The Ponseti regimen is a successful treatment option for the management of idiopathic clubfoot. The majority of recurrences occur in the first two years and so close follow-up should be undertaken during this period. The importance of strict compliance with boots and bars must be emphasised to parents at this treatment stage. These mid-term outcomes have highlighted that, although fewer recurrences occur after the first two years, it is difficult to predict which feet might recur; consequently, we recommend following children up in an annual/bi-annual fashion until their skeletal maturity

Purpose: The aim of this study is to analyze objectively pathoanatomical changes of clubfoot treated with Ponseti method. Introduction: In the treatment of clubfoot, regardless of the grade and severity of the disease, first conservative treatment and serial casting should be chosen. The follow up period for surgery performed group ranges usually from 2 to 8 years (not longer than 10–15 years). Thirty years results of Ponseti’s idiopathic clubfoot treatment is with 78% success. In some recent series 95% success rate was reported. Standard conservative treatment (Kite’s) success rates are only 11% to 58% for idiopathic group. Material and Methods: Seventy patients, 115 feet (45 Bilateral, F/M 15/55) were included in the study. 28 of these patients were neurogenic group (20 Spina Bifida and 8 Artrogripotic). Since 1997, we strove Ponseti’s strict casting protocol. Bensahel’s a la carte PMR surgery was performed in 2 cases. Downey’s MRI evaluation criterias were used. In statistical analysis of the idiopathic, neurogenic and normal groups, ANOVA test was used. Results: The Navicular angle assessment was statistically significant (p< 0.05). Assessment of the results of idiopathic group was in normal range. Pathological components of Clubfoot were significantly reduced in the neurogenic group. Conclusions: Ponseti method is the effective treatment way of both the idiopathic clubfoot and the neurogenic foot. It is concluded that sound understanding of the anatomy of the foot, the biological response of young connective tissue and bone to changes in direction of mechanical stimuli, can gradually reduce or almost eliminate these deformities in most clubfeet

We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity. We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary

Little is known about the risk of later development of osteoarthritis after operative clubfoot correction. There are only a few long-term reports of 30 years and more after operative correction with a standard technique. Slight deformity after correction of an idiopathic clubfoot may be well tolerated by children and young adults. However, if these slight deformities become symptomatic with advancing age remains unsettled. To answer this question, a long-term follow-up of more than 30 years is needed. Functional and radiological correlation is poor in the adult foot with a slight under-corrected clubfoot deformity. A computer-assisted foot scan will provide the exact static and dynamic measurement of the pressure under each part of the foot at every moment of gait. This instrument allows better analysis of residual clubfoot. Between 1962 and 1966 we operated 15 children with the standard operative technique of Phelps-Codivilla. In all cases there was a persistent deformity after continuous casting since birth. In two cases a heal cord lengthening procedure had been previously performed. Mean age at operation of the four girls and 11 boys was four (1 to 8) years. Six had unilateral involvement, whereas the remaining nine patients required bilateral surgery. In four cases there was a second medial release for relapse. A Steindler procedure was used in two cases and in two cases correction of clawtoes was necessary. Operative technique: Two separate incisions were made. One was longitudinal posterior that enabled lengthening of the heel cord, the tendon of the tibialis posterior and long flexors, as well as release of the posterior capsule. A second incision was made on the medial aspect of the foot in order to release the talonavicular and navicularcuneiform joints. The reduced navicular was fixed with a K-wire. Twelve patients were examined clinically, radiologically and by functional testing after a mean follow-up of 33.5 (34 to 38) years. Eight patients had no pain and were not disturbed. There was a slight malreduction of the subtalar joint, but without any signs of joint degeneration. The foot pressure showed overpressure of the lateral forefoot. Four patients had pain and functional limitation. Their complaints had begun only two to four years earlier, and had been asymptomatic until then. All patients developed osteoarthritis of the subtalar joint, and their foot scans were abnormal. Definitive assessment of the successful treatment of idiopathic clubfoot deformity is only possible with a long-term follow-up study. A slight undercorrection can be functionally well tolerated for a long period of time. The first occurrence of pain is still possible at the age of 35 years and older. A computer-assisted assessment of foot pressure by using a foot scan is a sensitive diagnostic tool

Between 1980 and 2003, 600 patients with idiopathic clubfoot attended our clinic. Until 1989, we manipulated the feet according to the Robert Jones method. After that we changed to the Ponseti method. Depending on the residual deformity at age 3 months, patients underwent either percutaneous Achilles tenotomy or full posteromedial release, as described by McKay, and were supplied with a thermoplastic splint until walking age. Minor changes to the surgical technique were made over the years. At follow-up, a minimum of 2 years postoperatively, the feet were evaluated both according to the McKay scoring method and by a simpler method that correlated well with it. Although our results compare unfavourably with those of Ponseti (80% non-surgical correction), we had excellent overall outcomes, with low revision and complication rates

Purpose: Congenital idiopathic clubfoot is the most common congenital deformity in children and can be a major cause of disability for the child as well as an emotional stress for the parents. The Ponseti method of club-foot correction, consisting of serial manipulations and casting, is now the gold standard of treatment. It has traditionally been described using plaster of Paris (POP) above-knee casts, which are affordable, stiff, and easily moldable. Recently, semi-rigid fiberglass softcast (FSC, 3M Scotchcast) has grown in popularity due to ease of removal, durability, lighter weight, better appearance, ease of cleaning, and water resistance. There are currently no randomized controlled trials to prove its efficacy with respect to POP. The purpose of this study was to determine the influence of choice of cast material on the correction of congenital idiopathic clubfeet using the Ponseti method. Method: A prospective, randomized controlled trial. Based on the results of a pilot study performed at our centre, a sample size of 30 patients was determined to be appropriate. Thirty consecutive patients presenting with congenital idiopathic clubfoot were randomized into POP and FSC groups prior to commencement of treatment with the Ponseti Method. Clubfeet secondary to non-idiopathic diagnoses were excluded. The Pirani classification was used to determine clubfoot severity (less severe, < =4; severe > 4), and for surveillance during casting. The primary outcome measure was the number of casts required to correct the clubfoot deformities to the point where the foot was ready for a percutaneous tendo-achilles tenotomy (TAL) or when the foot was completely corrected (Pirani=0). Secondary outcome measures include: number of casts by clubfoot severity, ease of cast removal, number of methods needed to remove casts, need for percutaneous tendo-achilles tenotomy. Results: Of the 30 patients enrolled, 13 (40%) were randomized to POP and 18 (60%) to FSC. No patients were lost to follow-up. In the POP and FSC groups, eight (67%) and 11 patients (61%) underwent a TAL, respectively. In general, there were no differences in the mean number of casts required for clubfoot correction between the two groups (p=0.13). When analyzed by clubfoot severity, the mean number of casts for each material in the less severe group was equal (3 casts). In the severe group, the mean number of casts in the FSC group (6.4 casts) was considerably higher than for the POP group (4.7 casts) but our study was underpowered to verify this result. According to parents, POP was harder to remove than FSC (p< 0.001). Conclusion: In general, FSC was found to be as efficacious as POP in the correction of idiopathic clubfeet by the Ponseti Method and was the preferred cast material by parents. For stiffer, more severe feet, POP seemed to show a faster correction time than FSC

Aim: To evaluate the initial experience of using the Ponseti Method in the management of idiopathic clubfoot and to identify learning curve problems. Materials and Methods: A retrospective analysis undertaken of 57 feet in 39 patients with CTEV treated by the Ponseti method. The standard protocol described by Ponseti was followed. Pirani’s clubfoot score was used to assess the deformity and the results of treatment. The follow-up in the study ranged from 3 months to 35 months. Denis Brown splints were used full-time for 3 months and at night for 1 year. Results: 47 out of 57 feet had good results with no evidence of recurrence. 10 feet had recurrence and underwent further surgery. If compliance was poor with the Denis Brown splints or if there was a severe initial deformity there was an increased risk of recurrence. 20% had problems with the plaster of Paris cast and the foot slipped out of the Denis Brown splint in 14%. It was noted there were 2 cases of bruising and swelling associated with the removal of the cast and the application of Denis Brown boots which had not previously been reported. Conclusion: This is only a preliminary study and therefore the long-term outcome cannot be assessed. It was noted that attention to detail and appropriate regular follow-up is important in achieving satisfactory results

Aim: This study was designed to investigate the association between clinical assessment International Clubfoot Study Group (ICFSG) and quantitative gait data of the children. Methods: Nineteen patients with 30 surgically treated clubfoot were included in this study. Bilateral involvement was present in 11. Average age was 9 years (range 6–14 years) at the time of last follow-up. Patients were treated with different surgical techniques at early childhood period. At the final follow-up they were evaluated according to ICFSG clinical scale. This rating system is based on three main subgroups of evaluation as morphologic evaluation, functional evaluation and radiological evaluation. The maximum score is 12 in morphologic evaluation, 36 in functional evaluation and 12 in radiological evaluation. The total score is from 0 for a perfect result to 60 for the worst result. Further, a total score of 0–5 is rated as excellent, 6–15 as good, 16–30 as fair and over 30 as poor. Quantitative gait data was collected with the Vicon 370 (Oxford Metrics, Oxford, UK). Two force plates (Bertec, Colombus, Ohio, USA) were used for kinetic analysis. All time-distance (walking velocity, cadence, step time, step length, double support time), kinematic (joint rotation angles of pelvis, hip, knee and ankle in sagittal, coronal and transverse planes) and kinetic (ground reaction forces, moments and powers of hip, knee and ankle) data were processed using Vicon Clinical Manager software package. Spearman correlation analysis was used to evaluate if there is a correlation between total clinical score and gait parameters. Results: Average ICSG score was 8.63 (range 1–29). Outcome was excellent in 16, good in 8 and fair in 6 patients according to ICSG. There was a significant correlation between total ICSG score and walking velocity (rs=−0.195, p=0.004), step length (rs=−0.476, p=0.019), pelvic excursion in sagittal plane (rs=−0.429, p=0.026), hip excursion in sagittal plane (rs=−0.511, p=0.006), knee excursion in sagittal plane (rs=−0.486, p=0.019), Ankle excursion in sagital plane (rs=−0.413, p=0.040), peak ankle plantar flexion moment (rs=−0.600, p=0.039), peak ankle plantar flexion power (rs=−0.487, p=0.025). When we compare the gait parameters between groups only foot progression angle showed a significant difference (p=0.031). Conclusion: ICFSG score is a successful method to follow outcome in patients with surgically treated clubfoot. ICFSG score is correlated with many kinematic and kinetic gait data however foot progression angle is the only parameter predicting outcome in children with surgically treated idiopathic clubfoot. Quantitative gait analysis may help to define the liable factors of the functional deficits, and to prescribe novel rehabilitation techniques to enable better outcome for children with clubfeet

Introduction and Aims: Pivotal to most clubfoot management protocols is Achilles tendon lengthening or tenotomy to address hindfoot deformity. The effectiveness of Botulinum A toxin (BTX-A) in defunctioning the triceps surae muscle complex as an alternative to tenotomy was investigated. Method: Newborns, infants and children referred for suspected clubfoot deformity to the authors’ institution from September 1, 2000 to September 17, 2003 were reviewed consecutively for inclusion in this prospective study. Patients underwent manipulation and castings (above knee casts) emulating Ponseti’s principles until hindfoot stall was encountered. In order to defunction the triceps surae muscle complex, BTX-A at 10 IU per kilogram was injected into this muscle complex. Outcome measures included surgical rate, Pirani clubfoot score, ankle dorsiflexion with knee in flexion and extension, and recurrences. Patients were divided according to age: Group I (< 30 days old) and Group II (> 30 days and < 8 month old). Results: Fifty-one patients with 73 feet met the criteria for inclusion in the study with 29 patients in Group I and 22 in Group II. Mean age of Group I was 16 months (2.5–33 months) and average follow-up was nine months post-BTX-A injection (1 week-27 months post-injection). Mean age of Group II was 23.5 months (3.8–44.6 months) and average follow-up was 15 months post BTX-A injection (1 week–27 months post-injection). Ankle dorsiflexion in knee flexion and extension remained above 20/15 degrees, respectively, and Pirani scores below 0.5 following BTX-A injection for both groups. All but one patient (one foot) who reached the point of hindfoot stall during the protocol of manipulations and castings had successful defunctioning of the triceps surae complex using a single BTX-A injection. This one patient out of 51 (1.9% of patients and 1.3% of feet) did not respond to the protocol. Of the 50 patients who responded to the protocol, nine patients lost some degree of dorsiflexion due to non-compliance with boots and bars, with fitting problems accounting for two cases. All these patients have corrected with either a return to manipulations and casting alone (one patient), or a combination of repeated BTX-A injection and further manipulations and castings (eight patients). Conclusion: These results are comparable to those reported in the literature using Ponseti’s method or the physical therapy method and were achieved without the need of tenotomy or more frequent manipulations. The use of BTX-A as an adjunctive therapy in the non-invasive approach of manipulation and casting in idiopathic clubfoot is an effective and safe alternative and one that may be preferable to parents

Percutaneous Achilles tenotomy is an integral part of the Ponseti technique. Though considered as a simple procedure, many authors have reported serious neurovascular complications that include iatrogenic injury to the lesser saphenous vein, the posterior tibial neurovascular bundle, the sural artery and pseudoaneurysm formation. The authors describe the results of their new tenotomy technique, the ‘Posterior to Anterior Controlled’ (PAC) technique in an attempt to eliminate such complications. This is a prospective study. Infants < 1 year of age with idiopathic clubfoot were taken up for the Ponseti technique of correction. Tenotomy was performed by the ‘PAC’ technique under local anaesthesia if passive dorsiflexion was found to be < 15 degrees. Outcome measures included completeness of the tenotomy (by ultrasonography), improvement in the equinus angle and occurrence of neurovascular complications. 40 clubfeet in 22 patients underwent ‘PAC’ tenotomy. The mean age was 3.5 months. The tenotomy was found to be complete in all cases. The equinus angle improved by an average of 78.5 degrees (range 70–95 degrees), which was statistically significant (p < 0.05, students t test). Mild soakage of the cast with blood was noted in 21 (52.5%) cases. No neurovascular complication was noted. The average follow-up was 12.2 months (range 9–18 months). The ‘PAC’ tenotomy virtually eliminates the possibility of neurovascular damage, maintains the percutaneous nature of the procedure, is easy to learn and can be performed even by relatively inexperienced surgeons safely and effectively as an office procedure under local anaesthesia

Aims. To analyze outcomes reported in studies of Ponseti correction of idiopathic clubfoot. Methods. A systematic review of the literature was performed to identify a list of outcomes and outcome tools reported in the literature. A total of 865 studies were screened following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and 124 trials were included in the analysis. Data extraction was completed by two researchers for each trial. Each outcome tool was assigned to one of the five core areas defined by the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT). Bias assessment was not deemed necessary for the purpose of this paper. Results. In total, 20 isolated outcomes and 16 outcome tools were identified representing five OMERACT domains. Most outcome tools were appropriately designed for children of walking age but have not been embraced in the literature. The most commonly reported isolated outcomes are subjective and qualitative. The quantitative outcomes most commonly used are ankle range of motion (ROM), foot position in standing, and muscle function. Conclusions. There is a diverse range of outcomes reported in studies of Ponseti correction of clubfoot. Until outcomes can be reported unequivocally and consistently, research in this area will be limited. Completing the process of establishing and validating COS is the much-needed next step. Cite this article: Bone Joint Open 2020;1-8:457–464

The Ponseti method of treating club foot has been shown to be effective in children up to two years of age. However, it is not known whether it is successful in older children. We retrospectively reviewed 17 children (24 feet) with congenital idiopathic club foot who presented after walking age and had undergone no previous treatment. All were treated by the method described by Ponseti, with minor modifications. The mean age at presentation was 3.9 years (1.2 to 9.0) and the mean follow-up was for 3.1 years (2.1 to 5.6). The mean time of immobilisation in a cast was 3.9 months (1.5 to 6.0). A painless plantigrade foot was obtained in 16 feet without the need for extensive soft-tissue release and/or bony procedures. Four patients (7 feet) had recurrent equinus which required a second tenotomy. Failure was observed in five patients (8 feet) who required a posterior release for full correction of the equinus deformity. We conclude that the Ponseti method is a safe, effective and low-cost treatment for neglected idiopathic club foot presenting after walking age


Aims

The study was undertaken to compare the efficacy of Woodcast splints and plaster-of-Paris casts in maintaining correction following sequential manipulation of idiopathic clubfeet.

Methods

In this randomized prospective trial, 23 idiopathic clubfeet were immobilized with plaster-of-Paris casts and 23 clubfeet were immobilized with a splint made of Woodcast that encircled only two-thirds the circumference of the limb. The number of casts or splints needed to obtain full correction, the frequency of cast or splint-related complications, and the time taken for application and removal of the casts and splints were compared.

Introduction: Congenital clubfeet have increasingly been detected in routine prenatal ultrasound. However, many clubfeet are still missed and surprise the mothers at birth. The complex deformity and different treatment options available seem to make prenatal counseling desirable. Despite published studies on prenatal clubfoot diagnosis by ultrasound, it is unknown if mothers would indeed prefer to know about their child’s clubfoot before birth or not.

Methods: This survey included patients born between 2000 and 2007 who were treated for congenital clubfoot at one of the two participating institutions (center one: East coast USA; center two: Austria). Exclusion criteria were defined as underlying syndrome, genetic abnormality or pregnancy with multiple fetuses. A brief survey about the opinion of mothers towards ultrasound diagnosis of clubfoot consisting of three questions was sent out. A computer database was created for data collection and a statistic analysis was performed.

Results: Surveys were sent out to 401 mothers of patients meeting inclusion criteria. A total of 220 surveys were received back with 105 surveys from center one and 115 surveys from center two. In 97 cases the clubfoot was unilateral and in 123 cases bilateral. Routine ultrasound showed a clubfoot in 91 cases (41%) and failed to show the deformity in 128 cases (59%). The detection rate in center one was 60% compared to 25% in center two. Bilateral clubfeet had a detection rate of 53% whereas unilateral clubfeet had a detection rate of 29%. Between 2000 and the end of 2003 the overall detection rate was 31% versus 50% between 2004 and the end of 2007.

Overall 74% of mothers wanted to know about their baby’s clubfoot before birth and 24% after birth. Of the 91 mothers who had a positive ultrasound 96% wanted to know before birth. Of the 128 patients who had a negative ultrasound 59% would have wanted to know while 38% did not want to know about the clubfoot prenatally. In center one 89% of mothers wanted to know before birth versus only 60 % in center two. Comments on the survey form showed that mothers who had or wanted to have the prenatal diagnosis appreciated the time to prepare and to find out more about the condition and different treatment options. Many wished for more information at the time of prenatal diagnosis. Mothers that would prefer to find out about the clubfoot postnatally feared that the diagnosis would have affected the experience of the pregnancy.

Discussion: Although the detection rate increased over time there are still cases of clubfeet missed in the routine ultrasound, especially in center two where the rate of detection was low. Mothers in the US are more reluctant to know before birth than mothers in Austria which is most likely related to the differences in the two health care systems. Detailed information about the nature and treatment of clubfeet should be given at prenatal diagnosis.
