Aims. There is a lack of high-quality research investigating outcomes of Ponseti-treated idiopathic clubfeet and correlation with relapse. This study assessed clinical and quality of life (QoL) outcomes using a standardized core outcome set (COS), comparing children with and without relapse. Methods. A total of 11 international centres participated in this institutional review board-approved observational study. Data including demographics, information regarding presentation, treatment, and details of subsequent relapse and management were collected between 1 June 2022 and 30 June 2023 from consecutive clinic patients who had a minimum five-year follow-up. The clubfoot COS incorporating 31 parameters was used. A regression model assessed relationships between baseline variables and outcomes (clinical/QoL). Results. Overall, 293 patients (432 feet) with a median age of 89 months (interquartile range 72 to 113) were included. The relapse rate was 37%, with repeated relapse in 14%. Treatment considered a standard part of the Ponseti journey (recasting, repeat tenotomy, and tibialis anterior tendon transfer) was performed in 35% of cases, with soft-tissue release and osteotomies in 5% and 2% of cases, respectively. Predictors of relapse included duration of follow-up, higher initial Pirani score, and poor Evertor muscle activity. Relapse was associated with poorer outcomes. Conclusion. This is the first multicentre study using a standardized COS following clubfoot treatment. It distinguishes patients with and without relapse in terms of clinical outcomes and QoL, with poorer outcomes in the relapse group. This tool allows comparison of treatment methods and outcomes, facilitates information sharing, and sets family expectations. Predictors of relapse encourage us to create appropriate treatment pathways to reduce relapse and improve outcome. Cite this article: Bone Joint J 2024;106-B(7):735–743

The Ponseti method has been proven to be the gold standard of treatment for clubfoot. The question however remains about the treatment of atypical and complex feet with this method. The Ponseti technique has been used to treat all clubfeet at the our institution for the past 10 years. We interviewed 70 patients (114 affected feet) ages 5–9 regarding the current state of their clubfoot using the 10 item Disease Specific Instrument (DSI) developed by Roye et al. Of these, 16 patients had a complex foot defined by a transverse medial crease. The DSI scores from all patients were transformed onto a 100 point scale and compared based on overall score as well as functional outcome and satisfaction. There was no significant difference in the overall scores with a mean of 76.43 (sd= 21.1) in patients who did not have a complex deformity compared to a mean of 79.17 (sd= 19.4) in those who did have a complex foot (p=0.644). On the functional subscale the mean scores were 74.07 (sd=27.1) and 89.58 (sd=25.9) for patients who had non-complex and complex feet, respectively (p=0.474). Regarding satisfaction, the non-complex group had a mean score of 79.51 (sd=19.7) compared to the mean of 78.75 (sd=16.7) in the complex group (p=0.888). Primary treatment with the Ponseti method achieves very successful correction of the clubfoot deformity with good outcome scores. Furthermore, even in patients with a complex deformity, the Ponseti method still achieves equally successful outcomes

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.

Clubfoot is one of the commonest congenital abnormalities and is 2–3 times commoner in African populations than Caucasian. From December 2000 in Lilongwe, Malawi, the Ponseti method was used for treatment of this condition combined with the Colombian Clubfoot Score. Over the study period 150 patients were treated, with an average age on presentation of 5.5 months. 43% of cases had completed the manipulation and casting part of treatment and 5.5 months. 43% of cases had completed the manipulation and casting part of treatment and had been braced, but 75% of these were no longer attending regular follow up. We believe that the method is useful for treating CTEV in Africa, but that the intensive nature of the therapeutic regime leads to compliance difficulties

Aims. The Ponseti method is an effective evidence-based treatment for clubfoot. It uses gentle manipulation to adjust the position of the foot in serial treatments towards a more physiological position. Casting is used to hold the newly achieved position. At first, the foot resists the new position imposed by the plaster cast, pressing against the cast, but over time the tissues are expected to adapt to the new position and the force decreases. The aim of this study was to test this hypothesis by measuring the forces between a clubfoot and the cast during treatment with the Ponseti method. Patients and Methods. Force measurements were made during the treatment of ten idiopathic clubfeet. The mean age of the patients was seven days (2 to 30); there were nine boys and one girl. Force data were collected for several weeks at the location of the first metatarsal and the talar neck to determine the adaptation rate of the clubfoot. Results. In all measurements, the force decreased over time. The median (interquartile range) half-life time was determined to be at 26 minutes (20 to 53) for the first metatarsal and 22 minutes (9 to 56) for the talar neck, suggesting that the tissues of the clubfoot adapt to the new position within several hours. Conclusion. This is the first study to provide objective force data that support the hypothesis of adaptation of the idiopathic clubfoot to the new position imposed by the cast. We showed that the expected decrease in corrective force over time does indeed exist and adaptation occurs after a relatively short period of time. The rapid reduction in the forces acting on the foot during treatment with the Ponseti method may allow significant reductions in the interval between treatments compared with the generally accepted period of one week

Aims. The gold standard for percutaneous Achilles tendon tenotomy during the Ponseti treatment for idiopathic clubfoot is a tenotomy with a No. 15 blade. This trial aims to establish the technique where the tenotomy is performed with a large-bore needle as noninferior to the gold standard. Methods. We randomized feet from children aged below 36 months with idiopathic clubfoot on a 1:1 basis in either the blade or needle group. Follow-up was conducted at three weeks and three months postoperatively, where dorsiflexion range, Pirani scores, and complications were recorded. The noninferiority margin was set at 4° difference in dorsiflexion range at three months postoperatively. Results. The blade group had more dorsiflexion at both follow-up consultations: 18.36° versus 18.03° (p = 0.115) at three weeks and 18.96° versus 18.26° (p = 0.001) at three months. The difference of the mean at three months 0.7° is well below the noninferiority margin of 4°. There was no significant difference in Pirani scores. The blade group had more extensive scar marks at three months than the needle group (8 vs 2). No major complications were recorded. Conclusion. The needle tenotomy is noninferior to the blade tenotomy for usage in Ponseti treatment for idiopathic clubfoot in children aged below 36 months.

Purpose: To evaluate the predictive value of a prenatal ultrasound diagnosis of clubfoot, the ability to differentiate isolated clubfoot from complex clubfoot, and establish valid recommendations for follow-up and additional investigations. Materials and Methods: Clubfoot (CF) was diagnosed by prenatal ultrasound (US) in 85 feet in 48 fetuses at a mean gestational age of 21.6 weeks (14–35.6). All mothers were examined prenatally in a multidisciplinary clinic for fetal abnormalities. Postnatal outcome was obtained by chart review (24) or telephone interview (24) and feet were classified as Normal (N), Positional Deformity (PD), Isolated Clubfoot (ICF) and Complex Clubfoot (CCF). Results: At initial diagnosis, 65 feet in 38 fetuses were classified as ICF and 20 feet in 10 fetuses as CCF. Diagnosis was changed during follow-up US in 12 fetuses (25%) and final US diagnosis was N in one, ICF in 29 and CCF in 18 fetuses. Post natal clubfoot was found in 73 feet in 40 children giving a positive predictive value (PPV) of 85%. Accuracy of specific diagnosis was significantly lower – 65% initially and 75% at final US. No post natal CCF had been undiagnosed and inaccuracies were all overdiagnoses. 24 kariotypes were performed. Three were abnormal but had additional US findings and had been classified as CCF. No abnormal kariotypes were found in fetuses diagnosed as ICF. Conclusions:. The prenatal diagnosis of clubfoot carries a positive predictive value of 87% with lower values of ICF (76%) and CCF (69%). The diagnostic accuracy increases with follow up ultrasound examinations which should be performed periodically. The most problematic diagnosis to rule out is arthrogryposis and further diagnostic modalities should be researched. When Isolated Clubfoot is diagnosed, the indication for amniocentesis and kariotyping is questionable

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

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

Untreated clubfoot results in serious disability, but mild to moderate residual deformities can still cause functional limitations and pain. Measuring the impact of clubfoot deformities on children's wellbeing is challenging. There is little literature discussing the variability in outcomes and implications of clubfoot based on where geographically the child resides. Although the use of patient reported outcome measures (PROMs) is steadily growing in pediatric orthopaedics, few studies on clubfoot have incorporated them. The most widely used PROM for pediatric foot and ankle pathology is the Oxford Foot and Ankle Questionnaire for Children (OXFAQ-C) that include a physical, school and play, emotional and shoe wear domains. The aim of this study is to evaluate the validity and regional differences in scores of the OXFAQ-C questionnaire to identify functional disability in children with clubfoot in India and Canada. This is a retrospective cohort study of children in Indian and Canadian clubfoot registries aged 5-16 years who completed >1 parent or child OXFAQ-C. The OXFAQ-C was administered once in 01/2020 to all patients in the Indian registry, and prospectively between 06/2019 and 03/2021 at initial visit, 3, 6, 12 months post-intervention, then annually for the Canadian patients. Demographic, clubfoot, and treatment data were compared to OXFAQ-C domain scores. Descriptive statistics and regression analysis were performed. Parent-child concordance was evaluated with Pearson's Coefficient of Correlation (PCC). The cohort had 361 patients (253 from India, 108 from Canada). Non-idiopathic clubfoot occurred in 15% of children in India and 5% in Canada, and bilateral in 53% in India and 50% in Canada. Tenotomy rate was 75% in India and 62% in Canada. Median age at presentation was 3 months in India and 1 month in Canada. Mean Pirani score at presentation and number of Ponseti casts were 4.9 and 6.1 in India and 5.3 and 5.7 in Canada, respectively. Parents reported lower scores in all domains the older the child was at presentation (p Canadians scored significantly lower for all domains (p < 0 .001), with the difference being larger for child-reported scores. The greatest difference was for physical domain. Canadian parents on average scored their child 6.21 points lower than Indian parents, and Canadian children scored a mean of 7.57 lower than Indian children. OXFAQ-C scores differed significantly between Indian and Canadian children despite similar demographic and clubfoot characteristics. Younger age at presentation and tenotomy may improve OXFAQ-C scores in childhood. Parent-child concordance was strong in this population. The OXFAQ-C is an adequate tool to assess functional outcomes of children with clubfeet. Cultural validation of patient reported outcome tools is critical

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

Background. The gold standard of care of clubfoot is the Ponseti method of serial manipulation and casting, followed by percutaneous tendo-achilles tenotomy. In our setting, registrars work in district hospitals where they run Ponseti clubfoot clinics with little or no specialist supervision. They use the Pirani score to serially assess improvement of the deformity during casting and to determine whether the foot is ready for tenotomy. Purpose of Study. To test the inter-observer reliability of the Pirani score, and whether it can be used by non-specialist doctors running Ponseti clubfoot clinics. Methods. Ethics permission was obtained from our institution. This is a prospective study where patients under the age of one year with idiopathic clubfoot were recruited from clubfoot clinics at our institution, over a period of four months. Following a training session using the original description of the score, each foot was independently assessed using the Pirani score by two paediatric orthopaedic surgeons, two orthopaedic registrars and two medical officers. The inter-observer reliability was assessed using the Fixed-marginal Kappa statistic and Percentage agreement. The first 15 feet were used as a learning curve, and hence excluded from final analysis. Results. 73 feet in 37 patients with idiopathic clubfoot (25 boys, 12 girls) under the age of 1 year were included in the study. The Kappa statistic and percentage agreement for the six variables of the Pirani score were determined. Whilst the overall agreement was determined by the Kappa statistic to be slight to fair, the two consultants were found to have a higher inter-observer reliability than the registrars and medical officers. Conclusion. Our results conflict with previously published studies in that the inter-observer reliability of the Pirani score was poor. In addition, we feel that this score cannot be reliably used by non-specialist doctors running Ponseti clubfoot clinics. NO DISCLOSURES

The authors provide an analysis of the results of surgery for clubfoot at the Vilnius University Children’s Hospital in Lithuania from 1979 to 1999. We operated 565 clubfeet in 464 patients. Average age of the patients was 4.1 years. From 1979 to 1993, 172 feet were operated. Most patients had the so-called Zacepin procedure for clubfoot release that contains a multi-stage release of different clubfoot components, but without attention to bony alignment restoration. At that time most patients were operated from 1.5 to 4 years of age. In that group 45% of the patients had a recurrence of the deformity and an additional operation was necessary. From 1993 to 1999, 393 clubfeet were operated. Mean age of the patients was 2.7 years (range 6 months to 7.4 years.). A more extensive release was introduced using the Cincinnati approach and restoration of normal talocalcaneal and talonavicular alignment following adequate soft tissue release. In this group 14% of the patients had a recurrence. The main goal of the clubfoot surgery was an exact reposition and fixation of the talocalcaneal and talonavicular alignment with adequate soft tissue release. The Cincinnati approach was the most effective and safe for correcting all of the components of the deformity. The best results were found in the patients who were operated at the age of six to eight months. In order to get a better functional outcome, at three to four years of age a number of our operated patients required an additional procedure such as a split tibialis anterior tendon transfer, a lateral column shortening, or a medial column lengthening. An excessive reposition of the talus produces a strange and severe foot deformity that is difficult to manage

Introduction: Children with clubfoot treated by the Ponseti method of clubfoot management require anterior tibialis tendon transfer if there is persistent varus and supination deformity. However the size of bone is a determining factor in whether this transfer can be carried out. We have assesses the difference in the age at which the lateral cuneiform ossifies in normal feet compare with clubfeet. Methods: Foot x-rays of children less than 4 years old (AP view) carried out between 2003 and 2005 were obtained from the Radiology department Booth Hall Children’s Hospital. A total of 341 radiographs were analyzed. Exclusion criteria included: any condition affecting foot anatomy or weight bearing or any previous surgery (including surgery for clubfoot). The lateral cuneiform was measured with 1mm accuracy in the longest diameter. Results: We analysed the size of the lateral cuneiform in patients with and without clubfoot in relation to age. In children without clubfoot there was a R2 value of 0.517, showing a positive correlation between age and size of the bone. In children with clubfoot, R2 value was 0.207 showing no correlation between age and ossification rate of the lateral cuneiform. In addition, we compare the size of the lateral cuneiform between patients with and without clubfoot at different ages. There was a significance difference in the level of ossification of the lateral cuneiform in all age groups. In addition, a greater number of patients with no ossification of the lateral cuneiform were found amongst the clubfoot group in all age groups up to the age of 36 months. Conclusions: We have identified a delayed ossification in the lateral cuneiform in children with clubfoot when compared with normal feet. This delayed ossification should be taken into account when considering anterior tibialis tendon transfer for correction of clubfoot

Rocker bottom deformity may occur during the conservative treatment of idiopathic congenital clubfoot. Between 1975 and 1996, we treated 715 patients (1120 clubfeet) conservatively. A total of 23 patients (36 feet; 3.2%) developed a rocker bottom deformity. It is these patients that we have studied. The pathoanatomy of the rocker bottom deformity is characterised by a plantar convexity appearing between three and six months of age with the hindfoot equinus position remaining constant. The convexity initially involves the medial column, radiologically identified by the talo-first metatarsal angle and secondly by the lateral column, revealed radiologically as the calcaneo-fifth metatarsal angle. The apex of the deformity is usually at the midtrasal with a dorsal calcaneocuboid subluxation. Ideal management of clubfoot deformity should avoid this complication, with adequate manipulation and splinting and early Achilles’ percutaneous tenotomy if plantar convexity occurs. Adequate soft-tissue release provides satisfactory correction for rocker bottom deformity. However, this deformity requires more extensive and complex procedures than the standard surgical treatment of clubfoot. The need for lateral radiographs to ensure that the rocker bottom deformity is recognised early, is demonstrated

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

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

Background. Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children, or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severe neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has excellent functional outcome. Objective. To assess the functional outcome of acute correction of neglected Talipes-quino-varus deformity in adults. Methods. This is cross sectional, hospital–based study that took place in Khartoum, Sudan. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed to all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopaedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one years after surgery. Results. The mean age was 19.9±4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7±7.1 (poor). This score improved to 80.7±13.7 (good to excellent), two years after surgery. However, this indicates significant change in the functional outcome after the operation (P value < 0.05). Excellent post-operative functional outcome was found among patients aged 18 – 23 years 18 (50%) P. value: 0.021. The majority of patients 36(90%) were fully satisfied with the operation, 2(5%) partially satisfied and 2(5%) were unsatisfied. Conclusion. Acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure

Clubfoot is medically defined as luxatio pedis sub talo. The process of dislocation mostly caused by muscular imbalance results in bony deformities and soft tissue contractures, which in the majority of cases – even after meticulous conservative treatment – have to be corrected by surgery. In children before school age, surgical corrections should always address the main pathology. To achieve normal alignment of the fore and hindfoot, a complete reduction of the talus within the acetabulum pedis has to be done by soft tissue release. Analysing the pathomorphology, a clubfoot is characterised by equinus, varus, forefoot adduction, and horizontal subtalar medial rotation. Regarding bony deformation, the medial side of the talus is narrowed by the navicular, the medial malleolus, and the fibrocartilage between. Growth expansion is limited on the medial side and there is more growth expansion on the lateral convex side, leading to external rotation of its body (~ 10-25°) and internal inclination of the neck (~30-50°). The calcaneus is internally rotated 20-30°. Regarding joint dislocation, there is a displacement of the navicular medially and plantarward towards the medial malleolus. The cuboid bone usually follows the position of the navicular and dislocates gradually to the medial side. Soft tissue contractures are located medially (Lacinate Lig., M. Add. hallucis, Spring Lig., talo navicular Lig., Master knot of Henry) and posterior (lat. fibulo calc. Lig, post. capsule of the ankle joint). There is also a shortening of muscles e.g. short plantar flexors, M. tib. post., M. flex. hall. longus., M. flex. digit. comm., M. tib. ant. The method of treatment depends on the severity of a clubfoot, the preoperatively achieved results of conservative treatment, and how extensive a subtalar release has to be performed. If the navicular can be reduced conservatively, a posterolateral surgical approach is indicated. A transversal incision is performed starting laterally at the calcaneal cuboid joint and ending medially below the medial malleolus. A dorso lateral release of the subtalar joint, Tendo Achilles lengthening, and dorsal release of the ankle joint is performed. At the age of three to six months, it is possible to correct subtalar malalignment to move the calcaneus away from the fib. Malleolus by external rotation in relation to the talus (Mini Cincinnati technique). If the talonavicular and the calcaneo-cuboid joint are dislocated, a complete subtalar release has to be done in order to reduce the talo-navicular, calcaneo-cuboid and talo-calcaneal joint. To avoid overcorrection, the talo calcaneal interosseous lig. should be kept intact whenever possible (Mc Kay-Simons procedure). This type of surgery should not be performed before the age of six months. The subtalar release technique described by McKay was introduced in our hospital in 1983. Since then, 362 clubfeet have been treated by the above-mentioned techniques: 249 by the Mini Cincinnati (Group 1) and 113 by the McKay-Simons procedure (Group 2). Age at the time of surgery ranged from 2 to 12 months in Group 1 and 5 to 52 months in Group 2. In Group 1, the results were excellent in 42%, and good (residual forefoot adduction) in 49%. A second surgical intervention had to be done in only 9%. Regarding shape and appearance of the foot in Group 2, results were excellent in 46%, good in 38% and insufficient in 16% (overcorrection 3%, relapse 13 %). Concerning functional outcome, the feet of Group 2 presented much more stiffness than those of Group 1, which was also found pre-operatively. The treatment of clubfoot is still a matter of controversy because of different severity of deformity and different treatment philosophies. According to our experience, the McKay-Simons procedure has proved to be ideal for simultaneous correction of various components of the deformity from one single approach. In particular, correction of subtalar horizontal rotational deformity in the subtalar joint can be easily performed. Based on the survey, the danger of damaging nerves, blood vessels, tendons and joint cartilages can be kept to a minimum by using the Cincinnati approach. In the majority of cases, the foot appears normal, moves without pain, and is flexible enough to enable the child to walk on his toes or heels and to participate in sportactivities. Limitation of mobility is nevertheless the main problem of all extensive soft tissue procedures in clubfoot surgery, and it is not known at this time if this will cause subtalar osteoarthritis in early adulthood. Complete subtalar release develops less osteonecrosis, fewer changes in the navicular, and less cavus and adductus than the use of other surgical techniques. Overcorrection and poor functional results were seen in patients less than six months old at the time of surgery. We recommend that a complete subtalar release be delayed until the child is aged 6 to 12 months. Treatment should ideally be completed by the time the child is ready to walk

Purpose: To elucidate the pathomorphology of the unossified clubfoot and to monitor the progressive correction of the deformity during treatment, the authors introduce a standardized sonographic assessment of the foot at birth and at the end of both conservative and surgical corrective procedures. Methods: 42 congenital clubfeet and 42 normal newborns were documented by ultrasound using a 7,5/10 MHz linear arrays probe with direct contact. Clubfeet were documented in the position of spontaneous alignment and during passive manual correction at the admission and at the end of both conservative and surgical treatment. Five standard ultrasound planes were used: sagittal posterior, sagittal anterior, coronal lateral, transversal and coronal medial plane. Results: On the sagittal posterior plane the progressive gain of the dorsiflexion during the different steps of the treatment was documented measuring the distance between the distal tibial metaphysis and the calcaneal apophysis. In clubfeet, looking at the ossification centre of the talus, both its forfeit of domicile in the ankle mortise and its right positioning after treatment can be showed. On the sagittal anterior plane and on the transversal plane the medial displacement of the navicular is documented. The normalisation of the anatomic alignment of the navicular is well documented by these planes after appropriate treatment. On coronal lateral plane the relationships between the os calcis and cuboid can be estimated using the calcaneal-cuboid angle. The coronal medial plane exhibited a very low reproducibility in the neonatal clubfoot and it is not reccomended. Conclusions: Ultrasonography it is a very promising technique in the monitoring of clubfoot deformity during treatment. On the sagittal posterior and on the coronal lateral planes strictly quantitative information can be easily deduced while prevalently qualitative information are deduced on the sagittal anterior and on the transversal planes. Ultrasound gives exact and reproducible information concerning the pathomorphology of the not ossified
