Pie bot: conceptos actuales / Clubfoot: current concepts

El pie bot es la deformidad congénita más frecuente de las extremidades inferiores del ser humano, afectando a 1 de cada 1000 recién nacidos vivos. Consiste en la presencia de cuatro deformidades estructurales en el pie y el tobillo: cavo del medio pie, aducto del antepié, varo del retropié y pie en equino.Su registro en la humanidad data del siglo XII A.C. en momias del antiguo Egipto.La fisiopatología de esta deformidad aún no está aclarada. El diagnóstico puede ser prenatal mediante visualización ecográfica, pero la forma más común de diagnóstico es postnatal. La evaluación de estos pacientes se basa en la exploración clínica. Entre las clasificaciones más utilizadas se encuentran: Diméglio, que enfatiza lo reductible ante maniobras manuales de la deformidad; Pirani, que evalúa la gravedad inicial y el progreso del tratamiento; y Ponseti International Association (PIA), que clasifica según etiología.Durante el siglo pasado se describieron numerosos procedimientos quirúrgicos, muchos de los cuales fueron quedando en desuso ante sus resultados insatisfactorios, pies rígidos y dolorosos, con función limitada. Actualmente el método Ponseti es el Gold estándar para su tratamiento, consistiendo en una manipulación y enyesado seriado buscando la corrección sistemática del pie, basado en los fundamentos de la cinemática y la fisiopatología de la deformidad.

Clubfoot is the most frequent congenital deformity of the lower extremities of humans, affecting 1 out of 1000 live newborns. It consists of the presence of four structural deformities in the foot and ankle: midfoot cavus, forefoot adductus, hindfoot varus, and equinus foot.Its records in humanity date from the 12th century B.C., in ancient Egyptian mummies.The pathophysiology of this deformity is still unclear. Prenatal diagnosis by ultrasound imaging is feasible, but most common diagnosis is postnatal. The evaluation of these patients is based on clinical examination. Among the most used classifications are: Diméglio, which emphasizes the reductibility with manual maneuvers; Pirani, who assesses initial severity and progress of treatment; and Ponseti International Association (PIA), which classifies according to etiology.During the last century, numerous surgical procedures were described, many of which were disused due to their unsatisfactory results, stiffness and painful feet, with limited functionality. Currently the Ponseti method is the gold standard for its treatment. It consists of serial manipulation and casting, looking for a systematic correction of the deformity, based on the fundamentals of kinematics and pathophysiology of the deformity.

Resumen: Introducción: El pie equinovaro aducto congénito (PEVAC) es una deformidad congénita frecuente del pie. El método Ponseti es el estándar de oro para el tratamiento. Consiste en la manipulación del pie con yesos seriados semanales, una cirugía mínimamente invasiva y barra Dennis-Brown hasta los cinco años. Objetivo: Describir el seguimiento de los pacientes con PEVAC tratados mediante método Ponseti. Material y métodos: Estudio descriptivo, longitudinal, durante 2013-2019, en pacientes con PEVAC manejados con método Ponseti. Se incluyeron pacientes con PEVAC uni- o bilateral, menores de dos años, sin cirugía previa, cuyos padres firmaron consentimiento informado. Se excluyeron pacientes con otras malformaciones. Se colocó yeso semanal seriado por cuatro a ocho semanas, se realizó tenotomía del tendón de Aquiles y yeso por tres semanas más; luego calzado de horma inversa con barra Dennis-Brown. Se registraron las revisiones al día cero, a las ocho semanas y cada tres meses hasta los cinco años de edad. Se valoró la corrección de la deformidad y el dolor a la marcha. Resultados: Fueron 22 pacientes; 17 (77.3%) corrigieron más de 90% de la deformidad, con adecuada funcionalidad y 86.3% sin dolor a la marcha, seguimiento medio de 3.9 años (uno a siete años); seis pacientes tuvieron recidiva (27.27%) por mal apego, uno retratado con yesos y cinco con transferencia de tibial anterior, todos con éxito. Conclusiones: El PEVAC manejado con método Ponseti corrige más de 90% de la deformidad y sin o mínimo dolor con buen apego al tratamiento. Tuvimos una recidiva de 27.27% en nuestra serie.

Abstract: Introduction: Congenital talipes equino varus (club foot) is a frequent congenital deformity of the foot. The Ponseti method is the gold standard for treatment. It consists of foot manipulation with weekly serial cast, minimally invasive surgery and Dennis-Brown bar up to five years. Objective: To describe the follow-up of patients with PEVAC treated using the Ponseti method. Material and methods: Descriptive, longitudinal study, during 2013-2019, in patients with PEVAC managed with Ponseti method. We included patients with uni- or bilateral club foot, under two years of age, without prior surgery, whose parents signed informed consent. Patients with other malformations were excluded. Serial weekly cast was placed for 4-8 weeks, a tenotomy of the Achilles tendon was performed, and cast for three more weeks; then reverse footwear with Dennis-Brown bar. The revisions were recorded at day zero, at eight weeks and every three months up to five years of age. Correction of deformity and pain on walking was assessed. Results: There were 22 patients; 17 (77.3%) corrected more than 90% of the deformity, with adequate functionality and 86.3% without pain on gait, mean follow-up 3.9 years (1-7 years); six patients relapsed (27.27%) due to poor attachment, one re-treated with cast, and five with anterior tibial transfer, all successfully. Conclusions: The club foot managed with Ponseti method corrects more than 90% of the deformity and without or minimal pain with good adherence to treatment. We had a 27.27% recurrence in our series.

A preliminary study on the ultrasonic evaluation of deformity changes during the treatment of congenital clubfoot in infants / 中华超声影像学杂志

Objective:To evaluate the deformity changes in the treatment of congenital clubfoot in infants by ultrasound, and to explore its clinical application value.Methods:Seventeen infants with congenital clubfoot treated in the Department of Pediatric Orthopaedics of the Third Affiliated Hospital of Zhengzhou University from March 2020 to June 2021 and 27 normal infants in the same period were selected. The distance between medial malleolus and scaphoids (MM-N distance) of all feet was measured by ultrasound. The distance from the tangent line of the lateral edge of calcaneus to the midpoint of the lateral edge of the chondroid bone (C-C distance), medial soft tissue thickness and tibial calcaneal angle were measured by ultrasound. The data before, after treatment and during follow-up were statistically analyzed.Results:A total of 88 feet of 44 infants were evaluated. The mean number of cast was 4.7±1.1, the follow-up time was (96.9±59.3)days. The MM-N distance, C-C distance and posterior tibial calcaneal angle in the clubfoot group were improved after treatment and at the last follow-up, and the differences were statistically significant (all P<0.01). During the treatment, 1 case had false correction, and 2 cases recurred in the last follow-up. Conclusions:Ultrasound can clearly display the medial, dorsal, lateral and posterior articular structures of normal and clubfoot, and can observe the deformity changes of clubfoot during the correction process, which can provide guidance for the clinical treatment of clubfoot.

Results of Ponseti Casting for Clubfoot in a Tertiary Public Hospital

@#INTRODUCTION: Congenital talipes equinovarus (CTEV), also called clubfoot, is one of the most common orthopedic congenital anomalies. However, there is no formal study of the condition here in the Philippines, and data is sparse regarding the epidemiology, treatment, and outcomes in similar third-world countries. METHODS: Retrospective review of data of clubfoot patients seen at the Philippine General Hospital (PGH) Clubfoot Clinic from 2006 up to the present. RESULTS: Records from 75 patients treated at the PGH Clubfoot Clinic from 2010-2016 were reviewed. Idiopathic clubfoot comprised 76% of the patients, while syndromic clubfoot comprised 24%. A good outcome of the Ponseti method was seen in 82% and 88% of the idiopathic and syndromic clubfoot patients, respectively. Idiopathic clubfoot cases that had good outcomes required an average of 11.84 casts to tenotomy or bracing, which was not statistically significant compared to 9.55 average sessions for syndromic clubfoot (p=0.21). The initial Pirani scores for both cases were not significantly different (p=0.95). Idiopathic cases with poor outcomes needed less casting sessions (4.45) because the decision to operate was made early. Age was not found to significantly affect the outcome of treatment for idiopathic clubfoot (p=0.20) and syndromic clubfoot (p=0.64). CONCLUSION: Ponseti casting was found to be effective in treating both idiopathic and syndromic clubfoot patients. The number of sessions did not differ significantly between the two.

Results of ala carte Posteromedial Soft Tissue Release in Idiopathic Clubfoot

@#Introduction: The aim of this study is to assess the outcomes of ala carte posteromedial release in children over two years of age who were not responding to the Ponseti method of treatment of idiopathic clubfoot. Materials and Methods: A retrospective observational study from September 2013 to August 2015 was conducted at a tertiary level medical teaching institution. The clubfeet were classified according to the Harold and Walker classification. Radiographic parameters assessed were the talocalcaneal angle (AP, lateral), talus-first metatarsal angle (AP, lateral) and calcaneal-fifth metatarsal angle. The scar and the functional score, according to Laaveg and Ponseti, were evaluated as outcome measures at the final follow-up. Results: Twenty-four children with a mean age of 43.7 ± 24.7 months were enrolled in the study. There was a total of 36 clubfeet: 21 (65.6%) with a poor functional outcome; 12 (37.4%) with excellent to good scar in both horizontal and vertical components. There was a statistical significance between the pre-operative and post-operative radiological parameters (p<0.05). None of the patients presented with any limitation of activities of daily living despite the poor functional outcome in many of the children. There was no significant association between the qualities of scar (horizontal, vertical) and the functional outcome with age at presentation, pre-operative Harold and Walker classification and pre-operative radiographic angles. Conclusion: Surgical intervention in terms of ala carte posteromedial soft tissue release could not produce a good outcome over four years in CTEV. The threshold for surgery in CTEV should be high, given the poor results.

Therefore, this work opens space for new research that corroborates this theme. (AU)

Apego al método de Ponseti por parte de los familiares como determinante en el éxito del tratamiento del pie equinovaro / Adherence to the Ponseti method by family members as a determinant in the success of club foot treatment

Resumen: El pie equinovaro aducto congénito (PEVAC) es uno de los padecimientos más comunes en Ortopedia Pediátrica, el cual se compone del equino del retropié, el varo subastragalino, el aducto del antepié y el cavo del mediopié. El método de Ponseti es el tratamiento universalmente aceptado para el PEVAC; éste consta de tres fases: manipulación y enyesado, tenotomía del tendón de Aquiles y una fase de mantenimiento. El mayor porcentaje de las recaídas se presenta en la fase de mantenimiento; en la mayoría de los casos, está asociado el apego familiar deficiente. Presentamos el caso clínico de un paciente con PEVAC típico, tratado en cuatro ocasiones con el método de Ponseti y que no requirió tratamiento quirúrgico.

Abstract: The clubfoot is one of the most common conditions in Pediatric Orthopedics, may affect each part of the foot and ankle, equinus, varus, and internal rotation of the calcaneum, and true equinus of the ankle are common. The Ponseti method is an universally accepted treatment, consisting of three phases: manipulation and plaster, Achilles tendon tenotomy and maintenance phase. The highest percentage of relapses occurs in the maintenance phase and the deficient family member is associated in most cases. We present a clinical case of a patient with typical clubfoot treated with the Ponseti method on four occasions without the need of surgical treatment.

Outcome of clubfoot treatment in the pre-ponseti period in a Nigerian teaching hospital: a 14 year review

Background: Congenital Talipes Equinovarus (CTEV) is a common musculoskeletal congenital disorder. Historically, surgical treatment of various types was popular; however, currently the gold standard of treatment is non-operative care using the Ponseti method. This work evaluates the outcome of this former method of managing CTEV before author adopted the Ponseti Method and compares it with the reported outcomes of the Ponseti method in published literature.Methods: A retrospective review of this data from January 1990 to December 2003 was done, the patients demographics, treatment given, duration and outcome of care were analysed using descriptive statistics. This finding was then compared with outcomes of Ponseti method in literature.Results: Here, 145 patients had initial non operative care; eighteen of those patients (12.4%), eventually require either a posteromedial release, a combined posteromedial and posterolateral releases or a triple arthrodesis.Conclusions: The study shows that the success rate of this method of manipulation preceding the adoption of the Ponseti method is 87.6%. This outcome is inferior when compared to the outcome of Ponseti method in published literature. Also, the extensive nature of eventual surgical intervention required to achieve correction is in contrast to the minimal surgeries needed achieve correction of residual deformities following the use of the Ponseti method.

Ponseti method of treating clubfoot - Is there difference if treatment is started before or after one month of age?

@#Introduction: Most of the authors currently agree that congenital talipes equinovarus (CTEV) or idiopathic clubfoot can be effectively treated with the Ponseti method instead of extensive soft tissue surgery. This study was conducted to investigate whether there is a difference in the outcome between starting treatment before one month of age or after that age. Methods: This is a retrospective study on babies with CTEV treated in University Malaya Medical Centre from 2013 to 2017. The 54 babies (35 boys and 19 girls) were divided into two cohorts, Group 1 that had treatment before the age of one month, and Group 2 that had treatment after one month old. The number of cast changes, rate of full correction, and rate of relapse after treatment were compared between the two groups. Results: Of the 54 babies, with 77 CTEV treated during the period, our outcome showed that the mean number of cast change was 5.9 for Group 1 and 5.7 for Group 2. The difference was not statistically significant. All the affected feet (100%) achieved full correction. One foot in the Group 1 relapsed, while three feet in Group 2 relapsed, but the difference was also not statistically significant. All of the relapsed feet were successfully treated with repeated Ponseti method. Conclusions: Treating CTEV using Ponseti method starting after one month was not associated with more casting change of higher rate of relapse

Results of a Standard versus an Accelerated Ponseti Protocol for Clubfoot: A Prospective Randomized Study

BACKGROUND: The aim of this study was to compare the results of the standard once-weekly Ponseti casting technique to an accelerated twice-weekly regimen in our population cohort.METHODS: A prospective randomized controlled study was conducted with a total of 100 consecutive patients (158 feet) being enrolled for the study. Fifty patients were randomized to each group and followed up for at least one year.RESULTS: Initial mean Pirani score was 4.67 ± 0.73 in the standard group and 4.35 ± 0.76 in the accelerated group, and the score decreased to 0.34 ± 0.38 and 0.35 ± 0.31, respectively. Initial mean Dimeglio score was 11.75 ± 2.75 in the standard group and 10.51 ± 2.57 in the accelerated group, and the score decreased to 0.79 ± 0.77 and 0.79 ± 0.71, respectively, immediately after casting. The average number of casts required to correct all the deformities was 6.3 ± 1.2 in the standard group and 6.1 ± 1.4 in the accelerated group (p = 0.45). Average time spent in cast was 58.2 ± 8.3 days in the standard group and 39.5 ± 5.2 days in the accelerated group (p < 0.001). Percutaneous Achilles tendon tenotomy was done in 86.42% in the standard group and in 84.41% in the accelerated group (p = 0.72). Final results were assessed by using a modified functional rating scoring system: 55.55% clubfeet had excellent results and 44.45% had good results in the standard group, whereas 66.23% clubfeet had excellent results and 33.77% had good results in the accelerated group. None amongst the two groups had fair or poor results.CONCLUSIONS: These results suggest that the accelerated Ponseti technique significantly reduces the correction time without affecting the final results and that it is as safe and effective as the traditional Ponseti technique.

A Comparative Correlation between Photographic Assessment of Clubfoot And Delmingo Scoring

Background: The aim of the study is to find correlationbetween photography and Delmingo scoring in the clubfeetmanaged by Ponseti technique.Methods & Materials: Total 30 subjects (42 club feet) werestudied, which were corrected by Ponseti technique. Thesubjects are evaluated photographically and clinically(Delmingo Scoring) both before and after the correction.Results: Severity of the deformities and clinical correction wasassessed by Delmingo Scoring and simultaneously byphotographs. All patients achieved good clinical results. Thepre and post correction difference in photographically wasstatistically significant.Conclusion: 4 photographic views proved as cost effectiveanalysis of its result. Various reported scores for congenitalTalipes Equinovarus are presented with observer variationsand lack in objective evidence of severity of deformity andcorrection was correlated and compared with Pirani scores 0.5-2, 2.5-4, 4.5-6 as grouped I to III for mean and StandardDeviation in 42 club feet in 30 children. Photography gives anobjective assessment of the severity of deformity and can beused as objective evidence of improvement/deterioration ofdeformity.

Major Predisposing Factors Influencing the Suicide by Hanging: A Retrospective Study from a Tertiary Care Government Hospital in Kerala State, South India

Introdcution: A variable incidence of hanging is found assecond major group among the total number of autopsiesdone in the Department of Forensic Medicine, Govt. MedicalCollege, Calicut, Kerala state, South India. The incidences arefound to be varying according to the social and economic statusof the society. This retrospective study was done in a tertiarycare Government Hospital to find the major predisposingfactors influencing the suicide by hanging.Material and Methods: Case history were taken in detailfrom questionnaires to the relations of the deceased and fromPolice. The results were analyzed on the basis of history,postmortem findings and results of laboratory investigations.Results: The age group 16-25 was found to be the mostprevalent (75%) for suicidal hanging. Among the religion,Hindu religion showed the highest (80%) number. Morecases were found among the manual labourers and lowermiddle class people. People without children were moreprone to suicide by hanging. Among the precipitating factors,mental illness was the highest factor. Fracture of hyoid bonewas found during autopsy in majority of cases of completehanging.Conclusion: Psychological upset and educational statusplayed an important role in suicidal hanging. The highestincidence was seen among those with lower educational status.Hence, proper identification of such people and presentingthem to effective counselling may reduce the incident rate.

Reliable Radiologic Parameters to Predict Surgical Management for Clubfoot Treated with the Ponseti Method / 대한정형외과학회잡지

PURPOSE: Several radiologic reference lines have been used to evaluate individuals with a clubfoot but there is no consensus as to which is most reliable. The aim of this study was to identify which radiologic parameters have relevance to the predictability of additional surgery after Ponseti casting on clubfoot and the effect of clubfoot treatments that contain Ponseti casting and additional surgery. MATERIALS AND METHODS: A total of 102 clubfeet (65 patients, 37 bilateral) were reviewed from 2005 to 2013. The patients were divided into two groups (Group A, those for whom the result of the Ponseti method was successful and did not require additional surgery; and Group B, those for whom the result of the Ponseti method was unsuccessful and required additional surgery), and the following parameters were measured on the plain radiographs: i) talo-calcaneal angle on the anteroposterior and lateral view, ii) talo-1st metatarsal angle on the anteroposterior view, and iii) Tibio-calcaneal angle on the lateral view with the ankle full-dorsiflexion state. Each radiograph was reviewed on two separate occasions by one orthopedic doctor to characterize the intra-observer reliability, and the averages were analyzed. Next, 20 cases were chosen using a random number table, and two orthopedic doctors measured the angle separately to characterize the inter-observer reliability. RESULTS: Groups A and B included 73 clubfeet (71.6%) and 29 clubfeet (28.4%), respectively. The initial talo-calcaneal angle and tibio-calcaneal angle in the lateral view were significantly different among the groups. In addition, inter- and intra-observer biases were not detected. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view were significantly different after treatment in both groups. CONCLUSION: Congenital clubfeet treated with the Ponseti method showed successful results in more than 70% of patients. The initial talo-calcaneal angle and tibio-calcaneal angle on the lateral view were the radiologic parameters that could predict the need for additional surgical treatments. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view could effectively evaluate the changes in clubfoot after treatment.

Propuesta de un nuevo diseño de órtesis post-tratamiento de pie equino varo congénito / Proposal for a new design of post-treatment congenital club foot orthosis

La investigación tuvo como objetivo rediseñar la órtesis utilizada post-tratamiento Ponseti, en niños con pie equino varo congénito, de forma tal que permita la reducción de rechazo a su uso. Método: Se identificaron las necesidades de los niños con pie equino varo congénito, para verificar los inconvenientes con respecto a la funcionalidad, diseño y adaptabilidad a la órtesis dado que si la férula no se usa adecuadamente el riesgo de recidiva es de 80 %, por el contrario con el uso de la férula el riesgo es de 4 %. Se realizó un estudio biomecánico del movimiento de un paciente durante el gateo, con y sin la órtesis. Resultados: Se elaboró un modelo 3D de la propuesta, para simular el diseño sometido a las fuerzas generadas por los bebés durante el pataleo en posición supina. Se evaluó experimentalmente el desempeño del prototipo alfa, para determinar si cumplía con la meta prevista. Se obtuvo la fabricación y pruebas de la órtesis en plataforma virtual y físico. Acorde al alcance del proyecto, se determinó que es probable que se reduzca el rechazo al uso y por consiguiente la formación de recidiva, al reducir los factores determinantes propios de la férula del mercado, que propiciaban el mal uso de esta en el tratamiento. La velocidad promedio de gateo es de 0.48 m/s y con la férula se reduce a 0.37 m/s. Discusión: La férula del mercado pesa 304.07 g y la propuesta pesa 209.26 g. Se sugiere que se continúe la investigación en el estudio biomecánico.

This research was developed with the objective of redesigning the orthosis used in the post- Ponseti treatment in children with clubfoot, with the intention of reducing the rejection to its use. Method: A research on the needs of children with congenital clubfoot was conducted to identify the disadvantages on functionality, design and adaptability of the orthosis if the splint is not used appropriately, the risk of relapse is 80 %, whereas using the splint, the risk is 4 %. A biomechanical study of a patient's movement during the crawl was performed with and without the orthosis. Results: A 3D model of the design was developed to simulate computationally its performance under the forces generated by the babies during the kick in supine position. Finally, an experimental evaluation of the alpha prototype performance was made to determine whether it met the intended goal. Thus, the manufacturing and testing of the orthosis on virtual and in physical platform took place. Taking in account the goal of this project, it 3 was determined that it is possible to reduce the reject to the use and therefore the formation of relapse by reducing the determinant factors of the common market splint, which promotes its incorrect use of this in the treatment. The average crawl speed is 0.48 m/s and with the splint, it decreases to 0.37 m/s. Discussion: The weight of the common market splint is 304.07 g and the weight of the one designed in the study is 209.26 g. Further biomechanical research is suggested to get conclusive results

Resultados del tratamiento de pie equinovaro congénito con el método de Ponseti / Outcomes of congenital clubfoot treatment using the Ponseti method

Introducción El pie equinovaro congénito es la deformidad congénita más frecuente del pie. Actualmente, el método Ponseti es el método de referencia para el tratamiento de esta anomalía, pues provee de una corrección completa de las deformidades con buena movilidad y función del pie. Existen muchos estudios en el mundo que muestran resultados funcionales del método. Sin embargo, en Colombia no hay publicaciones de este tipo con el método Ponseti. Materiales y métodos Este es un estudio descriptivo, retrospectivo, de tipo serie de casos en pacientes entre 0 y 12 años diagnosticados con pie equinovaro congénito, tratados con el método Ponseti entre julio de 2002 y diciembre de 2015. Con un seguimiento mínimo de menos 6 meses, se midió la gravedad según la escala de Dimeglio y la funcionalidad según la escala de Laaveg-Ponseti. Resultados 123 pacientes (183 pies) con un seguimiento medio de 8 años. Edad de inicio del tratamiento: entre 0 y 24 meses. Según la clasificación del grado de gravedad de Dimeglio, el 6,5% eran leves, el 74% moderados, el 13% graves y el 6,5%, muy graves. La mayoría de los pies estudiados era de origen idiopático (96%). El 20% presentaron recidiva. Los resultados funcionales según la escala de Laaveg-Ponseti fueron excelentes (71%), buenos (23%) o regulares (6%). Discusión Nuestros resultados con desenlaces buenos y excelentes del 94% son similares a reportes previos. Con una recidiva del 17,8%, en la bibliografía se reportan el 20 y el 40%, respectivamente. Este estudio, a diferencia de los demás, no encontró relación directa entre el uso del aparato de abducción y la recidiva. No hubo sobrecorrecciones y ningún paciente tuvo un resultado malo según la escala de Laaveg-Ponseti. Nivel de evidencia clínica Nivel IV.

Background Congenital clubfoot is the most common congenital deformity of the foot. The Ponseti method is currently the gold standard for the treatment of this anomaly, as it provides a complete correction of the deformities with good foot mobility and function. There are many studies from all over the world that present the functional results of the method. However, in Colombia there are no publications of this type using the Ponseti method. Materials and methods This is a descriptive, retrospective, case series-type study in patients between 0 and 12 years old diagnosed with clubfoot, and treated using the Ponseti method between July 2002 and December 2015, and with a minimum follow-up of at least 6 months. Severity was measured according to the Dimeglio scale, and functionality with the Laaveg-Ponseti scale. Results The study included a total of 123 patients (183 feet) with a mean follow-up of 8 years. Treatment was started between 0 and 24 months. According to Dimeglio severity rating, 6.5% were mild, 74% moderate, 13% severe, and 6.5% very severe. Most (96%) of the studied feet were of idiopathic origin. There was a relapse in 17.8%. The functional results, according to the Laaveg-Ponseti scale were excellent in 71%, good in 23%, and average in 6%. Discussion The results with good and excellent outcomes of 94% are similar to previous studies. With a relapse rate of 17.8%, compared to the 20% and 40%, respectively, reported in the literature. This study, unlike the others, found no direct relationship between the use of the abduction apparatus and relapse. There were no over-corrections and no patient had a poor outcome according to the Laaveg-Ponseti scale. Evidence level IV.

Can the Pirani Score Predict the Number of Casts and the Need for Tenotomy in the Management of Clubfoot by the Ponseti Method?

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

Correlation of Foot Bimalleolar Angle and Ultrasonography in Assessing the Severity of Club Foot in Neonates Treated by the Ponseti Method

@#Introduction: Correlation of Pirani score and foot bimalleolar (FBM) angle has been used in few studies but correlation of FBM angle with ultrasonography has never been evaluated so they are being correlated in assessing the severity of clubfoot in neonates treated by Ponseti method. Material and Methods: Thirty-two feet with congenital talipes equinovarus (CTEV) deformity in neonates were prospectively treated by the Ponseti method. FBM angle and ultrasound parameters were measured three times i.e. at the time of initial presentation, at four weeks of treatment and at completion of treatment. The feet were divided according to the Pirani score in groups: one (0-2.0), two (2.5-4) and three (4.5-6). Correlation between FBM angle and ultrasound parameters were evaluated using Pearson correlation/regression. Results: Correlation between FBM angle and ultrasound parameters were statistically significant (p-value < 0.05). Conclusion: Ultrasound has the potential to accurately depict the pathoanatomy in clubfoot. FBM angle and ultrasound are objective methods to assess the severity of clubfoot. FBM angle and ultrasonography correlated in severity of deformity and correction achieved along the course of treatment.

Nivel de evidencia y grado de recomendación del uso del método de Ponseti en el pie equino varo sindromático por artrogriposis y síndrome de Moebius: una revisión sistemática / Evidence level and grade of recommendation of the Ponseti method for arthrogryposis-related syndromic talipes equinovarus and Moebius syndrome: a systematic review

Resumen: Antecedentes: El pie equino varo aducto congénito (PEVAC) es una malformación musculoesquelética común que afecta de uno a 4.5 de cada 1,000 nacidos vivos; se asocia de manera común a artrogriposis y síndrome de Moebius; éstos son más difíciles de tratar y requieren de tratamientos quirúrgicos agresivos para lograr un pie plantígrado; por lo tanto, ¿cuál es el nivel de evidencia y grado de recomendación del uso del método de Ponseti en el pie equino varo sindromático por artrogriposis y síndrome de Moebius? Métodos: Estudio de diseño de revisión sistemática de acuerdo a las recomendaciones del grupo Cochrane por medio de la identificación de Medical Subject Headings (MeSH) y del método booleano para ubicar artículos que cumplieran con los criterios de selección mediante búsqueda de fuentes primarias como OVID, Cochrane, EBSCOhost, Elsevier, Medigraphic. Resultados: En total, seis artículos cumplieron con los criterios de selección a través de la búsqueda de fuentes primarias: cinco de ellos sobre el tratamiento del PEVAC con método de Ponseti en pacientes con artrogriposis y uno para pacientes con Moebius. Se encontraron artículos con niveles de evidencia y grado de recomendación: IV-D (3), III-D (1) y II (B). Conclusiones: El método de Ponseti es un tratamiento inicial en artrogriposis y síndrome de Moebius; es barato, no invasivo y no requiere de un médico para poderse realizar (pero sí un personal capacitado); se recomienda su uso para evitar cirugías extensas y complicaciones médicas que trascienden al orden económico intrahospitalario.

Abstract: Background: Adduct congenital talipes equinovarus (CTE) or clubfoot is a common musculoskeletal malformation affecting between 1 and 4.5 out of every 1000 live births. It is usually associated with arthrogryposis and Moebius syndrome with the latter two being more difficult to treat as they require aggressive surgery to achieve a plantigrade foot. We therefore ask what is the evidence level and grade of recommendation of the Ponseti method to treat syndromic talipes equinovarus resulting from arthrogryposis and Moebius syndrome. Methods: Systematic review according to the recommendations of the Cochrane group identifying medical subheadings (MeSH) and of the Boolean method to identify the articles that met the selection criteria through the search of primary sources such as OVID, Cochrane, EBSCOhost, Elsevier, Medigraphic. Results: A total of six papers met the selection criteria through the search in the primary sources. Five of them address the treatment of adduct CTE with the Ponseti method in patients with arthrogryposis, and one in patients with Moebius. Evidence levels and grades of recommendation of these papers were: IV-D (3), III-D (1) y II (B). Conclusions: The Ponseti method is an first-line treatment for arthrogryposis and Moebius syndrome. It is unexpensive, non-invasive and does not require a physician to perform it (however, it does require trained staff). Its use is recommended as it avoids extensive surgeries and medical complications that go beyond the hospitals' economic possibilities.

Evaluación ultrasonográfica del tendón de Aquiles en niños con pie equino varo aducto congénito posterior a tenotomía de Aquiles con el método de Ponseti. Seguimiento a 12 semanas / Sonographic evaluation of Achilles tendon healing in tenotomies for congenital clubfoot and Ponseti's treatment. A 12-week follow-up

Resumen: Objetivo: Determinar el tiempo de curación del tendón de Aquiles en pacientes pediátricos tratados mediante tenotomía de Aquiles con método Ponseti en el Hospital Shriners para Niños de México, AC. Material y métodos: Estudio experimental, analítico, prospectivo, longitudinal de pacientes con diagnóstico de pie equino varo aducto congénito idiopático en tratamiento con método Ponseti con evaluación estática y dinámica mediante ecógrafo en tiempo real Siemens Diagnostic Ultrasound System Sonoline 650 con transductor lineal de 10.5 mHz seriada del tendón de Aquiles previa a la tenotomía y a las tres, seis, nueve y 12 semanas tras el tratamiento quirúrgico. Resultados: Se obtuvo una muestra de 23 pacientes, 16 masculinos y siete femeninos, 16 con patología bilateral y siete unilateral, para un total de 39 pies, 18 derechos y 21 izquierdos, con una media de edad de 8.3 ± 2.3 meses. Previamente a la tenotomía, la anchura en corte longitudinal ultrasonográfico media fue de 2.7 ± 0.42 mm; en la semana tres, la media fue 3 ± 0.39 mm; a las seis semanas, 2.92 ± 0.36 mm; el ultrasonido de las nueve semanas reportó media de 2.84 ± 0.38 mm y a las 12 semanas, 2.82 ± 0.39 mm. Se compararon mediante t de Student el ancho prequirúrgico y a las 12 semanas, sin encontrarse diferencia p > 0.03. Conclusiones: La valoración ecográfica muestra integridad a las tres semanas posteriores a la tenotomía de Aquiles. Sin embargo, la reparación completa se logra a las 12 semanas.

Abstract: Objective: The aim of this study was to determine the healing time of Achilles tendon in pediatric patients treated with Achilles tenotomy with the Ponseti method in Shriners Children's Hospital of Mexico, AC. Material and methods: Experimental, analytical, prospective, longitudinal study of patients with a diagnosis of idiopathic congenital clubfoot treated with the Ponseti method with serial static and dynamic evaluation by ultrasound in real time with a Siemens Diagnostic Ultrasound System Sonoline 650, linear transducer 10.5 MHz of Achilles tendon before tenotomy and at three, six, nine and 12 weeks after the surgical treatment. Results: A sample of 23 patients, 16 male and seven female, 16 with unilateral and seven with bilateral pathology was obtained, for a total of 39 feet, 18 right and 21 left, with a mean age of 8.3 ± 2.3 months. Before tenotomy, the width was 2.7 ± 0.42 mm; in week three, the average was 3 ± 0.39 mm; at six weeks, 2.92 ± 0.36 mm; ultrasound at nine weeks reported an average of 0.38 ± 2.84 mm, and 2.82 ± 0.39 mm at twelve weeks. They were compared using Student's t presurgical width and at twelve weeks, without finding difference p > 0.03. Conclusions: Although there is integrity at three weeks after Achilles tenotomy, complete repair is achieved at 12 weeks.

Tratamiento del pie bot idiopático luego de la edad de la marcha: revisión sistemática de la bibliografía / Treatment of the idiopathic clubfoot after the walking age: a systematic bibliographic review

Introducción: La eficacia obtenida con el método de Ponseti en pacientes recién nacidos ha llevado a extender las indicaciones a pacientes de mayor edad. Llevamos a cabo una revisión sistemática de la bibliografía para: 1) definir el grado de comprobación científica con respecto al tratamiento del pie bot con el método de Ponseti en niños >1 año, 2) determinar el número de yesos y procedimientos asociados, 3) determinar el porcentaje de corrección y 4) identificar la tasa de complicaciones. Materiales y Métodos: Utilizando las bases de datos informáticas disponibles en Ovid, PubMed, LILACS y Cochrane Library, se recogieron todos los trabajos sobre pacientes >1 año, con tratamiento de pie bot idiopático mediante el método de Ponseti, publicados hasta el 1 de mayo de 2014. Se revisaron aquellos que cumplieran con criterios de inclusión y exclusión prestablecidos. Resultados: La muestra analizada incluyó 11 estudios con 492 pacientes. La edad promedio al iniciar el tratamiento fue de 3.8 años (rango 1-18). El seguimiento promedio fue de 31 meses. Se realizaron un número promedio de 8 yesos (rango 4-12). Se consiguió un pie plantígrado en el 75% de los casos. La tasa de complicaciones fue del 4,3%. Conclusiones: La evidencia actual en niños >1 año tratados con el método de Ponseti es de nivel IV. Si bien el uso de esta técnica requiere de un mayor número de yesos y procedimientos asociados que en el recién nacido, permite corregir la deformidad, de forma segura, en un alto porcentaje de los casos. Nivel de Evidencia: IV

Introduction: Ponseti´s method efficacy in newborns has led to widen the indications in older patients. A systematic review of the literature was performed to: 1) define the degree of scientific evidence on Ponseti´s method in children over one-year-old with clubfoot; 2) assess the number of casts and associated procedures required to accomplish full correction; 3) determine the percentage of full corrected patients; and 4) identify the rate of recurrence and complications related to this method. Methods: We retrieved from Ovid, PubMed, LILACS and Cochrane Library articles referred to Ponseti´s method in children over one-year-old published until May 1st 2014. Papers that met predetermined inclusion and exclusion criteria were reviewed. Results: Eleven papers met the inclusion criteria. The sample consisted in 492 patients. Average age at the beginning of treatment was 3.8 years (range 1-18). Average follow-up was 31 months. A mean of 8 (range 4-12) casts was required to accomplish full correction. Plantigrade feet were achieved in 75%. Complication rate was 4.3%. Conclusions: Current evidence regarding Ponseti’s method for patients over one-year-old is primarily Level IV. Even though this technique requires higher number of casts and associated procedures, deformity correction is safely achieved in most patients. Level of Evidence: IV
