Objetivo: Evaluar los resultados radiográficos y funcionales al año de la cirugía, en una serie consecutiva de pacientes con diagnóstico de pie plano valgo estadio IIB, sometidos a una osteotomía de Evans sin injerto óseo. Materiales y Métodos: Se evaluó, en forma retrospectiva, a dos grupos de pacientes: grupo 1 (placa con espaciador, n = 12) y grupo 2 (celdas de PEEK, n = 14). La edad promedio era de 47 años (DE 18) en el grupo 1 y de 54 años (DE 12) en el grupo 2. Resultados:Se evaluó a 26 pacientes (28 pies operados); 20 (77%) eran mujeres. Las mediciones radiográficas: ángulo de inclinación del calcáneo, ángulo astrágalo-calcáneo (perfil), ángulo astrágalo-calcáneo (frente), cobertura astragalonavicular, altura de la columna medial, longitud de la columna externa, arrojaron diferencias estadísticamente significativas entre las determinaciones preoperatorias y al año de la cirugía. El puntaje promedio de la escala de la AOFAS al año fue de 96 (DE 4,70) en el grupo 1 y de 95 (DE 4,98) en el grupo 2. El puntaje en la escala analógica visual para dolor fue de 1,2 (DE 0,42) en el grupo 1 y 1,16 (DE 0,46) en el grupo 2.Conclusiones:De acuerdo con los resultados obtenidos, concluimos en que la osteotomía de Evans sin el uso de injerto óseo logra preservar las correcciones obtenidas en el mediano plazo utilizando placas con espaciador o celdas de PEEK. Nivel de Evidencia: III

Objective: To evaluate the radiological and functional outcomes one year after surgery in a consecutive series of patients diagnosed with stage IIB adult-acquired flatfoot deformity who underwent Evans osteotomy without the use of bone graft. Materials and Methods: Two groups of patients were retrospectively evaluated: group 1 (spacer plate, n=12) and group 2 (PEEK cage, n=14). The mean age was 47 years (SD 18) in group 1 and 54 years (SD 12) in group 2. Results:26 patients (28 feet) were evaluated; 14 (84%) of the patients were women. Radiographic measurements calcaneal pitch angle, (lateral) talocalcaneal angle, (AP) talocal-caneal angle, talonavicular coverage angle, medial column height, lateral column length yielded statistically significant differences between preoperative measurements and those taken one year after surgery. The mean score on the AOFAS scale one year after surgery was 96 (SD 4.70) in group 1 and 95 (SD 4.98) in group 2. Regarding the visual analog scale, it was 1.2 (SD 0.42) in group 1 and 1.16 (SD 0.46) in group 2. Conclusions: According to the results obtained, we conclude that Evans osteotomy without the use of bone graft manages to preserve the corrections obtained in the medium term, using either spacer plates or PEEK cages.

Seguridad de los portales para la reparación endoscópica del ligamento calcaneonavicular: estudio cadavérico / Endoscopic Spring ligament repair. Anatomic evaluation of portal safety

Introducción: La lesión del ligamento calcaneonavicular ha sido descrita como una de las causas de la deformidad en el pie plano del adulto. El objetivo de este artículo es describir portales modificados para el diagnóstico y la reparación endoscópica de las lesiones del fascículo superomedial del ligamento calcaneonavicular y evaluar la seguridad de los portales utilizados. Materiales y Métodos:Se llevó a cabo un estudio cadavérico con seis preparados reproduciendo una lesión del fascículo superomedial del ligamento calcaneonavicular con una punta de corte de radiofrecuencia y la posterior reparación endoscópica. Se crearon dos portales modificados para el abordaje. Luego se procedió a la disección anatómica para evaluar la seguridad de los portales en relación con las estructuras anatómicas. El primer portal se realiza inmediatamente proximal a una línea trazada desde la punta del maléolo medial dirigida al centro del talón, el segundo portal se emplaza 0,5 cm proximal a la inserción del tendón tibial posterior en el escafoides por transiluminación. Si es necesario, se coloca un portal accesorio inmediatamente dorsal al tendón tibial posterior a mitad de camino entre los dos portales antes descritos. Resultados:En todos los casos, fue posible la reparación del ligamento con el procedimiento endoscópico. En la disección anatómica de los portales, se observó una distancia promedio a las estructuras vasculonerviosas de 11,83 mm del portal proximal y de 9,66 mm del portal distal. Conclusión: Los portales modificados son seguros y permiten la visualización directa del haz superomedial del ligamento calcaneonavicular y su reparación endoscópica. Nivel de Evidencia: IV

Introduction: Calcaneonavicular ligament injury has been described as a cause of adult flat foot deformity. The objective of this study is to describe modified portals for the diagnosis and treatment of injuries to the superomedial bundle of the calcaneonavicular ligament and to evaluate the safety of the portals used. Materials and Methods: We performed a cadaveric specimen study on 6 feet, where we reproduced a lesion of the superomedial bundle of the calcaneonavicular ligament with a radiofrequency ablation device and repaired it endoscopically. Two modified portals were created for the approach and an anatomical dissection was performed to assess the safety of the portals in relation to the anatomical structures. The first portal was placed immediately proximal to a line drawn from the tip of the medial malleolus toward the center of the heel; the second portal was placed 0.5 cm proximal to the posterior tibial tendon insertion into the navicular bone, guided by transillumination. If needed, an accessory portal was placed halfway between the two previously described portals immediately dorsal to the posterior tibial tendon. Results:In all cases, ligament repair was achieved with the endoscopic procedure. In the anatomical dissection of the portals, we observed an average distance of 11.83 mm from the proximal portal and 9.66 mm from the distal portal to neurovascular structures. Conclusion:Modified portals are safe and allow direct visualization of the superomedial bundle of the calcaneonavicular ligament to perform endoscopic repair. Level of Evidence: IV

Controversy of subtalar arthroereisis in symptomatic flatfoot / 中国骨伤

Flatfoot could be divided into flexible flatfoot and rigid flatfoot. Flatfoot with symptoms is called symptomatic flatfoot, surgical treatment is required if conservative treatment is not effective. Subtalar arthroereisis is a minimally invasive procedure which has been used for many years with good results in flexible flatfoot, however, still has many controversial points. Controversial points focus on indications and contraindications, optimal age, subtalar arthroereisis alone or not, efficacy and safety of absorbable material implants, and implant removal. The paper reviewed and summarized the use and controversies of subtalar arthroereisis in symptomatic flatfoot as follows:the best indication for subtalar arthroereisis was pediatric flexible flatfoot syndrome and aged from 10 to 12 years old was optimal age for treatment;tarsal coalitions with flatfoot and adult flatfoot were relative indications. Stiff flatfoot, joint laxity, and subtalar arthritis were contraindications;obesity and neurogenic flexible flatfoot were relative contraindications. The correction ability of subtalar arthroereisis alone was limited, and it's combined with other procedures depending on patient's situation. The safety and efficacy of absorbable material implants had been reported. Routine removal of the implant was not necessary, the main reason of which was tarsal sinus pain.

Strategies employed in coping with physical disabilities acquired during adulthood in rural South Africa

Society places people with physical disabilities acquired during adulthood in disadvantaged positions, especially when they cannot participate in activities like their non-disabled counterparts. The situation can be worse for individuals who acquire disabilities during adulthood, where they have to learn to cope with the adulthood-acquired physical disabilities. Objectives: This study aimed to identify the types of physical disabilities acquired during adulthood and their causes and explore how participants defined their disabilities and the coping strategies they used. Methods: The study used a phenomenological research design. Five adults (three women, two men) with adulthood-acquired disabilities were purposefully selected from a rural area in Limpopo, South Africa. Data were collected using semi-structured interviews. Thematic analysis was used to generate themes about coping strategies study participants used. Results: The results show four types of adulthood-acquired disabilities amongst the participants: visual impairment, paraplegia, weakened muscles which led to bilateral amputation, loss of function on both hands and legs. Participants' meanings of their physical adulthood-acquired disabilities ranged from a punishment, pain, not a bother, black magic, to results of doing wrong things to someone. In coming to terms with their adulthood-acquired disabilities, participants used problem- and emotion-focused strategies. Four themes from the participants' responses were spiritual support, social support, substance dependency, access to health and rehabilitation services. Conclusion: The study contributes to understanding the experiences of individuals who acquired disabilities in adulthood, how they define their disabilities and the divergent coping strategies they use. This study established that participants used problem-focused, positive emotion-focused and negative emotion-focused coping strategies.

Zone neutre: principe et technique / Neutral zone: principle and technique

L'édentement s'accompagne inévitablement d'une résorption osseuse physiologique des crêtes alvéolaires ou pathologique quand il est mal réhabilité. Ceci conduit à une réduction de la surface d'appui prothétique avec toutes les conséquences anatomo-physiologiques qui en résultent ; compromettant ainsi l'obtention d'un équilibre optimale de la prothèse amovible complète. La détermination et l'enregistrement de la zone neutre par l'empreinte piézographique et son exploitation maximale par la prothèse définitive ; constitue une technique intéressante lorsque d'autres moyens d'optimisation de la rétention et de la stabilité de la PAC (implants, chirurgied'approfondissement vestibulaire) ne peuvent être indiqués. Le but de cet article est de décrire le pas à pas de l'enregistrement de la zone neutre par l'empreinte piézographique en cas d'une crête mandibulaire plate, et de discuter les différentes techniques et matériaux utilisé

Evaluación comparativa del pie plano en preescolares / Comparative assessment of flatfoot in preschool children

Resumen Introducción: El aumento o la reducción del arco longitudinal medial (ALM) puede afectar funciones esenciales en la biomecánica del pie, con repercusiones en la salud a largo plazo. El objetivo del presente estudio fue determinar la altura del ALM en niños de 3 a 6 años, a través de cinco métodos de análisis de huella para el diagnóstico de pie plano. Métodos: Se realizó un estudio observacional transversal con 367 niños de 3 a 6 años en un municipio del Estado de México. Se llevó a cabo una evaluación postural completa, plantoscopía por medio de la clasificación de Viladot y análisis de la huella en pedigrafía, calculando la altura del ALM mediante el ángulo de Clarke (AC), el índice de Staheli (IS), el índice de Chippaux-Smirak (ICS) y el ángulo gamma (Ag). Resultados: La prevalencia de pie plano utilizando el podoscopio fue del 57.7%. Mediante los ángulos y los índices, la prevalencia fue del 86.9% por IS, del 83.3% por ICS, del 95.9% por AC y del 22.3% por Ag. El Ag fue menos sensible para la detección de pie plano en comparación con el ICS, el IS y el AC. Conclusiones: De acuerdo con los resultados del presente estudio, se propone utilizar métodos de análisis de huella para el diagnóstico de pie plano, además de la valoración clásica con el podoscopio. Se recomienda incluir el diagnóstico y la vigilancia del pie plano en la consulta del niño sano, ya que desde edades tempranas puede detectarse la tendencia en la arquitectura podálica.

Abstract Background: The increase or reduction of the medial longitudinal arch (MLA) can affect essential functions in the foot biomechanics with long-term health consequences. The aim of the present study was to determine the height of the MLA in children from 3 to 6 years of age through five methods of footprint analysis for the diagnosis of flat foot. Methods: A cross-sectional observational study was conducted with 367 children aged 3 to 6 years in a municipality of the State of Mexico. We conducted a complete postural evaluation, plantoscopy by Viladot classification, and footprint analysis calculating the height of the ALM using the Clarke angle (CA), the Staheli index (SI), the Chippaux-Smirak index (CSM), and the gamma angle (gA). Results: The prevalence of flat feet using the podoscope was 57.7%. Through the angles and indexes, the prevalence was 86.9% for SI, 83.3% for CSI, 95.9% for CA, and 22.3% for gA. The gA was less sensitive for flat foot detection compared to CSI, SI and CA. Conclusions: Based on the present results, we propose that footprint analysis should be used for flat foot diagnosis besides the classic evaluation by podoscope. We recommend that flat foot diagnosis and surveillance should be included on in the consultation of the healthy child, as a trend for podalic architecture can be detected from early ages.

Objetivo: Determinar la frecuencia de alteraciones de la huella plantar en escolares. Determinar si existe relación entre el sobrepeso y la obesidad con la presencia de alteraciones de la huella plantar. Material y métodos: Estudio observacional, transversal y prospectivo. Se evaluaron 959 escolares de seis a 13 años de edad. Se registró peso, talla, índice de masa corporal para la edad. La huella plantar se catalogó en pie plano y pie cavo utilizando el índice del arco. Para el análisis y comparación estadística se utilizó el programa SPSS versión 24 con las pruebas χ2 y ANOVA. Resultados: Se revisaron 530 niños (55.3%) y 429 niñas (44.7%). La media de edad fue de 8.97 años. Se observaron 182 niños (19%) con alteración de la huella plantar, 42.3% con pie plano y 57.7% con pie cavo. Ninguno mostró sintomatología del pie. Ciento treinta y un niños tenían sobrepeso y 52 obesidad, sin influir en la presencia de alguna alteración de la huella plantar (p = 0.20). La relación de pie plano fue mayor en los hombres (2.5:1) y de pie cavo fue mayor en las mujeres (1.3:1). Conclusiones: En nuestro grupo de estudio se encontró mayor prevalencia del pie cavo en comparación con el pie plano. El peso corporal no influyó en las alteraciones de la huella plantar.

Abstract: Introduction: Alterations in the plantar footprint in the child are a cause for concern in parents. Objective: Determine the frequency of plantar footprint alterations in school children. Determine if there is a relationship between overweight and obesity with the presence of alterations of the plantar footprint. Material and methods: Observational, transversal and prospective study. 959 schoolchildren aged six to 13 were evaluated. Weight, size, body mass index for age were recorded. The plantar footprint was cataloged on flat foot and cavus foot using the arch index. For statistical analysis and comparison, the SPSS version 24 program was used with the χ2 and ANOVA tests. Results: 530 children (55.3%) and 429 girls (44.7%). The median age was 8.97 years. 182 children were found (19%) with alteration of the plantar footprint, 42.3% with flat foot and 57.7% with cavus foot. None of them had foot symptoms. 131 children were overweight and 52 obese, without influencing the presence of any alteration of the plantar footprint (p = 0.20). The flat-foot ratio was higher in men (2.5:1) and standing cavus major in women (1.3:1). Conclusions: In our study group we find a higher prevalence of the cavus foot compared to the flat foot. Body weight did not influence plantar footprint alterations.

Plasmatic adipocyte biomarkers and foot pain associated with flatfoot in schoolchildren with obesity

SUMMARY OBJECTIVE The aim of this study was to determine the potential association of foot pain and plasmatic adipocytes as physiological biomarkers of childhood obesity with the incidence of flatfoot in a cohort of Egyptian school children aged 6 -12 years. METHODS A total of 550 Egyptian schoolchildren (220 boys and 330 girls) aged 6-12 years were randomly invited to participate in this descriptive survey analysis. For all children, we assessed the diagnosis and severity of flatfoot as well as plasma adipocytes, as well as adiponectin, leptin, resistin, IL-6, and TNF-α, using the Dennis method and immunoassay techniques respectively. Foot pain was assessed by using a standard VAS of 100 mm and Faces Pain Scale, respectively. RESULTS Flat foot was predicted in 30.4% of school-age children, most of them showed a higher frequency of overweight (33.3%) and obesity (62.5%). Boys showed higher ranges of flat foot than girls. Foot pain significantly correlated with flat foot and obesity among the studied populations. In overweight-obese children, plasmatic adipocyte variables, as well as adiponectin, leptin, resistin, IL-6, TNF-α.; showed significant correlations with foot stance, especially in boys. Also, the studied adipocyte variables along with BMI, age, gender explained about~65% of the variance of flatfoot with pain among our school-age students. CONCLUSION Foot pain showed an association with flat foot and childhood obesity in 30.4% of school-age students (6-12 years). Foot pain was shown to correlate positively with the incidence of flat foot and changes in adiposity markers, as well as adiponectin, leptin, resistin, Il-6, TNF-α

MÉTODOS Um total de 550 escolares egípcios (220 meninos e 330 meninas) com idades entre 6 e 12 anos foram convidados aleatoriamente para participar desta análise descritiva. Para todas as crianças, diagnóstico e gravidade do flatfoot, bem como adipócitos plasmáticos; adiponectina, leptina, resistina, IL-6 e TNF-α; foram avaliados pelo método de Dennis e técnicas de imunoensaio, respectivamente. A dor no pé foi avaliada usando uma EVA padrão de 100 mm e a Faces Pain Scale, respectivamente. RESULTADOS O pé plano foi predito em 30,4% das crianças em idade escolar; a maioria apresentou maior frequência de sobrepeso (33,3%) e obesidade (62,5%). Os meninos apresentaram maiores faixas de pé plano do que as meninas. A dor no pé correlacionou-se significativamente com pé plano e obesidade entre as populações estudadas. Em crianças obesas com sobrepeso, variáveis adipocitárias plasmáticas; adiponectina, leptina, resistina, IL-6 e TNF-α; apresentaram correlação significativa com a postura do pé, em meninos e meninas. Além disso, as variáveis estudadas dos adipócitos, juntamente com o IMC, idade e sexo, explicaram cerca de 65% da variância do pé plano com a dor entre os nossos alunos em idade escolar. CONCLUSÃO A dor no pé mostrou associação com pé plano e obesidade infantil em 30,4% dos estudantes em idade escolar (6-12 anos). A dor no pé se correlacionou positivamente com a incidência de pé plano e a mudança nos marcadores de adiposidade; adiponectina, leptina, resistina, IL-6, TNF-α.

Alteraciones de la huella plantar en preescolares del Centro Infantil del Buen Vivir "Francisco Chiriboga" / Alterations of the footprint in preschoolers of the Center for Children of Good Living "Francisco Chiriboga"

La forma en que se manejan los problemas biomecánicos en niños constituye un tema contro-versial en el campo de la rehabilitación física. Se desarrolló un proceso investigativo con el objetivo de: describir la evolución de un grupo de pacientes pediátricos mayores de dos años diagnosticados con pie plano atendidos en consulta de fisioterapia en la ciudad de Riobamba; la que fue de tipo observacional descriptivo, de corte longitudinal, cuya población de estudio estuvo constituida por las fichas de control, evaluación y valoración de 30 niños mayores de 2 años que acudieron a consulta de fisioterapia acompañados de un tutor legal por presentar signos de alteraciones de la huella plantar (pie plano). Se observó un predominio de los pacien-tes con edades comprendidas entre cuatro y cinco años, para un 33 y 27% respectivamente. El 93% de los participantes presentó alteraciones de la huella plantar comprobada mediante medi-ción utilizando el plantígrafo, pero el 53% tuvo pie plano fisiológico. Luego de aplicados los ejercicios de Risser, los datos reflejaron una elevación de la cifra de huella plantar normal hasta el 33% y una disminución en el grado de afectación en el 35% de los niños diagnosticados. Los resultados de la recuperación fueron ratificados mediante el análisis del desgaste del calzado en los pacientes pediátricos en cuestión.

The way how biomechanical problems are handled is a controversial topic in the field of physi-cal rehabilitation. This is a research was carried out in order to describe the evolution of a group of pediatric patients over two years of age diagnosed with flat feet treated in a physiotherapy consultation in the city of Riobamba. This research was of observational descriptive type and longitudinal-cut. The study population consisted of the control, evaluation and assessment cards of 30 children over 2 years of age who attended a physiotherapy consultation accompanied by a legal guardian to show signs of alterations in the footprint (flat foot). A predominance of patients between four and five years of age with 33% and 27% respectively was observed. 93% of the participants presented alterations of the footprint checked by the means of a machine for measu-ring foot plant, but 53% had physiological flat feet. After applying the Risser exercises, the data was reflected in the figure of normal footprint up to 33%, and a decrease of affectation in 35% of the children diagnosed. The results of the recovery were confirmed through the analysis of footwear wear in the pediatric patients in question.

Introdução: O equilíbrio é essencial para o desempenho das atividades cotidianas e funcionalidade. É dependente da interação entre sistemas visual, vestibular e periférico, dos comandos do sistema nervoso central e respostas neuromusculares. Objetivo: Verificar a relação do estado nutricional e padrão de arco longitudinal medial (ALM) de pés com o equilíbrio de crianças entre 4 e 5 anos de idade. Métodos: Foram avaliadas 16 crianças, realizando avaliações antropométricas e análise do estado nutricional; depois, avaliação do ALM, com utilização de pedígrafo e classificação pelo índice de Cavanagh e Rodgers; por fim, avaliação do equilíbrio pela Escala de Equilíbrio Pediátrica (EEP). Resultados: O escore médio dos participantes na EEP foi de 53,56, variando entre 50 e 56. Com relação ao estado nutricional, 6,25% apresentaram obesidade, 18,75% risco de sobrepeso e o restante apresentou eutrofia. Para a análise do ALM constatou-se que 62,5% dos participantes apresentaram pé plano, 25% pé normal e 12,5% pé cavo. Conclusão: O estudo aponta que o sexo masculino, seguido da presença de pé plano, apresentou maior relação com o déficit de equilíbrio para a população de 4 a 5 anos. Já as crianças com sobrepeso e obesidade obtiveram escores típicos na EEP, retratando a necessidade de mais estudos. (AU)

Introduction: Balance is essential for the performance of everyday activities and functionality. It is dependent on the interaction between visual, vestibular and peripheral systems, central nervous system commands and neuromuscular responses. Objective: To relate the nutritional status and pattern of the medial longitudinal arch (MLA) of the feet with the balance of children between 4 and 5 years of age. Methods: We evaluated 16 children, performing anthropometric assessments and analysis of nutritional status; then MLA evaluation, using pedigree and classification by the Cavanagh and Rodgers index; finally, evaluation of balance by the Pediatric Balance Scale (PBS). Results: The mean score of the participants in the PBS was 53.56, ranging from 50 to 56. Regarding nutritional status, 6.25% presented obesity, 18.75% risk of overweight and the other presented eutrophy. For MLA analysis, 62.5% of the participants had flat feet, 25% normal feet and 12.5% foot caves. Conclusion: The study indicates that the male sex, followed by the presence of flat feet, presented a greater relation with the deficit of balance for the population of 4 to 5 years. On the other hand, overweight and obese children had typical scores on PBS, showing the need for further studies. (AU)

What is the Prognosis of Triple Arthrodesis in the Treatment of Adult Acquired Flatfoot Deformity (AAFD)? / Qual o prognóstico da artrodese tríplice quando utilizada no tratamento do pé plano adquirido do adulto (PPAA)?

Abstract Objective The present study aims to evaluate the ability of triple arthrodesis in eliminating the main complaints presented by patients with adult acquired flatfoot deformity (AAFD): 1) disabling hindfoot pain; 2) major deformities, such asmedial arch collapse, valgus, abduction, and supination. Methods A total of 17 patients (20 feet) with advanced AAFD who underwent surgical correction by triple arthrodesis were evaluated after a mean follow-up period of 43 months (range: 18-84 months). The average age of the patients at surgery was 62 years old (range: 38-79 years old). The visual analogue scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score were used to assess the final results. Results According to the VAS, the average residual pain was 3 points; the AOFAS hindfoot score points increased 23% after the surgery; and the correction of deformities was considered satisfactory in 10 out of 20 feet; partially satisfactory in 4 out of 20 feet; partially unsatisfactory in 5 out of 20 feet; and unsatisfactory in 1 out of 20 feet. Conclusion Despite the high index of bone fusion after triple arthrodesis, which is the gold standard treatment in advanced AAFD, the incomplete correction of major deformities and the persistence of residual pain contributed to a high disappointment rate of the patients with the surgical results.

Resumo Objetivo Avaliar a capacidade da artrodese tríplice de aliviar as principais queixas dos pacientes que apresentam pé plano adquirido do adulto (PPAA): 1) dor incapacitante localizada no médio e retropé; 2) deformidades marcadas pelo colapso do arco medial, valgo, abdução e supinação. Método Avaliamos 17 pacientes (20 pés) portadores de PPAA em estado avançado que foram submetidos à correção cirúrgica pela artrodese tríplice modelante. A média de idade dos pacientes no momento da cirurgia foi de 62 anos (variação de 38 a 79 anos), e o tempo médio de seguimento foi de 43 meses (variação de 18 a 84 meses). Utilizamos critérios clínicos empregando a escala visual analógica da dor (EVAD) e a escala funcional da American Orthopaedic Foot and Ankle Society (AOFAS, na sigla em inglês) do retropé para avaliar a eficácia da cirurgia. Resultados A dor residual mensurada pela EVAD foi de três pontos, em média. Observamos incremento médio de 23% nos valores da escala AOFAS do retropé após o tratamento cirúrgico. A correção das deformidades foi satisfatória em 10 de 20 pés; parcialmente satisfatória em 4 de 20 pés; parcialmente insatisfatória em 5 de 20 pés; e insatisfatória em 1 de 20 pés. Conclusão Apesar da artrodese tríplice modelante indicada no tratamento do PPAA em estágio avançado apresentar alto índice de consolidação óssea, a correção incompleta das deformidades pré-existentes e a persistência de dor residual contribuíram para a elevada taxa de decepção dos pacientes com o resultado da cirurgia.

Abstract Introduction: Some peculiar features of Down Syndrome (DS), such as ligament laxity, hypotonia, delay in gait acquisition, among others, may generate alterations in the distribution of plantar pressures, modifying the plantar support. Objective: To verify whether there are differences in the evaluation of plantar pressure distributions in standing posture between the measurement instruments (Baropodometer, SAPO, and Radiography). Method: This was a cross-sectional study, evaluating ten children with SD and ten children with normal development (ND), aged from two to five years old. Bio-photogrammetry, baropodometry, and foot radiography were used to assess the plantar pressure distribution. Kappa analysis was used to evaluate the agreement index between the different instruments. Results: Children with DS and ND had a higher prevalence of pronated feet in all three instruments, with poor to substantial agreement among the instruments. Conclusion: According to this study instruments, there was a greater prevalence of pronated feet in the two groups . Differences in the evaluation of the distribution of plantar pressures in the standing posture between the Baropodometer, SAPO, and radiography were observed. These instruments should be used in a complementary manner, as they propose to evaluate different aspects of the feet alignment.

Effects of the Short Foot Exercise With Neuromuscular Electrical Stimulation on Navicular Height in Flexible Flatfoot in Thailand: A Randomized Controlled Trial / 예방의학회지

OBJECTIVES: Flatfoot, or low medial longitudinal arch, contributes to back and lower extremity injuries and is caused by weak abductor hallucis (AbdH) muscles. The purpose of this study was to investigate the effects of short foot exercise (SFE) alone or with neuromuscular electrical stimulation (NMES) on navicular height, the cross-sectional area (CSA) of the AbdH muscle, and AbdH muscle activity in flexible flatfoot. METHODS: Thirty-six otherwise healthy people with flexible flatfoot were randomly assigned to a group that received SFE with placebo NMES treatment (the control group) or a group that received both SFE and NMES treatment (the experimental group). Each group received 4 weeks of treatment (SFE alone or SFE with NMES). Navicular height, the CSA of the AbdH muscle, and AbdH muscle activity were assessed before and after the intervention. RESULTS: No significant differences were found in navicular height or the CSA of the AbdH muscle between the control and experimental groups, while AbdH muscle activity showed a statistically significant difference between the groups (SFE=73.9±11.0% of maximal voluntary isometric contraction [MVIC]; SFE with NMES=81.4±8.3% of MVIC; p<0.05). Moreover, the CSA of the AbdH muscle showed a statistically significant increase after treatment in the SFE with NMES group (pre-treatment=218.6±53.2 mm²; post-treatment=256.9±70.5 mm²; p<0.05). CONCLUSIONS: SFE with NMES was more effective than SFE alone in increasing AbdH muscle activity. Therefore, SFE with NMES should be recommended to correct or prevent abnormalities in people with flexible flatfoot by a physiotherapist or medical care team.

Comparisons of Accuracy of Knee Joint Motion During Closed verse Open Kinetic Chain Tasks in Subjects with Flexible Flatfeet

PURPOSE: This study examined the effects of flexible flatfeet on the accuracy of knee joint motions in closed and open kinetic chain tasks. METHODS: Twenty-four healthy participants were recruited for this study. The subjects were divided into two groups using a navicular drop (ND) test: flexible flatfoot group (n=12, male: 6, aged 22.00±2.22 years) and age-matched control group (n=12, males: 6, aged 22.17±1.53 years). The accuracy of knee motion was measured quantitatively by tracing through the flexion and extension motion of the knee joints in the closed kinetic chain and the open kinetic chain. RESULTS: There was a significant difference in the accuracy index between the groups in closed kinetic chain task, but there was no significant difference in the open kinetic chain task. In addition, there was a significant difference in the accuracy index between the closed kinetic chain and the open kinetic chain task in the flexible flatfoot group. In addition, a significant negative correlation was observed between the ND and accuracy index in the closed kinematic chain task, but there was no significant relationship between the ND and accuracy index in the open kinematic chain task. CONCLUSION: Flexible flatfeet can affect the accuracy of the adjacent joints, such as the knee joint in the closed kinematic chain.

Bone and soft tissue combined with surgery for the treatment soft flatfoot combined with painful navicular bone / 中国骨伤

OBJECTIVE@#To explore short-term clinical effects of bone and soft tissue combined with surgery for the treatment of soft flatfoot accompanied with painful navicular bone.@*METHODS@#From May 2015 to August 2017, 16 patients (16 feet) with navicular bone soft flatfoot accompanied with painful navicular bone were treated with bone and soft tissues operation (gastrocnemius release, medial displacement calcaneal osteotomy, and excision of accessory navicular with reconstruction of posterior tibial tendon). Among them, there were 9 males (9 feet) and 7 females (7 feet), aged from 22 to 48 years old with an average of (32.0±3.4) years old. The duration of diseases ranged from 6 months to 5 years with an average of (2.4±1.7) years. The postoperative complications were observed, talocalcaneal angle, the first metatarsal horn of the talus, arch height, angle of inclination and calcaneal valgus before and after operation at 12 months were compared. VAS score and AOFAS score after operation at 12 months were applied to evaluate pain relief and function.@*RESULTS@#All patients were followed up for an average of (18.4±3.5) months(13~25 months). The incisions of patients were healed at grade A without wound infection, nonunion or delayed union, internal fixation fracture or loosening and other complications. Medial pain of foot was disappeared and motor ability was restored at 12 months after operation. Arch height, angle of inclination and the first metatarsal horn of the talus of lateral X-ray before operation and after operation at 12 months on weight-bearing foot were(21.51±1.20)°vs(31.01±1.62)°, (10.71±1.52)°vs(22.12±2.11)°, (15.61±1.41)°vs(5.10±1.20)°; talocalcaneal angle, the first metatarsal horn of the talus of AP X-ray before operation and after operation at 12 months on weight-bearing foot were (36.12±2.21) ° vs (22.12±2.61)°, (13.41±1.51)°vs(4.30±0.91)°; calcaneal valgus of axial X-ray before operation and after operation at 12 months on weight-bearing foot were (10.80±1.21)°vs(3.92±1.81)°; there were statistical difference in imaging indicators between preoperation and 12 months after operation. VAS score was significantly decreased from (6.21±2.31) before operation to (1.82±0.56) at 12 months after operation (=2.64, <0.05). AOFAS score was obviously increased from (51.2±5.6)before operation to (87.1±4.7)at 12 months after operation (=3.43, <0.05).@*CONCLUSIONS@#Bone and soft tissue operation (namely, gastrocnemius release, medial displacement calcaneal osteotomy, and excision of accessory navicular with reconstruction of posterior tibial tendon) could obviously relieve foot pain, improve foot appearance and function in patients with navicular bone soft flatfoot complicated with painful navicular bone, and has certain clinical efficacy.

Long-Term Effect of Rigid Foot Orthosis in Children Older Than Six Years With Flexible Flat Foot

OBJECTIVE: To evaluate the long-term effect of a custom-made rigid foot orthosis (RFO) in children older than 6 years with pes planus (flat foot). METHODS: Medical records of 42 children diagnosed with flexible pes planus who were fitted with RFOs based on the inverted technique and underwent more than four consecutive radiological studies were reviewed. Resting calcaneal stance position (RCSP), anteroposterior talocalcaneal angle, lateral talocalcaneal angle, lateral talometatarsal angle, and calcaneal pitch were initially measured in both feet to evaluate alignment. Followup clinical and radiological evaluations were then performed at 12–18, 24–30, 36–42, and ≥48 months after RFO application. Repeated measures analysis of variance was used to evaluate significant differences. RESULTS: Significant improvements in all radiological indicators and significant progression of RCSP toward the corrective direction were observed after RFO application relative to baseline measurements. CONCLUSION: According to our findings, RFO can induce significant improvements in calcaneus-related radiographic indices and subsequently improve talus-related radiologic indices.

Análisis biomecánico a través de simulación numérica de la ruptura del tendón del tibial posterior en el pie plano valgo: estudio en cadáver / Biomechanical analysis through numerical simulation of rupture of the tibial posterior tendon in valgus flat foot: a cadeveric study

Resumen: La insuficiencia del tendón del tibial posterior es la causa adquirida de dolor más común relacionada con la deformidad de pie plano valgo en adultos. El pie plano adquirido por el adulto es una deformidad sintomática muy dolorosa que resulta de un estiramiento gradual (atenuación) del tendón del tibial posterior, así como de los ligamentos que sostienen el arco de la planta del pie. El dolor progresivo en el pie plano adquirido por el adulto afecta cuatro veces más a las mujeres que a los hombres. Algunos factores que contribuyen a incrementar el riesgo del pie plano adquirido en el adulto son la diabetes, la hipertensión y la obesidad. Se piensa que la combinación de los eventos siguientes es la causa del pie plano adquirido por el adulto. La clasificación de Johnson Strom modificada por Mayerson lo evalúa en cuatro estadios. Este estudio se dividió en tres etapas: etapa 1: disección y análisis tridimensional del tendón, etapa 2: aplicación de herramientas de bioingeniería para determinar las causas de ruptura del tendón del tibial posterior y etapa 3: evaluación de 24 pacientes con enfermedad de pie plano valgo para describir la deformidad.

Abstract: The insufficiency of the posterior tibial tendon is the most common acquired cause of pain related to valgus flatfoot deformity in adults. The acquired flatfoot adult is a very painful symptomatic deformity resulting from a gradual stretching (attenuation) of the posterior tibial tendon and ligaments that support the arch of the foot. The progressive pain acquired flatfoot adult affects four times more women than men. Some factors that contribute to increased risk of acquired flatfoot in adults, are diabetes, hypertension and obesity. It is thought that the combination of the following events is the cause of acquired flatfoot adult. Johnson Strom classification modified by Mayerson evaluates in 4 stages. This study was divided into 3 stages: Stage 1: Dissection and three-dimensional analysis of the tendon, Step 2: Application of tools bioengineering to determine the causes of rupture of the tibial tendon: Stage 3: Evaluation of 24 patients with flatfoot disease valgus for describe the deformity.
