RESUMO

Mirror foot is a rare congenital anomaly on to the spectrum of complex foot polydactyly. It may occur in isolation or associated with other malformations or genetic syndromes. This is a subject little described in the literature, with few publications on its treatment. We herein report the case of a 4-year-old female patient who presented with a left foot with 8 fingers, without other associated deformities, whose complaints included the impossibility of wearing shoes and social stigma. Radiographically, eight metatarsi with their respective phalanges, five cuneiform bones, and absence of bone deformities in the hindfoot were verified. The surgical approach was chosen in order to promote functional and esthetic improvement, as well as a better adaptation to the use of closed shoes, according to the patient's and family's desire. A dorsal and plantar V incision was performed, with resection of three supranumerary rays, including three central metatarsi with their nine corresponding phalanges, two cuneiform bones, tendons and extra digital nerves, followed by suture of the intermetatarsal ligaments, preserving the fingers with normal appearance, decreasing the width of the foot, and maintaining proper support. The reduction was maintained through transmetatarsal fixation with Kirschner wires. The postoperative period went on with the use of a walking boot and zero load, without complications, with removal o the Kirschner wires and allowing load on the limb after twelve weeks.

RESUMO

Abstract Mirror foot is a rare congenital anomaly within the spectrum of complex polydactyly of the foot. It can occur alone or with other malformations or genetic syndromes. It is a little described topic in the literature, with few publications on its treatment. We report the case of a 4-year-old female patient who presented eight fingers on her left foot and no other associated deformities. Her complaints included the impossibility of wearing closed shoes and social stigma. Radiography revealed eight metatarsals with their respective phalanges, five cuneiform bones, and the absence of bone deformities in the hindfoot. We opted for a surgical approach aiming at functional and esthetic improvement, in addition to better adaptation to closed shoes, as desired by the patient and her family. We performed a dorsal and plantar "V" incision and resected three supernumerary rays, including three central metatarsals with their nine corresponding phalanges, two cuneiform bones, tendons, and excess digital nerves. Next, we sutured the intermetatarsal ligaments, preserving the fingers with a normal appearance, reducing the width of the foot, and preserving adequate support. Kirschner wires maintained the reduction by transmetatarsal fixation. During the postoperative period, the patient wore a boot splint with zero load with no complications. We removed the Kirschner wires and allowed load on the limb after 12 weeks.

Resumo O pé em espelho é uma anomalia congênita rara, pertencente ao espectro das polidactilias complexas dos pés. Pode ocorrer isoladamente ou associado a outras malformações ou síndromes genéticas. Trata-se de um tema pouco descrito na literatura, com escassas publicações acerca do seu tratamento. Relatamos o caso de uma paciente do sexo feminino, de 4 anos de idade, que apresentava pé esquerdo com 8 dedos, sem outras deformidades associadas, cuja queixa incluía impossibilidade do uso de calçados fechados e estigma social. Radiograficamente, verificou-se a presença de oito metatarsos com suas respectivas falanges, cinco ossos cuneiformes e ausência de deformidades ósseas no retropé. Optou-se pela abordagem cirúrgica visando uma melhoria funcional e estética, bem como melhor adaptação ao uso de calçados fechados, conforme desejo da paciente e de sua família. Foi realizada incisão em "V" dorsal e plantar com ressecção de três raios supranumerários, incluindo três metatarsos centrais com suas nove falanges correspondentes, dois ossos cuneiformes, tendões e nervos digitais excedentes, seguida da sutura dos ligamentos intermeta-tarsais, com preservação dos dedos com aparência normal, diminuição da largura do pé e manutenção do seu apoio adequado. A redução foi mantida por fixação transmetatarsal com fios de Kirschner. O pós-operatório seguiu com o uso de tala bota e carga zero, sem intercorrências; os fios de Kirschner foram retirados, e a carga no membro foi liberada após 12 semanas.

RESUMO

BACKGROUND: Alterations in vibration perception among children and adolescents with Charcot-Marie-Tooth disease might explain observed changes in foot posture. Therefore, this cross-sectional study compared the vibration perception of the lower limbs in youths with and without Charcot-Marie-Tooth disease and verified the cut-off value of the distal vibration perception for the Charcot-Marie-Tooth group. In addition, associations between dynamic plantar pressure, vibration perception and isometric muscle strength were investigated. METHODS: Participants aged 9-18 (Charcot-Marie-Tooth group n = 32; Typical group n = 32) had vibration perception measured by a 128-Hz graduated tuning fork. The static and dynamic foot posture were evaluated by the Foot Posture Index and pressure distribution measuring system, respectively. For the Charcot-Marie-Tooth group, a hand-held dynamometer evaluated the isometric muscle strength of the lower limbs. FINDINGS: Children with Charcot-Marie-Tooth disease presented impaired vibration perception at the distal phalanx of the hallux and head of the first metatarsal compared to their typically developing peers, while adolescents with Charcot-Marie-Tooth disease showed impairment in all the tested regions compared to their typically developing peers. The cut-off value for vibration perception for participants with Charcot-Marie-Tooth disease was 5.7, considering the original grade of the tuning-fork 128 Hz. Among the associations established for the Charcot-Marie-Tooth group, a greater vibration perception at the distal phalanx of the hallux was associated with a longer rearfoot contact time (ß = 31.02, p = 0.04). INTERPRETATION: These new findings may guide the clinical evaluation and rehabilitation treatment for children and adolescents with Charcot-Marie-Tooth disease.

RESUMO

Objective: The extrinsic muscles, such as the posterior tibialis and long flexor of the hallux and the intrinsic of the foot, are part of the active subsystem of the central system of the foot and play an essential role in the control of the medial longitudinal arch resulting from difficulty in contracting the muscle, neuromuscular electrostimulation (NMES) becomes a resource combined with strengthening and recommended for rehabilitation. T this work aims to evaluate the effectiveness of NMES associated with exercise in deforming the medial longitudinal arch. Methods: This is a randomized blind clinical trial. 60 asymptomatic participants were divided into three groups: NMES, exercise and control. The NMES and exercise group performed seven exercises for the intrinsic and extrinsic muscles twice a week for 6 weeks, and the NMES group used an NMES associated with five exercises. Navicular height and medial longitudinal arch angle were taken before and after the intervention period. Results: No statistically significant differences existed between groups for navicular height and medial longitudinal arch angle. Conclusion: NMES associated with exercise does not change the characteristics of the medial longitudinal arch in association with asymptomatic. Level of Evidence I; Randomized clinical trial.

Objetivo: Os músculos extrínsecos, como o tibial posterior e flexor longo do hálux e os intrínsecos do pé fazem parte do subsistema ativo do foot core system e exercem papel essencial no controle do arco longitudinal medial. Devido à dificuldade na contração desses músculos, a eletroestimulação neuromuscular (EENM) torna-se um recurso aliado ao fortalecimento e é recomendada para reabilitação. O objetivo desse trabalho é avaliar a eficácia da EENM associada ao exercício na deformação do arco longitudinal medial. Métodos: Este é um ensaio clínico randomizado cego. 60 participantes assintomáticos foram divididos em três grupos: EENM, exercício e controle. O grupo EENM e exercício realizaram sete exercícios para os músculos intrínsecos e extrínsecos duas vezes por semana por seis semanas, sendo o grupo EENM utilizou a EENM associada a cinco exercícios. A altura do navicular e o ângulo do arco longitudinal medial foram medidos antes e após o período de intervenção. Resultados: Não houve diferenças estatisticamente significativas entre os grupos para a altura do navicular e ângulo do arco longitudinal medial. Conclusão: A EENM associada ao exercício não altera as características do arco longitudinal medial em indivíduos assintomáticos. Nível de Evidência I; Estudo Clínico Randomizado.

RESUMO

El Hallux Varus Iatrogénico es una complicación de la cirugía correctiva del Hallux Valgus muy poco frecuente. El tratamiento incluye la intervención de los tejidos blandos, y óseos. El propósito de este trabajo es mostrar los resultados clínico-radiológicos del tratamiento quirúrgico del Hallux Varus Iatrogénico Flexible Severo empleando la combinación de técnicas de reconstrucción alternativas en una paciente femenina de 59 años de edad. Se realizó liberación medial de la capsula articular MTF y abductor, osteotomía de Chevron reverso, artrodesis interfalángica izquierda, transferencia tendinosa del extensor largo de Hallux hacia plantar con botón artesanal. De acuerdo a la Escala AOFAS aumentó de 30 a 90 puntos. Se logró la corrección estable de la deformidad en varo y la consolidación de la osteotomía. El Hallux Varus Iatrogénico es una complicación poco frecuente considerada una deformidad mal tolerada, con pocos casos reportados y pocos reportes. Se debe hacer un enfoque de tratamiento paso a paso para abordar todos los elementos involucrados en el Hallux Varus iatrogénico. La corrección quirúrgica del Hallux Varus iatrogénico severo con técnicas de reconstrucción no convencionales tipo Chevron reverso y transferencia tendinosa con botón plantar, es una excelente opción terapéutica de acuerdo a los resultados obtenidos en este caso(AU)

Iatrogenic Hallux Varus is a very rare complication of Hallux Valgus corrective surgery. The treatment includes the intervention of soft tissues and bones. The purpose of this paper is to show the clinical-radiological results of the surgical treatment of Severe Flexible Iatrogenic Hallux Varus using the combination of alternative reconstruction techniques in a 59-year-old female patient. Medial release of the MTF and abductor joint capsule, reverse Chevron osteotomy, left interphalangeal arthrodesis, tendon transfer of the long extensor of Hallux to plantar with artisanal button was performed. According to the AOFAS Scale, it increased from 30 to 90 points. Stable correction of the varus deformity and consolidation of the osteotomy were achieved. Iatrogenic Hallux Varus is a rare complication considered a poorly tolerated deformity, with few reported cases and few reports. A step-by-step treatment approach must be taken to address all the elements involved in iatrogenic Hallux Varus. Surgical correction of severe iatrogenic Hallux Varus with unconventional reconstruction techniques such as reverse Chevron and plantar button tendon transfer is an excellent therapeutic option according to the results obtained in this case(AU)

RESUMO

Congenital clubfoot is one of the most common congenital deformities of the lower limbs, with an estimated incidence of 1 for every 1,000 live births. Its treatment is controversial, and currently the Ponseti method has been widespread, showing promising results and decreasing the need for extensive surgical releases, as was usually done until the introduction of the technique. Currently used in approximately 55 countries, the method has changes and scopes that vary according to the society in which it is applied, with the results and peculiarities of the method molded according to the sample studied. Objective: To evaluate the clinical outcome of clubfoot treatment using the Ponseti method under local conditions. Methods: The clinical evaluation will include a descriptive analysis of the sample, as well as radiographic evaluation and family satisfaction with the treatment. Results: In total, 46% of the patients had good results and no family was dissatisfied with the treatment results. No statistically relevant relationships were found between the studied variables. Conclusion: The results are good and generally similar to those in the literature. Our epidemiological data generally agree with those reported by other authors. Level of Evidence IV, Case Series.

RESUMO

An analysis was carried out in relation to the adverse effects produced by the use of inadequately made footwear in patients with flexible flat feet in pediatric ages; we carried out an anatomical-functional reminder of the foot as a basic structure for standing and walking. The functional adaptability of the feet was valued in those populations with the habit of walking barefoot, also making a description of the basic characteristics that a properly made footwear must have. We address the different therapeutic approaches and their behavior over time. We highlight the widespread use in our society of inappropriate footwear, mainly of the flip-flop type, and its negative influence on the feet of those children with flexible flat feet and valgus of the ankle.

RESUMO

Objective To describe the profile of the patients and the results obtained with the use of an external fixator for metatarsal lengthening in brachymetatarsia. Methods A retrospective analysis of the medical records of patients with brachymetatarsia treated between January 2018 and April 2020 was performed. During this period, eight feet of six patients were operated on. Frequencies were estimated according to demographic and surgical aspects. Results All patients (100%; n = 6) were female, with a mean age of 28 years old, ranging from 15 to 48 years old, and were motivated to seek the orthopedic service due to aesthetic deformity. The deformity was bilateral in two patients and unilateral in four patients. The average lengthening time was 22 days ( ± 7.15, 95% confidence interval [CI]: 19.04-26.81). The lengthening speed was 0.5 mm/day, and the average total length of the lengthening was 11.46 mm ( ± 3.57; 95%CI: 9.52-13.40). Half of the patients (50%; n = 3) had local infection of the pins and were treated with antibiotics, and the others did not report any postsurgical complications. All patients denied pain or calluses after the surgical procedure and reported satisfaction with the results. Conclusion All patients were female and sought surgery for brachymetatarsia for aesthetic reasons. Osteogenic distraction at a rate of 0.5 mm/day resulted in successful lengthening of the metatarsal, with a low frequency of complications, good clinical outcomes, and high patient satisfaction.

RESUMO

Congenital clubfoot is one of the most common deformities at birth. The inadequacy or absence of treatment causes serious limitations for people with this condition. The initial treatment using the Ponseti method ensures functional results superior to other treatment modalities previously proposed. However, recurrences and neglected feet are still a challenge today. An understanding of the pathophysiology of the disease, as well as of the anatomy and local biomechanics and a thorough clinical and radiological evaluation of patients are essential to understanding the limits of the method and choosing the best treatment.

RESUMO

OBJECTIVE: The medial longitudinal arch is the main structure of load bearing and shock absorption of the foot. The evaluation of medial longitudinal arch, such as the navicular height, the medial longitudinal arch angle and the Feiss line should be performed with the subtalar joint in the neutral and relaxed position. Our study analyzed the correlation between the measurements of the subtalar joint in neutral and relaxed positions during the evaluation tests of the medial longitudinal arch. METHODS: This is a cross-sectional study, in which 51 healthy volunteers (102 feet; 36 women; 28 ± 5 years, 1.66 ± 0.10 m; 24.5 ± 4.5 kg/m2) had their navicular height, medial longitudinal arch angle and Feiss line measured in the neutral and relaxed positions. The correlation between the measures was evaluated using Pearson's test. RESULTS: A strong correlation of the 102 feet Feiss line measurements between neutral and relaxed positions (r = 0.81) was observed, and a moderate correlation between the medial longitudinal arch angle (r = 0.78) and between navicular height in neutral and relaxed positions (r = 0.76). CONCLUSION: The measurements of the longitudinal medial arch between the neutral and relaxed positions are strongly correlated. Therefore, it is not necessary to measure the medial longitudinal arch in both neutral and relaxed positions. Level of Evidence II, Diagnostic Studies - Investigating a diagnostic test.

OBJETIVO: O arco longitudinal medial é a estrutura principal para suporte de carga e absorção de impacto no pé. Medidas para avaliação do arco longitudinal medial, como a altura navicular, o ângulo do arco longitudinal medial e a linha de Feiss devem ser realizadas com a articulação subtalar na posição neutra e relaxada. Este estudo analisou a correlação entre as medidas da articulação subtalar em posições neutra e relaxada durante os testes de avaliação do arco longitudinal medial. MÉTODOS: Neste estudo transversal, 51 voluntários saudáveis (102 pés; 36 mulheres; 28 ± 5 anos, 1,66 ± 0,10 m; 24,5 ± 4,5 kg/m2) tiveram altura navicular, ângulo do arco longitudinal medial e linha de Feiss medida nas posições neutra e relaxada. A correlação entre eles foi avaliada pelo teste de Pearson. RESULTADOS: Houve uma correlação muito forte das medidas de linha de Feiss de 102 pés entre a posição neutra e relaxada (r = 0,81) e uma correlação moderada entre o ângulo do arco longitudinal medial (r = 0,78) e altura navicular nas posições neutra e relaxada (r = 0,76). CONCLUSÃO: As medidas do arco medial longitudinal entre as posições neutra e relaxada estão fortemente correlacionadas. Não é necessário, portanto, medir o arco longitudinal medial nas posições neutra e relaxada. Nível de Evidência II, Estudos diagnósticos - Investigação de um exame para diagnóstico.

RESUMO

ABSTRACT BACKGROUND: Frailty is a condition that can increase the risk of falls. In addition, foot disorders can negatively influence elderly people, thus affecting their condition of frailty. OBJECTIVE: To determine whether foot pain can influence a greater degree of frailty. DESIGN AND SETTING: Cross-sectional descriptive study conducted at the University of Valencia, Valencia, Spain. METHODS: A sample older than 60 years (n = 52), including 26 healthy subjects and 26 foot pain patients, was recruited. Frailty disability was measured using the 5-Frailty scale and the Edmonton Frailty scale (EFS). RESULTS: There were statistically significant differences in the total EFS score and in most of its subscales, according to the Mann-Whitney U test (P < 0.05). In addition, foot pain patients presented worse scores (higher 5-Frailty scores) than did healthy patients, regarding matched-paired subjects (lower EFS scores). With regard to the rest of the measurements, there were no statistically significant differences (P > 0.05). The highest scores (P < 0.001) were for fatigue on the 5-Frailty scale and the EFS, and for the subscale of independence function in EFS. CONCLUSIONS: These elderly patients presented impairment relating to ambulation and total 5-Frailty score, which seemed to be linked to the presence of frailty syndrome and foot disorders.

Results: A strong correlation of the 102 feet Feiss line measurements between neutral and relaxed positions (r = 0.81) was observed, and a moderate correlation between the medial longitudinal arch angle (r = 0.78) and between navicular height in neutral and relaxed positions (r = 0.76). Conclusion: The measurements of the longitudinal medial arch between the neutral and relaxed positions are strongly correlated. Therefore, it is not necessary to measure the medial longitudinal arch in both neutral and relaxed positions. Level of Evidence II, Diagnostic Studies - Investigating a diagnostic test.

RESUMO Objetivo: O arco longitudinal medial é a estrutura principal para suporte de carga e absorção de impacto no pé. Medidas para avaliação do arco longitudinal medial, como a altura navicular, o ângulo do arco longitudinal medial e a linha de Feiss devem ser realizadas com a articulação subtalar na posição neutra e relaxada. Este estudo analisou a correlação entre as medidas da articulação subtalar em posições neutra e relaxada durante os testes de avaliação do arco longitudinal medial. Métodos: Neste estudo transversal, 51 voluntários saudáveis (102 pés; 36 mulheres; 28 ± 5 anos, 1,66 ± 0,10 m; 24,5 ± 4,5 kg/m2) tiveram altura navicular, ângulo do arco longitudinal medial e linha de Feiss medida nas posições neutra e relaxada. A correlação entre eles foi avaliada pelo teste de Pearson. Resultados: Houve uma correlação muito forte das medidas de linha de Feiss de 102 pés entre a posição neutra e relaxada (r = 0,81) e uma correlação moderada entre o ângulo do arco longitudinal medial (r = 0,78) e altura navicular nas posições neutra e relaxada (r = 0,76). Conclusão: As medidas do arco medial longitudinal entre as posições neutra e relaxada estão fortemente correlacionadas. Não é necessário, portanto, medir o arco longitudinal medial nas posições neutra e relaxada. Nível de Evidência II, Estudos diagnósticos - Investigação de um exame para diagnóstico.

RESUMO

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.

RESUMO

Las alteraciones en los pies son una consulta frecuente en ortopedia pediátrica. La gran mayoría corresponde a condiciones que no constituyen patología y habitualmente no necesitan tratamiento, como el pie plano flexible. Por otro lado, existen deformidades patológicas que necesitarán un adecuado estudio y tratamiento. Según su morfología podemos clasificarlas en cavo-varo, plano-valgo y misceláneas. Su origen puede ser congénito o adquirido y de diversas etiologías, destacando el pie bot, metatarso varo, hallux valgus juvenil y aquellas secundarias a enfermedades neuromusculares, entre otras. Conocer la historia natural de cada deformidad nos permite decidir el momento más adecuado para cada tratamiento. Los antecedentes mórbidos y perinatales del paciente son muy importantes, así como el nivel de actividad física y/o deportiva. El examen físico debe incluir observar la marcha, extremidades inferiores, tobillo y pie. En el pie se debe analizar cada segmento por separado (antepié, mediopié y retropié) y las articulaciones respectivas. Es muy importante distinguir entre deformidades rígidas y flexibles. El tratamiento incluye la observación (condiciones benignas y autolimitadas), calzado adecuado, insertos plantares, órtesis, yesos correctores, cirugía de partes blandas y cirugía ósea; todo complementado por un adecuado programa de rehabilitación funcional y deportivo.

Foot disorders are a frequent cause of consultation in pediatric orthopaedics. The vast majority correspond to conditions that don't constitute pathology and usually don ́t need treatment, such as flexible flat foot. On the other hand, there are pathological deformities that will require a proper study and treatment. According to their morphology we can classify them in cavo-varus, plano-valgus and miscellaneous. Its origin can be congenital or acquired and due to various etiologies, highlighting clubfoot, metatarsus adductus, juvenile hallux valgus and those secondary to neuromuscular diseases, among others. Knowing the natural history of each deformity allows us to decide the most appropriate time for each treatment. Patient's morbility and perinatal history is very important, as well as their level of physical and/or sports activity. Physical exam should include gait obsevation, lower limbs, ankles and feet. In the foot, each segment should be analyzed separately (forefoot, midfoot and hindfoot) and their joints. It ́s very important to distinguish between rigid and flexible deformities. Treatments include observation (benign and self-limited conditions), adequate footwear, insoles, orthosis, corrective casting, soft tissue surgery and bone surgery; all complemented by an adequate functional and sports rehabilitation programs

RESUMO

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 as medial 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.
