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

Resumen Objetivo: Analizar los resultados de la técnica quirúrgica de colocación de clavillos Kirschner forma lateral versus cruzada en el manejo de las fracturas supracondíleas de húmero en pacientes pediátricos. Metodología: Se captaron a todos los pacientes con fractura supracondílea humeral en edad pediátrica que requirieron intervención quirúrgica, y posteriormente fueron evaluados a las 24 horas y 6 meses posterior al tratamiento quirúrgico para observar y comparar las diferencias entre cada técnica quirúrgica utilizada, tomando en cuenta las complicaciones agudas y tardías que se presentaron mediante un análisis con la prueba de Mann-Whitney. Resultados: Para el presente estudios se evaluaron 44 pacientes pediátricos de los cuales 70% eran hombres y 30% mujeres, en quienes se presentaron complicaciones nerviosas y angulares sin importancia significativa alguna con el sexo y edades de los pacientes, siendo la afección del nervio cubital la de mayor frecuencia con 33% en la colocación de forma cruzada. Al realizar la comparativa con discriminación de variables se obtiene que la colocación de forma lateral presenta menos complicaciones posquirúrgicas tempranas y tardías y que tales no se deben al azar. Limitaciones o implicaciones: En el presente estudio no se incluyó el tipo de daño mecánico que provoca este tipo de fractura, ni se consideró el ángulo de Baumann. Otra limitación inherente en la población pediátrica es la habilidad del explorador para detectar un déficit neurológico, especialmente en pacientes de edad temprana dado a que los reportes de una exploración física siempre son subjetivos. Además, dada la limitación en cuanto a los detalles del mecanismo específico de daño, se puede subestimar el número de daños provocados por mecanismos de alta energía. Originalidad y valor: Su importancia radica en que ambas técnicas quirúrgicas fueron realizadas por los mismos cirujanos y que se trata de un estudio en población mexicana, siendo un aporte para la literatura de este país. Conclusión: Ambas técnicas quirúrgicas presentan resultados posquirúrgicos con casos de lesión nerviosa, deformidad angular, dolor y edema persistente, pero la que los presenta en menor frecuencia es la técnica de colocación de clavillos Kirschner en forma lateral, además de causar una significancia estadística en cuanto a la disminución de presentar cubito valgo en el seguimiento tardío de los pacientes.

Abstract: Objective: To analyze the results of the surgical technique placement of Kirschner pins lateral versus crossed in the management of supracondylar fractures of the humerus in pediatric patients. Methodology: All pediatric patients with humeral supracondylar fracture who required surgical intervention and were subsequently evaluated 24 hours and 6 months after surgical treatment to observe and compare the differences between each patient. surgical technique used. Taking into account the acute and late complications that occurred, through an analysis with the Mann-Whitney test. Results: For the present studies, 44 pediatric patients were evaluated, of whom 70% were men and 30% women, in whom nerve and angular complications presented without any significant importance with the sex and age of the patients, with ulnar nerve involvement being the most frequent with 33% in cross placement. When carrying out the comparison with discrimination of variables, it is obtained that the placement laterally presents fewer early and late post-surgical complications and that such are not due to chance. Or the present study, it is considered that a placement of Kirschner pins laterally regardless of the member, age, gender or classification; leads to better post-surgical results. Limitations or implications: In the present study, the type of mechanical damage that causes this type of fracture was not included, nor was the Baumann angle considered. Another limitation inherent in the pediatric population is the ability of the examiner to detect a neurological deficit, especially in young patients since reports of a physical examination are always subjective. Furthermore, given the limited details of the specific damage mechanism, the number of damages caused by high-energy mechanisms may be underestimated. Originality or value: Its importance lies in the fact that both surgical techniques were performed by the same surgeons and that it is a study in the mexican population, being a contribution to the literature of this country. Findings or conclusions: Both surgical techniques present post-surgical results with cases of nerve injury, angular deformity, pain and persistent edema, but the one that presents them less frequently in the technique of placement of Kirschner pins laterally, in addition to causing statistical significance in terms of the decrease of presenting cubitus valgus in the late follow-up of the patients.

RESUMO

Objective To compare the use of cannulated screws and smooth Kirschner wires in terms of reducing the presence of exuberant callus and complications in pediatric displaced fractures of the lateral humeral condyle. Methods An analytical cross-sectional study of consecutive cases was conducted from May to October 2021 with 30 children with displaced external humeral condyle fractures. The functional results regarding pain and range of motion were stratified using the Dhillon grading system. Results A total of 19 patients underwent Kirschner wire fixation, and 11 underwent cannulated screw fixation. Closed fixation was performed in 14 cases (47%), and open fixation, in 16 (53%). Of the cases included, there was no loss to follow-up. Te sample was composed of 21 (70%) male patients, and the age ranged from 5 to 15 years, with a mean of 6.96 years. The most frequent cause of fracture was fall from height (50%), which was related to greater displacement on baseline radiographs. Complications that were not related to the reduction approach or the implant used were observed in 12 (40%) cases. Conclusion The present study shows no benefits in relation to the use of smooth pins or cannulated screws to reduce the presence of exuberant callus in the consolidation of the fracture. We see that the complications that arise are related to the severity of the injury, and benefits cannot be identified in the choice of one implant over another. We could see that the Weiss classification helps to define the behavior in favor of open or closed reduction without interfering in kindness of the smooth pin or the cannulated screw for fracture fixation.

Resumo Objetivo Comparar o uso de parafusos canulados e de fios de Kirschner lisos em termos da redução da presença de calo exuberante e de complicações em fraturas pediátricas deslocadas do côndilo lateral do úmero. Métodos Um estudo analítico transversal de casos consecutivos foi realizado de maio a outubro de 2021 com 30 crianças com fraturas deslocadas de côndilo umeral externo. Os resultados funcionais para dor e amplitude de movimento foram estratificados utilizando o sistema de classificação Dhillon. Resultados Ao todo, 19 pacientes foram submetidos à fixação de fio Kirschner, e 11 à fixação de parafusos canulados. A fixação realizada foi fechada em 14 casos (47%) e aberta em 16 (53%). Dos casos incluídos, não houve perda no acompanhamento. A amostra continha 21 (70%) pacientes do sexo masculino, e a idade variou de 5 a 15 anos, com média de 6,96 anos. A causa mais frequente de fratura foi queda de altura (50%), e esteve relacionada ao maior deslocamento nas radiografias da linha de base. Complicações que não estavam relacionadas à abordagem de redução ou ao implante utilizado foram observadas em 12 (40%) casos. Conclusão Este estudo não mostra benefícios em relação ao uso de pinos lisos ou de parafusos canulados para reduzir a presença de calo exuberante na consolidação da fratura. Vemos que as complicações que surgem estão relacionadas à gravidade da lesão, e não é possível identificar benefícios na escolha de um implante ou outro. Pudemos ver que a classificação de Weiss ajuda a definir o comportamento em favor da redução aberta ou fechada sem dar preferência ao pino liso ou ao parafuso canulado para a fixação da fratura.

Introduction: Supracondylar humeral fractures in children are frequent injuries. The treatment of these injuries is generally a surgical one through closed or open reduction and placement of Kirschner wires. Objective: To update and provide information on Kirschner wire fixation in pediatric patients with supracondylar humeral fractures. Methods: The search and analysis of the information was carried out in a period of 61 days (September 1st to October 31st, 2022) and the following words were used: pediatric supracondylar humeral fractures AND pinning, pinning configuration, pinning loosening AND pediatric supracondylar fractures. To focus the search, the Boolean OR or AND operators were used as appropriate. Based on the information obtained, a bibliographic review of a total of 211 articles published in the PubMed, Hinari, SciELO and Medline databases was carried out using the search reference manager EndNote. Of which 38 selected citations were used to conduct the review, all from the last five years. Results: References are made to the types of Kirschner wire used for this kind of fracture fixation. The most widely used wire configurations are mentioned, such as two lateral wires followed by crossed fixation. The most frequent errors in the placement of the wires are exposed, in addition to the complications related to this surgical procedure. Conclusions: In general, supracondylar humeral fractures in children require surgical management. The closed reduction through the placement of percutaneous Kirschner wires, require specific technical knowledge.

RESUMO

Introduction: Fractures of the distal third of the forearm are common in the pediatric population. Conservative treatment of an ipsilateral fracture of the distal ulna metaphysis is one of the risk factors for loss of reduction. Percutaneous fixation of the fracture with K-wires is recommended. This study aims to evaluate the outcome of percutaneous fixation of both bones performed as the primary treatment. Materials and Methods: A randomized, open, prospective, clinical trial was conducted, including skeletally immature patients who underwent surgery for fractures of the distal radius and ulna. They were randomized into two groups, one with fixation only of the radius fracture and the other with fixation of both the radius and the ulna fractures, and they were followed clinically and radiologically for up to 12 weeks postoperatively. Results: Sixteen children were selected. In the intraoperative period, fluoroscopy was activated for a longer time when fixing the ulna (p = 0.011) and the surgical time was longer in this group (p = 0.014). In the postoperative evaluations, the group whose surgery involved the fixation of both bones had a lower postoperative pain score (p <0.001) and less time away from school (p <0.001). Conclusions: In this study, postoperative pain and absence from school were both less when fixation of the radius and ulna was performed. Evidence Level II; Randomized Controlled Study.

Introdução: As fraturas do terço distal do antebraço são comuns na população pediátrica. O tratamento conservador da fratura ipsilateral da metáfise distal da ulna é um dos fatores de risco para a perda da redução. Recomenda-se a fixação percutânea da fratura com fios K. Este estudo tem como objetivo avaliar o resultado da fixação percutânea de ambos os ossos realizada como tratamento primário. Materiais e Métodos: Foi realizado um estudo clínico randomizado, aberto e prospectivo, que incluiu pacientes com esqueleto imaturo que foram submetidos à cirurgia para fraturas da parte distal do rádio e a ulna. Os participantes foram randomizados em dois grupos, um com fixação apenas da fratura do rádio e outro com fixação das fraturas do rádio e da ulna, e foram acompanhados clínica e radiologicamente por até 12 semanas de pós-operatório. Resultados: Dezesseis crianças foram selecionadas. No intraoperatório, a fluoroscopia foi ativada por mais tempo na fixação da ulna (p = 0,011) e o tempo cirúrgico foi maior nesse grupo (p = 0,014). Nas avaliações pós-operatórias, o grupo cuja cirurgia envolveu a fixação de ambos os ossos teve escore de dor menor depois da cirurgia (p < 0,001) e menos tempo de afastamento da escola (p < 0,001). Conclusões: Neste estudo, a dor pós-operatória e o afastamento da escola foram menores quando se realizou fixação do rádio e da ulna. Nível de Evidência II; Estudo randomizado controlado.

RESUMO

Introducción: Las lesiones traumáticas del codo son muy frecuentes, sobre todo en niños y adolescentes. Algunas de ellas son de difícil tratamiento y se asocian a complicaciones. De ellas, las fracturas supracondíleas del húmero son una de las más frecuentes. Objetivo: Describir las características epidemiológicas de un grupo de pacientes con esta enfermedad traumática. Métodos: Se realizó un estudio observacional descriptivo en 56 pacientes menores de 18 años atendidos en el Hospital Pediátrico Provincial Dr. Eduardo Agramonte Piña de la provincia Camagüey desde el primero de enero de 2018 al 31 de diciembre de 2021 con un total de 48 meses. Resultados: La razón sexo masculino-femenino de los 56 pacientes fue de 3,3 a 1, codo izquierdo-derecho de 1,9 a 1 y zona rural urbana de 2,2 a 1. El promedio de edades en general fue de 7,5 años. La estadía hospitalaria promedio fue de 4,8 días. El mecanismo de extensión fue el hallazgo más frecuente, así como las fracturas grado III. Los meses de enero y julio en conjunto con los días del jueves, viernes y domingo son los que presentan la mayor cantidad de pacientes. La reducción cerrada y fijación percutánea con alambres de Kirschner fue el método más empleado en esta enfermedad traumática. Conclusiones: Las fracturas supracondíleas del humero en el niño son más frecuentes en el sexo masculino y el codo izquierdo. El promedio de edades en el sexo masculino es mayor que en el femenino. Las zonas rurales aportan la mayor cantidad de pacientes. El tratamiento más empleado es el quirúrgico y las complicaciones inmediatas son infrecuentes.

Introduction: Traumatic injuries of the elbow are very frequent, some of them are difficult to treat and are associated with complications, of which supracondylar fractures of the humerus are one of the most frequent. Objetive: To describe the epidemiological behavior of a group of patients with this traumatic disease. Methods: A descriptive observational study was carried out in patients treated at the Dr. Eduardo Agramonte Piña Provincial Pediatric Hospital in the city of Camagüey from January 1st, 2018 to December 31st, 2021 with a total of 48 months. Results: the male-female sex ratio of the 56 patients was 3.3 to 1, the left-right elbow was 1.9 to 1, and the urban rural area was 2.2 to 1. The average age in general was 7.5 years. The average hospital stay was 4.8 days. The extension mechanism was the most frequent finding, as well as grade III fractures. The months of January and July together with the days of Thursday, Friday and Sunday are the ones with the largest number of patients. Closed reduction and percutaneous fixation with Kirschner wires was the most used method in this traumatic entity. Conclusions: Supracondylar fractures of the humerus in children are more frequent in males and in the left elbow. The average age of males is higher than that of females. Rural areas provide the largest number of patients. The most used treatment is surgery and immediate complications are infrequent.

RESUMO

OBJECTIVE: To compare the outcomes of the fixation of complete and displaced supracondylar humeral fractures in children with two different Kirschner wire configurations. METHODS: The type of fixation was randomized to either crossed (19 cases), or two divergent lateral Kirschner wires (24 cases). The comparison was made six months later between the two treated groups and each group with the non-fractured elbow (clinical alignment, range of motion, Baumann angle, and lateral humeral capitellar angle). RESULTS: 43 children were evaluated (65% boys) with a mean age of six years and five months. The carrying angle (p = 0.94), extension (p = 0.89), and the Flynn´s criteria (p = 0.56) were similar between the groups. The flexion was slightly smaller for the crossed wire group (p = 0.04), but similar to the uninjured side. The Baumann angle was not different between the two fixations (p = 0.79) and the contralateral side (p = 0.1). The lateral humeral capitellar angle was slightly greater for the lateral pinning (p = 0.08), but with no difference with the uninjured elbow (p = 0.62). No iatrogenic injuries were observed. CONCLUSION: Both fixations presented similar outcomes that did not significantly affect the carrying angle in relation to the non-fractured side. Level of evidence II, Therapeutic study - Investigating the results of treatment.

OBJETIVO: Comparar os resultados da fixação das fraturas supracondilianas completas e desviadas do úmero de crianças com dois tipos de configuração de fios de Kirschner. MÉTODO: O tipo de fixação foi aleatorizado para fixação com dois fios de Kirchner cruzados ou laterais divergentes. Depois de seis meses foi feita a comparação entre os dois grupos fixados entre si e cada um deles com o lado não fraturado do mesmo paciente (alinhamento clínico, arco de movimento, critérios de Flynn, ângulos de Baumann e capituloumeral). RESULTADOS: Participaram do estudo 43 crianças (65% meninos), com idade média de seis anos e cinco meses. A extensão (p = 0,89), o ângulo de carregamento (p = 0,94) e os critérios de Flynn (p = 0,56) foram semelhantes entre os dois grupos, sem ocorrência de lesões iatrogênicas. A flexão foi discretamente menor no grupo com fios cruzados (p = 0,04), mas próximo do cotovelo normal. O ângulo de Baumann não apresentou diferença entre as duas fixações (p = 0,79), bem como com o lado não fraturado (p = 0,01). O ângulo capituloumeral foi ligeiramente maior (p = 0,08) nos fios laterais, mas sem diferença em relação lado normal (p = 0,62). CONCLUSÃO: As duas fixações apresentaram resultados similares e não alteraram significativamente o ângulo frontal do cotovelo em relação ao lado não fraturado. Nível de evidência II, Estudo terapêutico - Investigação dos resultados do tratamento.
