Investigation of the relationship between foot deformities and radiographic measurements of the talus and calcaneus / Investigación de la relación entre las deformidades del pie y las mediciones radiográficas del talo y del calcáneo

SUMMARY: The weight of the body is transmitted to the foot through the subtalar joint and talus. Considering the important location of the talus and calcaneus, the morphological structures of these bones may affect the biomechanics of the subtalar joint. At the same time, the morphological structure of these bones is important in some common foot deformities. We aimed to investigate whether the various measurements of the talus and calcaneus are associated with different foot deformities in this study. In this study, radiography images of 158 (72 male and 86 female) patients within the mean age of 44 years were retrospectively examined. Eleven different measurements of the talus and calcaneus were obtained from the lateral and antero-posterior radiographs of the patients. A total of 158 patient's routine clinic radiographs were retrospectively assessed, which have calcaneal spur (n=63), hallux valgus (n=32) and control group (n=63). We determined that the body height of the calcaneus, maximum width of the head of the talus, minimum anterior width of the calcaneus were significantly different between calcaneal spur group and control group. Maximum length fibular malleolar facet of the talus was significantly different between age groups. And we determined that the calcaneal index was significantly different between hallux valgus group and control groups. Also all measurements were significantly different between males and females. As a result, some measurements that significantly determine the morphology of the talus and calcaneus were found to be significant between deformity groups and control groups. We think that our study will contribute to the literature as it is the first study in which the measurements obtained from the radiographic images of the talus and calcaneus are associated with foot deformities.

El peso del cuerpo se transmite al pie a través de la articulación subtalar y el talo. Teniendo en cuenta la importante ubicación del talo y el calcáneo, las estructuras morfológicas de estos huesos pueden afectar la biomecánica de la articulación subtalar. Al mismo tiempo, la estructura morfológica de estos huesos es importante en algunas deformidades comunes del pie. Nuestro objetivo fue investigar si las diversas medidas del talo y el calcáneo están asociadas con diferentes deformidades del pie en este estudio. Se examinaron retrospectivamente imágenes radiográficas de 158 pacientes (72 hombres y 86 mujeres) con una edad promedio de 44 años. Se obtuvieron once medidas diferentes del talo y el calcáneo a partir de las radiografías lateral y anteroposterior de los pacientes. Se evaluaron retrospectivamente un total de 158 radiografías clínicas de rutina de los pacientes, los cuales tenían espolón de calcáneo (n=63), hallux valgus (n=32) y grupo control (n=63). Determinamos que la altura del cuerpo del calcáneo, el ancho máximo de la cabeza del talo, el ancho anterior mínimo del calcáneo fueron significativamente diferentes entre el grupo con espolón calcáneo y el grupo control. La longitud máxima de la faceta maleolar fíbular del talo era significativamente diferente entre los grupos de edad. También determinamos que el índice calcáneo fue significativamente diferente entre el grupo de hallux valgus y los grupos controles. Además, todas las medidas fueron significativamente diferentes entre hombres y mujeres. Como resultado, algunas medidas que determinan la morfología del talo y el calcáneo resultaron significativas entre los grupos de deformidad y los grupos controles. Estimamos que nuestro estudio contribuirá a la literatura debido a que es el primer reporte en el que las medidas obtenidas de las imágenes radiográficas del talo y el calcáneo se asocian con deformidades del pie.

Treatment of Brachymetatarsia by Distraction Osteogenesis Using Monolateral External Fixator / Tratamento da braquimetatarsia por distração osteogênica com fixador externo monolateral

Abstract 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.

Congenital Clubfoot - Is the Ponseti Method the Definitive Solution? / Pé torto congênito - O método Ponseti é a solução definitiva?

Abstract 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 O pé torto congênito é uma das deformidades mais comuns ao nascimento. A inadequação ou ausência do tratamento provoca sérias limitações aos portadores desta condição. O tratamento inicial pelo método Ponseti garante resultados funcionais superiores a outras modalidades de tratamento propostas anteriormente, porém as recidivas e os pés negligenciados ainda são um desafio na atualidade. O entendimento da fisiopatologia da doença, da anatomia e biomecânica local e uma minuciosa avaliação clínica e radiológica dos pacientes são imprescindíveis para entendermos o limite do método e escolhermos o melhor tratamento.

Deformidades de los pies en niños / Foot deformities in children

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

Resultados funcionales del tratamiento de coaliciones calcaneo-escafoideas con reseccion e interposicion de grasa autologa. Experiencia de dos centros / Patient-reported outcomes of calcaneonavicular coalitions treated with surgical excision and fat graft interposition: A two-center experience

Objetivo: Evaluar los resultados clínico-radiográficos y las complicaciones en pacientes <18 años con coaliciones calcáneo-escafoideas (CCE) sintomáticas tratados con resección e interposición de grasa autóloga de la región glútea. Materiales y métodos: Se analizó retrospectivamente a los pacientes con CCE sintomáticas operados con dicha técnica, en dos instituciones, y un seguimiento mínimo de 2 años. Se analizaron los datos demográficos y las complicaciones posoperatorias. Los resultados funcionales fueron evaluados con la escala AOFAS y la EAV. Se determinó la presencia de recidiva en la radiografía oblicua más reciente (defecto remanente <50%). Resultados: Entre enero de 2008 y enero de 2018, se operó a 52 pacientes (65 pies) con CCE. Cuarenta (48 pies) cumplían con los criterios de inclusión. La edad promedio al operarse era de 11.9 años. El seguimiento promedio fue de 43 meses. El puntaje AOFAS promedio mejoró significativamente de 58,9 ± 8,2 precirugía a 92,9 ± 7,8 después (p <0,001). El puntaje promedio preoperatorio de la EAV era de 6,9 ± 2,5 y de 0,49 ± 1,1 (p <0,001) en el último seguimiento. El 87,5% no tenía síntomas en el último control y 5 pacientes (6 pies) sufrían molestias ocasionales con la actividad física intensa. Hubo 5 complicaciones posoperatorias: dehiscencia de la herida e infección superficial. Dos pies (4,2%) presentaron recidiva radiográfica de la coalición aunque ningún paciente requirió revisión. Conclusión: La resección de CCE y la interposición de grasa autóloga permiten aliviar el dolor y mejorar la función con una baja tasa de complicaciones en la población pediátrico-adolescente. Nivel de Evidencia: IV

background: The purpose of the present study was to evaluate clinical/radiographic outcomes, and complications for calcaneonavicular coalition (CNC) excision and fat graft interposition in patients under the age of 18. materials and methods: A retrospective review of all pediatric patients surgically treated with symptomatic CNC at two institutions was performed. Demographic data and postoperative complications were recorded. Functional results were evaluated with AOFAS Ankle-hindfoot Scale and Visual analog scale (VAS). Radiographic assessment of coalition recurrence was performed on the most recent oblique radiograph (resect-ed gap remaining <50%). Results: Between January 2008 and January 2018, 52 patients (65 feet) with CNC were surgically treated. Forty patients (48 feet) met the inclusion criteria and were available for evaluation. The average age at surgery was 11.9 years old (range 9-17 years old). The average follow-up was 43 months. The average AOFAS score improved from 58.9±8 points preoperative to 92.9±7.8 points postoperatively (p<0.001). Preoperative pain scores averaged 6.9 ± 2.5 points. At the last follow-up, the VAS score was 0.49 ±1.1 points (p<0.001). Most patients (87.5%) were painless at the last follow-up and five patients (6 feet) had occasional pain with strenuous activities. Five complications were recorded: wound dehiscence (N=3) and superficial infection (N=2). Two feet (4.2%) had coalition regrowth on the postoperative radiographs without requiring further surgery. Conclusion: Calcaneonavicular coalition excision with fat graft interposition can improve function and relieve pain with a low rate of complications in the pediatric adolescent population. Level of Evidence: IV

Reconstrucción con colgajo peroneo posterior para cobertura de defectos del tercio distal de la pierna y el tercio proximal del pie / Reconstruction with posterior peroneal flap to cover defects in the distal third of the leg and the proximal third of the foot

El colgajo peroneo posterior es un colgajo fasciocutáneo, que está basado en 4 posibles fuentes como son perforantes fasciocutáneas de la arteria peronea, perforantes fasciocutáneas de la arteria tibial posterior, perforantes venocutáneas de la vena safena menor y perforantes neurocutáneas del nervio sural. El objetivo de este trabajo es describir la técnica quirúrgica y demostrar la versatilidad que tiene el colgajo peroneo posterior para la reconstrucción y cobertura de defectos del tercio distal de la pierna y el tercio proximal del pie, proporcionando el potencial para el cierre simple y eficiente de dichos defectos. Este colgajo proporciona grandes ventajas debido a que es reproducible en cualquier centro quirúrgico y no requiere un entrenamiento específico en microcirugía del cirujano y del resto del equipo quirúrgico. Si bien las complicaciones existen, la mayoría no son graves y en general son de resolución simple. En los últimos años, se ha incrementado el empleo del colgajo fasciocutáneo peroneo posterior para lograr la cobertura de los defectos de partes blandas del tercio distal de la pierna y pie. El éxito de estos colgajos está relacionado con el tipo de paciente y de su lesión: el porcentaje es alto en pacientes jóvenes y sanos en quienes el origen del defecto es traumático.

The posterior peroneal flap is a fasciocutaneous flap, which is based on 4 possible sources such as fasciocutaneous perforations of the peroneal artery, fasciocutaneous perforations of the posterior tibial artery, venocutaneous perforations of the saphenous vein, and neurocutaneous perforators of the sural nerve. The objective of this work is to describe the surgical technique and demonstrate the versatility of the posterior peroneal flap for the reconstruction and coverage of defects in the distal third of the leg and the proximal third of the foot, providing the potential for simple and efficient closure of said defects. It provides great advantages because it is reproducible in any surgical center and does not require specific training in microsurgery of the surgeon and the rest of the surgical team. Although complications do exist, most are not serious and are generally of simple resolution. In recent years, the use of the posterior peroneal flap has been increased to achieve coverage of soft tissue defects of the distal third of the leg and foot. The success of these flaps is related to the type of patient and his injury, the success rate is high in young and healthy patients in whom the origin of the defect is traumatic.

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.

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.

Alargamiento óseo con minitutor externo como tratamiento de braquimetatarsianos / Bone lengthening with external mini-fixator as treatment for brachymetatarsals

Introducción: La braquimetatarsia es un acortamiento de algún metatarsiano, debido principalmente a una detención prematura del crecimiento de la fisis. Es más frecuente en mujeres, y afecta, sobre todo, al cuarto y al primer metatarsiano. El objetivo de este estudio fue evaluar los resultados del tratamiento mediante alargamiento óseo progresivo con minitutor externo. Materiales y Métodos: Estudio descriptivo retrospectivo. Serie de casos. Se analizaron los resultados de los pacientes operados con esta técnica en nuestro Centro. Se analizaron 6 casos, dos con braquimetatarsia bilateral. Todas eran mujeres y tenían braquimetatarsia del 4.° metatarsiano. El promedio de edad era de 14 años. Se evaluaron los siguientes aspectos: alargamiento en milímetros y complicaciones, como retraso de la consolidación, infección, luxación metatarsofalángica, articulación metatarsofalángica en flexión y satisfacción del paciente. Resultados: Se logró un alargamiento promedio de 15 mm. Dos pacientes tuvieron una infección superficial de las agujas. Una paciente evolucionó con luxación de la articulación metatarsofalángica; otra, con flexión de la articulación metatarsofalángica. No hubo complicaciones neurovasculares. Conclusiones: El alargamiento óseo guiado con tutor externo es un tratamiento seguro y eficaz, además lograría un largo mayor en milímetros que el alargamiento en un tiempo, con un mejor control del alargamiento de partes blandas y estructuras neurovasculares. Todas las complicaciones se resolvieron de manera simple, no afectaron el resultado final del tratamiento. Las complicaciones concuerdan con las descritas en la literatura internacional. Nivel de Evidencia: IV

Introduction: Brachymetatarsia is a shortening of any metatarsal bone, mainly due to premature growth arrest of the growth plate. It is more frequent in women, the fourth and the first metatarsal being the most affected bones. The aim of this study was to evaluate the outcomes of progressive bone lengthening with external mini-fixator. Methods: This is a retrospective, descriptive, case series study in which we analyzed the outcomes of all patients operated on with this technique in our Center. Six cases were evaluated, two of them presented bilateral brachymetatarsia. All patients were women, and had brachymetatarsia of the 4th metatarsal. The average age was 14 years. The following aspects were evaluated: lengthening in millimeters and presence of complications, such as delayed consolidation, infection, metatarsophalangeal joint dislocation, metatarsophalangeal joint in flexion and patient satisfaction. Results: On average, an increase of 15 mm was achieved. Two cases presented superficial infection at the needle insertion site. One patient progressed to metatarsophalangeal joint dislocation, and another one to metatarsophalangeal joint flexion. No neurovascular complications were observed. Conclusions: Bone lengthening with external fixator is a safe and effective treatment. A greater length in millimeters can be achieved in comparison to one-stage lengthening, as well as an improved soft-tissue neurovascular stretching. All complications resolved smoothly and did not affect final treatment results. Complications are similar to those described in the international literature. Level of Evidence: IV

Concurrent SHORT syndrome and 3q duplication syndrome

SHORT syndrome is an extremely rare congenital condition due to a chromosomal mutation of the PIK3R1 gene found at 5q13.1. SHORT is a mnemonic representing six manifestations of the syndrome: (S) short stature, (H) hyperextensibility of joints and/or inguinal hernia, (O) ocular depression, (R) Rieger anomaly, and (T) teething delay. Other key aspects of this syndrome not found in the mnemonic include lipodystrophy, triangular face with dimpled chin (progeroid facies, commonly referred to as facial gestalt), hearing loss, vision loss, insulin resistance, and intrauterine growth restriction (IUGR). 3q duplication syndrome is rare syndrome that occurs due to a gain of function mutation found at 3q25.31-33 that presents with a wide array of manifestations including internal organ defects, genitourinary malformations, hand and foot deformities, and mental disability. We present a case of a 2 year and 3 month old male with SHORT syndrome and concurrent 3q duplication syndrome. The patient presented at birth with many of the common manifestations of SHORT syndrome such as bossing of frontal bone of skull, triangular shaped face, lipodystrophy, micrognathia, sunken eyes, and thin, wrinkled skin (progeroid appearance). Additionally, he presented with findings associated with 3q duplication syndrome such as cleft palate and cryptorchidism. Although there is no specific treatment for these conditions, pediatricians should focus on referring patients to various specialists in order to treat each individual manifestation.

Guayaquil - Ecuador

INTRODUCCIÓN: La braquimetatarsia es una enfermedad poco conocida e infrecuente, consiste en el acortamiento de uno o más metatarsianos, generalmente congénita. Existen diversos tipos de tratamiento. El objetivo de este estudio es describir los resultados en el tratamiento mediante elongación ósea progresiva utilizando mini fijador externo. MÉTODOS: Se trata de un estudio descriptivo observacional, incluyeron siete pacientes en el periodo, entre enero 2009 a diciembre 2015, edad comprendida entre 13 y 53 años. Se realizó elongación por callotaxis con minifijador externo y seguimiento a los pacientes con controles clínicos y radiológicos durante un año. RESULTADOS: Los pacientes fueron de sexo femenino, presentaron afección de cuarto metatarsiano. Tiempo de alargamiento promedio de seis semanas, longitud promedio de alargamiento de 17 mm (15 a 20 mm). El fijador externo fue retirado después de observar la consolidación ósea del segmento elongado con una radiografía del pie en tres proyecciones. Se observó que los pacientes consultaron por deformidad estética, dolor al utilizar calzado debido a la deformidad de dedos adyacentes que acompañaba a su braquimetatarsia con metatarsalgia debida hiperqueratosis plantar y alteración en la parábola metatarsal. CONCLUSIONES: El alargamiento óseo mediante distracción progresiva, es una buena opción para el tratamiento con resultados satisfactorios. Se recomienda realizar tratamiento quirúrgico para corregir la deformidad y debe ser realizado después que cierren los cartílagos de crecimiento en el pie.

BACKGROUND: The brachymetatarsia is a little known and infrequent disease. It consists of shortening of one or more metatarsals, usually of congenital origin. There are several types of treatments; The goal of this study is to describe the results in the treatment with progressive bone elongation using external mini-fixator. METHODS: This is an observational descriptive study, which includes seven patients during the period of January 2009 and December 2015, aged between 13 and 53 years. All of them underwent lengthening through callotaxis with external mini-fixator, after the treatment, followed up for one year with clinical and radiographic controls. RESULTS: The patients were female and presented shortening of the fourth metatarsal. Lengthning average time six weeks, length average of 17 mm (from 15 to 20 mm). The external fixator was retreated after observing the bone healed of the section lenghtening with a radiograph of foot in three projections. Patients consulted for aesthetic deformity, pain for using footwear due to the anormality of the adjacent toes and pain for the hyperqueratosis and alteration in the metatarsal parabole. CONCLUSIONS: The bone lengthening through the progressive distraction is a good option to treat with satisfactory results. It is advisable surgical treatment to correct the deformity and the operation is realized after the growth cartilages

Evaluation of the Outcomes according to Etiology in the Pediatric Pes Planovalgus after Lateral Column Lengthening: By Radiologic and Pedobarographic Measurements / 대한정형외과학회잡지

PURPOSE: Pes planovalgus is one of the most common foot deformities among pediatric orthopedic diseases and is divided into idiopathic and neuromuscular planovalgus according to its etiology. This study evaluated the radiologic and pedobarographic outcomes of the treatment for pes planovalgus in children treated with lateral column lengthening, compared the outcomes according to the etiology, and investigated the correlation between the radiologic and pedobarographic findings. MATERIALS AND METHODS: Sixty-three patients (97 feet), who underwent lateral column lengthening, were divided into groups of 30 patients (47 feet) with neuromuscular disease and 33 patients (50 feet) with idiopathic etiology. The preoperative, immediately postoperative, 1 year, and 3 year follow-up radiographic measurements on the plain radiograph antero-posterior (AP) and lateral view were compared. In pedobarography, the foot pressures were subdivided into 4 areas to measure the contact time, contact area, peak pressure, and maximum force. The pre- and postoperative pedobarographic measurements were compared and the correlations between the radiographic and pedobarographic measurements were evaluated. RESULTS: The radiographic index at the 1st postoperative year and 3rd postoperative follow-up did not show significant differences according to the etiology. In pedobarography, idiopathic planovalgus showed a significant increase in the maximum force in the hindfoot and forefoot. The correlation between the radiologic findings and pedobarographic findings was statistically significant between the tibiocalcaneal angle in the lateral view and the maximum force, and the contact area of hindfoot on pedobarography, between tibiocalcaneal angle in the lateral view and the contact area of the toes in idiopathic planovalgus. In neuromuscular planovalgus, the peak pressure in the hindfoot had a strong negative correlation with talonavicular coverage angle in the AP view and talo-1st metatarsal angle, and the talohorizontal angle in the lateral view. CONCLUSION: Lateral column lengthening is an effective surgical procedure for flatfoot patients. On the other hand, the radiographic examination has limitations for accurate assessments of the postoperative results and prognosis. Qualitative and quantitative evaluations are available by pedobarography and it is a useful instrument for an evaluation of planovalgus when used in conjunction with radiography.

Tratamiento integral del antepié con doble braquimetatarsia bilateral en un tiempo quirúrgico. Reporte de un caso / Case report: comprehensive treatment of forefoot with double brachymetatarsia in one surgical stage

Resumen: La braquimetatarsia (acortamiento metatarsal) afecta directamente el arco transverso del pie condicionando graves deformidades como hallux valgus, divergencia digital, dedo supraaducto, metatarsalgia, todas estas alteran la biomecánica del pie y la marcha. El tratamiento se realiza mediante dos técnicas principales, elongación en un solo tiempo quirúrgico con interposición de injerto óseo o elongación por callotaxis con minifijador externo. Existen variantes de ambas técnicas con la finalidad de disminuir las desventajas de cada una de ellas. El objetivo del tratamiento debe ser devolver la armonía estructural del antepié, con lo que mejora la biomecánica, traduciéndose en una evolución satisfactoria para los pacientes. En este artículo se presenta una técnica quirúrgica para pies con fisis cerradas que busca la reestructuración de la fórmula metatarsal y el restablecimiento de la estética y función. En el caso reportado se efectuó alargamiento en un solo tiempo del metatarsiano afectado con interposición de injerto óseo, acortamiento a los metatarsianos adyacentes, corrección del hallux valgus realizando las osteotomías necesarias y el tratamiento de las deformidades de los dedos menores con los métodos requeridos para cada caso. Esta técnica quirúrgica tiene como ventaja la corrección de todo el antepié en un solo tiempo quirúrgico sin necesidad de fijador externo ni de sus cuidados postoperatorios. Sus principales desventajas son la dependencia del injerto óseo estructural y la necesidad de vendaje funcional postquirúrgico hasta la consolidación ósea. En la paciente tratada se obtuvieron resultados clínicos y radiográficos satisfactorios.

Abstract: Brachymetatarsia (shortening of the metatarsal) directly affects the transversal arch of the foot causing severe deformities, such as hallux valgus, divergent toes, overlapping toes, metatarsalgia, all of these alter the biomechanics of the foot and gait. Treatment consists of two main techniques, one-stage lengthening with bone graft or elongation through callotaxis with external fixator; there are variants of both techniques used to minimize the disadvantages of each. The objective of treatment must be to return the structural harmony to the forefoot, improving the biomechanics, resulting in a satisfactory outcome for the patients. This article presents a surgical treatment for feet with closed physis to obtain the appropriate metatarsal formula and to reestablish aesthetics and function. This case was treated by means of one-stage lengthening with bone graft to the affected metatarsal; shortening of the adjacent metatarsals; hallux valgus alignment through the necessary osteotomies and the treatment of deformities of the lesser toes as needed. This surgical technique has as one of its advantages the correction of the entire forefoot at one time, without the need of an external fixator and its required postoperative care. Its main disadvantages are its dependence on structural bone graft and the need of postoperative dressing until healing of the bone has taken place. Satisfactory clinical and radiographical outcomes were obtained in treated patient.
