ABSTRACT

SUMMARY: The os intermetatarseum is an accessory bone located in the foot, usually between the first 2 metatarsals and the cuneiform bone. It can be presented as free, articulated or in a fused fashion. It is a very unusual variation found in less than 13 % of the population. A 27-year-old patient presented to the emergency service due to an ankle lesion. Physical exam showed pain and limited range of motion while supporting partial load. Radiographic imaging showed a bony trace near the base of the first and second metatarsals, diagnosed as the os intermetatarseum. Formation of this supernumerary bone begins as a separate ossification center. Most cases are asymptomatic; however, compression of the deep peroneal nerve branches by the os intermetatarseum can lead to pain. Some authors suggest that the presence of this bone may cause hallux valgus. The intermetatarseum can lead to diagnostic confusion, mainly related to Lisfranc fracture. Its origin is still little understood.


El os intermetatarseum es un hueso accesorio ubicado en el pie, generalmente entre los 2 primeros metatarsianos y el hueso cuneiforme. Puede presentarse de forma libre, articulada o fusionada. Es una variación muy inusual que se encuentra en menos del 13 % de la población. Paciente de 27 años que acude a urgencias por lesión en tobillo. El examen físico mostró dolor y rango de movimiento limitado mientras soportaba una carga parcial. Las imágenes radiológicas mostraron un rastro óseo cerca de la base del primer y segundo metatarsianos, diagnosticado como os intermetatarseum. La formación de este hueso supernumerario comienza como un centro de osificación separado. La mayoría de los casos son asintomáticos; sin embargo, la compresión de las ramas profundas del nervio fibular en el espacio intermetatarsiano puede provocar dolor. Algunos autores sugieren que la presencia de este hueso puede provocar hallux valgus. El hueso intermetatarsiano puede llevar a confusión diagnóstica, principalmente relacionada con la fractura de Lisfranc. Su origen aún es poco comprendido.

ABSTRACT

ABSTRACT Objective: To describe the technique, analyze possible radiographic correction and evaluate the clinical result of medial and plantar calcaneal displacement osteotomy associated with opening wedge cuboid osteotomy for flexible flatfoot correction. Methods: 23 patients (30 feet) diagnosed with flexible flat foot treated with plantar and medial calcaneal displacement osteotomy associated with opening wedge cuboid osteotomy were evaluated retrospectively. In the lateral radiographs calcaneal pitch and Meary's angle were the radiographic parameters evaluated; while the talonavicular coverage angle was evaluated in the anteroposterior radiographs. To assess the clinical outcome of the surgical procedure, the American Orthopedic Foot and Ankle Society Score (AOFAS) for the ankle and hindfoot was adopted. Results: The mean values of the evaluated angles and AOFAS score for ankle and hindfoot significantly improved when comparing pre- and postoperative values. Conclusion: Plantar and medial calcaneal displacement osteotomy associated with an opening wedge cuboid osteotomy is able to improve radiological and clinical parameters of child patients with flexible flatfoot. Level of Evidence III, Retrospective Comparative Study.


RESUMO Objetivo: Descrever a técnica, analisar possíveis correções radiográficas e avaliar o resultado clínico da osteotomia de deslocamento medial e plantar do calcâneo associada à osteotomia em cunha de adição do cuboide para correção do pé plano flexível de crianças. Métodos: Foram avaliados retrospectivamente 23 pacientes (30 pés) com diagnóstico de pé plano flexível tratadas com osteotomia de deslocamento plantar e medial do calcâneo associada à osteotomia em cunha de adição do cuboide. Os parâmetros radiográficos avaliados nas imagens em perfil foram o pitch do calcâneo e o ângulo de Meary, enquanto nas radiografias anteroposteriores o ângulo de cobertura do tálus. Para avaliar o resultado clínico do procedimento cirúrgico, foi adotado o escore da American Orthopaedic Foot and Ankle Society (AOFAS) para tornozelo e retropé. Resultados: Os valores médios dos ângulos avaliados e do escore AOFAS para tornozelo e retropé melhoraram significativamente na comparação dos resultados pré e pós-operatórios. Conclusão: A osteotomia de deslocamento plantar e medial do calcâneo associada à osteotomia em cunha de adição do cuboide é capaz de melhorar os parâmetros radiológicos e clínicos de crianças com pé plano flexível.

ABSTRACT

El conjunto de patologías bajo el nombre de síndromes dolorosos de pie y tobillo engloban diferentes tendinopatías asociadas entre varios factores clínicos a la presencia de huesos accesorios tarsianos. La correcta identificación y diferenciación radiológica de estas variantes anatómicas en virtud de su capacidad de influir en la dinámica normal del tarso motivan el estudio de su incidencia. Nuestro objetivo es determinar la presencia de distintos huesos accesorios tarsianos en una muestra poblacional. Se expone el resultado de un estudio observacional retrospectivo en 240 pacientes entre 15 y 85 años de edad atendidos en un centro privado de la ciudad de Las Piedras, Canelones, con radiografías de pie y tobillo preexistentes en la base de datos institucional. Se determinó presencia de huesos accesorios tarsianos en 23 pacientes (9,58%), identificando hallazgos de Os Trigonum (1,66%), Proceso de Stieda (3.33%), Os Peroneum (2,93%) y Os Navicular (1,66%). Se presenta en tablas el análisis de frecuencia correspondiente y estudio de contingencia entre variantes encontradas, edad y sexo del paciente. El resultado de la investigación busca aportar al conocimiento de variantes anatómicas normales correlativas a procesos patológicos infradiagnosticados, desde el rol de la anatomía radiológica.


The group of pathologies under the name of foot and ankle pain syndromes encompass different tendinopathies associated among various clinical factors with the presence of accessory tarsal bones. The correct identification and radiological differentiation of these anatomical variants, by virtue of their ability to influence the normal dynamics of the tarsus, motivated the study of their incidence. Our objective is to determine the presence of different tarsal accessory bones in a population sample. Here we present the results of a retrospective observational study in 240 patients between 15 and 85 years of age, treated in a private health center in the city of Las Piedras, Canelones, with pre-existing ankle and foot x-rays in the institutional database. The presence of tarsal accessory bones was determined in 23 patients (9.58%), identifying findings of Os Trigonum (1.66%), Stieda Process (3.33%), Os Peroneum (2.93%) and Os Navicular (1, 66%). The corresponding frequency analysis and contingency study between the variants found, age and sex of the patient are exposed in tables. The result of the research seeks to contribute to the knowledge of normal anatomical variants correlative to under diagnosed pathological processes, from the role of radiological anatomy.

ABSTRACT

ABSTRACT 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.


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.

ABSTRACT

ABSTRACT Objective To use magnetic resonance imaging to assess the prevalence of foot and ankle ligament injuries and fractures associated with ankle sprain and not diagnosed by x-ray. Methods We included 180 consecutive patients with a history of ankle sprain, assessed at a primary care service in a 12-month period. Magnetic resonance imaging findings were recorded and described. Results Approximately 92% of patients had some type of injury shown on the magnetic resonance imaging. We found 379 ligament injuries, 9 osteochondral injuries, 19 tendinous injuries and 51 fractures. Only 14 magnetic resonance imaging tests (7.8%) did not show any sort of injury. We observed a positive relation between injuries of the lateral complex, syndesmosis and medial ligaments. However, there was a negative correlation between ankle ligament injuries and midfoot injuries. Conclusion There was a high rate of injuries secondary to ankle sprains. We found correlation between lateral ligament injuries and syndesmosis and deltoid injuries. We did not observe a relation between deltoid and syndesmosis injuries or between lateral ligamentous and subtalar injuries. Similarly, no relation was found between ankle and midfoot injuries.


RESUMO Objetivo Avaliar na ressonância magnética a prevalência das diferentes lesões ligamentares do tornozelo e do pé, bem como de fraturas não diagnosticáveis radiograficamente, em pacientes com queixa de entorse do tornozelo. Métodos Foram incluídos no estudo 180 pacientes consecutivos, com história de entorse do tornozelo, atendidos em um serviço de Atenção Primária no período de 12 meses. Os achados dos exames de ressonância magnética foram catalogados e descritos. Resultados Aproximadamente 92% dos pacientes apresentaram algum tipo de lesão na ressonância. Dentre as injúrias observadas, estavam 379 lesões ligamentares, 9 lesões osteocondrais, 19 lesões tendíneas e 51 fraturas. Apenas 14 ressonâncias magnéticas (7,8%) não mostraram qualquer tipo de lesão. Observamos relação positiva entre lesões do complexo lateral, sindesmose e medial. No entanto, houve correlação negativa entre lesões ligamentares do tornozelo e aquelas do mediopé. Conclusão Foi alta a ocorrência de lesões secundárias à entorse. Apontamos correlação entre as lesões ligamentares laterais com as sindesmodais e do deltoide. Não notamos relação entre as lesões do deltoide e da sindesmose, e nem entre as ligamentares laterais e a subtlalar. Também não foram observadas relações entre as lesões do tornozelo e as do mediopé.

ABSTRACT

Abstract Tarsal navicular fractures, as well as other midfoot injuries, are rare, and can result in severe impairment if not properly treated. Parkour, a modern sport, is gaining popularity among young individuals in urban areas, and is prone to result in high-energy trauma, which is scarcely described in the literature. The following is a report of a rare case of tarsal navicular fracture in a 17-year-old male, sustained during parkour practice, which was treated successfully with open reduction and internal fixation. The description of the case emphasizes the challenges of its approach; the discussion highlights the treatment options and goals. The case should also raise awareness about the increasing occurrence of these uncommon lesions.


Resumo As fraturas do escafoide társico, bem como outras lesões do médiopé, são raras e podem resultar em incapacidade grave se não forem tratadas adequadamente. Parkour, um esporte moderno, está ganhando popularidade entre os jovens em áreas urbanas, e é propenso a traumatismos de alta energia, sendo estes escassamente descritos na literatura. O presente relato trata de um caso de fratura rara do escafoide társico em um paciente do sexo masculino de 17 anos, ocorrida durante a prática de parkour, que foi tratada com sucesso, com redução aberta e fixação interna. A descrição do caso enfatiza os desafios na sua abordagem; a discussão destaca as opções de tratamento e seus objetivos. O caso também deve alertar sobre a ocorrência crescente dessas lesões incomuns.

ABSTRACT

Fraturas por estresse são lesões que ocorrem devido a uma força de baixa intensidade, porém repetida sobre o osso por um longo período de tempo. Esta acomete mais militares e alguns atletas, porém sua incidência vem aumentando na população. Com exceção do calcâneo, estas lesões raramente acometem os ossos do tarso. Cuboide e cuneiforme lateral são dois ossos dessa região do mediopé com poucos relatos na literatura relativos à fratura por estresse. Estes apresentam uma sintomatologia em comum, com dor local, sensibilidade à palpação, possível edema e alterações de pele. Atualmente o melhor método diagnóstico é a ressonância magnética. São fraturas classificadas como de baixo risco e o tratamento é conservador aliado à terapia farmacológica.


Stress fractures are injuries that happen due to a low but repetitive force over the bone during a long period. It is more common in military personnel and in some athletes; however, its incidence has been rising among the population. With exception to the calcaneum, these injuries rarely happen in the tarsal bones. Cuboid and lateral cuneiform are two bones of the midfoot with few literature reports of a stress fracture. These present a common symptomatology with local pain, tenderness to palpation, possible edema and skin changes. Currently, the best diagnostic method is the magnetic resonance imaging. These fractures are classified as low risk and its treatment is conservative, allied to pharmacologic therapy.

ABSTRACT

SUMMARY OBJECTIVE: The objective of this study is to report the results of arthroscopic debridement of the subtalar joint in eight patients with Sinus Tarsi Syndrome (STS) refractory to conservative treatment. METHODS: This is a retrospective study of eight patients with STS who underwent subtalar arthroscopy for debridement of the sinus tarsi between January 2015 and January 2017 after six months of conservative treatment. All patients answered an epidemiological questionnaire and underwent functional evaluation with the Visual Analogue Pain Scale (VAS) and the American Orthopedic Foot and Ankle Society Score (AOFAS) in the preoperative and in the last evaluation (average of 12 months - 6-24 months). RESULTS: All patients showed severe synovitis in the region. Seven patients had remnants of the talocalcaneal ligaments and six of the cervical ligament. AOFAS increased by 30 points on average (51.75 in the preoperative period to 82.62 in the last follow-up) and the VAS decreased on average by 5 points (7.37 preoperatively to 2.12 in the last follow-up). These results were statistically significant with p = 0.043 and p = 0.032 respectively. Six patients described the result as excellent and two as good. No complications were reported. All patients returned to sports after six months of follow-up. CONCLUSION: The arthroscopic debridement of the subtalar joint is an effective and safe alternative in the treatment of STS refractory to conservative treatment. More studies, with a prospective methodology, are necessary to prove the results of this technique.


RESUMO OBJETIVO: O objetivo desse estudo é relatar os resultados do desbridamento artroscópico da subtalar em oito pacientes portadores da Síndrome do Seio do Tarso (SST) refratária ao tratamento conservador. MÉTODOS: Este é um estudo retrospectivo com oito pacientes com diagnóstico de STT que foram submetidos à artroscopia subtalar para desbridamento do seio do tarso entre janeiro de 2015 e janeiro de 2017, após seis meses de tratamento conservador. Todos os pacientes responderam questionário epidemiológico e foram submetidos à avaliação funcional com a Escala Visual Analógica de dor (EVA) e o American Orthopaedic Foot and Ankle Society Score (Aofas) no pré-operatório e na última avaliação, em uma média de 12 meses (6-24 meses). RESULTADOS: Todos os pacientes exibiram intensa sinovite na região. Sete pacientes tinham resquícios de ligamentos talocalcaneanos e seis do ligamento cervical. O Aofas aumentou 30 pontos em média (51,75 no pré-operatório para 82,62 no último seguimento) e a EVA diminuiu em média 5 pontos (7,37 no pré-operatório para 2,12 no último seguimento). Esses resultados foram estatisticamente significativos com p = 0,043 e p = 0,032, respectivamente. Seis pacientes descreveram o resultado como excelente e dois como bom. Nenhuma complicação foi relatada. Todos os pacientes retornaram ao esporte após seis meses de acompanhamento. CONCLUSÃO: O desbridamento artroscópico da subtalar é uma alternativa eficaz e segura no tratamento da SST refratária ao tratamento conservador. Mais estudos, com metodologia prospectiva, são necessários para comprovar os resultados da técnica.

ABSTRACT

Tarsal tunnel syndrome is a rare, under diagnosed and often confused neuropathy with other clinical entities. There is a lack of population studies on this disease. Herein, we performed a non-systematic review of articles between January 1992 and February 2018. Although with a less complex anatomy comparing to the carpal tunnel, the tarsal tunnel is source of pain and some other conditions. Treatment involves conservative measures such as analgesics and physical therapy rehabilitation or surgical procedures in case of conservative treatment failure. Randomized control studies are lack and mandatory for uncover the best modality of treatment for this condition.


A Síndrome do túnel do tarso é uma rara e subdiagnosticada neuropatia geralmente confundida com outras entidades clínicas. Há falta de estudos populacionais sobre a doença. Assim sendo, realizamos uma revisão da literatura de artigos entre Janeiro de 1992 e fevereiro de 2018. Apesar de possuir uma anatomia de menor complexidade comparada ao túnel do carpo, o túnel do tarso é origem de dor e algumas outras condições. O tratamento envolve medidas conservadoras como analgésicos e terapia de reabilitação ou procedimentos cirúrgicos, em caso de falha do tratamento conservador. Estudos randomizados são escassos e necessários para descoberta da melhor modalidade de tratamento desta condição.

ABSTRACT

O osso navicular acessório, do qual foram descritas três variantes, é frequentemente considerado uma variação anatômica normal.É uma anomalia congênita em que a tuberosidade do navicular se desenvolve a partir de um centro de ossificação secundário e tem uma incidência estimada entre 2% e 14% com maior incidência em mulheres sendo bilateral em 50-90% dos casos. Nosso objetivo foi relatar um caso e revisar a literatura acerca desta lesão incomum, utilizando-se da revisão do prontuário, registro fotográfico do método diagnóstico e revisão da literatura. Mulher de 59 anos com dor no lado medial do pé esquerdo há dois anos, com piora ao andar. Exame físico com testes específicos do tornozelo negativos, sem hematoma ou edema. Nega torção, trauma e cirurgias. A ressonância magnética demonstra osso navicular acessório tipo II e osso navicular, ambos com edema. Estes achados com quadro clínico são compatíveis com síndrome do osso navicular acessório. Este relato demonstra a dificuldade de diagnosticar essa lesão, pois seu o exame físico é inespecífico, podendo simular patologias mais complexas, necessitando de exames complementares para seu correto diagnóstico (AU)


The accessory navicular bone, of which three variants have been described, is often considered as a normal anatomic and roentgenographic variant. Is a congenital anomaly in which the tuberosity of the navicular bone develops from a secondary ossification center and it has an incidence estimated between 2% and 14% with higher incidence in women being bilateral in 50-90% of the cases. Our aim was to report a case and review the literature about this uncommon lesion. We carried out a review of medical records, photographic record of diagnostic method, and review from the literature. A 59 years old woman with pain in the medial side of the left foot for two years. Refers worsening with walking. Physical examination with specific ankle negative tests, without bruise or edema. Denies torsion, trauma and surgeries. Magnetic resonance imaging demonstrates type II accessory navicular bone with edema and navicular bone edema. These findings with clinical complaint are compatible with accessory navicular bone syndrome. This report demonstrates the difficulty of diagnosing this lesion, since its physical examination is non-specific, and it can simulate more complex pathologies, requiring complementary tests for its correct diagnosis (AU)

ABSTRACT

Objective@#To explore the application effect of tarso-conjunctival flap for one-stage repairing eyelid posterior defect after resection of eyelid tumors.@*Methods@#From June 2014 to December 2016, 33 patients with 33 cases of eyelid posterior tumors were treated, including 21 cases of Pigmented nevus of eyelid, 7 cases of eyelid basal cell carcinoma, 3 cases of eyelid adenocarcinoma and 2 cases of eyelid squamous cell carcinoma. Direct resection was performed for eyelid nevus, Mohs method (intraoperative delivery of frozen sections to control the cut edge) resection was performed for malignant tumors. According to the scope and location of the defect, the tarso-conjunctival flap was used to repair the posterior defect of the eyelid, and the eyelid anterior defect was treated with local flap transfer.@*Results@#All 33 patients were followed up for 3 to 24 months. In addition to the absence of eyelashes in the defect area, one case had mild blepharoptomy (1 mm) and recovered after self-recovery. The remaining cases had recovered in appearance and function of eyelid with no serious complications.@*Conclusions@#The flexible application of tarso-conjunctival flap can basically solve the problem of repairing eyelid posterior defect after resection of eyelid tumors. The operation method has clinical practical value.

ABSTRACT

Resumen: Objetivo: La técnica a través del abordaje del seno del tarso (AST), se ha convertido en una opción cada vez más popular para el tratamiento de las fracturas de calcáneo. A pesar de los buenos resultados reportados, las complicaciones relacionadas con la fijación interna no han sido analizadas aún. A través de mediciones en tomografías computadas con reconstrucción 3D (TC) hemos planteado el objetivo de realizar una descripción del calcáneo aplicada al uso de osteosíntesis en fracturas de dicho hueso. Métodos: Se obtuvieron, retrospectivamente, 24 estudios de TC de 22 pacientes consecutivos que presentaban calcáneos sanos sin antecedente de cirugía ni fractura, 18 hombres y cuatro mujeres, 14 derechos y 10 izquierdos. La edad promedio fue de 45.8 (rango: 19-79) años. Se realizaron mediciones del ancho y largo de tornillos que se necesitarían para fijar una fractura de calcáneo con un montaje predefinido. Resultados: Los resultados están enfocados en mediciones obtenidas de imágenes de TC, las cuales ayudarían al cirujano a un correcto posicionamiento, angulación y largo de los tornillos necesarios para la fijación interna de fracturas de calcáneo. Conclusión: Este estudio describe una serie de mediciones del calcáneo que resultan de utilidad para la fijación interna de fracturas de calcáneo a través del AST. Su propósito es minimizar las complicaciones derivadas del uso de osteosíntesis en estas fracturas.


Abstract: Objective: The mini-invasive technique, through a sinus tarsi approach (STA), has become an increasingly popular choice for the treatment of calcaneal fractures. However, despite the good results reported, the complications related with internal fixation have not yet been analyzed. Using 3D reconstruction CT scans, we proposed doing biometric description of the calcaneus with the purpose of performing osteosynthesis as treatment for calcaneal fractures. Methods: A total of 24 CT scans were retrospectively obtained from 22 consecutive patients with healthy calcanei and no history of surgery or fracture. They included 18 males and 4 females; 14 right and 10 left calcanei. Mean age was 45.8 (range 19-79). The width and length of the screws needed to fix a calcaneal fracture with a predefined montage were measured. Results: The results focus on biometric measurements obtained from CT scans that may help surgeons achieve proper positioning, angulation and length of the screws needed for the internal fixation of calcaneal fractures. Conclusion: This study describes a series of biometric calcaneal measurements that are useful for the internal fixation of calcaneal fractures using a sinus tarsi approach. The purpose is to minimize the complications resulting from osteosynthesis to treat these fractures.

ABSTRACT

El síndrome del túnel del tarso se define como una neuropatía compresiva extrínseca y/o intrínseca del nervio tibial posterior o de una de sus ramas siendo una de sus causas la insuficiencia vascular. Caso clínico: femenina de 51 años, originaria de León, Guanajuato. Hipertensa, síndrome de Guillain-Barré hace ocho años, insuficiencia vascular y obesidad. Inicia con dolor en tobillo y talón izquierdo, manejada con AINES y rehabilitación con mejoría parcial, se realizan radiografías y resonancia magnética nuclear del tobillo izquierdo con datos de pinzamiento posterior, se realiza artroscopía y mejora un mes presentándose dolor intenso en el tobillo y la planta del pie y disestesias, se hace electromiografía con datos de lesión del tibial posterior. Cuenta con historia clínica, perfil prequirúrgico, dorsoplantar y lateral, se realiza una artroscopía encontrándose una tendinitis del Flexor Hallucis Longus (FHL), sinovitis y un pinzamiento posterior del tobillo, se hace sinovectomía, descompresión y un peinado del FHL. Mala evolución, se realiza electromiografía con axonotmesis de la rama plantar medial. Se realiza la liberación del nervio encontrándose el plexo venoso de Lazhortes tortuoso comprimiendo en todo su trayecto. Una de las causas es por la compresión intrínseca secundaria a tumores, modificaciones de la anatomía del túnel del tarso; sin embargo, menos frecuente, las várices pueden confundir el diagnóstico y llegar a producir un daño irreparable para el paciente si no se trata a tiempo. La paciente se encuentra actualmente sin dolor que le posibilita la marcha, con disestesias leves del primer dedo y movilidad limitada para su flexión.


Tarsal tunnel syndrome is defined as an extrinsic and/or intrinsic compressive neuropathy of the posterior tibial nerve or one of its branches. Its causes include venous insufficiency. Clinical case: 51 year-old female patient from León, Guanajuato. Hypertensive, with Guillain-Barré syndrome for eight years, vascular insufficiency and obesity. Her condition started with left ankle and heel pain; she was treated with NSAIDs and rehabilitation and achieved partial improvement. X-rays and MRI of the left ankle showed posterior impingement. She underwent arthroscopy and improved but one month later she presented with severe pain in the left ankle and sole and dysesthesias. Electromyography showed a lesion of the posterior tibial nerve. We had the patient's case history, preoperative tests, and dorsoplantar and lateral X-ray views. The arthroscopic diagnosis was flexor hallucis longus (FHL) tendinitis, synovitis and posterior ankle impingement. Synovectomy, decompression and smoothening of the FHL tendon were performed. The patient did poorly and underwent electromyography with axonotmesis of the medial plantar branch. After the nerve was released, Lazorthes venous plexus was found to be tortuous and compressing the entire nerve tract. The possible causes for this include intrinsic compression secondary to tumors, and anatomical changes of the tarsal tunnel. However, less often varices may confound the diagnosis and cause irreversible damage if not treated timely. The patient is currently pain free and can walk, has mild dysesthesias of the first toe and limited flexion.

ABSTRACT

Os autores avaliaram todos os exames de condução nervosa do nervo tibial dos pacientes com suspeita de neuropatia da hanseníase, aguda ou subaguda, atendidos no Ambulatório de Hansenologia do Instituto Lauro de Souza Lima (ILSL) no período de dois anos. Foram incluídos 75 pacientes, 52 masculinos e 23 femininos, com média de idade de 44,5 anos (21 a 73 anos), totalizando 150 nervos. Procurou-se caracterizar o comprometimento neurofisiológico individualizando-se os ramos plantar medial (PM) e plantar lateral (PL), observou-se que o mais envolvido foio PL com 57,4%, seguido do PM com 42,6%. O tipo de lesão nervosa mais frequente foi a de predomínio axonal, com 66%, seguida pela mielínica, com 28,7%.O envolvimento mais freqüente e desproporcional dor amo PL, além de evidenciar o caráter compressivo do comprometimento do tibial no túnel do tarso, remete a uma mononeuropatia múltipla compressiva nos membros inferiores. A alta prevalência do comprometimento do nervo tibial foi considerada uma marcada doença, da mesma forma que a neuropatia ulnar.


The authors assessed all tibial nerve conduction studies (NCS) of the patients under suspicious of acute or subacute leprosy neuropathy, who have been attended the Leprosy Ambulatory Clinic of the ILSL during a period of two years. Seventy-five patients have been included as follows: 52 male and 23 female, between 21 and 73 years old, with the mean age of 44.5 totaling 150 nerves The medial plantar (MP) and lateral plantar ( (LP) branches were studied separately. The most involved was the LP with 57.4%, followed bythe MP with 42.6%. The most frequent injury among the abnormal nerves was the axonal lesion with 66%, followed by the myelin lesion with 28.7%. The most frequent and disproportional involvement of thePL branch not only demonstrates the compressivecharacter of the tibial nerve injury in the tarsaltunnel but also indicates a multiple entrapment mononeuropathy in the lower limbs. The high prevalence of the tibial nerve injury was considered a hallmark of the disease, as well as the ulnar neuropathy.

ABSTRACT

La primera descripción del túnel del tarso se le atribuye a Richter, en 1897; en 1932 Pollock y Davis describen por primera vez el síndrome, en 1960 Kopell y Thompson describen la clínica del síndrome de túnel del tarso y en 1962 Charles Keck describió el síndrome del túnel del tarso en forma detallada con casos clínicos. Se presenta el caso de un paciente femenino de 61 años que inició su padecimiento en 2010, al presentar talalgia intermitente que se incrementa de forma gradual, seis meses después el dolor es constante y limita la marcha, EVA de 6/10, se diagnostica fascitis plantar, y se envía a fisioterapia sin mejoría a los dos meses de tratamiento. El ultrasonido de fascia plantar, reporta engrosamiento de la misma, con microdesgarros en su inserción en calcáneo, se realiza infiltración de plasma rico en plaquetas en fascia plantar sin mejoría, dos meses después es enviada a sesiones de ondas de choque sin cambios, se revalora caso y se realiza el diagnóstico de síndrome del túnel del tarso en forma clínica y por electromiografía y en 2011 se infiltran esteroide con anestésico local con mejoría temporal. En 2012, encontramos EVA de 7/10 y AOFAS de 54 puntos, se interviene quirúrgicamente y como hallazgo transoperatorio se encuentra trayecto varicoso que disminuía el calibre del túnel del tarso oprimiendo a las estructuras adyacentes. Se presenta el caso clínico y la revisión en la literatura del síndrome del túnel del tarso.


The first description of tarsal tunnel is attributed to Richter in 1897, in 1932 Pollock and Davis described the syndrome for the first time, in 1960 Kopell and Thompson described the clinical features of tarsal tunnel syndrome; and in 1962 Charles Keck described tarsal tunnel syndrome in a detailed manner with clinical cases. We present the case of a 61 year old female patient who presented symptoms in 2010, she had intermittent talalgia that increased gradually, six months later pain is constant and limiting gait, EVA is 6/10, she is diagnosed with plantar fasciitis and is referred to physiotherapy with no improvement after two months of treatment. The plantar fascia ultrasound reports thickening with micro tears in the heel bone attachment, we infiltrated the plantar fascia with platelet rich plasma with no improvement, two months later she has shock wave sessions with no changes observed. We reassess the case and make the diagnosis of tarsal tunnel syndrome clinically and with electromyography and in 2011 we infiltrate a steroid with local anesthesia with temporary improvement. In 2012, we found an EVA of 7/10 and an AOFAS of 54 points, we perform surgery and the intraoperative finding is a varicose vein that decreased the caliber of the tarsal tunnel compressing adjacent structures. The clinical case is presented and we reviewed tarsal tunnel syndrome in the literature.

ABSTRACT

Las fracturas del calcáneo representan aproximadamente 2% de todas las fracturas del cuerpo humano y 60% de las fracturas del tarso. Menos del 7% son bilaterales. Las fracturas intra-articulares desplazadas (Sanders Tipo IV) son el resultado de traumatismos de alta energía, usualmente debido a precipitaciones o accidentes automovilísticos. Es una lesión compleja que se asocia con elevados índices de incapacidad cuando no es tratada de forma correcta y oportuna. Se trata de paciente masculino, de 38 años de edad, quien presenta una fractura bilateral de calcáneo Sanders tipo IV, manejada quirúrgicamente, mediante reducción directa, reconstrucción anatómica del calcáneo, osteosíntesis con placa anatómica y artrodesis subtalar. Las fracturas del calcáneo siguen siendo un gran reto para el cirujano ortopedista y traumatólogo debido a la controversia en cuanto a su manejo. El diagnóstico preciso y precoz, basado en estudios imagenológicos, es necesario para una adecuada caracterización de la fractura, planificación preoperatoria y resolución quirúrgica(AU)


Calcaneal fractures represent approximately 2% of all fractures of the body and 60% of fractures of the tarsus. Less than 7% are bilateral. The displaced intra-articular fractures (Sanders type IV) are the result of high energy trauma, usually because of rainfall or auto accidents. It is a complex injury that is associated with high rates of disability when not treated properly and timely. The case of male 38-year-old man presented with bilateral calcaneal fractures Sanders type IV, which were managed surgically by direct reduction of the calcaneus and anatomical reconstruction píate fixation and anatomic subtalar arthrodesis. Calcaneal fractures remain a major challenge for orthopedic surgeons and trauma due to controversy regarding their management. The early and accurate diagnosis based on imaging studies, it is necessary for proper characterization of the fracture, preoperative planning and surgical resolution(AU)

ABSTRACT

OBJETIVO: Determinar, através de dissecção em cadáveres frescos, a anatomia topográfica do nervo tibial e seus ramos ao nível do tornozelo, em relação ao túnel do tarso. MÉTODOS: Foram realizadas dissecções bilaterais em 26 cadáveres frescos e as localizações da bifurcação do nervo tibial e seus ramos aferidas em milímetros, com relação ao eixo maleolar-calcaneal (EMC). Para os ramos calcâneos, a quantidade e seus respectivos nervos de origens também foram analisados. RESULTADOS: A bifurcação do nervo tibial ocorreu sob o túnel em 88% dos casos e proximalmente em 12%. Quanto aos ramos calcâneos, o medial apresentou-se com um (58%), dois (34%) e três (8%) ramos, com a origem mais comum do nervo tibial (90%) e o inferior com ramo único por perna, tendo o nervo plantar lateral como origem mais comum (70%). Nivel de Evidência V, Opinião de especialista.


OBJECTIVE: Determine, through dissection in fresh cadavers, the topographic anatomy of the tibial nerve and its branches at the ankle, in relation to the tarsal tunnel. METHODS: Bilateral dissections were performed on 26 fresh cadavers and the locations of the tibial nerve bifurcation and its branches were measured in millimeters. For the calcaneal branches, the amount and their respective nerves of origin were also analyzed. RESULTS: The tibial nerve bifurcation occurred under the tunnel in 88% of the cases and proximally in 12%. As for the calcaneal branches, the medial presented with one (58%), two (34%) and three (8%) branches, with the most common source occurring in the tibial nerve (90%) and the lower with a single branch per leg and lateral plantar nerve as origin most common (70%). Level of Evidence, V Expert opinion.

ABSTRACT

En un estudio de pseudocohortes se inspeccionaron los miembros craneales y caudales de 3142 lechones lactantes de 5 a 27 días de vida, para evaluar prevalencia de lesiones y su evolución, clasificándolas por edad y región anatómica. El trabajo se desarrolló en un establecimiento porcino de crianza intensiva, de ciclo completo, todo adentro-todo afuera, con 1200 madres totales y un promedio de 50 partos semanales, con una edad de destete promedio de 24 días. De los 3142 lechones, 249 (7.92%) no presentaron lesiones, en los restantes 2893 (92.8%) se observaron 8415 lesiones, correspondiendo 3869 (46%) a fibrosis, 4314 (51.20%) a heridas y 232 (2.8%) a artritis. De ese total 5165 (61.4%) correspondieron a los carpos, 737 (8.8%) a los tarsos y 2513 (29.9%) a las pezuñas. En lechones de 5-9 días de edad las heridas representaron el 73.8% del total de lesiones, las que tuvieron dos formas de evolución, hacia la fibrosis o la artritis. Esta evolución de las heridas mayormente tiende a la fibrosis en el carpo y a la artritis en el tarso. Se concluye que los miembros de lechones en maternidad presentan alta prevalencia de lesiones bilaterales desde la edad temprana y principalmente en los miembros craneales.


The purpose of this work was to study the prevalence, evolution and type of lesions occurring in the front and back legs of 3142 suckling piglets from 5 to 27 days of age, also classifying ithem according to age and anatomical region. From the total 3142 piglets, 249 (7.92%) did not have any visible lesions. In the other 2893 (92.08%) piglets, a total of 8415 different lesions were observed. Over this total, an amount of 3869 (46%) piglets showed fibrosis, 4314 (51.20%) had different type of injuries and 232(2.8%) presented arthritis. Over the total of 8415 lesions, 5165 (61.4%), 737 (80.8%), and 2513 (29.9%) had lesions on the carpus, tarsus and hoofs, respectively. Injuries represented 73.8% of the total lesions in 5 to 9 days old piglets, which evolved either towards fibrosis or arthritis. Fibrosis was the product of evolution on lesions mainly in the carpus, whereas arthritis evolved mainly in the tarsus.

ABSTRACT

Twenty-five arthrodeses were performed in four cats and 17 dogs using synthetic hydroxyapatite as fresh autogenous graft cancellous bone substitute. Arthrodesis was performed in the carpal joint in eight cases, in the tarsal joint in 10, in the elbow joint in six, and in the knee joint in one case. The mean radiographic follow-up time was 30 days in one animal, 45 days in another animal and 60 days in the 19 remaining cases. Bone union was observed in 24 arthrodeses. Non-union of one elbow arthrodesis was due to failure of stabilization. Restoration of limb functionality was classified as good to excellent in 22 cases. Hydroxyapatite was able to promote bone growth and is suitable for using in routine surgical procedures for small animals


Realizaram-se 25 artrodeses em 21 casos, quatro em gatos e 17 em cães, utilizando hidroxiapatita sintética como substituto ao enxerto ósseo autógeno esponjoso fresco, sendo oito na articulação do carpo, 10 na articulação do tarso, seis na do cotovelo e uma na do joelho. As avaliações radiográficas foram realizadas aos 30 dias em um animal, aos 45 dias em outro e aos 60 dias nos 19 casos restantes. Visibilizou-se união óssea em 24 artrodeses e a não-união em um cotovelo foi atribuída a falha na estabilização. O retorno à função do membro foi classificado de bom a excelente em 22 casos. A hidroxiapatita foi capaz de viabilizar o crescimento ósseo e mostrou-se factível para utilização na prática cirúrgica rotineira em pequenos animais
