Fracturas por avulsión de la tuberosidad posterior del calcáneo "en pico de pato". Evaluación funcional y radiográfica / Avulsion fractures of the posterior calcaneal tuberosity (beak fracture). functional and radiographic evaluation

Objetivos: Comunicar los resultados funcionales y radiográficos en seis pacientes con fractura "en pico de pato" (beak fracture)y realizar una revisión de la bibliografía.materiales y métodos:Se evaluaron los resultados funcionales (escala de la AOFAS) y radiológicos en seis pacientes (3 hombres y 3 mujeres; edad promedio 35.6 años). El tiempo promedio transcurrido entre la lesión y el ingreso en el quirófano fue de 2.83 h. Se realizó la rama vertical del abordaje lateral extendido. Se fijó con tornillos canulados y macizos de 3,5; 4,0 o 4,5 mm solos o combinados con placas de 3,5 y 2,7 mm bloqueadas.Resultados:Después de un seguimiento de entre 8 y 24 meses, todos los pacientes tenían signos francos de consolidación. Al ingresar, todos presentaban signos de sufrimiento de partes blandas sin signos de necrosis. El puntaje de la escala de la AOFAS fue de 82,4 (5, buenos y 1, regular). Las complicaciones fueron: una infección profunda y pérdida de la reducción en el mismo paciente.Conclusiones:Las fracturas "en pico de pato" pueden generar complicaciones de partes blandas si no son tratadas de manera urgente, debido al compromiso inicial de partes blandas. La reducción abierta y la fijación con tornillos y placas es el sistema de fijación más estable. Nivel de Evidencia: IV

Objectives: To present the functional and radiographic outcomes of six patients with beak fractures and to carry out a literature review. materials and methods: The functional (AOFAS Score) and radiological outcomes of six patients were evaluated. Three patients were male and three were female (mean age: 35.6 years). The mean time interval between injury and admission to the operating room was 2.83 hours. The extensile lateral approach was used. The fracture was fixed with 3.5, 4.0, or 4.5mm cannulated and solid screws alone or in combination with 3.5 and 2.7mm locking plates. Results: After a follow-up period of between 8 and 24 months, all the patients had clear signs of consolidation. On admission, all presented signs of soft tissue pain without signs of necrosis. The AOFAS score was 82.4 (5 good and 1 fair). The complications observed were a deep infection and loss of reduction in the same patient. Conclusions: Beak fractures can generate soft tissue complications if they are not treated urgently due to initial soft tissue involvement. Open reduction and fixation with screws and plates is the most stable fixation system. Level of Evidence: IV

Treatment of Sanders typeⅡto Ⅲ calcaneal fractures with percutaneous reduction and minimally invasive calcaneal screw fixation / 中国骨伤

OBJECTIVE@#To investigate clinical effect of percutaneous reduction combined with internal fixation of calcaneal nail in treating Sanders typeⅡto Ⅲ calcaneal fractures.@*METHODS@#From July 2017 to August 2019, clinical data of 98 patients with Sanders typeⅡto Ⅲ calcaneal fractures treated were retrospectively analyzed, and divided into observation group and control group according to different surgical methods. In observation group, there were 35 males and 21 females, aged from 23 to 58 years old with an average of (34.50±7.81) years old;29 patients with Sanders typeⅡand 27 patients with Sanders type Ⅲ;30 patients on the left side and 26 patients on the right side;the time from fracture to operation ranged from 1 to 4 days with an average of (3.45±0.54) days;and treated with percutaneous reduction combined with internal fixation of calcaneal nail system. In control group, there were 25 males and 17 females, aged from 25 to 60 years old with an average of (35.27±7.64) years old;23 patients with Sanders type Ⅱ and 19 patients with Sanders type Ⅲ;24 patients on the left side and 18 patients on the right side;the time from fracture to operation ranged from 2 to 5 days with an average of (3.42±0.62) days;and treated with open reduction and internal fixation. Operation time, blood loss, hospital stay, fracture healing time, and postoperative visual analogue scale (VAS) at 1 day, preoperative and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Böhler angle, Gissane angle and calcaneus width, and postoperative complications were compared between two groups.@*RESULTS@#All patients were followed up from 13 to 18 months with an average of (15.6±2.2) months. There were significant differences in operation time, blood loss, hospital stay, fracture healing time and postoperative VAS at 1 day between two groups (P<0.05). There was statistical difference in postoperative AOFAS score at 12 months between two groups (P<0.05), and AOFAS score at 12 months after operation was higher than that before operation (P<0.05). According to AOFAS score, 21 patients got excellent result, 30 good and 5 moderate in observation group, and 10 excellent, 22 good, 7 moderate and 3 poor in control group, which had statistical difference between two groups (P<0.05). Postoperative Böhler angle, Gissane angle and calcaneus width at 6 months were better than that before operation between two groups(P<0.05). One patient in observation and 20 patients in control group occurred skin numbness after operation, and 14 patients occurred skin necrosis in control group, there were obvious difference between two groups(P<0.01).@*CONCLUSION@#Compared with open reduction and internal fixation, percutaneous reduction combined with internal fixation system in treating Sanders typeⅡto Ⅲ calcaneal fractures is feasible for fracture repair without waiting for foot deswelling, which could accurately restore normal shape and position of the fractured heel bone, completely eliminate fracture malunion, and reduce postoperative complications. Therefore, it could shorten operation time, hospital stay, fracture healing time, reduce amount of blood loss, promote postoperative recovery, and less complications, high safety, which could be used as a choice of orthopedic surgery for foot and ankle trauma.

Objetivo: Analizar las características demográficas de los pacientes con fracturas articulares de calcáneo en relación con el mecanismo del trauma y los patrones fracturarios según las clasificaciones de Sanders y Essex-Lopresti. materiales y métodos: Se evaluó retrospectivamente a 94 pacientes (111 fracturas articulares de calcáneo). Se analizaron las siguientes variables: edad, sexo, lado fracturado, mecanismo del trauma y lesiones asociadas. Al ingresar, se tomaron radiografías de pie, de frente y perfil, y se realizó una tomografía computarizada con reconstrucción multiplanar. Se analizaron los datos demográficos combinándolos con los tipos de fracturas. Resultados: Se evaluó a 94 pacientes (78 hombres y 16 mujeres) que tenían 105 fracturas intrarticulares de calcáneo (11,7% bilaterales). La edad promedio era de 40.1 ± 12.5 años. El 79,8% de las fracturas se había producido por caída de altura y el 20,1%, por accidente de tránsito. El 9,5% tenía lesiones asociadas. Los pacientes con fracturas bilaterales tenían más lesiones asociadas (p = 0,0123) y el mismo patrón fracturario y tipo de Sanders en ambos pies. No hubo relación entre la clasificación de Sanders y los patrones de Essex-Lopresti con la edad, el sexo y el mecanismo del trauma. Conclusiones: Las fracturas de calcáneo son más frecuentes en hombres y en pacientes jóvenes, y el mecanismo del trauma más común es una caída de altura. Los pacientes con fracturas bilaterales tienen una tasa más alta de lesiones asociadas y el mismo tipo de fractura según la clasificación de Sanders y el patrón fracturario de Essex-Lopresti en ambos pies. Nivel de Evidencia: IV

Objective: To analyze the demographic characteristics of patients with articular calcaneal fractures in connection with trauma mechanisms and fracture patterns, according to the Sanders and Essex-Lopresti classifications. materials and methods: 94 patients and 111 articular calcaneal fractures were evaluated retrospectively, analyzing the following variables: age, gender, fractured side, mechanism of trauma, and associated injuries. The patients were initially evaluated through foot radiographs (anteroposterior and lateral) and axial computerized tomography with multiplanar reconstruction. Demographic data were analyzed combined with the types of fracture. Results: 94 patients (78 men and 16 women) who presented 105 intra-articular calcaneal fractures (11.7% were bilateral) were evaluated. The average age was 40.1±12.5 years. 9.8% of the fractures were caused by high-level falls and 20.1% by traffic accidents. 9.5% had associated injuries. The patients with bilateral fractures presented more associated injuries (p = 0.0123) and the same fracture pattern and Sanders type in both feet. The Sanders classification and Essex Lopresti patterns were unrelated to age, gender, and trauma mechanism. Conclusion: Calcaneal fractures are more frequent in male and young patients, and the most common trauma mechanism is a high-level fall. Patients with bilateral fractures present a higher rate of associated injuries and the same Sanders type fracture and Essex-Lopresti pattern in both feet. Level of Evidence: IV

Objective: To describe functional and radiographic outcomes, and complications of osteosynthesis in calcaneus fractures with the sinus tarsi approach. Materials and Methods: 54 displaced articular calcaneus fractures in 50 patients were assessed through preoperative foot radiographs (anteroposterior and lateral) and computerized tomography. AP and lateral radiographs were obtained in the immediate postoperative period (without weightbearing), after 6 and 12 weeks (with weightbearing), and at the end of follow-up, measuring the Böhler angle and quantifying the degree of subtalar and calcaneocuboid osteoarthritis. The AOFAS score was determined, registering wound complications, neurological injuries and necessary additional surgeries -such as osteosynthesis and subtalar arthrodesis hardware removal. Results: Follow-up time was 30.8 months. The series consisted in 8 women and 42 men. The patients' average age was 39.40±14 years (18-65). There were 40 Sanders type II, 13 type III, and 1 type IV fractures. The AOFAS score was excellent (12 patients), good (25), regular (12), and poor (5). The Böhler angle was 10.8°±10.4° before surgery, and 30.77°±8.24° at the end of follow-up (p<0.00001). 3.7% of the patients presented minor wound complications, while 5.6% presented major wound complications. Conclusion: The sinus tarsi approach allows for acceptable reduction with good and excellent outcomes in most patients, coupled with few soft-tissue complications. Level of Evidence: IV

Colgajo sural reverso más injerto libre en reconstrucción del talón y tobillo / Reverse Sural Flap plus Free Graft in Heel and Ankle Reconstruction

Introducción: Las lesiones traumáticas con pérdida de cobertura cutánea de la región del tobillo y pie, constituyen un gran reto para el cirujano ortopédico por la exposición y destrucción de tejidos nobles, difíciles de solucionar por ser una zona que presenta escaso tejido adiposo, múltiples tendones, poco volumen muscular, varias prominencias óseas y piel poco elástica. Objetivo: Presentar el colgajo sural de flujo reverso como una buena alternativa para tratar la fractura conminuta cerrada de tibia con pérdida masiva de la piel del tobillo y calcáneo en toda su circunferencia, incluida la almohadilla adiposa de la cara plantar. Presentación del caso: Se presenta paciente de 24 años que sufrió accidente de tránsito con fractura conminuta y cerrada de tibia derecha, además de una herida tipo colgajo que dejó expuesto el calcáneo y la región del tobillo. Luego de colocar fijador externo RALCA para fijar la fractura, se realizó colgajo sural en isla de flujo reverso para cubrir el defecto en la cara plantar y posterior del calcáneo, más injerto libre de piel tomado de la cara antero externa del muslo ipsilateral. Estos procedimientos fueron realizados en dos tiempos quirúrgicos. Conclusiones: El colgajo sural de flujo reverso demostró ser una de las mejores alternativas para la cobertura de lesiones desde el tercio medio de la pierna hasta el pie, por lo que debería ser conocido no solo por cirujanos plásticos, sino también por cirujanos ortopédicos y traumatólogos que lo incorporen a su arsenal terapéutico para su realización(AU)

Introduction: Traumatic injuries with loss of skin coverage of the ankle and foot region constitute great challenge for the orthopedic surgeon due to the exposure and destruction of noble tissues, difficult to solve because this area has little adipose tissue, multiple tendons , little muscle volume, several bony prominences and not very elastic skin. Objective: To establish that the reverse flow sural flap is a good alternative to treat closed comminuted fracture of the tibia with massive skin loss of the entire circumference of the ankle and calcaneus, including the plantar face fat pad. Case report: We report the case of a 24-year-old patient who suffered a traffic accident with a comminuted and closed fracture of the right tibia, as well as a flap-type wound that exposed the calcaneus and the ankle region. After placing RALCA external fixator to fix the fracture, a reverse flow island sural flap was made to cover the defect on the plantar and posterior aspect of the calcaneus, and a free skin graft taken from the anterior external aspect of the ipsilateral thigh. These procedures were performed in two surgical stages. Conclusions: The reverse flow sural flap proved to be one of the best alternatives for the coverage of injuries from the middle third of the leg to the foot, which is why it should be known not only by plastic surgeons, but also by orthopedic surgeons and traumatologists and to incorporate this alternative into their therapeutic arsenal(AU)

Luxo-fractura de Chopart / Fracture-luxation de l'articulation de Chopart / Chopart luxo-fracture

La articulación de Chopart o transversa del tarso está constituida por la articulación calcaneocuboidea y la astragaloescafoidea. Las lesiones que ocurren en estas articulaciones se conocen como luxo-fractura de Chopart y son extremadamente raras. Entre las causas más frecuentes se encuentran los accidentes en motocicletas y las caídas de altura. El tratamiento es la reducción anatómica y fijación estable. La necrosis avascular del astrágalo, así como la artritis postraumática son las complicaciones más temidas. Con este trabajo se pretende describir la conducta y evolución perioperatoria de dos pacientes con luxo-fractura de Chopart, atendidos en el Servicio de Urgencias del Hospital Militar Central Dr Luis Díaz Soto. Fueron diagnosticados tempranamente y se les realizó reducción abierta más fijación interna con una recuperación en los primeros tres meses. La baja prevalencia de la luxo-fractura de Chopart requiere un diagnóstico adecuado y correcto para lograr un buen resultado clínico(AU)

The Chopart joint or transverse tarsus is constituted by the calcaneocuboid and the astragaloescafoidea joints. The injuries that occur in these joints are known as Chopart luxo-fracture and are extremely rare. Motorcycle accidents and falls from heights are among the most frequent causes of Chopart luxo-fractures. The treatment is the anatomical reduction and stable fixation. The avascular necrosis of the talus, as well as post-traumatic arthritis are the most feared complications. This paper aims to describe the behavior and perioperative evolution of two patients with Chopart luxo-fracture, treated in the Emergency Service at Dr Luis Díaz Soto Central Military Hospital. They were early diagnosed and underwent open reduction and internal fixation. They recovered in the first three months. The low prevalence of Chopart luxo-fracture requires adequate and correct diagnosis to achieve good clinical results(AU)

L'articulation de Chopart, ou médio-tarsienne, est constituée de deux articulations distinctes: l'articulation calcanéo-cuboïdienne et l'articulation astragalo-scaphoïdienne. Les lésions produites dans ces articulations sont connues comme des fractures-luxations de l'articulation de Chopart, et sont assez rares. Parmi les causes les plus fréquentes, on peut trouver les accidents du trafic (surtout, de moto) et les chutes de haut. Le traitement consiste généralement à une réduction anatomique et une fixation stable. La nécrose avasculaire de l'astragale et l'arthrite post-traumatique sont les complications les plus souvent à craindre. Le but de ce travail est de décrire le comportement et l'évolution péri-opératoire de deux patients atteints d'une fracture-luxation de l'articulation de Chopart, et traités au service d'urgence de l'hôpital militaire Dr Luis Díaz Soto. Ils sont rapidement diagnostiqués, et traités par réduction ouverte et fixation interne. Leur récupération est réussie en trois mois. La faible prévalence de la fracture-luxation de l'articulation de Chopart exige un diagnostic précis pour atteindre de bons résultats cliniques(AU)

Retalho plantar medial: uma série de casos / The medial plantar flap: a case series

Introdução: A cobertura do pé e especialmente da região do calcâneo são desafios técnicos para o cirurgião devido ao alto grau de especialização dos tecidos envolvidos e à relativa imobilidade dos tecidos próximos. Métodos: No presente estudo, apresentamos nossa experiência com uso do retalho baseado na artéria plantar medial para cobertura de defeitos teciduais no pé, especialmente na região de apoio plantar no calcâneo. Doze retalhos da artéria plantar medial feitos de 2001 a 2013 no Hospital Regional da Asa Norte, Brasília, DF, foram incluídos. Resultados: Dos 12 pacientes, 10 eram homens e dois eram mulheres. As indicações foram perda traumática do coxim do calcâneo em 10 pacientes e dorso do pé em dois casos. Todos os retalhos foram elevados como retalhos pediculados fasciocutâneos baseados na artéria plantar medial. Todos os retalhos cicatrizaram sem maiores complicações, exceto um caso com perda parcial. A área doadora foi coberta com enxerto de pele parcial e houve um caso de perda parcial do enxerto. Os retalhos apresentaram uma sensibilidade protetora levemente inferior ao lado normal. Conclusão: De acordo com os resultados, o retalho plantar medial é uma boa opção para cobertura do pé, especialmente do calcâneo. A versatilidade do retalho permite a cobertura de defeitos no calcâneo sobre o tendão de Aquiles e apoio plantar, assim como o dorso do pé. A cobertura da região de apoio plantar com pele de textura similar e sensibilidade protetora confere a esse retalho uma grande vantagem sobre outros retalhos para reconstrução dessa região.

Introduction: Reconstructive coverage of foot defects, especially those of the calcaneus region, is a unique technical challenge for the surgeon due to the high degree of specialization of the tissues involved and the relative immobility of the proximal tissues. Methods: In the present study, we present our experience with the use of the flap based on the medial plantar artery to cover tissue defects in the foot, especially in the region of the calcaneal fat pad. Twelve medial plantar artery flaps constructed from 2001 to 2013 at the As a Norte Regional Hospital, Brasília, DF, were included. Results: Of the 12 patients with the medial plantar artery flaps, 10 were men and 2 were women. The indications were traumatic tissue loss of the plantar fat pad in 10 patients and of the dorsum of the foot in two cases. All flaps were elevated as fasciocutaneous pedicle flaps based on the medial plantar artery. All the flaps healed without major complications, except one case that involved partial loss . The donor area was covered with a partial skin graft and there was one case of partial graft loss. The flap displayed a slightly lower protective sensitivity than the normal side. Conclusion: According to the results, the medial plantar flap is a good option for covering traumatic foot defects, especially those affecting the calcaneus. The versatility of the flap allows the coverage of defects of the calcaneus (e.g., the Achilles tendon and plantar fat pad regions), as well as those affecting the dorsum of the foot. The coverage of the plantar fat pad region with skin of similar texture and protective sensitivity confers to the medial plantar flap a large advantage over other flaps for reconstruction of this region.

Análisis imagenológico del calcáneo aplicada a la fijación interna de fracturas a través del abordaje del seno del tarso / Imaging of the Calcaneus applied to the internal fixation of fractures by a sinus tarsi approach

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.

Comparative study on three surgical techniques for intra-articular calcaneal fractures: open reduction with internal fixation using a plate, external fixation and minimally invasive surgery / Estudo comparativo entre três técnicas cirúrgicas para fraturas intra-articulares de calcâneo: redução aberta e fixação interna com placa, fixação externa e minimamente invasiva

To evaluate, compare and identify the surgical technique with best results for treating intra-articular calcaneal fractures, taking into account postoperative outcomes, complications and scoring in the Aofas questionnaire. METHODS: This was a retrospective study on 54 patients with fractures of the calcaneus who underwent surgery between 2002 and 2012 by means of the following techniques: (1) open reduction with extended L-shaped lateral incision and fixation with double-H plate of 3.5 mm; (2) open reduction with minimal incision lateral approach and percutaneous fixation with wires and screws; and (3) open reduction with minimal incision lateral approach and fixation with adjustable monoplanar external fixator. RESULTS: Patients treated using a lateral approach, with fixation using a plate had a mean Aofas score of 76 points; those treated through a minimal incision lateral approach with screw and wire fixation had a mean score of 71 points; and those treated through a minimal incision lateral approach with an external fixator had a mean score of 75 points. The three surgical techniques were shown to be effective for treating intra-articular calcaneal fractures, without any evidence that any of the techniques being superior. CONCLUSION: Intra-articular calcaneal fractures are complex and their treatment should be individualized based on patient characteristics, type of fracture and the surgeon's experience with the surgical technique chosen.

Avaliar, comparar e identificar a técnica cirúrgica com melhor resultado para o tratamento de fraturas intra-articulares do calcâneo, levando em consideração evolução pós-operatória, complicações e pontuação no questionário Aofas. MÉTODOS: Estudo retrospectivo de 54 pacientes com fraturas de calcâneo operados entre e 2002 e 2012 com as técnicas 1) redução aberta com incisão lateral alargada em "L" e fixação com placa duplo "H" de 3,5 mm, 2) redução aberta por incisão lateral econômica e fixação percutânea com fios e parafusos e 3) redução aberta por incisão lateral econômica e fixação com fixador externo monoplanar regulável. RESULTADOS: Pacientes tratados pela via de acesso lateral e fixação com placa tiveram média de 76 pontos na escala Aofas, em pacientes tratados pela via de acesso lateral econômica e fixação com fios e parafuso a média foi de 71 e nos pacientes tratados com via de acesso lateral e fixador externo foi de 75 pontos. As três técnicas cirúrgicas demostraram-se efetivas no tratamento da fratura intra-articular do calcâneo, sem evidência de superioridade de uma técnica sobre as demais. CONCLUSÃO: A fratura intra-articular do calcâneo é uma fratura complexa e seu tratamento deve ser individualizado, baseado nas características do paciente, no tipo de fratura e na experiência do cirurgião com a técnica operatória escolhida.

Risk of injury to vascular-nerve bundle after calcaneal fracture: comparison among three techniques / Risco de lesão do feixe vasculonervoso após fratura do calcâneo: comparação entre três técnicas

OBJECTIVE: To ascertain whether the number of screws or pins placed in the calcaneus might increase the risk of injury when three different techniques for treating calcaneal fractures. METHOD: 126 radiographs of patients who suffered displaced calcaneal fractures were retrospectively analyzed. Three surgical techniques were analyzed on an interobserver basis: 31 radiographs of patients treated using plates that were not specific for the calcaneus, 48 using specific plates and 47 using an external fixator. The risk of injury to the anatomical structures in relation to each Kirschner wire or screw was determined using a graded system in accordance with the Licht classification. The total risk of injury to the anatomical structures through placement of more than one wire/screw was quantified using the additive law of probabilities for the product, for independent events. RESULTS: All of the models presented high explanatory power for the risk evaluated, since the coefficient of determination values (R2) were greater than 98.6 for all the models. Therefore, the set of variables studied explained more than 98.6% of the variations in the risks of injury to arteries, veins or nerves and can be classified as excellent models for prevention of injuries. CONCLUSION: The risk of injury to arteries, veins or nerves is not defined by the total number of pins/screws. The region and the number of pins/screws in each region define and determine the best distribution of the risk.

OBJETIVO: Verificar se o número de parafusos ou pinos colocados no calcanhar aumentaria o risco de lesão quando usamos três técnicas diferentes para o tratamento das fraturas. MÉTODO: Foram analisadas retrospectivamente 126 radiografias de pacientes que sofreram fratura desviada do calcanhar. Foram analisadas três técnicas cirúrgicas sob a forma interobservador: 31 radiografias de pacientes tratados com placa não específica para o calcanhar, 48 com placa específica e 47 com fixador externo. O risco de lesão das estruturas anatômicas em relação a cada fio de Kirschner ou parafuso foi determinado pelo sistema de graduação segundo a classificação de Licht. A quantificação do risco total de lesão das estruturas anatômicas na colocação de mais de um fio/parafuso foi calculada pela lei aditiva das probabilidades do produto para eventos independentes. RESULTADOS: Todos os modelos apresentaram um alto poder de explicação do risco avaliado, uma vez que os valores do coeficiente de determinação R2 são maiores do que 98,6 para todos os modelos. Portanto, o conjunto de variáveis estudado explica mais de 98,6% das variações dos riscos de lesão das artérias, veias ou dos nervos e podem ser classificados como excelentes modelos para prevenção de lesões. CONCLUSÃO: O risco de lesão das artérias, veias ou dos nervos não é definido pelo total de pinos/parafusos. A região e a quantidade de pinos/parafusos em cada região definem e determinam melhor a distribuição do risco.

Estudo comparativo de artrodese subtalar após fratura de calcâneo com enxerto ósseo ou xenoenxerto liofilizado / Comparative study of subtalar arthrodesis after calcaneal fracture with autologous bone graft or freeze-dried xenograft

Introdução: A fratura viciosamente consolidada do calcâneo pode evoluir com artrose e deformidades graves do pé. O objetivo deste estudo é identifi car diferenças na consolidação da artrodese subtalar corretiva, com interposição de enxerto ósseo tricortical autólogo ou com xenoenxerto bovino liofi lizado. Métodos: Foram avaliados prospectivamente 12 pacientes submetidos a artrodese subtalar no Hospital de Clínicas de Porto Alegre. Em 6 pacientes utilizou-se enxerto autólogo e em 6, xenoenxerto bovino liofilizado. Após seguimento médio de 58 semanas, realizou-se a avaliação dos pacientes utilizando a escala AOFAS e a escala visual analógica de dor (VAD). Dois avaliadores cegos avaliaram o tempo para a consolidação da artrodese e a integração do enxerto por exames radiográficos. Resultado: O escore AOFAS melhorou entre o pré e pós-operatório, média de 37 para 64 pontos (p=0,02) no grupo controle e de 38 para 74 pontos (p=0,02) no grupo estudo. Assim como a escala VAD melhorou, média de 4,7 para 1,9 (p=0,028) no grupo controle e de 5,5 para 2,7 (p=0,046) no grupo estudo. Houve consolidação da artrodese em todos os casos do grupo controle em um tempo médio de 5,3 semanas e em 5 casos do grupo estudo, em 8,8 semanas (p=0,077). A integração do enxerto ocorreu após uma média de 10,7 semanas e de 28,8 semanas no grupo controle e estudo, respectivamente (p=0,016). Conclusão: Não observamos diferença estatisticamente significativa no tempo para consolidação da artrodese entre os grupos, embora o tempo para integração do xenoenxerto bovino liofilizado seja estatisticamente maior. Houve melhora clínico-funcional em ambos os grupos.

Introduction: Viciously consolidated fracture of the calcaneus can evolve with osteoarthritis and severe foot deformities. The aim of this study is to identify differences in the consolidation of corrective subtalar arthrodesis with interposition of autologous tricortical bone graft or lyophilized bovine xenograft. Methods: We prospectively evaluated 12 patients undergoing subtalar arthrodesis in the Hospital de Clínicas of Porto Alegre. In 6 patients we used autologous graft and in other 6 lyophilized bovine xenograft. After a mean follow-up of 58 weeks, patients were evaluated using the AOFAS scale and a visual analogue pain scale (VAPS). Two blinded evaluators assessed the time for consolidation of the arthrodesis and integration of the graft for radiographic examinations. Result: The AOFAS score improved between the pre- and postoperative periods, a mean of 37 to 64 points (p = 0.02) in the control group and 38 to 74 points (p = 0.02) in the experimental group. VAPS scores improved as well, from a mean of 4.7 to 1.9 (p = 0.028) in the control group and 5.5 to 2.7 (p = 0.046) in the experimental group. There was consolidation of arthrodesis in all of the cases in the control group at a median time of 5.3 weeks, and in 5 cases in the experimental group, at 8.8 weeks (p = 0.077). Graft integration occurred after a mean of 10.7 weeks and 28.8 weeks in the control and experimental groups, respectively (p = 0.016). Conclusion: We did not fi nd a statistically signifi cant difference in the time for arthrodesis consolidation between the groups, although the time for integration of the lyophilized bovine xenograft is statistically higher. There was clinical and functional improvement in both groups.

Colgajos en reconstrucción de la región calcánea lateral / Flaps in reconstruction of the lateral calcaneal region: case series and treatment algorithm for soft-tissue complications of the lateral approach for calcaneal fractures

Introduction: Calcaneal fractures are the most frequent tarsal bone fracture. A high complication rate has been reported for the L-shaped lateral calcaneus surgical approach. Coverage of the resulting defect can be challenging. The aim of this article is to report a case series and propose a new treatment algorithm. Materials and Methods: Between January 2011 and December 2013 ninety-five patients underwent a close calcaneus fracture surgery by lateral approach. Ten patients suffered from surgical wound complications. Defects were classified as small (< 2 cm), medium (2-5 cm) or big size (> 5 cm). Results: Small size defects were covered with local fasciocutaneous advancement and rotation flaps. Medium size defect were covered either with a distally based sural neurocutaneous flap or propeller flap based on peroneal artery perforators. A free flap was used in the big size defect presented. Mean follow-up was 16 month (range 5-41 month). Stable coverage was achieved in all cases and no revision surgery was needed. Conclusions: Soft-tissue complications associated to lateral approach for calcaneal fractures needs an ordered approach. The algorithm presented including propeller perforator flaps proved to be safe and useful.

Introducción: Las fracturas de calcáneo son las fracturas más frecuentes de los huesos del tarso. Diversos estudios han mostrado alta tasa de complicaciones del abordaje que requieren cobertura. El objetivo principal es presentar un nuevo algoritmo de tratamiento para estos defectos de cobertura. Material y Métodos: Entre el 2011 y el 2013 se operaron 95 pacientes con fractura cerrada de calcáneo. Diez pacientes presentaron defectos de cobertura de la herida operatoria. Los defectos se clasificaron en pequeños (< 2 cm), medianos (2-5 cm) y grandes (> 5 cm). Resultados: Se realizaron 11 colgajos en 10 pacientes. Seis pacientes presentaron un defecto pequeño y fueron tratados mediante colgajos locales; cuatro casos de defectos medianos se resolvieron mediante tres colgajos perforantes de arteria peronea de tipo propeller y un colgajo sural. Todos los defectos de la zona dadora, tanto en el colgajo sural como en los colgajos propeller, fueron cerrados de manera primaria sin requerir injertos. Hubo un defecto grande que fue necesario cubrir con un colgajo libre. El período de seguimiento promedio fue 16 meses, con un rango de 5 a 41 meses. En todos los casos se proporcionó una cobertura estable que no requirió revisiones. Conclusiones: Es necesario un enfrentamiento ordenado y protocolizado para resolver estos defectos. En nuestro trabajo, proponemos un algoritmo simple basándonos en el ancho del defecto, incorporando como alternativa el colgajo perforante pediculado tipo propeller para defectos medianos, con el cual se logran coberturas estables y planas, con cierre primario de la zona dadora.

Intraoperative Three-Dimensional Imaging in Calcaneal Fracture Treatment

BACKGROUND: To compare the effectiveness of intraoperative three-dimensional (3D) image and conventional two-dimensional (2D) fluoroscopic images, which are used in the treatment of acute calcaneal fractures. METHODS: We retrospectively analyzed 40 patients who suffered calcaneal fracture and underwent surgery at Inje University Busan Paik Hospital. The patients were divided into two groups. Only 2D fluoroscopy was used to evaluate 20 patients of group 1. On the other hand, 3D fluoroscopy was performed on the remaining 20 patients of group 2; 3D fluoroscopy was performed on these patients after they were extensively evaluated by 2D fluoroscopy during surgery. We reviewed the radiographic and clinical outcomes of these patients, whose average follow-up period was 42.6 months. RESULTS: In group 2, 3D fluoroscopy detected four cases (20%) of articular incongruence and screw misplacement. All these complicated cases were corrected during surgery. At the final follow-up session, the mean American Orthopedic Foot and Ankle Society (AOFAS) hind foot score was 78.3 (range, 65 to 95) in group 1 and 82.3 (range, 68 to 95) in group 2. CONCLUSIONS: Intraoperative 3D imaging of calcaneal fractures is considered to be useful in evaluating the congruence of joints and the placement of implants.

Calcanectomia subtotal para tratamento de úlcera de pressão com osteomielite associada: relato de 2 casos / Subtotal calcanectomy for the treatment of calcaneal pressure sores with associated osteomyelitis: a report of 2 cases

Introdução: Feridas em pés são muito frequentes e requerem abordagem multidisciplinar para a sua prevenção, tratamento e reabilitação. Quando acometem o calcâneo, oferecem dificuldade ainda maior e podem apresentar complicação com a ocorrência de osteomielite. Debridamento de tecido desvitalizado e antibioticoterapia são etapas obrigatórias para o tratamento. Na reconstrução, retalhos locais ou livres são necessários. Porém, nem todos os pacientes, devido a condições sistêmicas ou de vascularização local, são candidatos a esse tipo de reconstrução e acabam sendo submetidos a amputações. Relato de caso: Os autores relatam dois casos nos quais foram utilizadas calcanectomias subtotais para o tratamento de feridas em calcâneo. Em ambos os casos, foram evitadas as amputações.

Introduction: Feet wounds are very common and require multidisciplinary approach for prevention, treatment and rehabilitation. When involving the calcaneus, they offer even greater difficulty and may complicate with osteomyelitis. Debridement of devitalized tissue and antibiotics are important steps for treatment. For the reconstruction, local or free flaps are needed. However, not all patients, due to systemic conditions or local blood supply, are not candidates for this type of reconstruction and some times are submitted to amputations. Cases Report: The authors report two cases in which subtotals calcanectomies were used for the treatment of wounds in the calcaneus. In both cases, amputations were avoided.

Resonancia magnética en fractura por estrés de calcáneo / Magnetic resonance imaging in calcaneal stress fractures

Las fracturas por estrés predominan en miembro inferior. Fueron descriptas por primera vez en 1855 antes del descubrimiento de los rayos X. Se encuentran relacionadas a diferentes actividades físicas recreacionales o profesionales. Se producen por sobrecarga repetitiva sobre un hueso con resistencia elástica normal. Las fracturas de estrés del calcáneo son poco frecuentes y consideradas de bajo riesgo. En las imágenes de RM se constató edema de la médula con patrón característico en etapa inicial previo al compromiso de la cortical evidenciable en TC. La RM debe ser la metodología diagnóstica de elección para el diagnóstico de fracturas de estrés del calcáneo en estadía agudo...
