Tratamiento de las fracturas por herida de arma de fuego: revisión bibliográfica sistematizada / Treatment of gunshot wound fractures: systematic review of the literature / Tratamento de fraturas por arma de fogo: revisão bibliográfica sistematizada

Introducción: Las fracturas por heridas de arma de fuego son un motivo de consulta habitual en nuestro país. Existe gran variabilidad de conductas respecto a su tratamiento. El objetivo principal de este trabajo es analizar los distintos tratamientos y sus indicaciones. Materiales: Se realizó una revisión sistematizada de la literatura en las bases de datos Pubmed y Scielo. Se incluyeron artículos con fracturas por herida de arma de fuego en miembros superiores e inferiores, excluyendo la mano. Se analizó: tratamiento (ortopédico o quirúrgico), debridamiento, antibioticoterapia y complicaciones. Resultados: Se obtuvieron 19 artículos que cumplían los criterios de inclusión y exclusión. Los artículos tuvieron un Nivel de Evidencia tipo 2b, 3 y 4. Conclusiones: Los artículos analizados tienen un bajo nivel de evidencia. La fijación quirúrgica es variable y depende de la topografía ósea, la lesión de partes blandas y las lesiones asociadas. El debridamiento profundo está relacionado con mayores índices de infección. Las fracturas estables de tratamiento ortopédico no deberían debridarse ya que aumenta los índices de infección. Debería realizarse antibioticoterapia intravenosa inicial en todos los pacientes, la terapia posterior es discutida.

Introduction: Fractures due to gunshot wounds are a common reason for consultation in our country. There is great variability of conduct regarding its treatment. The main objective of this work is to analyze the different treatments and their indications. Materials: A systematic review of the literature was carried out in the Pubmed and Scielo databases. Articles with fractures due to gunshot wounds in the upper and lower limbs (excluding the hand) were included. We analyzed: treatment (orthopedic or surgical), debridement, antibiotic therapy and complications. Results: 19 articles were obtained that met the inclusion and exclusion criteria. The articles had a Level of Evidence type 2b, 3 and 4. Conclusions: The articles analyzed have a low level of evidence. Surgical fixation is variable and depends on bone topography, soft tissue injury, and associated injuries. Deep debridement is associated with higher rates of infection. Stable orthopedically treated fractures should not be debrided as this increases infection rates. Initial intravenous antibiotic therapy should be performed in all patients, subsequent therapy is discussed.

Introdução: As fraturas por ferimentos por arma de fogo são motivo comum de consulta em nosso país. Há grande variabilidade de conduta quanto ao seu tratamento. O objetivo principal deste trabalho é analisar os diferentes tratamentos e suas indicações. Materiais: Foi realizada revisão sistemática da literatura nas bases de dados Pubmed e Scielo. Foram incluídos artigos com fraturas por arma de fogo em membros superiores e inferiores, excluindo a mão. Foram analisados: tratamento (ortopédico ou cirúrgico), desbridamento, antibioticoterapia e complicações. Resultados: foram obtidos 19 artigos que atenderam aos critérios de inclusão e exclusão. Os artigos tinham Nível de Evidência tipo 2b, 3 e 4. Conclusões: Os artigos analisados ​​apresentam baixo nível de evidência. A fixação cirúrgica é variável e depende da topografia óssea, lesão de tecidos moles e lesões associadas. O desbridamento profundo está associado a maiores taxas de infecção. Fraturas estáveis ​​tratadas ortopedicamente não devem ser desbridadas, pois isso aumenta as taxas de infecção. A antibioticoterapia intravenosa inicial deve ser realizada em todos os pacientes, a terapia subsequente é discutida.

Resultados del tratamiento funcional de las fracturas del metatarso en las fracturas del primer radio / Results of Functional Treatment of Metatarsal Fractures in First Radius Fractures

Introducción: Las fracturas del metatarso son las lesiones traumáticas más comunes del pie, y las del primer metatarsiano son las cuartas en frecuencia. El tratamiento funcional de las fracturas metatarsianas consiste en el apoyo efectivo y precoz, sin inmovilización del miembro. Objetivo: Comparar la efectividad del tratamiento funcional en las fracturas del primer metatarsiano con los tratamientos convencionales Métodos: Se realizó un estudio analítico, observacional, retrospectivo, de casos y controles, en 102 fracturas del primer metatarsiano durante un período de ocho años. La muestra incluyó a pacientes de ambos sexos, entre 16 y 65 años de edad. Se comparó el tratamiento funcional con los tratamientos ortopédico y quirúrgico. Las fracturas fueron clasificadas según su localización, recomendación terapéutica y tratamiento efectuado. Los resultados fueron evaluados en función de la duración de la incapacidad temporal y las complicaciones. Resultados: 48 fracturas fueron tratadas con el método funcional y 41 mediante descarga e inmovilización. Los 13 pacientes con criterio de indicación quirúrgica fueron intervenidos mediante reducción y osteosíntesis. Se obtuvo una menor duración de la incapacidad y menos complicaciones con el tratamiento funcional que con los tratamientos convencionales. Conclusiones: En los últimos años ha aumentado la tendencia a tratar las fracturas metatarsianas de manera conservadora y muchos autores recomiendan el método funcional como tratamiento de elección. Este proporciona una curación más temprana y ocasiona menos complicaciones que los tratamientos convencionales(AU)

Introduction: Metatarsal fractures are the most common traumatic injuries of the foot, and those of the first metatarsal are the fourth in frequency. The functional treatment of metatarsal fractures consists of effective and early support, without limb immobilization. Objective: To compare the effectiveness of functional treatment in fractures of the first metatarsal with conventional treatments. Methods: An analytical, observational, retrospective, case-control study was conducted on 102 first metatarsal fractures over a period of eight years. The sample included patients of both sexes, between 16 and 65 years of age. Functional treatment was compared with orthopedic and surgical treatments. The fractures were classified according to location, therapeutic recommendation and treatment. The results were evaluated according to the duration of the temporary incapacity and the complications. Results: Forty eight fractures were treated with the functional method and 41 by offloading and immobilization. The thirteen patients with surgical indication criteria were operated by reduction and osteosynthesis. A shorter duration of disability and fewer complications were achieved with functional treatment than with conventional treatments. Conclusions: In recent years, the tendency to treat metatarsal fractures conservatively has increased and many authors recommend the functional method as the treatment of choice. This provides earlier healing and causes fewer complications than conventional treatments(AU)

Predictors determining the duration of hospital stay among patients admitted with singlefractures / Predictores que determinan la duración de la estancia hospitalaria en pacientes ingresados con fracturasúnicas

Introduction: Fractures pose a tremendous burden on the health care systems due to the prolonged duration of admission. Addressing various determinants that prolong hospital stay will help minimize the cost of treatment. Objective: To study the determinants associated with the duration of hospital stay among patients admitted with fractures. Methods: This was a retrospective observational study conducted at a private tertiary care hospital in Mangalore. A semi-structured proforma was used for collecting data from the medical records. Results: The mean age of the 124 patients were 48.3±21.4 years. The majority were males [69(55.6 por ciento)] and were from urban areas [86(69.3 por ciento)]. Co-morbidities were present among 69(55.6 por ciento) patients. Out of the total patients, 8(6.4 por ciento) were alcoholics, and 10(8.1 por ciento) were tobacco smokers. The majority [50(40.3 por ciento)] had fracture of the femur. Five (4 por ciento) patients developed complications during the post-operative period. Seventy-eight (62.9 por ciento) patients had medical insurance facilities. The mean duration of hospital stay was 9.6±3.2 days among the patients. The mean duration of hospital stay among patients (n=115) before surgery was 2.4±1.6 days. Increased pre-operative stay, increasing age, rural residential status, open type of fracture, and being given general anaesthesia for the operative procedure were significant predictors determining the period of stay among patients in the hospitals. Alcoholic status independently influenced the period of stay in the pre-operative period. Conclusion: Both patient and treatment characteristics were important determinants associated with the duration of hospital stay. Targeting these predictors will help to manage in-patients better and shorten their duration of hospital stay(AU)

Introducción: Las fracturas suponen una enorme carga para los sistemas sanitarios debido a la duración prolongada del ingreso. Abordar varios determinantes que prolongan la estadía en el hospital ayudará a minimizar el costo del tratamiento. Objetivo: Estudiar los determinantes asociados a la duración de la estancia hospitalaria en pacientes ingresados con fracturas. Métodos: Este es un estudio observacional retrospectivo realizado en un hospital privado de atención terciaria en Mangalore. Se utilizó una proforma semiestructurada para la recolección de datos de las historias clínicas. Resultados: La edad media de los 124 pacientes fue de 48,3±21,4 años. La mayoría eran hombres [69 (55,6 percent)] y de áreas urbanas [86 (69,3 percent)]. Las comorbilidades estuvieron presentes en 69 (55,6 percent) pacientes. Del total de pacientes, 8 (6,4 percent) eran alcohólicos y 10 (8,1 percent) fumadores. La mayoría [50 (40,3 percent)] tenía fractura de fémur. Cinco (4 percent) pacientes desarrollaron complicaciones durante el postoperatorio. Setenta y ocho (62,9 percent) pacientes tenían seguro médico. La duración media de la estancia hospitalaria fue de 9,6±3,2 días entre los pacientes. La duración media de la estancia hospitalaria de los pacientes (n=115) antes de la cirugía fue de 2,4±1,6 días. El aumento de la estancia preoperatoria, el aumento de la edad, el estado residencial rural, el tipo de fractura abierta y la anestesia general para el procedimiento quirúrgico fueron predictores significativos que determinaron el período de estancia entre los pacientes en los hospitales. El estado alcohólico influyó de forma independiente en el tiempo de estancia en el preoperatorio. Conclusión: Tanto las características del paciente como las del tratamiento fueron determinantes importantes asociadas con la duración de la estancia hospitalaria. Abordar estos predictores ayudará a manejar mejor a los pacientes hospitalizados y acortar la duración de su estadía en el hospital(AU)

Principios y recursos clásicos y modernos: combinación en el manejo de fracturas tipo Le Fort / Classical and modern principles and resources: their combination in the management of Le Fort fractures

Introducción: Las lesiones traumáticas maxilofaciales son un problema de salud importante en todo el mundo. Suponen una carga para la salud pública. Objetivo: Reflexionar sobre la necesidad de combinar en el contexto cubano principios y recursos clásicos y modernos en el manejo de fracturas tipo Le Fort. Comentarios principales: El tratamiento de las fracturas faciales ha evolucionado mucho a lo largo de los años. Tradicionalmente, el alambre de acero inoxidable se utilizaba para la osteosíntesis en cirugía maxilofacial hasta la aparición de las miniplacas. Los sistemas de osteosíntesis de titanio son actualmente los de elección en cirugía maxilofacial. A pesar de sus ventajas indiscutibles, en los países en desarrollo ocasionalmente no se cuenta con todo el equipamiento necesario para su empleo. Consideraciones globales: El manejo del trauma maxilofacial se centra en la reobtención de la forma y la función original de la región afectada. Sin vulnerar los principios teóricos de manejo de fracturas tipo Le Fort, se impone de los profesionales cubanos la búsqueda de soluciones en concordancia con la disponibilidad de recursos. La unión de técnicas clásicas y recursos modernos como las suspensiones craneofaciales alámbricas, los arcos barra y los tornillos de fijación maxilomandibular puede ser una alternativa terapéutica confiable(AU)

Introduction: Traumatic maxillofacial lesions are an important global health problem, as well as a public health burden. Objective: Reflect on the need to combine classical and modern principles and resources in the management of Le Fort fractures in the Cuban context. Main remarks: Treatment of facial fractures has evolved considerably through the years. Before the appearance of miniplates, stainless steel wire was used for osteosynthesis in maxillofacial surgery. Titanium osteosynthesis systems are currently the systems of choice in maxillofacial surgery. Despite their undeniable advantages, developing countries occasionally do not have all the equipment required for their use. General considerations: Management of maxillofacial trauma is aimed at recovering the original form and function of the affected area. Without disregarding the theoretical principles of the management of Le Fort fractures, Cuban professionals should search for solutions in keeping with the resources available. The combination of classical techniques and modern resources, such as wired craniofacial suspensions, bar arches and maxillomandibular fixation screws, may be a reliable therapeutic alternative(AU)

Treatment of Metastasis in the Appendicular Skeleton / Tratamento das metástases no esqueleto apendicular

Abstract Bone metastases may evolve with events (pain, fractures and compression) that the orthopedic surgeon will encounter regardless of his subspecialty. Accumulated surgical knowledge is predictive for the prevention of impending fractures, as well as of pathological fractures. We will present a guide to properly evaluate and conduct a patient with bone implant for surgeons who are not specialists in this area.

Resumo As metástases ósseas podem evoluir com eventos (dor, fraturas e compressão) com os quais o cirurgião ortopédico irá se depararar independentemente da sua subespecialidade. Os conhecimentos cirúrgicos acumulados são predicativos para a prevenção de fraturas iminentes, assim como de fraturas patológicas. Apresentaremos um guia para avaliar e conduzir de forma adequada um paciente com implante ósseo para cirurgiões que não sejam especialistas na área.

Monitoring the Progress of Treatment in Fracture Non-Union: The Role of Alkaline Phosphatase and Ultrasonography / Monitoramento da evolução do tratamento da ausência de consolidação da fratura: Papel da fosfatase alcalina e da ultrassonografia

Abstract Objective To evaluate the role of serum alkaline phosphatase (ALP) and ultrasonography (USG) in monitoring the progress of treatment in diaphyseal non-unions. Methods This prospective observational cohort study included adult patients with diaphyseal fractures of major long bones previously treated with internal fixation and eventually resulting in non-union. Following the definitive treatment for non-union, the patients were followed-up periodically for six months, and serial monitoring of the levels of ALP and USG were performed along with radiographs (X-rays) to ascertain the status of the union. Results After an initial rise at seven weeks, ALP levels declined to normal values in fractures which united, whereas they remained high in cases of persistent non-union. Similarly, after an elevation of the vascular resistive index (RI) at around 12 weeks in all the patients, it decreased in cases progressing to union, while it remained persistently high even at 24 weeks in fractures failing to unite. Cases of persistent non-union continued to show hypoechogenic callus at 24 weeks instead of converting into hyperechogenic callus, as observed in cases which progressed to union. Conclusion Significant changes suggestive of union appeared simultaneously on the X-rays, USG and ALP levels during the follow-up. However, a serial examination of the ALP levels and USG during the follow-up gave a hint of the direction of progress in the healing process of fracture non-union. Their role in monitoring the outcome of nonunion is more complimentary than supplementary to the X-rays.

Resumo Objetivo Avaliar o papel da concentração sérica de fosfatase alcalina (FA) e da ultrassonografia no monitoramento do progresso do tratamento da ausência de consolidação em fraturas diafisárias. Métodos Este estudo de coorte observacional prospectivo incluiu pacientes adultos com fraturas diafisárias dos principais ossos longos previamente submetidas a fixação interna sem consolidação. Após o tratamento definitivo, os pacientes foram avaliados periodicamente por seis meses, com realização seriada de ultrassonografia, determinação da concentração de FA e radiografias para verificar a presença de consolidação. Resultados Após um aumento inicial em sete semanas, os níveis de FA voltaram ao valor normal em pacientes com fraturas consolidadas, mas continuaram elevados nos casos de ausência de consolidação. Da mesma forma, após uma elevação do índice de resistência (IR) vascular em cerca de 12 semanas em todos os pacientes, o IR diminuiu nos casos que progrediram para consolidação, mas continuou alto até as 24 semanas em fraturas não consolidadas. Os casos com ausência de consolidação ainda apresentavam calo hipoecogênico às 24 semanas, que não se converteu no calo hiperecogênico observado nos casos que progrediram para consolidação. Conclusão Alterações significativas sugestivas de consolidação foram simultaneamente observadas nas radiografias, na ultrassonografia e na concentração de FA durante o período de acompanhamento. No entanto, a realização seriada de exames da concentração de FA e de ultrassonografia durante o acompanhamento indicou o progresso da consolidação da fratura. Seu papel no monitoramento da ausência de consolidação é mais complementar do que suplementar à radiografia.

Epifisiolisis distal del fémur en un recién nacido / Distal epiphysiolysis of the femur in a newborn

La separación por fractura de la epífisis del fémur distal es una lesión relativamente poco frecuente en los recién nacidos, pero se ha documentado como una complicación del parto distócico. La mayoría de los casos ocurren a nivel distal del húmero y, de manera excepcional, afectan al fémur. La epifisiolisis distal del fémur casi no está descrita en la literatura. Se localizan normalmente en el tercio superior del fémur por un movimiento de torsión de este en los partos en posición podálica e incluso en cesáreas distócicas. El diagnóstico diferencial al inicio de la exploración suele ser con artritis séptica del recién nacido. A partir de un paciente de 3 días de vida que se presenta a su control posterior al alta con tumefacción en una de sus rodillas, se plantea este difícil e infrecuente diagnóstic

Fracture separation of the epiphysis from the distal femur is a relatively rare lesion in newborns, but it has been documented as a difficult complication of labor. Most of the cases occur at the distal humeral level and exceptionally affect the femur. Epiphysiolysis of the distal femur is practically not described. They are normally located in the upper third of the femur due to a twisting movement of the femur in breech deliveries and even in difficult caesarean sections. The differential diagnosis at the beginning of the examination is usually with septic arthritis of the newborn. This difficult and infrequent diagnosis arises from a 3-day-old baby who presents for his post-discharge check-up with swelling in one of his knees.

Treatment of fractures and other orthopedic problems in cats and dogs using versatile external fixator / Tratamento de fraturas de extremidades de cães e gatos usando fixador externo versátil

Many complicated bone fractures can be healed by different techniques including linear external fixation. New generation linear external fixators enhanced the scope of application for bone fractures by mechanical progress. Difficulties include implementing enough pins through fixation clamps to the comminuted fragments or clamp addition and fixing it properly to the rod with the correct pin insertion angle. Effective configurations may not always result. This study sought to reveal the clinical efficiency of modified clamps of a versatile external fixator (VEF) to fix different types of fractures and orthopedic problems according to the radiographic and clinical results. We used this fixator on 17 cats and 17 dogs of different ages and sizes, having different types of antebrachium, humerus, tibia, ulna fractures, and bone-muscle deformities. Clamps had different features to connect fixator pins. Many fixator configurations were created according to the fracture type and body weight of the animals. The most used ones were unilateral and bilateral configurations. The callus formation and visual gait analysis were observed after the operations, until the removal of the fixator. After fixator removal, the visual gait status of the limbs was excellent in 67% of the cases, good in 15%, fair in 12%, and poor in 6%. We found that rods and fixator pins were connected easily by semi-locked clamps. Also, the double pin holding clamps saved space on the fixation rod by the application of two pins through one clamp. We think that clamps of versatile external fixators can easily be constructed to limb fractures and save time during surgery.(AU)

Diversas fraturas ósseas complicadas podem ser tratadas por diferentes técnicas, incluindo fixadores externos lineares. Os fixadores externos lineares de nova geração aumentaram o escopo de aplicação para fraturas ósseas devido ao progresso mecânico. A dificuldade é implementar um número suficiente de pinos através de clamps de fixação aos fragmentos osseos ou adição de clamps com fixação adequadamente à haste com o ângulo correto de inserção do pino. As configurações eficazes nem sempre podem ser realizadas. Este estudo pretendia revelar a eficácia clínica das clamps modificadas de um fixador externo versátil para corrigir diferentes tipos de fraturas e problemas ortopédicos de acordo com os resultados radiográficos e clínicos. O fixador foi utilizado em 17 gatos e 17 cães de diferentes idades e tamanhos, com diferentes tipos de antebraço, úmero, tíbia, fratura de ulna e deformidades ósseo-musculares. Os clamps tinham recursos diferentes para conectar os pinos do fixador. Muitas configurações de fixadores foram criadas de acordo com o tipo de fratura e peso corporal dos animais. As mais utilizadas foram as configurações unilateral e bilateral. A formação do calo e a análise visual da marcha foram observadas após as cirurgias, até a retirada do fixador. Após a retirada do fixador, a utilização dos membros foi excelente em 67% dos casos, bom em 15% dos casos, regular em 12% dos casos, ruim em 6% dos casos. Concluímos que as hastes e os pinos do fixador foram facilmente conectados por clamps semi-travados. Além disso, os clamps de fixação de pino duplo economizaram espaço na haste de fixação com a aplicação de dois pinos em clamp. Acreditamos que os clamps de fixadores externos versáteis podem ser facilmente construídas para fraturas de membros, economizando tempo na cirurgia.(AU)

Reporte de Caso: Fractura esternal / Case report: STERNAL FRACTURE

Sternal fractures are not frequent. There are not many case reports and nowadays, there is not an agreement regarding their treatment. The aim of this report is to present a case in order to contribute clarifying the existing therapeutic proposals. A case of a 45 years-old male patient, who consults because of pain in the anterior region of the chest after a traffic accident is analyzed. The images studies reveal an sternal fracture on the upper third. A surgical approach is proposed but, as the patient refuses it, an ambulatory treatment is made with a satisfactory evolution. Although a surgical treatment was not done, the non surgical management achieved satisfactory results

Fusión occipito-cervical en fractura inestable de atlas tipo Jefferson / Occipito-cervical fusion in unstable fracture of Jefferson type atlas

Resumen Las fracturas del Atlas representan el segundo tipo más común de lesiones de la columna cervical alta. Con este trabajo se persigue describir la fijación occipito-cervical como tratamiento de la fractura de atlas tipo Jefferson inestable. Se presenta paciente que sufre trauma raquimedular, después de aplicarle un minucioso examen físico y la tomografía axial computada de columna cervical se detecta una fractura tipo Jefferson de atlas con más de 7 mm de separación de sus fragmentos. Al ser esta una fractura inestable de la región cervical alta se decide realizar una fijación occipito-cervical como método de tratamiento de esta lesión. La evolución postquirúrgica del paciente transcurrió sin complicaciones (AU).

Summary Atlas fractures represent the second most common type of upper cervical spine injury. This work aims to describe the occipito-cervical fixation as a treatment for the unstable Jefferson-type atlas fracture. A patient suffering from spinal cord trauma is presented, after applying a thorough physical examination and the computed tomography of the cervical spine, a Jefferson type fracture of atlas with more than 7 mm of separation of its fragments is detected. As this is an unstable fracture of the upper cervical region, it was decided to perform an occipito-cervical fixation as a treatment method for this lesion. The postoperative evolution of the patient was uneventful (AU).

Enfoque terapéutico para la fractura atípica de Le Fort I / Therapeutic approach to atypical Le Fort I fracture

ABSTRACT Objective: Describe the clinical management of an atypical Le Fort I fracture case. Case presentation: A 33-year-old patient was brought to the Surgical and Maxillofacial Traumatology Service of Humberto Lucena Senatorial Emergency and Trauma Hospital in Joao Pessoa (PB), Brazil, after undergoing physical aggression. The patient was conscious and lucid. Clinical examination revealed sinking of the middle third of the face with edema and bilateral periorbital ecchymosis. Visual acuity and ocular motricity were preserved in both eyes. A cut-contusion injury on the upper lip, maxillary mobility when handled and discrete occlusal dystopia were also observed. Imaging examination identified a high bilateral Le Fort I fracture. The therapeutic approach chosen was fracture reduction and fixation with plates and screws. After a period of two months, the patient is healing well without any apparent functional or aesthetic alteration. Conclusions: Atypical Le Fort I fractures are not frequent; however, a number of etiologies besides the impact force may bring about them. Treatment should be based on the one for classical Le Fort I fractures with adjustments to the surgical access approach(AU)

RESUMEN Objetivo: Describir los manejos clínicos realizados en una víctima de fractura de Le Fort I atípica. Reporte de caso: Un hombre de 33 años fue llevado al Servicio de Traumatología Quirúrgica y Maxilofacial del Hospital de Trauma y Emergencias Senatorial Humberto Lucena - Joao Pessoa (PB), Brasil, víctima de agresión física. El paciente estaba consciente y lúcido. Clínicamente, se observó hundimiento del tercio medio de su cara con edema y equimosis periorbital bilateral. La agudeza visual y la motricidad ocular se conservaron en ambos ojos. También se observaron herida constuso-cortante en el labio superior, movilidad maxilar cuando se manipula y discreta distopia oclusal. El examen de imagen identificó una fractura bilateral alta de Le Fort I. El enfoque terapéutico elegido fue la reducción de la fractura y la fijación con placas y tornillos. Después de un período de 2 meses, el paciente está evolucionando bien sin aparentes alteraciones funcionales o estéticas. Conclusiones: las fracturas atípicas de Le Fort I no son frecuentes, sin embargo, diferentes etiologías añadidas a la fuerza de impacto pueden justificarlas. El tratamiento debe basarse en las fracturas clásicas de Le Fort I con ajustes en el abordaje de acceso quirúrgico(AU)

Trauma laríngeo externo y fractura de cartílago tiroides: revisión de la literatura / External laryngeal trauma and thyroid cartilage fracture: a literature review

RESUMEN El trauma laríngeo constituye un grupo de lesiones infrecuentes, pero de gran importancia clínica dada su alta morbimortalidad. Requiere un alto nivel de sospecha, puesto que muchas de estas lesiones pueden pasar desapercibidas en la evaluación inicial. Se debe sospechar en todo paciente que se presenta con traumatismo cervical y síntomas que van desde la disfonía y el dolor cervical anterior, a la disnea e incluso el compromiso respiratorio severo por obstrucción de la vía aérea. El abordaje de estos pacientes debe iniciar con la evaluación de la vía aérea y asegurar su estabilidad, para luego enfocarse en el diagnóstico y manejo específico de las lesiones. Presentamos a continuación una revisión bibliográfica en cuanto a los mecanismos de trauma, presentación clínica, diagnóstico, clasificación y manejo.

ABSTRACT The laryngeal trauma constitutes a group of infrequent lesions, but with great clinical importance, given its high morbidity and mortality. It requires a high level of suspicion, since many of these injuries may go unnoticed at the initial evaluation. It should be suspected in every patient presenting with cervical trauma and symptoms ranging from dysphonia and anterior cervical pain, to dyspnea or even severe respiratory distress, due to obstruction of the airway. The approach of these patients should begin with the evaluation of the airway and ensure its stability, to then focus on the diagnosis and specific management of the lesions. We present an updated literature review regarding the mechanisms of trauma, clinical presentation, diagnosis, classification and management.

Intermittent vibrations accelerate fracture healing in sheep

Abstract Purpose: To investigate the effect of intermittent vibration at different intervals on bone fracture healing and optimize the vibration interval. Methods: Ninety sheep were randomized to receive no treatment (the control group), incision only (the sham control group), internal fixation with or without metatarsal fracture (the internal fixation group), and continuous vibration in addition to internal fixation of metatarsal fracture, or intermittent vibration at 1, 2, 3, 5, 7 and 17-day interval in addition to internal fixation of metatarsal fracture (the vibration group). Vibration was done at frequency F=35 Hz, acceleration a=0.25g, 15 min each time 2 weeks after bone fracture. Bone healing was evaluated by micro-CT scan, bone microstructure and mechanical compression of finite element simulation. Results: Intermittent vibration at 7-day interval significantly improved bone fracture healing grade. However, no significant changes on microstructure parameters and mechanical properties were observed among sheep receiving vibration at different intervals. Conclusions: Clinical healing effects should be the top concern. Quantitative analyses of bone microstructure and of finite element mechanics on the process of fracture healing need to be further investigated.

Fracturas desplazadas de epicóndilo medial. Revisión bibliográfica sistematizada / Displaced fractures of medial epicondyle. A systematized bibliographic review / Fraturas com Deslocamento de Epicôndilo Medial. Revisão Bibliográfica Sistematizada

Introducción: la fractura de epicóndilo medial representa 12% a 20% de las fracturas del codo pediátrico. Existe controversia en la indicación del tratamiento para las fracturas con un desplazamiento mayor de 2 mm. El objetivo de este trabajo es revisar la indicación y los resultados de los diferentes tratamientos realizados en las fracturas de epicóndilo medial desplazadas más allá de 2 mm. Material y método: se utilizaron las bases de datos electrónicas PubMed y Bireme. La búsqueda arrojó un total de 313 artículos de los cuales nueve cumplían con los criterios de inclusión propuestos al iniciar la búsqueda. Discusión: se analizaron y compararon los métodos de diagnóstico por imagen utilizados y su rendimiento, los diferentes tipos de tratamiento y las complicaciones. Conclusión: no debe ser el desplazamiento de la fractura lo que guíe el tratamiento sino la energía traumática y la estabilidad en valgo del codo. Se han reportado excelentes resultados tanto con tratamiento conservador como quirúrgico de las fracturas desplazadas de epicóndilo medial. Faltan estudios comparativos con seguimiento a largo plazo de buen nivel de evidencia para recomendar uno u otro tratamiento en las fracturas desplazadas de epicóndilo medial.

Introduction: fractures of medial epicondyle represent 12 to 20% of pediatric elbow fractures. Treating fractures with greater than 2 mm of displacement is a matter of debate. The study aims to review indications and results of the different treatments indicated for fractures of medial epicondyle with greater than 2 mm of displacement. Method: the PubMed and Bireme electronic data bases were used. Search revealed 313 articles, 9 of which met the inclusion criteria set upon initiation of the study. Discussion: imaging techniques used and their diagnostic yield were compared, as well as the different of treatments and complications. Conclusion: treatment should not be defined based on the fracture's displacement, but rather on the trauma energy and the valgus stability of the elbow. Excellent results were reported both with a conservative treatment and with a surgical approach to displaced fractures of medial epicondyle. Comparative studies need to be done with long term follow-up that is well recorded to recommend the right treatment for displaced fractures of medial epicondyle.

Introdução: a fratura de epicôndilo medial representa 12 a 20 % das fraturas do cotovelo em crianças. Existe controvérsia na indicação do tratamento para fraturas com deslocamento superior a 2 mm. O objetivo deste trabalho é revisar a indicação e os resultados dos diferentes tratamentos realizados nos casos de fraturas de epicôndilo medial com deslocamento de mais de 2 mm. Materiais e métodos: foram utilizadas as bases de dados electrónicas PubMed e de Bireme. A pesquisa bibliográfica recuperou 313 artículos sendo que 9 cumpriam com os critérios de inclusão propostos no inicio do trabalho. Discussão: foram analisados e comparados os métodos de diagnóstico por imagem utilizada e seu rendimento, os diferentes tipos de tratamento e as complicações. Conclusão: o deslocamento da fratura não deve ser o determinante do tratamento, mas sim a energia traumática e a estabilidade em valgo do cotovelo. Foram informados resultados excelentes tanto com tratamento conservador como cirúrgico das fraturas com deslocamento de epicôndilo medial. Faltam estudos comparativos com seguimento em longo prazo com evidencias de alta qualidade para recomendar o tipo de tratamento nos casos de fraturas com deslocamento de epicôndilo medial.

Preferences of orthopedic surgeons for treating midshaft clavicle fracture in adults / Preferências dos cirurgiões ortopédicos para o tratamento da fratura do terço médio da clavícula em adultos

ABSTRACT Objective To determine the current clinical practice in Latin America for treating midshaft clavicle fractures, including surgical and non-surgical approaches. Methods A cross-sectional study using a descriptive questionnaire. Shoulder and elbow surgeons from the Brazilian Society of Shoulder and Elbow Surgery and from the Latin American Society of Shoulder and Elbow were contacted and asked to complete a short questionnaire (SurveyMonkey®) on the management of midshaft fractures of the clavicle. Incomplete or inconsistent answers were excluded. Results The type of radiographic classification preferably used was related to description of fracture morphology, according to 41% of participants. Allman classification ranked second and was used by 24.1% of participants. As to indications for surgical treatment, only the indications with shortening and imminence of skin exposure were statistically significant. Conservative treatment was chosen in cortical contact. Regarding immobilization method, the simple sling was preferred, and treatment lasted from 4 to 6 weeks. Although the result was not statistically significant, the blocked plate was the preferred option in surgical cases. Conclusion The treatment of midshaft clavicle fractures in Latin America is in accordance with the current literature.

Métodos Estudo transversal com aplicação de questionário descritivo. Cirurgiões de ombro e cotovelo da Sociedade Brasileira de Cirurgia do Ombro e Cotovelo e da Sociedade Latino-Americana de Ombro e Cotovelo foram contatados e convidados a completar um breve questionário (SurveyMonkey®) sobre o manejo das fraturas do terço médio da clavícula. Foram excluídas as respostas incompletas ou inconsistentes. Resultados O tipo de classificação radiográfica utilizada de preferência esteve de acordo com a descrição da morfologia da fratura, representando 41% do total dos participantes. Em segundo lugar, apareceu a classificação de Allman, que foi utilizada por 24,1% dos participantes. Nas indicações de tratamento cirúrgico, as indicações com encurtamento e iminência de exposição da pele foram estatisticamente significativas. Tratamento conservador foi prescrito em caso de contato entre as corticais. Como método de imobilização, a tipoia simples foi a preferência, e o tempo de tratamento foi de 4 a 6 semanas. Apesar do resultado sem significância estatística, a placa bloqueada foi a opção preferencial nos casos cirúrgicos. Conclusão A metodologia de tratamento das fraturas do terço médio da clavícula nos países da América Latina é semelhante, assim como com a literatura atual.

Matrices de tercera generación en la ingeniería de tejidos ósea / Third-generation matrices in bone tissue engineering

Existen numerosas patologías que generan situaciones invalidantes debido a problemas asociados a nivel de defectos óseos. Esto genera, en muchas oportunidades, cuestiones sanitarias de alto impacto. La ingeniería de tejidos óseos pretende generar propuestas novedosas para reparar pérdidas o fracturas óseas, promoviendo regenerar el tejido mediante el implante de matrices biodegradables que puedan actuar como estructuras para la adhesión celular, favoreciendo el crecimiento y la diferenciación hasta formar hueso de novo. El incremento notable de los conocimientos en las áreas biotecnológicas, de síntesis química, así como de biomedicina, permiten el desarrollo de numerosos tipos de matrices de tercera generación, biodegradables y no tóxicas, con características que proponen sean consideradas en la regeneración tisular ósea. Este trabajo intenta resumir los tipos de matrices que mayor impacto han tenido hasta el momento en la medicina regenerativa ósea, mostrando los casos más relevantes de resultados experimentales y clínicos, y propone algunas perspectivas que se deberían considerar para poder aplicarlas a la práctica clínica. Esta es un área que invita a los investigadores a posicionarse en un pensamiento complejo desde el punto de vista científico-filosófico. (AU)

There are several pathologies that generate disability due to complications associated with bone defects. This often generates high impact health troubles. Bone tissue engineering aims to generate novel means to repair bone loss or bone fractures, promoting tissue regeneration through the implantation biodegradables scaffolds, which can act as structures for cell adhesion, that promts cell growth and differentiation for the novo bone formation. The remarkable for the novo bone formation in biotechnology, chemical synthesis, and biomedical knowledge allows the development of numerous types of third generation scaffolds, applied to promote bone tissue regeneration. This brief report aims to review the scaffolds that have had more impact in bone regenerative medicine so far, describing the most relevant experimental and clinical results. This is an area that invites researchers to situate themselves in a complex thought of scientific-philosophical point of view. (AU)

Tratamiento de las fracturas no articulares de los metacarpianos excluido el primer dedo. Revisión bibliográfica sistematizada / Treatment of non-articular metacarpal fractures excluding thumb

Las fracturas de los metacarpianos constituyen el 10% del total de las fracturas(¹) y representan un 30%-50% de las fracturas de la mano(²). La fractura del cuello del quinto metacarpiano es la más frecuente, también llamada Boxer fracture, corresponde al 20% de todas las fracturas de la mano. Para la gran mayoría de estas fracturas la literatura actual avala el tratamiento conservador, ya que son estables desde el principio o luego de una reducción cerrada(¹). Se calcula que apenas un 5% tienen indicación quirúrgica. El propósito de nuestra revisión bibliográfica fue establecer los diferentes criterios que se utilizan para tratar en forma quirúrgica o no las fracturas no articulares de los metacarpianos excluido el primer dedo. Para ello realizamos una revisión sistematizada de los últimos diez años en mayores de 18 años, obteniendo 19 artículos que cumplían con nuestros criterios de inclusión. Nuestra estrategia de análisis fue revisar las indicaciones terapéuticas, frecuencia y justificaciones. Esta revisión sistematizada se organiza en tres grupos de trabajos, aquellos que se ocupaban del tratamiento ortopédico, los que indicaban el tratamiento quirúrgico y los que comparaban los resultados de ambos tratamientos entre sí. De sus resultados se puede concluir que no existe una indicación quirúrgica universalmente recomendada, ya que la literatura carece de estudios con nivel de evidencia I o II que vayan en esa dirección. De nuestra revisión se extrae cuáles son las indicaciones quirúrgicas más frecuentemente aceptadas en la literatura. Destacándose la angulación dorsal mayor a 30 grados, la malrotación y el acortamiento, los cuales determinan secuelas graves como el crossfinger, la pérdida de extensión o de fuerza de prensión. Finalmente, al no existir un consenso y hasta no contar con la suficiente evidencia científica, la decisión de la estrategia terapéutica recae sobre el cirujano ortopedista, quien debe elegirla según su experiencia, teniendo en cuenta la personalidad de la fractura, los materiales disponibles y la literatura revisada que lo avale.

Abstract Metacarpal fractures constitute 10% of the total number of fractures(1) and they represent 30%-50% of hand fractures(2). Fracture of the fifth metacarpal neck is the most frequent one, also called Boxer fracture, corresponding to 20% of all hand fractures. Literature favors a conservative treatment for most of these fractures, since they are stable from the beginning or after a closed reduction. Our bibliographic review aims to define the different criteria used to treat extra-articular metacarpal fractures excluding the thumb, with or without surgery. To that end, we conducted a systematized review of the last 10 years in patients over 18 years old, obtaining 19 articles that met our inclusion criteria. Our analysis strategy was to review therapy indications, frequency and justification. Systematized revision was divided into three groups of work: those who dealt with orthopedic treatment, those who indicated surgical treatment and those who compared results between the two treatments. Results led to the conclusion that there is no surgical indication that is universally recommended, since literature lacks Level I or II studies on this matter. Our review reveals the most frequently accepted surgical indications in literature. Dorsal angulation exceeding 30 degrees, malrotation and shortening stand out, all of which result in severe sequelae such as crossfinger, loss of extension or grip strength. Last, there being no consensus and until there is enough scientific evidence, decisions on therapeutic strategies are to the orthopedic surgeon, which decision shall be based on their experience, considering the kind of fracture, materials available and reviewed literature that supports it.

Resumo As fraturas dos metacarpianos correspondem a 10% das fraturas em geral(1) e a 30%-50% das fraturas da mão(2). A fratura do colo do quinto metacarpiano, também conhecida como Boxer fracture, é a mais frequente - 20% das fraturas da mão. A literatura atual apoia o tratamento conservador para a grande maioria destas fraturas, pois são estáveis desde o começo ou depois de uma redução fechada(1). Calcula-se que apenas 5% tem indicação cirúrgica. O objetivo desta revisão bibliográfica foi identificar os diferentes critérios utilizados para tratar, cirurgicamente ou não, as fraturas não articulares dos metacarpianos excluindo o primeiro dedo. Realizamos una revisão sistemática da literatura científica dos últimos dez anos que incluíam pacientes maiores de 18 anos; 19 artigos foram selecionados por seguir os critérios de inclusão. A estratégia da análise foi revisar as indicações terapêuticas, frequência e justificativas. Os artigos foram organizados em três grupos: tratamento ortopédico, tratamento cirúrgico e os que comparavam os resultados de ambos os tratamentos. A análise dos resultados mostrou que não se pode concluir que exista una indicação cirúrgica universalmente recomendada, pois a literatura carece de estudos com níveis de evidencia I ou II que considerem esses aspectos. Entre as indicações cirúrgicas mais frequentemente aceitas na literatura se destacam a angulação dorsal maior a 30 graus, má rotação e encurtamento, que determinam sequelas graves como o crossfinger, a perda da extensão ou da força de preensão. Finalmente, como não existe um consenso e enquanto não houver suficiente evidencia científica, a decisão sobre a estratégia terapêutica cabe ao ortopedista, que deve basear-se em sua experiência, considerando as características da fratura, os materiais disponíveis e a literatura disponível.

Urgências em ortopedia / Urgencies in orthopedics

As urgências ortopédicas são recorrentes mesmo nos centros básicos de atenção à saúde. Mesmo que algumas lesões não ofereçam risco imediato à vida do paciente, o tratamento inicial adequado das urgências ortopédicas é vital para afastar o risco de possíveis sequelas, como infecção do ferimento, osteomielite, gangrena, tétano, deformidades, entre outros.

Orthopedic emergencies are recurrent even in the basic health care centers. Even if most injuries offer no immediate life-threatening risk to the patient, the appropriate initial treatment of orthopedic emergencies is vital to avoid the risk of possible sequelae, such as wound infection, osteomyelitis, gangrene, tetanus, deformities, among others.

En cuanto a la recuperación, no se encontró tiempo específico. Conclusiones: el manejo realizado en este centro es acorde a la evidencia actual.

The pelvic fracture in children is rare. Its incidence is 2,4-7.5% of fractures. The mechanism of injury high energy trauma. The diagnosis is made with radiographs and CT pelvis. Treatment can be conservative or surgical, according to age, classification, stability ring, concomitant injuries and hemodynamics. Most are conservative. In this study we describe the management of this condition in the HCSBA SOTI. Materials and Methods :retrospective descriptive study, of 6 patients between 2005-2014, we analyzed: sex, age, mechanism of injury, treatment received, recovery time, complications and follow. Results: 83.3 percent were female, the average age was 11.3 years, the damage occurred by: motor vehicle–pedestrian injury (50 percent), traffic accident (33.3 percent) and fall from height (16.7 percent). The treatments were: conservative (83.3 percent) and surgical (16.7 percent), the march began on average at3.6 weeks, months average follow-up was 5.1; complications were inherent to fracture. Discussion: The literature agrees with the results obtained with respect to age, mechanism of injury and treatment. As for the recovery time is not found specific time. Conclusions: The management held in this center is in line with the current evidence.

Operative versus nonoperative treatment for displaced midshaft clavicle fractures: a meta-analysis based on current evidence

Literature searches of the Cochrane Library, PubMed, EMBASE, Web of Science, LILACS, China National Knowledge Infrastructure, and Wanfang Data databases were performed from 1966 to September 2014. Only randomized and quasi-randomized controlled clinical trials comparing operative and nonoperative treatments for displaced midshaft clavicle fractures were included. Data collection and extraction, quality assessment, and data analyses were performed according to the Cochrane standards. Thirteen studies were considered in the meta-analysis. Constant scores and the Disabilities of the Arm, Shoulder and Hand scores were improved in the operative fixation group at a follow up of one year or more. The nonunion and symptomatic malunion rates were significantly lower in the operative group. Additionally, the nonoperative group had a higher likelihood of neurological symptoms compared with the operative group. A significantly higher risk of complications was found in patients treated conservatively than in those who underwent operative fixation. However, when patients with nonunion and symptomatic malunion were excluded from the analysis, no significant differences in the complication rate were found. We concluded that based on the current clinical reports, operative treatment is superior to nonoperative treatment in the management of displaced midshaft clavicle fractures. However, we do not support the routine use of primary operative fixation for all displaced midshaft clavicle fractures in adults.
