Estimado editor: Los albores del año 2020 le depararon a la humanidad una terrible sorpresa: se reportaban los primeros casos de la posteriormente famosa COVID-19, una enfermedad, cuyo estrepitoso avance la convirtió en una pandemia declarada el 11 de marzo de 2020.1 Desde entonces, muchas han sido las estrategias destinadas a paliar sus efectos deletéreos. Ciertamente, fueron apareciendo esperanzadoras medidas sanitarias, unas con mayor éxito o acogida que otras, pero sin el suficiente respaldo científico como para avalar su uso y convertirse en la estrategia ideal. De ellas, algunas ya validadas para el tratamiento de pacientes críticos, como lo son la ventilación-oxigenoterapia (V), la infusión de líquidos-fluidoterapia (I) y la pronación (P), también fueron parte del intento. A ellas serán dedicadas estas líneas de reflexión...(AU)

Introducción: El tratamiento de los pacientes con insuficiencia respiratoria en el curso de la COVID-19 ha sido un reto en todo el mundo, debido al gran número de pacientes afectados por la agresividad del virus, el empleo de los recursos humanos y la disponibilidad de los equipos. Objetivo: Demostrar la utilidad de la pronación precoz para lograr mejoría de la oxigenación y prevenir en muchos casos la intubación endotraqueal en pacientes con distrés respiratorio por la COVID-19. Métodos: Se realizó un estudio observacional analítico, de corte transversal retrospectivo, de pacientes que ingresaron en la Unidad de Cuidados Intensivos del Hospital Cubano En Qatar, perteneciente a la Hamad Medical Corporation, en el período comprendido de marzo a mayo de 2021. Se utilizaron variables enfocadas en demostrar la respuesta ventilatoria. Se utilizó el paquete estadístico Statistical Package Social Science (Ssps) versión 21.0, según porcentaje y Chi cuadrado, y la t de Student para análisis estadístico deductivo de las muestras relacionadas. Resultados: Predominó el grupo de edades de 3-50 años en pacientes con 2 o más comorbilidades. La oxigenación con HFNC y combinada con NIV fueron las más empleadas. La mayoría de las variables en prueba de muestras relacionadas fueron altamente significativas. Conclusiones: La pronación precoz, como complemento del tratamiento intensivo en pacientes con insuficiencia respiratoria, causada por la enfermedad COVID-19, proporciona una mejor recuperación de los enfermos y una mejoría indiscutibles de los parámetros de ventilación y oxigenación(AU)


Introduction: In the course of COVID-19, the management of patients with respiratory failure has been a challenge worldwide, due to the large number of patients affected by the aggressiveness of the virus, the use of human resources and the availability of equipment. Objective: To show the usefulness of early pronation for improving oxygenation and prevent, in many cases, endotracheal intubation in patients with respiratory failure due to COVID-19. Methods: An analytical, observational, retrospective and cross-sectional study was carried out with patients hospitalized in the intensive care unit of the Cuban Hospital in Qatar, belonging to the Hamad Medical Corporation, in the period from March to May 2021. Variables focused on demonstrating the ventilatory response were used. The Statistical Package Social Science (SPSS), version 21.0, was used, according to percentage and chi-square, as well as Student's t-test for deductive statistical analysis of related samples. Results: The predominant age group was 3-50 years, in patients with two or more comorbidities. Oxygenation with high-flow nasal cannula and combined with non-invasive ventilation were the most widely used. Most of the variables in the related samples test were highly significant. Conclusions: Early pronation, as an adjunct to intensive management of patients with respiratory failure caused by COVID-19, provides better recovery for patients and an indisputable improvement of ventilation and oxygenation parameters(AU)

OBJETIVO Las personas mayores y particularmente las mujeres, son propensas a sufrir traumatismo por caídas. El objetivo de esta investigación fue mejorar la estabilidad y funcionalidad de la pisada en personas mayores, implementando un programa de entrenamiento de musculatura intrínseca del pie, y determinar sus efectos en el riesgo de caída como método de prevención. MATERIALES Y METODOS Participaron 33 personas mayores, de género femenino y autovalentes. En las participantes se evaluó el equilibrio y la velocidad de la marcha con la prueba Time up and Go (TUG), y el equilibrio dinámico se evaluó con la Escala de Tinetti (ET). La intervención constó de enteramiento de tipo short-foot de forma diaria, durante 4 semanas. RESULTADOS los tiempos del TUG disminuyeron de manera progresiva al final de la intervención, lo que indica una optimización en la velocidad de la marcha, por lo que, el entrenamiento tuvo resultados beneficios para la transferencia de carga corporal de una posición sedente a bípedo y de bípedo a marcha. En cambio, para el equilibrio y marcha según ET no se detectó una diferencia significativa. CONCLUSIONES Este entrenamiento presenta una mejoría en el ámbito funcional de cambio de posición, pero no reemplaza el ajuste postural de base de sustentación para mantener el centro de masa en su posición central.


OBJETIVE Seniors, particularly women, are at risk for suffering traumatisms from falls. The objective of this study was to improve the balance and walking functionality of seniors by implementing a program to training the intrinsic muscles of the foot. The impacts of this training on preventing fall risk were assessed. MATERIALS AND METHODS A total of 33 self sufficient, female seniors participated. Balance and the speed of walking were measured using the Timed Up and Go (TUG) test, while balance and gait were measured using the Tinetti Balance and Gait Assessment Tool (TT). Intervention consisted in four weeks of daily short foot exercises. RESULTS The TUG test times decreases progressively from the start to the end of the intervention period, indicating an optimization in walking speed. This translates into beneficial results for the transfer of body load from a sedentary to standing to walking position. In contrast, balance and gait evidenced no significant changes per the TT. CONCLUSIONS The implemented training program improved the functional sphere of position change, but this did not replace the postural adjustments needed in the base of support (i.e. the feet) to maintain a well-positioned center of mass

Contexto: A pandemia da doença do coronavírus (COVID-19) revelou uma miríade de manifestações sistêmicas e cutâneas possivelmente relacionadas à infecção por síndrome respiratória aguda grave ocasionada pelo coronavírus (SARS-CoV-2). O comprometimento pulmonar é a causa mais frequente de hospitalização e a progressão para síndrome respiratória aguda grave geralmente requer tratamento com ventilação mecânica na posição pronada. Períodos prolongados e repetidos de pronação aumentam o risco de complicações, incluindo úlcera de pressão, cegueira e neuropatia periférica. Descrição do caso: Relatamos três casos de complicações cutâneas relacionadas à ventilação em pronação avaliadas durante interconsultas no maior hospital terciário universitário da América Latina, e salientamos potenciais causas e medidas de prevenção. Discussão: Complicações da ventilação em pronação para tratamento da COVID-19 são provavelmente resultantes da interação entre múltiplos fatores, dentre os quais as condições clínicas do paciente, períodos prolongados na posição pronada e limitações para mudanças de decúbito. Conclusões: Medidas de prevenção para complicações da pronação e diagnóstico precoce são fundamentais para evitar aumento da morbidade e sequelas graves e irreversíveis associadas à COVID-19.

Introdução: A síndrome da angústia respiratória (SARA), causada pelo novo coronavírus (SARS-CoV-2), surgiu em 2019 e rapidamente desencadeou uma pandemia, resultando em milhares de mortes em diversos países. No tratamento dos casos graves, em que a hipoxemia e a insuficiência respiratória estão presentes, é necessário utilizar ventilação mecânica invasiva, como estratégia de compensação. Além disso, o suporte ventilatório auxilia na melhora da oxigenação e trocas gasosas, aumentando os níveis alveolares e, por conseguinte, melhorando a oxigenação. Destaca-se que a prevenção da ocorrência de eventos adversos é um desafio constante quando se trata da COVID-19. Objetivo: Sintetizar as evidências científicas sobre a prevalência de eventos adversos na pronação de pacientes adultos e idosos entubados com COVID-19. Método: Revisão sistemática com meta-análise, realizada nas bases de dados Cochrane Library, Cinahl, Embase, Lilacs, Livivo, PubMed, Scopus e Web of Science, incluindo estudos observacionais de pacientes adultos e idosos com COVID-19 em ventilação mecânica tanto com o tubo orotraqueal quanto por traqueostomia, em posição prona. Dois revisores avaliaram independentemente os estudos e extraíram os dados. O terceiro revisor foi contatado em todas as fases, para resolução dos conflitos. Os estudos foram meta-analisados com auxílio do software JAMOVI 1.6.15. Utilizou-se um modelo de efeito randômico para identificar a prevalência global dos eventos adversos, o intervalo de confiança e os dados de heterogeneidade. O risco de viés foi avaliado com base na ferramenta Joanna Briggs Institute e a certeza da evidência mediante a aplicação da abordagem Grading of Recommendations Assessment, Development and Evaluation (GRADE). Resultados: Dos 7904 estudos identificados nas buscas, após leitura de título e resumos e resolução de conflitos, 169 foram incluídos para leitura na íntegra e, após, 10 incluídos na revisão. Os eventos adversos mais prevalentes em paciente ventilados mecanicamente pronados são: lesões por pressão, com prevalência global de 59%, presença de instabilidade hemodinâmica (23%), óbito (17%), perda ou tracionamento de dispositivo (9%). Conclusão: Eventos adversos causam lesões por vezes evitáveis, sendo que algumas delas geram sequelas permanentes, com impacto negativo na qualidade de vida do paciente acometido e de sua família. Investigar eventos adversos é o caminho para promover melhorias na qualidade e segurança dos pacientes e, a partir disso, padronizar protocolos e rotinas nacionais e internacionais para realizar a pronação e manutenção deste em prona com foco na prevenção desses eventos


Introduction: Respiratory distress syndrome (ARDS), emerged in 2019, caused by the new coronavirus (SARS-CoV-2), triggered a pandemic, resulting in hundreds of deaths in several countries. In severe cases of COVID-19, where hypoxemia and respiratory failure is present, it is necessary to use invasive mechanical ventilation, as a compensation strategy and ventilatory support helps to improve oxygenation and gas exchange and increase alveolar levels, and consequent improvement in oxygenation. Preventing the occurrence of adverse events is a constant challenge in the face of COVID-19. Objective: To synthesize the evidence on the prevalence of adverse events in pronation in adult and elderly patients intubated with COVID-19. Method: Systematic review with meta-analysis, performed in the following databases: Cochrane Library, Cinahl, Embase, Lilacs, Livivo, PubMed, Scopus and Web of Science, including observational studies of adult and elderly patients with COVID-19 on mechanical ventilation with both the orotracheal tube and tracheostomy, submitted to prone position. Two reviewers independently assessed the studies and extracted data, the third reviewer was contacted at all stages for conflict resolution. The studies were meta-analyzed using JAMOVI 1.6.15 software. Random effect model was used to identify the prevalence of adverse events, identifying the overall prevalence of events, confidence interval, and heterogeneity data. The risk of bias was assessed using the Joanna Briggs Institute tool and the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Of the 7904 studies identified in the searches, after reading the title and abstracts, conflict resolution, 169 studies were included for full reading, and 10 included in the review. The most prevalent adverse events in mechanically ventilated pronated patients are pressure injuries with an overall prevalence of 59%, presence of hemodynamic instability 23%, death 17%, device loss or traction 9%, edema, polyneuropathy, plexus injuries and eye injury. Conclusion: Adverse events cause injuries that are sometimes preventable, some of which generate permanent sequelae, generating a negative impact on the quality of life of this affected patient and his family. Carrying out the investigation of adverse events is the way to promote improvements in the quality and safety of patients and, from that, standardize international protocols and routines to perform pronation and maintenance of the patient in prone, focusing on the prevention of adverse events

Justificativa e objetivos: Na busca de estratégias para o tratamento da insuficiência respiratória aguda causada pela COVID-19, surge a ventilação não invasiva (VNI) e o uso da posição prona em respiração espontânea. Objetiva-se apresentar o caso de uma paciente com COVID-19 grave admitida em unidade de terapia intensiva (UTI) e submetida à máscara de mergulho adaptada, que se configura em uma interface inovadora para VNI, bem como a posição prona. Métodos: Relato de caso de paciente hospitalizado diagnosticado com COVID-19 submetido à VNI precoce por meio da máscara de mergulho adaptada e uso da posição prona em respiração espontânea por 8 horas noturnas e 6 horas diurnas. Resultados: Paciente do sexo feminino, 56 anos, hipertensão arterial sistêmica e obesidade, apresentando tosse seca, odinofagia, fadiga e dispneia intensa na admissão. A tomografia de tórax demonstrou opacidades em vidro fosco bilaterais. A VNI foi instituída 1-2,75 vezes/dia, por 40-60 minutos, com pressão positiva ao final da expiração de 8 (7,25-8,00) cmH2O e pressão de suporte de 5,5 (4,00-6,00) cmH2O. Fuga aérea de 6 a 30%, com boa tolerância. A posição prona em respiração espontânea resultou em aumento da saturação periférica de oxigênio e redução do desconforto respiratório 30 minutos após. Conclusão: A associação do uso da VNI com máscara de mergulho adaptada e posição prona em respiração espontânea demonstrou ser eficaz em evitar a intubação orotraqueal de paciente com COVID-19 grave, ressaltando a importância da intervenção proposta.(AU)

Abstract Introduction: Excessive pronation has been linked to increased risk of developing lower limb injuries. In this respect, assessing the effectiveness of therapeutic resources, such as hyperelastic taping, becomes relevant. Objective: evaluate the influence of adhesive hyperelastic taping on excessive pronation of the ankle-foot complex in young women. Method: Self-controlled clinical trial of ten women with excessive pronation (Foot Posture Index ≥ 6). Three-dimensional gait was assessed according to the Vicon Oxford Foot Model before and after taping. Hyperelastic tape was applied on the side with greater pronation (experimental side) and the opposite side was used as control (control side). The segments evaluated were the hindfoot, midfoot and forefoot. The Shapiro-Wilk normality, paired t and Wilcoxon tests were applied and Significance was set at p <0.05. Results: No change (p> 0.05) was observed in the hindfoot on the experimental or control side; the midfoot showed a decrease in arch height (p <0.05) only on the experimental side; forefoot eversion (p <0.05) declined only on the experimental side. Conclusion: The use of hyperelastic tape reduced forefoot eversion; however, this decrease is not clinically desirable, since excessive pronation in a closed chain increased in the sample of young women studied.


Resumo Introdução: A pronação excessiva tem sido relacionada ao aumento do risco de desenvolver lesões nos membros inferiores. Nesse sentido, verificar a efetividade de recursos terapêuticos, como a bandagem hiperelástica, tornou-se relevante. Objetivo: Avaliar a influência da bandagem hiperelástica na pronação excessiva do pé em mulheres jovens. Método: Ensaio clínico autocontrolado, no qual participaram dez mulheres com pronação excessiva (Foot Posture Index ≥ 6). Realizou-se então a avaliação tridimensional da marcha de acordo com o modelo Oxford Foot Model da Vicon em dois momentos: antes e após a bandagem. Foi aplicada bandagem hiperelástica no lado com maior pronação (lado experimental) e o lado oposto foi utilizado como controle (lado controle). Quanto aos segmentos avaliados, estes foram o retropé, antepé e mediopé. Para análise dos dados aplicou-se o teste de normalidade Shapiro Wilk, testes t pareado e Wilcoxon. E o nível de significância foi considerado como p<0,05. Resultados: No retropé não foi verificada mudança (p>0,05) no lado experimental ou controle; no mediopé foi observado redução da altura do arco (p<0,05) somente no lado experimental, porém sem diferença entre grupos (p>0,05); e no antepé foi observado redução da eversão (p<0,05) somente no lado experimental. Conclusão: A aplicação utilizada de bandagem hiperelástica reduziu a eversão do antepé, porém essa redução não é desejável clinicamente, uma vez que em cadeia fechada a pronação excessiva aumenta na amostra de mulheres jovens estudadas.

Introdução: o posicionamento de pacientes adultos em estado crítico em prona é uma medida assistencial na abordagem aos pacientes com Síndrome do Desconforto Respiratório Agudo (SDRA). O Proning Severe ARDS Patients (PROSEVA) demonstrou a redução pela metade da taxa de mortalidade em pacientes com formas graves de SDRA posicionados em prona de forma precoce e prolongada quando comparada a posição supina. Considerando a definição de segurança do paciente é estabelecida pela Organização Mundial de Saúde (OMS) como a redução do risco de dano desnecessário associado ao cuidado de saúde, ao mínimo necessário, emerge a necessidade de treinamento das equipes e uniformização das ações para reconhecer, mensurar e minimizar os riscos para ocorrência de eventos adversos (EAs) e otimizar os resultados terapêuticos da pronação Objetivos: desenvolver uma escala de risco para pronação de pacientes adultos em estado crítico; identificar os EAs/complicações mais recorrentes descritos na literatura relacionados à pronação de pacientes adultos em estado crítico; construir a escala de risco para pronação de pacientes adultos em estado crítico; e validar o conteúdo da escala de risco para pronação de pacientes adultos em estado crítico. Método: estudo metodológico desenvolvido em três etapas: revisão integrativa de literatura sobre a recorrência de eventos adversos/complicações associados à pronação de pacientes adultos em estado crítico, construção e validação de conteúdo da Escala de Risco para Pronação de Pacientes Adultos em Estado Crítico. A avaliação da escala quanto ao nível de adequação de seu conteúdo foi realizada por 17 juízes. Para validação foi utilizado o Índice de Validação de Conteúdo (IVC) com valor mínimo de 0,78. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa (CEP) da instituição proponente (Universidade Federal do Estado do Rio de Janeiro ­ UNIRIO), número do Parecer: 2.319.199. Resultados: Foram produzidos três produtos, sendo dois estruturados sob a forma de artigo e um instrumento de segurança intitulado de Escala de Risco para Pronação de Pacientes Adultos em Estado Crítico validada com equivalência entre os parâmetros quanto ao potencial de risco validado. O instrumento obteve IVC global de 0,94. Conclusão: a Escala de Risco para Pronação de Pacientes Adultos em Estado Crítico é um instrumento válido para mensuração dos riscos para a ocorrência de EAs/complicações resultantes da pronação e pode estimular e difundir a utilização desta estratégia terapêutica no cenário da assistência de alta complexidade


Introduction: The positioning of critically adult patients in prone position is an assistance measure in the approach to patients with Acute Respiratory Distress Syndrome (ARDS). The Proning Severe ARDS Patients (PROSEVA) demonstrated a halving of the mortality rate in patients in prone position with severe forms of ARDS precociously and prolonged when compared to the supine position. Considering the definition of patient safety is established by the World Health Organization (WHO) as reducing the risk of unnecessary damage associated with health care, to the minimum necessary, emerges the need for training of the teams and standardization of actions to recognize, measure and to minimize the risks for the occurrence of adverse events (AEs) and to optimize the therapeutic results of pronation. Objectives: to develop a risk scale for pronation of critically ill adult patients; to identify the most recurrent AEs / complications described in the literature related to the pronation of critically adult patients; to construct the risk scale for pronation of critically adult patients; and validate the content of the risk scale for pronation of critically adult patients. Method: methodological study developed in three stages: integrative review of literature on the recurrence of adverse events / complications associated with the pronation of adult patients in critical state, construction and validation of content of the Scale of Risk for Pronation of Adult Patients in Critical State. The evaluation of the scale regarding the adequacy of its contents was carried out by 17 judges. For validation, the Content Validation Index (CVI) with a minimum value of 0.78 was used. This study was approved by the Research Ethics Committee (CEP) of the proposing institution (Federal University of the State of Rio de Janeiro - UNIRIO), opinion number: 2,319,199. Results: Three products were produced, two structured in the form of an article and a safety instrument titled Risk Scale for Pronation of Adult Patients in Critical State validated with equivalence between the parameters regarding the validated risk potential. The instrument obtained a global CVI of 0.94. Conclusion: The Risk Scale for Pronation of Adult Patients in Critical State is a valid instrument for measuring the risks for the occurrence of AEs / complications resulting from pronation and can stimulate and diffuse the use of this therapeutic strategy in the scenario of high complexity care

ABSTRACT Objective: The goal of this study was to describe anatomical variations and clinical implications of anterior interosseous nerve. In complete anterior interosseous nerve palsy, the patient is unable to flex the distal phalanx of the thumb and index finger; in incomplete anterior interosseous nerve palsy, there is less axonal damage, and either the thumb or the index finger are affected. Methods: This study was based on the dissection of 50 limbs of 25 cadavers, 22 were male and three, female. Age ranged from 28 to 77 years, 14 were white and 11 were non-white; 18 were prepared by intra-arterial injection of a solution of 10% glycerol and formaldehyde, and seven were freshly dissected cadavers. Results: The anterior interosseous nerve arose from the median nerve, an average of 5.2 cm distal to the intercondylar line. In 29 limbs, it originated from the nerve fascicles of the posterior region of the median nerve and in 21 limbs, of the posterolateral fascicles. In 41 limbs, the anterior interosseous nerve positioned between the humeral and ulnar head of the pronator teres muscle. In two limbs, anterior interosseous nerve duplication was observed. In all members, it was observed that the anterior interosseous nerve arose from the median nerve proximal to the arch of the flexor digitorum superficialis muscle. In 24 limbs, the branches of the anterior interosseous nerve occurred proximal to the arch and in 26, distal to it. Conclusion: The fibrous arches formed by the humeral and ulnar heads of the pronator teres muscle, the fibrous arch of the flexor digitorum superficialis muscle, and the Gantzer muscle (when hypertrophied and positioned anterior to the anterior interosseous nerve), can compress the nerve against deep structures, altering its normal course, by narrowing its space, causing alterations longus and flexor digitorum profundus muscles.


RESUMO Objetivo: Analisar as relações anatômicas e as variações do nervo interósseo anterior e suas implicações clínicas. A paralisia completa do nervo interósseo anterior resulta na incapacidade de fletir as falanges distal do polegar e indicador; na incompleta, ocorre menor dano axonal e apenas o polegar ou o indicador são afetados. Método: Este estudo baseou-se na dissecção de 50 membros de 25 cadáveres, 22 eram do sexo masculino e três do feminino. A idade variou entre 28 e 77 anos, 14 da etnia branca e 11 não branca; 18 foram preparados por injeção intra-arterial de uma solução de glicerina e formol a 10% e sete foram dissecados a fresco. Resultados: O nervo interósseo anterior originou-se do nervo mediano em média de 5,2 cm distal à linha intercondilar. Em 29 membros, originou-se dos fascículos nervosos da região posterior do nervo mediano e em 21 membros, dos fascículos posterolaterais. Em 41 membros, o nervo interósseo anterior posicionava-se entre as cabeças umeral e ulnar do músculo pronador redondo. Em dois membros, observou-se a duplicação do nervo interósseo anterior. Em todos os membros, registramos que o nervo interósseo anterior se desprendia do nervo mediano proximalmente à arcada do músculo flexor superficial dos dedos. Em 24 antebraços a ramificação do nervo interósseo anterior ocorreu proximalmente à arcada do músculo flexor superficial dos dedos em 26, distalmente. Conclusão: As bandas fibrosas formadas pelas cabeças umeral e ulnar do músculo pronador redondo, a arcada fibrosa do músculo flexor superficial dos dedos e o músculo de Gantzer, quando hipertrofiado e posicionado anteriormente ao nervo interósseo anterior, podem comprimir o nervo contra estruturas profundas, alterar seu curso normal, por estreitar o espaço de sua passagem, causar alterações no músculo flexor longo do polegar e no flexor profundo dos dedos da mão.

Malignant peripheral nerve sheath tumor (MPNST) is a very rare type of sarcoma, with an incidence of 0.001%. MPNST has a 5-year survival rate near 80%, so successful reconstruction techniques are important to ensure the patient's quality of life. Sarcoma of the forearm is known for its poor prognosis, which leads to wider excision, making reconstruction even more challenging due to the unique anatomical structure and delicate function of the forearm. A 44-year-old male presented with a large mass that had two aspects, measuring 9×6 cm and 7×5 cm, on the dorsal aspect of the right forearm. The extensor compartment muscles (EDM, EDC, EIP, EPB, EPL, ECRB, ECRL, APL) and invaded radius were resected with the mass. Tendon transfer of the entire extensor compartment with skin defect coverage using a 24×8 cm anterolateral thigh (ALT) perforator free flap was performed. The patient was discharged after 18 days without wound complications, and has not complained of discomfort during supination, pronation, or wrist extension/flexion through 3 years of follow-up. To our knowledge, this is the first report of successful reconstruction of the entire forearm extensor compartment with ALT free flap coverage after resection of MPNST.

BACKGROUND: A variety of treatment options suggest that the optimal treatment strategy for lateral elbow tendinopathy (LET) is not known, and further research is needed to discover the most effective treatment for LET. The purpose of the present study was to verify the most effective position of eccentric stretching for the extensor carpi radialis brevis (ECRB) in vivo using ultrasonic shear wave elastography. METHODS: A total of 20 healthy males participated in this study. Resting position was defined as 90° elbow flexion and neutral position of the forearm and wrist. Elongation of the ECRB was measured for four stretching maneuvers (forearm supination/pronation and wrist extension/flexion) at two elbow angles (90° flexion and full extension). The shear elastic modulus, used as the index of muscle elongation, was computed using ultrasonic shear wave elastography for the eight aforementioned stretching maneuverangle combinations. RESULTS: The shear elastic modulus was the highest in elbow extension, forearm pronation, and wrist flexion. The shear elastic moduli of wrist flexion with any forearm and elbow position were significantly higher than the resting position. There was no significant difference associated with elbow and forearm positions except for elbow extension, forearm pronation, and wrist flexion positions. CONCLUSIONS: This study determined that elbow extension, forearm pronation, and wrist flexion was the most effective eccentric stretching for the ECRB in vivo.

BACKGROUND: The location of the ulnar styloid process can be confusing because the radius and the hand rotate around the ulna. The purpose of this study was to identify the absolute location of the ulnar styloid process, which is independent of forearm pronation or supination, to use it as a reference for neutral forearm rotation on lateral radiographs of the wrist. METHODS: Computed tomography (CT) images of 23 forearms taken with elbow flexion of 70° to 90° were analyzed. The axial CT images were reconstructed to be perpendicular to the distal ulnar shaft. The absolute location of the ulnar styloid process in this study was defined as the position of the ulnar styloid process on the axial plane of the ulnar head relative to the long axis of the humeral shaft with the elbow set in the position for standard lateral radiographs of the wrist. To identify in which direction the ulnar styloid is located on the axial plane of the ulnar head, the angle between “the line of humeral long axis projected on the axial plane of the ulna” and “the line passing the center of the ulnar head and the center of the ulnar styloid” was measured (ulnar styloid direction angle). To identify how volarly or dorsally the ulnar styloid should appear on the true lateral view of the wrist, the ratio of “the volar-dorsal diameter of the ulnar head” and “the distance between the volar-most aspect of the ulnar head and the center of the ulnar styloid” was calculated (ulnar styloid location ratio). RESULTS: The mean ulnar styloid direction angle was 12° dorsally. The mean ulnar styloid location ratio was 1:0.55. CONCLUSIONS: The ulnar styloid is located at nearly the ulnar-most (the opposite side of the humerus with the elbow flexed) and slightly dorsal aspects of the ulnar head on the axial plane. It should appear almost midway (55% dorsally) from the ulnar head on the standard lateral view of the wrist in neutral forearm rotation. These location references could help clinicians determine whether the forearm is in neutral or rotated position on an axial CT/magnetic resonance imaging scan or a lateral radiograph of the wrist.

PURPOSE: The purpose of this study was to evaluate the radiological and clinical results of plate fixation and external fixation with additional devices for treating distal radius fracture in AO type C subtypes, and propose a treatment method according to the subtypes. MATERIALS AND METHODS: Two hundred and one AO type C distal radius fracture patients were retrospectively reviewed. Eighty-five patients in group 1 were treated with volar or dorsal plate, and 116 patients in group 2, were treated with external fixation with additional fixation devices. Clinical (range of mtion, Green and O'Brien's score) and radiological outcomes were evaluated. RESULTS: At the 12-month follow-up, group 1 showed flexion of 64.4°, extension of 68.3°, ulnar deviation of 30.6°, radial deviation of 20.8°, supination of 76.1°, and pronation of 79.4° in average; group 2 showed flexion of 60.5°, extension of 66.9°, ulnar deviation of 25.5°, radial deviation of 18.6°, supination of 73.5°, and pronation of 75.0° in average. The mean Green and O'Brien score was 92.2 in group 1 and 88.6 in group 2. The radial height of group 1 and group 2 was 11.6/11.4 mm; radial inclination was 23.2°/22.5°; volar tilt was 11.6°/8.7°; and the ulnar displacement was 1.27/0.93 mm. CONCLUSION: Judicious surgical techniques during device application and tips for postoperative management during external fixation can produce similar clinical results compared with internal fixation patients.

Abstract Several studies have investigated the relationship between heel pronation with plantar pressure during gait. With a degree of variability and influence of the footwear, usually excessive pronation is associated with higher mechanical loads. However, larger loads are commonly associated with pronation. his study aims to compare the plantar pressure distribution among individuals with different pronation angles of the subtalar joint angle during gait with controlled speed. he maximum angle of the subtalar joint was determined by capturing images in the frontal plane and the pressure plant peaks were acquired by EMED pressure platform. he pronated group showed pressure plant peaks significantly higher in the lateral heel area (18%; p=0.031), medial heel (17%, p=0.034), lateral midfoot (30%; p=0.032) and medial midfoot (41%; p=0.018) when compared to the control group. Excessive pronation of the subtalar joint caused changes in plantar pressure distribution, and an increase in pressure plant peaks, especially in the heel and midfoot regions. This demonstrates the need for a specific care of this population, mainly because the increased pressure plant peaks is related to pain in the feet and onset of injuries.


Resumo Diversos estudos investigaram a relação da pronação da articulação subtalar com a pressão plantar na marcha. Com certo grau de variabilidade e influência do calçado, geralmente uma pronação excessiva está associada a cargas mecânicas mais elevadas. Contudo, popularmente se associa qualquer índice de pronação com aumento das cargas. Neste estudo buscamos comparar a distribuição de pressão plantar entre indivíduos com diferentes comportamentos do ângulo de pronação da articulação subtalar durante a marcha com velocidade controlada. O ângulo máximo de pronação da articulação subtalar foi determinado por meio da aquisição de imagens no plano frontal e os picos de pressão plantar foram adquiridos através da plataforma de pressão EMED. O grupo pronado apresentou picos de pressão plantar significativamente mais elevados na região do calcanhar lateral (18%; p=0,031), do calcanhar medial (17%, p=0,034), do mediopé lateral (30%; p=0,032) e do mediopé medial (41%; p=0,018) quando comparado ao grupo controle. A excessiva pronação da articulação subtalar provocou alterações na distribuição de pressão plantar, com aumento nos picos de pressão plantar, principalmente nas regiões do calcanhar e do mediopé. Isto demonstra a necessidade de um cuidado especifico em relação e este público, principalmente pelo aumento dos picos de pressão plantar estar relacionado com dores nos pés e com o surgimento de lesões.

ABSTRACT OBJECTIVE: To assess the anatomical variations of the pronator teres muscle (PTM) and its implication in the compression of the median nerve, which passes through the humeral and ulnar heads of the PTM. METHODS: For the present study, 100 upper limbs from human cadavers from the anatomy laboratory were dissected. Forty-six specimens were male and four, female, whose aged ranged from 28 to 77 years; 27 were white and 23, non-white. A pilot study consisting of six hands from three fresh cadaver dissections was conducted to familiarize the authors with the local anatomy; these were not included in the present study. RESULTS: The humeral and ulnar heads of PTM were present in 86 limbs. In 72 out of the 86 limbs, the median nerve was positioned between the two heads of the PTM; in 11, it passed through the muscle belly of ulnar head of the PTM, and in three, posteriorly to both heads of the PTM. When both heads were present, the median nerve was not observed as passing through the muscle belly of the humeral head of PTM. In 14 out of the 100 dissected limbs, the ulnar head of the PTM was not observed; in this situation, the median nerve was positioned posteriorly to the humeral head in 11 limbs, and passed through the humeral head in three. In 17 limbs, the ulnar head of PTM was little developed, with a fibrous band originating from the ulnar coronoid process, associated with a distal muscle component near the union with the humeral head. In four limbs, the ulnar head of the MPR was represented by a fibrous band. In both limbs of one cadaver, a fibrous band was observed between the supinator muscle and the humeral head of the PTM, passing over median nerve. CONCLUSION: The results suggest that these anatomical variations in relationship median nerve and PTM are potential factors for median nerve compression, as they narrow the space through which the median nerve passes.


RESUMO OBJETIVO: Analisar as variações anatômicas do músculo pronador redondo (MPR) e suas implicações na compressão do nervo mediano, que passa entre as cabeças umeral e ulnar do MPR. MÉTODO: Foram dissecados 100 membros superiores de cadáveres adultos pertencentes ao laboratório de anatomia; 46 cadáveres eram do sexo masculino e quatro do feminino. A idade variou entre 28 e 77 anos; 27 eram da etnia branca e 23, não branca. Um estudo piloto que incluiu três cadáveres frescos foi feito, para familiarização dos autores com a anatomia regional. Esses não foram incluídos no estudo. RESULTADOS: Em 86 membros, observou-se a presença das cabeças umeral e ulnar do MPR. Em 72 dos 86 membros, o nervo mediano estava posicionado entre as cabeças umeral e ulnar do MPR; em 11, esse encontrava-se através da massa muscular da cabeça ulnar do MPR e em três, o nervo mediano estava posicionado posteriormente às duas cabeças do MPR. Nos casos em que as duas cabeças do músculo estavam presentes, não se observou o nervo mediano passando através da massa muscular da cabeça umeral do MPR. Em 14 dos 100 membros dissecados, a cabeça ulnar do MPR não estava presente. Nessa situação, o nervo mediano posicionava-se posteriormente à cabeça umeral em 11 membros e através da cabeça umeral em três membros. Em 17 membros, a cabeça ulnar estava muito pouco desenvolvida, com conformação fibrosa em sua origem no processo coronoide da ulna, associada a um componente muscular distal, próximo a sua união com a cabeça umeral. Em quatro membros, a cabeça ulnar do MPR estava representada apenas por uma banda fibrosa. Nos dois membros de um cadáver, observou-se uma expansão fibrosa que saía do músculo supinador para a cabeça umeral do MPR, passando como uma cinta sobre o nervo mediano. CONCLUSÕES: Esses resultados sugerem que as variações anatômicas na relação nervo mediano e MPR representam fatores potenciais para compressão nervosa, por estreitar o espaço no qual passa o nervo mediano.

Ulnar impaction syndrome is one of the common causes of ulnar-sided wrist pain. The pain is usually aggravated by ulnar deviation during a power grip, especially when the forearm is in a pronated position. The most common predisposing factor of ulnar impaction syndrome is ulnar positive variance, which is an increased ulnar length relative to the radius of the radiocarpal joint. However, it can also occur in patients with ulnar neutral or negative variance because ulnar variance can increase during functional activities, including pronation and power gripping. In these patients, the triangular fibrocartilage complex (TFCC) may be thickened. If conservative treatments—lifestyle modification, medication, or wrist splinting—are unsuccessful, surgical treatments, such as wafer procedure or ulnar shortening osteotomy can be considered. The wafer procedure is an effective treatment for ulnar impaction syndrome. It removes the distal 2 to 4 mm of the ulnar head, while preserving the ulnar styloid process from fracturing via a limited open or an arthroscopic approach. The advantages of the wafer procedure are that it does not require bone healing or internal fixation and provides direct access to TFCC. However, it is a technically demanding procedure and is contraindicated in patients with distal radio-ulnar joint (DRUJ) instability, lunotriquetral instability, ulnar minus variance, and with an ulnar positive variance of more than 4 mm. Ulnar shortening osteotomy is the most popular method for the treatment of ulnar impaction syndrome. It can effectively relieve ulnar impaction symptoms and stabilize DRUJ. However, an excessive amount of shortening may increase the peak pressure at DRUJ, which results in DRUJ arthritis. There is also a possibility of delayed union or nonunion in the osteotomy site. To prevent delayed union or nonunion, we should make an effort to decrease the gap in the osteotomy site during surgery. A serial follow-up is also recommended to evaluate the occurrence of arthritis in DRUJ after ulnar shortening.

Concurrent injury of medial malleolus and deltoid ligament is difficult to occur considering the injury mechanism. When the concurrent injury comes about, the deltoid ligament injury could be missed and it may lead to medial ankle instability. There are few reported cases of the concurrent injury and domestic case of concurrent failure of both structures over the medial side has been reported just once; however, the injury mechanism is different from this case. The authors report a case of medial malleolus fracture with deltoid ligament rupture following pronation injury with a review of necessity of repairing deltoid ligament for ankle stability.

PURPOSE: This study was to assess the morphological changes of the pronator quadratus (PQ) muscle using an ultrasonography in the volar locking plate fixation group and in the percutaneous K-wire fixation group for distal radius fracture, and to evaluate the impact on clinical outcomes. MATERIALS AND METHODS: Fifty-four patients who received surgical treatment for distal radius fracture were enrolled in this study. They were divided into two groups according to treatment modality: Group 1 included 34 patients who underwent internal fixation with volar locking plate and Group 2 included 20 patients with percutaneous K-wire fixation. Thickness of the PQ muscle was measured using an ultrasonography at the final follow-up. We evaluated the outcomes using the Mayo wrist score, wrist range of motion, and grip strength at the final follow-up. RESULTS: Compared with the uninjured side, thickness of the PQ muscle showed 31.9% of mean atrophy in Group 1 and 11.4% in Group 2. The atrophy of PQ muscle was severe in Group 1 (p=0.01). However, there was no significant difference in the mean Mayo wrist score between the two groups (83.1±10.9 in Group 1 and 80.2±8.9 in Group 2, p=0.28), except a mild limitation of pronation in Group 1. CONCLUSION: The healed PQ muscle from fracture itself after distal radius fracture revealed a morphological atrophy. Moreover, the volar locking plate resulted in greater atrophy of the PQ muscle, but there was no specific impact on clinical outcomes.
