Use of Smartphones as a Risk Factor for the Development of Morbidities in the Wrist and Fingers.

Objective To investigate the long-term use of smartphones as a risk factor for the development of morbidities in the wrist and fingers. Methods The present is a descriptive, exploratory study with a quantitative approach based on injury prevalence among one hundred smartphone users of a private university in the state of Pernambuco, Northeastern Brazil. We applied a semi-structured questionnaire and the Boston Carpal Tunnel Questionnaire (BCTQ), as well as the Visual Analog Scale (VAS) and the Finkelstein, Phalen, reverse Phalen, and Tinel signal tests on the wrist. Results The average of the sample was of 22.73 years, with a prevalence of single, right-handed female participants. Most of them had been using smartphones for 5 to 10 years, and 85% reported discomfort in the wrist and fingers while using the device, with numbness as the most prevalent symptom. Most clinical tests were negative, and the Finklestein test showed greater positivity. The BCTQ is composed of a symptom severity scale (S scale) and a functional status scale (F scale): the overall score on the S scale was of 1.61, indicating mild to moderate symptoms, and the F scale revealed that the symptoms did not affect functionality. Conclusion There was a significant correlation between the length of use of smartphones and discomfort in the wrist and fingers; as such, smartphones are a risk factor for the development of morbidities.

Resumo Objetivo Investigar o uso de smartphones em longo prazo como fator de risco para o desenvolvimento de morbidades no nível do punho e dos dedos. Métodos Realizou-se um estudo descritivo, exploratório, de abordagem quantitativa, para a obtenção de medidas de prevalência com cem acadêmicos usuários de smartphones de uma faculdade privada localizada no sertão de Pernambuco. Foram aplicados um questionário semiestruturado e o Questionário de Síndrome doTúnel do Carpo de Boston (Boston Carpal Tunnel Questionnaire, BCTQ, na sigla em inglês), além da Escala Visual Analógica (EVA) e dos testes de Finkesltein, Phalen, Phalen reverso, e sinal de Tinel no punho. Resultados A idade média da amostra foi de 22,73 anos, com prevalência de solteiros, de destros, e do sexo feminino. O tempo de uso do smartphone indicado pela maioria dos participantes era entre 5 e 10 anos, e 85% da amostra relatou já ter sentido desconforto no punho e nos dedos durante o uso do aparelho, sendo a dormência o sintoma mais prevalente. Com relação aos testes clínicos, houve prevalência de resultados negativos, e o de Finklestein apresentou maior positividade. Quanto ao BCTQ, dividido em duas escalas, uma de gravidade dos sintomas (escala G) e uma de estado funcional (escala F), a média geral das pontuações foi de 1,61 na escala G, o que indica sintomas de leve a moderados, já a escala F revelou que os sintomas não afetavam a funcionalidade. Conclusão Foi possível observar uma correlação significativa entre o tempo de uso dos smartphones e a presença de desconforto no punho e nos dedos, o que indica que se trata de um fator de risco para o desenvolvimento de morbidades.

Disability of Arm, Shoulder and Hand and Michigan Hand Outcomes Questionnaires: Exploring Responsiveness and Diagnostic Performance in a Sample of Outpatients with and without Hand and Wrist Complaints.

Objective The present study aimed to verify whether, in an adult population with nontraumatic complaints in the upper limbs, (1) the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and the Michigan Hand Outcomes Questionnaire (MHQ) are susceptible to a "ceiling effect" when compared with a sample of healthy subjects; and (2) to determine cutoff points for diagnostic performance and the intercorrelation for DASH and MHQ in both samples. Methods This was a prospective, comparative, nonrandomized study. In total, 150 subjects were included, with 75 in the case group (with disease) and 75 in the control group (without disease). This was a sample of patients recently admitted to a hand surgery outpatient clinic. Controls were matched to clinical cases according to inclusion. The ceiling effect was determined by a maximum response rate (> 15%); receiver operating characteristic (ROC) curves determined cutoff points for sickness definition, and DASH and MHQ sensitivity and specificity. Statistical significance was set at p < 0.05. Results The DASH and MHQ questionnaires had no ceiling effect for the case group. In this group, 18 (24%) patients had the maximum DASH score, but none (0%) had the maximum MHQ score. For the control group, 1 (1.33%) subject had the maximum DASH score, but none scored for MHQ. For case determination, DASH scores of 7.1 had 80% sensitivity and 60.3% specificity, whereas MHQ scores of 76.9 had 56.2% sensitivity and 97.3% specificity. Conclusion The DASH and MHQ questionnaires are reliable tools to measure the impact of hand and wrist morbidities on daily activities, and they are not susceptible to ceiling effects. The DASH questionnaire is more sensitive for patient identification, whereas the MHQ is more specific. As such, the MHQ seems more appropriate when a more specific functional increase is expected.

Resumo Objetivo Verificar se, em uma população adulta com queixa não traumática dos membros superiores, (1) os questionários Disability of the Arm, Shoulder and Hand (DASH, na sigla em inglês) e Michigan Hand Questionnaire (MHQ, na sigla em inglês) estão suscetíveis ao "efeito de teto", comparando com amostra de não-doentes; (2) determinar pontos de corte de performance diagnóstica e correlação interquestionários para DASH e MHQ em ambas as amostras. Método Estudo prospectivo, comparativo e não randomizado. Incluímos 150 pacientes, 75 no grupo caso (com doença) e 75 no grupo controle (sem doença). Trata-se de amostra de pacientes recém-admitidos em ambulatório de cirurgia da mão. Os controles foram pareados de forma balanceada de acordo com a inclusão dos casos. Determinamos a presença de efeito de teto por meio da taxa de respostas máximas (> 15%) e associamos curvas receiver operating characteristic (ROC, na sigla em inglês) para a determinação de pontos de corte para a determinação de doentes, associados a medidas de sensibilidade e especificidade. Consideramos p < 0.05 para significância estatística. Resultados Os questionários DASH e MHQ não demonstraram o efeito de teto para o grupo com doença. A porcentagem de pacientes do grupo caso com nota máxima foi de n = 18 (24%) no DASH e de 0% no MHQ. Para o grupo sem doença, 1 (1,33%) dos participantes pontuou com nota máxima para DASH, enquanto nenhum pontuou para o MHQ. Na determinação de casos, escores de DASH de 7,1 apresentam sensibilidade de 80% e especificidade de 60,3%. Para o MHQ, um escore de 76,9 apresenta sensibilidade de 56,2% e especificidade de 97,3%. Conclusão Os questionários DASH e MHQ são ferramentas confiáveis na mensuração do impacto das morbidades das mãos e dos punhos nas atividades diárias dos pacientes e não são suscetíveis a efeito de teto. O questionário DASH é mais sensível para a identificação de doentes, enquanto o MHQ é mais específico. Em situações nas quais se espera um incremento funcional mais discreto (ou mais específico), o MHQ parece mais adequado.

The reconstruction of the traumatic hand with substance loss, involves a reconstruction with surgical procedures, which provide an adequate covering of skin and soft tissues with the use of fascio cutaneous Flaps. In the present case, the use of Mc Gregor's Inguinal Flap is a technique that allows to achieve significant results to restore the functionality of the affected area, when performing an immediate and timely maintenance treatment, the subsequent sequelae are significantly reduced. Speaking of history Mc Gregor and Jackson in 1972 described the inguinal flap, vascularized by the superficial iliac circumflex artery branch of the femoral artery, being the only one consecrated by the use (not only used as a pedicle flap, but also as a free flap) for coverage of head, neck, trunk and limb conditions, allowing an acceptable functional and aesthetic result. Present work reports the case of a 6 years and 7 months old male patient, with history of left-hand trauma due to dynamite explosion, with substance loss and traumatic amputation of the 1st. and 2nd. Fingers.

INTRODUCCIÓN: Los traumas de mano tienen una alta incidencia alrededor del mundo y representan alrededor del 30% de todos los accidentes y visitas a servicios de urgencias, siendo las lesiones de la punta del dedo un subtipo común de trauma de mano. El manejo inicial y la elección del tratamiento adecuado son importantes, el principal objetivo es la cobertura de tejidos para así evitar amputaciones innecesarias, prevenir complicaciones y pérdida de funcionalidad. CASO CLÍNICO: Paciente masculino de 32 años que sufrió trauma por aplastamiento en mano derecha que produce herida con pérdida de tejido en falanges distales de segundo y tercer dedo y amputación traumática parcial de falange distal del segundo dedo. EVOLUCIÓN: Se realizó técnica quirúrgica de colgajo adipofascial vascularizado homodigital reverso en segundo dedo y manejo conservador de fractura, sin complicaciones. Se llevó un control semanal por 2 meses con resultados funcionales, biológicos y estéticos favorables. El tercer dedo se trató con limpieza quirúrgica y colocación de vendaje suboclusivo con evolución favorable. CONCLUSIÓN: El colgajo adipofascial dorsal homodigital reverso tiene varias ventajas sobre otros tipos de colgajos más convencionales; es una técnica simple, segura y confiable, con buenos resultados postquirúrgicos en cuando a funcionalidad, estética y recuperación, requiere de un solo tiempo quirúrgico y brinda la cobertura necesaria de los tejidos expuestos tanto óseos como blandos, con mínima morbilidad del sitio donante.(au)

BACKGROUND: Hand trauma has a high incidence worldwide, it accounts nearly 30% of all trauma and medical visits to emergency rooms, fingertip injuries are the most common among hand trauma. The initial management and the proper choice of treatment are important, the main objective is to achieve adequate tissue coverage, in order to avoid unnecessary amputation, prevent complications and functionality loss. CASE REPORT: A 32-year-old male patient presented with crush trauma on right hand resulting in injuries with tissue loss on the fingertips of the second and third finger and traumatic partial amputation of the distal phalanx of the second finger. EVOLUTION: Surgical technique of homodigital vascularized adipofascial reverse flap was performed in second finger and the fracture was managed conservatively, without complications. A weekly follow up was carried out for 2 months with favorable functional, biological and aesthetic results. The third finger was treated with surgical irrigation and debridement and placement of a sub-occlusive bandage, with favorable outcome. CONCLUSION: Homodigital adipofascial reverse dorsal flap has advantages over other types of conventional flaps; it is a simpler, safe and reliable technique, with good postsurgical outcomes in terms of functionality, aesthetics and recovery, needing only one intervention and offering the appropriate coverage to exposed bone and soft tissue, with minimal repercussions on the donor site.(au)

Reconstrução tardia na mão traumatizada com perda de múltiplos dedos / Late reconstruction of a traumatized hand with loss of multiple fingers

As lesões mutilantes de mão são um desafio para o cirurgião de mão e o paciente. O cirurgião deve tomar decisões desde o debridamento inicial, escolhendo quais dedos e articulações serão preservadas e uso apropriado das partes a serem retiradas. A reconstrução tardia é a segunda parte dessa difícil tarefa. Dificuldade que se atribui à particularidade de cada lesão, do grande número de possibilidades de tratamento e seus diversos níveis de complexidade que devem ser adequados à necessidade e motivação pessoal de cada paciente. Este relato de caso apresenta uma reconstrução tardia de mão com perda de indicador e dedo médio com transplante de articulação metacarpofalângica de indicador para função de interfalangeana proximal de dedo médio.

Mutilating hand injuries are a challenge to both the hand surgeon and the patient. The surgeon must make decisions ranging from the initial debridement to which fingers and joints will be preserved and the appropriate use of the parts to be removed. Late reconstruction constitutes the second part of this difficult task. The difficulty attributed to the characteristics of each lesion, the large number of treatment possibilities, and the different levels of complexity must be adapted to the personal needs and motivation of each patient. This case report describes a late hand reconstruction with index and middle finger loss, using metacarpophalangeal joint transplantation of the index finger to gain the proximal interphalangeal function of the middle finger.

Transtriquetral perihamate fracture-dislocation: case report.

The wrist is a region that is very vulnerable to injuries of the extremities. Among these injuries, fractures of the pyramidal bone (or triquetrum) in association with dislocation of the hamate and carpal instability are uncommon. They are generally correlated with high-energy trauma and may be associated with neurovascular deficits, muscle-tendon disorders, skin lesions or injuries to other carpal bones. Thus, in this report, one of these rare cases of transtriquetral perihamate fracture-dislocation with carpal instability is presented, diagnosed by means of radiography on the right wrist of the patient who presented pain, edema and limitation of flexion-extension of the carpus after trauma to the region. The stages of attending to the case are described, from the initial consultation to the surgical treatment and physiotherapy, which culminated in restoration of the strength and range of motion of the wrist.

O punho é uma região muito vulnerável a traumas de extremidade. Entre tais lesões, as fraturas do piramidal (ou triquetrum), associadas à luxação do hamato e à instabilidade carpal, são pouco frequentes. Geralmente relacionadas a traumatismos de alta energia, podem estar associadas a déficit neurovascular, miotendíneo, lesões de pele ou em outros ossos do carpo. Assim, neste relato, apresenta-se um desses casos raros de fratura-luxação transtriquetral peri-hamato com instabilidade carpal, diagnosticadas por radiografias do punho direito de um paciente que apresentava dor, edema e limitação da flexoextensão do carpo após trauma na região. As etapas do atendimento foram descritas desde a consulta inicial até o tratamento cirúrgico e a fisioterapia, que culminaram com a restauração da força e da amplitude de movimento do punho.

Reconstruções complexas de membros superiores e inferiores com retalhos de fluxo reverso: uma série de 32 casos / Complex reconstruction of the upper and lower limbs by using reverse-flow flaps: a series of 32 cases

Introdução: A reconstrução de partes moles após perdas de substância do terço distal dos membros superiores e inferiores, principalmente quando associada à exposição de estruturas nobres (osso, tendão, nervos ou vasos sanguíneos), continua a desafiar a cirurgia plástica. Os retalhos fasciocutâneos de fluxo reverso são uma eficiente opção cirúrgica na cobertura de lesões pequenas e médias nesta localização. Método: Foi realizado um estudo clínico retrospectivo, no período de janeiro de 2013 a dezembro de 2014, de uma série de 32 casos de traumas complexos em membros superiores e inferiores. Resultados: Foram realizados 24 retalhos de fluxo reverso nos membros inferiores e 8 nos membros superiores, observando-se uma cobertura eficaz dos defeitos. Conclusão: Os retalhos de fluxo reverso são confiáveis e apresentam arcos de rotação que permitem a cobertura de lesões diversas no terço distal de membros superiores e inferiores.

Introduction: Reconstruction of the soft tissues after loss of substance in the distal third of the upper and lower limbs, in particular when associated with the exposure of noble structures (bone, tendon, nerves, or blood vessels), remains a challenge in plastic surgery. Fasciocutaneous reverse flow flaps are an efficient surgical option for covering small and medium lesions in this location. Method: A retrospective clinical study was performed on a series of 32 cases of complex trauma of the upper and lower limbs treated between January 2013 and December 2014. Results: A total of 24 reverse-flow flaps were performed in the lower limbs and eight in the upper limbs, resulting in efficient coverage of the defects. Conclusion: Reverse-flow flaps are reliable and present rotation arcs that allow coverage of a variety of lesions in the distal third of the upper and lower limbs.

Fatores associados ao retorno ao trabalho após um trauma de mão: uma abordagem qualiquantitativa / Factors associated with return to work following a hand injury: a qualitative/quantitative approach

OBJETIVOS: Descrever os trabalhadores que retornaram ao trabalho após um trauma de mão e analisar os fatores que se associaram a esse desfecho após três anos da alta da reabilitação. MÉTODOS: Foi realizado um estudo observacional, de corte transversal, com triangulação dos métodos quantitativo e qualitativo. A análise quantitativa utilizou um banco de dados com informações sociodemográficas, funcionais e clínicas referentes a 35 indivíduos, classificados em dois grupos (retornou/não retornou ao trabalho). Foi conduzida análise multivariada, utilizando o algoritmo CART (Classification and Regression Tree) para avaliar o valor preditivo de quatro modelos, identificando trabalhadores que retornaram ou não ao trabalho. A partir dos resultados da análise estatística, foi elaborado um roteiro semiestruturado para as entrevistas que foram realizadas com sete trabalhadores selecionados aleatoriamente da amostra. RESULTADOS: Dos 35 trabalhadores que participaram deste estudo, 30 retornaram e cinco não retornaram ao trabalho. A maioria era do sexo masculino, com média de idade de 37 anos, casada e de baixa escolaridade. As variáveis com maior força preditiva foram força de preensão, escores do desempenho ocupacional, categoria ocupacional e idade. O estudo qualitativo confirmou a natureza multifatorial do retorno ao trabalho, demonstrando que a presença de um profissional para acompanhar o processo, alguns ajustes no posto e no horário de trabalho, possibilitando uma continuidade do tratamento, e o auxílio-acidente podem contribuir para o sucesso do retorno. CONCLUSÕES: Este estudo evidenciou a complexidade do retorno ao trabalho de trabalhadores com lesão de mão, apontando vários fatores associados a esse desfecho e a importância de uma avaliação individualizada, centrada no trabalhador

OBJECTIVES: To describe workers who returned to work after a hand injury and to analyze the factors associated with this outcome three years after discharge from rehabilitation. METHODS: An observational, cross-sectional study was carried out with triangulation of quantitative and qualitative methods. The quantitative analysis used a database with sociodemographic, functional and clinical information on 35 individuals who were classified into two groups (return/no return to work). Multivariate analysis was conducted using the CART (Classification and Regression Tree) algorithm to assess the predictive value of four models, thereby identifying workers who had returned or not returned to work. Using the results from the statistical analysis, a semi-structured form was prepared for interviews, which were conducted with seven workers randomly selected from the sample. RESULTS: Out of the 35 workers who participated in this study, 30 returned and five did not return to work. The majority were male, married and of low educational level, and the mean age was 37 years. The variables with the greatest predictive power were grip strength, occupational performance scores, occupational category and age. The qualitative analysis confirmed the multifactorial nature of the return to work and demonstrated that the presence of a professional to follow-up the process, adjustments to the workstation and working hours (to enable treatment continuity) and also accident benefits may contribute to a successful return. CONCLUSIONS: This study showed the complexity of the return to work by workers with hand injuries, highlighting a number of factors associated with this outcome and the importance of individualized assessment centered on the worker.

Cobertura fasciocutánea en trauma de mano con colgajo inguinal: presentación de un caso: Hospital Luís Vernaza, Guayaquil / Fasciocutaneous coating in hand injury with inguinal flan, case presentation: Luis Vernaza Hospital of Guayaquil

Las quemaduras son injurias frecuentes que ocasiona gran número de secuelas. La mayoría de los individuos que las padecen, no sólo se quejan de problemas físicos sino también psicológicos. La verdadera reconstrucción de la mano comienza con los procedimientos quirúrgicos que proporcionan una cubierta adecuada de piel y tejidos blandos. Históricamente los colgajos a distancia fue el primero utilizado en caso de grandes pérdidas de sustancia de la mano (colgajo abdominal, colgajo braquial e infraclavicular)3. La segunda generación de estos colgajos a distancia está representada por aquellos con pedículo axial. Shaw y Payne en 1946 describió el colgajo abdominal vascularizado por la arteria epigástrica superficial. Finalmente, McGregor y Jackson propusieron en 1972 un colgajo inguinal vascularizado por la arteria ilíaca superficial, siendo el único consagrado por el uso, no solo utilizándose como colgajo pediculado, sino como colgajo libre para los problemas de la cabeza, cuello, tronco y extremidades14,17. Al realizar un tratamiento inmediato y de mantenimiento oportuno, se disminuye de forma notable el número de problemas posteriores. Sin embargo, en la actualidad aún continúa apareciendo deformidades debido a un incorrecto tratamiento durante la fase inicial. El presente trabajo reporta el caso de un paciente de 43 años con antecedente de trauma de mano por quemadura eléctrica en región palmar derecha y exposición tendinosa más lesión de tendones flexores superficiales y profundos de 2do. 4to. y 5to. dedos.

Burns are common injuries that cause numerous after-effects. Most people suffering them complains not only of physical problems but also of psychological ones. The real rebuilding of the hand starts with the surgical procedures that supply an appropriate coating of skin and soft tissues. Historically, the remote flaps were the first used in case of large substance loss in the hand (abdominal flap, brachial flap, and infraclavicular flap). The second generation of these remote flaps is represented by those with axial pedicle. Shawn and Payne in 1946 described the inguinal flap irrigated by the superficial epigastric artery. Finally, McGregor and Jackson suggested in 1972 an inguinal flap irrigated by the superficial iliac artery and it is the only one confirmed by use, not only using it as a pediculate flap, but as a free flap for injuries in head, neck, trunk and limbs. Giving immediate treatment and timely maintenance the number of further problems is reduced in a noticeable way. Nevertheless, currently, deformities are still showing up because wrong treatments in initial stage. This paper reports the case of a 43 years old patient with a hand injury history by electric shock in the right palm and tendon exposure plus injury in his superficial an deep flex tendons of 2nd, 4th, and 5th fingers.
