Toe injuries are common in the emergency department and most of them are treated conservatively. In some circumstances, these injuries can present as a physeal fracture with concomitant soft-tissue injury affecting the nail bed and resulting in a hidden open fracture. To adequately treat these patients, a high index of suspicion is needed to diagnose and treat the open fractures and to prevent complications such as infection, osteomyelitis, malunion and premature physeal arrest.We report a case of a patient that was admitted to the hospital with a Salter-Harris type I fracture of the distal phalanx of the hallux. After confirming the diagnosis, antibiotic treatment was started and the fracture was reduced and fixed.The literature on this entity is sparse and most of the management protocols are based on its hand equivalent—the Seymour fracture, emphasising the low threshold for treating these lesions as an open fracture.

Objective: This study aims to compare the use of halo-gravity traction (HGT) with and without previous anterior release, in terms of curve reduction, for the treatment of pediatric severe spinal deformity. Methods: From 2010 to 2016, all patients treated with HGT prior to instrumentation for scoliosis and kyphoscoliosis were reviewed. They were assessed by deformity etiology, previous anterior release, instrumentation procedure used, traction protocol, major Cobb angle before traction, after the protocol, and after the instrumentation procedure. Twelve patients met these criteria and constituted the sample groups: Group I (n=7) with anterior release and Group II (n=5) without anterior release. Results: The average pre-traction major curve Cobb angles were 114.9o and 108.4º for Group I and II, respectively (P>0.05). After HGT, both groups achieved a significant reduction in curve angle (P0.05). No major HGT related complications were reported. Conclusions: Anterior release prior to HGT did not increase major curve correction after posterior surgery for severe pediatric idiopathic and syndromic scoliosis. HGT is an effective and safe technique, though it frequently presents minor and transitory complications. Level of Evidence III; Retrospective Comparative Study.

The clear decline in the practice of physical activity (PA) in contemporary society has well-documented problematic consequences in public health. It has led to a clear investment of research efforts in the attempt to identify the psychological constructs associated with health behaviors such as PA, in particular, the motivation that leads people to adopt these behaviors. In this context, the objective of the present study is to present a suggestion of a Portuguese version of the Physical Activity and Leisure Motivation Scale (PALMS), denominated PALMS-p. This instrument evaluates the reasons for the practice of PA. The psychometric qualities of the instrument were evaluated in a sample of 234 participants (86 males, 148 females) who practiced different PA in a recreational context. Confirmatory factorial analysis confirmed the factorial robustness of the PALMS-p (&chi, 2/df = 2.010 comparative fit index (CFI) = 0.950, goodness of fit index (GFI) = 0.855, Tucker-Lewis Index (TLI) = 0.939 root-mean-square error of approximation (RMSEA) = 0.021, P(RMSEA &le, 0.05) &lt, 0.001), and the results show that this version presents good internal consistency. The present study corroborates the fidelity and validity of PALMS-p as a motivation measure for the practice of PA in the Portuguese population.

ResumenEl propósito del presente estudio fue descubrir las rela­ciones entre los comportamientos del entrenador percibi­dos por los deportistas durante el entrenamiento y la competición y la cooperación a través de la red baye­siana. Los deportistas masculinos profesionales de varios deportes de equipo (N = 158) completaron la versión portuguesa de la Escala de Liderazgo para el Deporte y el Cuestionario de Cooperación Deportiva para evaluar la cooperación. Se identificaron relaciones entre los comportamientos percibidos del entrenador en entornos de entrenamiento y competición y la tendencia de los atletas a cooperar. En general, los hallazgos apoyan que, en el deporte, los comportamientos del entrenador con­gruentes con las necesidades individuales de los atletas y adaptados a las demandas situacionales pueden promo­ver el comportamiento prosocial. AbstractThe purpose of the present study was to discover the relationships between athletes’ perceived coach behaviors during training and competition, and cooperation via Bayesian network (BN). Professional male atheletes from several team sports (N = 158) completed the Portuguese version of the Leadership Scale for Sport and the Questionário de Cooperação Desportiva to assess cooperation. Relationships were identified between perceived coach behaviors in training and competition environments and with athletes tendency to cooperate. Overall, the findings support that in sports, coaching behaviours congruent with the athletes’ individual needs and adapted to the situational demands may promote prosocial behaviour.

This study attempts to analyze the relationship between two key psychological variables associated with performance in sports - Self-Determined Motivation and Competitive Anxiety - through Bayesian Networks (BN) analysis. We analyzed 674 university students that are athletes from 44 universities that competed at the University Games in Mexico, with an average age of 21 years (SD = 2.07) and with a mean of 8.61 years' (SD = 5.15) experience in sports. Methods: Regarding the data analysis, firstly, classification using the CHAID algorithm was carried out to determine the dependence links between variables; Secondly, a BN was developed to reduce the uncertainty in the relationships between the two key psychological variables. The validation of the BN revealed AUC values ranging from 0.5 to 0.92. Subsequently, various instantiations were performed with hypothetical values applied to the "bottom" variables. Results showed two probability trees that have extrinsic motivation and amotivation at the top, while the anxiety/activation due to worries about performance was at the bottom of the probabilities. The instantiations carried out support the existence of these probabilistic relationships, demonstrating their scarce influence on anxiety about competition generated by the intrinsic motivation, and the complex probabilistic effect of introjected and identified regulation regarding the appearance of anxiety due to worry about performance. info:eu-repo/semantics/publishedVersion

This study is framed on the Information Theory as a constructive criterion to generate probabilistic distributions –through the elaboration of Bayesian Networks- and to reduce the uncertainty in the occurrence and relationship between two key psychological variables associated with the sports’ performance: Self-Determined Motivation and Competitive Anxiety. We analyzed 674 universitary students/athletes who competed in the 2017 Universitary Games (Universiade) in México, from 44 universities, with an average age of 21 years old (SD = 2.07), and with a sportive experience of 8.61 years of average (SD = 5.15). Methods: Regarding the data analysis, first of all a CHAID algorithm was carried out for to know the independence links among variables, and then two Bayesian networks (BN) were elaborated. The validation of the BN revealed AUC values ranging from 0.5 to 0.92. Subsequently, various instantations were carried out with hypothetical values applied to the “bottom” variables. Results showed two probability trees that have Extrinisic Motivation and Amotivation at the top, while the anxiety/activation due to the worry for performance was at the bottom of probabilities. The instantiations carried out support the existence of these probabilistic relationships, demonstrating the little influence on the competition anxiety generated by the intrinsic motivation. In conclusion, the reduction of the uncertainty made up by the restricted BN may aloe to re-introduce Information Theory principles in psychosocial studies, allowing authors to obtain useful probabilities values upon target psychological variables related with sportive performance.

In team sports, athletes' goals may focus on the task (enhancing performance, developing better skills, etc.) or on ego (being better than the others, achieving superiority, etc.). This study investigated the relationships between athletes' goal orientation and their tendency to cooperate with teammates and coaches. 158 professional men ( M age = 24.1 yr., SD = 4.6) who played on various sport teams participated in this study. Goal orientation was measured with the Portuguese version of the Task and Ego Orientation in Sport Questionnaire, and cooperation was measured with the Questionário de Cooperação Desportiva. Cooperation was positively correlated with task orientation, and negatively correlated with ego orientation. Overall, the findings support that in sports, directing the players' focus on task may promote prosocial behavior.

O presente artigo teve por objectivo fazer uma breve revisão do constructo de cooperação desportiva, sendo manifesta a escassez de literatura neste âmbito. De igual modo, pretendeu-se apresentar os instrumentos disponíveis para a sua avaliação, bem como a investigação realizada até à data. Por último, são apresentados alguns estudos que se encontram actualmente em execução e os desafios futuros desta linha de investigação. É de salientar a importância da continuidade da investigação neste âmbito, visto que a cooperação pode ser considerada como um paradigma alternativo válido no estudo e compreensão das dinâmicas das equipas desportivas, que necessita ainda de evidência empírica e experimental.

El objetivo del estudio fue identificar y analizar los beneficios percibidos asociados a la lesión deportiva, en 16 futbolistas profesionales y semiprofesionales que se habían lesionado durante su práctica deportiva. Para la recogida de datos se realizaron entrevistas semiestructuradas, siendo el análisis de contenido efectuado través del software QSR Nvivo 2.0. Los participantes reportaron 31 beneficios percibidos en todo su proceso de lesión, siendo el apoyo social y la educación deportiva los más referidos. Las conclusiones apuntan para la importancia de incluir aspectos positivos para una comprensión más clara y completa del impacto global de las lesiones deportivas. The aim of the study was to identify and analyze the perceived benefits associated with sports injury in 16 professional and semi-professional players who were injured during sports practice. For data collection semi-structured interviews were conducted, content analyses being performed through the QSR Nvivo 2.0 software. 31 participants reported perceived benefits throughout the injury process, with social support and sports education referrals. The findings point to the importance of including positive aspects for a clearer and more complete understanding of the overall impact of sports injuries.

O principal objectivo do presente artigo é apresentar uma sugestão de versão portuguesa do Questionário de Cooperação Desportiva (Garcia-Mas et al., 2006). Este instrumento avalia o grau de cooperação numa situação desportiva, baseada na interacção interpessoal e na busca dos objectivos por parte dos jogadores relativamente aos objectivos da equipa, do treinador e dos seus companheiros. As qualidades psicométricas do instrumento foram avaliadas numa amostra de 127 atletas praticantes de futebol. A análise factorial confirmatória original revelou que os dados obtidos com a versão portuguesa não apresentam uma total sobreposição aos obtidos com a versão espanhola. Assim, adoptando uma estratégia exploratória e tendo em conta a dupla fonte de cooperação (disposicional e situacional), propôs-se uma forma de melhorar a validade de constructo do questionário através de uma nova estrutura factorial e da eliminação de alguns itens. A versão final do QCD-p é composta por 12 itens distribuídos por dois factores disposicionais (Cooperação Condicionada e Cooperação Incondicionada) e um factor situacional (Cooperação com o Treinador). ABSTRACT: The main objective of this study is to present a proposal for the Portuguese version of the “Cuestionário de Cooperación Deportiva” (Garcia-Mas, 2006). This instrument assesses the degree of cooperation in a sportive situation, based on interpersonal interaction and the pursuit of objectives by the players on the objectives of the team, the coach and the companions. The psychometric properties of the instrument were evaluated in a sample of 127 soccer athletes. Confirmatory factor analysis of the original factorial structure revealed that the data in the Portuguese sample did not exactly match the structure obtained in the Spanish version. Thus, adopting an exploratory strategy and taking into account the dual source of cooperation (dispositional and situational), we proposed a way to improve the construct validity of the questionnaire through a new factorial structure and by the deletion of some items. The final version of the QCD-p consists of 12 items distributed by two dispositional factors (Conditional Cooperation and Cooperation Unconditional) and a situational factor (Cooperation with the Coach).

Acute ankle injury is one of the main reasons for observation of patients in the emergency department. Only 15% present with clinically significant fractures, but they are almost always referred for radiography. The Ottawa ankle rules have provided specific directions for carrying out radiography in these situations, allowing a reduction in hospital costs and reducing exposure to ionizing radiation. The aim of the study is to verify that the protocol of the Ottawa rules for evaluating ankle trauma can adapt to a sample of the Portuguese population.This prospective study was done in the Emergency Department of Orthopedics, for a period of 9 months, integrating all patients who presented with complaints in the ankle with less than 48 hours development. All patients underwent radiography of the injured area. Radiographic images were evaluated by the orthopaedic doctor in the emergency department. Patients were reassessed in about 10-15 days after injury by the same observer.We evaluated 123 patients. The average age was 35.2 (range, 7 to 88) years. Sixty had positive criteria for radiological assessment, of which 43 had fracture; none of the patients with negative criteria had fratures. Sensitivity of Ottawa ankle rules for detecting fractures was 100%.The implementation of the Ottawa ankle rules appears to have potential to reduce the number of radiographs for the assessment of these patients by about 51%. The results of this study demonstrate no false negatives and are consistent with the results of other similar studies which sensitizes us to implement these criteria in our emergency services.

As deformidades axiais dos membros inferiores constituem um dos principais motivos de consulta na area de Ortopedia Infantil. Esta situacao deve-se, por um lado, ao facto de haver uma grande percentagem de criancas (cerca de 20%) que apresentam uma deformidade fisiologica durante o desenvolvimento e, por outro, a «tradicao» existente, segundo a qual estes desvios necessitam de um tratamento, usualmente por calcado ortopedico. Torna-se, por isso, imperioso destrincar o fisiologico do patologico, diferenciar as diferentes etiologias e corrigi-las precocemente medicamente e, ainda, determinar quando uma deformidade e passivel de correccao espontânea ou quando exige uma terapeutica cirurgica.
