Estudo retrospectivo de radiografias de cotovelo de crianças atendidas no Hospital das Clínicas para avaliação dos centros de ossificação secundários / Retrospective study of elbow radiographs of children in the Hospital das Clínicas for ossification centers evaluation

Miyazaki, Cesar Satoshi 17 June 2016 (has links)
Introdução: O conhecimento do surgimento gradual dos núcleos de ossificação secundários do cotovelo é importante na avaliação de trauma em crianças, possibilitando o diagnóstico de fraturas e luxações ou mesmo descartando estas patologias, fatores estes que influenciam diretamente na decisão do tratamento, evolução e prognóstico da lesão. É amplamente difundido na literatura mundial que a ordem cronológica de aparecimento desses núcleos seja: capítulo do úmero, cabeça do rádio, epicôndilo interno ou medial, tróclea do úmero, olécrano e epicôndilo externo ou lateral, além da idade de seus surgimentos, porém estas informações apresentam certas divergências em diferentes estudos e publicações e sofrem alterações conforme a população estudada. Objetivos: Avaliar a ordem de surgimento e de fusão dos núcleos de ossificação secundários do cotovelo, correlacionar com a idade e gênero e descrever suas características na nossa população. Materiais e Métodos: Foram avaliados pacientes de 0 a 18 anos de idade já submetidos por indicação clínica ao exame de radiografia simples do cotovelo nas Unidade Campus e Unidade de Emergência do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (FMRP-USP) no período de setembro de 2010 a setembro de 2015. Foram realizadas duas avaliações por 2 radiologistas de forma independente e às cegas com um intervalo de tempo de dois meses entre as leituras. Resultados: Em nosso estudo, observou-se uma tendência do núcleo de ossificação do olécrano surgir antes da tróclea, porém sem significância estatística. Nos pacientes do sexo feminino, notou-se que os núcleos surgem e se unem mais precocemente do que nos pacientes do sexo masculino, com exceção do capítulo e do rádio, além disso os núcleos do rádio e do epicôndilo medial apresentaram uma tendência de surgirem em idades semelhantes. Conclusão: Os núcleos de ossificação do cotovelo surgem e se fundem antes no sexo feminino. Além disso, há tendência do núcleo de ossificação do olécrano surgir antes da tróclea em ambos os sexos, bem como o do rádio e do epicôndilo medial aparecerem em idades semelhante no sexo feminino. / Introduction: The knowledge of the gradual appearance of secondary ossification of the elbow is important in the evaluation of trauma in children, allowing the diagnosis of fractures and dislocations or even discarding these conditions. These factors directly influence the treatment decision, evolution and prognosis of lesions. It is widespread in the literature that these nuclei appear in chronological order which is: the humerus capitellum, radial head, internal or medial epicondyle of the humerus trochlea, olecranon and outer or lateral epicondyle, as well as the age of their appearances. However, these information changes as diverse populations are studied in different studies and publications. Objectives: To evaluate the order of appearance and fusion of secondary ossification of the elbow cores correlate with age and gender and describe their characteristics in the studied population. Materials and Methods: We evaluated patients 0-18 years of age who have undergone a clinical indication to take simple elbow radiography in Campus Unit and Emergency Unit of the Hospital das Clínicas de Ribeirão Preto, University of Sao Paulo ( FMRP-USP) from September 2010 to September 2015. Two independent and blind evaluations were performed by two radiologists with a two-month time interval. Results: In our study, we observed a tendency of ossification nucleus of the olecranon to appear before the trochlea, but without statistical significance. In female patients, it was noticed that the nuclei arise and fuse earlier than in male patients, except for the capitellum and radio. Also, the nuclei of radio and medial epicondyle tended to arise in similar ages Conclusion: The elbow ossification centers arise and fuse before in females than in males. In addition, there is a tendency of ossification nucleus of the olecranon to appear before the trochlea in both sexes, as well as the radio and the medial epicondyle nuclei appear at similar ages in females.

The Effect of the Elbow Pipe to the Guided Waves

Chang, Tzung-wei 31 August 2007 (has links)
In this study, the most part is acquainted with the effect of elbow pipe to the guided wave. Elbow pipes were most seen feature in work environment. It was difficult for inspection that the anti-symmetric of signal increased when it passed the elbow pipe by happening mode conversion. The study content includes the using modal solution of the finite element method to solve the dispersion curve of four different bend radius of elbow pipe, they were : 1.0 m, 0.6 m, 0.4 m and 0.2 m. Therefore, by using simulation of wave propagation and experiment to verify dispersion curve of bend pipe were accuracy. This study reveals that, the dispersion curve of elbow pipe is similar to that of straight pipe, and T(0,1) mode in the elbow pipe is most similar with it in straight pipe. Thus, the dispersion curve in elbow pipe and straight pipe were similar, but the effect of geometry of elbow pipe will make the symmetrical incident signal time delay and wave front will distortion, and then it will cause mode conversion. According to the experiment of this study, although the signal of feature behind the elbow pipe caused by mode conversion will make anti-symmetry of reflection signal increase, it still won¡¦t make shift between reflection signal location and real feature location. It is very difficult and complex for inspecting the particular geometry pipe. If we can use the modal analysis of finite element method to solve the dispersion curve of particular geometry pipe, the inspection can be improve.

The relative effectiveness of dry needling the extensor muscles of the forearm as an adjunct to cross friction massage in the treatment of lateral epicondylitis

Marquis, Janay January 2002 (has links)
Thesis (M.Tech.: Chiropractic)- Dept. of Chiropractic, Durban Institute of Technology, 2002. 113 leaves / Lateral epicondylitis is the most common cause of chronic lateral elbow pain in adults (Bowen et al. 2001:642). No uniform treatment regime is available for lateral epicondylitis, although most authors do agree that treatment should begin with a conservative approach before progressing to more complex and invasive therapies (Kamien 1990:174). The purpose of this study was to investigate the relative effectiveness of dry needling myofascial trigger points of the forearm extensor muscles as an adjunct to cross friction massage, in the treatment of lateral epicondylitis.

The relative effectiveness of cross friction and Mill's manipulation as compared to cross friction alone in the treatment of lateral epicondylitis (tennis elbow)

Shaik, Junaid January 2000 (has links)
Thesis submitted in partial compliance with the requirements for a Master's Degree in Technology: Chiropractic at Technikon Natal, 2000. / The purpose of this study was to determine the relative effectiveness of cross friction combined with Mill's manipulation compared to cross friction alone in the treatment of lateral epicondylitis. This was a prospective, controlled study. The study involved thirty subjects, fifteen randomly allocated into two groups. These patients were selected from the general population by purposive sampling methods. Group 1 received cross friction and Mill's manipulation while Group 2 received cross friction only. Each subject was treated 6 times over a three-week period. Patients were required to return for a one-month follow-up from the date of their last consultation. / M
