Objective : To evaluate the results of displaced radial neck fractures in children trated surgically with flexible titanium intramedullary nails. Method : This is a retrospective study of five cases of radial neck fractures with displacement greater than 30° fixed with flexible intramedullary nails. Patients were evaluated regarding functional outcome through range of motion and the Mayo Elbow Performance Score (MEPS), as well as radiographic exams. Results : Five patients, with a mean age of 8.4 years were assessed, during a mean post-operative follow up of 12.2 months. Open reduction was necessary in three cases with major displacement. At the end of the follow up, 80% of the patients had excellent results, 20% good results, and all fractures healed. As complications we observed: heterotopic ossification, superficial infection and radial head necrosis. Conclusions : In spite of the small sample, our results with flexible titanium intramedullary nails were similar to the current literature, with good functional outcomes. Level of Evidence III, Retrospective Study.

OBJETIVO: Avaliar se a concentração sérica de vitamina D está associada ao status de marcha e à mortalidade em pacientes com fratura de fêmur proximal seis meses após a fratura.MÉTODOS: Avaliados prospectivamente pacientes consecutivos com fratura de fêmur proximal, com idade ≥ 65 anos, internados na enfermaria de ortopedia e traumatologia do serviço, entre janeiro a dezembro de 2011. Foram feitas análises clínica, radiológica, epidemiológica e laboratorial, incluindo vitamina D. Foram submetidos à cirurgia e acompanhados ambulatorialmente em retornos 15, 30, 60 e 180 dias após a alta, quando foram avaliados os desfechos de marcha e mortalidade.RESULTADOS: Avaliados 88 pacientes. Dois foram excluídos por causa de fratura patológica. Oitenta e seis pacientes com idade média de 80,2 ± 7,3 anos foram estudados. Em relação à vitamina D sérica a média foi de 27,8 ± 14,5 ng/mL e 33,7% dos pacientes apresentavam deficiência dessa vitamina. Em relação à marcha, a análise de regressão logística uni e multivariada mostrou que a deficiência de vitamina D não esteve associada a sua recuperação, mesmo após ajuste por gênero, idade e tipo de fratura (OR 1,463; 95% IC 0,524-4,088; p = 0,469). Considerando a mortalidade, a análise de regressão de Cox mostrou que a deficiência de vitamina D também não esteve relacionada à sua ocorrência em seis meses, mesmo na análise multivariada (HR 0,627; 95% IC 0,180-2,191; p = 0,465).CONCLUSÃO: A concentração de vitamina D sérica não esteve relacionada ao status de marcha e/ou à mortalidade em paciente com fratura de fêmur proximal seis meses depois dela.

OBJECTIVE: To assess whether serum vitamin D concentration is associated with gait status and mortality among patients with fractures of the proximal femur, six months after suffering the fracture.METHODS: Consecutive patients aged ≥65 years with fractures of the proximal femur, who were admitted to the orthopedics and traumatology ward of our service between January and December 2011, were prospectively evaluated. Clinical, radiological, epidemiological and laboratory analyses were performed, including vitamin D. The patients underwent surgery and were followed up as outpatients, with return visits 15, 30, 60 and 180 days after discharge, at which the outcomes of gait and mortality were evaluated.RESULTS: Eighty-eight patients were evaluated. Two of them were excluded because they presented oncological fractures. Thus, 86 patients of mean age 80.2 ± 7.3 years were studied. In relation to serum vitamin D, the mean was 27.8 ± 14.5 ng/mL, and 33.7% of the patients presented deficiency of this vitamin. In relation to gait, univariate and multivariate logistic regression showed that vitamin D deficiency was not associated with gait recovery, even after adjustment for gender, age and type of fracture (OR: 1.463; 95% CI: 0.524-4.088; p = 0.469). Regarding mortality, Cox regression analysis showed that vitamin D deficiency was not related to its occurrence within six months, even in multivariate analysis (HR: 0.627; 95% CI: 0.180-2.191; p = 0.465).CONCLUSION: Serum vitamin D concentration was not related to gait status and/or mortality among patients with fractures of the proximal femur, six months after suffering the fracture.

OBJETIVO: Avaliar a sensibilidade do aparelho photoscreener na detecção de alterações oculares em crianças informantes, comparando os dados à acuidade visual obtida pela tabela E de Snellen. MÉTODOS: Foram avaliadas 500 crianças de idades entre 5 e 12 anos, de escola do município de Botucatu, estado de São Paulo. As crianças foram submetidas ao teste de acuidade visual pela tabela E de Snellen e foram fotografadas utilizando-se o aparelho photoscreenerTM system model MTI-PS100, seguindo-se a análise das fotos obtidas. RESULTADOS: Houve concordância negativa (criança com boa acuidade visual e teste negativo com o photoscreener) em 81,0%; concordância positiva (acuidade visual alterada e teste positivo) em 7,6% e não houve concordância de resultados em 11,0% dos casos. CONCLUSÃO: A avaliação comparativa entre o método da acuidade visual pela tabela E de Snellen e o photocreener para detecção de problemas visuais mostrou alta concordância. Os autores sugerem entretanto, a triagem usando tabelas de acuidade visual quando se trata de crianças informantes, devido aos custos com o aparelho.

PURPOSE: To evaluate the sensitivity of the photoscreener equipment to detect ocular changes in informative children comparing with the data obtained by the E Snellen´s table. METHODS: We evaluated 500 children between 5 and 12 years old, from a school of Botucatu city, São Paulo state. The children were submitted to a visual acuity test using the Snellen´s E Table and were photographed with the photoscreenerTM system model MTI-PS100, following the photos' analyze. RESULTS: There were negative agreement (children with a good visual acuity and a negative test with the Photoscreener) in 81.0%; positive agreement (children without a good visual acuity and a positive test) in 7.6% and there was no agreement of the results in 11.0% (9) of the cases. CONCLUSION: The comparative analysis between the visual acuity test using the Snellen's E table and the photoscreener to detect visual problems showed high agreement. However, the authors suggest that the visual screening should be made by using the visual acuity Tables when the children examined are in informer age, because of the costs of the equipment.
