Backstage pass

A “Backstage Pass”, l’exposició de fi de curs creada pels alumnes d’aquest any, tenim el privilegi d’entrar en els processos creatius d’aquests 25 joves il·lustradors emergents. Ells comparteixen els seus treballs i inquietuds amb gran varietat d’estils visuals i conceptuals, tot just, al principi de les seves carreres. Estic segur que molts d’aquests nous talents seran els il·lustradors destacats del dia de demà. Gaudim doncs d’aquesta mirada íntima i generosa.En “Backstage Pass”, la exposición de fin de curso, creada por los alumnos de este año, tenemos el privilegio de entrar en los procesos creativos de estos 25 jóvenes ilustradores emergentes.

They share their work & talents through a wide variety of visual and conceptual styles, in this moment, at the beginning of their careers. I'm sure many of these new talents will be tomorrow’s outstanding illustrators. Let's enjoy this intimate and generous look into their current work

Eriosema Elegans (leguminosae, Papilionoideae): A New Species From The Highlands Of Goias State, Brazil

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)During a taxonomic study of Eriosema in Brazil, a new species was discovered from the Chapada dos Veadeiros National Park, Goias State. Eriosema elegans is herein described and illustrated and its morphological affinities with related species discussed. The geographical distribution, conservation status, and information about flowering and fruiting are provided. Also, a study of secretory structures of leaflets of the new species and the morphologically related species E. glabrum was carried out.29618187CNPq [457911/2013-1, 141628/2016-2, 140598/2015-4]Coordination of Improvement of Higher Education Personnel (CAPES)FAPESP [2015/13386-0]Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Avaliação do ângulo de inclinação tibial e altura patelar após osteotomia tibial de abertura medial

OBJETIVO: Mensurar a variação do ângulo de inclinação tibial posterior e da altura patelar em pacientes submetidos à osteotomia valgizante tibial proximal com técnica de cunha de abertura medial. MÉTODOS: Foram analisadas radiografias panorâmicas de membros inferiores em anteroposterior e perfil do joelho pré e pós-operatórias de 46 pacientes com artrose unicompartimental do joelho, em que se realizou osteotomia tibial. RESULTADOS: Em 23 casos, utilizou-se fixador externo para confecção de cunha de abertura medial gradual e nos outros 23, foi utilizada placa bloqueada com batente como método de fixação. Foram excluídos deste estudo aqueles pacientes com doença tricompartimental do joelho e aqueles submetidos à osteotomias para tratamento de sequelas de fraturas. Após a cirurgia, a inclinação tibial proximal aumentou, em média, 1,7 graus (p OBJECTIVE: To measure the variation in posterior tibial slope angle and patellar height in patients who underwent proximal tibial valgus-producing osteotomy using the medial-opening wedge technique. METHODS: Anteroposterior panoramic radiographs of the lower limbs and lateral radiographs of the knee obtained before and after tibial valgus-producing osteotomy on 46 patients with unicompartmental arthrosis of the knee were analyzed. RESULTS: In 23 patients, an external fixator was used to gradually apply a medial-opening wedge; and in the other 23, a blocked plate with a stop bar was applied as a fixation method. Patients with tricompartmental knee disease and those who underwent osteotomy to treat fracture sequelae were excluded from this study. After surgery, the mean increase in the tibial slope was 1.7 degrees (p < 0.01) in the group in which the blocked plate with a stop bar was used; and 2.7 degrees (p < 0.05) in the group in which the external fixator was used. There was no statistical difference between the groups regarding the increase in the posterior tibial slope. CONCLUSION: The patellar height did not present any change in the cases in which the plate was used, when measured using the Insall-Salvati method, but it presented a decrease in 11 cases (47.8%) when the Caton-Dechamps method was applied. The same tendency was observed regarding change in the patellar height in the cases in which the external fixator was used, such that a decrease was observed in eight cases (34.7%) only when measured using the Caton-Dechamps method

Distal femoral cut in total knee arthroplasty in a Brazilian population

OBJECTIVE: To determine the ideal angle for making the distal femoral cut in total knee arthroplasty in a Brazilian population.METHODS: Panoramic radiographs of the lower limbs bearing weight from 79 patients (57 women and 22 men) were studied, totaling 107 knees with an indication for total knee arthroplasty. The femoral anatomical axis, femoral mechanical axis and cervical-diaphyseal angle were traced out. The angle of the femoral cut was determined from the meeting point between the femoral anatomical and mechanical axes. The ideal degree of femoral valgus was compared between men and women and between knees presenting varus and valgus alignment of the lower limb. The ideal distal femoral cut was also correlated with the cervical-diaphyseal angle.RESULTS: The ideal femoral valgus angle ranged from 4.2 to 8.6 degrees, with a mean of 6.3 degrees. There was no statistically significant difference in the distal femoral cut between patients with coronal varus and valgus alignment (p = 0.180). Comparing men and women, there was no statistically significant difference regarding the ideal femoral valgus between the groups (p = 0.057). The cervical-diaphyseal angle presented an inverse relationship with the distal femoral cut.CONCLUSIONS: The mean angle between the femoral mechanical and anatomical axes was 6.3 degree. Neither preoperative coronal alignment nor sex had any influence on the distal femoral cut. The cervical-diaphyseal angle presented an inverse relationship with the distal femoral cut
