Factors associated to avascular necrosis of the femoral head and non-union in patients younger than 65 years old with displaced femoral neck fractures treated with reduction and internal fixation.

Pocos estudios han evaluado el tratamiento de las fracturas desplazadas de cuello femoral en pacientes menores de 65 años de edad, y no han sido claramente definidos los factores de riesgo para necrosis avascular o no-unión dentro de este rango de edad. Para determinar los factores asociados a la necrosis avascular de la cabeza femoral (AVN) y no-unión en pacientes menores de 65 años de edad con fracturas desplazadas del cuello femoral tratados con reducción y fijación interna, se realizó un estudio retrospectivo de 29 fracturas desplazadas del cuello femoral en 29 pacientes consecutivos tratados en una sola institución. La influencia de la edad, la energía del trauma, tipo de reducción, y el tiempo entre la fractura y el tratamiento en desarrollo de la AVN y no-unión fueron evaluados. Los pacientes que desarrollaron NAV fueron significativamente mayores y sufrieron un trauma de más baja energía que en los casos sin AVN. Ninguna variable fue asociada con la no-unión. La regresión logística determinó que sólo la edad se asoció de forma independiente a NAV. La edad es un buen predictor para el desarrollo de NAV, con un C-estadístico de 0.861, y un mejor corte-determinado en 53,5 años. Conclusión: Los pacientes de entre 53,5 y 65 años presentan un riesgo más alto de NAV. La artroplastia primaria se debe considerar en este subgrupo.

Conceptual Rapprochement and the Analysis of the Historical, Normative and Jurisprudential Treatment of the Rural Workers, as Regards the Need for Special Protection

This article aims to present an approach to the issue of farm or rural zone workers, including a labour law study of agrarian legal decisions, so as to demonstrate their importance in respect to social, economic and cultural rights in Colombia. The study will serve to illustrate through the history, the applicable law and the jurisprudence, the different ways in which farmers have been treated from the time of the origin until the arrival of modern systems of industrialization. It calls into question the effectiveness of existing laws and the role of the courts, in spite of globalization, to maintain the minimum rights and guarantees of farm workers who are considered to be a vulnerable population. In conclusion, this study seeks to illustrate the current role of the Labor law and the National Health Service in the area of demonstrating of the existence or absence of mechanisms to protect workers in rural areas and the need to create some mechanisms that involve social justice given its prime importance in the Constitution of 1991.

The institutional environment and its influence on political options to Protect Winnipeg’s Female garments Workers against the impact of globalization

The principal objective of this paper is to identify the relationship between the re­sults of the Canadian policies implemented to protect female workers against the impact of globalization on the garment industry and the institutional setting in which this labour market is immersed in Winnipeg. This research paper begins with a brief summary of the institutional theory appro­ach that sheds light on the analysis of the effects of institutions on the policy options to protect female workers of the Winnipeg garment industry. Next, this paper identi­fies the set of beliefs, formal procedures, routines, norms and conventions that cha­racterize the institutional environment of the female workers of Winnipeg’s garment industry. Subsequently, this paper descri­bes the impact of free trade policies on the garment industry of Winnipeg. Afterward, this paper presents an analysis of the ba­rriers that the institutional features of the garment sector in Winnipeg can set to the successful achievement of policy options addressed to protect the female workforce of this sector. Three policy options are considered: ethical purchasing; training/retraining programs and social engage­ment support for garment workers; and protection of migrated workers through promoting and facilitating bonds between Canada’s trade unions and trade unions of the labour sending countries. Finally, this paper concludes that the formation of isolated cultural groups inside of factories; the belief that there is gender and race discrimination on the part of the garment industry management against workers; the powerless social conditions of immi­grant women; the economic rationality of garment factories’ managers; and the lack of political will on the part of Canada and the labour sending countries to set effective bilateral agreements to protect migrate wor­kers, are the principal barriers that divide the actors involved in the garment industry in Winnipeg. This division among the prin­cipal actors of Winnipeg’s garment industry impedes the change toward more efficient institutions and, hence, the successful achievement of policy options addressed to protect women workers.
