Demographics of extra-articular calcaneal fractures: Including a review of the literature on treatment and outcome
Introduction: Extra-articular calcaneal fractures represent 25-40% of all calcaneal fractures and an even higher percentage of up to 60% is seen in children. A disproportionately small part of the literature on calcaneal fractures involves the extra-articular type. The aim of this study was to investigate the incidence of extra-articular calcaneal fractures in a Level 1 trauma centre, define the distribution of the various types of fractures and compare patient demographics between extra- and intra-articular calcaneal fractures. In addition the literature was reviewed for the most common types of extra-articular calcaneal fractures with regard to incidence, treatment and clinical outcome. Methods: The radiological records between 2003 and 2005 were reviewed for intra- and extra-articular calcaneal fractures. Patient gender-distribution and age were compared. A literature search was conducted for the treatment of extra-articular calcaneal fractures. Results: In this 3-year study period a total of 49 patients with 50 extra-articular calcaneal fractures and 91 patients with 101 intra-articular fractures were identified. The median age for the first group was 32.7 years, and for the second group 40.3 years; P = 0.04. Male predominance was significantly less pronounced for extra-articular (63%) compared with intra-articular fractures (79%; P = 0.04). Conclusion: One-third of all calcaneal fractures are extra-articular. Significant differences exist between the intra- and extra-articular groups, in terms of lower age and male-female ratio. The literature study shows inconsistencies in treatment options, but most extra-articular fractures are well manageable conservatively
Animal Models of Experimental Myopia: Limitations and Synergies with Studies on Human Myopia
Le quartier Graslin et ses acteurs.
Le plan de Nantes signé en 1789 par Nicolas Sauzeau, exprime bien la dualité essentielle du quartier dont Jean-Joseph-Louis Graslin s’est fait le promoteur depuis une dizaine d’années : un lotissement privé articulé avec le plan de la ville (fig. 48). La pleine valeur de l’opération de Graslin ne pouvait éviter une concertation avec la communauté de ville qui prenne en considération son projet annoncé comme « vues patriotiques ». Si, dans plusieurs mémoires justificatifs et défensifs, l’écono..
