    Rolando Fractures

    No full text
    The term Rolando fracture was described for the first time in 1910 by Silvio Rolando, an Italian surgeon. The eponym is used to describe a comminuted articular fracture of the base of the thumb metacarpal, while partial articular fractures at the volar-ulnar base of the thumb metacarpal are referred to as Bennett fractures. The former describes more comminuted intra-articular patterns through the base, generating the classically described "Y" or "T" morphologies. The latter is distinguished by its 2-part articular fracture pattern including the nondisplaced volar-ulnar fragment which is held in place by its ligamentous attachment to the trapezium, known as the anterior oblique ligament. This activity reviews the classification, evaluation, and management of Rolando fracture, and also illustrates the evaluation and management of Rolando fracture and reviews the role of the interprofessional team in improving care for patients with this condition. Objectives: Describe the pathophysiology of Rolando fracture. Describe the typical imaging findings associated with Rolando fracture. Review the treatment considerations for patients with Rolando fracture. Explain the importance of the interprofessional team as it pertains to improving care coordination among the interprofessional team members when treating Rolando fracture

    AQUINO, Rolando, CORNEJO, Fanny M. y HEYMANN, Eckhard W. Primate abundance and habitat preferences on the lower Urubamba and Tambo rivers, central-eastern Peruvian Amazonia. Primates. [en línea]. 2013, vol. 54, no. 4, p. 377-383. ISSN 0032-8332.We report information on population density, group size, and habitat preferences of primates along the lower Rio Urubamba and in the Rio Urubamba-Rio Tambo interfluvium, in central-eastern Peruvian Amazonia, an area that has been little explored with regard to its primate fauna. During 425 km of transect walks in October-November 2008 and April-May 2009 totally 174 groups of nine primate species were encountered, the most common being Callicebus brunneus (45 groups), Saguinus imperator (41 groups), and Aotus nigriceps (26 groups). Group sizes were smallest for A. nigriceps and C. brunneus (mean of 2.8 and 2.9, respectively) and largest for Saimiri boliviensis (mean 15.6). Population densities were lowest for Lagothrix cana (3.3 individuals/km(2)) and highest for A. nigriceps (31.1 individuals/km(2)). Groups of C. brunneus, S. imperator, S. boliviensis, Cebus albifrons, and Cebus apella were most frequently (83 % of sightings) encountered in semi-dense or in open primary forest that included stands of bamboo (Guadua sarcocarpa) or where bamboo was a very common species

    AQUINO, Rolando, CORNEJO, Fanny M., PEZO, Etersit [et al.]. Distribution and abundance of white-fronted spider monkeys, Ateles belzebuth (Atelidae), and threats to their survival in Peruvian Amazonia. Folia Primatol [en línea]. 2013, vol. 84, no. 1, p. 1-10. ISSN 0015-5713.The white-fronted spider monkey, Ateles belzebuth, is listed as ‘Endangered’ according to the IUCN classification. In Peru it is found in the departments of Loreto, San Martín, Amazonas and Cajamarca, but detailed data on its geographic distribution, population densities and conservation status are scarce. In order to obtain such information, we conducted transect censuses on the Río Aushiri and Río San Antonio (right bank of Río Napo), and between the Río Curaray and the Río Arabela and Río Nashiño, respectively, and made additional explorations on the northern and southern banks of the Río Marañón. We obtained 48 sightings along 761 km of census transect. Group size and population densities were lower in an area with high hunting pressure compared to areas with medium or low hunting pressure. Besides hunting, increasing deforestation is a major threat to the survival of A. belzebuth in Peruvian Amazonia
