    Midterm results after operatively stabilised shoulder dislocations in elderly patients

    Anterior shoulder dislocation is frequently seen in young patients. The therapeutic regime in elderly patients after shoulder dislocation is less clearly defined. The aim of this study was to compare the clinical benefit of operative stabilisation following anterior shoulder dislocation in young versus elderly patients. Seventy-two patients with anterior shoulder dislocations were allocated into two groups. Group 1 (> 40 years of age) consisted of 23 patients, and group 2 (< 40 years of age) consisted of 49 patients. Operative stabilisation resulted in a significant reduction in recurrence rate in both groups. However, the clinical functional results measured by the Constant score, Rowe score and disabilities of the arm, shoulder and hand (DASH) score revealed significantly better outcomes in the younger (group 2) than in the older group (group 1). These results indicate that while operative stabilisation is equally effective in reducing recurrent shoulder dislocation in the elderly functional outcomes are not as good as in younger patients

    This review synthesizes the tectonomagmatic evolution of the southern Central andNorthern Patagonian Andes between 35°30?S to 48°S with the aim to spotlight earlycontractional phases on Andean orogenic building and to analyze their potential drivingprocesses. We examine early tectonic stages of the different fold and thrust belts that composethis Andean segment. Additionally, we study the magmatic arc behavior from a regionalperspective as an indicator of potential past subduction configurations during critical tectonicstages of orogenic construction. This revision proposes the existence of a continuous large-scaleflat subduction with a similar size to the present-largest flat-slab setting on earth. This particularprocess would have initiated diachronically in late Early Cretaceous times and achieved fulldevelopment in Late Cretaceous to earliest Paleocene, constructing a series of fold - thrust beltson the retro-arc zone from 35°30?S to 48°S. Furthermore, dynamic subsidence focused at theedges of the slab flattening before re-steepening beneath the foreland zone may explain suddenpaleogeographic changes in Maastrichtian-Danian times previously linked to continental tiltingand orogenic loading during a high sea level global stage.Fil: Gianni, Guido Martin.
