title: [Clinical and metallographic evaluation of the causes of mechanical loosening of revision baskets Recon Ring--description of 3 cases].
abstract: Aim of this study is to assess the causes of mechanical loosening of revision Recon Ring baskets (Aesculap / BBrown, Germany). This analysis was done by assessing the circumstances of baskets loosening of revision in 3 patients. Intraoperative images and radiographs of patients with these clinical complications were analyzed, and removed damaged bins and bolts of revision metallographic expertise. It was found that the most likely cause mechanical damage to the implant was originally unstable or re-fixing their ischial part, causing movable canopy closer to the basket is balanced by the screws and in turn causing fracture or bending arms, and follow-up baskets of hip bone loss. Our observations suggest that the most important is proper attachment of acetabular basket, especially his arm sciatic.
