Abstract

The authors present a study that includes 350 patients affected with loosening of hip arthroplasty and submitted to revision with a Wagner LS stem at the 4th Division of the Rizzoli Orthopaedic Institute. Several different types of cotyle (Fitek, Wagner, Standard Cup, cemented cotyle with support ring, Octopus system) were used depending on the anatomopathologic findings, combined with autoplastic grafts. Staging and grading of loosening were based on the four G.I.R. grades. A clinical evaluation of results was based on the Merle D'Aubigné parameters modified by Charnley. For radiographic evaluation the De Lee Charnley areas were studied for cotyle, the Gruen areas for the femoral stem. Overall, good results were obtained in 175 patients, fair in 137, poor in 38.
