[Complications in total hip arthroplasty with double mobility prosthesis: Experience in a third level hospital].

Introduction: total hip arthroplasty (THA) is a successful surgical intervention for end-stage hip arthritis, however, it is not extent for complications. The risk of instability after THA with conventional design is up to 7% for primary procedures and 5-20% for revisions. The purpose of this study is to document the complications that occur with the double mobility prosthetic design.
