Background: Hip fractures belong to the most frequent fractures of elderly people. The treatment follows a specific algorithm that focuses on the medical as well as the social situation of these patients. Despite modern operative techniques and implants complications may occur. They may be distinguished into two groups: local complications and systemic complications Especially local complications (cut out of the femoral head screw) are the reason for revision surgery. Surgery (“salvage procedures”) may only be performed after critical analysis of the local situation and individual planning of the revision procedure. This article outlines the tactical course of action in these cases. Keywords: Hip fractures – complication – salvage procedure – therapeutic algorithm.
