The Columbus® Revision endoprosthetic system is bearing the CE-mark. This means that within the scope of this observational study the patient will not be subjected to any additional stressful, study-related medical examinations or treatment measures. The treatment will be carried out exclusively according to medical standards. The study therefore only serves the purpose of observing this standard-compliant treatment and specifically documenting it scientifically.
