[Conservative treatment of aseptic necrosis of the femoral head. Are there evidence-based therapy concepts?].

Osteonecrosis of the femoral head is a locally destructive disease with a multifactorial genesis. The majority of patients are men between 35 and 45 years of age, who are increasingly reduced in their quality of life and career. As these patients are in the middle of their careers, osteonecrosis of the femoral head is even of increasing interest for the national economy. It is therefore of major interest to reduce the costs as well as the time for its therapy. Since conservative treatment is discussed controversially, it was the aim to focus on the current literature according to the criteria of evidence-based medicine and to prove the importance of conservative treatment of femoral head osteonecrosis.
