[Treatment decision for femoroacetabular impingement syndrome : Differential diagnostic considerations and the introduction of a stage concept for treatment].

Anamnestic findings, clinical examination and radiological findings are presented, as well as thoughts for differential diagnosis and the introduction of a stage concept for treatment. The treatment of FAI is based on a patient's individual symptoms, the clinical examination and radiological findings. The procedure depends on a number of facts. Individual conditions have to be considered, and the procedure needs to follow principal rules. Therefore, we propose a standard for treatment, which ranges from purely conservative measurements to extensive surgery.
