Septic coxitis is a rare disesase which can be caused by a variety of pathogens. Primary and secondary coxitis can be differentiated depending on the etiology. In the initial stages the diagnosis is difficult but a delay in making the correct diagnosis or delayed therapy can result in fatal consequences for the patient, therefore, therapy should be started even in cases of suspected septic coxitis. Septic coxitis is classified into four stages depending on the arthroscopic findings. The best results are usually achieved by a combination of arthroscopic lavage and antibiotic therapy.
