[The ochronosis disease picture and conservative and operative therapy. Presented in relation to a case report]

Ochronosis leads very early, already in the fourth decade, to osteoarthritic alterations, mainly of the large joints. As the treatment has to be symptomatic, joint prosthesis is often inevitable. We report about a case history of a patient with coxarthrosis and basic alterations by ochronosis. In spite of a bone structure similar those of osteomalacia, we were able to implant a cementless total hip prosthesis in the left hip joint.
