[Orthopedic problems in hemophilia. Pathophysiology and results of operations (author's transl)].

During the last 3 years we have treated over 400 patients with severe hemophilia A or B of all ages. They were looked after by the Institute for Experimental Hematology and Blood-Transfusion of the University at Bonn, for prevention, rehabilitation and operation. The specific pathophysiology of disability of the hemophiliac is shortly outlined, the chances of operative rehabilitation and their indications are discussed. The results show that--with experience--extensive operative rehabilitation can be achieved also in hemophiliacs.
