摘      要：Background Kashin-Beck disease （KBD） is a chronic,degenerative osteoarthropathy that causes severe skeletal *** many researchers have proven that almost all KBD patients who showed an increaseing proximo-distal gradient had radiographic abnormalities of the ankle,few detailed description of radiographic changes in the ankles of patients with KBD has been reported,especially for variable measurements of ankle *** purpose of this study was to demonstrate the radiographic characteristics of the ankles of adult KBD *** One hundred and eighteen adult KBD patients from september to October 2010 in Rongtang county in China were examined with lateral radiographs of the right *** morphological abnormalities in the talus,calcaneus,navicular bone,distal tibia,and joint space were analyzed,and the calcaneus length,height,length-height ratio,tuber angle,front angle,plantar angle,and distal tibia anteroposterior （AP） length were measured using Riepert＇s *** Eighty-one patients （68.6％） had abnormal ankle radiographs; 72 （88.9％） patients had talus changes,69 （85.2％） patients had calcaneus changes,28 （34.6％） patients had navicular bone changes,and 48 （59.2％） patients had distal tibia *** 118 KBD patients,the average calcaneus length was 7.4 cm,height was 4.3 cm,and the length-height ratio was *** calcaneus tuber angle was 28.2°,front angle was 38.0° and the plantar angle was 74.2°.The distal tibia anteroposterior length was 4.05 *** with 50 normal adults （control group）,significant differences were found for the calcaneus length,the calcaneus length-height ratio,and the distal tibia AP *** Patients with KBD have characteristic abnormalities on ankle radiographs; talus depression and deformity,calcaneus shortening deformity,and distal tibia deformity with AP length widening were the most typical changes.
