[Radiography assessment of the hip joint after the implantation of cementless ceramic cup and metal cup]

Radiographic assessment of the hip joint and clinical results after implantation of cementless Mittelmeier ceramic cup and metal Parchofer-Munch cup are presented. Material included 151 hips (56 ceramic cups and 95 metal cups). A-P radiograph and Engh criteria served for radiological assessment of the cup. Vertical, horizontal and angular migration as well as radiolucency in three De Lee zones were evaluated on postoperative and follow-up radiographs. Vertical migration and increased radiolucency within III De Lee zone were the most frequent findings. All types of migration and increased radiolucency in De Lee zones were observed more often after ceramic cup implantation.
