[Our Experience in the Revision Surgery of THR.].
The authors present their experience in the revision surgery of THR. Most often it was the case of aseptic loosening of the acetabulum, the femoral component or both components (67 %), lytic radioluscence or even lysis in the region of implants, fissures even fractures of the femur and septic loosening. They evaluate the results of revision surgeries of THR for a 5-year period in 106 patients after Merle dAubigne and Postel: excellent result was achieved in 33 %, good in 39 %, average in 19 % and a poor result in 9 %. The authors emphasize in case of primary surgery the importance of indication criteria, age of the patient, appropriate choice of the type of implant, evaluation of the immunological condition of the patient. In revision surgeries of aseptic loosening of the implant and bone defects of the medial acetabular wall efficient was mainly the application of bone grafts and cementless acetabular cup of the Harris-Galante, Zweymüller or Balgrist type. Periprothetic fractures of the femur should be treated by internal fixation and Wagner revision stem. In case of septic loosening the endoprosthesis was extracted or a two-phase revision surgery performed. Key word: THR revision surgery, aseptic loosening, bone defects, Wagner revision stem.
