[Implantation of 110 total hip joint endoprosthesis using the Zweymüller method].

The authors discuss in the submitted paper the advantages and disadvantages of cemented and non-cemented endoprostheses, type Zweymüller. They evaluate the medium-term results (one half to 5 years) after surgery in 92 patients from a total of 121 operations in 110 patients (11 bilateral). As to indications, the first place was held by so-called dysplastic coxarthroses, followed by post-traumatic coxarthroses and rheumatoid arthritis incl. the juvenile type. The results of these operations were after an average of 18.27 months following operation according to the DMS evaluation of Merle d'Aubigné and Postel excellent and good in 89%. The authors recorded a relatively small percentage of complications, associated in particular with the replacement of the acetabulum in three patients and the replacement of the femoral component in two patients.
