title: [Cement-free Zweymüller hip system. Results of a 5-year follow-up study].
abstract: 85 patients with 96 cementless pressfit hip implants were followed over a period of at least 5 years postoperatively. Average Harris score was 87.5 points. One socket had to be exchanged because of aseptic loosening. Additionally, 5 implants developed radiolucent lines, only one of them totally around the socket. In no case an exchange of the stem was necessary; one stem initially sank by 4 mm axially but was stable at the last follow-up investigation. Only one patient personally is dissatisfied with the outcome of the operation. In no case, implant specific complications such as breakage of the implant, breakage or crack of the stem, or shattering of the pelvic girdle by acetabular-screwing could be observed.
