Prospective 5- to 6-year follow-up study of a cementless acetabular cup.
Twenty-seven patients in whom the Ti-Bac acetabular cup (Zimmer, Warsaw, IN) was placed were examined 5 to 6 years after surgery. The cup was inserted line to line, after reaming without further fixation. In all operations, a cemented Müller straight-stem Protazul femur stem (Zimmer) was used. The patients had good pain relief and improved mobility after the operation. Radiographically, only one hip showed radiolucency in the bone-metal interface after 5 to 6 years. One patient was reoperated 3 days after surgery because of dislocation of the acetabular cup. Apart from this, there were no signs of aseptic loosening of any of these uncemented cups.
