Acetabular pressfit fixation depends on rigid initial fixation, subchondral bone preservation, and close apposition to allow biologic interface incorporation. A hemispherical cup with a 1 to 2 mm pressfit offers optimal fixation and adjunct fixation with screws or pegs appears to be limited. Pressfit continues to be the ideal fixation choice for most patients.
髋臼压配固定取决于初始的牢固固定、软骨下骨的保留以及紧密贴合以实现生物界面融合。一个具有1至2毫米压配的半球形髋臼杯可提供最佳固定,而使用螺钉或栓子的辅助固定似乎有限。压配仍然是大多数患者的理想固定选择。
