Qualitatively, the trends observed for cemented components also appear to be applicable to modular acetabular components, evaluated using current computer-assisted wear measurement techniques (Tables 5.2 and 5.3, and Figure 5.11). The box and whisker plots shown in Figure 5.11 compare the linear... [Pg.85]

Distribution of LWRs and VWRs estimated in a first-generation modular acetabular component design (Harris-Gallante Zimmer Warsaw, IN). These graphs show the tendency for the wear rates to decrease with implantation time. Results are compared based on analysis of A-P radiographs alone (two-dimensional), as well as based on the combined analysis of A-P and lateral radiographs (three-dimensional).

Sulzer s second-generation MOM designs incorporated a CoCr articulating surface, but the acetabular component consisted of a modular shell and an UHMWPE liner embedded with a CoCr insert. A cross-section of the contemporary "sandwich" type design, distributed under the trade name METASUL (Centerpulse Orthopedics, Winterthur, Switzerland) is illustrated in Figure 6.5. [Pg.98]

The head of the femoral component then articulates with an ion-bombarded, HDPE, high walled, acetabular liner which fits iato a screwed ia, machined, titanium, chromium—cobalt—molybdenum or vanadium—aluminum metallic alloy hydroxyapatite-coated acetabular shell/cup. Each of the separate parts of the modular system for total hip arthroplasty is manufactured ia several different sizes. [Pg.189]
