Abstract: In Total Hip Arthroplasty (THA) there is so far no device on the market that enables surgeons to use a cemented acetabular component with the possibility of different inlays. We present an acetabular metal backed shell that has been specifically developed for this purpose. Basis of our approach was to gain all profits from the cement-less method of hip replacement where, after press-fit fixation of the metal-cup, a great variety of inlays can be attached. Polyethylene, ceramic- or snap-inlays-even with different geometries (straight or asymmetric) - can be combined with different head-diameters (28/32/36 mm). The presented modular cementable acetabular component system (C-MIC), newly developed and utility patented in collaboration with ESKA Implants GmbH (Luebeck, Germany), combines the advantages of both methods.
