摘要

Custom triflange implants are used today along with standard antiprotrusio cages and modular revision systems for difficult revision cases with important acetabular defects (Paprosky II C or III). This paper presents a new personalised acetabular cage in regards to the design procedure and realisation applied on a specific patient case. The cage proposed is similar in construction to a Burch Schneider cage and tries to combine the advantages of custom design with the versatility and cost efficiency of the antiprotrusio cages. The design procedure is presented starting from patient information acquisition and model build up, continuing with the necessary design parameters and design features for the cage and drill guide and ending with an experimental realisation of the cage and guide trough 3D rapid prototyping.
