This 2013 narrative review by Sheth et al. systematically covers the preoperative evaluation and full reconstruction armamentarium for acetabular bone loss in revision THA, using the Paprosky and AAOS classification systems to match defect severity to technique.
When you encounter a failed acetabular component in revision THA, classify the defect using Paprosky before you select your construct: Types I–IIC support a noncemented hemispheric shell with screws; IIIA adds porous metal augments; IIIB or pelvic discontinuity escalates to cup-cage or custom triflange.
Preoperative CT with 3D reconstruction is essential when the component is medial to the Kohler line to map proximity to pelvic vessels.
