A 66-year-old female patient who had an infected total hip arthroplasty. A The preoperative X-ray showing a Paprosky IIIB defect. B The pelvic continuity was confirmed on CT scans. C The “hybrid cup” reconstruction technique was used with 3 porous shells. The smaller middle cup was eccentrically cemented into the medial TM revision shell to fill the sideward defects. A larger porous cup was then impacted onto the “cup-in-cup” construct (out diameters of the shell from medial to lateral: 66 mm; 54 mm; and 62 mm)
