A 51-year-old male patient who had previous failure of a total hip arthroplasty. A A Paprosky IIC defect on the right hip. B The “cup-on-cup” reconstruction technique was performed with 2 tantalum TM shells. The larger tantalum cup was impacted onto the medial TM revision shell and a rigid fixation was achieved based on the lateral acetabular rim (out diameters of the shell from medial to lateral: 52 mm and 58 mm)
