Flecher et al. [35]20082358.23A, 3B (8 pelvic discontinuity cases)Revision shell with or without augments35No mechanical failure
Suitable options for type III defects and alternative options to bone graft and cages

Van Kleunen et al. [42]200990 (50/40)59Minimum 2ARevision shell with/without augments; 2 antiprotrusio cage cases458 revisions for infection and 1 case for instability; no revision for aseptic loosening

Lakstein et al. [36]200953 (24/29)63Less than 50% of contactTrabecular metal cups452 failed cup cases (4%); other 2 cups with radiological signs of aseptic loosening; 4 dislocation cases, 1 sciatic nerve palsy case

Jafari et al. [43]2010283 (128/155)69MixedTantalum cup (79) versus titanium cup (207)43.6Failure rate: titanium 8%, tantalum 6%
Higher failure rate in massive bone deficiency for titanium cups
Radiographically better fixation for tantalum cups

Flecher et al. [37]201071 (41/30)60MixedTantalum cup with/without augments48No radiolucent lines, 3 revisions for instability
Good restoration of rotation center of the hip

Fernández-Fairen et al. [44]2010263 (150/113)69.5MixedMonoblock or revision shell with or without augments73.685.9% of satisfied patients
All cups were stable, no revision, no radiolucent lines

Lachiewicz and Soileau [19]201037 (19/18)65.13Tantalum cups and augments39.697% of well-fixed component; 1 mechanical failure; 7 revisions (dislocation, infection, periprosthetic fracture)

Ballester Alfaro and Sueiro Fernandez [27]201019 (12/7)633A and 3BCup-cage constructs26No mechanical failures
Buttress tantalum augments, with cup-cage construct for severe bone defects can be a viable option

Skyttä et al. [45]2011827 (522/447)69.1N/ATrabecular metal revision shell36The 3-year overall survivorship was 92%; 2% revision for aseptic loosening; each additional year in age decreased the risk of revision by 2.4%
