Total shoulder arthroplasty with hybrid fixation of glenoid components consisting of cementless porous metal pegs or cage along with cemented backside polyethylene surface: a systematic review

AbstractRecently, hybrid glenoid components have been developed, consisting of cementless highly porous metal central peg, monoblock keel or cage along with cemented backside polyethylene surface. The aims of this study were twofold: (1) to determine the revision and complication rates of hybrid glenoid components, consisting of porous metal pegs or coatings attached to the polyethylene, for aseptic loosening in TSA and (2) to evaluate the rate of radiolucent lines in patients who underwent TSA with hybrid glenoid components consisting of porous metal pegs or coatings attached to the polyethylene. The US National Library of Medicine (PubMed/MEDLINE), EMBASE and the Cochrane Database of Systematic Reviews were queried for publications utilizing the following keywords: “hybrid” OR “bone-ingrowth” OR “bone ingrowth” AND “TSA” OR “total” AND “shoulder” AND “arthroplasty” OR “replacement”. Five articles were included for analysis (470 operated shoulders, mean follow-up: 47.5 months). The overall weighted mean modified methodology Cole man score was 51.2/100, indicating a moderate level of overall methodological quality. The survival rate of hybrid glenoid components was 97.4% (458 out of 470 cases), while the rate of glenoid-related complications was 2.8% (13 cases). Finally, there were 54 cases (out of 313 reported; 17.3%) with glenoid radiolucency (none of them required revision). TSA with hybrid fixation glenoid components was associated with hi...
