Abstract
Background:Hybrid glenoid components in total shoulder arthroplasty (TSA) utilize both polyethylene and metal components to provide short-term stability and long-term biologic fixation through bone ingrowth.Questions/Purpose:We sought to systematically review the literature for studies that assessed outcomes of TSA performed using hybrid glenoid components.Methods:PubMed, Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Embase were searched systematically for articles measuring clinical and patient-reported outcomes and rates of complication and revision following TSA using a hybrid glenoid component.Results:Seven studies with 593 shoulders were included in this review. The mean age of patients was 65 ± 1 years, and 46% of the population was male. Mean follow-up was 50 months (4.2 years). The overall complication rate was 7% and rate of revision was 2.5%; glenoid radiolucency was present in 33% of shoulders at mean follow-up of 50 months. Mean improvements in forward elevation, external rotation, internal rotation score, and abduction were 49°, 28°, 2 points, and 42°, respectively. Mean improvements in Constant, American Shoulder and Elbow Surgeons (ASES), and University of California, Los Angeles (UCLA) scores were 36 points, 52 points, and 17 points, respectively.Conclusion:Our review found that TSA using hybrid glenoid components results in low rates of complication and revision at early follow-up. Long-term studies are warranted to understand more fully the role of hybrid glenoid components in TSA.

Summary
Total shoulder arthroplasty (TSA) is increasingly being used as the procedure of choice for advanced shoulder pathologies, such as osteoarthritis and rheumatoid arthritis [24]. The gold standard for TSA is the use of all-polyethylene glenoid components, with cementing techniques used to achieve early implant stability [11,13,22,25]. While this design offers initial stability, symptomatic glenoid loosening over time is common and may require revision surgery [19]. Metal components have demonstrated excellent outcomes in hip and knee arthroplasty, via both cemented and press-fit techniques, and this popularized the use of metal-backed glenoid components in an attempt to address the long-term concerns of all-polyethylene glenoid. Our hypothesis was that hybrid glenoid components offered greater initial stability and had lower complication rates than all-polyethylene and metal-backed glenoid components
