The literature article titled, "salvage reverse total shoulder arthroplasty for failed anatomic total shoulder arthroplasty: a cohort analysis" written by r.Stephen otte, md, amanda j.Naylor, ma, kassandra n.Blanchard, ma, jourdan m.Cancienne, md, william chan, ma, anthony a.Romeo, md, grant e.Garrigues, md, and gregory p.Nicholson, md published by elsevier journal of shoulder and elbow surgery 2020 was reviewed.The article's purpose was to analyze the results of rtsa (revers total shoulder arthroplasty) as a revision salvage procedure for failed tsa (total shoulder arthroplasty) and identify factors that influenced those outcomes.Data was compiled from 75 patients (32 men and 43 women).It is noted that depuy products are listed amongst the failed tsa cases along with non depuy products.Finding results were the rtsa can improve pain, function and quality of life measures the article does not identify cement manufacturer.Involved tsa constructs were global/global ap (qty 7), global cap (qty 1), global unite (1).Constructs utilized in revision to rsa were not identified.The article reports majority of patients had multiple indications for revision rtsa, , and the article does not identify which products are associated with the revision reasons.Therefore exact quantities associated with each specific adverse event cannot be determined.Depuy products: global ap stem, global ap head, global ap glenoid (also utilized with cap in tsas), global unite stem, global unite proximal body, global unite cup, global unite glenosphere, global unite metaglene, 2 locking screws, 2 non-locking screws, global cap humeral head.Reasons for revision of tsa: septic loosening (no further information provided), glenoid loosening, humeral loosening, pain, rotator cuff failure, unstable arthroplasty.
