We queried PubMed/Medline, Embase, Web of Science, and Cochrane databases to identify articles reporting clinical outcomes of RSA with LDT or lateralized RSA alone performed in patients with preoperative ER ≤0°. Our primary outcomes were active ER, active forward elevation (FE), Constant score, and the incidence of complications.<h4>Results</h4>We included 12 RSA with LDT studies with 188 shoulders and 4 lateralized RSA without transferClinics in shoulder and elbow464-478https://www.ebi.ac.uk/biostudies/studies/S-EPMC11615459biostudies-literatureOutcomes of lateralized reverse total shoulder arthroplasty versus latissimus dorsi transfer for external rotation deficit: a systematic review and meta-analysis.PMC11615459Bindi VERakauskas TRKing JJHao KAGutowski CTWright JOWright TWHones KMSchoch BSWerthel JDSimcox TfalseOutcomes of lateralized reverse total shoulder arthroplasty versus latissimus dorsi transfer for external rotation deficit: a systematic review and meta-analysis.<h4>Background</h4>To compare clinical outcomes following lateralized reverse shoulder arthroplasty (RSA) versus RSA with latissimus dorsi transfer (LDT) in patients with poor preoperative active external rotation (ER).<h4>Methods</h4>We performed a systematic review per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
