Anatomic healing of greater tuberosity improves range of motion and functional outcomes after reverse total shoulder arthroplasty for proximal humerus fractures. An updated systematic review and meta-analysis on 21 studies.

Background: Reverse shoulder arthroplasty (rTSA) is increasingly being used to treat complex proximal humerus fractures, especially in the senior population. The question of whether it is worthwhile to repair the greater tuberosity (GT) after rTSA for proximal humerus fractures still needs to be answered.

Methods: A systematic review was performed on PubMed, Scopus, Cochrane library and EMBASE, for studies available up to February 2024 focused on tuberosity repair following rTSA for proximal humerus fracture and reporting clinical outcomes and range of motion (ROM) between patients with anatomic GT healing and patients with malunion or nonunion of GT.
