The entity of greater tuberosity fractures (GTF) has rarely been studied in the literature. The purpose of this study was to analyze the outcome of postoperative greater tuberosity fractures after RTSA compared to a matched control group. The main findings of this study are that a GTF after RTSA is associated with worse clinical outcome scores (mean absolute CS 50 \u00b1 19 (p = 0.032); SSV 63% \u00b1 26 (p = 0.022); mean force 1 kg \u00b1 2 kg (p = 0.044)) compared with the control group (mean absolute CS 62 \u00b1 21; SSV 77% \u00b1 29; mean force 2 kg \u00b1 2 kg). In terms of postoperative range of motion, the fracture group was significantly worse in terms of external rotation (17\u00b0 \u00b1 19\u00b0 vs. 30\u00b0 \u00b1 19\u00b0 (p = 0.029)). Internal rotation, flexion, as well as abduction of the shoulder appear to be unaffected (internal rotation GTF 4 \u00b1 2, control group 5 \u00b1 3 (p = 0.138); flexion GTF 102\u00b0 \u00b1 28\u00b0, control group 114\u00b0 \u00b1 27\u00b0 (p = 0.160); abduction GTF 109\u00b0 \u00b1 42\u00b0, control group 120\u00b0 \u00b1 39\u00b0 (p = 0.317)).<\/jats:p>","DOI":"10.3390\/jcm12031153","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T05:33:53Z","timestamp":1675229633000},"page":"1153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Greater Tuberosity Fractures after RTSA: A Matched Group Analysis"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7283-4301","authenticated-orcid":false,"given":"Farah","family":"Selman","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Balgrist University Hospital, University of Zurich, 8008 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6010-8847","authenticated-orcid":false,"given":"Philipp","family":"Kriechling","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Balgrist University Hospital, University of Zurich, 8008 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4920-8518","authenticated-orcid":false,"given":"Lukas","family":"Ernstbrunner","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Royal Melbourne Hospital, Parkville, VIC 3050, Australia"},{"name":"Department of Biomedical Engineering, University of Melbourne, Parkville, VIC 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl","family":"Wieser","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Balgrist University Hospital, University of Zurich, 8008 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9780-1300","authenticated-orcid":false,"given":"Paul","family":"Borbas","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Balgrist University Hospital, University of Zurich, 8008 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,1]]},"reference":[{"key":"ref_1","first-page":"27","article-title":"Etude et r\u00e9alisation d\u2019une nouvelle proth\u00e8se d\u2019\u00e9paule","volume":"39","author":"Grammont","year":"1987","journal-title":"Rheumatologie"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1016\/j.jseint.2021.11.002","article-title":"Rate of improvement in shoulder strength after anatomic and reverse total shoulder arthroplasty","volume":"6","author":"Hao","year":"2021","journal-title":"JSES Int."},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Haupt, S., Weber, S., Frima, H., Hutter, R., Grehn, H., and Sommer, C.
