Latissimus dorsi tendon transfer (LDTT) is a therapeutic alternative suitable for the treatment of rotator cuff tears that helps to restore external shoulder rotation. Cadaver models have been used for studying the effects of LDTT and procedural variations, but, to the best of our knowledge, none of them have been validated. The aim of our study was to validate a novel cadaver model while verifying the effects of LDTT on external rotation. Materials and Methods: Two groups were included in the study: a cadaver group and a control group made up of healthy volunteers, which were used for the validation of the cadaver model. Baseline external rotation measurements were performed with both groups, after which a massive rotator cuff tear was inflicted and repaired with LDTT in the cadaver group. Their postoperative external rotation was evaluated using three different tests. Results: No statistically significant differences were found between the baseline measurements of the two groups, and postoperative external rotation was significantly higher after LDTT in all cases but one. Conclusions: Cadaver models were validated, since they had a similar preoperative external rotation to healthy volunteers. Moreover, they allowed us to demonstrate the effect of LDTT on external shoulder rotation.<\/jats:p>","DOI":"10.3390\/medicina57040305","type":"journal-article","created":{"date-parts":[[2021,3,24]],"date-time":"2021-03-24T15:42:19Z","timestamp":1616600539000},"page":"305","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Enhancement of External Rotation after Latissimus Dorsi Tendon Transfer (LDTT): A Cadaveric Study"],"prefix":"10.3390","volume":"57","author":[{"given":"Jos\u00e9 M.","family":"Silberberg","sequence":"first","affiliation":[{"name":"Orthopaedic Surgery and Traumatology Head Department, Sports Medicine Unit, Cl\u00ednica Universidad de Navarra, 28027 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Nilo","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery and Traumatology Department, Chief of Upper Limb Unit, Hospital General Regional N1, 97155 M\u00e9rida, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8405-8976","authenticated-orcid":false,"given":"Jorge","family":"Roces-Garc\u00eda","sequence":"additional","affiliation":[{"name":"Department of Construction and Manufacturing Engineering, Polytechnic School of Engineering of Gij\u00f3n, University of Oviedo, Pedro Puig Adam s\/n, ED06, 33203 Gij\u00f3n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,24]]},"reference":[{"key":"ref_1","first-page":"27","article-title":"A review of biomechanics of the shoulder and biomechanical concepts of rotator cuff repair","volume":"2","author":"Yamamoto","year":"2015","journal-title":"Asia-Pac.
