The development of new osteosynthesis materials is being driven by the high complication rates following surgical treatment of proximal humerus fractures. Plate osteosyntheses made of steel, titanium and, for several years now, carbon fiber-reinforced polyetheretherketone (CFR-PEEK) are used most frequently. Methods: A prospective, randomized study was conducted in order to evaluate whether there are differences in the functional postoperative outcome when comparing CFR-PEEK and titanium implants for surgical treatment of proximal humerus fractures. The primary outcome of shoulder functionality 1 year after surgery was measured with the DASH score, the Oxford Shoulder Score, and the Simple Shoulder Test. Results: Bony consolidation of the respective fracture was confirmed in all the patients included in the study within the scope of postoperative follow-up care. No significant differences in the DASH score, Oxford Shoulder Score, or Simple Shoulder Test were observed 1 year post-operatively when comparing the implant materials CFR-PEEK and titanium. Conclusions: There are no differences in terms of the functional outcome between CFR-PEEK plates and titanium implants 1 year after surgery. Studies on the long-term outcomes using CFR-PEEK plates in osteoporotic bone should be the subject of further research.<\/jats:p>","DOI":"10.3390\/jcm12216881","type":"journal-article","created":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T12:53:32Z","timestamp":1698756812000},"page":"6881","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Clinical Outcome of Carbon Fiber Reinforced Polyetheretherketone Plates in Patients with Proximal Humeral Fracture: One-Year Follow-Up"],"prefix":"10.3390","volume":"12","author":[{"given":"Patrick","family":"Ziegler","sequence":"first","affiliation":[{"name":"Department of Trauma and Reconstructive Surgery, Klinik Gut, 7500 St. Moritz, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sven","family":"Maier","sequence":"additional","affiliation":[{"name":"Department of Trauma and Reconstructive Surgery, BG Unfallklinik Tuebingen, Eberhard Karls University Tuebingen, Schnarrenbergstrasse 95, 72076 Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabian","family":"Stuby","sequence":"additional","affiliation":[{"name":"BG Trauma Center, Department for Traumatology, Orthopedics and Surgery, 82418 Murnau am Staffelsee, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tina","family":"Histing","sequence":"additional","affiliation":[{"name":"Department of Trauma and Reconstructive Surgery, BG Unfallklinik Tuebingen, Eberhard Karls University Tuebingen, Schnarrenbergstrasse 95, 72076 Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"Ihle","sequence":"additional","affiliation":[{"name":"Department of Trauma and Reconstructive Surgery, BG Unfallklinik Tuebingen, Eberhard Karls University Tuebingen, Schnarrenbergstrasse 95, 72076 Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrich","family":"St\u00f6ckle","sequence":"additional","affiliation":[{"name":"Center for Musculoskeletal Surgery, Charit\u00e9 University Medicine Berlin, 10117 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"G\u00fchring","sequence":"additional","affiliation":[{"name":"Kronprinzenbau Klinik, 72764 Reutlingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"612","DOI":"10.1097\/00001648-199611000-00008","article-title":"Basic epidemiology of fractures of the upper and lower limb among Americans over 65 years of age","volume":"7","author":"Baron","year":"1996","journal-title":"Epidemiology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"121","DOI":"10.2106\/JBJS.I.01505","article-title":"Trends and variation in incidence, surgical treatment, and repeat surgery of proximal humeral fractures in the elderly","volume":"93","author":"Bell","year":"2011","journal-title":"J.
