When surgical treatment is chosen, there is sparse evidence on the optimum method. The DelPhi (Delta prosthesis-PHILOS plate) trial is a clinical trial comparing 2 surgical treatments. Our hypothesis was that reverse total shoulder arthroplasty (TSA) yields better clinical results compared with open reduction and internal fixation (ORIF) using an angular stable plate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>The DelPhi trial is a randomized controlled trial comparing reverse TSA with ORIF for displaced proximal humeral fractures (OTA\/AO types 11-B2 and 11-C2) in elderly patients (65 to 85 years of age). The primary outcome measure was the Constant score at a 2-year follow-up. The secondary outcome measures included the Oxford Shoulder Score and radiographic evaluation. Results were reported as the mean difference with 95% confidence interval (CI). The intention-to-treat principle was applied for crossover patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There were 124 patients included in the study. At 2 years, the mean Constant score was 68.0 points (95% CI, 63.7 to 72.4 points) for the reverse TSA group compared with 54.6 points (95% CI, 48.5 to 60.7 points) for the ORIF group, resulting in a significant mean difference of 13.4 points (95% CI, 6.2 to 20.6 points; p &lt; 0.001) in favor of reverse TSA. When stratified for fracture classification, the mean score was 69.3 points (95% CI, 63.9 to 74.7 points) for the reverse TSA group and 50.6 points (95% CI, 41.9 to 59.2 points) for the ORIF group for type-C2 fractures, which yielded a significant mean difference of 18.7 points (95% CI, 9.3 to 28.2 points; p &lt; 0.001). In the type-B2 fracture group, the mean score was 66.2 points (95% CI, 58.6 to 73.8 points) for the reverse TSA group and 58.5 points (95% CI, 49.6 to 67.4 points) for the ORIF group, resulting in a nonsignificant mean difference of 7.6 points (95% CI, \u22123.8 to 19.1 points; p = 0.19).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>At a 2-year follow-up, the data suggested an advantage of reverse TSA over ORIF in the treatment of displaced OTA\/AO type-B2 and C2 proximal humeral fractures in elderly patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level I<\/jats:underline>\n                      .
