Patients were divided into two groups: those who underwent plate osteosynthesis (PO) and those managed non-surgically (NO). Functional outcomes, including range of motion, strength, and patient-reported quality of life were evaluated using standardized assessments such as the Constant-Murley score and Short-Form-36 (SF-36) questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 241 patients (161 in the Surgical Group and 80 in the Non-Operative Group) were included in the study. With a mean follow-up of 10.4\u2009\u00b1\u20093.1\u00a0years, both groups demonstrated comparable functional outcomes. The Constant-Murley score in the Surgical Group was 53.5\u2009\u00b1\u200921.8 compared to 60.1\u2009\u00b1\u200924.2 in the Non-Operative Group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.225). Complication rates were significantly higher in the PO group. The revision rate for patients treated with plate osteosynthesis was 37.9%.
