Patients were categorized into two groups, namely displaced and nondisplaced, based on radiographic outcomes. Factors affecting fracture re\u2010displacement were examined, including sex, age, side, AO\/OTA type, external fixation, and radiographic outcomes at pre\u2010reduction and immediate reduction. Logistic regression analysis was employed to identify the risk factors for fracture re\u2010displacement, and ROC curves were constructed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the 884 patients, 563 (63.69%) experienced re\u2010displacement after fracture reduction.
