Tomita Y, Yamamoto N, Inoue T, et al. - This study was sought to examine the discriminative accuracy of a clinical prediction model for ambulatory ability outcomes 3 months after surgery for trochanteric fractures. Researchers conducted a retrospective cohort study including a total of 346 patients treated with intramedullary nailing for trochanteric fractures who had the independent ambulatory ability before their injury. They used multiple regression models with preoperative and postoperative factors to prognosticate ambulatory ability outcomes at 3 months. A clinical prediction model with moderate accuracy was developed to predict ambulatory ability outcomes in patients 3 months after surgery for trochanteric fractures. The findings indicate the importance of the BI score measured soon after surgery and dementia status for the prediction of postoperative ambulation.
