Development and validation of a cut-off chart for predicting postoperative liver dysfunction following PFNA fixation: composite endpoint and Boruta-based analysis

A novel nomogram for predicting PLD in ITF patients after PFNA was successfully developed and internally validated. Using easily accessible clinical variables, this tool enables accurate early risk stratification, helping clinicians identify high-risk patients and optimize peri-operative care. It highlights the importance of inflammatory, coagulation, and fracture-related factors in PLD prediction for this cohort.
