    The study investigates the link between triglyceride glucose–body mass index (TyG–BMI) and nonunion rates in elderly patients post-limb fracture surgery.

  • 2

    A total of 8,499 patients were analyzed, with 141 cases (1.66%) developing nonunion after surgery.

  • 3

    A U-shaped relationship was found between TyG–BMI levels and nonunion risk, with both low and high levels increasing the risk.

  • 4

    TyG–BMI levels below 173.9 and above 213.0 were independently associated with increased nonunion risk.

  • 5

    The findings suggest TyG–BMI could serve as a predictive biomarker for nonunion risk stratification in older fracture patients.
