Link Between Triglyceride Glucose–Body Mass Index and Nonunion Rates in Elderly Patients

Overview

This study investigates the relationship between triglyceride glucose–body mass index (TyG–BMI) and nonunion rates in elderly patients post-limb fracture surgery. Findings indicate that both low and high TyG–BMI levels are associated with increased nonunion risk, highlighting its potential as a predictive biomarker for this population.

Background

Nonunion is a significant complication following orthopedic surgery, particularly in older patients, leading to increased healthcare costs and prolonged rehabilitation. Metabolic syndrome is emerging as a critical risk factor for impaired fracture healing, necessitating the identification of reliable biomarkers for early intervention. The TyG-BMI index offers a simple, cost-effective means to assess metabolic dysfunction and its impact on fracture healing.

Data Highlights

Key Findings

• 141 out of 8,499 patients developed nonunion (1.66%).
• U-shaped relationship between TyG-BMI and nonunion risk identified.
• Low TyG-BMI (<173.9) associated with increased nonunion risk (aOR 1.358).
• High TyG-BMI (>213.0) also linked to increased nonunion risk (aOR 1.233).
• Significant interactions noted between TyG-BMI levels and perioperative blood transfusion and bone grafting type.

Clinical Implications

Clinicians should consider TyG-BMI as a potential biomarker for assessing nonunion risk in elderly patients undergoing limb fracture surgery. Early identification of patients with low or high TyG-BMI may guide individualized management strategies to improve surgical outcomes.

Conclusion

The study underscores the importance of metabolic assessment in predicting nonunion risk in older patients post-surgery. TyG-BMI may serve as a valuable tool for risk stratification and tailored interventions.
