Background: Vitamin D deficiency has emerged as a significant factor affecting bone healing and postoperative recovery in orthopedic patients. Lower limb fractures represent a substantial burden on healthcare systems, with recovery outcomes varying significantly among patients.
Objective: This study aimed to evaluate the role of vitamin D levels in postoperative recovery outcomes among patients with lower limb fractures, including healing time, complications, and functional restoration.
Methods: A prospective cohort study was conducted involving 180 patients with lower limb fractures requiring surgical intervention. Patients were categorized based on preoperative vitamin D levels: deficient (<20 ng/mL), insufficient (20-30 ng/mL), and sufficient (>30 ng/mL). Primary outcomes included radiographic union time, postoperative complications, and functional scores at 3, 6, and 12 months.
Results: Patients with vitamin D deficiency demonstrated significantly prolonged healing times (14.2 ± 3.8 weeks vs. 10.1 ± 2.4 weeks, p<0.001), higher complication rates (32% vs. 12%, p<0.01), and inferior functional outcomes compared to those with sufficient levels. Vitamin D supplementation in deficient patients improved recovery parameters significantly.
Conclusion: Adequate vitamin D levels are crucial for optimal postoperative recovery in lower limb fracture patients. Routine screening and supplementation should be considered as standard care protocols.
