    Context: The fibula serves crucial functions in lower limb biomechanics and is frequently used in reconstructive surgery. Understanding its nutrient foraminal patterns is essential for surgical success and forensic applications. However, population-specific data for Bangladeshi fibulae has been lacking. Objectives: To determine the morphometric characteristics of diaphyseal nutrient foramina in dried Bangladeshi fibulae. Methods: This cross-sectional analytical study examined 120 dry fully ossified left human fibulae (68 male, 52 female) at Dhaka Medical College. Measurements included total length, diaphyseal dimensions, nutrient foraminal characteristics (number, position, direction), and talar facet parameters. Sexual dimorphism was assessed using unpaired Student's t-test and chi-square test. Results: Significant sexual dimorphism was observed in total length (male: 35.41 ± 1.67 cm, female: 32.72 ± 1.28 cm, p<0.001), midshaft diameter (male: 14.01 ± 1.07 mm, female: 13.21 ± 0.85 mm, p<0.001), and nutrient foraminal measurements. Single nutrient foramen predominated in both sexes (male: 95.6%, female: 92.3%), with primarily downward direction (male: 95.6%, female: 100%). Type-2 Foraminal Index was most common (male: 98.5%, female: 98.1%). Nutrient foramina were predominantly located on the posterior surface in males (42.6%) and medial crest in females (32.7%). Conclusion: This study establishes baseline morphometric data for Bangladeshi fibulae, demonstrating significant sexual dimorphism and consistent nutrient foraminal patterns. These findings have immediate applications in surgical planning, particularly for fibular grafting procedures, and provide valuable reference data for forensic sex determination in the Bangladeshi population.
