Morphological Study of Nutrient Foramen of Left Human Clavicle in Male and Female
Journal Title: Journal of Clinical Medical Research - Year 2025, Vol 6, Issue 1
Abstract
Background: The clavicle demonstrates significant morphological variations between males and females, making it valuable for sex determination in forensic investigations. The nutrient foramen’s location and characteristics are crucial for surgical procedures, yet comprehensive morphometric data specific to certain populations remains limited. Objectives: This study aimed to analyze the morphological variations in left clavicles, focusing on sexual dimorphism and nutrient foramen characteristics, to establish population-specific morphometric standards and enhance surgical and forensic applications. Methods: A cross-sectional analytical study was conducted on 120 dry ossified left human clavicles (70 male, 50 female) using standardized measurement techniques. Measurements included basic morphometric parameters, angular measurements, curvature characteristics and nutrient foramen features. Data were analyzed using Student’s t-test, with statistical significance set at p≤0.05. Results: Significant sexual dimorphism was observed in most parameters. Male clavicles showed greater mean length (136.83 ± 6.79 mm vs 128.36 ± 4.43 mm), midclavicular circumference (36.80 ± 1.60 mm vs 34.35 ± 1.89 mm) and weight (16.45 ± 2.76 g vs 12.86 ± 1.94 g) compared to females (p<0.001). Single nutrient foramina predominated in both sexes (92.86% males, 86% females), typically located on the posterior surface (90% males, 88% females) in the middle third of the clavicle (93% males, 92% females). While most parameters showed significant sexual differences, the robustness index and some articular surface measurements demonstrated no significant variation between sexes. Conclusion: This study establishes comprehensive morphometric standards for the studied population, demonstrating significant sexual dimorphism in most parameters and consistent patterns in nutrient foramen characteristics. These findings provide valuable reference data for surgical procedures, forensic investigations and anthropological studies, while highlighting the importance of population-specific morphometric standards.
