Aim: To analyze the morphology and morphometry of the proximal end of dry radii in the Indian population and provide insights into anatomical variations relevant to clinical and anthropological applications. Material and Methods:This cross-sectional, observational study included 120 dry radii (60 right and 60 left) obtained from osteology collections in Indian medical colleges. Morphological features, including radial head shape, neck orientation, and tuberosity characteristics, were documented. Morphometric parameters, such as diameters of the radial head and neck, tuberosity dimensions, and angle of inclination, were measured using a digital vernier caliper. Descriptive and inferential statistical analyses were performed using SPSS. Results:The radial head was predominantly circular (65.00%), with oval (30.00%) and irregular shapes (5.00%) observed less frequently. Straight neck orientation was most common (50.00%), followed by slightly angled (40.00%) and angled (10.00%) orientations. The mean transverse diameter of the radial head was 21.5 ± 2.3 mm, and the mean anteroposterior diameter was 20.2 ± 2.1 mm, with no significant differences between the right and left sides (p=0.356, p=0.412). The radial neck’s transverse and anteroposterior diameters measured 12.5 ± 1.8 mm and 11.8 ± 1.7 mm, respectively. Radial tuberosity dimensions (mean length: 13.2 ± 1.5 mm; mean width: 10.8 ± 1.4 mm) and the angle of inclination (12.5 ± 2.2 degrees) showed bilateral symmetry without significant differences (p>0.05). Conclusion:The study highlights the predominance of circular radial heads and bilateral symmetry in morphometric parameters in the Indian population. These findings enhance our understanding of population-specific anatomical variations, which are essential for improving surgical approaches, implant designs, and anthropological research. |
