Abstract :Aim: The radius, located on the lateral forearm, plays a key role in pronation and supination. Its proximal and distal ends contribute to the stability and motion of the elbow and wrist joints, making them susceptible to trauma, with fractures common, especially in the geriatric population. Understanding the morphological and morphometric features of these ends is crucial for surgical interventions, such as screwing techniques for complex fractures. This study aims to examine the morphological and morphometric characteristics of the proximal and distal ends of the human radius and provide clinically relevant data. Material and Method: 70 radii (34 right and 36 left) from the collections of Necmettin Erbakan University and Acıbadem Mehmet Ali Aydınlar University were analyzed. Measurements were taken using digital calipers, an osteometric board, a tape measure, and the Image J program. Morphological classifications of the articular fovea and radial tuberosity were recorded. Morphometric analysis of the proximal and distal extremities was conducted, and data, analyzed using SPSS 21, were found to be normally distributed. Right-left comparisons were made using paired Student\\\'s t-tests, type differences with one-way ANOVA, and relationships with correlation tests. Results: Among all radii, 97.1% of articular foveae were elliptical, while 54.3% of radial tuberosities were single roughened (Type b). No significant differences were found in the morphology of the articular fovea or radial tuberosity between the right and left sides (p>0.05). The medial thickness of the radial head (RH-mt) and the anterior lenght of the ulnar notch (UN-al) were significantly larger on the right side (p<0.05). Larger circumferences, diameters, and inclination angles were observed in double roughened (Type c) radial tuberosities (p<0.05). This was observed for the medial and lateral sides, as well as for the neck and head regions. Conclusion: The data obtained from our study might be useful as a reference in post-traumatic reconstruction, prosthesis design and orthopaedic surgical procedures in adults.
