Osteometric Study of the Dorsal (Lister's) Tubercle of the Radius in Relation to the Neighboring Anatomical Elements: Suprastyloid, Accessory, and Oblique Crests.

Background: The radius, a crucial bone in the human forearm, supports and facilitates complex movements like pronation and supination. Its anatomical landmarks, including Lister's tubercle, provide vital attachment points for muscles, tendons, and ligaments involved in upper limb mobility. This study provides a detailed osteometric analysis of the dorsal radial tubercle of the radius, aiming to improve our understanding of its anatomy and clinical significance. Material and Methods: The study was conducted in the Department of Anatomy and Embryology, using 56 radius bones from cadavers. After applying inclusion and exclusion criteria, 46 bones remained in the study group. Results: The study found a significant positive correlation between the length of the radius and the width of the distal epiphysis. The distance from the suprastyloid crest to the dorsal radial tubercle (SC-DT) and the distal epiphysis width were strongly associated with the development of the distal radial epiphysis. The distance between the dorsal radial tubercle and the oblique ridge (OR-RI) and between the oblique ridge and the radial incisure (DT-OR) also showed a strong positive correlation with the distal epiphysis width. Conclusions: In conclusion, the osteometric study performed reveals significant correlations between the bony elements of distal radius epiphysis that can provide valuable information regarding anatomic variability and surgical treatment of distal radial epiphyseal fractures.
