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

TL;DR

This study examines the anatomy of the radius bone to better understand its structure and implications for surgical treatments.

Contribution

The study provides new osteometric correlations between the dorsal radial tubercle and neighboring anatomical elements.

Findings

The length of the radius correlates positively with the width of the distal epiphysis.

The distance from the suprastyloid crest to the dorsal radial tubercle is strongly associated with the development of the distal radial epiphysis.

Distances between the dorsal radial tubercle and other anatomical ridges correlate with the distal epiphysis width.

Abstract

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.
