Ultrasound Study of Radial Nerve Projective Anatomy Relative to Lateral Humerus Aspect

Location of radial nerve relative to lateral humerus was studied using US scanner in 17 volunteers (7 men, 10 women) aged 19-54 years. Conditional humerus length (acromion-olecranon distance) ranged from 31 to 39 cm. Radial nerve transacted lateral humeral diaphysis 11.3±1.9 cm (from 8 to 15 cm) proximal to lateral humeral epicondyle. Distance between lateral humeral epicondyle to radial nerve made up 31.9% of humerus conditional length. Awareness of obtained data may be helpful at performance of surgical intervention on the humerus.
