HIGH RESOLUTION ULTRASOUND OF FASCICLES IN THE ULNAR AND MEDIAN NERVES

Mohamed A. Bedewi, MD*

ABSTRACT

Background: The objective of this work is to study the nerve fascicles of the ulnar and median nerves at two predetermined sites bilaterally. Methods: Twenty seven healthy volunteers underwent imaging of the median nerve and ulnar nerves at the wrist and the forearm bilaterally. Results: The mean fascicular number of the median and ulnar nerves were estimated (two sites for each nerve). Demographic factors did not correlate positively with the fascicular number. Cross sectional area correlated positively with the fascicular number at four sites. Conclusions: The results of this study could be used in the diagnosis of different diseases involving the nerve fascicles, especially Charcot-Marie Tooth.

Keywords: Ultrasound, median nerve, ulnar nerve, fascicles.
