This study evaluated the sonoanatomy of the deep motor branch of the ulnar nerve (DBUN) using high-resolution ultrasonography (HRUS).



ultrasonography
This study evaluated the sonoanatomy of the deep motor branch of the ulnar nerve (DBUN) using high-resolution ultrasonography (HRUS).


 In 60 wrists of 30 healthy adults, the gross course, cross-sectional area (CSA), and diameter of the DBUN were observed by HRUS (frequency band 3-16 MHz).  The DBUN was found in all subjects with HRUS, and it branched off from the ulnar nerve before reaching the hamate bone.  Sonoanatomy of the DBUN obtained from HRUS may be useful in detecting or preventing DBUN lesions.
