Apr 12, 2005 · The 3 nerves involved in dorsal hand sensory innervation are the superficial branch of the radial nerve (SBRN), the dorsal branch of the ulnar nerve (DBUN), and the lateral antebrachial cutaneous nerve (LABCN). Few studies have examined the detailed anatomy of the SBRN in the past several decades.

Medial dorsal cutaneous nerve - Wikipedia
The medial dorsal cutaneous nerve (internal dorsal cutaneous branch) is the more medial one of the two terminal branches of the superficial fibular nerve (the other being the intermediate dorsal cutaneous nerve). Through its branches, it provides innervation to parts of the dorsal aspects of the first, second, and third toes. [1]
The Cutaneous Innervation of the Dorsal Hand: Detailed …
In the course of our research aimed at providing surgeons with a detailed anatomic map of cutaneous nerves in the dorsal hand, we came across the article by Mok et al (J Hand Surg 2006;31A:565–574.).
Anatomic Relationships and Branching Patterns of the Dorsal Cutaneous ...
To describe the variable branching patterns of the dorsal cutaneous branch of the ulnar nerve (DCBUN) relative to identifiable anatomic landmarks on the ulnar side of the wrist. We dissected the ulnar nerve in 28 unmatched fresh-frozen cadavers to identify the DCBUN and its branches from its origin to the level of the metacarpophalangeal joints.
