Anatomic dissections for this study were performed on formalin fixed 48 cadaveric hands, 24 left sides and 24 right sides. The communicating branches between the median and ulnar nerves in the palm were determined as five types. The relationship between these two nerves was classified as six different types according to the types, the numbers and the absence of the communicating branches. Type a: The communicating branch from the palmar branch of the common digital nerve (ulnar nerve) to the common digital nerve (median nerve) Type b: Multiple communicating branches Type c: The communicating branch from the bifurcation point of the superficial ramus of the ulnar nerve to the palmar branch of the common digital nerve (median nerve) Type d: Absence of the communicating branch Type e: The communicating branch from the palmar branch of the common digital nerve (median nerve) to the common digital nerve (ulnar nerve) Type f: The communicating branch between the palmar branch of the common digital nerve and the palmar branch of the common digital nerve (ulnar nerve) Type a was observed in 15 (% 31.25), type b in 2 (% 4.17), type c in 5 (% 10.42), type d in 24 (% 50), type e in 1 (% 2.08) and type f in 1 (% 2.08) of our samples according to this classification. We consider that to be aware of these variations will be usefull for the assessment of nerve injuries and hand surgery.
