[Anatomy study of MGA in Chinese and its effect on legal expertise].
OBJECTIVE
This study aimed to clarify the morphology of the Martin-Gruber anastomosis (MGA) in Chinese.


METHODS
One hundred and five Chinese upper limbs (36 males and 20 femalese) were dissected to find the connections between medial nerve and ulnar nerve. The MGA was classified as previously described by Lee.


RESULTS
MGA was found in 24 cases (22.9%), in 11 of the 36 male and 5 of the 20 female. There was no obvious difference in the frequency of MGA in both upper limbs. Most MGA ulnar position was located at the medial and distal segment of the forearm.


CONCLUSIONS
MGA anatomy could play important role in forensic diagnosis of ulnar nerve injury in Chinese population.
