[Applied anatomy of the sensate latissimus dorsal muscular flap with the lateral posterior branch of the intercostal nerve].
OBJECTIVE
To provide anatomy basis for a free latissimus dorsal muscular flap with the sensate nerve.


METHODS
The structure of back and lateral chest area were dissected and the origin, alignment and distribution of the intercostals nerve within the area of latissimus dorsal muscular flap were observed in 40 adult cadaver specimens.


RESULTS
The 5th to 10th lateral posterior branches of the thoracic nerve pierced from respective intercostal area near the axial anterior line and run a long distance in deep fascia. They distributed mainly in lateral latissimus skin outside the scapular line and anastomosed with the lower branch near the scapular line. Among these branchs, the 6th to 8th branches had a longer nerve distribution respectively and the pedicle of nerve and artery was parallel and long.


CONCLUSIONS
It is possible to design a sensate latissimus dorsal muscular flap with the 6th to 8th lateral posterior branch of the intercostal nerve.
