Abstract:

Objective To study the applied anatomical basis of using the posterolateral forearm free perforator flap to repair soft tissue defects in the finger. Methods Forty upper limb specimens were dissected. The origin, distribution and anastomosis of the vessels, nerves in the posterior-lateral forearm were observed with regional anatomy using surgical magnifying glass. Results At the midpoint of line from the radial Lister nodule and the humeral condyle , between the septum of extensor digitorum muscle and extensor carpi radialis muscle, there was an intermuscular septum cutaneous perforator constantly present with two accompanying veins. The posterior antebrachial cutaneous nerve innervated this area.  The length of perforator artery pedicle is (4.12±0.26)cm,and the diameter was (0.91±0.07)mm at the origin, which was similar to the digital artery. Conclusion The posterior-lateral forearm can be applied as a free perforator flap pedicled by the intermuscular septum cutaneous perforator artery to repair soft tissue defects in the finger.
