Forearm flap resection

Forearm radial skin flaps are generally taken. The flaps include radial arteries, veins, cephalic veins, lateral cutaneous nerves of the forearm and superficial radial nerve branches, and the latter are mostly retained in the forearm. The radial projection line is from the midpoint of the humerus internal and external intercondylar border line to the wrist radial radial styloid medial pulsation. The flap is designed as the central axis, and the upper end can reach the lower third of the upper arm and the lower end It can reach the transverse carpal ligament, and the width of both sides can reach 3/4 of the circumference of the forearm [Figure 1]. The forearm flap has a constant blood vessel running, a thin thickness, and a large donor area. It is especially suitable for the repair of facial and hand wounds. However, because the forearm is an exposed part, there are still ugly marks after suture or skin grafting. This valve is forbidden when the ulnar artery has poor blood supply.
