Abstract
Objective: The lateral arm flap remains a popular flap, especially as a free flap. In this article, the authors describe the perforator anatomy to optimize flap design and harvest. Subject and method: The study was carried out on 20 upper arms of 10 fresh Vietnamese cadavers. The cutaneous perforators were dissected and mapped. Result: The flap was based on the lateral intermuscular septum and supplied from cutaneous perforators of the posterior radial collateral artery (PRCA). The average pedicle length was 5.81 ± 0.96cm. 75% of specimens were constant three perforators while the remaining 25% were four perforators. The distances from the groove to perforators were 5.81 ± 0.96cm, 7.97 ± 0.78cm, 10.09 ± 0.70cm and 12.15 ± 0.77cm respectively, and from the lateral epicondyle were 10.51 ± 0.88cm, 8.25 ± 0.73cm, 6.11 ± 0.77cm and 4.32 ± 0.67cm. The mean diameter of 3 large perforators were 0.66 ± 0.06mm, 0.59 ± 0.03mm and 0.4 ± 0.03mm. The cadavers were almost symmetric in the number and location of the perforators between the right and left arms. Conclusion: The lateral arm flap can be safe to design and can be harvested reliably based on constant perforators and anatomical landmarks.
