A New Perforator Flap From Distal Medial Arm: A Cadaveric Study

Background: In this study, a new fasciocutaneous perforator flap raised from inner medial surface of the distal medial arm has been described for soft tissue coverage. Methods: The blood supply of this flap comes directly from the distal brachial artery. Fourteen limbs of 7 formalinized cadavers were dissected to study the origin and the course of perforator vessel. Results: The average size of the flap was 10.7 cm × 5.6 cm in the distal medial arm region. The constant main perforator was measured within a circle of 2.76-cm diameter, the center of which was 11.5 cm above and 1.3 cm medial to the medial epicondyle of humerus. The mean length and diameter of the distal brachial perforator artery were 3.3 cm and 0.95 mm, respectively. Conclusion: We think that this flap may be a useful option for the reconstruction of soft tissue defect of elbow.
