Palmar Ulnar Artery Perforator Free Flap for Fingertip Reconstruction: Anatomical and Clinical Study

Figure 1

Palmar ulnar artery perforator (PAUP) arising location based on , coordinates on the hand. We evaluated the following parameters: the distance from the line between the pisiform and hamate bones set up as -axis to the point at which the perforators emerge; the diameter of the artery at the origin; and the length of the pedicle from the origin to the bifurcation.
