Abstract:
The ulnar vessels of 50 adult cadavers were studied under operating microscope to investigate the vascular basis of an ulnar skin flap in the forearm. The length of the stem of the ulnar artery is 21.63 cm in average. The length of the covered and exposed segments is 10.79 and 10.88 cm respectively. The caliber of the ulnar artery is 3.90, 2.70 and 2.30 mm at its upper, middle and lower parts respectively. Each ulnar artery gives off 7.86 cutaneous branches in average. The number of the cutaneous branches of the covered segment is smaller than that of the exposed segment, but the caliber of the branches of the former is larger. These cutaneous branches cover an area of 79.57 cm2, mainly medial to the line from the mid-point of the medial supracondylar line to the mid-point of the interstyloid line. A large cutaneous branch arises from the covered segment with relatively constant origin, course and distribution. The caliber of this branch is 1.01 mm and its distribution area 19.57 cm2 in average. This branch may be used asa solitary arterial pedicle for a skin flap. Certain problems in relation to the transplantation of a free ulnar skin flap in the forearm were discussed.
