The little finger ulnar
palmar digital artery perforator flap: Anatomical basis.
The common palmar digital artery supplying the contiguous side of index and middle fingers passed through the neural loop formed by the proper digital nerve supplying the radial side of the middle finger and joined with the unusually large first palmar metacarpal artery before dividing into proper digital arteries.
The common palmar digital artery of SPA supplying the adjacent sides of the index and middle fingers passed through the neural loop formed by the proper digital nerve of median nerve supplying the radial side of the middle finger and joined with the unusually large first palmar metacarpal artery before dividing into proper digital arteries.
Bataineh and Moqattash reported the absence of the common palmar digital artery to the second web space.
Angiography of equine metacarpus and phalanges: Alterations with medial palmar artery and medial
palmar digital artery ligation.
In addition, a variation was found in the blood supply to the abaxial
palmar digital artery IV and the axial
palmar digital artery V of one seal.
However, in these flaps, the ulnar palmar digital artery is ligated and circulation is supplied retrogradely through the digital artery of the fifth finger.
[8] report that the ulnar palmar digital artery in this location, on the average, ramifies into more than three perforator vessels.
