“…The literature regarding the arterial anatomy of the dorsal aspect of the hand was reviewed and some divergences concerning the presence and the constancy of DMAs and their relationships with the palmar arterial system were observed 9,[17][18][19][20][21][22] . According to previous studies 26,27 , the radial artery divides into 3 branches at the level of the anatomic snuffbox: the princeps pollicis artery, the 1DMA, and the branch to the deep palmar arch.…”

Anatomic study of the dorsal arterial system of the hand

Historically, the dorsal arterial system of the hand received less attention than the palmar system. The studies concerning dorsal arterial anatomy present some controversies regarding the origin and presence of the dorsal metacarpal artery branches. Knowledge of the anatomy of dorsal metacarpal arteries is especially applied in the surgical planning for flaps taken from the dorsum of the hand. The purpose of this study is to analyze the arterial anatomy of the dorsum of the hand, compare our observations with those of previous studies from the literature, and therefore to define parameters for surgical planning for flaps supplied by the dorsal metacarpal arteries.METHOD: Twenty-six dissections were performed at the dorsum of the right hand of 26 cadavers by making a distalbased U-shaped incision. After catheterization of the radial artery at the wrist level, a plastic dye solution with low viscosity and quick solidification was injected to allow adequate exposure of even small vessels. The radial artery and its branches, the dorsal arterial arch, the dorsal metacarpal arteries, the distal and proximal communicating branches of the palmar system, and the distal cutaneous branches were carefully dissected and identified. RESULTS:The distal cutaneous branches originating from the dorsal metacarpal arteries were observed in all cases; these were located an average of 1.2 cm proximal from the metacarpophalangeal joint. The first dorsal metacarpal artery presented in 3 different patterns regarding its course: fascial, subfascial, and mixed. The branching pattern of the radial artery at the first intermetacarpal space was its division into 3 branches. We observed the presence of the dorsal arterial arch arising from the radial artery in 100% of the cases. The distance between the dorsal arterial arch and the branching point of the radial artery was an average of 2 cm. The first and second dorsal metacarpal arteries were visualized in all cases. The third and fourth dorsal metacarpal arteries were visualized in 96.2% and 92.3% of cases, respectively. There was proximal and distal communication between the dorsal arterial arch and the palmar system through the communicating branches contributing to the dorsal metacarpal artery formation.CONCLUSION: At the dorsum of the hand there is a rich arterial net that anastomoses with the palmar arterial system. This anatomical characteristic allows the utilization of the dorsal aspect of the hand as potential donor site for cutaneous flaps.

This study describes the anatomy of the dorsal cutaneous vascular system of 180 digits (36 thumbs, index, middle, ring, and little fingers) from 18 pairs of fresh human cadaver hands. The aim of this paper is to incorporate the anatomic data into the current way of designing the homodigital adipofascial turnover flap for cutaneous coverage of the dorsum of the finger. We have carried out an anatomic study in preserved cadaver hands to define the distance between the joint and the origin of the dorsal cutaneous branches of the proper palmar digital artery in the proximal and middle phalanx of the long fingers and for the thumb to metacarpal and interphalangeal joint. All branches of the proper digital artery that ran to the dorsal skin were then identified, and their diameters and the distances of their origins from the proximal interphalangeal joint were measured. We showed that 2 constant branches in the proximal and middle phalanx from each proper digital artery have consistent sites of origin at predictable distances from the proximal interphalangeal joint for the long fingers and the metacarpal and interphalangeal joint for the thumb. The flap survival was excellent, and no donor site complications were observed. We showed that these branches have consistent sites of origin at predictable distances from the proximal interphalangeal joint. The adipofascial turnover arterial flap has appeared as an excellent alternative to achieve early coverage of cutaneous wounds at the dorsal aspect of the fingers.

“…From several studies on the anatomy of the first interosseous artery, it appears that: • The first dorsal interosseous artery just above the aponeurosis is frequent but variable [1][2][3]. • The first dorsal interosseous artery gives several branches to supply the skin of the first web [1,8].…”
