Abstract
To devise a new classification of vascular variations in second toe transfer we analyzed
the anatomic details of the first dorsal metatarsal artery in 304 cases of second
toe transplantation and the venous structure in 200 cases. According to location,
the arterial vascularity was classified as superficial (18% of cases), intramuscular
(54%), inframuscular (23%), and absent (5%). According to diameter, it was classified
into large (16%), medium (64%), and small (20%). Based on branching pattern, the artery
was classified into ramifying type (88%), main trunk (4%), and fine branch type (8%).
The venous drainage of the second toe was categorized as greater saphenous vein main
trunk type, greater saphenous vein fine branch type, dorsal digital vein main trunk
type, and dorsal digital vein fine branch type. Variations of the first dorsal metatarsal
artery are common. Classification should be done according to its location, diameter,
and branching pattern at the toe web. Regardless of location, big vessels entering
the second toe are the most important attribute for successful outcome. (J Hand Surg
