Three transmetacarpal injuries are described in which the patency of one common digital vessel alone provided blood flow to all fingers. Transverse commissural vessels connect the digital vessels proximal to the proximal and distal interphalangeal joints. Retrograde flow to the adjacent common digital vessels revascularises the other digits. The volar metacarpal vessels, if not ligated, may allow continued bleeding into the palm following reattachment of a transmetacarpal amputation. These vessels may have been responsible for failure of the replantation in one case.
