Treatment of cold intolerance following finger pulp amputations: a case comparison between immediate finger replantation and delayed pulp and digital arterial arch reconstruction with flow-through free hypothenar flap.

We report a unique case of cold intolerance following identical fingertip amputations of two fingers on the same hand. The index finger was replanted and the middle finger was reconstructed with a free flow-through hypothenar perforator flap to anatomically restore the digital arterial arch circulation and successfully treat cold intolerance.
