Fingertip Infections.

Abstract

The fingertip is the most common site of infections in the hand, which frequently are encountered by surgeons, dermatologists, and emergency and primary providers. Their mismanagement may have serious consequences. This review discusses the unique anatomy of the volar fingertip pulp and perionychium and reviews pathophysiology and treatment of acute and chronic paronychia, including the decision for surgical versus medical management, choice of antibiotics, incisional techniques, and postincisional care. Felons and the evidence regarding their management are reviewed. Several infectious, rheumatologic, and oncologic conditions that may mimic common fingertip infections and about which the managing provider must be aware are presented.
