Finger Infection

Finger Infection Overview

Injury or infection to a finger or fingers is a common problem. Infection can range from mild to potentially serious. Often these infections start out small and are relatively easy to treat. Failure to properly treat these infections can result in permanent disability or loss of the finger.

Early recognition and proper treatment of the following main finger infections will help prevent most of the serious outcomes.

  • Paronychia: A paronychia is an infection of the finger that involves the tissue at the edges of the fingernail. This infection is usually superficial and localized to the soft tissue and skin around the fingernail. This is the most common bacterial infection seen in the hand.
  • Felon: A felon is an infection of the fingertip. This infection is located in the fingertip pad and soft tissue associated with it.
  • Herpetic whitlow: A herpetic whitlow is an infection of the fingertip area caused by a virus. This is the most common viral infection of the hand. This infection is often misdiagnosed as a paronychia or felon.
  • Cellulitis: This is a superficial infection of the skin and underlying tissue. It is usually on the surface and does not involve deeper structures of the hand or finger.
  • Flexor tenosynovitis: This infection involves the tendon sheaths responsible for flexing or closing the hand. This is also a type of deep space infection.
  • Deep space infection: This is an infection of one or several deep structures of the hand or fingers, including the tendons, blood vessels, and muscles. Infection may involve one or more of these structures. A collar button abscess is such an infection when it is located in the web space of the fingers.
