Finger Infection

Finger Infection Overview

Injury or infection to a finger or fingers is a mutual 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 post-obit principal 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 manus.
• 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 acquired by a virus. This is the about common viral infection of the hand. This infection is often misdiagnosed equally a paronychia or felon.
• Cellulitis: This is a superficial infection of the peel and underlying tissue. Information technology is ordinarily on the surface and does not involve deeper structures of the hand or finger.
• Infectious flexor tenosynovitis: This infection involves the tendon sheaths responsible for flexing or endmost the hand. This is also a blazon 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, claret vessels, and muscles. Infection may involve one or more of these structures. A neckband button abscess is such an infection when it is located in the web infinite of the fingers.

Finger Infection Causes

Bacteria cause most of these finger infections. The exception to this is the herpetic whitlow, which is caused by a virus. How the infection starts and is establish in a particular location is what makes each specific type of infection unique. Usually some form of trauma is the initial upshot. This may be a cut, creature bite, or puncture wound.

• Paronychia: The offending leaner are ordinarily staphylococcal and streptococcal organisms. Rarely, a fungus causes this infection, which usually begins as a hangnail. Often a person will attempt to bite off the piece of nail that is at the corner. This results in an open wound that allows the bacteria institute on the peel and the leaner found in the oral fissure to infect the wound. The infection can and so spread to the surrounding tissue next to the nail and cuticle.
• Felon: This bacterial infection of the finger pad, caused by the aforementioned organisms that cause paronychia, is usually the issue of a puncture wound. The wound allows the introduction of leaner deep into the fingertip pad. Because the fingertip has multiple compartments, the infection is independent in this surface area.
• Herpetic whitlow: The offending viral organism is the herpes simplex virus type I or II. This is the same virus that causes oral or genital canker infections. People in certain occupations are more at risk for this infection. These include dentists, hygienists, physicians, nurses, or any other person who may have contact with saliva or body fluids that incorporate the virus. People with oral or genital herpes may also infect their ain fingers.
• Cellulitis: The nigh common causes of this bacterial infection are staphylococcal and streptococcal organisms. This infection is usually the upshot of an open wound that allows the leaner to infect the local peel and tissue. The infection can also spread to the hand and fingers by claret carrying the organisms.
• Infectious flexor tenosynovitis: This bacterial infection is usually the upshot of penetrating trauma that introduces bacteria into the deep structures and tendon sheaths, which allows the spread along the tendon and associated sheath.
• Deep space infection: This bacterial infection is commonly the result of a puncture wound or deep cutting that introduces the bacteria to the deep tissue. The collar push button abscess is associated with the web infinite betwixt the fingers. The deep structures of the hand create many potential compartments for an infection to invade.

Finger Infection Symptoms

Each of the main finger infections has specific signs and symptoms that make identification unique and can sometimes crusade confusion if not properly evaluated.

• Paronychia: The area next to the fingernail will appear red and swollen. A visible collection of pus may be seen under the skin and boom. This fluid may be actually leaking out of the wound. The expanse volition be tender and painful to the touch. The drainage from the expanse is usually a cloudy white-xanthous color.
• Felon: The fingertip is bloated and painful. The swelling usually develops over several days and is located in the pad surface area of the fingertip. The area volition have a throbbing hurting and be painful to the bear on. The area is ordinarily red, and a visible collection of pus may be seen under the skin. The swollen area may have a portion that feels soft as if information technology contains fluid. As the swelling continues, the area may become tense or hard to the touch.
• Herpetic whitlow: The fingertip area will be red and tender. A called-for or itching awareness may be present in the area. At that place may be balmy swelling, but not every bit extensive as in the felon. There may be a single or many open wounds in the area affected. These open up wounds often occur in clusters later on the formation of a small blister-similar lesion. The fluid in these lesions is usually articulate in appearance but may be slightly cloudy.

• Cellulitis: The surface area will exist red and warm to the touch on. The expanse may be slightly swollen and tender. This is usually a superficial infection, so the deep structures should not exist involved. The motion of the fingers and paw should not exist difficult or painful. If painful or difficult, this may indicate a deep infinite infection of some type.
• Infectious flexor tenosynovitis: Four major signs often are found with this condition. First is tenderness over the flexor or palm side of the finger. This pain is establish over the tendons in the finger. 2d is uniform swelling of the finger. Tertiary is pain on extending or straightening of the finger. Quaternary, the finger volition be held in a slightly flexed or partially aptitude position. These signs are called Kanavel fundamental signs. All iv signs may not be nowadays at first or all at once.
• Deep space infections: The deep space infection that arises in the web space of the fingers is also called a neckband push abscess. The space between the fingers will be painful and swollen. The expanse may also be red and warm to the touch. As the abscess becomes larger, the fingers will exist slightly spread apart by the increasing pressure.

  • Herpetic whitlow: A history of contact with body fluids that may contain the herpes virus will aid the diagnosis. The diagnosis tin oft be made from the history and the appearance of the lesions. The presence of a clear fluid from the wounds may indicate a viral infection rather than a bacterial infection. A sample of the fluid may be analyzed by a Tzank smear, which volition identify sure cells, indicating a viral cause.
  • Cellulitis: The doc will need to consider other causes that may look like such every bit gout, various rashes, insect sting, burns, or claret clot earlier the terminal diagnosis is made. An 10-ray may be obtained to wait for a foreign body or gas formation that would betoken a type of serious cellulitis.
  • Infectious flexor tenosynovitis: A history of a puncture wound or cut will aid the diagnosis. The presence of the 4 Kanavel cardinal signs is a stiff diagnostic aid. A recent sexually transmitted disease may indicate a type of gonorrhea-related infection, which may resemble infectious flexor tenosynovitis.
  • Deep space infections: A history of puncture wound or other wound may aid the diagnosis. The finding of swelling between the fingers with a wearisome spreading of the involved fingers will help identify a collar button abscess.

The doctor volition and then insert an instrument into the wound and break up the compartments to aid in the drainage. Sometimes, a piece of safety tubing or gauze will be placed into the wound to aid the initial drainage.

Because of the intricate nature of the fingers and hands, a hand surgeon will usually perform this procedure.
