Felon (dactylic) - acute purulent inflammation of the fingers (usually on the hand; on the leg felon almost never occurs). The main reason felon - injured finger (often his nail phalanxes), infected pyogenic bacteria. Especially dangerous puncture wounds and splinters. There are felon superficial skin, okolonogtevogo and subungual; felon deep - subcutaneous, tendon, bone and joint (Fig. 1).

Fig. 1. The main forms of felon (scheme): 1 - skin; 2 - subcutaneous; 3 - tendon; 4 - bone; 5 - articular; 6 - felon in the form of cufflinks.

With the defeat of all the tissues of the finger felon called pandactylitis. A felon is a serious disease; even surface forms an incorrect treatment can lead to severe damage not only your finger, and all of the brush.
When skin (bullous) panaritium pus becomes concentrated under the epidermis, Uslava it and forming on her finger purulent bubble; often appears lymphangitis (see), priuchayut the regional lymph nodes. Pain usually not very strong. Treatment: carefully (without anesthesia) to open the bubble scissors, completely remove debonded epidermis, apply antiseptic ointment dressing (syntomycin emulsion or Vishnevsky ointment and others). Daily baths of antiseptic solution (potassium permanganate 1 : 5000 or Lysol of 0.5%). Careful removal of epidermis around the edges, if he continues to pull away and beneath it becomes concentrated pus, after - dressing.
Okolonogtevogo felon (paronychia) - is called the shots under the nail wall, often associated with damage when manicure. Pain, swelling, redness of the nail fold, education purulent bubble on it. Pus may be distributed in the nail bed, when running paronychia may damage the bone (nail tuberosity phalanges). Treatment both in skin panaritium. If after opening the bubble continues the pus from under a nail, begins the growth of granulation, then struck the nail bed and requires removal of the nail - full or partial, which requires local anesthesia novocaine. The patient should be sent to the surgeon.
Subungual felon develops from paronychia or due to the implementation under the free edge of the nail any splinters, needles, etc., Pus becomes concentrated under the nail plate, Uslava her. Severe pain, often lymphangitis, through the nail Shine through pus. Treatment: if the process is started from the end of the nail (for example, after the shot) and has not spread,carefully, with the tip of a knife to make the cut at the free edge of the nail plate, dressings with hypertension (10%) a solution of sodium chloride. With extensive detachment nail shown its complete removal under local anesthesia, then the treatment, as in skin panaritium.

Felon (from lat. panaricium - noted) - acute purulent inflammation of the finger, in most cases occur when infected micro traumas (scratches, cracks, injections with a needle or shilom, and so on). Inflammation of the finger, caused by a specific infection (e.g., syphilis), is called ductility. When significant open injuries of fingers process flows as when an infected wound, without features, characteristic for a felon. The most frequent pathogens P. - Staphylococcus, Streptococcus, often sour cream flora, sometimes putrid (wounds from the bites). P. usually develops on finger and only occasionally on the toe.
Incorrect treatment of P. can lead to serious complications, up to a complete loss of function of the finger, and sometimes even brush. If one of the middle fingers will remain after P. motionless, straightened, it will severely hamper the function of the brush. The most dangerous purulent processes in the tissues of the Palmar surface of the finger. Suppuration on the rear of it (except for nail phalanxes) generally no danger.
Localization of process in tissues finger distinguish P. skin, nail (subungual and okolonogtevogo), subcutaneous, tendon, bone, joint, lymph. Defeat all the tissues of the finger called pandactylitis.
