Purulent dactylitis

Introduction to purulent finger inflammation Purulent finger inflammation is a subcutaneous tissue purulent infection of the palm of the hand, which is caused by stab wounds. The palm of the palm of the hand is called the abdomen, and the far side refers to the fibrous septum under the skin of the transverse stripes, which makes the finger abdomen form a closed gap under the skin. The finger is divided into many small intervals by the fiber cord, and the small interval is filled with fat balls. Here the skin is thick, hard and tough, lacks elasticity, and the nerve receptors are very rich. Once the infection occurs, the tension of the finger is obviously increased, and the pain is remarkable. The subcutaneous tissue directly connects with the distal phalanx. Therefore, purulent finger inflammation is easy to develop into apical suppurative osteomyelitis, purulent finger inflammation, often caused by minor injury or stab wound, and the pathogenic bacteria are mostly Staphylococcus aureus. basic knowledge The proportion of illness: 0.84% Susceptible people: no specific population Mode of infection: non-infectious Complications: ischemic necrosis osteomyelitis

Causes of purulent finger inflammation

(1) Causes of the disease

Often caused by minor injuries or stab wounds.

(two) pathogenesis

There are many longitudinal fiber cables between the skin on the palm of the finger and the periosteum of the nail. The soft tissue is classified into many closed small cavities. The cavity contains adipose tissue and a rich network of nerve endings. When the infection occurs, the pus does not easily spread to the surrounding area. The swelling is not significant, but the formation of a high pressure abscess can not only cause very severe pain, but also oppress the nourishing blood vessels of the distal phalanx, causing ischemia and necrosis of the phalanx. In addition, the pus directly invades the phalanx and can also Causes osteomyelitis.

Purulent finger inflammation prevention

Pain occurs at the fingertips. If the swelling is not obvious, it can be soaked several times with hot salt water for about 20 minutes each time. It can also be applied externally (see treatment of paronychia), and sulfa drugs or antibiotics should be applied as appropriate. Pay attention to proper rest, do not master the combination of movement and rest, rest well, is conducive to the recovery of the body, exercise can enhance physical strength.

Purulent finger inflammatory complications Complications ischemic necrosis osteomyelitis

The treatment of this disease is timely, the pus is healed, the prognosis is good, but if misdiagnosed and mistreated, most of the distal part of the tissue is ischemic necrosis, the nerve endings are paralyzed due to pressure and nutrition disorders, but the pain is reduced, which can cause phalanx ischemic Necrosis, leading to osteomyelitis of the phalanx.

Acne finger inflammation symptoms Common symptoms Fever soft tissue swelling Appetite leukocytosis fatigue fingertip pain or tenderness

Local pain is the main symptom of suppurative finger inflammation. It starts with less pain and is acupuncture-like. Later, due to tissue swelling, the pressure in the gap increases, the peripheral nerve is compressed, the pain is aggravated, with pulse pain, when the hand is drooping or tapping When it is used, it often causes pain that the patient can't bear, especially when it is quiet at night. It often makes it difficult for the patient to fall asleep. After the infection, the skin of the fingertips is red and swollen. Afterwards, the redness does not increase, and sometimes it is yellowish white. This is due to stress. Increased obstruction of blood supply, purulent finger inflammation, generally have varying degrees of systemic symptoms, such as chills, fever, headache, loss of appetite, fatigue and increased white blood cell count.

Examination of purulent finger inflammation

1, blood routine examination: the total number of white blood cells and neutrophils increased.

2, X-ray examination: can be found in the phalanx osteomyelitis or dead bone.

3, light test pus examination: fingertips have dark black shadows, indicating that pus has formed.

Diagnosis and diagnosis of purulent finger inflammation

According to the medical history, clinical systemic manifestations, local symptoms, laboratory tests, a diagnosis can be established.

Differential diagnosis

1, knuckle tuberculosis: occurs mostly in the middle of the finger, the skin color is not red at the beginning, the skin temperature is not high, no pain, the local swelling is hard in the middle, the course of the disease is slow, and the thin pus collapses after several months or years. Laboratory bacteria cultured with Eosinophilic growth, X-ray film showed typical caseous necrosis.

2, fingertip infection and subcutaneous abscess: fingertip redness, subcutaneous white pus, mild pain, no jumping pain, redness and tenderness confined around the trauma, no systemic symptoms and laboratory positive physical evidence.
