rib osteomyelitis
Introduction
Introduction to rib osteomyelitis Rib osteomyelitis is relatively rare, the pathogenesis is divided into three types: blood-borne rib osteomyelitis, traumatic or iatrogenic rib osteomyelitis, inflammation and radioactive rib osteomyelitis. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: elbow joint rigidity
Cause
Cause of rib osteomyelitis
Secondary infection (80%):
Most of the rib osteomyelitis is secondary to Staphylococcus aureus, Streptococcus, Pseudomonas aeruginosa and Mycobacterium tuberculosis, and Klebsiella can cause this disease.
The disease can be caused by the following four ways:
1 pneumonia, empyema, carbuncle and other purulent diseases, pathogenic bacteria through the blood circulation to the ribs growth and reproduction.
2 chest wall soft tissue purulent infection directly spread to the ribs.
3 open thoracic injuries, especially with rib fractures caused by rib infection.
4 rib infection after thoracotomy.
Prevention
Rib osteomyelitis prevention
There is nothing that needs too much attention, mainly early detection of early treatment.
Complication
Rib osteomyelitis complications Complications elbow joint rigidity
(1) Malformation: As the epiphysis is stimulated by inflammation, the affected limb grows excessively and becomes longer, or the bone plate is damaged, which affects the development. As a result, the limb is shortened, the side of the epiphyseal plate is damaged, and the development is asymmetrical, so that the joint is inside. Folding or valgus deformity; due to soft tissue scar contracture, it can also cause flexion deformity.
(2) Joint rigidity: As the infection spreads into the joint, the articular cartilage surface is destroyed, making the joint fibrotic or bony.
(3) Carcinogenesis: The skin of the sinus ostium can be combined with cancer due to continuous stimulation. It is usually squamous cell carcinoma.
Symptom
Rib bone marrow inflammation symptoms Common symptoms Post-sternal burning pain, loss of appetite, heart tingling, leukocytosis, infectious fever, bone destruction
Local redness, swelling, heat, pain, chronic history can be seen in the chest wall sinus.
According to the suppurative infection of other parts of the body, the sternum is swollen and painful, and the bone destruction of the chest X-ray rib can be clearly diagnosed.
Examine
Examination of rib osteomyelitis
Chest X-ray: The ribs have osteolysis damage.
Diagnosis
Diagnosis and diagnosis of rib osteomyelitis
Local redness, swelling, heat, and pain appear in the chest wall. When the inflammation is severe, systemic symptoms such as fever and loss of appetite may occur. Chronic history can be seen in the chest wall sinus.
Blood routine examination of white blood cell count increased, the proportion of neutrophils increased, chest X-ray examination showed local thickening of the diseased ribs, bone dissolution and destruction, may have signs of pleural reaction. If the treatment is not timely, the abscess can penetrate the skin to form the sinus, and penetrate the pleura to form the empyema. The course of the disease enters the chronic phase, and there may be recurrent sinus and dead bone on the skin. According to the suppurative infection of other parts of the body, the sternum is swollen and painful, and the bone destruction of the chest X-ray rib can be clearly diagnosed.
