Syphilitic osteochondritis

Introduction to syphilitic osteochondritis The pathogen of syphilis is Treponema pallidum, and 60% of patients may have bone and joint damage. Treponema pallidum is mainly transmitted through sexual contact and can also invade the fetus through the placenta. Therefore, syphilis has two kinds of congenital and acquired. More than 70% of congenital bone syphilis can invade the epiphysis, called osteochondritis, and also invade the periosteum and bone marrow. In adults, changes in bone and joint mainly occur in advanced syphilis. basic knowledge The proportion of illness: 0.001% Susceptible people: infants and young children Mode of transmission: sexual contact, blood transmission Complications: fracture

Causes of syphilitic osteochondritis

(1) Causes of the disease

The syphilitic osteochondritis is mainly seen in the half year after the birth of the baby. The bacteria often invade the metaphysis of the long bones of the extremities, and form syphilitic granuloma locally, which destroys the epiphyseal line and thus prevents bone development.

(two) pathogenesis

Treponema pallidum is mainly transmitted through sexual contact, and can also invade the fetus through the placenta. Therefore, syphilis has two kinds of congenital and acquired genital, more than 70% of congenital bone syphilis can invade the epiphysis, called osteochondritis, and also invade the periosteum and bone marrow; In adults, the changes in bone and joint mainly occur in the late stage of syphilis. In addition to osteochondritis, the lesions of congenital syphilis are the same as adults.

Syphilitic osteochondritis prevention

1. Isolation and treatment of infectious sources: syphilis patients are the main source of infection for syphilis. Early detection and early cure are the fundamental ways to eliminate the source of infection.

2. Protection of the second generation: There is no vaccine for artificial immunization, so pre-marital and prenatal examinations should be strengthened. If you find that you have syphilis, you can get married after healing; if you get syphilis after marriage, you can get pregnant after curing; if you find syphilis after pregnancy, you should actively treat it in the early pregnancy to prevent infection of the fetus and baby.

3. Cut off the route of infection: syphilis is directly transmitted through sexual contact. Therefore, it should have a good sexual ethics, strict sexual life with one wife, pay attention to personal hygiene, cleanse and self-love. If one party has been infected with syphilis, the other party should be advised to go to the hospital for examination, and both parties should be treated at the same time.

Syphilitic osteochondritis complications Complications

There is a dry fistula that can be complicated with incarcerated fractures.

Symptomatic osteochondritis symptoms Common symptoms Joint swelling Mucosal damage Muscle atrophy

In the early stage of the disease, it mainly manifests as local swelling and pain. Because of the pain, the child is reluctant to move the limbs and crying. The child may also have pseudo-sickness due to pathological relaxation in the dry mouth. At this time, the child is very weak. Wrinkles can be formed due to the lack of subcutaneous fat. At the same time, the affected limbs may have muscle atrophy due to local lesions, joint swelling and tenderness.

Examination of syphilitic osteochondritis

The serum Kang-Hua reaction showed positive.

X-ray plain film shows that the epiphysis is widened, and the density of the white line is about 3mm wide at the sacral line. The serrated edge of the epiphysis is facing, the translucent band with the average density is reduced between the white line and the backbone, and the embedding can be incarcerated. fracture.

Diagnosis and diagnosis of syphilitic osteochondritis

The diagnosis of this disease is not difficult. In addition to the general medical history, the family history should be followed. The mother has a history of syphilis. Clinically, when the child has multiple bone and joint lesions, the disease should be considered. In addition, according to the whole body skin. Mucosal damage, bone and joint performance and serum Kang-Hua reaction results can generally be diagnosed.
