Osteochondritis - inflammation of the cartilage and the adjacent area of the bone. The reason for osteochondritis often tuberculosis, syphilis (congenital), less conventional purulent infection. Symptoms and treatment - see Osteomyelitis, Tuberculosis of bones and joints.

Osteochondritis (osteochondritis; from the Greek. osteon - bone, chondros - cartilage)- inflammation of the subchondral Department bones, resulting from the influence of infections: tuberculosis, congenital syphilis, less often nonspecific purulent infection, From osteochondritis should distinguish the subchondral processes non-inflammatory origin, characterized by the appearance of lesions avascular necrosis in the corresponding area of the bone. Such, for example, Perthes disease, a disease of the blunt, sciatic-pubic osteochondrosis and other forms merged into the group of osteochondropathy (see).
Infectious osteochondritis observed in heavy septic arthritis and severe forms epimetopinae acute hematogenous osteomyelitis in children and adolescence. In late surgical treatment in case of incomplete ossification epiphyseal cartilage marked complete separation and sequestration of epiphysis. With the use in surgical practice antibiotics such complications are rare. The most important syphilis osteochondritis.

Osteochondritis in children (osteochondritis of Wegner). Syphilis osteochondritis (osteohondritis syphilitica) often affects children under the age of 3 months. This process causes the disorder of ossification and is located between the epiphysis and diaphysis; often affects the upper limb. Postmortem marked the increased deposition of lime in the cartilage cells, reduction and partial disappearance of bone rungs followed by the formation of necrotic areas.
As a result of such lesions may occur Department epiphysis from the metaphysis, the so - called disease Parra (pseudoparabolic Parra). A disease like flaccid paralysis of the extremities, but with true paralysis of the Central or spinal origin has nothing to do. In a sharply-cut cases the affected limb lies along the body, attempt to create passive movement causes a scream or a cry of a baby. Sluggish observed mainly on the upper extremities lower extremities at their defeat brought up to the stomach, which creates the impression of contractures. In the area of the affected joints, i.e. in places Department epiphysis from diaphysis, marked swelling (often it is observed in the shoulder and elbow joints); often during the study sick extremity mark the crepitation as if the fracture. The disease occurs not at once, as it happens in real paralysis, and develops gradually. In most cases Parra there are other symptoms of congenital syphilis.
Treatment and prevention of disease, Parra coincide with the treatment and prevention of congenital syphilis (see congenital Syphilis). Currently, when congenital syphilis has become extremely rare disease, the disease of Parra almost not observed.
