Tibial medial condyle osteochondrosis

Introduction to humeral osteochondrosis Intra-femoral osteochondrosis, also known as humeral varus or Blount disease. It refers to the knee varus deformity caused by dysplasia of the iliac crest. basic knowledge The proportion of the disease: the incidence rate is about 0.001% -0.005%, more common in young men Susceptible people: more common in young men Mode of infection: non-infectious Complications: knee varus

Causes of humeral osteochondrosis

The disease occurs in black children, which is significantly different from other osteochondrosis. The reason is unknown. Some people think that this is because black children walked earlier (average 1012 months) and white children later (15 months). Early walking caused excessive stress on the medial epiphysis of the humerus, resulting in malformation caused by cartilage development disorder. Some people think that this disease is caused by African black races, like to carry children on the body, two hip abduction, knee varus, on the inside of the tibia The pressure on the epiphysis is increased.

Prevention of humeral osteochondrosis

There is no effective preventive measure for this disease. Early diagnosis and early treatment is the key to the prevention and treatment of this disease, so as to avoid damage to the joints. As far as the suspected cause is concerned, preventing premature infants from walking is one of the measures to prevent this disease.

Complications of humeral osteochondrosis Complications

The disease mainly causes knee varus deformity, the child with long time and no timely treatment, the medial femur of the knee joint, the weight surface of the tibial cartilage can be defected and cystic, some children due to abnormal development, knee joint The ligaments can have significant slack performance.

Symptoms of humeral osteochondrosis in the humerus Common symptoms Chondroital dysplasia and... Knee varus deformity tibia trochanter swelling

The disease is mainly characterized by arched legs, which are divided into infant type and juvenile type (6-13 years old). The latter is rare, often caused by trauma and infection, and the deformity is not serious. Due to the position of the fetus in the uterus, most infants. There are arched legs, which are not corrected until 1 year old. Therefore, the disease should not be diagnosed before the age of 2 years.

Examination of humeral osteochondrosis

The auxiliary examination method of this disease is mainly X-ray examination. The X-ray findings are as follows: the affected side calf is inwardly curved, showing a knee varus deformity, and the humerus internal ankle is enlarged. The upper joint is facing inward, lower, and rearward, adjacent to the epiphysis. The medial part of the metaphysis also spreads inward, and uneven density or irregular calcification may occur, and the medial cortex of the humeral shaft is thickened. Knee arthrography shows that the articular surface of the humerus gradually develops from horizontal to collapse, and the medial meniscus is compensated. Abnormal thickening to maintain joint stability.

Diagnosis and diagnosis of humeral osteochondrosis

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

In the differential diagnosis, it is necessary to distinguish the early tibial iliac osteochondrosis and the physiological arched leg. The physiological arched leg is bilaterally symmetrical, and the entire medial tibial cortex is curved. The tibial iliac osteochondrosis can be unilateral. Sexuality, asymmetry, the angle of the medial cortex of the humerus is sharper, and the tip of the arch is closer to the end than the physiological one. The angle will be progressively increased, and the epiphysis or labial changes will occur in the medial aspect of the humerus. Wedge shape.
