What Causes Osteitis?

Osteitis is currently considered to be a chronic viral infection. Causes of bone inflammation are different in different parts. Among them, compact osteitis is a osteoporotic disease, which occurs in young people aged 20 to 25. It is more common in women. It is easy to affect the sacrum, lumbar spine, and sacrum near the edge of joints. It occurs on one or both sides simultaneously. .

Causes of Osteitis

The etiology includes various hypotheses such as inflammation, tumors, endocrine disorders, abnormal blood supply, autoimmune, and inborn defects of connective tissue metabolism, but all lack sufficient evidence.

At present, the disease is considered to be a chronic viral infection. The evidence is:

1. Ultrastructural observations found that the nucleus and cytoplasm of osteoclasts have typical inclusion bodies (possibly a nuclear protein envelope of a paramyxovirus), which are very similar to the inclusion bodies in cultured cells of respiratory syncytial virus.

2. The disease has a long incubation period and presents a subacute clinical course.

3. The bone destruction and bone formation of this disease accompanied by fibrosis are a chronic inflammatory response.

4. A large number of multinucleated giant cells at the lesion site may be left over from multinucleated giant cells.

5. The onset of this disease is regional.

6. Many cases have family history.

Clinical manifestations of osteitis

The clinical manifestations are more mild, with mild tenderness or muscle spasms.

Osteitis examination

The sclerotic changes of the sacroiliac cortex near the articular surface can be seen on the plain X-ray film. The bone is dense, located at 1/2 below the sacroiliac joint and mostly triangular; the sacroiliac joint space is neat and clear. There were no signs of damage to the articular surface and bone. It is more common on one side, but also on both sides.

CT and MRI are generally not required for this disease, except for those who need to be differentially diagnosed with tumors and other lesions.

Osteitis diagnosis

A diagnosis can be made based on the examination.

Osteitis treatment

Non-surgical therapy

Mainly non-surgical treatment. Patients with mild symptoms can rest in bed properly and should be protected with an elastic waist after getting out of bed. Patients with severe symptoms can take analgesics and be protected with a stent. After the pain is reduced, patients are encouraged to do abdominal exercises and continue to use elastic waist protection.

2. Surgery

For patients with refractory pain, sacroiliac joint fusion surgery can be considered.
