What are the symptoms of brittle bone disease

Many people have eaten cartilage, whether it is pork, chicken or duck. In addition to these animals, humans also have brittle bones, but brittle bones in the human body are a disease caused by incomplete skeletal development. Most people's bones are relatively complete, and people with brittle bone disease are very likely to receive injuries, such as fractures. So what are the symptoms of brittle bone disease?

1. Easy fracture

Because of osteoporosis, fractures are very likely to occur with the slightest movement, but the amazing thing is that the fractures can heal themselves, but the process is very slow. The skull of this type of patient is very thin, with scattered irregular calcification foci. In severe cases, it looks like a membrane bag, and the child's fontanelle will also be delayed in closing. There are also lesions on the skin and sclera.

2. Blue eyes

Although blue eyes are beautiful, if it is a kind of morbid beauty, it will be harmful to health. Children with brittle bone disease will have blue sclera, which makes their eyes look beautiful, but it is indeed a manifestation of brittle bone disease. The sclera is translucent, which is caused by changes in the properties of collagen fiber tissue.

3. Deafness

This condition usually occurs between the ages of 11 and 40. The main reason may be that the ear canal is hardened and the stapes footplate attached to the oval window is fixed due to bony ankylosis. This is very different from congenital deaf-mute people. This acquired deafness will bring greater pain to the patients.

4. Excessive relaxation of joints

Due to the developmental disorder of collagen tissue in tendons and ligaments. There may also be knock knees, flat feet, etc. The clinical manifestations include habitual shoulder dislocation and radial head dislocation. This joint laxity may affect the wrist and ankle joints. It will also cause some trouble to the patient's movements.

5. Poor tooth development

Because the tooth structure cannot develop well, both the ingrown teeth and permanent teeth will be affected, and they will either easily develop caries or fall out.
