Analysis:

Osteogenesis imperfecta (OI) is a congenital genetic disorder that occurs in about equal proportions in men and women. It causes a defect in type I collagen fibers, which makes the bones less able to withstand the impact of external forces, and can cause severe fractures in the event of even a minor collision. This is why these patients are called "glass dolls.

Guidance:

Also known as brittle bone disease, it is mainly characterized by easy fracture of various parts of the body. More than 15% of patients have a family history of heredity, so it is best not to have children with this disease. Currently there is no special treatment, mainly to prevent fractures and symptomatic treatment. Some of them can recover spontaneously after 18 years of age.
