The Claim

Adults with osteogenesis imperfecta type I exhibit significantly lower trabecular bone mineral content and volumetric bone density at the tibia and radius, and higher cortical bone mineral density, compared to healthy controls, resulting in reduced bone strength estimates as measured by polar stress–strain index, indicating persistent structural vulnerability in adulthood despite reduced fracture rates after childhood.

Description
1 study reviewed
In plain English

Adults with osteogenesis imperfecta type I have weaker internal bone structure in their shin and forearm bones compared to healthy adults, even though their outer bone layer is denser, leading to lower overall bone strength measurements that persist into adulthood despite fewer fractures after childhood.

See the scientific wording

Adults with osteogenesis imperfecta type I have significantly lower trabecular bone mineral content and volumetric bone density at the tibia and radius compared to healthy controls, despite higher cortical bone mineral density, resulting in reduced bone strength estimates as measured by polar stress–strain index, indicating a structural vulnerability that persists into adulthood despite reduced fracture rates after childhood.

Why this might work

The bone's outer layer becomes overly dense and stiff because of faulty collagen, which makes the bone less able to sense and respond to muscle forces. As a result, the inner spongy part of the bone doesn't build up enough material, even though the outer shell is thick and hard. This creates a weak internal structure that breaks more easily under stress, even if the outer bone looks strong.

    People with this bone disorder have weaker inner bone structure and thinner outer bone layers, even though their outer bone is denser than normal — making their bones more likely to break under stress, even as adults.
