What characterizes Osteogenesis Imperfecta?

• A. Absence of vertebral arches
• B. A disorder leading to brittle bones
• C. Paralysis of one limb
• D. A congenital heart defect

Answer: (B)

Osteogenesis Imperfecta is primarily characterized as a disorder that leads to brittle bones. This genetic condition affects the body's ability to produce collagen, an important protein that helps to provide structure and strength to bones. As a result, individuals with Osteogenesis Imperfecta experience a higher susceptibility to fractures, often with minimal or no trauma. This brittleness of the bones is a hallmark of the condition, distinguishing it from other disorders that might involve bone formation or structural abnormalities. The other options describe conditions or aspects that do not align with the primary characteristics of Osteogenesis Imperfecta. For example, the absence of vertebral arches pertains to a different type of skeletal issue, paralysis specifically points to a disruption in nerve function rather than bone integrity, and congenital heart defects refer to heart abnormalities present at birth, which are unrelated to the symptoms or characteristics of Osteogenesis Imperfecta. Therefore, the correct characterization of this disorder is its impact on bone fragility.
