Meet Marcellus
Marcellus has a condition known as Osteogenesis Imperfecta (OI) Type III Severe, more commonly known as Brittle Bones. OI is a genetic disorder characterized by bones that break easily, often from little or no apparent cause. A person with OI may have just a few or as many as several hundred fractures in a lifetime.
What is OI Type III:
OI Type III is the MOST SEVERE type among children who survive the neonatal period. The degree of bone fragility and the fracture rate vary widely. This type is characterized by structurally defective type I collagen. This poor quality type I collagen is present in reduced amounts in the bone matrix. Spine curvatures, compression fractures of the vertebrae, scoliosis, and chest deformities occur frequently.
