Skeletal Dysplasia Program

Internationally Recognized Care for Skeletal Dysplasia

91 Children’s is a world leader in caring for children with skeletal dysplasia. We see more kids with skeletal dysplasia than nearly any other pediatric children’s hospital.

Skeletal dysplasia is a group of conditions related to bone development, bone structure and bone strength. Dwarfism, or having short stature, and brittle bones are two common types. But there are about 500 types of skeletal dysplasia.

At 91, many specialists come together to treat kids with skeletal dysplasia. We evaluate, do genetic testing and offer the latest surgical and non-surgical treatments. We see people from birth up to age 35.

Our team has spent decades researching and treating rare and complex types of skeletal dysplasia. We provide all the care you need, under one roof.
