Skeletal dysplasia is not just one disorder—it’s a group of more than 300 disorders. It occurs when a child’s bones don’t develop the way they’re supposed to, usually causing short stature. One type of short stature is called dwarfism. It’s a condition where a child’s bones can’t grow to an average length. This results in the bones being short and sometimes crooked. A patient is considered to have dwarfism when their adult height is 4 feet 10 inches or less.
