Shriners Hospitals for Children® - Tampa prides itself on treating everyone who comes to the hospital like family. That includes 14-year-old Riley Desin, who was born with a genetic condition called hereditary multiple exostoses (HME), which causes his bones to grow bumpy, rather than straight and smooth.
In Riley's case, which is considered severe, physicians discovered growths from nearly head to toe through a full body X-ray. When he was 14 months old, Riley's parents noticed a bowing in his left arm. He also was complaining of pain in his ring finger, preventing him from straightening it. Though the condition is genetic, Riley is the first in his family to be diagnosed with HME. However, his children will have a 50 percent chance of inheriting the disorder.
