Cartilage Hair Hypoplasia


Internationally Recognized Treatment for CHH and Related Complications


Nemours is world-renowned for treating skeletal dysplasias, including cartilage hair hypoplasia (CHH). The name “cartilage hair hypoplasia” comes from the small amount of fine hair people with this condition have. It’s also sometimes called metaphyseal dysplasia, McKusick type. If your child has CHH, or you need to get a diagnosis, we’re here to help. Our Nemours experts have the experience and training to answer your questions, ease your concerns, and build a coordinated long-term care team to help your child live life to the fullest.
