Living with Worth disease

A bone condition in which bones become denser, mostly in the skull and long bones, without a higher risk of fracture.

Understanding Worth disease

Worth disease (endosteal hyperostosis, Worth type) is a bone disorder with generally denser bones, especially in the skull and long bones.

GARD says it is not linked to a higher risk of fracture. It usually shows in the teen years. Features include excess bone growth in the skull and face, and a bony bump on the roof of the mouth.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Denser bones throughout the body
  • Extra bone growth in the skull and face
  • Denser collarbones
  • Denser spine bones
  • Bony bump on the roof of the mouth (torus palatinus)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists and genetic specialists.

  3. Consider genetic testing

    Changes in LRP5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
