Living with Idiopathic juvenile osteoporosis

A bone condition that begins in childhood, with thin, brittle bones that break easily.

Understanding Idiopathic juvenile osteoporosis

Idiopathic juvenile osteoporosis is a skeletal disorder in which the bones become thin, starting in childhood.

Bones have too little calcium and other minerals, so they are brittle and prone to breaks. Fractures often happen in the long bones of the arms and legs and in the bones of the spine. Multiple fractures can cause bone pain and movement problems.

Signs & symptoms

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

  • Thin, brittle bones (osteoporosis)
  • Repeated fractures
  • Bone pain
  • Collapsed bones in the spine (vertebral compression fractures)
  • Changes in the way a person walks
  • Hunched back (less common)

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 autoimmune and inflammatory disease specialists, bone and joint specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
