Living with Isolated osteopoikilosis

A rare bone condition with small, dense spots in the bones that usually causes no symptoms and is found by chance.

Understanding Isolated osteopoikilosis

Isolated osteopoikilosis is a rare bone condition with multiple small, round, dense spots in the bones.

The spots show up most in the ends of long bones, the pelvis, and the hand and foot bones. It usually causes no symptoms and is found by chance on X-rays. Some people have mild joint pain, with or without fluid in the joint. Bone strength is normal. It can be noticed from childhood to adulthood.

Signs & symptoms

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

  • Small dense spots in the bones
  • Spots in the pelvis and long bones
  • Spots in hand and foot bones
  • Increased bone density
  • Mild joint pain in some people

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 LEMD3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
