Brief description:

This is an idiopathic disorder of the bone leading to bone remodelling, which weakens the bone structure. It is often asymptomatic and diagnosed incidentally during imaging for other pathology.  It occurs in aging patients, typically after 55 years of age.

Confirming the diagnosis

Diagnosis usually requires X-rays showing a characteristic appearance.  Blood and urine tests can also help confirm the diagnosis.  Bone scans can show the extent of the disease. The relevant medical specialist is an endocrinologist, rheumatologist or orthopaedic surgeon.
