-Bone pain is continuous. Unlike the pain of OA, the bone pain of Paget’s disease usually increases with rest, when the limbs are warmed, and at night. Bowing may occur in Tibia. Alkaline Phosphatase is elevated but GGT is normal.
-Most common neurologic complication = Hearing loss from cochlear damage.
“CONCLUSIONS:
We recommend that plain radiographs be obtained of the pertinent regions of the skeleton in patients with suspected Paget’s disease. If the diagnosis is confirmed, we suggest that a radionucleotide bone scan be done to determine the extent of the disease. After diagnosis of Paget’s disease, we recommend measurement of serum total alkaline phosphatase or, when warranted, a more specific marker of bone formation or bone resorption to assess the response to treatment or evolution of the disease in untreated patients. We suggest treatment with a bisphosphonate for most patients with active Paget’s disease who are at risk for future complications. We suggest a single 5-mg dose of iv zoledronate as the treatment of choice in patients who have no contraindication. In patients with monostotic disease who have a normal serum total alkaline phosphatase, we suggest that a specific marker of bone formation and bone resorption be measured, although these may still be normal. Serial radionuclide bone scans may determine the response to treatment if the markers are normal. We suggest that bisphosphonate treatment may be effective in preventing or slowing the progress of hearing loss and osteoarthritis in joints adjacent to Paget’s disease and may reverse paraplegia associated with spinal Paget’s disease. We suggest treatment with a bisphosphonate before surgery on pagetic bone.” https://www.ncbi.nlm.nih.gov/pubmed/25406796
