Synopsis

A fracture that occurs from an underlying disease process that has weakened the bone, eg, cancer metastasis to bone, bone cysts, Paget disease, hyperparathyroidism, and osteoporosis. Pathologic fractures typically present with severe, localized pain after a very mild traumatic event, although they can occur with no trauma. Vertebrae and proximal long bones are the most common sites for pathologic fractures.

Pathologic fractures are sometimes the first presenting symptom of malignancy, though they most often occur in patients with a known primary cancer. Most pathologic fractures will require surgical intervention. Pathologic fractures due to malignancy are typically also treated with chemotherapy or radiation.
