Incidence, location, and diagnostic evaluation of metastatic bone disease

Metastatic carcinoma is the most common malignancy of bone. The clinical presentation of patients with skeletal metastasis is variable. When asked to evaluate a patient with a pathologic lesion or unexplained bone pain, the orthopedic surgeon should follow a logical sequence of steps in evaluating the patient with suspected metastasis to optimize care and avoid complications. In the majority of cases, a systematic approach to the patient with skeletal metastasis leads to the correct diagnosis.
