Evaluation of the adult patient (aged >40 years) with a destructive bone lesion
1Department of Orthopaedic Surgery and the Sarcoma Center, Johns Hopskins School of Medicine, Baltimore, MD, USA.
Abstract:
More than one half of cancer patients are likely to develop bone metastasis; thus, most orthopaedic surgeons will be presented with an adult patient with a destructive bone lesion. Proper management requires comprehensive patient evaluation, including history, physical examination, laboratory studies, and radiographic staging. Biopsy should be done in the patient with a possible malignant or metastatic tumor. The differential diagnosis of destructive bone lesions in patients aged >40 years includes metastatic bone disease, multiple myeloma, lymphoma, and, less commonly, primary bone tumors. Inaccurate diagnosis and improper treatment may adversely affect limb or life. Adherence to oncologic principles during the evaluation process aids in minimizing a negative outcome.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
