Osteoporosis is a condition where bones become weak and brittle, making them more likely to break. It often affects older adults, especially women after menopause, and can lead to serious fractures that impact mobility and quality of life.
Osteoporosis is a skeletal disorder characterized by compromised bone strength, predisposing individuals to an increased risk of fracture. It results from a combination of decreased bone mineral density (BMD) and deterioration of bone microarchitecture.
| Condition | Distinguishing Feature |
|---|---|
| Osteomalacia | Characterized by impaired bone mineralization, often due to vitamin D deficiency, leading to bone pain and muscle weakness, distinct from the reduced bone mass of osteoporosis. |
| Hyperparathyroidism | Excess parathyroid hormone leads to increased bone resorption and hypercalcemia, which can mimic osteoporosis but often has distinct biochemical abnormalities. |
| Metastatic Bone Disease | Malignant infiltration of bone causes pain and potential fractures, but typically presents with focal lesions on imaging and often associated systemic symptoms of malignancy. |
| Paget's Disease of Bone | A chronic disorder of abnormal bone remodeling, leading to enlarged and deformed bones, typically presenting with localized bone pain and characteristic radiographic findings. |
| Rheumatoid Arthritis | An inflammatory arthropathy that can lead to secondary osteoporosis due to chronic inflammation and corticosteroid use, but primarily affects joints with inflammation and stiffness. |
| Multiple Myeloma | A plasma cell malignancy that causes lytic bone lesions and osteoporosis, often associated with anemia, renal impairment, and hypercalcemia. |
Management focuses on preventing fractures through lifestyle modifications (adequate calcium and vitamin D intake, weight-bearing exercise, smoking cessation, limiting alcohol), pharmacotherapy (bisphosphonates, denosumab, teriparatide, romosozumab), and fall prevention strategies.
