Osteoporosis and Stress Fractures
Osteoporosis is a condition that causes bones to become brittle and break easily. This condition is more common in older adults, especially women after menopause. The problem starts with a decrease in bone density and loss of bone mass, usually affecting the spine, hips, and ribs. As a result, the bones become weak and more likely to fracture. These are called pathologic fractures; patients can also experience stress fractures if they engage in repetitive knee movements.
Osteoporosis is more likely to affect the elderly because they tend to have less muscle mass and fewer calcium deposits in their bones. The cause of osteoporosis is unknown, but it can be prevented with a healthy diet and exercise.
