What is considered the most serious consequence of osteoporosis?

• A. Vertebral fracture
• B. Hip fracture
• C. Wrist fracture
• D. Rib fracture

Answer: (B)

Osteoporosis raises the overall risk of fracture, but the outlook after a hip fracture is typically the most severe. This fracture usually needs surgery and lengthy rehabilitation, and it often leads to prolonged immobilization. That immobilization increases the risk of complications such as pneumonia, blood clots, delirium, and muscle deconditioning, and many older adults do not regain their prior level of independence. In contrast, vertebral fractures, while painful and resulting in height loss and spinal deformity, are less consistently linked to immediate life-threatening complications, and wrist fractures—though painful—rarely result in the same level of functional decline or mortality. Rib fractures tend to be less disabling in the context of osteoporosis. Because of the high mortality and substantial loss of function associated with hip fractures, they are considered the most serious consequence of osteoporosis.
