Most patients with osteoporosis are asymptomatic unless they suffer a fragility fracture. A fragility fracture is a type of pathological fracture that occurs as a result of normal activities, such as lifting, bending, or a fall from standing height or less. There are three fracture sites said to be typical of fragility fractures: vertebral fractures; fractures of the neck of the femur; and Colles' fracture of the wrist. Following fracture risk assessment a dual energy X-ray absorptiometry (DXA) scan may be recommended.
