Question

Stress fractures secondary to osteoporosis occur most often in the vertebrae, the femur, and the:

a) Humerus
b) Tibia
c) Radius
d) Fibula

Answer 1

The correct answer is b) Tibia. Stress fractures due to osteoporosis are most commonly found in the vertebrae, femur, and tibia.

Answer 2

Stress fractures secondary to osteoporosis occur most often in the vertebrae, the femur, and the tibia.

Step-by-step explanation:

Stress fractures that occur as a result of osteoporosis most commonly affect bones that bear a significant amount of weight or are subjected to repetitive stress. Alongside the vertebrae and femur, the other bone that is prone to stress fractures due to osteoporosis is the tibia.

The tibia, commonly known as the shinbone, is one of the weight-bearing bones in the lower leg. Given its role in supporting body weight during activities like walking and running, it is susceptible to stress fractures, especially in individuals with osteoporosis. The weakened bone structure resulting from osteoporosis makes the tibia more prone to fractures under repetitive stress.

While the humerus, radius, and fibula are also bones in the body, they are less commonly associated with stress fractures caused by osteoporosis compared to the vertebrae, femur, and tibia, which bear more weight and are subject to increased stress during daily activities.
