Are Broken Bones Stronger After They Heal?

The video debunks the myth that bones become stronger after healing from a fracture. It explains the bone healing process, including the formation of a soft and then hard callus, which may temporarily be stronger due to its size. However, this strength is not permanent, and the remodeled bone is typically as strong as the original. The video also discusses factors that may lead to re-fracture, such as inactivity during healing, and emphasizes that regular exercise can strengthen bones by promoting mineral density.

What is the common misconception about bones after they heal from a fracture?

• They become more flexible.

• They remain the same strength.

• They become permanently stronger.

• They become permanently weaker.

During the bone healing process, what is the initial structure that forms to bridge the fracture?

• Soft callus

• Hard callus

• Lamellar bone

• Woven bone

What happens to the hard callus after it forms during bone healing?

• It remains permanently.

• It is remodeled into lamellar bone.

• It turns into cartilage.

• It is absorbed by the body.

Why might a bone be more likely to break again after healing?

• The bone was weakened from lack of use during healing.

• The person engages in risky activities.

• The bone was not set properly.

• The new bone is inherently weaker.

How can individuals strengthen their bones to prevent fractures?

• By avoiding physical activity.
