Types of Bone Fractures and X-rays

The lecture covers the discovery and use of X-rays, explaining how modern X-ray machines work and their applications in diagnosing injuries and diseases. It delves into dislocations, their causes, and effects on the body. The lecture also provides a comprehensive overview of fractures, including their classification and various types, such as transverse, oblique, spiral, and more.

Who discovered the ability of X-rays to pass through the body?

• Albert Einstein

• Marie Curie

• Isaac Newton

• Wilhelm Röntgen

What is the primary use of X-rays in medicine?

• To treat cancer

• To diagnose injuries and diseases

• To measure bone density

• To perform surgeries

What is a dislocation?

• A displacement of bones at the joint

• A break in the bone

• A fracture that occurs at a 90-degree angle

• A twisting fracture

Why can dislocations be more painful?

• Because they are always open fractures

• Because they involve broken bones

• Because they heal quickly

• Because they involve damaged ligaments and tendons

What causes a fracture?

• A lack of calcium

• A genetic disorder

• A viral infection

• A physical force greater than the bone's strength

What is a displaced fracture?

• A fracture where the bone ends are out of alignment

• A fracture that occurs in multiple pieces

• A fracture where the bone ends are aligned

• A fracture that does not break the skin

Which type of fracture occurs at a 90-degree angle to the bone's axis?

• Greenstick fracture

• Transverse fracture

• Spiral fracture

• Oblique fracture

What is a spiral fracture?

• A fracture that occurs in multiple pieces

• A twisting fracture

• A fracture that occurs at a sloped angle

• A fracture where bone bends rather than breaks

What is an avulsion fracture?

• A fracture that occurs at a sloped angle

• A fracture that is incomplete and has multiple small lines

• A fracture that occurs in the middle of a bone

• A fracture where a fragment of bone breaks off due to a tendon or ligament pulling away

Which fracture type is characterized by bone bending rather than breaking?

• Transverse fracture

• Greenstick fracture

• Impacted fracture

• Fissure fracture
