Questions and Answers

1.

Bone fragments into three or more pieces; common in the elderly
- A.
  
  Closed
- B.
  
  Open
- C.
  
  Comminuted
- D.
  
  Pott's fracture
- E.
  
  Greenstick
Correct Answer
C. Comminuted

Explanation
Comminuted fractures occur when a bone breaks into three or more pieces. This type of fracture is common in the elderly due to their bones being more brittle and prone to breaking. Unlike closed fractures, where the broken bone does not penetrate the skin, and open fractures, where the bone breaks through the skin, comminuted fractures involve multiple fragments of bone. Pott's fracture refers to a specific type of ankle fracture, and Greenstick fractures are incomplete fractures commonly seen in children.

2.

Incomplete fracture where one side of the bone breaks and the other side bends; occurs only in children
- A.
  
  Impacted fracture
- B.
  
  Closed
- C.
  
  Comminuted
- D.
  
  Greenstick
- E.
  
  Colles' fracture
Correct Answer
D. Greenstick

Explanation
A greenstick fracture is a type of incomplete fracture that occurs only in children. In this type of fracture, one side of the bone breaks while the other side bends. It is called a "greenstick" fracture because it is similar to when a green stick breaks, where one side splinters and the other side bends. This type of fracture is more common in children because their bones are still developing and are more flexible than adult bones.

3.

One end of the fractured bone is force-fully drived in to the interior of the other.
- A.
  
  Open fracture
- B.
  
  Impacted fracture
- C.
  
  Greenstick
- D.
  
  Pott's fracture
- E.
  
  Colles' fracture
Correct Answer
B. Impacted fracture

Explanation
An impacted fracture occurs when one end of a fractured bone is forcefully driven into the interior of the other. This can happen when a bone is subjected to a great amount of force or pressure, causing the fractured ends to become wedged together. The impacted fracture is characterized by the compression and displacement of the bone fragments, resulting in a stable fracture with minimal movement.

4.

A _______ fracture occurs when a broken piece of the skull is driven inward
- A.
  
  Colles' fracture
- B.
  
  Closed fracture
- C.
  
  Greenstick
- D.
  
  Depressed fracture
- E.
  
  Impacted fracture
Correct Answer
D. Depressed fracture

Explanation
A depressed fracture occurs when a broken piece of the skull is driven inward. This type of fracture is characterized by the displacement of the skull bone, causing it to sink into the brain. It is usually caused by a high-impact force to the head, such as a severe blow or trauma. Depressed fractures can be dangerous as they can cause damage to the brain tissue and blood vessels, leading to potential complications like bleeding, swelling, and neurological deficits. Prompt medical attention is required to assess and treat this type of fracture.

5.

Fracture of the distal end of radius
- A.
  
  Colles' fracture
- B.
  
  Greenstick
- C.
  
  Impacted fracture
- D.
  
  Open fracture
- E.
  
  Pott's fracture
Correct Answer
A. Colles' fracture

Explanation
Colles' fracture refers to a specific type of fracture that occurs at the distal end of the radius bone in the forearm. It is typically caused by a fall onto an outstretched hand, resulting in the distal end of the radius being displaced towards the back of the hand. This fracture is commonly seen in older individuals with osteoporosis. The name "Colles' fracture" is given in honor of Abraham Colles, an Irish surgeon who first described this type of fracture in the early 19th century.
