CAISS Extremity Injuries 5

Question 1

Which of the following best describes the use of the AIS severity score of 3 for extremity injuries?

Accepted Answer

Serious but not life-threatening, hospitalization required

Answer

AIS 3 (serious) indicates significant injury requiring hospitalization but without an immediate threat to life.

Question 2

A closed distal radius fracture (Colles' fracture) in an adult is typically assigned which AIS severity?

Accepted Answer

AIS 2

Answer

A closed distal radius fracture is a moderate injury coded AIS 2, reflecting need for treatment without serious morbidity.

Question 3

In AIS coding, compartment syndrome developing after a tibial fracture is treated as:

Accepted Answer

A complication that elevates the fracture's AIS severity

Answer

Compartment syndrome is considered when selecting the appropriate AIS descriptor, generally elevating the overall severity of the associated fracture.

Question 4

What is the primary purpose of including extremity injuries in the ISS calculation?

Accepted Answer

To quantify overall trauma burden across body regions

Answer

ISS uses AIS scores across body regions to provide a numeric summary of total injury burden that correlates with mortality and morbidity.

Question 5

A patient has an AIS 4 lower extremity injury and an AIS 3 upper extremity injury. These two scores contribute to ISS as:

Accepted Answer

4² + 3² = 25

Answer

Upper and lower extremity are separate AIS body regions, so both scores contribute: 4² + 3² = 16 + 9 = 25.
