CAISS Anatomical Terminology & Injury Description 2 — Questions and Answers
Question 1: In AIS terminology, what does the term 'contusion' specifically describe?
- A bruise resulting from blunt trauma without skin laceration (Correct answer)
- A complete tear of a ligament
- A fracture with skin penetration
- A compression injury to a nerve
Correct answer: A bruise resulting from blunt trauma without skin laceration
A contusion is a bruise caused by blunt force trauma that damages underlying tissue without breaking the skin.
Question 2: Which anatomical plane divides the body into anterior and posterior sections?
- Sagittal plane
- Transverse plane
- Coronal plane (Correct answer)
- Oblique plane
Correct answer: Coronal plane
The coronal (frontal) plane divides the body into anterior (front) and posterior (back) sections.
Question 3: In AIS coding, the suffix 'S' after a code number indicates what?
- Serious injury
- Skeletal involvement
- Sequelae of injury (Correct answer)
- Superficial wound
Correct answer: Sequelae of injury
In injury coding systems, the 'S' suffix denotes sequelae, meaning the late effects or complications resulting from a prior injury.
Question 4: What is the correct anatomical term for the armpit region?
- Antecubital
- Axillary (Correct answer)
- Brachial
- Cubital
Correct answer: Axillary
The axillary region refers to the armpit, where the arm meets the thorax.
Question 5: When documenting an injury 'distal to the elbow,' where is the injury located?
- Above the elbow, toward the shoulder
- Below the elbow, toward the wrist (Correct answer)
- At the elbow joint itself
- Behind the elbow on the posterior surface
Correct answer: Below the elbow, toward the wrist
Distal means farther from the point of origin or attachment, so distal to the elbow is toward the wrist and hand.
Question 6: Which term best describes an injury where the bone end is driven into an adjacent bone segment?
- Comminuted fracture
- Impacted fracture (Correct answer)
- Greenstick fracture
- Oblique fracture
Correct answer: Impacted fracture
An impacted fracture occurs when bone fragments are driven or compressed into each other, often seen in vertebral compression injuries.
Question 7: In anatomical terminology, 'ipsilateral' refers to injuries occurring on what side?
- The opposite side of the body
- The same side of the body (Correct answer)
- The midline of the body
- The inferior aspect of the body
Correct answer: The same side of the body
Ipsilateral means occurring on the same side of the body, as opposed to contralateral which means opposite side.
