Spine Injuries Flashcards

In pediatric patients under age 8, spinal cord injury without radiographic abnormality (SCIWORA) occurs more frequently than in adults primarily because:

Answer: The pediatric spine is more elastic, allowing cord injury without bony disruption

The pediatric spine's hypermobility and elasticity allow significant cord stretch and injury without detectable fracture or dislocation on imaging.

When coding a hangman's fracture (traumatic spondylolisthesis of C2), the AIS coder must determine severity primarily based on:

Answer: Degree of displacement and presence of neurological deficit

Fracture displacement and neurological status are the primary determinants of AIS severity for C2 traumatic spondylolisthesis.

The AAAM AIS 2005 Spine chapter codes injuries with cord contusion and complete neurological deficit at which level?

Answer: AIS 6

Complete neurological deficit from cord injury represents maximum neurological devastation and is coded AIS 6 in the AIS 2005 spine chapter.

A patient involved in a rear-end collision presents with neck pain, muscle spasm, and limited range of motion but no fracture on imaging. AIS coding of this soft-tissue cervical injury is most likely:

Answer: AIS 1

Soft-tissue cervical sprains/strains (whiplash-associated disorders Grade I-II) without fracture or neurological deficit are coded AIS 1 in the spine region.

In the context of CAISS certification, 'abbreviated' in the Abbreviated Injury Scale primarily refers to:

Answer: The scale being a short proxy for comprehensive injury description

The AIS provides a brief, standardized severity rating as a proxy for detailed clinical description, enabling efficient epidemiological data collection.

Which of the following best describes an AIS spine code of '650202.3' in AIS 2005 format?

Answer: Both A and C are correct

In AIS pre-dot code format, digits encode body region, chapter, and specific injury descriptor, while the post-decimal digit is the severity score.

A trauma registry receives a case coded with two spine injuries: AIS 3 (T8 burst fracture) and AIS 4 (T8 fracture with incomplete paraplegia). Which coding principle applies?

Answer: Only one code for the same injury location should be used — select the more severe descriptor

AIS coding rules require selecting the single most accurate and severe code that best characterizes an injury at a given location, avoiding duplicate coding of the same injury.
