Prevertebral soft tissue changes in cervical spine injury

Area of Science:

• Radiology
• Orthopedics
• Trauma Surgery

Background:

• Cervical spine injury diagnosis presents challenges in primary radiological assessment.
• Prevertebral soft tissue (PST) alterations are key indicators of potential cervical spine fractures.
• Existing literature shows variability in normal PST width values and incidence of widening with injury.

Purpose of the Study:

• To investigate the diagnostic utility of prevertebral soft tissue widening in cervical spine injuries.
• To analyze factors influencing normal PST width, including measurement level, spinal posture, and patient age.
• To clarify the incidence and significance of PST widening in various cervical spine injury patterns.

Main Methods:

• Retrospective analysis of radiological data from 165 patients with confirmed cervical spine injuries.
• Comparison with a control group of 70 patients without cervical spine injury.
• Inclusion of flexion-extension radiograms from the control group to assess positional effects on PST width.

Main Results:

• Prevertebral soft tissue widening is a significant radiological sign associated with cervical spine injuries.
• Normal PST width varies based on cervical spine level, patient age, and spinal posture.
• PST widening is observed in injuries affecting anterior, upper, and posterior cervical spine structures.

Conclusions:

• Accurate measurement and interpretation of prevertebral soft tissue width can enhance cervical spine fracture diagnosis.
• Understanding the influencing factors of PST width is crucial for reliable radiological assessment.
• This study provides a comprehensive analysis to improve the diagnostic accuracy of cervical spine trauma imaging.
