Pelvic radiography in ATLS algorithms: A diminishing role?

Area of Science:

• Trauma Imaging
• Emergency Medicine
• Radiology

Background:

• Pelvic X-ray is standard in polytrauma assessment per Advanced Trauma Life Support (ATLS) guidelines.
• Pelvic CT is the definitive imaging modality for diagnosing pelvic fractures.
• This study evaluated a modified ATLS protocol omitting pelvic X-ray for stable patients.

Purpose of the Study:

• To assess the safety and efficacy of a modified ATLS algorithm.
• To confirm the utility of prioritizing CT scans over X-rays for stable pelvic trauma patients.

Main Methods:

• Retrospective analysis of polytraumatized patients (n=452) between July 2004 and January 2006.
• Inclusion criteria: blunt abdominal trauma, hemodynamic stability, clinically stable pelvis.
• Exclusion criteria: patients requiring immediate intervention due to instability.

Main Results:

• 91 patients met inclusion criteria; 75% had both X-ray and CT, the rest had CT only.
• Pelvic X-ray sensitivity was 67% (3/4 missed fractures on X-ray).
• No false positives on X-ray; no immediate interventions were needed for diagnosed fractures.

Conclusions:

• Pelvic X-ray sensitivity is limited (67%) in stable polytrauma patients.
• Omitting pelvic X-ray in favor of CT is safe and effective for stable patients.
• The modified ATLS algorithm is supported; a randomized trial is recommended.
