Summary
Bedside fluoroscopy by emergency physicians showed moderate accuracy (0.85) for diagnosing extremity fractures. However, its low sensitivity (0.70) means it is not reliable for screening simple fractures in the emergency department.
Area of Science:
- Emergency Medicine
- Radiology
- Orthopedic Surgery
Background:
- Portable fluoroscopy is frequently used by orthopedic surgeons for fracture management.
- The utility of bedside fluoroscopy by emergency department (ED) physicians for initial trauma screening is less understood.
- Accurate and timely diagnosis of extremity trauma is crucial in the ED setting.
Purpose of the Study:
- To evaluate the diagnostic accuracy of bedside fluoroscopy performed by ED physicians.
- To determine the sensitivity and specificity of this imaging modality for detecting simple extremity trauma.
- To assess the reliability of fluoroscopy as a screening tool for distal extremity fractures.
Main Methods:
- Prospective evaluation of adult patients with isolated distal extremity injuries over 6 months.
- ED physicians performed independent bedside fluoroscopy, capturing real-time images and documenting interpretations.
- Fluoroscopic findings were compared against subsequent standard diagnostic radiographs and radiologists' final reports.
Main Results:
- Ninety-two patients with 108 extremity injuries were analyzed.
- Fluoroscopy diagnosed fractures with a sensitivity of 0.70 and a specificity of 0.93.
- Overall diagnostic accuracy was 0.85, with 11 false-negative reports identified.
Conclusions:
- Bedside fluoroscopy performed by ED physicians demonstrates moderate diagnostic accuracy for extremity trauma.
- The sensitivity of fluoroscopy is insufficient for reliably screening simple extremity fractures in the ED.
- Further investigation may be needed to optimize the role of fluoroscopy in trauma assessment.
