Abstract
Purpose
The radiological examination including plain radiography, CT and MRI are critical to assess the severity of the instability, to diagnose the fracture type and to select the appropriate treatment strategy for the thoracic and lumbar vertebral fractures. The aim of this prospective observational study was to investigate the effect of magnetic resonance imaging (MRI) on decision making for the diagnosis and treatment of acute thoracic and lumbar vertebral fractures.
Methods
Consecutive 180 patients with acute thoracic and/or lumbar vertebral fractures were included in the study. The fracture pattern was evaluated by using initial radiographs, computed tomography (CT) and MRI within 24 h of trauma. Fractures were classified according to AO classification before and after MRI. TLICS classification was also used to decide treatment plan. MRI findings were compared to surgical findings in the surgically treated patients.
Results
A significant moderate agreement was found between Xray + CT and post-MRI classifications for all fracture types (Kappa = 0.511; p < 0.001). In 101 patients with new findings on MRI, a significant moderate correlation was observed between Xray + CT and post-MRI classifications in the fracture re-classification (Kappa = 0.441, p < 0.001). There was a significant change in the treatment plan of patients with new findings on MRI according to Xray + CT (p < 0.0001). After MRI evaluation, the treatment plan changed in favor of surgery in 33.9% of patients who were scheduled for conservative treatment according to Xray + CT (p < 0.0001).
Conclusion
Since MRI assessment of acute thoracic and/or lumbar injuries has led to a remarkable treatment change decision that confirms intraoperative findings of the patients who were decided to undergo surgery, MRI should be obtained in thoracic and lumbar vertebral fractures, regardless of the CT and plain radiographic findings.
