Summary
Accurate syndesmotic reduction is crucial for ankle fracture outcomes. Advanced imaging did not improve malreduction rates compared to standard fluoroscopy in this study.
Area of Science:
- Orthopedic Surgery
- Radiology
- Trauma Care
Background:
- Syndesmotic reduction quality impacts ankle fracture outcomes.
- Syndesmotic injuries require precise surgical correction for optimal results.
Purpose of the Study:
- To compare the accuracy of intraoperative syndesmotic reduction using standard fluoroscopy versus three-dimensional (3D) Iso-C3D imaging.
- To evaluate the effectiveness of advanced imaging in improving syndesmotic reduction quality.
Main Methods:
- Prospective review of 36 patients with syndesmotic diastasis undergoing fixation.
- Comparison of reduction accuracy between Center A (intraoperative CT) and Center B (standard fluoroscopy).
- Assessment of anterior/posterior fibular distance and anterior translation post-surgery.
Main Results:
- High rates of malreduction observed in both standard fluoroscopy and 3D imaging groups.
- No significant difference in anterior translation or anterior fibular distance malreductions between centers.
- Significant difference in posterior fibular distance malreductions (6% Center A vs. 40% Center B, p=0.03).
Conclusions:
- Advanced intraoperative imaging (Iso-C3D) did not reduce syndesmotic malreduction rates.
- High rates of malreduction persist despite advanced imaging techniques.
- Standard fluoroscopy may be sufficient for assessing syndesmotic reduction quality.
