Abstract:
Objective To investigate the 3D reconstruction of multislice spiral CT technology applications in the diag-nosis and postoperative ankle fracture assessment. Methods DR using X-ray and 3D reconstruction of multislice spiral CT technique in patients with ankle fractures preoperative examination and classification, for review after observing the quality of reduction and fixation into quality. Results Preoperative DR typing results compare with intraoperative find-ings, PAB, PER, SAB SER type Kappa values were 0.76, 0.80, 0.77, 0.75, had a good consistency . Preoperative CT reconstruction with intraoperative findings result of the comparison , PAB, PER, SAB SER type Kappa values were 1, 0.92, 0.90, 0.90, excellent consistency, CT reconstruction typing and intraoperative findings consistent results. The sensitivity and specificity were far superior to DR. DR and CT reconstruction after treatment in PAB, PER, SER type reset mass were significantly different (P<0.05), CT three reconstruction PER, fixed into the SER type mass was signif-icantly different (P<0.05). Conclusion Spiral CT reconstruction of ankle fracture before surgery and postoperative re-duction treatment, quality assessment and internal fixation into a higher accuracy than the X-ray examination, and more reliable.
