ABSTRACT
OBJECTIVES:
To explore the diagnostic value of ultrasonography for injuries of anterior talofibular ligament (ATFL) and anterior inferior tibiofibular ligament distal fascicle (ATiFL-DF) in patients with ankle fractures.METHODS:
Clinical data of 51 patients with ankle fractures who were clinically suspected of ligament injuries and underwent ankle ultrasonography examination and arthroscopy in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from April 2019 to March 2023 were retrospectively analyzed. Using arthroscopic findings as the gold standard, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ultrasonography in diagnosing ATFL and ATiFL-DF injuries were evaluated; and Kappa consistency test was further performed.RESULTS:
The sensitivity and specificity of ultrasonography in diagnosis of ATFL injury were 100.0% and 92.3%, with the PPV of 92.6% and NPV of 100.0%. Ultrasonography findings exhibited excellent concordance with arthroscopic results (kappa=0.849). The sensitivity and specificity of ultrasonography in diagnosis of ATiFL-DF injury was 86.7% and 33.3%, with the PPV of 90.7% and NPV of 25.0%. But the consistence between ultrasonography and arthroscopic results was poor (kappa=0.168).CONCLUSIONS:
Ultrasonography is a reliable diagnostic modality for assessing injuries to the ATFL in patients with ankle fractures; however, its specificity is limited when evaluating injuries to the ATiFL-DF. Therefore, ankle arthroscopy is necessary for ankle fracture patients with negative findings of ATiFL-DF in ultrasonography.
