“…Sonography of normal lateral ligaments shows a band-like structure made up of many fibrillar hyperechoic signals extending on a longitudinal axis plane and an oval shape on short-axis scans. 7,16,17 After sprain, the enlargement, focal defect and abnormal lengthening of a ligament should be seen on ultrasonography and as a bony fragment within ligaments, which were all detected in the present study. 18 In our study, the ability of ultrasonography to depict ATFL and CFL injuries with a sensitivity of 98.9% and 93.8%, respectively, and a specificity of 93.8% and 90.9%, respectively, was comparable to those of MRI.…”

Yi Cheng and Yehua Cai both contributed equally to this article.Objective: The aim of this study was to assess the accuracy of ultrasonography in the diagnosis of chronic lateral ankle ligament injury. Methods: A total of 120 ankles in 120 patients with a clinical suspicion of chronic ankle ligament injury were examined by ultrasonography by using a 5-to 17-MHz linear array transducer before surgery. The results of ultrasonography were compared with the operative findings. Results: There were 18 sprains and 24 partial and 52 complete tears of the anterior talofibular ligament (ATFL); 26 sprains, 27 partial and 12 complete tears of the calcaneofibular ligament (CFL); and 1 complete tear of the posterior talofibular ligament (PTFL) at arthroscopy and operation. Compared with operative findings, the sensitivity, specificity and accuracy of ultrasonography were 98.9%, 96.2% and 84.2%, respectively, for injury of the ATFL and 93.8%, 90.9% and 83.3%, respectively, for injury of the CFL. The PTFL tear was identified by ultrasonography. The accuracy of identification between acute-on-chronic and subacute-chronic patients did not differ. The accuracies of diagnosing three grades of ATFL injuries were almost the same as those of diagnosing CFL injuries. Conclusion: Ultrasonography provides useful information for the evaluation of patients presenting with chronic pain after ankle sprain. Advances in knowledge: Intraoperative findings are the reference standard. We demonstrated that ultrasonography was highly sensitive and specific in detecting chronic lateral ligments injury of the ankle joint.

“…These 2 bony landmarks appear hyperechoic on the ultrasound image and correspond to the anatomical locations of the origin and insertion of the ATFL in this imaging plane. 2,7,10,40 The region between these landmarks is considered the talofibular interval, which the ATFL spans. The talofibular interval was measured on 3 images taken in the neutral ankle position with 0 N of force applied and on 3 images taken with 125 N of force applied.…”

“…Ultrasonography (US) is useful in evaluating the lateral ankle ligaments as it provides high resolution of ligament anatomy and pathology. 6 In addition, as US imaging can be performed dynamically, the integrity of the lateral ankle ligaments can be assessed in real-time under joint stress maneuvers. In cases where joint degeneration has occurred or impingement is suspected clinically, the dynamic nature of US again allows real-time visualization of bony impingement while also permitting correlation to the patient's symptomatology.…”

Objective: The purpose of this case report is to describe the diagnostic value of ultrasonography (US) in a patient with injury to the lateral ligaments of the ankle with concomitant ankle joint osteoarthritis and anterior impingement. Clinical Features: A 28-year-old male had a history of an inversion injury of the left ankle. Diagnostic US of the left ankle using an 8-to 15-MHz linear array transducer demonstrated a full thickness tear of the anterior talofibular ligament, partial thickness tearing of the calcaneofibular ligament, and laxity of the ankle with varus stress testing. In addition, US was able to demonstrate degeneration of the ankle and talonavicular joints and anterior impingement with dorsiflexion. Osteoarthritic changes were confirmed with radiography. Other US findings included remote deltoid ligamentous complex injury, multiple sites of tenosynovitis, and a large ankle joint effusion with synovial hypertrophy and synovitis. Intervention and Outcome: Using US, an accurate diagnosis was established with respect to the pathology and functional impairments of the patient's ankle. Conclusion: This case report exemplifies the value and utility of US in diagnosing derangement in ligamentous, tendinous, articular, and osseous injuries of the ankle.
