“…The accuracy of the routine ankle MRI protocol for diagnosis of acute ATFL injury is still in doubt because of its wide range of specificity (70-97%) and sensitivity (40-95%) [14][15][16][17]. MRI may show detachment, discontinuity, thickening, thinning, contour irregularity of the ligament, a bright rim sign [16] or an associated bony avulsion [18][19][20][21].…”

Magnetic Resonance Accuracy in the Diagnosis of Anterior Talo-Fibular Ligament Acute Injury: A Systematic Review and Meta-Analysis

Background: The studies about injury to the anterior talo-fibular ligament (ATFL) are focused mainly on chronic symptoms and chronic instability, and the literature about the accuracy of magnetic resonance imaging (MRI) in acute injuries is quite lacking. Methods: This systematic review with meta-analysis analyzes the diagnostic accuracy of MRI on acute ATFL injury. Relative studies were retrieved after searching three databases (MEDLINE, SCOPUS, and Cochrane Central Register of Controlled Trails). Eligible studies were summarized. The quality of the included articles was assessed using the revised Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Data were extracted to calculate pooled sensitivity and specificity of MRI. Results: Seven studies met our inclusion and exclusion criteria. For MRI, the pooled sensitivities and specificity in diagnosing acute ATFL injury were respectively 1.0 (95% CI: 0.58–1) and 0.9 (95% CI: 0.79–0.96). Pooled LR+ and LR− were respectively 10.4 (95% CI: 4.6–23) and 0 (95% CI: 0–0.82). Conclusion: This systematic review with meta-analysis investigated the accuracy of imaging for the diagnosis of acute ATFL injury. Our results demonstrated that MRI shows high diagnostic accuracy in the diagnosis of acute ATFL lesions. These results suggest that routine MRI in the case of suspected ATFL acute injury may be clinically useful, although this is not done in clinical practice due probably to high cost.

“…Chronic ligament injury usually presents with morphological changes on MRI such as heterogeneous, intra-substance signals, wavy contour, thinning or elongation, and poor visualization or absence of ligament ( Figure 5). The surrounding fatty tissue may show fibrosis with medium-signal-intensity or may show a synovitis with a high-signal-intensity [40].…”

Ankle sprains involve up to 30% of all sport injuries. About 30% of patients may develop chronic ankle instability (CAI), which significantly limits their professional or recreational activities. The diagnosis of CAI relies on the understanding of anatomy and a thorough assessment of the patient. Imaging studies, including plain radiographs, sonography, MRI, and arthroscopic examinations, are beneficial in evaluating the extent and structures involved. Once conservative treatment has failed, surgery is indicated to restore ankle joint stability. Suture repair is sufficient, whether open or arthroscopically, if the remnant ligament quality is acceptable. Anatomical graft reconstruction is used for poor remnant quality or revision.

“…Loaded and unloaded plain-film stress radiographic imaging can speculate STJ dysfunction, where larger foot posture differences correspond with clinical instability [ 13 ]. Diagnostic ultrasound, computerized tomography, and magnetic resonance imaging can provide important information concerning anatomical tissue integrity [ 13 – 15 ]. However, these provide limited objective STJ mobility data, as well as mechanical tissue properties (elasticity, stiffness or strain response).…”

The relationship between measures of foot mobility and subtalar joint stiffness using vibration energy with color Doppler imaging-A clinical proof-of-concept validation study

et al. 2020

View full text Add to dashboard Cite

Introduction Subtalar joint (STJ) dysfunction can contribute to movement disturbances. Vibration energy with color Doppler imaging (VECDI) may be useful for detecting STJ stiffness changes. Objectives (1) Support proof-of-concept that VECDI could detect STJ stiffness differences; (2) Establish STJ stiffness range in asymptomatic volunteers; (3) Examine relationships between STJ stiffness and foot mobility; and (4) Assess VECDI precision and reliability for examining STJ stiffness. Methods After establishing cadaveric testing model proof-of-concept, STJ stiffness (threshold units, ΔTU), ankle complex passive range-of-motion (PROM) and midfoot-width-difference (MFWDiff) data were collected in 28 asymptomatic subjects in vivo. Three reliability measurements were collected per variable; Rater-1 collected on all subjects and rater-2 on the first ten subjects. Subjects were classified into three STJ stiffness groups. Results Cadaveric VECDI measurement intra-rater reliability was 0.80. A significantly lower STJ ΔTU (p = .002) and ankle complex PROM (p < .001) was observed during the screw fixation versus normal condition. A fair correlation (r = 0.660) was observed between cadaveric ΔTU
