“…One cause of variability in ankle stress radiographs may be unidentified determinants. A previous study reported that females showed a 1.5 ° larger tibiotalar tilt angle than males, and the angle decreased 0.05 ° per 1-year increase in age [25]. However, this study did not consider the influence of the bony configuration of the ankle.…”

“…On ankle MRI, ATFL was assessed on axial images, and CFL, posterior talofibular ligaments (PTFL), and deltoid ligaments were evaluated on coronal images. Ligament injuries were classified as intact, partial injury, or complete injury [25]. The presence of ankle joint effusion was also recorded.…”

“…Therefore, both MRI and ankle stress radiographs are generally performed for the preoperative evaluation of ankle instability, although ankle stress radiograph is an indirect and 2-dimensional examination. However, only a few studies have been conducted on the relationship between the degree of ligament injury and laxity on ankle stress radiographs [2,25]. A previous study reported that isolated anterior tibiofibular ligament (ATFL) injury caused only small laxity changes, but a pronounced increase in laxity was observed after a combined calcaneofibular ligament (CFL) and ATFL injury [2].…”

“…Patients at least 20 years old who underwent ankle MRI and radiography in the AP view, AP varus stress view, lateral view, anterior drawer lateral view, and mortise view were included. The exclusion criteria were as follows: (1) acute pain following less than 6 weeks of ankle inversion injury [25]; (2) conditions that could affect normal ankle anatomy such as fracture, os subfibulare, congenital anomaly, tumor, or previous ankle surgeries; and (3) inadequate radiographs that showed more than 3 mm of superimposition of the talar trochlear surface on the lateral ankle view. To compare the measurements on radiographs in ankle instability patients, 274 consecutive patients who were diagnosed with lateral malleolar fracture in our institution between May 2003 and November 2014 were screened.…”

“…Several factors could affect ankle stress radiographs in patients with lateral ankle instability, such as age and sex, in addition to ligament injury on MRI [25]. Therefore, we performed this study to investigate the influence of the relationship between bone morphology and the injured ligament of the ankle on imaging studies and laxity of the ankle on ankle stress radiographs in patients evaluated for lateral ankle instability.…”

This study aimed to investigate the relationship between bone morphology and injured ligaments on imaging studies and laxity on ankle stress radiographs in patients with lateral ankle instability. In total, 115 patients who had undergone ankle MRI, ankle radiography, and stress radiography were included. Distal tibial articular surface angle, bimalleolar tilt, medial and lateral malleolar relative length, medial malleolar slip angle, anterior inclination of the tibia, and fibular position were measured on ankle radiographs. Tibiotalar tilt angle and anterior translation of the talus were measured on ankle stress radiographs. Degree of ligament injury was evaluated on ankle MRIs. Multiple regression analysis was performed using the following independent variables: age, sex, and factors significantly associated with ankle stress view on univariate linear regression analysis. Age (p=0.041), sex (p=0.014), degree of anterior talofibular ligament injury (p<0.001), and bimalleolar tilt (p=0.016) were correlated with tibiotalar tilt angle. Fibular position and degree of posterior talofibular ligament injury were factors significantly related to anterior translation of the talus. Differences in patient characteristics might predispose ankle stress radiograph results. Comparison of both ankles on stress radiographs is superior to applying fixed numerical values to the injured side in order to reduce the influence of patient factors.

Purpose To give a systematic overview of current diagnostic imaging options and surgical treatment for chronic subtalar joint instability. Methods A systematic literature search across the following sources was performed: PubMed, ScienceDirect, and Springer-Link. Twenty-three imaging studies and 19 outcome studies were included. The Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS 2) tool was used to assess the methodologic quality of the imaging articles, while the modified Coleman Score was used to assess the methodologic quality of the outcome studies. Results Conventional radiographs were most frequently used to assess chronic subtalar joint instability. Talar tilt, anterior talar translation, and subtalar tilt were the three most commonly used measurement methods. Surgery often included calcaneofibular ligament reconstruction. Conclusion Current imaging options do not reliably predict subtalar joint instability. Distinction between chronic lateral ankle instability and subtalar joint instability remains challenging. Recognition of subtalar joint instability as an identifiable and treatable cause of ankle pain requires vigilant clinical investigation.

Relationship between stress ankle radiographs and injured ligaments on MRI

Abstract: ATFL injury and PTFL injury on MRI significantly affected tibiotalar tilt angle and anterior drawer on stress radiographs. Other factors, such as age and gender, need to be considered in evaluating radiographic lateral ankle instability.
