The Orthobiologic Institute (TOBI) Faculty Thomas O. Clanton Publishes New Study in Knee Surgery, Sports Traumatology, Arthroscopy:

Thomas O. Clanton, The Orthobiologic Institute (TOBI) Alumni, recently published a new article in Knee Surgery, Sports Traumatology, Arthroscopy titled “Magnetic resonance imaging characterization of individual ankle syndesmosis structures in asymptomatic and surgically treated cohorts.” The study describes the 3.0-T MRI characteristics of distal tibiofibular syndesmosis in both symptomatic and asymptomatic patients.


Ten volunteers were initially imaged to characterize the syndesmotic anatomy of asymptomatic individuals. Subsequently, a series of 21 consecutive patients received a pre-operative 3.0-T ankle MRI followed by arthroscopic evaluation for presumptive syndesmotic injury. Pre-operative images were prospectively collected and findings were correlated with arthroscopy to determine diagnostic accuracy.


The study revealed that pre-operative MRI strongly correlated with findings on arthroscopy. Syndesmotic ligament tear was appropriately diagnosed on MRI with excellent results. The sensitivity, specificity, PPV, NPV, and accuracy for diagnosing anterior inferior tibiofibular ligament disruption were 87.5, 100, 100, 71.4, 90.5 %, respectively; N/A, 95.2, 0.0, 100, 95.2 % for posterior inferior tibiofibular ligament; and 66.7, 86.7, 66.7, 86.7, 81.0 % for interosseous tibiofibular ligament.


These results demonstrate that 3.0-T MRI serves as an excellent diagnostic tool for identifying syndesmotic ligament disruption as it allows for the visualization of each syndesmotic structure. Thus, a 3.0-T MRI of ankle facilitates the clinical detection of ligamentous injuries. It is important to implement optimal high-field MRI sequences into a standard clinical ankle MRI exam as it aids in the diagnosis of syndesmotic injuries, improves pre-operative planning, and supplements surgical repair by providing details involving the integrity of structures which are not easily assessed on physical exam or other radiographic measures.
