“…The present study found MRI to have 100% sensitivity and specificity in detecting peroneus brevis tears. Previous studies showed MRI to have sensitivities in the range of 44-56% and specificities in the range of 50-99% in detecting peroneus brevis tears (Table 2) [14,16,17,24]. Our findings may have differed from those of prior studies for several reasons.…”

“…Previous studies have found MRI has 50% sensitivity and 96% specificity in diagnosing tears of the peroneus longus [17]. Another study found MRI to be 67% sensitive and 90% specific in identifying partial peroneus longus tendon tears, and 16.7% sensitive and 91.9% specific in diagnosing longitudinal split tears of the peroneus longus tendon [24]. In a prospective study of ankle tendon tears, US was found to be 75% sensitive and 100% specific with just three surgically proven peroneus longus tendon tears [20].…”

“…Peroneus brevis tendon tears are a common cause of lateral ankle pain with longitudinal split tears occurring most frequently [5,23]. While these types of tears may be seen in any age group, they often result from degeneration or repetitive microtrauma with subsequent tendon thinning, which progresses to a tear propagating from the level of the retromalleolar groove [24]. Less commonly, peroneus brevis tears result from acute athletic injuries and contribute to chronic lateral ankle instability [25,26].…”

Suspected peroneal tendinopathy, tears, and subluxation are often confirmed preoperatively using magnetic resonance imaging (MRI) or diagnostic ultrasound (US). No study has directly compared the accuracy of these tests for the diagnosis of peroneal tendon pathology. The purpose of this study is to directly compare MRI and US to intraoperative findings in patients who underwent surgery for suspected peroneal pathology to determine the imaging diagnostic accuracy. Operative records and diagnostic images for 21 consecutive patients who had both MRI and US prior to surgery for suspected peroneal tendinopathy, tears, or subluxation were retrospectively reviewed. The results of this review are compared with the intraoperative findings to yield the sensitivity and specificity for each imaging modality. For the diagnosis of peroneal tendon tears, US was found to have a sensitivity of 88% and specificity of 100%, compared to 100% sensitivity and specificity for MRI. In the diagnosis of peroneal tendinopathy, both US and MRI had a sensitivity and specificity of 100%. In diagnosing peroneal subluxation, US was 100% sensitive compared to 66% for MRI, and both were 100% specific. In conclusion, US was found to be more effective in diagnosing peroneal subluxation and MRI was slightly more accurate in the diagnosis of peroneal tendon tears.
