High-Resolution Ultrasound and MRI for Management of Peroneal Tendon Injuries

Diagnosis of patients with chronic lateral ankle pain, from a sprained ankle for example, needs to include investigation for possible damage to the peroneal tendon complex according to research published in the January-February 2015 issue of the Radiological Society of North America (RSNA) RadioGraphics journal.

Damage to the peroneus brevis or peroneus longus tendons may be a result of trauma, repeated microtrauma from instability, or from existing tendinopathy.

To help orthopedic surgeons with evaluation and diagnosis of peroneal tendon injuries the researchers recommend using high-resolution Magnetic Resonance Imaging (MRI) (1.5-T and 3-T scanners) with dedicated extremity coils, and high-resolution Ultrasound (US), with high-frequency linear transducers, and dynamic imaging.

The combination of MRI scans and high-resolution Ultrasound should allow radiologists to recognize the normal anatomy and pathology of peroneal tendon injuries (partial- and full-thickness tears, subluxation, and dislocation for example) and decide on the best treatment for superior peroneal retinaculum (SPR) and peroneal tendon injuries.
