Injury of the superior peroneal retinaculum (SPR) in a 46-year-old woman presenting with pain and snapping sensation over the lateral malle- olus 3 months after injury. Axial fat-suppressed T2-weighted magnetic reso- nance image of the ankle demonstrates stripping of SPR (white arrowheads) and anterolateral subluxation of peroneus longus tendon. Note a fibrous ridge at the expected fibular attachment of SPR (black arrowhead). Peroneus brevis tendon is located at the lateral aspect of the retromalleolar groove
