subluxing peroneal tendons

subluxing peroneal tendons

acute or chronic, traumatic, anterolateral displacement of peroneal tendons (longus and brevis) within the common synovial sheath ± rupture of overlying retinaculum and/or avulsion ('fleck') fracture at retinacular insertion on to lateral malleolus; injury extent depends on applied force and foot/limb position at the time of injury; acute presentation is treated with RICE(P) therapy and non-weight-bearing immobilization; chronic injury may respond to bespoke orthoses, or may require surgical correction (see superior peroneal retinaculum rupture)

Geppert also noted that lateral ankle instability was associated with several peroneal pathologies, including superior peroneal retinaculum laxity, subluxing peroneal tendons, and splits of the peroneus brevis tendon.
