Abstract
Peroneal subluxation is relatively rare and commonly misdiagnosed as an ankle sprain. Due to its rarity, the incidence of subluxation is unknown, but it has been seen most often in young adults. Peroneal subluxation in pediatric patients is very rare and bilateral subluxation is even rarer.

Summary
Bilateral SPR repair procedures were found to be effective in this pediatric case of acquired bilateral peroneal tendon subluxation following a bilateral trauma with no known risk factors. The red arrows demonstrate the large amount of fluid signal intensity about the peroneus longus and brevis tendons indicative of tenosynovitis These injuries are often initially handled with conservative treatment, such as taping or compressive bandages, conservative treatment alone has an overall failure rate of 50-76% for adults, with no reported literature on pediatric patients [10]. Adult patients that are treated surgically with both SPR repair and with peroneal tendon groove deepening have a higher rate of returning to sports when compared to patients that only received an SPR repair [12] In this case, conservative therapy on the left ankle failed to prevent subluxation leading to surgical intervention. In similar presentations we recommend consideration be given to this treatment course
