Peroneal Tendon Pathology eMedicine Orthopedics

Description: Problems may arise in either of the tendons alone, or both may be involved with subluxation. The hallmark of disorders of the peroneal tendons is laterally based ankle or foot pain. Whether the problem is tendinous degeneration or subluxation, the clinical manifestation is pain. With time, loss of eversion strength may occur.
Problems arising with the peroneus longus include tenosynovitis and tendinous disruption (acute or chronic). The os peroneum may be involved with the degenerative process or as a singular disorder and can be fractured or fragmented. Longitudinal tears of the peroneus longus are uncommon but have been reported.
Longitudinal tears of the tendon are the most common problem seen with the peroneus brevis tendon. These may be single or multiple. Tendinitis and tenosynovitis also may occur.
Subluxation of both peroneal tendons may occur following an acute traumatic episode or may be of a more chronic nature.
