Abstract

Tenosynovitis of the tendon of peroneus longus has rarely been described in the literature (Aberle-Horstenegg, 1932; Burman and Lapidus, 1931). This is a report on the condition in two athletes and in one of whom the os peroneum was absent on the side of the tenosynovitis. It emphasises the importance of a detailed review of athletes' training patterns when assessing their injuries.
