Definition/Description[edit | edit source]
Subluxation or dislocation of the peroneal tendons is a disorder involving an elongation, a tear or an avulsion of the superior peroneal retinaculum [1]. There can be also subluxation of the tendons with an intact SPR (intrasheath subluxation) [2].
Clinically Relevant Anatomy[edit | edit source]
Anatomy of the Mm. peronei
The M. peroneus brevis and M. peroneus longus are contained in the retromalleolar sulcus on the fibula. The depth of the sulcus is variable and has been noted to be absent or convex [7]. The tendons are stabilized by a superior peroneal retinaculum. The SPR is formed by thickening of the superficial aponeurosis. A small fibrous ridge is occasionally seen originating from the distal fibula close to the origin of the SPR and increases the depth of the fibular groove. Distal to the fibula is the inferior peroneal retinaculum, which covers the tendons for about 2 to 3 cm distal to the tip of the fibula [3].
