It ends in a long tendon, which runs behind the lateral malleolus, in a groove common to it and the tendon of the fibularis brevis; the groove is converted into a canal by the superior fibular retinaculum, and the tendons in it are contained in a common mucous sheath.

The tendon changes its direction at two points : first, behind the lateral malleolus; secondly, on the cuboid bone; in both of these situations the tendon is thickened, and, in the latter, a sesamoid fibrocartilage ( sometimes a bone ), is usually developed in its substance.

The "'posterior surface "'is the space included between the postero-lateral and the postero-medial borders; it is continuous below with the triangular area above the articular surface of the lateral malleolus; it is directed backward above, backward and medialward at its middle, directly medialward below.

"' Pott's fracture "', also known as "'Pott's syndrome I "'and "'Dupuytren fracture "', is an archaic term loosely applied to a variety of talus then moves laterally, shearing off the lateral malleolus or, more commonly, breaking the fibula superior to the tibiofibular syndesmosis.
