the peripheral process at which terminate the inner surface of the distal (that is, from the trunk) epiphysis of the tibia (the inner malleolus) and the lower, thickened end of the fibula (the outer malleolus). Both malleoli have flat articular surfaces and hold the articular surface (trochlea) of the talus in a fork.
