Placement of markers. This accessory tendon of fibularis longus muscle also received some muscle slips of fibularis brevis muscle on the posterior aspect (fig.1). The tendon of the muscle descends down the leg, and runs posterior to the lateral malleolus along with the tendon of the peroneus (fibularis) brevis. The tendon of fibularis brevis muscle displayed usual disposition and insertion into base of fifth metatarsal bone. The difference between the two is that the peroneus brevis starts lower down in the leg, while the peroneus longus starts higher up in the leg. The fibularis quartus muscle is described as a variation of the fibularis brevis muscle in the majority of the authors. of fibularis longus and brevis muscles in the middle third of leg and this tendon joined the main tendon of fibularis longus muscle obliquely, 2.3 cm proximal to the tip of late-ral malleolous. the peroneal longus tendon passes down the leg superficial to the peroneus brevis muscle and does not touch the lateral malleolus due to the intervening brevis tendon.
