An interesting case of peculiarity of the distal attachment of the three fibular muscles is reported in the left foot of a male adult cadaver of Indian origin. The fibularis brevis, just inferior to the fibular malleolus, gave off an additional slender tendon anteromedial to its main tendon. This was attached to the dorsal digital expansion of the little toe while its main tendon was inserted to the customary bone. The tendon of fibularis longus on the plantar aspect just medial to the cuboid tunnel received a prominent slip of attachment of the tendon of tibialis posterior. The fibularis tertius had two parallel-running tendons attached to the bases of the fourth metatarsal and the fourth and fifth metatarsals respectively. The combined variation of the three fibulares in a single foot has not been reported previously. The more distal attachment of the fibularis brevis in this case is a regression in evolution. Weakness of both the fibularis brevis and fibularis longus is found in pes cavovarus. The former can be used as a rotational graft in soft tissue loss of the leg.
据报道，在一具印度成年男性尸体的左足上，发现了三块腓骨肌远端附着异常的有趣病例。腓骨短肌在腓骨外踝下方，于其主要肌腱的前内侧发出一条额外的细长肌腱。该肌腱附着于小趾的背侧指背腱膜，而其主要肌腱则插入到通常的骨骼部位。腓骨长肌肌腱在足底，恰好在骰骨管内侧，接受了胫后肌腱的一条明显附着束。腓骨第三肌有两条平行走行的肌腱，分别附着于第四跖骨基部以及第四和第五跖骨基部。此前尚未报道过单足中三块腓骨肌的这种联合变异情况。在本病例中，腓骨短肌更靠远端的附着是一种进化上的退化。高弓足中可发现腓骨短肌和腓骨长肌均无力。前者可用于腿部软组织缺损的旋转移植。
