The fibularis tertius (FT) is one of three muscles which constitute the anterior compartment of the leg. The anatomical variants of this muscle usually pertain to its origins, number of final tendons or points and shapes of insertions. In this case, it had an additional slip (AS) which originated from the same area as the main muscle belly and after descending along the extensor digitorum longus (EDL) it fused with one of its main tendons. The main muscle belly and its tendon, in its usual manner, reached the proximal dorsal surface of the fifth metatarsal bone. To our knowledge, no similar case had been described before. This case reveals that human anatomy, though it may be thoroughly described, can still be a surprise and a vast field for new discoveries. Knowledge about these variants is important from both the scientific and clinical points of view.
第三腓骨肌（FT）是构成小腿前侧肌群的三块肌肉之一。该肌肉的解剖变异通常与其起点、终腱数量或附着点及形状有关。在此病例中，它有一个额外的肌束（AS），该肌束与主要肌腹起于同一区域，沿趾长伸肌（EDL）下行后，与该肌的一条主要肌腱融合。主要肌腹及其肌腱以其通常的方式到达第五跖骨近端背侧表面。据我们所知，此前尚未有类似病例的描述。该病例表明，人体解剖学尽管可能已被详尽描述，但仍可能带来惊喜，且是一个有待新发现的广阔领域。从科学和临床角度来看，了解这些变异都很重要。
