We report a new muscular variation in humans. It consisted of a biceps brachii muscle attached to the extensor carpi radialis brevis muscle by means of an accessory fasciculus. It was a trapezoid tendinous connection band that arose from the terminal tendon of the biceps brachii muscle and ended in the internal margin of the extensor carpi radialis brevis muscle. This intermuscular connection band was the external slip of the insertion tendon of the biceps brachii muscle, which was also attached by means of two other fascicles to the radial tuberosity (intermediate slip) and the flexor digitorum superficialis muscle (internal slip). This variation was observed in only one of the sixty upper limbs examined.
我们报告了一种人类新的肌肉变异。它由一条肱二头肌通过一条副束附着于桡侧腕短伸肌组成。它是一个梯形腱性连接带，起自肱二头肌的终腱，止于桡侧腕短伸肌的内侧缘。这条肌间连接带是肱二头肌止腱的外侧束，肱二头肌还通过另外两条束分别附着于桡骨粗隆（中间束）和指浅屈肌（内侧束）。在所检查的60条上肢中，仅在1例中观察到这种变异。
