The double tendon of extensor digitorum longus (EDL) muscle was observed on the left leg of a 80-year-old male cadaver.
A male cadaver 80 years old was subjected to routine anatomical dissection for research and teaching purposes.
The main tendon of the EDL muscle started just at the end of the muscle belly. However, the accessory tendon started at the tendinous end of the muscle as a continuation of the muscle. The main and accessory tendons split into two more slips after passing through the same tunnel below the extensor retinaculum. There was also difference on ending of the tendon slips of EDL muscle. The main tendon divided into two tendinous slips on the dorsum of the foot attached to the second and third toes. The accessory tendon divided into two tendinous slips on the dorsum of the foot attached to the fourth and the fifth toes.
Knowledge of the tendons and anatomical differences of this muscle is important for surgeons in interventional procedures involving the dorsum of the foot.
在一位 80 岁男性尸体的左腿上观察到伸趾长肌（EDL）的双肌腱。
对一位 80 岁男性尸体进行常规解剖，用于研究和教学目的。
EDL 肌的主肌腱起始于肌腹的末端。然而，副肌腱起始于肌腱的末端，是肌肉的延续。主肌腱和副肌腱在穿过伸肌支持带下方的同一隧道后分成两个更多的分支。EDL 肌的肌腱分支在终点也存在差异。主肌腱在足背分为两个肌腱分支，分别附着于第二和第三脚趾。副肌腱在足背分为两个肌腱分支，分别附着于第四和第五脚趾。
了解该肌肉的肌腱和解剖差异对涉及足背的介入手术的外科医生非常重要。
