复合指深屈肌有来自尺神经（UN）和骨间前神经（AIN）的双重神经供应，但关于这2条神经的区域的解剖数据有限。在这项研究中，肌肉从20具尸体前臂显微解剖。运动神经被跟踪到它们在单个肌腹上的终止，并绘制神经支配域。在75%的病例中，AIN供应食指和中指，而UN供应中指、无名指和小指;因此，中指具有双重神经支配。在20%的病例中，AIN位于食指和中指，UN位于无名指和小指。在5%的病例中，AIN位于食指，UN位于中指、无名指和小指。将运动进入点标准化为前臂长度。联合国和阿拉伯联合酋长国分支机构的切入点为15%。和30%的前臂长度，分别在内上髁远端。（J Hand Surg 1999;24A：700-703.版权所有（C）1999美国手外科学会。
The composite flexor digitorum profundus muscle has a dual nerve supply from the ulnar nerve (UN) and the anterior interosseous nerve (AIN) but anatomic data regarding the territories of these 2 nerves are limited. In this study, muscles from 20 cadaver forearms were dissected microscopically. The motor nerves were followed to their terminations on individual muscle bellies and the innervation domains mapped. In 75% of cases the AIN supplied the index and middle fingers and the UN supplied the middle, ring, and little fingers; thus, the middle finger had dual innervation. In 20% of cases the AIN went to the index and middle fingers and the UN went to the ring and little fingers. In 5% of cases the AIN went to the index finger and the UN went to the middle, ring, and little fingers. The motor entry points were normalized to the forearm length. The entry points of the UN and AIN branches were at 15%. and 30% of forearm length, respectively, distal to the medial epicondyle. (J Hand Surg 1999;24A:700-703.
