This anatomical study of 40 upper limbs from cadavers investigated the branching pattern of the anterior interosseous nerve in its distal part using the operating microscope. An articular branch to the wrist joint and/or the distal radioulnar joint was only found in seven of the 40 specimens and was always a small terminal continuation of the anterior interosseous nerve after the nerve had passed through the pronator quadratus and innervated it. Therefore, we do not recommend division of the anterior interosseous nerve from the dorsal approach through the interosseous membrane before it gives off its muscular branches to the pronator quadratus. This risks damage of the innervation of this muscle of importance for initiation of hand pronation.
这项对40具尸体上肢进行的解剖学研究，使用手术显微镜研究了骨间前神经远端部分的分支模式。在40个标本中，仅在7个标本中发现了一条至腕关节和/或桡尺远侧关节的关节支，并且它总是在骨间前神经穿过旋前方肌并支配该肌之后，作为骨间前神经的一个小终末延续支。因此，我们不建议在骨间前神经发出至旋前方肌的肌支之前，经骨间膜从背侧入路切断骨间前神经。这有损伤这块对启动手部旋前很重要的肌肉的神经支配的风险。
