Within a period of five months, in eleven of all the cases examined, the author found the M. abductor digiti minimi longus as was described by Frohse and Fränkel in 1908. It ran from the fascia antebrachii through the Canal de Guyon to the hypothenar muscle mass. Vascularization and innervation were by the ulnar artery and nerve. This muscle must be assigned to the hypothenar muscular system, while a variation of the palmaris longus muscle, which is found in the same region and frequently described in the literature is supplied by the median nerve. Further, the literature has held this muscle to be the cause of compression of the ulnar nerve. In the author's view, the compression of the nerve is caused by the distal transverse ligament of the fascia antebrachii. By severing this transverse ligament, regeneration of the nerve is made possible.
在五个月的时间里，在所有检查的病例中，作者发现了11例如弗罗泽和弗兰克尔在1908年所描述的小指展肌。它起自前臂筋膜，穿过Guyon管至小鱼际肌块。其血管化和神经支配由尺动脉和尺神经提供。该肌肉必须归属于小鱼际肌肉系统，而在同一区域发现的、文献中经常描述的掌长肌变异则由正中神经支配。此外，文献认为该肌肉是尺神经受压的原因。作者认为，神经受压是由前臂筋膜的远侧横韧带引起的。通过切断这条横韧带，神经再生成为可能。
